ABSTRACT

Objective: The advancement and consistent application of adhesive materials are transforming various facets of restorative and preventive dentistry. Hence; the present study was conducted for evaluating the efficacy of various root canal Irrigants on Microtensile Bond Strength of Adhesive Systems to Dentin. Material and methods:Assessment of 40 freshly extracted maxillary second premolars were included in the present study. Randomized division of all the specimens was done into four study groups with ten specimens in each group as follows:Group A: Specimens treated with sodium hypochlorite (NaOCl),Group B: Specimens treated with chlorhexidine (CHX),Group C: Specimens treated with NaOCl + sodium ascorbate, and Group D: Control group- Specimens treated with distilled water. Resin composites were utilized in conjunction with a universal adhesive system, and the micro-tensile bond strength was evaluated through a universal testing machine. The resulting data were analysed using SPSS software to ascertain the outcomes related to bond strength. Results:A total of 40 tooth specimens were included. Mean micro-tensile bond strength among specimens of Group A, Group B, Group C and Group D was 56.9 N, 45.1 N, 92.7 N and 43.8 N respectively. Significant results were obtained while comparing the micro-tensile bond strength among specimens of all the four study groups. Greatest strength was exhibited by specimens irrigated with NaOCl + sodium ascorbate. Conclusion:Various irrigants exhibited distinct impacts on the bonding efficacy of different adhesive systems. The application of sodium ascorbate following sodium hypochlorite treatment demonstrated the potential to reinstate diminished bond strengths.
