Objective To investigate the influence of abnormal occlusion factors on the incidence of temporomandibular disorders (TMDs) in junior college students and to provide an etiological basis for the prevention and treatment of TMDs. Methods We examined the temporomandibular joint (TMJ) and dental occlusion in 754 lower grade college students (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 abnormal occlusion and oral parafunctional activity) from the perspective of multivariate unconditioned logistic regression and univariate unconditioned logistic regression with dummy variables. Results The prevalence of TMD was 31.7%. The incidence 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 dummy variables 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 of TMD.

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、错牙合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)和前牙覆牙合关系(OR=1.228),与TMD的发病均有影响(P<0.05)。对不同程度前牙深覆牙合设置哑变量采用单因素非条件logistic回归分析显示深覆牙合程度越重,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 前牙覆牙合关系、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,前牙深覆牙合程度越重,TMD 发病风险越高。
