This case control study was designed to investigate the contributing factors for the occurrence of temporomandibular disorder (TMD) and its subgroups: myofascial pain (MFP) and disc displacement (DD). 178 patients with TMD were selected from the dental clinics of the Jewish General and Montreal General Hospitals, Montreal, Canada, and 100 concurrent controls selected only at the first clinic, participated in this study. The association with TMD, MFP and DD was evaluated for bruxism, trauma, psychological factors, and sociodemographic status using a logistic regression. Migraine, depression, and clenching were associated with the occurrence of TMD. Among the MFP patients, clenching, clenching-grinding, anxiety, female, depression, and somatization were associated with disease occurrence. / In addition, adjusted analysis among the DD patients showed an association with clenching-grinding, orthodontic treatment, and anxiety. Our results identify possible risk factors that are associated with TMD, MFP, and DD occurrence. Further research needs to be conducted to look at these associations in depth.
