It is likely that the contralateral side of the temporomandibular joint is affected in patients suffering from unilateral temporomandibular joint dysfunction, because both joints are connected to the rigid mandible. The purpose of this study was to ascertain the prevalence of anterior disk displacement on the contralateral side in consecutive 112 patients with unilateral temporomandibular dysfunction. 47% of the total patients had anterior disk displacement on the contralateral side, whereas 73% had it on the symptomatic side. Prevalence of anterior disk displacement on the contralateral side increased in proportion to the degree of anterior disk displacement on the symptomatic side.
