Wear Face Masks with No Metal During MRI Exams: FDA Safety Communication

The FDA recently received a report that a patient’s face was burned from the metal in a face mask worn during an MRI. The FDA reminds patients and providers that patients should not wear any metal during an MRI. TOPIC: Wear Face Masks with No Metal During MRI Exams: FDA Safety Communication  

A Tribute to William “Bill” Maixner, Ph.D., D.D.S

All of us at The TMJ Association are deeply saddened by the loss of a treasured friend, an accomplished and highly respected scientist, empathic clinician and one of temporomandibular disorder's (TMJ) greatest champions – Dr. William “Bill” Maixner. Bill passed away on Monday, November 2, 2020, at the age of 68.

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.

The Latest In Science on Biofeedback

Efficacy of biofeedback-based treatments for temporomandibular disorders.
Crider A, Glaros AG, Gevirtz RN.
Appl Psychophysiol Biofeedback. 2005 Dec;30(4):333-45.
Bibliographic searches identified 14 controlled and uncontrolled outcome evaluations of biofeedback-based treatments for temporomandibular disorders published since 1978. This literature includes two randomized controlled trials (RCTs) of each of three types of biofeedback treatment: (1) surface electromyographic (SEMG) training of the masticatory muscles, (2) SEMG training combined with adjunctive cognitive-behavioral therapy (CBT) techniques, and (3) biofeedback-assisted relaxation training (BART). A detailed review of these six RCTs, supplemented with information from non-RCT findings, was conducted to determine the extent to which each type of intervention met treatment efficacy criteria promulgated by the Association for Applied Psychophysiology and Biofeedback (AAPB). We conclude that SEMG training with adjunctive CBT is an
efficacious treatment for temporomandibular disorders and that both SEMG training as the sole intervention and BART are probably efficacious treatments. We discuss guidelines for designing and reporting research in this area and suggest possible directions for future studies.

A meta-analysis of EMG biofeedback treatment of temporomandibular disorders.
Crider AB, Glaros AG. J Orofac Pain. 1999 Winter;13(1):29-37.
AIMS: Outcome evaluations of treatments incorporating electromyographic (EMG) biofeedback for temporomandibular disorders (TMD) have been conducted for more than 2 decades. The purpose of this study was to review the available literature to determine the efficacy of biofeedback-based treatments and to estimate treatment effect sizes. METHODS: A literature search located 13 studies of EMG biofeedback treatment for TMD, including 6 controlled, 4 comparative treatment, and 3 uncontrolled trials. Three types of outcome were examined: patient pain reports, clinical exam findings, and ratings of global improvement. RESULTS: Five of the 6 controlled trials found EMG biofeedback treatments to be superior to no treatment or psychologic placebo controls for at least 1 of the 3 types of outcome. Data from 12 studies contributed to a meta-analysis that compared pre- to posttreatment effect sizes for EMG biofeedback treatments to effect sizes for control conditions. Mean effect sizes for both reported pain and clinical exam outcomes were substantially larger for biofeedback treatments than for control conditions. In addition, 69% of patients who received EMG biofeedback treatments were rated as symptom-free or significantly improved, compared with 35% of patients treated with a variety of placebo interventions. Follow-up outcomes for EMG biofeedback treatments showed no deterioration from posttreatment levels.
