One year evaluation of endodontic microsurgery in 54 cases with persistent apical periodontitis / 华西口腔医学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the outcome of endodontic microsurgery in 54 cases with persistent apical periodontitis.</p><p><b>METHODS</b>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.</p><p><b>RESULTS</b>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).</p><p><b>CONCLUSION</b>The outcome of the present study indicates that endodontic microsurgery may result in a predictable treatment outcome in teeth with persistent periradicular lesions.</p>
