We observed 121 temporomandibular disorder patients who complated Cornel Medical Index questionnaires in order to investigate the corelation between temporomandibular disorders and psychological factors. All 121 patients were classified into 4 (I-IV) types by means of the criteria proposed by the Japanese Society for the Temporomandibular Joint. In addition, all 121 patients were classified into 4 (I-IV) categories in CMI. As a result, the type I of temporomandibular disorder patients significantly showed a tendency of shifting into CMI categories III and IV, compared with other types (II-IV) of temporomandibular disorder patients. It is suggested that the type I of temporomandibular disorder patients had many psychological factors.
