Stomatognathic system involvement in rheumatoid arthritis patients.

Abstract

AIMS:

Temporomandibular joint (TMJ) and stomatognathic system involvement are usually observed during the course of rheumatoid arthritis.

METHODOLOGY:

This article presents the findings during examination of 190 TMJs from rheumatoid arthritis (RA) patients, and 44 TMJs from controls without RA, including a description of signs and symptoms related to the stomatognathic system, radiological findings in hands-, and TMJ, erythrocyte sedimentation rate (ESR) values, and scores obtained in the Disease Activity Score (Das 28) and the Health Assessment Questionnaire (HAQ).

RESULTS:

The sample included 57.89% TMJs associated with spontaneous pain, 87.89% with signs of destruction in radiological images, and 58.94% with 20 teeth or less. Restricted mouth opening was detected in 42.1% of RA patients, from which 71% had blocked opening; headache was present in 58%, and pain in the masticatory muscles was found in 57%. TMJ erosions had a significant association with Larsen scores (r=0.62), but not with the Das 28, HAQ, and ESR values.

CONCLUSIONS:

The early evaluation of this joint and the collaborative work of odontologists and rheumatologists are both necessary for a better management of TMJ pathologies.
