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.

Some Thoughts on Depression

It is hardly surprising that the chronic pain and limitations in function that many long-time TMJ patients experience can be accompanied by a state of depression, a sense of exhaustion and hopelessness.

Prevalence of TMD in Sjӧgren Syndrome Patients

  • May 30, 2018

Abstract

Aims: Sjӧgren Syndrome is a disorder involving oral tissues, with xerostomia, dysgeusia, dysphagia, tooth decay, gingivitis, angular cheilitis and glossitis. Temporomandibular disorders are a generic term referred to clinical conditions involving the jaw muscles and temporomandibular joint. The aim of this study was to investigate the prevalence of oral manifestations and temporomandibular disorders (TMD) in Sjӧgren Syndrome (SS) patients compared with healthy people.

Methods: The study group included 72 SS patients (2 men, 70 women) diagnosed according to the American-European Consensus Group (AECG) Criteria. A randomly selected group of 72 patients, matched by sex and age, served as control group. The examination for TMD signs and symptoms was based on the standardized Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) through a questionnaire and clinical examination.

Results: SS patients complained more frequently (95.8%) of oral symptoms (xerostomia, dysgeusia, dysphagia) than controls (22.2%) (χ2= 80.66 p< 0.001). TMD symptoms (muscle pain on chewing, difficulty in mouth opening, arthralgia, headaches, tinnitus) were complained by 91.7% of SS patients and by 84.7% of controls (χ2= 1,667 p= 0,196). At the clinical examination, 91.7% of SS had at least one oral sign respect to 75% of controls. The salivary flow measurements showed high statistical significance between the two groups (Unpaired test, p< 0,0001). Myofascial pain (caused by muscular contracture) was significantly higher in the study group than in the control one (p≤0,05). Furthermore 18.05% of SS patients showed deflection versus 5.5% of controls (χ2=5,402 p=0,020).

Conclusions: Sjӧgren's Syndrome seems to play a role in temporomandibular joint disorders.
