摘　　要：目的探讨低年级大学生咬合异常因素对颞下颌关节紊乱病(temporomandibular disorders,TMD)发病的影响,以期为TMD的防治提供病因学基础。方法对遵义医科大学珠海校区低年级学生754名(男性354名,女性400名)进行颞下颌关节检查、牙列与咬合关系检查、问卷调查,采用多因素非条件logistic回归分析与哑变量单因素非条件logistic回归分析咬合功能异常、错畸形以及口腔副功能运动等咬合异常因素与颞下颌关节紊乱病的关系。结果颞下颌关节紊乱病的患病率为31.7%,多因素非条件logistic回归分析结果显示夜磨牙(OR=2.070)、日间紧咬牙(OR=2.553)、无意识空嚼(OR=2.642)和前牙覆关系(OR=1.228),与TMD的发病均有影响(P<0.05)。对不同程度前牙深覆设置哑变量采用单因素非条件logistic回归分析显示深覆程度越重,TMD的发病风险越高[轻度(OR=1.558)、中度(OR=2.189)、重度(OR=3.236),P<0.05]。结论前牙覆关系、夜磨牙、日间紧咬牙、无意识空嚼均是低年级大学生TMD发病的危险因素,前牙深覆程度越重,TMD发病风险越高。Objective To investigate the influence of abnormal occlusion factors on the incidence of temporoman⁃dibular disorders (TMDs) in junior college students and to provide an etiological basis for the prevention and treatmentof TMDs. Methods We examined the temporomandibular joint (TMJ) and dental occlusion in 754 lower grade collegestudents (male 354, female 400) at Zunyi Medical University (Zhuhai campus). A questionnaire was also administered.We analyzed the correlation between TMD and the other three factors (static abnormal occlusion, dynamical abnormalocclusion and oral parafunctional activity) from the perspective of multivariate unconditioned logistic regression and uni⁃variate unconditioned logistic regression with dummy variables. Results The prevalence of TMD was 31.7%. The inci⁃dence of TMD was significantly (P<0.05) associated with sleep bruxism (OR=2.070), clenching (OR=2.553), diurnal(OR=2.642) and anterior teeth overbite (OR=1.228). Univariate unconditioned logistics regression analysis by dummyvariables was used to analyze the incidence of TMD at different deep overbites (mild, OR=1.558;moderate, OR=2.189;severe, OR=3.236;P<0.05). Conclusion The risk factors for TMD in lower grade college students included anterior teeth occlusion, sleep bruxism, clenching, and diurnal treatment. Worse deep overbite might increase the risk ofTMD.
