organización de naturaleza académica y científica, que promueve los vínculos
entre las diferentes facultades de odontología y con entidades nacionales e
internacionales; tiene como uno de sus principales propósitos apoyar el desarrollo
investigativo de las diferentes facultades.
El Encuentro Nacional de Investigación Odontológica se constituye en el mejor espacio
para que este objetivo se cumpla. Pues permite la socialización de los resultados del
trabajo investigativo dentro de la comunidad académica y profesional, promueve la
discusión con los pares, favorece la Identificación de la fortalezas y debilidades que
cada facultad puede registrar y crea espacios que fomentan el dialogo con el propósito
de promover el trabajo colaborativo.
Cada año el Encuentro es realizado por una de las facultades vinculadas a la asociación.
En la XVIII versión de este encuentro, Manizales-La ciudad de las puertas abiertas- ha
sido la responsable de acoger a las veintiuna facultades que, en este momento, integran
a la ACFO y de crear espacios que favorecen el cumplimiento de los objetivos propuestos
para este evento.
En este marco se desarrolla además, la Segunda Reunión de la Internacional
Association for Dental Research-IADR-, División Colombia. La asociación y
particularmente, la División de Investigación son concientes de la importancia y las
implicaciones que se tienen al liderar procesos que promuevan la internacionalización
de la investigación y este año en particular con la visita de al Coordinador Regional de
la División del Brasil Dr. José Luis Lage-Marques este propósito se hace evidente.
Es importante anotar el significado que este año tiene para la División de Investigación
la realización del III Encuentro de la Red SIF-ACFO, actividad organizada con el
ánimo de promover un espacio de formación para la investigación en aras de realizar
investigación formativa que brinde a los actores, en este caso estudiantes y profesores,
la oportunidad fortalecer su actitud investigativa y unir fuerzas en beneficio de la salud
oral de los colombianos.
Este espacio es de vital importancia ya que permite, fortalecer la acción en red y la
socialización de los procesos investigativos que los estudiantes participes de Semilleros
han desarrollado, con la finalidad de retroalimentar su propio proceso y adoptar una
posición crítica frente al papel de la investigación en la formación universitaria.
En el marco del XVIII Encuentro de Investigación se darán a conocer los ganadores del
concurso COLGATE del presente año; constituyéndose este, en un espacio adicional
que fortalece y promueve la investigación de los jóvenes investigadores. Es importante
resaltar el constante e invaluable apoyo que la empresa COLGATE ha brindado a la
asociación para la realización de este evento. Por esto, considero oportuno agradecer a
los directivos de la empresa COLGATE por todo su apoyo con el fin de fortalecer la
investigación y su desarrollo en las diferentes facultades de nuestro país.
Por otra parte, sería injusto cerrar este aparte, sin agradecer a la Universidad
Autónoma de Manizales por su cálida acogida e incansable trabajo en la organización
de este encuentro; sus esfuerzos hacen posible que todos nosotros podamos reunirnos y
compartir con entusiasmo los procesos investigativos desarrollados.
Gracias a Manizales, y Gracias a COLGATE por su apoyo

Chronic polimicrobial apical periodontitis is related with Porphyromonas gingivalis, Prevotella intermedia,
Prevotella nigrescens, Prevotella loescheii, Fusobacterium nucleatum, Bacteroides forsythus,
Campylobacter rectus, Eikenella corrodens and Treponema sp., which have been implied with the
periodontitis and are considered indicators of risk for progression of this disease (Wolff ET to., 1994;
Genco ET to., 1996; Fleming T., 1999; Marsh and Martin 2000; Lindhe J., 2000). The objective of the
present work is to show to the relation between the anaerobic microorganisms and etiology of the
periodontitis. Eleven (11) samples of patients of the external consultation from Odontolgy Faculty of
Cartagena University, with clinical antecedents of chronic periapical injury, whose diagnosis was non
supurativ chronic apical periodontitis, were put under exodoncia. Dental samples were transferred to
laboratory for microbiological analysis and anaerobic fenotipic identification. Each extracted tooth was
deposited in prefabricated glass with lateral manifold that contained BHI broth (Oxoid), for incubation in
anaerobics jars (Anaerobic System, BR 38; Oxoid Ltd., Hampshire, England) for its identification. This
bacterial growth was inoculated in agar Shaedler (Oxoid) and incubated in anaerobiosis during 24-48
hours to 37°C. The recovered isolated stocks were identified using BBL CRYSTAL. The isolated bacteria
were Streptococcus intermedius (25%), Peptostreptococcus tetraedium (20%), Peptostreptococcus
prevotti (10%); P. mágnum (5%), Lactobacillus acidophilus (10%), Fusobacterium nucleatum (10%),
Bacteroides ovatum (5%), Eubacterium lentus (5%), Streptococcus constellatus (5%) and Actinomyces
viscosus (5%). The isolation and precise identification of anaerobic bacteria in radicular channels is useful
for diagnosis and effectiveness of the treatment of periodontals infections, having in account diversity of
involved anaerobic bacterial species.

Abstract
Objective: To evaluate the response of cultured periodontal and gingival fibroblasts irradiated with low
intensity laser.
Methods: Cultures of human periodontal and gingival fibroblasts obtained from the cell bank of
University of Valle were incubated for 24 hours and irradiated at logarithmic proliferation phase with a low
intensity laser, Photon LASE As-Ga-Al with 37 mW of power, 830 nm wavelength and energy of 375J/cm2.
Evaluation of cell proliferation of test and control cultures was made with XTT ® kit. Percentage of cell
toxicity was measured with LDH ® kit. Cell proliferation was expressed in optic density units or
absorbance and was evaluated at 24, 48, 72, 96, 120 and 144 hours after irradiation.
Results: We did not find citotoxicity of any of the cell lines evaluated with the irradiation protocol.
Proliferation of gingival fibroblasts was higher in experimental than in control cultures, whereas the
proliferation of periodontal fibroblasts was higher in control cultures. We did not find statistically
significant differences between test and control cell cultures.
Conclusions: Citotoxicity test showed that this irradiation protocol is safe for both cell culture lines.
There were no statistically significant differences between or within groups. Effects with this therapy must
be account for future research, to evaluate metabolic, morphologic and physiological changes in other
cells involved in dental movement.

Periodontitis is a pathological response to a chronic infection that appears to be triggered by microbial
biofilms and lead to destruction of tooth support tissue. Aggregatibacter actinomycetemcomitans (A.a.) is
a gram negative cocobacillus that has been associated to aggressive forms of periodontitis. The cytolethal
distending toxin (CDT) is a virulence factor of A.a. which induces cell cycle arrest and modulates cytokine
synthesis in a cell type dependent manner. Gingival fibroblasts (GF) are an important cellular component of
periodontal tissues that play an active role in pathogenesis of periodontitis as immunomodulator through
synthesis of cytokines/chemokines and soluble mediators.
Objectives and Methods: to evaluate the immunostimulatory capacity of CDT in GF by detection of IL-6
and IL-8 production in supernatants from GF primary cell cultures exposed to either wild type A.a. or
cdtABC mutant strain extracts; using a BCA system for cytokine analysis by flow cytometry.
Results: There were not significant differences in IL-6 and IL-8 levels produced by GF challenged with wild
type or cdtABC mutant bacterial extract. However, when response to lipopolysaccharide was not controlled
by pre-incubation of GF with antibodies anti-CD14 and anti-TLR4 before bacterial challenge, IL-8
production was significantly reduced in GF stimulated with cdtABC mutant but not with A.a. wild type
strain.
Conclusions: These results suggest that CDT does not affect directly the IL-6 and IL-8 production by GF in
vitro. Nevertheless, a potential indirect immunostimulatory role of CDT in GF may be associated with other
A.a. bacterial components such as lipopolysaccharide, which has to be studied.

Universidad Nacional de Colombia
Abstract
Introduction: The HSV-1 can remain in the host cells establishing latent infections. During the acute
infection and in the latency reactivation, the HSV-1 alters the expression of genes related with the antiviral
immune response.
Objectives: standardize an in-vitro Trigeminal Ganglia primary cultured system to evaluate the HSV-1
effect on cells and in the immune response.
Methods: the Trigeminal Ganglia of adult mouse were extracted, enzymatically dissociated, cultured and
treated or not with Cytosine Arabinoside (Ara-C) to inhibit the non neuronal cells proliferation. The culture
infection was made at several MOI, and the proportion of cell infected was determined. A plaque titration
of virus yield to culture infected media was carried out. The relative expression of mRNA to Oligoadenylate
Synthetasa 1a and 1b (Oas 1a,1b) were determined by RT-PCR.
Results: the HSV-1 is highly cytopathic as in neuronal as non neuronal cells, even al low MOI. The
neurons are most susceptible to be infected, in spite to being greater number of non neuronal cells in
cultures. The pretreated cultured with Ara-C show a significant reduction of infected cells and in viral
particles, suggesting a residual anti-herpetic effect of this drug. The mRNA expressions to Oas-1a y Oas-1b
were down-regulated by the HSV-1, inducing changes on the expression of such.
Conclusions: this model of primary culture allows evaluating the effect of HSV-1 on cells and determines
its regulation on interferon stimulated molecules. The down-regulation of mRNA by the HSV-1, shows one
of the resistance mechanism and evasion of anti-viral immune response.

Abstract
The knowledge of the Stem cells biology and their potential use in regenerative medicine, are
fundamental to use them as therapeutic agents. Among their classification a denominated Adult
Stem cells population exists with the self renewal and differentiation properties. In order to commit
in a differentiation process Stem cells can be modulated by means of soluble factors that activate
signaling pathways with commitment towards differentiated cells line. The Transforming Growth
Factor Beta 1 (TGF â1) regulates the differentiation and cellular proliferation, toward the skeletal
cell line.
Objective: To determine the in vitro potential of different TGF â1 concentrations to modify the
phenotype of human mesenchymal precursor cells.
Methods: Immunocharacterization by the expression of Fibroblast Growth Factor Receptor 3
(FGFR3), the analysis of cellular differentiation by determining the phosphatase alkaline activity,
and the collagen I expression by RT-PCR.
Results: The percentage of cells that entered S phase was of 11,6% ± 2.10; 20,4% ± 1.31; 29% ±
1,50 for the treatments with 1ng/ml, 5ng/ml and 10 ng/ml of TGF B1. The FGFR3 inmunoreactivity
was located with 1 ng/ml, 5 ng/ml and 10 ng/ml simultaneously in nucleus and cytoplasm. It was
observed that 1 ng/ml of TGF B1 exerted in vitro greater effect on differentiation stage, because
diminished the number of cells that continued expressing FGFR3. During the fluorometric assays
there was an increase in the signal of mesenchymal cells from the Wharton's jelly with positive
alkaline phosphatase activity, and by RT-PCR an increase in the expression of collagen I ARNm.

Investigaciones Odontológicas.
The saliva has an important role in maintaining normal conditions of the oral tissues. Variability in salivary
composition determines its protective characteristics against dental caries. Knowledge of the molecular
content of salival in humans is important to better understand the protective properties of this biological
fluid.
Objective: recognize protein composition in whole saliva of subjects with active caries, history of caries,
and free of caries in Colombian population; by electrophoretic pattern and correlate these results with
clinical diagnosis.
Methods: 145 patients over 18 years old were selected after clinical examinations, and classificated in
three study groups. After signing the informed consent form, whole saliva samples were collected. Total
protein determinations were made using the Bradford method. Individual saliva samples were analyzed
by SDS-PAGE and related with DMFT indexes. The gels were analyzed by Quantity One 1-D software
(BIO-RAD).
Results: Total protein content was higher in female subjects (p= 0.0028). No statistically significant
differences were found between the total protein concentration and absence of previous experience of
dental decay. Salivary proteins present in the majority of individuals were 168, 101, 77, 62, 55, 44 and 39
kDa in size. No association was found between salivary proteins and caries index.
Conclusions: Proteins present in the total saliva samples are similar between study groups indicating no
association between them and the absence of previous dental decay experience.

Abstract
Nowadays, a growing concern exists for the habits in the use of fluoride tooth paste in children less
than 6 years old, since this presentation is one of the main sources of fluoride ingesta in this
development stage and identified as factor of risk for the dental fluorosis.
Objective: To determine the habits in the use of toothpaste of scholar students minors of 6 years old
in a Private School, a District School of Chia and patients who attend to C.O.C. (Colegio Odontològico
Colombiano).
Method: a transversal and descriptive research was carried out by means of a semi structured
interview to parents of scholar students minors to 6 years old in a Private School of Bogotá, a District
School of Chia locality and patients that attend to C.O.C.
Results: Children brush their teeth twice a day (51.4%). The quantity of toothpaste used in the
public school was greater to a “pea-sized“ in a 52.9%, while in the private school and patients of
C.O.C. they used the same quantity to a “pea-sized“; the most used toothpaste was Colgate with a
percent of 85.71%, which has a fluoride concentration of 1450 ppm.
Conclusion: it was found that fluoride concentration used was greater to the indicated in children,
where they used a superior quantity to a “pea-sized“, in the same way it is identified how the social
status and beginning of brushing is related.

Abstract
Objective: The aim of this descriptive study was to determine the prevalence dental caries and
dental fluorosis among 5-to 13-year-old students in Medellin, Colombia. Methods: Data were
obtained from dental examinations of a stratified randomized sample of 1569 students in 2006,
performed by trained and calibrated examiners (Kappa > 0.65). Chi – square, Kruskal – Wallis, and
Mann – Whitney tests were used (á = 5%). Results: The mean (±SD) dmft/DMFT values were 3.3
(±3.9) for the 5- year- old children and 1.42 (±1.8) for the 12- year-old students. SiC Index was
used to determine the group having higher caries experience; mean (±SD) for the 12- year-old
students was 3.35 (±1.9). The percentage of schoolchildren presenting with sound permanent
teeth (DMFT = 0) was 45.2% at 12- year- old students. The prevalence of fluorosis was 81.2% (TFI)
with severity ranging from TF1 and TF7, while in 1998 was 10.3% (Dean Index). Conclusions: The
results indicate a reduce caries prevalence for all ages; however, the phenomenon of dental caries
polarization is already perceptible in Medellin. The fluorosis level found was higher than expected
given the historical data from communities with optimal fluoridation in other countries and
constitutes a public health problem. Health authorities should focused attention and intervention in
both problems.

Introduction: Colombia have a comprehensive salt-fluoridation-programme area with 180 - 220
ppm. The municipality of Saboya is a town with 20 degrees of average temperature and low humidity.
supplied with water from a Suarez river whose fluoride concentration is 0.12 mg/l.
Objective: To measure and evaluate 24-h urinary fluoride excretion by school children 4-6 years old
who were living in urban and rural community a nonfluoridated area in Colombia.
Methods: Twenty-four-hour urine samples were collected from 4-6 year-old children (n = 276) we
record the children's weight, intake of their regular meals was not altered, and we took supervised
collections of urine samples in the morning at school, and parents of the participating students
collected afternoon and nocturnal samples. Urine volume was measured immediately after the 24hour collection and samples of the collection from each child were frozen for transportation prior to
'blind' analysis in the chemistry laboratory at the Javeriana University for fluoride content.
Results: It was found that the mean 24-hour urine volumes were 487.22 ml (SD 17.88) The mean
24-h fluoride excretion was 0.579 mg (+/-0.42), where 39% of the participating children have
fluoride excretion > 0.5mg / 24 hrs. Population living urban and rural area was affected.
Conclusions: The daily urinary fluoride excretion and estimated fluoride intake in these children
must be studied further because appeared to be beyond acceptable limits.

Abstract
Objective: Determine the correlation that exists between the presence of dental caries and the
social and biological risk factors among children of ages 5 and 6 years old belonging to comunitary
5 schools of the Colombian institute of family welfare in Cartagena de Indias.
Method: The study was transversal. The population studied were children ages of 5 years from
comunitary schools of the colombian of family institute welfare of Cartagena. The simple consisted
of 65 children of the 5 schools that were involved in a study of arch growth and developement in the
dental school of the university of Cartagena between the years 2003 and 2004. The variables
evaluated were: presence of dental caries, past history of caries, sistemic sicknesses, diet, oral
hygiene condition, exposition to fluorides, social factors (family profile, educational level, socio –
economic status, life style.)
Results: there was a direct relation between the presence of caries and the frecuency of
carbohydrate, sugar and protein ingestion. There was a high association between the social –
Economic status and the past history of caries, a moderate exposure to fluorized foods, time
watching television, brushing technique, and low assistance to fluorization campaigns. It was not
found a relation between presence plaque index or civil status of parents, obedience to their parents
or ingestion of fats and vegetables.
Conclusions: with the obtained knowledge we can redirect the actions of health promotion and
sickness prevention in this child population. Trying to emphatize in the factors that had relation or

THE FLUORIDE CONTENT OF BEVERAGES OF FREQUENT COMSUMPTION IN
CHILDREN OF AGE SUSCEPTIBLE TO DENTAL FLUOROSIS
Diego Andrés López*, Ángela María Franco, Jeisson Javier Estrada, Jonathan Andrés
Zapata.
Abstract
Since the 1998's the prevalence of dental fluorosis has increased in Medellin, concomitant with a
reduction in dental caries. These changes have been attributed in part to the widespread use of
systemic and topical fluorides. Few studies in Colombia have investigated fluoride exposure from
beverages. Objective: The aim of this study was to analyze the fluoride content of beverages
consumed by children of age susceptible to dental fluorosis. Methods: Several kinds of beverages of
40 commercial brands (bottled waters, milk, natural juices, carbonated drinks, soft drinks and teas),
purshased from supermarkets and groceries stores were analyzed. The fluoride content of all
samples was determined in duplicate, using a Fluoride Ion Selective Electrode. Results: Fluoride ion
concentrations ranged from 0.010 to 4.285 mg/L. The majority beverages presented flouride level
below 0.05 mg/L. The highest mean concentration of fluoride was found in the teas (3.45 ±1.49
mg/L; range 1.54 – 4.28 mg/L). The manufacturers' labelling did not informate about the content of
fluoride concentration. Conclusion: The majority beverages did not reach the fluoride level to be
considering a risk for fluorosis; however some beverages analyzed may be important contributors
to the total daily F intake. Their consumption by children at the age of risk to dental fluorosis should
be avoided. The F content in these products should be informed on their labels.

Abstract
Although several oral hygiene elements help to improve oral cleanliness, an evaluation still needs to
be performed about the development of the child's grabbing and the detail motor skill needed
during that activity. Method: An analitic and cross-sectional study were designed for the purpose of
describing this performance. There were evaluated 155 children, boys and girls between 6 and 10
years old. Two assesments were made, one of oral hygiene through Quigley-Hein Index, and the
other one to mesure fine motor skills through the patterns developed for functionality. Frecuencies,
means, and 2, Anova and Kruskall Wallis comparision tests, were applied for doing the statistical
analysis. Results: There were significant differences between the use of the tooth brush and dental
floss for age and gender (p<0.05). The functionality patterns more frequently absent were the
radial-cubital displacement and wrist rotation, there were observed significant diferences for ages
(p<0.05). Although the relation between this two patterns and the level of oral hygiene were not
significant for the ages of seven to ten years in these children (p>0.05), its evaluation is important
before those ages. Conclusions: The influence of patterns of functionality related to oral hygiene is
clear for the 6 years old children, specially in boys. Even though those patterns regardless in more
advanced ages as a functional pattern, perhaps some motions are not appropriate to accomplish an
adequate routine for oral hygiene. No teaching oral hygiene causes loss in motor skills even after the
integration of those patterns.

Abstract
During endodontic therapy one of the most important steps is the determination of the root canal
working length. The Electronic Apex Locators (EALs) have been designed to determine the working
length more accurately.
The purpose of the present study was evaluate the accuracy of the
electronic apex locators: Root ZX, Foramatron D10 and Bingo 1020, and compare its accuracy to
the actual teeth length under optical light microscope (x 10). Two hundred sixty three root human
permanent teeth were used, sectioning the crown to gain access to the root canal. A first operator
determined the control length (actual length) under optical light microscope; after other three
operators previously calibrated for each apparatus determined the electronic measures having the
position “Apex” like reference. The results obtained (in millimeters) for each EAL were compared
with the control length and were recorded in independent tables to corresponding statistical
analysis. The results showed EALs accuracy of 90,9%. Under the conditions of this investigation
the measures obtained with the three EALs were of similar accuracy.

Abstract
The aim of this investigation was to determine the agreement between the Radiovisiograph and the
Photodensitometer, in the measurement of radiopacity of endodontic materials in aluminium
millimetre equivalents (Al). Based on a pilot study, a probabilistic sample consisting of 43 specimens
of gutta-percha discs was obtained. Each disc had a diameter of 10mm and thickness of 1mm. Xrays were taken using conventional radiographic film or a Radiovisiograph sensor from a distance of
30 centimetres. The radiopacity was assessed by a Photodensitometer on a conventional
radiograph converted into a digital image by a scanner, as well as by the Radiovisiograph Shick and
its software. A high reproducibility and accuracy; ICC >0.8 for both methods was found. Hence, the
Densitometer, as well as the Radiovisiograph are reliable methods to measure radiopacity of dental

Abstract
Dental eruption generally makes reference to the appearance of some part of the tooth over the
surface of the gum looking for contact with its antagonist. During the eruption it would jag. It is
possible to find some chronological disorders like premature and retarded emergencies.
For this reason it was decided to carry out the following study to determine the prevalence of
chronological eruption alterations of the permanent teeth in children from 5 to 13 years old, who
attended at Dentistry Clinic Juan Manuel Mendez Bechara in Montería, during the period between
2001 - 2006. 1202 clinical histories were studied, and 64 cases (5.3%) presented some kind of
alterations.
167 teeth showed chronological alterations, being the delayed emergency the most frequent
alteration, 56.8%. The most affected population corresponded to males, between 8 and 9 years old,
the second transitional period, was the most affected as well. The lateral maxilar incisor had the
highest prevalence (12). It was found a significant difference between the literary reports and the

Abstract
The aim of this study was to undertake a clinical stability evaluation of the mini implant used as bony
anchorage for the upper molar intrusion.
Thirty four Leone® stainless steel mini implants were used (four dimensions: 1.5x10mm,
1.5x12mm, 2x10mm and 2x12mm), in nine patients and a total of 18 teeth to be intruded.
The insertion procedure was performed according to the manufacturer's recommendations.
The stability of the mini implants was evaluated monthly measuring its clinical mobility by means of a
digital Boley gauge. It was found that all the mini implants placed were effective as bony anchorage
to carry out the intrusive movement in spite of the appearance of mobility in some of them, which is
indicative that mini implant can have certain movement range without losing its clinical effectiveness.
It was found that variables such as the force applied to the mini implant, the dimension (length and
diameter) and the insertion torque are not related to stability. Conversely, it was found that mini
implants located in the palatal mucosa were more stable than those located in the vestibular area.
The keratinized gingiva presents better clinical conditions (less inflammation and hyperplasia) than
the alveolar mucosa for the mini implant placement to secure the stability through time. In the
radiographic evaluation were found no signs of root resorption in any molar.
Key Words: Orthodontic anchorage procedures, tooth movement, molar intrusion, mini implant stability.

Abstract
Actually present Orthodontics has new materials that facilitate to the professional a suitable
handling of tactically important points such as the adhesion, aesthetic, resistance to diverse forces
and biocompatibility, being these vital factors in the search of a successful treatment. Considering
the direct relation between the shear bond strength, the adhesion, the types of force generated and
the physical and chemical characteristics, the objective of the present study was to compare the
shear bond strength of titanium braces and stainless steel braces at torsion moments, thus was
made a study in Vitro with 30 titanium braces and 30 stainless steel braces using 60 human
premolars, in which they were submitted to torsion moments with stainless steel wires of
0.019x0.025 Ormco corp. With the aid of an Instrom machine specifically adapted for this study that
allowed evaluating the shear bond strength for this two materials.

The aim of the present study was to observe the possible relationship of the esqueletal malocclusion
with the longitude and angulation of the cranial base taking in concern the sex and to compare three
different analysis to obtain the malocclusion classification. 200 cephalometric x-rays of patients
from 8 to 12 years old were taken and divided in four groups having in concern the British standard
classification of incisor malocclusion, each group was also divided by sex. Longitudinal measures of
the cranial base; (S-N; Ptm-N; Ar-N) and angular measures ( S-N-Ba; S-N-Ar) were compare whith
class I, II and III (basal arch by Sassouni and incisor classification). The Pearson analysis of
correlation the T of Bonferroni were utilized and ANOVA of two ways between sex and incisor
classification . The result showed a statistical difference in the classification of the esqueletal
h
malocclusions
among the three used evaluation analysis (ANB, basal arch of Sassouni and Incisor
Classification) . Being single agreement in ANB and Sassouni in Class II and in incisor classification
and Sassouni in class III. The results of the study don't support the theories on a strong influence of
the angulation and the size of the cranial base in the etiology of the malocclusions, contrary, it seems
that the conformation of the malocclusions is much more complex and not an isolated factor but
rather a combination of structural factors and differences in maxilo mandibular growth that on the
whole act offering proportion or disproportion in the sagittal relationships.

Abstract
Introduction: The criterion to decide to make early treatment in class III malocclusion, is not yet
clear, depend to identify individuals pretreatment characteristics that can use as predictors for
malocclusion successful correction.
Objective: The purpose of this research was to identify the predictor capacity Petrovic's method on
the determination of the success of the treatment with maxillary protraction.
Materials and Methods: 30 patients treated with facial mask whit 2 x-rays one before and one
after the mask were chose. This X-rays were digitalized and measured with the software, cefalometro
(error p 0.417), The patients were classified in success's groups according to the cefalometric
variations observed. The data base was analyzed according to fisher's exact test, stepwise,
univariated, and discriminant analysis.
Results: 55.56% of the persons for whom the auxological category predicted as badly grown,
presented not successful treatments, 50% individuals with a prediction of regular grown, presented
a moderated response, and the 25% individuals with good prediction of grown presented successful
results. (p value 0.4229). Additionally, the discriminant analysis done between the initial variables
and the system of classification of success dropped as predictor variables SNA, ANSMe and GoGnPal
with a sensibility of 50% for the non successful group 62.5% for the successful, and 100% for the
moderated.
Conclusions: It's concluded that the ability to predict of the Petrovic method is 57.71% and that the
variables SNA, ANSMe and GoGnPal have a close relation with the success of the treatment with facial
mask on patients class III skeletal Malocclusion.

Abstract
The Objective of this study was to determine the effectiveness of the Moyers and Tanaka-Johnston
space analysis in the prediction of the mesiodistal dental size of unerupted maxillary and
mandibular permanent canine and premolares, in the patients assisted in the clinic of orthodontics
of the F.U.S.M.A Samples of 76 study models were taken from the clinic of Orthodontics of this
university. The sample taken was 49 female and 26 male, in permanent dentition, that fulfilled the
inclusion approaches, to which the predictions of Moyers and Tanaka-Johnston applied and the
results were compared with the real measurements of the mesiodistal dental size of maxillary and
mandibular permanent canine and premolares taken directly from the study models. The
instrument used to carry out the measurements was a digital caliper; The values were obtained
using the statistical analysis T Student. This test was carried out with the Software Statgraphic. The
results indicate that the difference was statistically significant among the values predicted by the
method of Moyers and Tanaka - Jonston, when being compared with the real mesiodistal diameter
of canine and premolares in female patients. On the opposite in the male patients the differences
that were presented were not statistically significant, thus one concludes that when using these
space analyses in the patients of the orthodontic clinic of the University Foundation San Martin have
limitations in the results and the influence of sex is marked.

Autonoma University of Manizales
Abstract
Aim: To determine the frequency and characteristics of ectopic eruption of the first permanent
maxillary molars in children between 6 and 9 years old.
Materials and method: A transversal-correlational descriptive study that was carried out with the
clinical records of 48 children (male and female) who met the inclusion criteria: 24 of them with
ectopic eruption and 24 in the control group. The frequency for the type of eruption, the
reabsorption of the distal root of five temporals, the position of 16 and 26, the length of the upper jaw
and the type of anteroposterior occlusion were stated. Chi square for the type of eruption and
radicular reabsorption as well as Student's T test, among the angular and longitudinal measures,
were applied.
Results: In the study group, 22 cases presented bilateral ectopic eruption and 2 of them, unilateral
ectopic eruption. Reversible ectopic eruption was associated to slight reabsorption in the distal root
of the fifth temporal (p<0.05). Ectopic eruption of predominant 26 was reversible and was
statistically related to (p>0.05) severe reabsorption in the distal root of 65. There was a statistical
difference (p<0.05) between the angle of 16 and the NPL (cephalometric points) distance of 16, thus
being smaller in the study group.
Conclusions: Reabsorption was slight for the distal root in the cases of reversible ectorpic eruption
of 16 and mild-to-severe reabsorption in the cases of irreversible ectopic eruption in 16, (p<0.05).
The mild radicular reabsorption of the second temporal molar was related to irreversible ectopic
eruption of 26.

CES University.
Objective: A controlled randomized blind clinical trial was made to evaluate the effects of a rigid occlusal
splint on the growth of the maxillary alveolar bone, the dental wear and bruxism signs.
Materials and Methods: 36 subjects between ages 3 to 6 were included, with complete primary
dentition and dental wear. They had a high anxiety level plus 2 or more signs of TMJ pathology and their
guardians reported bruxism. The subjects were randomized and distributed in a control and an
experimental group. In the experimental group, a rigid occlusal programmed splint was installed which
they used until the beginning of their mixed dentition. Casts of the upper arch were taken every 6 months
during the deciduous dentition, in which dental wear was digitized and the arch dimensions were
measured. The anxiety and TMJ tests were taken again to the control and experimental group at the end
of the study. Data was then analyzed using the t-student test and Wilcoxon rank sum test.
Results: The dimensions of the maxillary arch, dental wear, anxiety level and TMJ pathology did not have
any statistically significant difference. Bruxism or tooth grinding noises reported by parents decreased in
both groups.
Conclusion: The use of a rigid occlusal splint did not affect growth of the maxillary bone, but neither did
it diminished the TMJ pathology signs, anxiety levels nor the amount of dental wear on the subjects.

Abstract
Introduction: The cephalometric characteristic heritability of class II malocclusion is a controversial theme. It is
assessed from cephalometric variables in monozygotic and dizygotic twins and between parents/offspring and
among siblings.
Objective: estimate the genetic contribution, through cephalometric variables of class II division 1
malocclusion; between parents (including uncles and aunts) and offspring and among siblings.
Materials and Methods: in the lateral x-ray, we take verticals and sagitals skeletal variables, and dentals
variables. From 43 subject class II division 1; 5 men and 4 women fulfilled the inclusion approaches; from whom
all the possible relatives were included. The x-rays and its measurements were digitized. The calculation of the
systematic Error by means of test paired t and p<0.05. Heritability: among parents/offspring was used,
h 2i =
2 * bi and among siblings h 2 =
2 * ri ; a graphic method was also used with polygons type Downs.
Results: heritability statistically significant if p<0.10. Among parents/offspring; were inheritable: vertically:
inferior former facial height (ANS-me *), inclination mandible plane (SN-PM) and axis "Y". Sagitally: maxillary
longitude (PNS-ANS *), SNA and SNB. Dentally was not heritability. Among siblings; vertically: inferior former
facial height (ANS-me), longitude of the branch (Ar-Go), angle of maxillary inclination (SN-PP *), axis G * and "Y",
and posterior facial height (S-Go). Sagitally: SNA, SNB. And dentally: inclination of the incisive with palatine plane
(Is-PP) and with SN (Is-SN). (*more inheritable).
Conclusions: our discoveries agree with previous studies: bigger vertical genetic control that sagital, little dental
heritability among parents/offspring. Bigger heritability among siblings; it can be due to the effect cohabitation.

Graduate School of Orthodontics. School of Dentistry. Universidad El Bosque
Abstract
The purpose of this study was to determine the accuracy of the slot height of new standard edgewise
and straight arch brackets of four different companies and to compare the slot size of standard
brackets. A total of 830 brackets were chosen as the sample by a probability method; 134 brackets
from each company for the edgewise standard technique with an 0.018-inch slot (American
Orthodontics, OrthoUSA) and 281 brackets from each company for the straight arch technique, Roth
prescription, with an 0.018-inch slot (GAC) and 0.022-inch slot (Ormco), which were subdivided by
dental group due to the differences in torque and angulation for each type of tooth.. The tolerance
range was established based on the Creekmore data of 0.0182 to 0.0187 inch for a 0.018-inch slot
and of 0.020 and 0.025 inch for a 0.022-inch slot. The results showed that the slot height of the
evaluated brackets did not coincide with the data reported by the manufacturer. The average slot
(0.01970 ± 0.001516) of the American Orthodontics brackets was the least accurate according to the
maximum range of the reference. For the straight arch (preadjusted appliance) brackets from GAC,
it was found that the lower incisors and lower canines presented the most variation in their average
values from the reference value, while in the straight arch brackets from Ormco the same happened
for lower canine, first and second-lower premolars. This variation of the slot height should be kept in
mind due to the direct implication it has over the control of the final dental position.

Abstract
The purpose of this study was to compare the effects of recycling on the load-deflection
characteristics that include slope of the loading, martensitic phase, transformation phase and
super-elasticity, of the nickel - titanium alloy wire, subjected to two cycles of clinical use and cold
or heat sterilization. 70 preformed nickel titanium wires of 0.016 inches of the 3MUnitek ®
Corporation Monrovia California were analyzed, used in the patients of the dental clinic University El
Bosque, Bogotá. A procedure of randomized was carried out, separated into 2 groups: Cold and heat
sterilization (n = 35 wires for each group). The wires were analyzed in three times: as-received
condition (T0), 4 weeks of clinical use and sterilization (T1) and 8 weeks of clinical use and
sterilization (T2). The changes were analyzed by means of a flexion test using a transducer of force
Instron.
The findings showed that the nickel - titanium wires when were subjected to recycling and
sterilization presents changes in the values of the slope of the loading and unloading. During the
phases of unloading of the load-deflection curve was observed that in the martensitic phase,
significant differences existed among the times (T0 vs. T1 and T0 vs. T2). Additionally, the wires
heat sterilized showed a tendency to be less rigid than those that were cold sterilization.

FOR ORTHODONTIC
Paula Vanegas, Griselda Serna, Nuria Vergel, Lina Mariño, Nidia Cuartas
Abstract
Purpose: To make the technological design of a model of utility of the head of mini-implants used in
orthodontic.
Methods: Technological design whose object of study is the head of the mini ones - implants. The
analyzed categories were angles of the head, diameter of slot, autoligate's system, closes and
opening of the cover, neck, orifices and length or profile of the head of the mini implants. In
investigations made in Colegio Odontològico Colombiano with mini implant, the clinical necessity
was determined to improve the conditions the bound one and to give greater versatility. As an initial
plane of these did not exist, a rise on scale 12:1 was made. From this, five sketches with different
modifications were designed: hexagonal neck, head with 4 fins T, autoligate's system, diminution
of the size for greater comfort of the patient. Finally a last design was obtained that responded to
the previous necessities.
Results: The obtained final design displayed the following characteristics: An overall height of the
head to the neck of 2,83 mm, distributed in 1.75 mm and 1,08 mm respectively, with wide of 3,48
mm and one depth of 3 mm. Each fin T that conforms the head of mini-implants measures 1mm of
height by 0,93 mm wide and presents/displays a superior orifice whose diameter is of 0.2mm.
Conclusions: The design of a model of utility of the head was developed of mini-implants with a
autoligate's system, which offers a greater versatility in agreement with the necessities of the
treatment; since it displays a hexagonal neck that will possibly improve the subjection to the
screwdriver. The form of the fins and the presence of orifices in them will facilitate the positioning of
different additions from bound.

Chronic renal deficiency is the slow and progressive loss of kidney function. .the oral systems that
are directly related to this disease are xerostomia (dry mouth) which is accompanied by
hiposalivation (a decrease of saliva fluid). This causes complications for the oral health of the
patient such as, periodontal illness, fungal bacterial infections, and difficulty speaking, swallowing
and ingesting liquids. Adversely affecting the patients life. However there has not been any studies
that show the relationship between xerostomia (dry mouth) and hiposalivation (a decrease of
saliva fluid).
The before mentioned, made us run some studies of hemodialysis patients with chronic kidney
deficiency to show signs of xerostomia. All patients were studied in a state of rest and activity. The
average level of saliva found among patients in the state a rest was found to be 0.342ml/min and
those in a state of activity were 1.109ml/min.demostrating that xerostomia is associated with
hiposalivation in the state of rest with an Odds ratio = 2.3 and RR of 1.23, but there was no
association between xerostomia and hiposalivation in the stimulated state with an Odds ratio = 0.75
and RR of 0.93 . Thus it can be concluded that hemodialysis pacients with chronic deficiency show
signs of hiposalivation with or without the manifestation of dry mouth.

Abstract
The main problem for the forensic odontologist during the first hours after death is the limited oral
opening due to rigor mortis developed in the masticatory muscles.
Objective: To determinate the efficacy of sodium bicarbonate in the reversion of rigor mortis.
Method: An ex-vivo experimental design was developed. Forty unidentified cadavers autopsied at
the Instituto Nacional de Medicina Legal y Ciencias Forenses of Bogotá were selected and divided
randomly in two groups, an experimental group (sodium bicarbonate) and a control group (distillated
water).
Based in the muscular pH found in 10 cadavers (ph:6.0), the sodium bicarbonate concentration was
established in 0,01M. The oral opening was measured previously before the injection of the
substances was performed, 5 Ml of the substances were injected extraorally in the masseter and
temporal muscles bilaterally, after this, the oral opening was measured every 60 minutes until an
“useful” opening was achieved (30 mm). The maximum force applied was standardized in Newtons
with a Molt mouth opener previously calibrated with a dynamometer.
Results: The final oral opening achieved with the sodium bicarbonate 0,01M was significantly
bigger than the one obtained with the distillated water (p 0.000). At 3 hours the bicarbonate
produced an useful oral opening of 30.9±5.5mm.
Conclusion: Sodium bicarbonate accelerates the reversion of mandibular rigor mortis and
represents a non traumatic, inexpensive and effective method to achieve postmortem oral opening.

Abstract
Objective: Is to determine the presence of the VHH-8 in Kaposi´s Sarcoma in patients HIV
positive of the ESE Simon Bolivar Hospital of Bogota.
Method: A transversal descriptive study was carried out in 25 blocks of paraffin study samples
diagnosed with Kaposi´s Sarcoma in HIV positive patients
of the ESE Simon Bolivar Hospital of Bogota. These were analyzed in a virology lab of the University
El Bosque using a PCR test determining the presence or absence of
the herpes virus type 8 ( VHH-8 ).
Results: Of the 25 samples of HIV positive patients with Kaposi´s Sarcoma included in this study,
the average age was 36.32 +/- 6.12 years old ( range of 27 to 48 years ). The sexual preference is
significantly associated to the socioeconomic status.
The most affected area is mouth and extremities. In the oral cavity the most common place was
hard palate, followed by tongue, soft palate and lips.
Conclusions: The sociodemographic factors studied were significant for this study.

Abstract
Introduction: The facial reconstruction in forensic identification is based on the creation of an
image bi or three-dimensional of an individual from his osseous structures; nevertheless in the cases
in which the mandible is not present, for being a bone independent from the rest of the cranium, the
above mentioned method presents limitations.
Objective: The aim of this study was to develop by means of neuronal networks, a model to
estimate the mandible morphology, from dimensions of cranium and maxillary structures.
Materials and methods: We use frontal and lateral X-ray digitized of 50 men and 50 women, Class
I of Angle, between 18 and 25 years; we measured cranium, maxillary and mandible dimensions. A
model of supervised neuronal networks was constructed from 11 prediction craniomaxillar variables
and 11 explanatory ones, with which different mandible dimensions were estimated; later we
calculate the mean errors of the above mentioned estimations with confidence intervals to 95 %.
Results: The mean error of estimation was small (<0.8 cm and <1 º), for the most of the estimated
variables, demonstrating the usefulness of the neuronal networks method to forecast the jaw
morphology from cranium and maxillary dimensions.
Conclusions: The use of the neuronal networks showed to be effective for the prediction of
variables of size and position of jaw, from variables of position and size of cranium and maxillary.

Abstract
This article presents a description of rapid prototipyng technology applied to the medicine,
especially to craniofacial problems. At the same time, describes a specific application with the
purpose of create scientific evidence at national level, from the simulation surgery to insert four
screws, which are constituted in the base of implant-supported fixed prosthesis. The surgical
procedure was made on a plastic jaw made using rapid prototipyng technology, by means of which
solid models are constructed in 3D by addition of material. Mandibular geometry was obtained from
biomedical images processing of an adult woman, totally edentulous and with mandibular bone
resorption of alveolar apophasis. This process was made using GIB_Points_3D software, developed
within the present work. This software generates a text file with 3D cloud points of the jaw and later
it is exported to the commercial software ProEngineer Wildfire 3.0, from which a STL standard
format file is generated. This file is compatible with most rapid prototipyng machines. The
technology used for 3D impression was FDM-“Fused Deposition Modeling”. It was obtain a jaw
plastic model, with anatomical and dimensional high quality, using technology available in
Colombia. In addition, the implant-supported fixed prosthesis surgical procedure was simulated
successfully.

Abstract
Scientific articles (24) identify usefulness of homeopathic medicines in treatment of stomatognathic
system. Two tables were established: the first one relates 55 homeopathic medicines with
pathologies of the stomatognathic system; the second one counterrelates pathologies with
medicines. Literature available in different languages includes: bibliography reports, controlled
clinical tests, reports of cases and cross section studies. 70% of controlled clinical tests showed
effectiveness; 10% showed null effectiveness; in 20%, effectiveness is doubtful due to the
methodologic design. Homeopathic treatments were effective when made with patients previously
individualized; this fact agrees with the thought proclaimed by the beginners of the homeopathy.

Abstract
Objectives: To describe how the diverse dental tissues (enamel, dentin and cement) and four
dental materials (amalgam, composite, glass ionomer and zinc oxide modified cement) react after
high temperatures exposure. This to determine those reactions can be used to identify dental
human remains after burning of fire exposition (200ºC, 400ºC, 600ºC, 800ºC, 1000ºC, 1200ºC).
Methods and materials: An experimental in Vitro study was performed to determine physical
macroscopic and microscopic changes in dental tissues and four dental materials, using 199
extracted teeth after high temperature exposition.
Results: The dental tissues and the four dental materials evaluated showed high resistance to high
temperatures without great apparent variation in their physical structure. This feature allows both
dental tissues and materials to help forensic identification, however small physical changes were
present that generate dimensional expansion, fissures, cracks, fractures and color change.
Conclusions: This study determine that hard dental tissues and four dental materials are able to
resist high temperatures without high physical variants that may allow further forensic identification
after fire exposure.

Abstract
Various investigations have been conducted in criminology using a labial print pattern, and
comparing it with prints collected from suspects or victims, but there have been complications with
the material of choice for print collection. Also, for reading and interpretation of samples, it is
necessary to divide them into multiple quadrants and millimetrically observe each one of them;
procedure which may lead to misinterpretations and errors even under trained eyes, given the vast
quantity of information in the sample to be examined. Another limitation of the queiloscopy method,
is the storage of samples obtained, with time, the samples deteriorate and the patterns become
distorted and dull, limiting observation time and long-term storage, hindering future analysis and
comparisons. For this reason, the first phase of the project QUEILOSOFT was developed, and it was
the digitalization of a labial print. With the use of Matlab, a labial photography was divided into
eighths for a more precise visualization and detailed reading. Afterwards, Matlab was chosen
because it is more powerful, versatile and user-friendly when it comes to programming, and for being
the key tool in investigation, since it is compatible with scientific advances and work in laboratories of
I+D. Thus solving the engineering problems presented in the development of innovative products.

Abstract
Objective: To evaluate the effectiveness of physiotherapy to improve the head posture and reduce
the signs of bruxism in a group of bruxist subjects.
Materials and Methods: A blind randomized clinical trial was performed. All the subjects were
three to six year old, were healthy, had normal facial morphology and class I occlusion. The
individuals were included in the study when they assessed the ASDA criteria for bruxism; they
presented high level of anxiety, two or more signs of temporomandibular disorders and dental wear.
For each child, a clinical, photographic and radiographic evaluation of the head and cervical posture
were realized with standardized techniques. The dental wear was processed in digital format. The
children were randomized in an experimental (n=13) and a control (n=13) group. A 10 session
physiotherapeutic intervention was applied to the children of the experimental group. Afterwards,
the cephalogram, the clinical and photographic evaluation of the head posture and the dental wear
were measured. Also the anxiety, The TMD and the report of bruxism by the guardians were
evaluated again. The data were analyzed with the t-test, the wilcoxon test and the stepwise
likelihood ratio method.
Results: The subjects of the experimental group showed statistically significant improvement in
the natural head posture. The anxiety, the dental wear and the guardian's report of bruxism
reduced as well. TheTMD did not reduce.
Conclusion: The physiotherapeutic intervention showed to be efficient to reduce the signs of
bruxism and to improve the head posture in the studied children.

Methods: A group of 10 children within 3 to 12 years old was selected from those who had been
attend at the Universidad del Valle Dental School Children Clinics at 9° and 10° semesters to whom
“posterior dental cross bite” had been diagnosed. In order to confirm podal alterations a feet print
was taken for each patient. An expert trained physiotherapist studied each footprint and diagnosed
podal physical troubles like varo foot, cavo foot, additionally she observed legs troubles that could
have repercussions on the pelvic waistline and on the spine waists and, trough them, on the
stomatognatic system, especially on the Cranium Mandibular Joint function.
Results: 60% of the selected children (6 patients) had unilateral posterior cross bite; 1 patient show
typical plain feet (10%) and 8 (80%) patients had “cavo feet” plain feet variety.
Discussiòn: In Colombia there no similar studies so it is impossible to do some serious discussion
related to this pilot study. But when the international literature is revised there are some similar
studies that could give support to preliminary comparisons.

Abstract
As professors of odontopediatry in the Dental Faculty of Universidad Nacional de Colombia we have
perceived some difficulties in the clinical practice of the students, especially when they apply theory.
The objective of this work is to observe some pedagogical practices and to use them as a tool for
further analysis that will help the process of teaching.
The methodological approach of this project corresponds to the qualitative ethnographic information
that used observation as a method to collect information in a sample that was made out of three
pedagogical practices. The data was obtained from film recordings of the classes, notes from the
observers and these were complemented with student and professor surveys. Amongst the results of
the interpretation of the data some situations that interfere with the learning process were detected.
These issues work as a reflective tool that help to find answers to the problems that the teaching
method has. Conclusions were classified in seven groups. One of the most important conclusions that
this project has is the suggestion for a revision of the curriculum that focuses mainly on evaluation as
a control tool that is not taken as fundamental in the formative process of the student. It is necessary
to enhance the comprehension and the learning process amongst the students and to focus the
curriculum more in the clinic as a space for the building of knowledge and not as a simple place where
knowledge is applied.

DENTAL CARIES IN EL SALVADOR, FIRST CRITICAL ANALYSIS ABOUT
CARIES PREVALENCE AND ORAL HEALTH POLICIES FROM
BIOPSICOSOCIAL PERSPECTIVE.
Néstor, Rojas, Ingrid Mora y Camilo Duque
Abstract
The critical analysis of dental caries epidemiology in El Salvador is part of the project “Dental Caries
World Epidemiological Map of Children at School,” developed by the Dental Faculty at the Universidad
El Bosque.
WHO data shows a significant decrease of caries in developed countries during the last three
decades. In developing countries, the situation is not so promising —although if the policies and
projects of the WHO would be applied, the general objectives could be reached.
Apparently, the historical situation of El Salvador doesn't seem to follow the same trend as in other
developing countries.The purpose of this study was to analyze the caries in El Salvador by integrating
the evidence achieved in descriptive epidemiological studies with the perspectives gained by critical
or social epidemiology.
The result is a critical analysis of the current epidemiological studies of caries in El Salvador and an
explanation of the epidemiological shift based on the analysis of the historical and social changes in
the country during the last decades. The general conclusion is that caries in El Salvador can not be
considered solely by biological explanations It demands a deep knowledge of the social and historical
process that definitely affects dental caries and also put in evidence the social interest implied in the
implementation of oral health international policies in the field of dental caries.

and TLR´s in activated monocytes in patients with periodontitis when compared to healthy subjects.
The study population included eighteen subjects diagnosed with generalized chronic periodontitis and
generalized aggressive periodontitis, and six periodontal and systemically healthy subjects.
We took peripheral blood samples, for the isolation of monocites and identification of TLR2, TRL4, TNFá,
ILâ and IL6 by flow cytometry and C reactive protein levels. The level of cytokine expression and
membrane markers between the evaluated groups, demonstrated significant statistical differences for
TNFá, TLR2, TLR4 on CD14/HLADR+ monocytes, nevertheless there where no differences found among
periodontal diagnosis. We evidence a condition of a basal stimulus for cytokines which in fact permits a
maintained expression level of activated monocyte markers (HLA-DR), TLR 2 and TLR 4.
These findings reflects the capability of each individual to resist in a natural way to different bacterial
threats associated with this disease following a systemic response.
The C reactive protein don't shown statistics differences between the evaluated groups which could be
related with the cytokines concentrations in our study.

Abstract
Clorhexidine (CHX) has been commonly used as a quimiotherapeutic agent for conventional and
surgical periodontal therapy. zzThe objective of this investigation is to evaluate the effect of CHX on
proliferation, cell cycle and apoptotic morphology of human gingival fibroblasts (HGF) exposed to
this agent on different times and concentrations.
Primary cultures of HGF were obtained from periodontally healthy patients from the dental clinic of
the Javeriana University, Bogotá- Colombia. The experiments were done on culture plates with cells
incubated at 37ºC and 5% CO2 during 24 hours, using a different plate for each interval of
observation of the effect (24, 48 y 72 hours).
Then the different concentrations of CHX were applied (0,001%, 0,0005% y 0,00025%) and
incubated for 30 seconds under normal culturing conditions. Control group was maintained on
DMEM+ SFB 10% complete medium only.
For the proliferation test the colorimetric MTS test was done and apoptotic morphology was
observed under the fluorescence microscope. The results showed cell viability alter 24 hours, a
greater number of cells with the CHX treatment; cell death by apoptosis, even though the number of
apoptotic cells was limited.
From these results it is possible to conclude CHX concentrations used do not have a significantly
statistical effect on healthy HGF viability.

Abstract
Objetive: To compare clinical and microbiologic changes over microflora subgingival in low income
patients with chronic periodontitis who received treatment with hand instrumentation with or without
ultrasound therapy. Method. An experimental study was designed, a total of 19 voluntarie patients
with chronic periodontitis from Universidad Cooperativa de Colombia - Pasto Dentistry School
Clinical Center were included at it. These patients were divided into A and B group. The patients who
belonged to the A group were treated with a hand instrumentation and the B group was treated with a
hand instrumentation and ultrasound therapy.
Results: After receiving the manual periodontal therapy, the gain of attachment level was 0.5mm
(p<0.05), the gingival bleeding reduction was 8%. The microbiologic changes revealed a moderate
polymorfonuclear neutrophil reaction in 33% and slight reaction in 67% of the periodontal pockets.
There were low count of Gram-negative Coccus (GnC) in 16% and Gram-negative Bacillus (GnB) in
25% of these places. In the hand instrumentation with ultrasound therapy, there was a gain of
attachment level of 1.4 mm (p<0.05) in the deep pocket. The gingival bleeding reduction was 43%.
This therapy showed a moderate polymorfonuclear neutrophil reaction in 57% and slight reaction in
43% of the periodontal pockets. There were low count of CGn in 28% and BGn in 57% of these
places.
Conclusions: The hand periodontal therapy produced more gingival microflora changes, while the
hand instrumentation and ultrasound therapy reduced more the bleeding. Due to the two therapies
produced different clinical and microbiological changes, it would really be important the
professionals use hand instrumentation and ultrasound therapy in these patients.

Antioquia University
Abstract
Abstract: The aim of this study was to compare, in vitro, mechanical strength of internal and
external hexagonal systems in implants submmited to compressive, flexion and compressionflexion forces.
Material and methods: 18 assemblies were used, internal hex Renova®* implants (IC) and
external hex RBM®* implants (EC) (3.75 x 13mm) of 9 implants each. Samples were testing by an
Instron® universal machine and submitted to static progressive load with vertical (0º), angular
(45º) and horizontal (90º) force applied until deformation occurs.
Results: the greatest values for elastic limit load were with vertical load (0º) in the IC group
(1733.5N) and EC (1619.5N) and minimun values were for load horizontal (90º) in IC and EC with
267N and 226N respectively. The group of IC presented results more homogeneous in accordance
with the variation coefficient [<20%], mean while the EC group showed greater variation
coefficient.
Discussion: the IC tend to have higher elastic limit load. Besides, the fracture zone showed different
appearance, indicating that each system has different answer under load. In that way, this
difference could be representative under
cyclic load.
Conclusion: From the experiment, there were not significant distinctions between both
connexions, but the wide variation found in some tests and the appearance of the fractures zones
give an indication of the different behaviour between connexions when charged is applied.

Abstract
The purpose of this study was to establish which of the two adhesive techniques, full etching and self
etching, holds the highest degree of micro filtration in the gum cave margin of class II cavities with bevel
on the enamel, used two commercial manufacturer (ivoclar-vivadent®- voco®).
The probabilistic sample size was 76 boxes per group for a total of 304 boxes in 152 premolars, recently
removed due to orthodontic and/or periodontics reasons, healthy, with no enclosing and without a
profuse cervical root concavity. The MOD cavities were prepared with a standardized technique.
The flat bezel with a 45° angle and with a length of 0.5 mm on the cave superficial angle of the enamel
along the mesial, distal and gingival walls. The prepared boxes were randomly distributed in 4 groups;
Group 1: self-etch primer Adhese plus Evo Ceram (Ivoclar Vivadent®) resine; Group 2: Full etch primer
Total Excite plus Evo Ceram (Ivoclar Vivadent®) resine; Group 3: Self-etch primer Futurabond NR plus
Grandio (Voco®) resine; and Group 4: Full etch primer Total Solobond M plus Grandio (Voco®) resine.
The enclosed teeth were set under a 500 cycle thermocycle between 5 and 55°C.
Afterwards they were sealed with cianoacrylate along all the surfaces save for the gum margin and they
were dipped in a solution of blue methylene for 24 hours. They were then covered with an epoxic resin to
be selected with a microtome in the meso-distal direction, obtaining a palatine and a vestibular half in
each box, which was then photographed with a digital camera pixeled on a 20 X microscope. Payne's
(1999) microfiltration index was used to determine the degree of microfiltration.
Conclusions: There is a considerable statistical difference in the microfiltration with enamel margins
between the full etch primer and the self-etching primer from the same brand, showing a lower degree of
microfiltration in the full etch technique.

The objective of the present ex- vivo experimental study was to compare the performance of two
adhesives of nanotecnología under tensil force and compressive resistance in a sample of 102 third
molars just extracted and with crowns and root integrity of its hard tissues.
Cuts in the oclusal surface for the tensil strength were done and cuts in the labial surfaces to measure the
compressive resistance. Randomly 2 groups of 51 molars were made for each test disinfection protocol
based in immersion in cloramina T to 4% during 4 to 24 hours and permanent hidratación in distilled water
until the day the tests were done. The sample preparation for the tests included the elaboration of
retentions in the root of molars with orthodontia wire calibrates 0.16 x 0.22 and the manufacture of dies with
epóxica resin to receive the jaws of the Instrom dynamometer. Also each specimen had a wire retentive
addition placed between the adhesive and the resin to test the tensil force.
Test of compressive strength did not need additional retention. The used adhesives were the Single Bond 2
of 3M ESPE and PRIME and BOND NT of Dentsply in combination with the resin Filtek Supreme Z 250 with
nanoparticles which were used applying the protocols of handling recommended by the manufacturer.
The statistical analysis of the results became by means of the tests of T Student, Mann Whitney, and
Normality of asymmetry, Curtosis, Shapiro -Wilks and Shapiro – France, It means that tensil strength and
compressive resistance do not present satatistical significance among the adhesives tested.
In conclusions, it is clear that the new technology (nano) improve the physicals properties, the sthetics,
brithnes, marginal seal, translucent effect, lasting and low cured contraction

Jose manuel fernandez chaves, Viviana lea waich
Abstract
The intention of the investigation was to develop a device capable to separate the tongue during the
surgical acts to replace a manual action by an instrument that did not need to be manipulated by an
operator.
The plan of work of the project was based on the accomplishment of two prototypes denominated A
and B, by means of scale models elaborated in cardboard, cork, plastilina and acrylic.
For the design anthropometric measures were taken into account such as: the height of the
mandibular oclusal plane to the floor of the mouth, the distance between first left and right molars,
in addition to the anteroposterior distance available to place the mouth opener; these scale models
were digitized through 3D design programs like the Rhinoceros to obtain a better visualization of
the devices.
Two prototypes were obtained, that highly demonstrated through tests to be functional, the
prototype A: type block and the B: type means. The Waich, handsfree tongue retractor is an
instrument designed to ease the surgical processes, opening the mouth and separating the tongue
without been held by the assistant.

CARIES LESIONS: IN VITRO STUDY
Martignon S, Zarta OL, Luna LE, Huertas MC, Zuluaga AL
UNICA–B (Caries Research Unit, Universidad El Bosque)
Abstract
Introduction:The sealing with adhesives of incipient proximal lesions in young adults has shown a
higher efficacy than flossing instructions. In artificial caries lesions adhesives have shown a deeper
penetration when compared to sealants.
Objective: To determine which adhesive: Excite Ivoclar-Vivadent (E), Prime&Bond-NT Dentsply
(PB) and Single-Bond-2 3M-ESPE (SB), achieves in ICDAS proximal lesions type white-spot-onwet-surface (WSL): 1. external capping; 2. higher penetration within the lesion depth.
Materials And Methods: From 420 recently extracted premolar teeth with proximal lesions, one
calibrated examiner in ICDAS criteria (LEL) selected 117 teeth with WSL; 39 were randomly
assigned to each group: -E, -PB, -SB; they were placed on plaster with a 1.2mm space from another
tooth, simulating a temporary approximal separation. The lesions were sealed (OLZ) following the
commercial instructions and the technique used by Martignon et al. [Caries Res 2006;40(5):382-8],
with the previous addition of methyl-blue dye to the adhesives in order to allow for the material to be
seen within the lesion. 250 longitudinal sections were obtained and examined under
stereomicroscopy (SM) using a metal caliper (scale: 50). The Kruskal-Walis test (p<0.05) was used
to establish significant differences between adhesive-groups in depth-penetration percentage.
Results: More than 92% of the lesions were covered and penetrated by the material. The adhesive
that in average penetrated in a higher proportion was E(85%), followed by SB(77.4%) and
PB(71.2%) (p>0.05).
Conclusion: This in vitro study confirms in proximal WSL of natural teeth the penetration of
adhesives in a depth greater than 70% of the lesion.

Abstract
Objective: The purpose of this study was to evaluate after 42 months, through the independent
assessment of bitewing radiographs, the efficacy of sealing early active proximal lesions among
Colombian patients who were sealed in 2003 (Martignon et al., Caries Res 2006; 40(5):382-8).
Methods: The sample size was 33 subjects who finished the reported study. Patients were
contacted by phone and were given an appointment at the Universidad El Bosque for having
standardized bitewing radiographs taken of the control and test lesions, and they were asked how
often they floss per week. A positioning device for bitewing radiographs was used to achieve
radiographic projection geometry.
Results: The final sample corresponded to 23 patients (69.9%). Among the test group, 4 lesions
(17.4%) progressed and among the control group 5 lesions (21.8%), without statistical significant
difference (McNemars test value-p > 0.05). A regular flossing (3 times per week) was reported in
78% of the Colombian sample, against 15% in base line.
Conclusion: Stabilization was found in most of the sealed and non-sealed lesions from 2003,
possibly associated to the increase of participants reporting a current regular use of dental floss.

Abstract
There is no scientific evidence that indicates neither the optimal number of implants nor the
dimensions that are clinically reliable in Implant-supported fixed restorations. The purpose was to
describe by means of a three-dimensional finite element model the behavior of an implant-supported
restoration when subjected to different occlusal loads obtain with a gnathodynameter.
Materials and Methods: In order to determine the optimal number of implants, position, cantilever
length and the behavior of the structure and the implants, a simplified finite element model was
developed to analyze the biomechanical behavior by applying an occlusal force in all dental
positions. Afterwards a three-dimensional detailed finite element model was developed on which the
biomechanical behavior of the restoration was verified with the lower number of implants and a
uniform stress distribution obtained from the simplified model.
Results: A cantilever length of 10 mms is viable for all restorations, while a cantilever length of 20
mms was not viable and 4 implants was the optimal number which distributed efforts with out
surpassing the strength yield of materials.
Conclusions: Three implants did not offer satisfactory results when a load was applied to a
cantilever. A four implant design was found to be optimal with a cantilever length shorter than 15
mms.

Objective: The aim of the present study was to evaluate the effectiveness of three techniques for
catalyze dental bleaching in office; the halogenous light, V-LED and Laser argon and compare them
with the ambulatory dental bleaching technique.
Materials and Methods: This study was carried out in 350 lower incisive bovine teeth, in which
measurements of color were obtained for the cervical, half and incisal thirds of each tooth. Three
catalytic lamps were used, halogenous Ligth (Optilux 501, Demetron®), V-LED (Fast Bleach,
Cambridge®) and Laser argon (Accue Cures 3000, Lasermed®) with two different agents: hydrogen
peroxide to 25% (Zoom®, Dental Discus) and to 35% (Polaoffice®, SDI). The three techniques were
compared with the ambulatory technique, using 10% carbamide peroxide (Opalescence®,
Ultradent). To evaluate changes in color, an espectofotómeter (Ocean Optics®) and the colorimeter
CIELab with the values of ÄE* were used.
The statistical analysis was performed using the student t-test for comparisons between related
samples, the Kruskall-Wallis test for comparisons regarding agents, catalytic lamps and thirds, and
the Mann-whithney test to determine the differences among agents, thirds and catalytic lamps.
Results and conclusion: The results of this study suggest that there are not statistically significant
differences between the dental bleaching technique in office and the ambulatory technique. The
catalytic lamp that showed less effectiveness on the change of color was the Laser argon.

Abstract
This In Vitro study assessed a new resin-modified glass ionomer system (Fuji BOND LC®GC)
compared and analyzed its tensile strength in relation to glass Ionomer (Fuji II® GC) and
conventional resin systems (Z100® 3M). The adhesive system was placed on intermediate coronal
dentine.
It was hypothesized that the use of Fuji BOND LC®, GC would improve the retention of a restoration
made with glass ionomer and conventional resin.
Two hundred and seventy-five extracted third molar were divided into five groups of 55 teeth and
bonded with a restoring material Fuji II LC® GC and Z100® 3M. It was compared the result of
adhesion between conventional adhesion system and the bonding system using the new modified
glass ionomer system, Fuji BOND LC®, GC. Fuji BOND LC® light cured adhesive. The teeth were
debonded by applying a shear load using an Instron universal testing machine.
The mean force to debond was calculated for each group and each tooth was examined to record
the site of bond failure and MPa needed to debond those restorations. Bonding failure was
compared in each group with a 40 per cent fracture rate with the control. The results showed that
the resin-modified system Fuji BOND LC® was very effective at improving retention of restorations
onto intermediate coronal dentine.

Abstract
Healthy ways of life can be implemented in a population of students of the “Fundación Formemos” to
propitiate and to support an acceptable condition of oral health.
The objective was to promote in the school community of the “Fundación Formemos” and in their
families a conscience of oral health, and development of promotional and preventive activities,
obtaining therefore the prevention of oral pathologies.
It is part of the macroproject of extension MODEL OF INTEGRAL ATTENTION IN ORAL HEALTH
FOR COMMUNITIES PLURALETHNIC, UNDERCLASS AND IN HIGH RISK OF POVERTY, which
is developed in the National University of Colombia.
The objective group was the students of fifth a ninth degree of the FF, that they are result from the
forced displacement caused by the social situation of the country, that from small they must assume
rolls of an adult person to develop in useful form in the society.
It realized participate investigation with the application of a model integral attention looking for the
active participation of the population, with regard to their social representations, and the dialogue of
knowledge.
According to the results obtained and compared with the ENSAB III (National study of oral health),
the studied population is in acceptable conditions in tooth decay and oral hygiene. The most relevant
problem that they have is the presence of fluorosis. (Prevalencia of 51 %).
It is important the implementation of programs of prevention of the disease and promotion in oral
health, whose success is obtained devoting these the population at studying and involving to

EVALUATION OF THE ASSOCIATION BETWEEN ORAL CONDITIONS WITH
QUALITY OF LIFE IN THE OLDEST WHOM LIVED IN ELDERLY
INSTITUTION OF BUCARAMANGA: TWO PHASE
Sonia Constanza Concha
Abstract
Objective: The aim was to evaluate the association between the quality of life (QL) with the oral
condition (OC) in the elderly.
Methodology: An analytical cross section observacional study was made. The universe was constituted
by 523 and the sample by 106 people, who lived in three elderly institution of the city, who fulfilled the
inclusion criteria. The variables of the study were social-demographic; systemic condition, the QL, the
OC, the functional physical capacity, mental state, and the social supports. In the analysis, summary
measures were calculated according to the nature of each variable. Analysis of factors was made to
determine the attributes that integrated OC. The exit variable (QL) was related to each other variables by
2 and Fisher´s exact test, the crude OR and intervals of confidence were calculated. Logistic regression
analysis and methods of correction of the OR were applied, the RR were obtained and the goodness of fit
of the model was evaluated.
Results: The quality of life in the elderly registered an average of 49.9±18.6 with rank between 14 and
85. The COP index, the salivary flow and the oral pain were attributes that defined the oral condition; the
67.9% of the population had a bad oral condition. A potential association between bad OC with bad QL of
the elderly wasn't seen RR 0.99 (IC95% 0.38-2.0).
Conclusion: A bad CO does not seem to be associate with bad a CV in the elderly; these results seem to
indicate the little effect that has a bad oral condition, frequent condition in the evaluated population,
relation could be affected by cultural aspects that do that the society in general and the greater adult in
individual, can get to underestimate this condition

Cuartas Luisa, Espinosa Alexander, Carvajal Wilson, Moncayo, Carmen, Bonilla
Jorge
Abstract
Objective: To evaluate skeletal and dental changes in individuals through lateral cephalograms
obtained only after the use of the splint-type Herbst appliances in Class II division 1 malocclusions.
Methods: Several electronic databases (Medline, Pubmed, Embase, Best Evidence and Sciences
Direct) were scrutinized . Abstracts that appeared to fulfill the initial selection criteria were selected
by consensus. The original articles were then retrieved.
Their references were also hand-searched for possible missing articles. Clinical trials that
assessed, through lateral cephalograms with modified Pancherz's analysis, immediate skeletal and
dental changes with the use of Herbst appliances without any concurrent orthodontic appliances,
surgical intervention, or syndromic characteristics were considered. A comparable untreated Class II
division 1 malocclusion control group .
Results: Five articles were finally selected and analyzed. An individual analysis of these articles was
made and some methodological flaws were identified. All the selected studies showed statistically
significant changes in the anteroposterior length of the mandible, mandibular incisor proclination,
mesial movement of the lower molars, and distal movement of the upper molars. Posttreatment
relapse in overjet and molar relationship was also observed.
Conclusions: Dental changes are as important as skeletal changes to attain the final occlusal
results. Long-term, prospective, double-blinded, randomized clinical trials are needed to support
these conclusions.

Abstract
Purpose: Determining the impact generated through a sensibilitation and motivational program
about oral hygiene habits in a scholar group, age range from six to fifteen years old.
Material and methods: A grouping random selection was performed. An intervention group
(n=40) and a control group were assigned (n=45). For the oral health sensibilization two programs
were executed for 4 months. The dependent (The simplified oral hygiene index IHOS and the
gingival index IG), the independent (intervention, brushing, flossing, age and gender) and the
confusion (mother's educational level, provenience and diet) variables were considered.
Results: The participants' average age was 11.2 +2.3 years and the brushing frecuency was 2.9 +
0.4 a day, at the start of the study. When analyzing the sociodemographic variables and the
intervention type, a statiscally significant association was observed in the mother's educational
level, 27.6% (8) from the intervined group and 72.4% (21) from the control group have primary
degree (p=0.01). When evaluating the oral hygiene a statiscally significant and third record,
p=0.004 and p<0.001, respectively. When evaluating the gingival index, a statiscally significant
association was evident in the three records p= 0.010 and p<0.0001, respectively. The quantitative
analysis showed statiscally significant differences in the oral hygiene and gingival index.
Conclusions: The impact generated through the program was positive and it mirrors on the oral
hygiene and the periodontal condition

Universidad de Antioquia. Facultad de Odontología
Abstract
The purpose of this study was to describe the perception of people with HIV about the dental
treatment they receive.
A fenomoligic qualitative research approach based on six categories of analysis was used made: 1)
Importance of dental treatment; 2) Discrimination by the dentists 3) Dentists´ fear to be infected; 4)
Dentists´ knowledge about HIV/AIDS; 5) Dentists´ risk to be infected during the treatment; 6)
Biosafety.
Two people were interviewed using both non-structured and in-depth interviews and four people
were interviewed over the phone. The data was processed by selecting six categories of analysis
and evidence given by the interviewees. Simultaneously, a literature search was conducted in order
to corroborate or refute the importance of the evidence obtained from the testimonies of patients with
HIV/AIDS who seek detal treatment.
It was concluded that dental treatment is refused to patients with HIV/AIDS on the basis of dentists'
fear of infection. Although the interviewees agreed that biosafety techniques should be used by
dentists, however, they feel that there are wrong ideas or lack of understanding about the true means
of disease transmission and the probability of becoming infected during the treatment.
People´s perception can be an important tool to understand the dentist-patient relationship and
dentists´ behavior and attitudes toward patients with HIV/AIDS, in order to find solutions that
contribute to the improvement of health services for these patients.

Abstract
The investigation has a quantitative component which gives count of the state of the health of the
mouth of students in Medellín and of a qualitative component which has a comprehensive
approximation to the meanings, experiences, and practices of the health of the mouth illness
surroundings. This investigation was done with 120 boys and girls between the ages of 12 and 13.
They share a space with certain common characteristics which they can identify with, but not only
their physical dimension, but also with a symbolic and social dimension. In addition, they are
enrolled in twelve public institutions.
The qualitative dimension is done from a hermeneutical perspective, based upon the interpretation
of constructed social texts, which reflect the conceptions that children have upon practices and
experiences in the health of the mouth illness and its meanings from where they have constructed.
Recollection technique and construction of data were done by in depth interviews and recounts.
Analyzing the reduced conception of the process of health illness, the association of the mouth to
stereotype concepts of beauty, the visit to a dentist associated with pain and anxiety, the application
of a technical know-how which hides the child, the lack of knowledge of basic concepts which affect
practices, such as been a part of study findings, one may conclude that it is important to articulate
educational and health sectors in function of creating educational environments which go beyond
the instrumental part with respect to the health of the mouth. On the other hand, it is necessary to
convert going the dentist into an experience which visualizes children, and it should make children
aware and committed of taking care of their mouth on their own.

Abstract
ABSTRACT: Pregnant women, and specially those that are in poverty situations, are considered a
vulnerable group that require integral health attention. Pregnancy courses are oriented in
promoting health and preventing medical sickness not including education with regard to oral
health. The aim of this study was to design, implement and evaluate a programme to complement
pregnancy courses to reduce the risk of early childhood caries and periodontal diseases in the
mothers and their offspring. During the 1st and 2nd semester of 2006, 21 pregnant women, from
the Diana Turbay Health Center, between the ages of 15 and 35 years old were intentionally
selected and given a questionnaire before and after the Oral Health Programme. The presence of
dental plaque was examined by applying the O'Leary Index to evaluate the risk. The data was
analyzed using Excel and a descriptive analysis. The obtained results show that an Oral Heath
Programme increases knowledge concerning oral health and significantly reduces de presence of
bacterial plaque in a group of pregnant women. In conclusion, an Oral health Programme focused
on educating pregnant women is effective to reduce the risk of oral diseases during their pregnancy
motivating mothers in good health habits to prevent early childhood caries in their offspring.

HEALTH SOCIAL REPRESENTATIONS GUIDING THE LIFE EXPERIENCE
OF SOME YOUTH GROUPS IN THE CITY OF MANIZALES, COLOMBIA
María del Carmen Vergara Quintero
Autonoma University of Manizales
Abstract
Through this research work, I try to aim at contributing with some bases that may be of help in
finding a guiding thread between the formulation of policies and the needs, interests and
expectations of the population. Youth, whom are often visualized from our perspective of adults, are
perceived as risk people, with a high degree of vulnerability towards sexually transmitted diseases,
adolescence pregnancies, a certain tendency to the consumption of psychoactive drugs and a
terrifying nearness to violence. The policies formulated by adults correspond more to their fears and
knowledge than to the needs undergone by the young people themselves.
Accordingly, I have decided to approach the problem through the youth social representations with
reference to health in order to define proposals that will contribute to generating a major impact in
their health in the city of Manizales, Colombia. The concern generated by this research results from
the conviction that it is necessary to listen to young people to have a holistic vision of their problems
and their requirements to be taken into account.
The most significant results from this project allow us to understand that social representations that
guide youth life experience with reference to health result from a wide perspective about the world;
thus, defining health as a balance state between mental, material, spiritual, emotional and moral
aspects with a social projection. Work is one of the activities that youth consider healthful, as well as
one of the requirements to have good health, as work generates freedom and autonomy. Health
deals with violence, human rights and with peace. “Health is to the individual as peace is to the
collectivity”.
