Targeted Endodontic Microsurgery: A Retrospective Outcomes Assessment of 24 Cases.

Introduction: Targeted endodontic microsurgery (TEMS) replaces freehand carbide or diamond bur osteotomy and root-end resection with a guided approach using an end-cutting trephine bur rotated within a guide tube. TEMS departs from traditional endodontic microsurgery in osteotomy size, control of resection level and bevel, surgical time, and resection method; yet, the impact of these departures on clinical outcomes has yet to be assessed. The aim of this study was to assess clinical outcomes of TEMS surgeries at least 1 year after treatment.
