Abstract
The purpose of this study was to evaluate failure factors of endodontic treatment in patients who needed endodontic retreatment owing to treatment failure. In total, 117 consecutive patients (132 teeth) requiring endodontic retreatment were enrolled. Two researchers examined preoperative periapical radiographs to assess whether they were “adequate root canal filling” or “inadequate root canal filling”. Failure factors were searched through clinical chart and periapical radiograph. 75% of patients who need endodontic retreatment had an inadequate root canal filling. Within the limitation of this study, quality of root canal filling could be an important failure factor in patients requiring endodontic retreatment, and clinicians need to make an effort for adequate quality of root canal filling.
