RESUMO
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.

Autotransplantation of teeth has been performed for many years and with varying degrees of success. The present report concerns the long-term results of autotransplantation of 36 teeth with completed root formation. Endodontic treatment was started before or within 12 weeks after transplantation. At the final check-up 32 teeth were present, 24 of them without signs of inflammation, replacement, or internal resorption. Careful radiographic examination during the follow-up period and adequate therapeutic measures with inter alia renewed endodontic treatment are of importance for successful autotransplantation.
