Aim of the study. The objective of the current study is to determine if a correlation exists between bruxism and occlusal dysfunction. It was also investigated whether bruxism is influenced by musclo-articular status and/or is associated with dental-periodontal pathologies including dental wear, dental fissures, gingival retraction or abnormal dental mobility. Materials and method. The study was carried out in two stages. In the first phase an original bruxism questionnaire was distributed to the 180 subjects included in the study. Based on the answers two groups were formed: subjects with self-reported bruxism (n=60) and the second group without bruxism (n=120). In the second phase an intraoral examination was performed, including static and dynamic occlusion, masticatory muscles and temporomandibular joint (TMJ) evaluation. Dental signs of bruxism were also identified and registered (dental wear, gingival retraction or dental mobility). Results. Occlusal dysfunction and TMJ pain (83,3% vs 16,7%) or disc displacement (80% vs. 20%) were more frequently diagnosed in patients with bruxism. A significant correlation (p
