摘　　要：目的:对拔除下颌阻生智齿术后干槽症发病率进行临床回顾分析。方法:共收集1038例,对2002至2004年426例(甲组)与2005至2007年612例(乙组)拔除下颌阻生智齿术后干槽症发生率进行!2检验。结果:拔除下颌阻生智齿术后甲乙两组干槽症发生率分别为5%和0.8%。干槽症发生率差异有显著性(P<0.005),乙组发病率明显降低。结论:常规应用一次性器械,四手操作,预先制订详细的手术方案,熟练地运用涡轮机配合拔牙操作技能,加强术后处理,可以降低干槽症的发生。Objective：To retrospectively study the incidence of dry socket after mandibular impacted wisdom tooth extraction.Method：1038 cases were reviewed.The mandibular impacted wisdom tooth extraction patients were divided into two groups according to their treatment date：group A of 426 cases treated from the year 2002 to 2004;group B of 612 cases from the year 2005 to 2007.Then the incidence of dry socket of the two groups compared for X2 test.Result：The incidence of group A and B was 5% and 0.8% respectively,it was significantly lower in group B （P〈0.005）.Conclusion： The routine applies of the disposable instrument,four hand operation,detailed surgery plan in advance,skillfully using turbines for extraction,and enhancement of postoperative treatment may reduce the incidence of dry socket.
