title: Pathologic evaluation of disc dysfunction and osseous abnormalities of the temporomandibular joint.
abstract: The arthrographic findings in 141 patients with TMJ symptoms were compared with the linear tomographic evaluation to assess the incidence and severity of associated osseous abnormalities. Thirty-nine temporomandibular joints (28%) had significant osseous abnormalities compatible with degenerative joint disease. The incidence and severity of the degenerative changes compared favorably with the arthrographic assessment of the degree of soft-tissue injury. A cause-and-effect relationship between TMJ disc damage and dysfunction and degenerative arthritis is suggested.
