Abstract

Objective: The purpose of this study was to investigate the effect of the incorporation of chitosan nanoparticles into epoxy resin-based sealer on its setting time, flowability and solubility.


Methods: This study was divided into three evaluations, namely setting time, flowability, and solubility of sealers. Each study used 20 samples, which were divided into two groups. Group 1, epoxy resin-based sealers, and group 2, epoxy resin-based sealers mixed with chitosan nanoparticles. The Gilmore needle was used to observe the setting time, a simple press method based on ISO 6876 was employed to evaluate the flowability of the sealer, and the solubility test, which was according to ISO 6876 standard was used to determine the solubility of sealers. The surface structure of the sealers before and after the solubility test was observed under Scanning Electron Microscopy (SEM).


Results: No significant difference occurred between epoxy resin-based sealer and epoxy resin-based sealer mixed with chitosan nanoparticles in terms of setting time, flowability, and solubility of sealers (*P > 0.05).


Conclusion: The incorporation of chitosan nanoparticles produced the same setting time, flowability, and solubility as the epoxy resin-based sealer. Thus, both sealers showed acceptable properties in terms of setting time, flowability, and solubility based on ISO 6876 standards.
