Efficacy and retrievability of root canal filling using calcium silicate-based and epoxy resin-based root canal sealers with matched obturation techniques

This study aimed to compare the efficiency of root canal filling procedures and the retrievability of the filling material with various sealers. Forty-three patients assigned to endodontic treatment with (i) continuous wave of condensation technique (CTW) with AH-plus (ii) single-cone technique (SCT) with EndoSeal MTA. The spent time, voids entrapping and postoperative symptoms were evaluated. To evaluate the retrievability, mandibular premolar (n = 60) were divided into four groups: AH-plus/CTW, EndoSeal MTA/SCT, MTA Fillapex/SCT and EndoSequence BC Sealer/SCT. The time required removing the filled materials and remnant score were examined. EndoSeal MTA/SCT showed significantly shorter time of filling procedure. The number of void did not show significant differences between two techniques. No patients showed clinical signs during the follow-up periods. There were no significant differences between group AH-plus and EndoSeal MTA for remnant score. A certain calcium silicate-based sealer with SCT may give similar clinical efficiencies as much as continuous-wave technique using AH-plus sealer.
