Nonsurgical Treatment Outcomes and Prognostic Factors for Cases with Lesions of Endodontic Origin in a Private Practice

Abstract

Aim: The prognosis of the healing of an apical lesion is extremely important for the treatment decision for tooth retention or implantation. In several studies, the presence of an apical lesion was shown to be a significant factor in both primary treatment and non-surgical retreatment. The aim of the present study was the retrospective investigation of the prognosis of the healing of bony apical lesions of teeth, which were treated endodontically. The evaluation contained various clinical parameters that can influence the success of the root canal treatment. Materials and Method: 62 teeth were treated in 52 patients during the study period. The treatment was carried out by a specialist in endodontics with the aid of the dental surgical microscope and a two-stage procedure. Two certified examiners assessed the radiological results after three to 72 months. Preoperative and postoperative information related to potential prognostic factors was evaluated. Results: Results of the 62 apical lesions, 82.3% (examiner 1) - 88.75% (examiner 2) were classified as healed. Of all the prognostic factors analyzed, none showed a significant influence on the treatment success. The success rate of the present study was in the range of comparable studies. Conclusions: The apical lesion can be treated with relatively high success rates if general micro-endodontic procedures are followed.
