摘要
目的评价显微根尖手术治疗54例持续性根尖周炎病例的短期临床疗效。方法对54例持续性根尖周炎病例进行显微根尖手术,包括翻瓣、去骨、根尖周刮治、根尖切除,使用超声器械倒预备,三氧化矿物凝聚体(MTA)作为倒充填材料,术后定期复查,通过临床和X线片检查和测量,评价术后疗效。结果 54例持续性根尖周炎病例术后1年随访,治愈者31例(57.41%),改善者19例(35.19%),失败者4例(7.41%)。根据患者性别、年龄、牙位分布、根尖周暗影的最大直径和根尖周病变组织病理分类分别统计显微根尖手术的疗效,组间差异均无统计学意义(P>0.05)。结论显微根尖手术明显提高持续性根尖周病变的治疗成功率。
Objective To evaluate the outcome of endodontic microsurgery in 54 cases with persistent apical perio-dontitis.Methods All surgical procedures were performed under a dental operating microscope after root canal treat-ment.Surgical procedures included periapical curettage,root-end resection,retropreparation with ultrasonic microtips,and root-end filling with mineral trioxide aggregate（MTA）.Healing was monitored clinically and radiographically. Results One year later,31（57.41%） cases were cured,19（35.19%） cases were improved,4（7.41%） cases were failure.There were no statistical difference between sex,age,tooth location,size of the lesion and pathological features（P 0.05）.Conclusion The outcome of the present study indicates that endodontic microsurgery may result in a predic-table treatment outcome in teeth with persistent periradicular lesions.
