Evaluation of microsurgery with supereba as root-end filling material for treating post-treatment endodontic disease: A 2-year retrospective study

摘要

Introduction This retrospective study assessed the effects of microsurgical treatment of post-treatment endodontic disease using SuperEBA (Bosworth, Skokie, IL) as the root-end filling material and evaluated the potential prognostic factors in relation to outcome. Methods Data were collected from patients diagnosed with post-treatment endodontic disease who then underwent endodontic microsurgery between April 2007 and October 2010. The effect was evaluated 2 years after the operation. Surgical procedures were performed by a single endodontic specialist. After surgery, operation records were recorded including preoperative, intraoperative, and postoperative factors from the clinical and radiographic measures. For statistical analysis of the predisposing factors, the dependent variable was the dichotomous outcome (ie, success vs failure). Results Eighty-two patients with 101 treated teeth met the inclusion criteria. The recall rate was 87.2%. Of these microsurgically treated cases, the overall healing rate was 93.1%. At the 0.05 significance level, age, sex, tooth position, size of periapical radiolucency, biopsy result of periapical lesion, and presence of a sinus tract appeared to have no significant effects on the outcome (P >.05). Conclusions Microsurgical endodontic treatment using SuperEBA as the root-end filling material is a favorable option for post-treatment endodontic disease.
