Abstract:
Introduction
The aim of this in vitro study was to evaluate the setting time, flow, film thickness, solubility, radiopacity and characterization analysis of three epoxy resin based sealers including two experimental sealers and AH-26.Methods and Materials: Five samples of each material were evaluated for setting time, flow, film thickness, solubility and radiopacity according to ISO 6876 Standard. Characterization of sealers was performed under the scanning electron microscopy (SEM), X-ray energy dispersive spectroscopy, X-ray diffraction (XRD) and Fourier transform infrared (FTIR) spectroscopy. Statistical evaluation was performed using the Kruskal-Wallis test.
Results
In this study, AH-26 showed more radiopacity and flow compared to two other experimental sealers (P0.05). The characterization analysis exhibited relatively similar microstructure of AH-26 sealer to the experimental root canal sealers.Conclusion
According to the result of this study, all tested root canal sealers had acceptable properties based on ISO 6876 standard criteria.Keywords:
