Ultrasonography of the temporomandibular joint: Comparison of findings in patients with rheumatic diseases and temporomandibular disorders. A preliminary report

Temporomandibular joint involvement in patients with rheumatic diseases seems to be similar to that described in subjects with temporomandibular disorders. Ultrasonography confirmed to be an accurate technique to detect disc displacement and effusion within the temporomandibular joint, but not to detect condylar abnormalities.
