摘　　要：目的对比研究儿童前牙外伤脱位先行根管治疗后再植和先再植必要时行根管治疗两种方法的临床疗效。方法 90例患儿外伤致前牙脱位共125颗,随机分为两组:实验组行根管治疗后再植,对照组再植3个月后行根管治疗,比较两种治疗方法的牙根吸收情况,并进行统计学分析。结果两组患儿脱位前牙再植时间越早,再植成功率越高。实验组患儿脱位前牙再植时间在<30min、30～60min、>60min的成功率均较对照组高(P<0.01),而失败率均较对照组低(P<0.05或<0.01)。结论对儿童外伤脱位前牙先行根管治疗再植有利于提高再植的成功率。Objective To compare the clinical effect of the following two replantation methods on traumatic an- terior teeth dislocation of children： rcplantation after root canal therapy and replantation followed by necessary root canal therapy. Methods 125 traumatic dislocational anterior teeth of 90 children were randomly divided into two groups. The experimental group was first treated by root canal therapy before replantation. The control group was first treated by replantation,then by root canal therapy 3 months later. Then root resorption of the teeth treated hy the 2 methods were compared and analysed statistically. Results The earlier the dislocational anterior teeth were replan- ted,the higher the success rate was gotten in the two groups. Compared with the control group, the experimental group had a higher success rate of replantation in less than 30 min, from 30 min to 60 rain and over 60 min（ P 〈0. 01） ,but had a lower failure rate（ P 〈0.05 or 〈0.01）. Conclusion Based on the above analysis,conducting root canal therapy before replantation is beneficial to improve the success rate of replantation on traumatic dislocational anterior teeth of children.
