Abstract

Aim To compare the efficacy of rotary and two reciprocating techniques during the removal of epoxy resin based sealers from root canals Methodology Thirty six root canals of extracted single-rooted human maxillary premolars were shaped with ProTaper Next (PTN) up to X3 (Dentsply Sirona, Switzerland) and filled with gutta-percha points and an epoxy-resin based sealer (AH Plus, Dentsply DeTrey, Germany) using the lateral compaction tech- nique. After two weeks, the samples were randomly distributed into three groups (n = 12) according to the retreatment technique used: Group 1: ProTaper Universal retreatment system and addi- tional PTN instruments up to size 40, .06 taper ; Group 2: Reciproc instrument size 40, .06 taper (VDW, Germany) ; Group 3: Reciproc Blue instrument size 40, .06 taper (VDW). The retreatment tech- niques were used according to the manufacturers’ instructions. After the retreatment procedure, the root canals were irrigated with 1 mL 2.5% NaOCl, then filled with 1 mL 15% EDTA, left in canal for 3 min, and finally rinsed with 1 mL 2.5% NaOCl. The samples were scanned in a micro-computed tomographic (micro- CT) device after root canal filling and after the retreatment proce- dure. The results were analysed with Kruskal–Wallis and post-hoc Mann–Whitney U test at level of significance set at 0.05. Results There was a significant reduction in the volume of root filling after all retreatment techniques (p < 0.05). The Reciproc technique had the largest reduction in the volume of the filling compared to the ProTaper Universal (p = 0.09) and the Reciproc Blue (p = 0.016). There were no significant difference between ProTaper and Reciproc Blue (p = 0.465). Conclusions The Reciproc was the most effective technique in the removal of epoxy resin based sealer from root canal compared to Reciproc Blue and the rotary ProTaper technique.
