Retreatability of root canals obturated using mineral trioxide aggregate-based and two resin-based sealers.

Background: The aim of this study was to compare the retreatment time and the removal efficiency of different root canal sealers using WaveOne Gold reciproc file system by measuring required time.

Materials And Methods: Forty-five mandibular premolars were prepared and randomly divided into three groups (n = 15). In Groups 1-3, the canals were filled with gutta-percha and mineral trioxide aggregate (MTA) Fillapex, EndoREZ, and AH26, respectively.
