OBJECTIVE: The purpose of the present study was to evaluate the relationship between apical and marginal periodontal healing after periapical surgery. STUDY DESIGN: The investigation was conducted on 59 patients referred for periradicular surgery. A radiographic examination as well as assessments of periodontal attachment and pocket depth of teeth undergoing surgery and control teeth were performed at the time of surgery and 1 year after surgery. The radiographic periapical healing pattern was evaluated. RESULTS: After an observation time of 1 year, 85% of the healing patterns were classified as successful or uncertain. Teeth within the surgical area showed a significant loss of clinical attachment during the observation period. The mean clinical attachment loss in teeth with an unsuccessful healing was 0.85 mm and differed significantly from successfully healed cases (mean, 0.15 mm). CONCLUSIONS: A persisting endodontic infection may be regarded as a contributing risk factor for a progressing marginal attachment loss.
