Correlation of clinical findings of temporomandibular joint with serological results in rheumatoid arthritis patients.

The frequency of TMJ involvement clinically was 15% in Group A and 40% in Group B. The most frequently observed clinical symptom was facial pain (25%), and the slightest symptom was clicking (2.5%) during mouth opening. There was a positive correlation between ESR, RF, CRP and anti-CCP and clinical sign and symptoms of TMJs in RA patients. An elevated ESR, RF CRP and anti-CCP may indicate the presence of TMJ complains in RA patients. The chronicity of RA affects the frequency of TMJ involvement clinically, patients with longer disease duration have more clinical symptoms of TMJs. An elevated level of ESR, RF, CRP and anti-CCP predict clinical symptoms of TMJs.
