Abstract
Introduction: The effectiveness of root canal therapy in endodontic practice is largely determined by achieving a compact fluid-tight closure at the apical end of the root canal, which inhibits irritant entry and buildup, which leads to a biological breakdown of the attachment mechanism and failure. During obturation, root canal sealers are used in conjunction with gutta percha to fill voids and seal root canals. Root canal sealers come in a variety of shapes and sizes, each with its own set. Aim: Biocompatibility was tested on animal models, and sealing ability was assessed using Scanning Electronic Microscope. Materials &methods: This study utilized two Bioceramic sealers (BioRoot RCS and Meta Biomed bio_ ceramic sealer (CeraSeal RCS) and compared the findings to a control of Zinc oxide eugenol sealer. Biocompatibility was determined by examining histopathological biopsy specimens collected from rabbits. Each rabbit had four dentin tubes implanted into the subcutaneous tissues, one for BioRoot RCS, one for CeraSeal RCS, and one for ZOE RCS, with the fourth tube being empty. Histological sections were stained with haematoxylin and eosin and assessed with light microscope. Extracted human single canal premolars were used to test the sealing ability. The root canals were divided into 3 sections (coronal, middle, and apical). SEM was used to assess the adhesion quality at the sealer-dentin interface. Results: BioRoot and CeraSeal sealers have excellent sealing adaptation and biocompatibility, as well as rapid tissue recovery, while ZOE sealers have a slower recovery of inflammatory reaction results when compared to bioroot and ceraseal sealers, as well as less sealing adaptation than the two other bioceramic sealers. Conclusion: In general, all sealers tested were biocompatible and capable of sealing or adhesion.
