Temporomandibular joint findings in patients with rheumatoid arthritis, ankylosing spondylitis, and primary Sjögren's syndrome

Abstract

TMJ symptoms were observed to be higher in the patients with RA, AS and pSS than the control group. Dentists and rheumatologists should be aware of TMJ symptoms in patients with rheumatic diseases.

Orofacial Manifestations and Temporomandibular Disorders of Sjögren Syndrome: An Observational Study

“…The results about joint sounds during mandibular movements do not deviate from Keris 41 , except for a significant prevalence in the SS group regarding to pop noise. Moreover, they differ in a work by List 22 , that showed 57% of SS patients had clicking.…”

“…The most common symptom in patients with SS was myalgia during palpation and arthralgia, as reported by Y. Keris et al 41 , having considered the posterior, middle and anterior part of the temporalis muscle, masseter muscle, lateral and medial pterygoid muscles.…”

“…The present study analyzed the prevalence of oral manifestation and TMD symptoms and signs in SS patients compared with healthy controls, with a cohort size larger than other studies investigating SS and TMD (72 SS versus 1 in Burges 40 , 21 in List et al 22 , 23 in Keris et al 41 .…”

Prevalence of Temporomandibular Joint Disorders in Patients with Ankylosing Spondylitis: A Cross-Sectional Study

“…Some authors argued about the relationship between AS and temporomandibular disorders (TMD). 8 , 9 Although not fully understood, destruction of joint capsule or components of the disc, synovitis in TMJ with a breakdown of the articular surfaces, and craniocervical postural changes due to AS are believed to be possible mechanisms underlying the TMJ involvement. Noteworthy, ankylosis is rare in the TMJ probably due to the presence of the intra-articular disc as a physical barrier.…”

“…In general, scientific reports that considered the use of imaginological methods and objective and subjective symptoms to diagnose TMD found a prevalence between 30% and 37%. 8 , 9 , 11 However, these methods did not follow standardized criteria and did not consider a comprehensive evaluation of the TMD. To overcome this deficiency, Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) system was proposed in 1992 12 and updated in 2016 for Diagnostic Criteria for Temporomandibular Disorders (DC/TMD).…”
