title: Clinical outcome of endodontic microsurgery that uses EndoSequence BC root repair material as the root-end filling material.
abstract: BACKGROUND
  The purpose of this retrospective study was to determine the clinical and radiographic outcome of root-end surgery when EndoSequence BC Root Repair (ES-BCRR) was used as the root-end filling material and to identify any possible prognostic factors that may have affected the healing outcome.
  
  
  METHODS
  Clinical records and periapical radiographs were collected from patients who had undergone endodontic microsurgery between 2009 and 2013 in a private endodontic office and had a minimum 1-year follow-up. All surgical procedures were performed by a single endodontist. ES-BCRR was used as the root-end filling material in all cases. Outcome was categorized into healed, healing, and non-healing on the basis of clinical and radiographic findings. The healed and healing cases were pooled and considered as success, and non-healing cases were considered failure. For statistical analysis of the prognostic factors, the dependent variable was the dichotomous outcome (ie, success versus failure).
  
  
  RESULTS
  Ninety-four patients with 113 teeth met the inclusion criteria and were included in the study. The overall success rate was 92.0%. None of the prognostic factors, including age, sex, tooth position, size of periapical radiolucency, presence of a sinus tract, preoperative symptoms, and retreatment previous to surgery, appeared to have any significant effects on the outcome (P > .05).
  
  
  CONCLUSIONS
  This current study suggests that ES-BCRR is a suitable root-end filling material to be used in endodontic surgery.
