Summary

This prospective, randomized, single-center, single-blind clinical trial evaluated the effects of different nickel-titanium retreatment and final shaping systems on postoperative pain and operation time during single-visit nonsurgical endodontic retreatment of mandibular first molars. Participants were allocated to four groups according to the combination of the retreatment system used for root canal filling removal and the rotary or reciprocating system used for final root canal shaping. Postoperative pain, analgesic consumption, and operation time were assessed and compared among the groups.
