Surgical endodontic reintervention using a modern technique: 2 case reports.

Management of post-treatment apical periodontitis after surgery--assuming the tooth is restorable, periodontally sound, and the patient desires to retain it--includes nonsurgical retreatment and surgical reintervention. This article presents 2 cases of surgical reintervention using a modern surgery technique that utilized an operating microscope, ultrasonic tips, and biocompatible materials. After the reinterventions were performed, adequate periradicular healing was observed in both cases. These cases reinforce the precept that combining knowledge about the biologic aspects of endodontics with surgical endodontic treatment using a modern technique is a predictable treatment option.
