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.

Corticosteroid Injections - Buyer Beware

  • Jul 10, 2019

Corticosteroid injections have been used to reduce pain and improve function of arthritic joints in various parts of the body.  What about the temporomandibular joint? 
Not so fast, say the editors of a review article examining the evidence on steroid use to treat temporomandibular disorders (TMD). There been no well-controlled randomized clinical trials with long-term follow-up, but  only small studies with no controls and “information presented … based on perception and opinion.”  
This does not mean that steroids should never be used. But specific guidelines are simply not available. There has been no assessment of the various formulations of steroid available, the dosages, and variations in injection techniques. Further complicating steroid treatment in the jaw is the fact that there is no one cause of jaw pain and dysfunction; and certainly not every TMD patient has degenerative joint disease.  Moreover, there are risks with steroid injections, with the potential for damage to cartilage and fibrous tissue.  All told, The TMJ Association agrees with the conclusion of the article: “There is just too little science evaluating short and long term efficacy.” 
In a few selected instances, some conditions (such as juvenile rheumatoid arthritis of the jaw and TM joint arthralgia) associated with acute inflammation and osteoarthritis, may find relief via steroid injections, but even here repeated injections are not recommended.
