Patients and Methods
The study population comprised patients of both genders and various social backgrounds suffering from RA undergoing treatment at the Department of Rheumatology, Pernambuco Federal University Hospital, between December 2003 and December 2004. The following inclusion criteria were adopted: a diagnosis of RA according to the American College of Rheumatology's 1987 criteria, no previous treatment of any kind for TMJ involvement, and a sufficient number of teeth (or tooth prostheses) for obtaining
Results
The duration of RA ranged from 9 months to 65 years, with a mean of 12 years (standard deviation, 11 years, 3 months). Of the total group, 32.8% had RA of up to 5 years' duration, 24.6% had RA of 5 to 10 years' duration, and 42.6% had RA of more than 10 years' duration. With regard to positivity for rheumatoid factor, 55.7% were positive and 44.3% negative. The HAQ assessment, 32.8% had a score of up to 1 and 67.2% had a score of 1 to 3 (37.7% between 1 and 2 and 29.5% between 2 and 3). Of
Discussion
Performing a targeted assessment of the TMJ in patients with RA requires special care owing to the fact that a large percentage of these patients have symptomatology. In terms of overall figures, 70.5% of the patients presented with at least 1 sign or symptom, 49.2% had at least 1 symptom, and 54.1% had at least 1 sign. These findings are in agreement with other published studies showing that 33% to 66% of the patients with RA have some sign or symptom of TMJ involvement; however, analysis of

2022, Journal of Oral Biology and Craniofacial ResearchCitation Excerpt :Common diagnostic imaging modalities include panoramic radiographs, computerized tomography (CT) scans and magnetic resonance imaging of the TMJ. Frequent findings on these include loss of joint space, articular disc flattening and displacement, osseous changes to both the condyle as well as the articular eminence/glenoid fossa (degeneration or heterotopic bone formation), synovitis and abnormal bone marrow signal.1,14 More advanced destruction of the joint can result in a decrease in condylar height that subsequently leads to the presence of a high occlusal plane angle, increased mandibular plane angle, decreased chin projection, and A-P mandibular deficiency (Fig. 1).
