OBJECTIVE
To evaluate the outcome of endodontic microsurgery in 54 cases with persistent apical periodontitis.
METHODS
All surgical procedures were performed under a dental operating microscope after root canal treatment. 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 predictable treatment outcome in teeth with persistent periradicular lesions.
目的
评估54例持续性根尖周炎患者行牙髓显微外科手术的效果。
方法
所有手术操作均在根管治疗后于牙科手术显微镜下进行。手术操作包括根尖刮治、根尖切除术、用超声微尖进行倒预备以及用三氧化矿物凝聚体（MTA）进行根尖充填。通过临床和影像学检查监测愈合情况。
结果
1年后，31例（57.41%）治愈，19例（35.19%）好转，4例（7.41%）失败。性别、年龄、牙位、病变大小及病理特征之间无统计学差异（P>0.05）。
结论
本研究结果表明，牙髓显微外科手术对于患有持续性根尖周病变的牙齿可能会产生可预测的治疗效果。
