【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。更多还原

【Abstract】 Objective:To retrospectively study the incidence of dry socket after mandibular impacted wisdom tooth extraction.Method:1 038 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.更多还原
