EVALUATION OF INTERFACE CHARACTERISTICS WITH DENTIN OF CALCIUM SILICATE ROOT CANAL SEALER: AN IN VITRO STUDY
Main Article Content
Abstract
Calcium silicate cement has the ability to release calcium hydroxide, which, upon contact with phosphate from dentin fluid, it forms an interface layer between the cement and the dentin. This creates a chemical bond between the cement and the dentinal walls of the root canal, thereby enhancing the complete sealing of the canal system. Therefore, the current study aims to evaluate the interface characteristics with dentin of two types of calcium silicate cements, either self-mixed BiorootTM RCS or pre-mixed CeraSeal. Objective: To identify marginal gaps and describe the interface characteristic between the two types of calcium silicate cements and dentin in the apical region after 90 days of simulated body fluid test (SBF) using scanning electron microscopy (SEM). Subjects and Methods: Mandibular premolar teeth were prepared and root canals were filled with cement BiorootTM RCS and CeraSeal, immersed in SBF solution for 90 days, then cross-sectioned at the root apex and observed under a scanning electron microscope. Results: There was the formation of an interface layer with the dentin that was more radiopaque and morphologically different from both the cement and dentin in both groups of teeth filled with cement BiorootTM RCS and CeraSeal. Conclusion: Both types of calcium silicate-based cements provide adequate root canal sealing quality. The formation of an interface layer with dentin helps reduce marginal gaps and enhances the material's adhesion to the tooth structure.
