TMJ Imaging:
What Should be the Standard of Care?
By: Dr. Francisco Eraso
Standard of care:
“ … watchfulness, attention, caution and prudence
that a reasonable person in the circumstances would
exercise …”
The problem is that the “standard” is often a subjective
issue upon which reasonable people can differ, however, a standard of care holds a person of exceptional
skill or knowledge to a duty of acting.
This brief descriptive paper is not trying to define by any means
the standard of TMJ imaging. The goal of this article is to
review some concepts for determining what is more appropriate in TMJ diagnosis using imaging as a diagnostic tool.
Knowledge of the anatomy of the TMJ is an extremely important component of the diagnostic process, it will help us to determine which imaging technique is the most appropriate in the
diagnosis of temporomandibular disorders (TMD). The anatomic components of the TMJ are osseous, soft tissues and
other structures (i.e. joint compartments).

President's Message
It is a privilege to be a part of this great organization, and I look forward to my final year on the
Board with both excitement for what is yet to be, and certainly a little anxiety about fulfilling my
commitment to you as your President. I will do my best in AADMRT’s strive for excellence in
service and education for its members, and I know this can happen with the help of terrific Board
members. I was so pleased at our last Board meeting to be a part of this caring, motivated and
dedicated group. And where would we be without the work of Merry as our secretary and Claudette
as our treasurer! Thank you all!
To follow in the footsteps of past president Craig Dial makes me understand how it must feel to be
next in line to skate after Michelle Qwan or Sasha Cohen! Craig has been an inspiration that has
made me want to do more than I thought I could for our organization. He has helped our organization build into what we are today - an awesome resource for our educational needs and goals. I
Jeannie Herriott
would like to thank Craig for his years of unselfish commitment, and to show where our organization has been and where it is going with some of my favorite messages from Craig over the years:
“...We, as an organization also need to continue to
stay updated in areas like computer technology, xray equipment, continuing education, and technical aspects. Our group has mega horsepower to get
the job done, plenty of torque to go forward with
new ideas, and you can be reassured your organization will take care of you, just like you have taken
care of it over all these years.”
“The AADMRT organization is also an
investment...Let’s look into what the AADMRT does
for our dollar. First off, our group offers continuing education courses twice a year. We also have a
tremendous resource through this quarterly newsletter. Another valuable piece of being a member
is our web site...The AADMRT is also advertising
your lab for you.”
Lastly, a quote printed in 2003 but appropriate today:
“This organization is based on volunteers to function. Without the people to come forward and volunteer, we would not have an organization. I am
proud of our entire group, and the fact that we as
an organization can step up, help out, and happily
assist when needed.”
I am also proud of our organization, and with the help
of the Board and other volunteers, we will continue to
get better and better.

Editor's View
Everyday we are faced with obstacles. Most of these obstacles are minor glitches that
keep our day from running as smoothly, and peacefully, as we would like. How about
when we finish writing the long and detailed email message and when we press send it gets
lost in never-land and we must begin again. Or when we turn off on our exit only to find
traffic backed up and we are already running late, or the coffee filter falls in and ruins the
fresh pot of coffee, and we have to start all over, these situations tend to make us feel
stressed and anxious. But these events are daily episodes that should not raise our heart
rate if we can just take them in stride and make the best of the situation. We cannot control
these daily-annoying obstacles; the only thing we can control is how they make us feel, and
how they change our disposition for that time and perhaps the rest of the day. I think the
Master Yogi’s really are on to something with the deep cleansing breath. At these critical
stressful moments, stop and take a deep breath in and out and let it go...

MOUNTS & SUPPLIES
There was about 4 feet of water in the parking lot and 6 inches of water in our building. We lost about half of our
inventory. Fortunately our manufacturing equipment was not damaged. When the water receded our offices were
covered with silt/mud which has amazing properties;
it is so slippery you are surprised to be on your rear in
the mud in an instant; it is of microscopic fineness that
is very heavy and dries to a plastic-like hardness. It
required two power-washer treatments and a supercharged wet vacuum to restore our floors. Replacing
our inventory and cleaning our inventory space has
been a challenge. We want to thank our loyal customers for understanding and continuing to support us.

California Report
Submitted By: Matt Kroona
The California Radiologic Technology Certification Committee (RTCC) met on Thursday,
Dec 15 in Sacramento. The agenda consisted of one topic: Training Requirements for the
Operation of Computed Radiography (CR/DR) Equipment. The purpose of the meeting
was to discuss Title 17, Section 30447 (a) (6), which restricts limited permit holders from
using digital radiology equipment. It was clear from the discussion that there is a serious
power struggle going on between the “haves” (CRTs) and the “have-nots” (LPs). CRTs currently are not required to have any training in the proper use of CR/DR equipment. They feel that their education makes them
inherently capable of using digital equipment properly. LPs on the other hand are too stupid (my summary of their
carefully selected words) and can’t be trusted or even trained to properly and safely expose patients using complicated computer technology. I couldn’t decide if I should laugh or cry at their backward reasoning. No decision was
made at the meeting and the discussion will continue at the next RTCC meeting scheduled for Feb. 22 in Burbank.
The good news is that as Dental Limited Permits, we are exempt from the restriction on using digital radiographic
equipment. The bad news is that there is a class war brewing in California and unfortunately, we are members of the
“under” class. My hope is that we will blur these lines of class by continuing to do everything in our power to
give the dental and medical community every reason to respect us, to look up to us for our expertise, and to admire
us for the excellence we bring to this ever changing field.

Standard continued from page 1
The mandibular condyle is convex along the surface that receives the force, wider in the medio–lateral
dimension, and has an oval shape antero–posteriorly. This observation and others, such as the relation of
the articular disc with the condyle and the temporal bone, muscle attachments, and occlusion, requires a
3-D approach to analyze the TMJ complex. Sagittal and coronal sections in the imaging of the TMJ are
needed to fulfill this requirement. (Figure 2)
In the diagnostic process it is important to differentiate
two concepts: differential diagnosis and diagnosis. The
first concept refers to the possibilities based on the
patient’s signs and symptoms while the diagnosis refers
to the art of distinguishing one or more entities from
others. For this to happen we need to use diagnostic
aids, which are instruments or procedures that expedite
the diagnostic process (i.e. imaging). These diagnostic
aids should be reliable and valid. The diagnostic validity
of imaging techniques had been measured in the literaFigure 2: Sagittal and coronal cuts needed in the 3-D
ture using concepts such as sensitivity (ability to diagassessment of the TMJ
nose correctly a condition that actually exists) and specificity (ability to diagnose a condition that actually does
NOT exist (false positive) in relation to a “gold standard” (the best instrument, procedure, finding or
criteria to recognize a disorder or pathology).
As mentioned before, hard tissues, soft tissues or a combination of both TMJ’s structures can be seen in
an image. For hard tissue assessment (i.e. bone changes, condylar position) the following common
imaging techniques can be considered:
·
·
·
·
·
Transcranials
Panoramics
Extraorals (lateral, posterior-anterior, SMV views, etc)
Tomography
Computed tomography/Cone Beam Computed Tomography (CT – CBCT).
Transcranial images are good for condylar translation assessment and have been used as a “screening”
tool for osseous changes in the lateral 1/3 of the articulation, however, because of projection geometry
the articular space can be distorted. The validity of the transcranial x-ray for the assessment of a diagnostic task such as rheumatoid arthritis using tomography as the “gold standard” is good (sensitivity
79% - specificity 96%). 1
When studies used panoramic imaging (Figure 3) for the same diagnostic task using the same “gold
standard”, results were as good or better than the transcranial images (sensitivity 81% – specificity
100%).1 But, a question for these studies should be: is tomography the “gold standard”?
Standard continued on page 17

Standard continued from page 15
Figure 3: Bone changes of the condyle found in panoramic images
Submental-vertical (SMV) views help us to minimize technical errors aligning the X-ray beam relative to the condylar
axis in the horizontal plane. Ideally, it must be used in combination with other images (tomography) for optimal
diagnostic results.
Tomography on the other hand has been considered as one of the best diagnostic aids for the evaluation of the articular
spaces, it is optimal in the detection of bone lesions, especially when frontal and sagittal views are taken in combination. Studies using this technique for the detection of osseous defects showed inferior results compared to previous
studies (sensitivity 61% - specificity 73%), however, using direct visual exams of autopsy specimens as a “gold
standard”.2
Computed tomography (CT) is an excellent diagnostic tool that overcomes most of the problems with the techniques
previously described: it offers excellent resolution and is effective for the diagnosis of tumors. Even though it is a tool
that easily allows 3-D assessment of the TMJ complex, it is not useful for the visualization of soft tissue and requires
high levels of radiation. Also, high cost and limited availability are some of its main disadvantages. When reports in the
literature used CT for the detection of osseous defects employing tomography as the “gold standard”, results were
excellent (sensitivity 100% – specificity 94%).3 When direct visual exams of autopsy specimens were used as a “gold
standard”, results were also very good (sensitivity 75% – specificity 94%).4
Cone beam computed tomography (CBCT) differs from CT in the type of source detector complex and in the method
of data acquisition. Because, CBCT presently uses one rotation around the patient similar to the panoramic radiography, a complete dento-maxillofacial volume or limited area of interest (i.e. TMJ) can be obtained.5 As far as radiation
dose, CBCT is much lower when compared to CT and comparable to a series of dental radiographs when we
balanced diagnostic potential, risks and cost. (Table 1) 6

Multi slice scanner (* Siemens Sensation 64, 120 kV, effective tube current 80mAs, slice thickness 0.75mm & ** Newtom QR DVT
9000, 110 kV, tube current 2.5 mA)
Taking into account all of the advantages of the
CBCT to image the TMJ complex, CBCT provides the opportunity to evaluate several areas of
interest (i.e. sinuses, airways, etc.). This 3-D approach is a powerful tool for diagnosis, planning,
monitoring and evaluation of TMD. (Figure 4)
For soft tissue assessment (i.e. disc position) the
following most common imaging techniques can
be considered:
·Arthrography
·Magnetic resonance imaging (MRI)
Arthrography was a technique described in the
past to demonstrate its potential value in the diagnosis of soft tissue derangement of the joint. However, it had few advocates, and the technique itself for the TMJ had only limited clinical use. The
reasons for the skeptical attitude toward this
Figure 4: CBCT TMJ study
method is attributed to at least 3 disadvantages:
(Courtesy: Dr. David Hatcher – DDI Imaging Center, Roseville, CA).
1) difficulty of injecting into the joint compartment,
2) pain for the patient, 3) information gained at
the early stage of its development was usually of limited value for treatment planning and evaluation of prognosis.7
MRI does not use ionizing radiation, making this technique possible to distinguish between soft and hard tissue. It
provides excellent images of disc displacement (DD) in multiple planes. However, problems such as cost, availability
and claustrophobia need to be taken into consideration. It is important to recognize that MRI results should not dictate
the treatment; clinical signs and examinations are more important. MRI is not a routine procedure for most patients. It
is indicated when something other than disc displacement (i.e. tumors), prior to intracapsular surgery or when conservative treatment options are not effective. The validity of MRI images for the detection of DD (sagittal & frontal views)
using direct visual exams of autopsy specimens as a “gold standard” showed very promising results (sensitivity 86% &
87% – specificity 63% & 80% respectively).8,9 (Figure 5)
18
SUMMARY:
A complete assessment of the TMJ requires the knowledge of its components. Panoramic radiographs had been demonstrated to be an excellent
screening tool. If tomography is being used to evaluate the osseous components of the TMJ, SMV views should be taken to correct the X-ray beam in
relation to the condylar axis at the horizontal plane.
It is clear that 3-D imaging has becoming an essential tool in dentistry. The
development of spiral CT, CBCT and MRI has revolutionized the way that
we evaluate the TMJ complex. Three dimensional analysis is a powerful tool
for planning, monitoring and evaluating the TMJ; however, the accuracy and
reliability depends on the correct application of the images obtained. CT
Figure 5: MRI evaluation (sagittal &
images are documented in the literature to be the image of choice for hard
4
frontal
views) for an orthodontic patient
tissue assessment, however, radiation dose, cost and availability are a conscreened using a panoramic radiograph
cern. CBCT is an excellent choice for a complete 3-D TMJ assessment; however, further studies are needed to confirm its diagnostic validity. MRI definitely is the standard of care for soft tissue assessment; however, it is important to recognize that MRI results should not
dictate the treatment. Clinical signs and examinations are not replaced by MRI.
Finally, the ability to interpret the information obtained is proportional to familiarity with the structures and imaging
technique. The proper interpretation of images by an oral and maxillofacial radiologist is as important as the images
themselves. This approach will enhance treatment planning and its proper clinical application.

PRESS RELEASE November 22, 2005
The University of Maryland chose Planmeca to build a digital clinical environment for dental
education
The Finnish dental equipment manufacturer Planmeca Oy has signed a major equipment delivery
agreement with the University of Maryland. Planmeca will supply the Baltimore College of Dental
Surgery (BCDS) with 324 dental units including integrated software and digital imaging equipment
for educational and clinical use. This agreement is the largest delivery agreement in the history of
Planmeca and worth nearly 10 million U.S. dollars.
In co-operation with Planmeca USA, Inc. Planmeca Oy will supply the Baltimore College of Dental
Surgery with 324 digital dental units and patient chairs, 79 digital intraoral X-ray units, as well as digital
panoramic X-rays. In addition, Planmeca’s Canadian subsidiary, Triangle Furniture Systems, Inc. will
supply the university with all the operatory dental cabinets. This equipment will be delivered and installed
by July 1, 2006.
This project is Planmeca’s second major university delivery to North America this year. Earlier this year
Planmeca supplied the Canadian University of British Columbia’s Faculty of Dentistry, in Vancouver,
with 144 dental units including integrated software and digital imaging equipment.
”Planmeca is the only manufacturer in the industry who can offer integrated equipment and software
solutions for specific needs of dental education and large university clinics. Our software and the digital
platform of the dental units enable remote monitoring and management of the units. Moreover, this
integrated system provides means for modern, factbased interactive tutoring and centralized advisory system, which is highly beneficial and cost-efficient in
large clinics”, says Mr. Tuomas Lokki, Vice President,
Marketing and Sales.
The BCDS will be the most modern dental school in
the U.S. “This generation of students expects education that is integrated into technology. In addition, they
want to have fun at the workplace and at studies and
they are looking for an opportunity to learn at their
own pace.
22
This is possible in the IT-friendly environment. Our students deserve the best possible hardware and
software as well as a learning environment where information is available on-demand”, explains Dr.
Christian Stohler, Dean of the BCDS.
The U.S. market expects extensive quality assurance regulations such as HIPAA standards for improved
patient safety in oral health care. All dental unit field data, digital treatment documentation as well as
patient information, intraoral, extraoral X-rays, and intraoral camera images are automatically stored in
the database for scientific research and educational purposes. “Ultimately, this data will create a backbone for artificial intelligence to be used in tutoring. The challenge is to change the entire concept of
dental education including new equipment, new curriculum and new way of thinking. Planmeca’s solution
is flexible enough to fullfill these requirements”, says Dr. Stohler.
“This is a significant project for us, because it is the first major university delivery to the U.S. However,
this year has strongly indicated that the North American market is looking toward Planmeca’s technologically advanced dental units for the future. The region has traditionally been strong grounds for our
radiology equipment. Planmeca has a market share of approximately 30% of dental radiology equipment
in the U.S.”, says Mr. Lokki.
