目的:探讨颞下颌关节紊乱病(TMD)发病危险因素。方法:选择TMD伴缺牙1434例为观察组,另外选择单纯因缺牙要求修复1501例为对照组。TMD症状和体征采取问诊及临床检查方式。记录性别、年龄、缺前牙数、非游离端缺磨牙数、游离端缺磨牙数,进行单因素和多因素Logistic回归分析,探讨TMD发病危险因素。结果:单因素Logistic回归分析结果显示,性别、年龄、缺前牙数、非游离端缺磨牙及游离端缺磨牙数与TMD均关系密切(P<0.05,P<0.01)。多因素Logistic回归分析结果显示,性别(OR=0.586,95%CI:0.486~0.708)、年龄(OR=0.776,95%CI:0.724~0.831)、缺前牙数(OR=0.664,95%CI:0.607~0.727)、非游离端缺磨牙数(OR=0.876,95%CI:0.851~0.912)等因素与TMD呈负关联;游离端缺磨牙数(OR=1.018,95%CI:1.003~1.314)与TMD呈正关联。结论:游离端缺磨牙数是TMD发病的重要危险因素;女性、年轻者、非游离端缺磨牙较少者易发生TMD,游离端缺磨牙较多者易发生TMD。
Objective: To explore the risk factors of temporomandibular disorder (TMD). Methods: 1434 cases of TMD with missing teeth were selected as the observation group. Another 1501 cases were selected as the control group simply because of missing teeth. TMD symptoms and signs to ask the way and clinical examination. The gender, age, number of teeth missing, number of missing teeth at the free end and number of missing teeth at the free end were recorded. Univariate and multivariate logistic regression analysis were performed to explore the risk factors of TMD. Results: The results of univariate Logistic regression analysis showed that there was a close relationship between TMD and gender, age, number of anterior teeth missing, teeth with non-free ends and free ends with TMD (P <0.05, P <0.01). Multivariate Logistic regression analysis showed that there was no significant difference in age (OR = 0.776, 95% CI: 0.724-0.831), anterior teeth number (OR = 0.664, 95% CI : 0.607-0.727). There was a negative correlation between TMD and the number of missing teeth (OR = 0.876, 95% CI: 0.851-0.912) ) Is positively related to TMD. Conclusions: The number of teeth missing from the free end is an important risk factor for the development of TMD. TMD is more likely to occur in females and young people than in those with fewer free teeth and those with more free teeth.
