Clinical and radiographic findings of the temporomandibular joint in patients with various rheumatic diseases. A case-control study

The TMJ is commonly affected in patients with RA, and in patients with other forms of rheumatic disease. There are associations between radiographic findings and subjective symptoms, and between radiographic findings and restricted TMJ movement. In screening for suspected TMJ destruction, it would be appropriate to look for restricted maximal mouth opening, masticatory muscle tenderness and restricted laterotrusion.
