Abstract　： Dental examinations have been done to a general population working in an office. The association among bruxism, temporomandibular disorder (TMD) and dental diseases are examined in a sample of 1347 subjects. We checked for dental diseases, TMD using the axiography, grinding pattern by the BruxChecker (BC, a device developed to check the grinding pattern during sleep bruxism) and dysfunction symptoms through interviews as to the occlusion. The grinding patterns at the BC were classified into the canine dominance griding (CG) and group function grinding (GG). Comparisons among the dental diseases, interviews, mandibular movements and the classification of the BC were accomplished. Interviews have shown that GG group had the tendency to have click, difnculty in opening mouth and jaw pain. The appearance of cervical lesions in the GG group showed significantly higher appearance than that in the CG group based on the grinding pattern. Examination of condylar movements indicated that the saggital condylar inclination was significantly stepper in CG group than that in GG group. It was suggested that sleep bruxism would influence the appearance of the cervical lesions and TMD.
