Long-term Follow-up of Intra-articular Injections into the Tem-poromandibular Joint in Patients with Rheumatoid Arthritis

• A long-term (12 years) follow-up of treatment with intra-articular in-jections into the temporomandibular joint (TMJ) of steroid or non-steroid agents was performed in 21 patients with rheumatoid arthritis (RA) and symptomatic TMJs. The aim of the study was to compare symptoms, signs and radiological appearance of the TMJ initially and at the follow-up in this group of patients. Eleven patients were as-signed to a steroid group and 10 patients to a non-steroid group. Ini-tial and follow-up clinical and radiological examination procedures were the same. The radiological evaluation was based on a grading system using standard reference films. At follow-up, 14 patients re-ported no pain from the TMJ and positive changes in most clinical variables were found in both groups. Radiographic follow-up exami-nation was performed on 12 patients. Initially, all but 4 of the 24 joints had structural bone changes. At follow-up, 2 joints had lower, 11 joints had unchanged and 11 joints had higher radiological grades. Two out of 5 and 3 out of 10 joints in the steroid and non-steroid group, respectively, showed progression of structural bone changes. Among 9 untreated joints, 6 had higher radiological grades and 3 were unchanged. In the 11 TMJs with higher radiological grades at follow-up, there was in most cases moderate progression of erosive changes. The results suggest that the long-term development of symptoms and signs from the TMJ in patients previously treated was good and the long-term progression of joint destruction was low for both steroid and non-steroid agents in this patient group with RA.
