摘要
目的:了解下颌第三磨牙阻生牙患者的流行病学分布特征及其对干槽症发病的影响。方法:分析1 777例下颌第三磨牙阻生牙拔出患者的年龄、性别、拔牙月份、牙位、阻生类型等流行病学特征的分布情况,并采用多因素Logistic回归分析探讨其与干槽症发病的关系。结果:1 777例患者平均年龄(33.69±11.57)岁,女性患者(60.33%)多于男性(39.67%),垂直阻生和近中阻生患者最多(37.76%和31.40%),颊侧阻生患者最少(0.79%)。共有15例患者发生干槽症,发病率0.84%。多因素Logistic回归分析结果显示,5~10月拔除下颌第三磨牙阻生牙(OR=4.07,95%CI:1.08~15.42)、远中阻生(OR=12.19,95%CI:1.19~125.01)、舌侧阻生(OR=15.30,95%CI:2.59~90.36)与干槽症发病均呈正相关(P<0.05)。结论:下颌第三磨牙阻生牙拔除患者中女性较多,阻生类型以垂直阻生和近中阻生为主,较炎热季节行拔牙术、阻生类型是干槽症发病的危险因素。
Objective: To study the epidemiological features of impacted mandibular third molar and to investigate their effects on dry socket morbidity following tooth extraction. Methods: 1 777 patients with impacted mandibular third molars extraction were analyzed for the distribution of their age, gender, extraction month, tooth position and impaction types. Multiple logistic regression analysis was used to explore the relationship between the epidemiological features of patients and dry socket morbidity. Results: The average age of the patients was 33.69±11.57 years. The female and male patients comprissed 60.33% and 39.67% of all. For impacted types, the patients with vertical impaction and mesioangular impaction were the most(37.76% and 31.40% respectively), while the buccoangular impaction was the fewest(0.79%). The dry socket was reported in 15 patients(0.84%). The results of multiple logistic regression analysis showed that impacted mandibular third molar extracted from May to October(OR=4.07,95%CI:1.08~15.42), distoangular impaction(OR=12.19,95%CI:1.19~125.01) and distolingual impaction were positively correlated with dry socket attack(P<0.05). Conclusion: Among the patients with the extraction of impacted mandibular third molar, females are more common, and vertical impaction and mesioangular impaction are the main types. The operation in hot season and impacted type are risk factors for dry socket.
