摘要:

目的 分析第二磨牙正锁患者与头影测量指标的关系,评估第二磨牙正锁致病的相关危险因素,探寻不同人群中的敏感指标。方法 采用病例对照研究,选取第二磨牙正锁患者106例作为病例组。对照组为无锁且双侧磨牙及尖牙为中性关系的患者102例。比较2组患者年龄、性别、骨性和牙性测量指标差异。使用多因素Logistic回归进一步分析第二磨牙正锁致病的相关危险因素。结果 单因素分析结果显示,ANB角(∠ANB)、Wits值、覆(OB)、覆盖(OJ)、SNB角(∠SNB)是第二磨牙正锁的敏感指标。Logistic回归结果显示,对于整个研究人群,低角(OR=2.907,95%CI:1.157~7.307)、∠ANB(OR=1.643,95%CI:1.203~2.245)和OB(OR=1.442,95%CI:1.116~1.862)增大是第二磨牙正锁的危险因素。男性中,∠ANB增大是主要危险因素;女性的主要危险因素为高角、较大∠ANB和OB值。青少年中较大的∠ANB和OB值,以及成年人中较大的∠ANB和低角是该病的危险因素。结论 骨性Ⅱ类是第二磨牙正锁最主要的危险因素。此外,女性高角和深覆,青少年深覆以及成年人低角是第二磨牙正锁的高风险人群。

Abstract:

Objective To analyze the relationship between patients with second molar scissors-bite and cephalometric indicators, to assess risk factors associated with the pathogenesis of second molar scissors-bite, and to explore the sensitive indicators in different populations. Methods A case-control study was conducted with 106 patients with second molar scissors-bite (the case group). The control group was 102 patients without scissors-bite and with bilateral molars and cusps in a neutral relationship. Differences in age, sex, skeletal and dental measurements were compared between the two groups of patients. Risk factors associated with second molar scissors-bite were further analyzed using multifactor Logistic regression. Results Univariate analysis showed that five measures, ∠ANB, Wits value, OB, OJ and ∠SNB were sensitive indicators of second molar scissors-bite. Logistic regression showed that for the entire study population, low angle (OR=2.907, 95%CI: 1.157-7.307), ∠ANB (OR=1.643, 95%CI: 1.203-2.245) and OB (OR=1.442, 95%CI: 1.116-1.862) were risk factors for the pathogenesis of second molar scissors-bite. In males, large ∠ANB was the main risk factor for the pathogenesis of second molar scissors-bite. In females, the main risk factors for the pathogenesis of second molar scissors-bite were high angle and larger ∠ANB and OB. In adolescents, ∠ANB and OB value, and in adults, ∠ANB and low angle were risk factors for the pathogenesis of second molar scissors-bite. Conclusion Skeletal class Ⅱ is the most important risk factor for second molar scissors-bite. In addition, high angle and deep overbite in women, deep overbite in adolescents and low angle in adults are all at high risk of the pathogenesis of second molar scissors-bite.
