Recommended by the American Academy of Craniofacial Pain (AACP), the leading
organization of practicing TMJ clinician specialists.
The TMJ ScaleTM Patient Self-Test is the only test currently available that can do all of the following:
1. Indicate if you have a TMJ disorder with extremely high accuracy (scientific publications)
2. Compare the Severity of your disorder to others with a similar problem
3. Identify which physical symptoms (Pain, Jaw Joint Dysfunction and Limitation of Jaw
Movement) are Clinically Elevated
4. Compare the severity of your Physical Symptoms to others with a similar problem
5. Indicate if another, Non-TMJ, problem is present
6. Indicate if your level of Emotional Distress is clinically elevated
7. Indicate if your Stress level is clinically elevated
8. Indicate if your problem may become or already is a Chronic, i.e. long term, problem
9. Be used to determine if your problem is getting better, worse or unchanging over time
10. Indicate if an evaluation by a TMJ Specialist is indicated
11. Provide all the above inexpensively, confidentially and in the privacy of your own home
The TMJ ScaleTM is a sophisticated diagnostic test. It collects information about physical symptoms and then analyzes this information to determine if the probability of a TMJ disorder is high. The TMJ ScaleTM falls into the category of diagnostic tools called "psychometric tests." This type of testing instrument has a long history of use going back over 100 years. The scientific principals on which these tools are developed have evolved to a very high degree and this type of testing is presently used in medicine, dentistry and psychology.
How It Works
The TMJ ScaleTM collects a comprehensive inventory of key symptoms related to TMJ disorders. It does this by asking the test taker to provide information about the presence and absence of a wide variety of physical symptoms in the areas of:
- Pain in the jaw joints and surrounding muscles of the face, head and neck
- Problems of the teeth not fitting properly or the bite feeling off, uncomfortable or changing
- Noises and sounds coming from the jaw joint, like clicking, popping or grinding
- Problems opening and closing the jaw and mouth, such as locking or sideways deviation
- Limitations in moving the jaw through a full range of motion, both opening and sideways

The symptoms are grouped into several categories, or Scales, and the scores for each Scale are calculated. The resulting Scale Scores are then compared to extensive, well established and scientifically validated databases from thousands of other persons with TMJ disorders. These scores and comparisons are used to generate the TMJ Scale Report-Patient VersionTM.

The TMJ Scale is one of the most widely studied and thoroughly researched tests of its kind in the field of TMJ diagnosis. Many of the most respected TMJ researchers and clinicians from across the U.S. and Canada studied literally thousands of patients over many years to help ensure the highest possible accuracy and usefulness of the TMJ Scale. Tens of thousands of patients have been subsequently studied and hundreds of thousands of patients have been tested in clinical settings in Universities, Hospitals and Private Practices specializing in TMJ diagnosis and treament.
The extensive Scientific Research programs needed to create this unique TMJ testing tool and to continue to define and demonstrate its accuracy and usefulness have taken more than a quarter century. These scientific research studies have been published in many of the most prestigous Scientific and Clinical journals in the TMJ field. Included in these publications are studies of the development, validation, accuracy, reliability and effectiveness of the TMJ ScaleTM. An accuracy of about 88-93% has been repeatedly reported in various settings. In some cases the accuracy can be even higher and the predictive value of this test has been carefully documented. The TMJ Scale-Patient Self Test is designed for those 13 years and older and can be taken in a very short amount of time, usually about 15-20 minutes.
The following are some important things to know about the TMJ ScaleTM:
- The test has been studied on persons 13 years of age and older. It is therefore not recommended for those below the age of 13.
- If you are under the age of 18 years, it is recommended that you have a parent or other responsible adult supervise your taking this evaluation, and help you both understand the results and make any subsequent decisions regarding seeking out professional help and possible treatment.
- The TMJ Scale ReportTM does not indicate your name or identify who you are. Therefore, the test results are confidential.
- It is important to answer all questions as accurately and honestly as possible in order that the test results be reliable. Please read each question carefully so that you understand its meaning. To see sample questions, which you can answer, please click on Sample Questions.
- You will be asked to indicate whether you are male or female. Research has shown that the most accurate results are obtained by comparing your scores to TMJ patients of the same sex. Therefore, if you do not indicate your sex, the test cannot be taken.
- You will be asked a few other questions regarding your age, marital status, education, race and length of time you have been having problems. The answers to these questions are optional and your test will be scored whether or not you supply this information. Please note that your TMJ Scale ReportTM will not contain this information. This information will be very valuable in our ongoing research and studies in trying to understand who has "TMJ" and what factors might be involved.
- The amount of time needed to complete the TMJ ScaleTM evaluation varies but is often around 15-20 minutes.
- It is strongly recommended that you complete the test and save/print your Report in one sitting. However, you will be able to assign yourself a User Name and Password to log back in to your test in case you do not complete the test right away. However, once you generate your Report you will immediately save and print it at that time because your test answers and Report will be permanently removed from the website after 10 days and you will no longer be able to access your answers or Report after that time.
- The cost of taking the TMJ ScaleTM is far below the usual fees charged by most dentists who use the TMJ ScaleTM as part of their evaluation. The reason for this is that the dentist receives a much more comprehensive and complex TMJ Scale ReportTM, that requires skill, training and considerable time for interpretation and application of the results.
- Even if the TMJ ScaleTM results do not indicate the presence of a disorder, it is always advisable to seek out professional help if you have symptoms, worries or concerns about a problem you are experiencing.
- Although the TMJ ScaleTM is a highly accurate and reliable assessment tool, no diagnostic test is 100% accurate. It is being used here only as a screen for the presence of a TMJ disorder. It cannot replace a thorough and comprehensive evaluation by a dentist or specialist in this area.
- The statements contained within the TMJ Scale ReportTM are based on statistical probabilities and therefore are suggestive rather than conclusive. No decisions or actions should be based solely on the results of this test.
- You will agree to be soley responsible for the use of any information obtained from this test or from this website and that neither Pain Resource Center, Inc. nor any of its officers, board of directors, owners or employees are responsible, or have any liability, to the test taker or anyone else for any decisions made or actions taken based on the results of this test or information from this website.
