Abstract
Successful root canal therapy also depends on an apical seal that further inhibits microbial re-infection in addition to biomechanical debridement. Therefore, it is of interest to evaluate bioceramic root canal sealer (Bioroot RCS) push-out bond strength difference using various intracanal final irrigants. The apical portion of 75 extracted mandibular premolars were enlarged till a size of 30.4% and segregated into five groups based on the final irrigant as Group 1-10% Citric acid, Group2-0.2% Chitosan, Group 3-0.1% Octenidine dihydrochloride, Group 4-17% Ethylenediamine tetra acetic acid and Group 5-distilled water (control group). 3mm sample sections were obtained from the coronal third of the specimens following obturation using Bioroot RCS sealer and gutta-percha and further push out bond strength was evaluated. The various mode of failure (Adhesive, Cohesive, Mixed) were observed under a stereomicroscope of 20X magnification following the test. Thus, we show that 10% citric acid when used as the final irrigant can enhance the bond of the bioceramic sealer (Bioroot RCS) with the radicular dentin which may lead to a favourable endodontic outcome.
