New Report on Temporomandibular Disorders: Priorities for Research and Care

Over a year and half ago, the National Academy of Medicine (NAM) began the most comprehensive study ever undertaken on Temporomandibular Disorders (TMD). The study assessed the current state of TMD research, education and training, the safety and efficacy of clinical treatments, and associated burden and costs.

Statement by NIDCR Acting Director on the National Academies of Sciences, Engineering, and Medicine Report on Temporomandibular Joint Disorders

I am pleased to announce the release of the National Academies of Sciences, Engineering, and Medicine (NASEM) report, Temporomandibular Disorders: Priorities for Research and Care. As underscored by the comprehensive report, temporomandibular joint disorders (TMJDs) are a diverse and still poorly understood set of complex, painful conditions affecting the jaw muscles and tissues, temporomandibular joints, and associated nerves. Clearly, there is much more to be understood, and these conditions continue to confound medical and dental health care providers and researchers.

Have you seen the film Dark Waters?

The Film. Dark Waters is about attorney Robert Billott's real-life 20 year legal battle against DuPont chemical for releasing toxic waste - perfluorooctanoic acid, or PFOA - into Parkersburg, West Virginia's water supply, with devastating health effects on the townspeople and livestock. PFOA, also known as C8, is a man-made chemical. It is used in the process of making Teflon and similar chemicals known as fluorotelomers.

Drug Induced Bruxism

The authors of this article state that orofacial movement disorders (bruxism) are treated typically by dental professionals and not by those specialists (neurologists) researching and treating the other movement disorders (Parkinson's disease, Huntington's disease, tremors, etc.). Again, this is more evidence of the complexity of TMD and the need for multidisciplinary research and treatment in TMD.

Are There Any Good Treatments for Jaw Arthritis?

Better Quality Studies Needed

When it comes to guidance for making health care decisions the Cochrane Collaboration is an outstanding authority. The Collaboration is an international organization that aims to provide the highest quality evidence-based information to healthcare professionals and the public. Cochrane experts conduct systematic reviews of the scientific literature on a given topic by compiling, evaluating and summarizing research results. One recent review, " Interventions for treating osteoarthritis in the temporomandibular joint," is of particular interest to TMD patients.

Researchers from Cochrane’s Oral Health Group looked at available therapies to manage osteoarthritis (OA) of the TMJ, the most common form of arthritis affecting the jaw. Current treatments range from non-surgical options such as prescription drugs, warm or cold packs, occlusal splints, irrigation, and steroid injections, to surgical joint repair or replacement.

Unfortunately, the team found only three clinical treatment trials out of 460 published studies that met the rigorous criteria Cochrane employs. The trials measured a range of patient outcomes as a result of treatment, including reductions in pain and jaw sounds, improved jaw movements, overall quality of life and patient satisfaction. The authors found “weak evidence” showing that injections of sodium hyaluronate and betamethasone were equally effective in reducing pain and discomfort, as were the dietary supplement glucosamine compared with ibuprofen. Pain was similarly reduced in patients using occlusal devices compared to diclofenac sodium (an anti-inflammatory drug). In the conclusion, the researchers argued for better studies and a wider range of interventions for jaw osteoarthritis. They were also concerned that too many studies had mixed groups of patients: individuals with osteoarthritis, but also other TMJ disorders.
