Metal Implants and Dental Amalgam: The FDA Announces Public Meeting and Paper

The U.S. Food and Drug Administration (FDA) announced a paper on metal-containing implants and a panel meeting as part of ongoing efforts to evaluate materials in medical devices to address potential safety questions.

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.

Cervical Muscle Tenderness in Temporomandibular Disorders and Its Associations with Diagnosis, Disease-Related Outcomes, and Comorbid Pain Conditions

To analyze cervical tenderness scores (CTS) in patients with various temporomandibular disorders (TMD) and in controls and to examine associations of CTS with demographic and clinical parameters.

You, Your Esophagus and TMD

The esophagus is a roughly ten-inch hollow tube that descends from your throat through the diaphragm into the stomach. Normally, it is a one-way street transporting food you swallow to the stomach for digestion. But in GERD— Gastroesophageal Reflux Disease— the flow can reverse so that stomach contents (including gastric acids) are regurgitated upwards to cause a burning sensation (heartburn), nausea, pain and other distressing symptoms.

It's Time to Be Part of the Solution

The National Academy of Medicine (NAM) Study on Temporomandibular Disorders (TMD) is well underway. We strongly encourage everyone affected by TMD to write to the NAM committee letting them know what it is like to live with TMD and your experiences with getting care.

Cervical Muscle Tenderness in Temporomandibular Disorders and Its Associations with Diagnosis, Disease-Related Outcomes, and Comorbid Pain Conditions

  • Oct 4, 2019

The evidence is mounting for the inclusion of medical disciplines into TMD diagnostics and treatment. Many patients we hear from have cervical pain in addition to other issues in the cervical spine and upper back/shoulders and are being treated by physiatrists (medical doctors who treat a wide variety of medical conditions affecting the brain, spinal cord, nerves, bones, joints, ligaments, muscles, and tendons) or spine specialists. The abstract below acknowledges the involvement of the cervical area in TMD.

Abstract

AIMS: To analyze cervical tenderness scores (CTS) in patients with various temporomandibular disorders (TMD) and in controls and to examine associations of CTS with demographic and clinical parameters.

METHODS: This case-control study included 192 TMD patients and 99 controls diagnosed based on a questionnaire and a clinical examination following the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) guidelines. CTS, adapted from the widely used total tenderness score, was the mean sum of the palpation scores from the suboccipital, sternocleidomastoid, and trapezius muscles. Depending on the variables, data were analyzed using Pearson chi-square, analysis of variance, t test, Bonferroni post hoc adjustment, and/or multivariate linear regression analyses.

RESULTS: CTS was higher in TMD compared to controls (P < .001). Across TMD subgroups, CTS was notable only in those with a myogenous TMD diagnosis, but not in arthrogenous TMD (P = .014). CTS was positively associated with: female sex (P = .03), whiplash history, higher verbal pain scores, comorbid headaches, body pain, increased pain on mouth opening, and higher masticatory muscles tenderness scores (MTS) (P < .001 for all). Sex (P < .001), MTS (P < .001), comorbid headache (P = .042), and pain on opening (mild: P = .031; moderate: P = .022) retained significant associations with CTS in the multivariate analysis, and these main effects were influenced by interactions with whiplash history and comorbid body pain.

CONCLUSION: CTS differentiated between TMD patients and controls and between TMD diagnoses. Specific patient and pain characteristics associated with poor outcome in terms of CTS included effects of interactions between myogenous TMD, female sex, whiplash history, comorbid body pain and headaches, and pain on opening. It can therefore be concluded that routine clinical examination of TMD patients should include assessment of the cervical region.
