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.

TMJ Disorders and Dizziness

New Research Links to TMJ Inflammation

TMD patients sometimes report feeling dizzy or experiencing an uncomfortable whirling sensation throughout their bodies, either of which can place them in danger of losing their balance and falling. There are sensors in your inner ear that monitor your body’s position in space and response to gravity by sending nerve signals to brain centers called the vestibular nuclei. In turn, nerve cells in these centers send signals to your eye and limb muscles to make appropriate adjustments to keep you upright and balanced. This all happens unconsciously, by way of reflexes. So how could having TMD interfere with this process?

A team of Korean researchers decided to see if the vestibular nuclei were affected in cases of jaw inflammation by means of simulating TMD in animal models. The team used two groups of rats. One group was injected with an inflammatory agent in the right TMJ. The other was a control group injected in the right TMJ with normal saline. They waited 24 hours and then studied neural activity in the vestibular nuclei. Sure enough, they noted signs of increased activity in the vestibular nuclei on both sides in both the experimental and control groups, but much greater activity in the nuclei of the experimental animals on the inflamed jaw side provide grounds for suspecting that symptoms of dizziness might well reflect abnormal vestibular activity as a result of TMJ inflammation.
