Clinical and radiologic re-examination of apicoectomized teeth.

Healing after periapical surgery was studied clinically and radiologically in 108 patients in whom apicoectomy had been performed on 174 teeth. Histologic diagnosis was used to determine healing results; teeth with periapical granuloma tend to heal less successfully than teeth showing inflammation or cysts. Postoperative treatment played an important role in the healing process. In making a prognosis one must include preoperative status (including periodontal status), operating method, and postoperative treatment. The age of the patient also has some influence on healing.
