Objective: The objective was to evaluate and compare coronal microleakage of two different adhesive restorative cements placed in pulp chamber following different irrigant regimens by using polymicrobial marker.
Materials and Methods: Access opening of 60 single rooted teeth was done. Cleaning and shaping was done in a step down procedure using irrigation regimen for thirty samples as sodium hypochlorite and tublicid plus and other group with sodium hypochlorite and EDTA. All samples were sectioned horizontally1mm below the orifice and each group was again subdivided into two subgroups and restored with nano-composite and nano-glass-inomer cement and were artificially aged by thermocycling. Microleakage was evaluated by placing samples in a split chamber model and observed for turbidity in the lower chamber for a period of 90 days.
Results: Kruskal-Wallis one way ANOVA test and Chi-square test was done to statistically assess the effect of final irrigants on sealing ability of these restorative materials. It was found that there was no significant difference among the four groups.
Conclusion: Samples irrigated with tublicid plus and restored with nanocomposites showed better sealing ability than other three groups.
