Although radiographic examination is generally used to diagnose lesions in the temporomandibular joint (TMJ), its reliability is still controversial. In this study, radio tomographic and single-contrast arthro tomographic findings were compared with arthroscopic findings in 34 joints of 28 patients with TMJ closed lock. The patients included 6 males and 22 females. Their ages ranged from 15 to 69 years old, with an average of 33 years.<BR>With regard to disk displacement, arthrographic findings agreed with arthroscopic findings in 33 out of 34 joints (97%). Regarding disk movement, both findings coincided in 29 out of 30 joints (97%). On the other hand, concidence of arthrographic and arthroscopic findings in disk deformation, anterior joint compartment adhesion and disk or retrodiscal tissue perforation were 53%, 66% and 74%, respectively. Moreover, tomographic and arthrographic examinations did not show abnormality on the surface of the mandibular fossa or articular eminence.<BR>These results suggest that tomography and single-contrast arthrography do not necessarily provide high reliability in the assessment of intracapsular lesions of the TMJ.
