摘　　要：目的:探讨脱位再植牙根管处理的最佳时机。方法:42例49颗脱位再植牙随机分为3组,A组:术前去髓,根充氢氧化钙,半年后常规根充。B组:直接再植,再植术后1周去髓,根充氢氧化钙,半年后常规根充。C组:直接再植,出现牙髓病变时根充氢氧化钙,半年后常规根充。结果:A组与B组的有效率分别为81.25%和94.44%,两者间疗效无显著差异;且A、B两组的疗效均显著优于C组(53.33%),P值均<0.05。结论:牙脱位时间在3h内,再植术后1周行去髓根充氢氧化钙,半年后再行常规根充为较理想的根管处理时机及治疗方法。PURPOSE: To investigate the opportunity of different root canal therapies in replantation of tooth due to injury. METHODS: 49 cases with teeth luxation were randomly divided into three groups. In group A, the pulp was removed before replanted, and calcium hydroxide was filled in root canals and condensated routinely after half a year. In group B , the pulp was removed one week after being replanted . In group C, the pulp was removed until pulp disease. RESULTS: The effect of group A(81.25%)and B(94.44%) was better than group C(53.33%),P<0.05 .And the effect of group A and B was similar. CONCLUSION: It's an ideal method to replant luxated tooth within 3 hours with removal of pulp tissue, root canal filling with calcium hydroxide one week after replantation of tooth and condensated routine root canal therapy after half a year.
