新疆医科大学大学生颞下颌关节紊乱病相关因素分析

Logistic regression analysis of risk factors of temporomandibular disorder in undergraduates of Xinjiang Medical University

目的:调查新疆医科大学学生颞下颌关节紊乱病发病情况,分析疾病的相关因素。方法:抽取新疆医科大学学生700名,其中男244名,女456名,平均年龄(20.08±1.457)岁,对其进行颞下颌关节检查、问卷调查(颞下颌关节相关病史,SCL-90自评量表),计算患病率,采用SPSS17.0软件包对数据进行处理,并对相关因素进行逻辑回归分析。结果:颞下颌关节紊乱病的患病率为42.40%,族别患病率差异无显著性。病史分析中,偏侧咀嚼习惯、夜磨牙习惯、口腔正畸治疗史、拔牙治疗史、心理因素均为危险因素。咬合因素中,前牙深覆、后牙正锁、个别牙扭转为危险因素。结论:口腔不良习惯、心理因素、错畸形与颞下颌关节紊乱病的发生有关。

PURPOSE： To investigate the prevalence of temporomandibular disorders（TMD） in undergraduates of Xinjiang Medical University and analyse its possible risk factors. METHODS： A sample of 700 medical students included244 males and 456 females was selected from Xinjiang Medical University and underwent examination of temporomandibular joint, questionnaire survey. Their average age was 20.08 ±1.457 years. Prevalence of TMD was analyzed, and the possible risk factors associated with the disease were identified by logistic regression analysis with SPSS17.0 software package. RESULTS： The prevalence of TMD was 42.40% in this population. There was no difference between different ethnics. Chewing-side preference, bruxism,orthodontic treatment,tooth extraction,psychological factors,anterior overjet, posterior scissors-bite were the main risk factors which increased the occurrence of TMD.CONCLUSIONS： Poor oral habits, psychological factors and malocclusion were related to the development of TMD.
