后牙锁与颞下颌关节紊乱病的相关性研究

Study on Correlation between Posterior Teeth with Scissors Bite and Temporomandibular Disorders

目的:探讨后牙锁[牙合]牙位、锁[牙合]牙数与颞下颌关节紊乱病的相关性。方法:收集颞下颌关节疾患伴后牙锁[牙合]患者77例,统计锁[牙合]发生牙位、牙数等,通过SPSS 21.0统计软件分析数据。结果:骨关节病的发生与磨牙锁[牙合]有显著的相关性( P =0.02);第二、三磨牙锁牙合较第一前磨牙锁[牙合]引起的骨关节病均有显著的相关性( P <0.05);后牙锁[牙合]牙数多者与骨关节病的发生显著相关( P =0.03)。结论:锁[牙合]发生的牙位越后,锁[牙合]牙数越多者,与骨关节病的发生越密切相关。

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.
