[摘要]目的探讨单纯性根管治疗和根管治疗辅以根尖切除治疗前牙根尖周囊肿的疗效。方法将91颗前牙根尖周囊肿行根管治疗后随机分为2组，44颗作为试验组，行根尖切除术，另外47颗作为对照组。术后3个月到1年跟踪追访。结果试验组治疗的有效率为90.9%，对照组治疗的有效率为87.2%，且两组间的疗效差异无统计学意义(P>0.05)。结论对于前牙根尖周囊肿，应先行根管治疗，待明确效果后再考虑是否需要外科手术治疗，根尖切除不是必须的治疗方法。

    [Abstract]ObjectiveThe purposes of this study was to investigate the curative effect difference of periapical cyst on anterior teeth treated by root canal therapy and root canal therapy combined apicectomy. MethodsThe study included clinical cases with periapical cysts on 91 anterior teeth that were treated by root canal therapy. These teeth were randomly assigned to two groups. 44 teeth were treated by apicectomy as experimental group while 47 teeth as controls. All teeth were followed clinically and radiographically examinations for a period ranging from 3 months to 1 year. ResultsThe results of experimental group showed 90.9%success and the other group was 87.2% success. The difference was not significant(P>0.05). ConclusionRoot canal therapy is effective in treating the anterior teeth with periapical cysts. Apicectomy should be done only when root canal therapy was ineffective. ......
