In this study, statistical methods about the relationship between with three-dimensional mandibular movements, clinical findings and the disc perforation of 36 patients that were diganosed as anterior disc displacement without reduction, were investigated by the video-fuluoroarthrography. As a result, an obvious relation was not confirmed between disc perforation and mandibular movements. Also the condylar deformity was the relational factor of disc perforation, and the odds ratio was 9.0. In the result, to diagnose disc perforation, yet it was thought that arthrography was indispensable.
