Comparative evaluation of physical properties of resin and calcium silicate-based root canal sealers

Abstract

Aim: The aim of this study was to evaluate the flow, solubility, and pH of AH Plus sealer, Bio-C Sealer, and Cerafill RCS. Methods: The selected sealer materials were mixed according to instructions of the manufacturers under aseptic conditions. For flow and solubility, the recommendations of ISO 6876/2012 and ANSI/ADA 2000 standards were followed (n = 10). Additionally, pH changes during the setting of selected sealers (n = 10) were measured at regular intervals of time using a digital pH meter. Data were statistically analyzed using Kruskal-Wallis ANOVA test with post hoc Dunn's test. Results: The flow of Bio-C Sealer was significantly higher than Cerafill RCS (P < 0.05). Among the sealers, Bio-C Sealer exhibited the highest solubility, whereas AH Plus exhibited the least solubility. Calcium silicate-based sealers showed higher pH than resin-based sealer. Conclusion: The results of the present study indicate that resin-based sealer and calcium silicate-based sealers have acceptable flow, whereas calcium silicate sealers exhibited high solubility and an alkaline pH.
