Abstract

Abstract: Objective: To investigate the correlation between the position of posterior scissor bite and the number of scissor bite and temporomandibular disorders. Methods: 77 cases diagnosed as temporomandibular disorders with posterior scissor bite were selected. The position of scissors bite and the number of scissor bite teeth were counted. Data were analyzed by SPSS.21 statistical software. Results: A statistically significant correlation existed between the occurrence of osteoarthrosis and cross-bite in molar teeth (P=0.02). The position of cross-bite in the second and the third molar were more significantly associated with osteoarthrosis than the first premolar (P<0.05). The number of scissors bite in posterior teeth was statistically correlated with osteoarthrosis (P=0.03). Conclusion: Osteoarthrosis is closely related to the position of posterior teeth with scissors bite and the number of scissors bite teeth.
