One year evaluation of endodontic microsurgery in 54 cases with persistent apical periodontitis
摘要
Abstract
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.关键词
