Introduction: This retrospective study evaluated cases of unintentional overfillings for the fate of the extruded sealers and their influence on treatment outcome. Methods: One hundred five teeth treated by a single operator and exhibiting overfillings in the postobturation radiograph were included in the study. Seventy-five teeth exhibited apical periodontitis lesions at the time of treatment.
Recall radiographs were compared with immediate postobturation films for removal of the extruded material and status of the periradicular tissues. No other significant differences were observed between groups. Conclusions: Not all extruded sealers were predictably removed from the periradicular tissues. Treatment outcome was not significantly affected by the type of extruded sealer. A significantly better outcome was observed for teeth with no lesion in comparison with teeth with apical periodontitis.
