摘要
目的探讨干槽症的发生机制及其预防措施。方法对4897例下颌阻生第三磨牙拔除术患者资料进行回顾性分析,其中实施锤击凿骨劈冠拔牙2284例,涡轮机切割术拔牙2613例,比较2种方式拔牙术后干槽症的发生情况。结果锤击凿骨劈冠拔牙术式干槽症发生率为3.81%(87/2284),涡轮机切割拔牙术式无干槽症发生,二者比较差异有统计学意义(χ2=101.332,P<0.05)。结论锤击凿骨劈冠拔牙术后干槽症的发生可能是锤击拔牙时牙槽窝骨壁骨质遭受剧烈撞击挤压发生坏死的结果。涡轮机切割拔牙可以避免牙槽窝骨壁骨质遭受撞击挤压坏死,减少干槽症的发生。
Objective To discuss the etiology and prophylaxis measures of dry-socket.Methods A total of 4 897 cases of mandibular impacted third molar were randomly divided into two groups,2 284 cases in the group 1 were performed extraction by knocking chisel,while 2 613 cases in the group 2 were applied with extraction with turbine.The incidences of dry-socket were observed among these cases in both groups.Results The 87 cases of dry-socket were found in the group 1,and the incidence of dry-socket was 3.81%.No dry-socket was found in the group 2.The incidence of dry socket was significantly different between these two groups（χ2=101.332,P0.05）.Conclusion The dry socket may be resulted from necrosis of the alveolar bone due to the compression when the extraction is performed by knocking chisel.The alveolar bone will not be compressed and dry socket can be prevented if the teeth are extracted with turbine.
