Apicoectomy is a surgical endodontic procedure which is performed through the gingival tissues and  the supporting bone of a tooth.

During an apicoectomy the inflamed periapical tissues are removed and the apical portion of the root (2-3 mm.) is resected and a biocompatible retrofilling material is placed at the end of the root to properly seal the root canal.

Modern surgical endodontic procedures are performed through the use of clinical microscope using small ultrasonic instruments for better visibility and minimum tissue injury.
