摘　　要：目的:比较三氧化物多聚体(mineral trioxide aggregate,MTA)和Vitapex糊剂应用于成人慢性根尖周炎伴根尖闭合不全恒牙的临床疗效。方法:选取成人慢性根尖周炎伴根尖孔闭合不全的恒牙共38颗,随机分为2组,实验组在根管显微镜下用MTA严密封闭根尖开放部位,硬固后根管行热牙胶充填;对照组用Vitapex糊剂行根尖诱导成形,在根尖部有硬组织形成后行根管充填。两组术后均定期复查,评价临床效果及X线片结果。结果:经过2年的复查,实验组所有病例在治疗后均无临床不适症状,X线片显示患牙11颗根尖阴影完全消失,8颗明显缩小,1颗无变化,有效率95%。对照组2颗磨牙因冠根折拔除,8颗根尖有硬组织形成,8颗根尖无硬组织形成,有效率为44.4%,两者差异有统计学意义。结论:MTA治疗成人根尖孔未闭合恒牙是一种较理想的根尖诱导成形材料,短期临床疗效好,长期效果有待于进一步观察。Objective：To evaluate the clinical effects of the treatment of open apical teeth with chronic periodontitis using mineral trioxide aggregate（MTA）and Vitapex paste.Methods：Thirty-eight cases,with open canal system,were selected and divided into two groups at random.In the experimental group,the apical root canals of 20 teeth were filled with MTA to creat a 3-5mm apical barrier under operative microscope.The canals of 18 teeth in control were treated with Vitapex.All cases were recalled for clinical and radiographic evaluation.Results：All the cases in experimental group had no clinical symptom after treatment.The recall radiographs indicated that the apical radiolucent areas of the teeth with pre-existing apical lesion decreased apparently or disappeared completely,except one tooth without change.The efficacy rates was 95%.In the control group,the apexification of 8 teeth succeeded and 10 failed.The efficacy rates was 44.4%.There was significant difference between two groups.Conclusion：MTA may be an ideal material in treatment of teeth with open apices.Long-term studies with more cases should be performed to evaluate the curative effect of MTA.
