目的对比分析高速涡轮钻拔牙法和凿骨劈冠法对于下颌阻生智齿拔除后并发干槽症的影响。方法选择2010年1月至2012年12月沈阳市苏家屯区中心医院口腔科收治的单颗近中水平阻生下颌智齿患者186例(186颗患牙),随机等分为2组:试验组采用高速涡轮钻法拔牙,对照组采用凿骨劈冠法拔牙。术后4d进行随访,以确诊有无干槽症的发生。结果试验组术后并发干槽症的发生率(1.08%)低于对照组(7.53%),差异有统计学意义(P<0.05)。结论与传统凿骨劈冠法相比,采用高速涡轮钻拔牙法拔除下颌阻生智齿,可有效减少术后干槽症的发生。
Objective To compare and analyze the influence of high-speed turbine tooth extraction and chisel splitting on mandibular dysfunction after mandibular impacted wisdom tooth extraction. Methods A total of 186 patients (186 teeth) with single near-mid-level impacted mandibular wisdom teeth admitted to Department of Stomatology, Central Hospital of Sujiatun District, Shenyang from January 2010 to December 2012 were randomly divided into two groups: Group using high-speed turbine drilling tooth extraction, control group using chisel split crown extraction method. 4d after follow-up to confirm the occurrence of dry groove disease. Results The incidence of postoperative dry socket syndrome in experimental group (1.08%) was lower than that in control group (7.53%), the difference was statistically significant (P <0.05). Conclusion Compared with the traditional chisel splitting crown method, removal of mandibular impacted wisdom teeth by high-speed turbine tooth extraction can effectively reduce the occurrence of postoperative dry socket disease.
