title: Incomplete healing (scar tissue) after periapical surgery--radiographic findings 8 to 12 years after treatment.
abstract: Twenty-four cases treated by periapical surgery--which 2 to 6 yr after surgery were classified radiographically as incomplete healings (scar tissue)--were further followed, extending the observation period to 8 to 12 yr. One case healed completely, 1 failed, and 22 were still recorded in the same healing group. All the 22 scar tissue cases were characterized by a reduction of the defect in bone. In 13 cases, continuous periodontal structures were seen and the defect thereby separated from the root. The findings support the conclusion that cases clearly showing features of incomplete healing (scar tissue) at the regular follow-up 1 yr after surgery can be regarded as successes. They need not be recorded for further systematic control. A general follow-up program for apicectomy cases is suggested.
