Abstract

Objective: The purpose of the present study was to evaluate flow, film thickness, working time, setting time, dimensional change, sorption, solubility and cytotoxicity of an experimental epoxy-based root canal sealer with addition of bismuth subnitrate in different concentrations. Methods: Endodontic sealers were prepared with an epoxy resin with bismuth subnitrate additions of 20%, 40%, 60%, 80%, 100% and 120%. Flow, film thickness, working time, setting time, dimensional change, sorption, solubility, and cytotoxicity were studied according to ISO standards. Data were analyzed by one-way ANOVA and Tukey. Results: The flow, working time, water sorption, and solubility significantly decreased with increasing filler particle concentration. The film thickness and dimensional change values significantly increased with higher filler particle addition. There was no difference in the results of setting time and cytotoxicity comparing the groups. Conclusion: Addition of bismuth subnitrate appears to be a promising filler particle for root canal sealer.
