[Study on internal derangement in temporomandibular joint of temporomandibular joint dysfunction syndrome patient in adolescent by means of Fuji Computed Radiography (FCR)].
The aim of this study was to examine the Temporomandibular Joint of the thirty-eight adolescent subjects with Temporomandibular Joint Dysfunction Syndrome by means of Fuji Computed Radiography System (FCR). The following results were obtained: 1) It was indicated that the frequency of occurrence of the backward on the condyle position to fossa in the group with signs of TMJ Dysfunction was higher than the group without signs. Also it was suggested that the central position was a good position as the goal for improved position. 2) The revealed frequency of morphological abnormality of condyle in the group with signs was higher than the group without signs. 3) Internal derangement of meniscus was associated with signs of TMJ Dysfunction. In particular, sound and pain was definitely associated with the internal derangement. 4) The organic abnormal change (morphological abnormality of the condyle and internal derangement of meniscus) in the TMJ of adolescent patients with the TMJ Dysfunction Syndrome was found.
