Purpose: The aim of this study was to evaluate the outcomes of endodontic microsurgery and compare the healing success of the isolated endodontic lesion with the endo-perio combined lesions

N = 263 teeth


•227 patients requiring periradicular surgery were included in this study.  •Excluded cases with G > 2 mobility, HRF, VRF, perforations

•All patients were placed on an AB and analgesic regimen preoperatively  •Surgery performed under microscope, 3 root-end filling used randomly: IRM, SuperEBA, and MTA.

•Patients were recalled every 6 months for 2 years and every year thereafter to assess clinical and radiographic signs of healing. 

•A recall rate of 73% (192 of 263 patients) was obtained.

Most highlighted Results:

  •The successful outcome for isolated endodontic lesions was 95.2%.

•In endodontic-periodontal combined lesions, successful outcome was 77.5%, suggesting that lesion type (ABC vs DEF) had a strong effect on tissue and bone healing.

•Successful outcomes were seen with all 3 filling materials: 88.9% with IRM, 91.7% with SuperEBA and 91.5% with MTA.
