title: [Radiographic findings in osteoarthrosis of temporomandibular joint in relation to its pathologic changes].
abstract: We analysed the results of the central standard lateral tomographic findings and the macroscopic/microscopic observations on the middle portion of the autopsy materials of 84 temporomandibular joints. It was not suitable to differentiate remodeling and osteoarthrosis of the temporomandibular joint only by whether the surface articular zone of the articular cartilage is intact or not. The early changes of osteoarthrosis could occur in the interface of the bone-cartilage except occuring in the articular zone, even though the surface articular zone was intact. Therefore, we suggest that the definition of osteoarthrosis should be wider. Histopathologic observations proved that the definte radiographic signs, such as sclerosis, erosion, pseudocyst, osteophyte and so on showed on the lateral tomographs were credible signs in the diagnosis of osteoarthrosis.
