Comparison sealability of root canal obturation using bioceramic sealer and methacrylate resin-based sealer

Abstract

This study aimed to compare and analyze the obturation sealability using bioceramic sealer and methacrylate resin-based sealer. A total of 30 single-rooted teeth were prepared using ProTaper Next and randomly divided into two groups; the first group was obturated with bioceramic sealer (SB), while the second was obturated with methacrylate resin-based sealer (MRS). Coated gutta-percha was used as obturating material in both groups. Apical third marginal adaptation was evaluated by observing the dye penetration between the obturation material and the root canal walls on cross-sectioned samples. BS showed less microleakage in the apical third marginal adaptation than MRS. Obturation of root canal using BS has better sealing ability than MRS at the apical third.
