Objective: The aim of this study was to evaluate postoperative pain after non-surgical root canal retreatment with or without GuttaClear.
Methods: Sixty participants were randomly distributed in this non-inferiority trial into two parallel singleblinded experimental groups (Group1: non-solvent, Group2: solvent). After root canal retreatment, the participants completed questionnaires using direct (numerical rating scales) and indirect (number of analgesics taken) measurements of postoperative pain at immediate, 6, 12, 24, 48, and 72 h post-retreatment.
