目的:探讨颞下颌关节紊乱病(TMD)在新疆医科大学维汉青年人中的患病情况。方法:对新疆医科大学812名在读维汉医学生(年龄17～28岁)进行了TMD患病状况及咬合情况调查。按照Helkimo指数进行分析,包括既往功能紊乱指数和临床检查功能紊乱指数。采用SPSS13.0软件包对数据进行χ2检验。结果:无既往功能紊乱者(Ai0)占73.40%,既往功能紊乱者(AiI+Ⅱ)占26.60%,无临床检查功能紊乱者(DiO)占60.50%,临床检查功能紊乱者(DiI～Ⅲ)占39.50%。结论:TMD的患病率为39.50%,男女患病率无显著差异,异常组发病率显著高于正常组,TMD的发生与夜磨牙、偏侧咀嚼有关。

PURPOSE： To investigate the prevalence and distribution of temporomaudibular disorders （TMD） and the related factors to TMD in Uigur and Han young people （17-28 years） from Xinjiang Medical University. METHODS： A sample of 812 persons was randomly selected from Xinjiang Medical University. Subjective disorders were assessed using questionnaire, and objective symptoms were determined by clinical examination. The Anamnestic and Clinical Dysfunction Indices （Ai and Di） according to Helkimo were employed. SPSS13.0 software package was used for data analysis. RESULTS： The percentage distribution of the sample was as follows ：AIO=73.40 %, Ai I＋ II = 26.60%, Dio=60.50%, Di I -III = 39.50 %. CONCLUSIONS： The prevalence of temporomandibular joint disorders was 39.50%. In anamnestic symptoms and clinical symptoms, there was no significant different between the males and females. ③The incidence of TMD in malocclusion group was higher than that in group without malocclusion. TMD is associated with some factors as bruxism, lateral biting.
