Abstract

The successful outcome of the treatment depends upon good apical seal which will prevent microleakage. The goal of this study was to assess the addition of chitosan nanoparticles to Bioceramic sealer's apical sealing capacity. A total of 20 single rooted single canal teeth were used. The root canals were prepared using rotary files up to #30/.06 and irrigated with 2.5% NaOCl and normal saline. Samples were divided into 2 groups. Group I was obturated with gutta-percha using Bioceramic sealer and Group II was obturated with gutta-percha using Bioceramic-Chitosan-nanoparticles sealer. All samples were immersed in methylene blue 2% solution. The specimens were sectioned, observed under stereomicroscope and the dye leakage was measured. The data were analysed. The results of Unpaired t-test/Independent samples t-test showed that mean microleakage is significantly lower in group II as compared to group I. This study concludes that Chitosan nanoparticles incorporation improves the efficacy of Bioceramic sealer.
