- Introduction: The aim of this study was to evaluate and compare the efficacy of various irrigating solutions on smear layer removal and dentin microhardness. Material & Method: 50 single rooted teeth were equally divided in two halves to evaluate smear layer removal and measure dentin microhardness. The teeth were randomly divided into 5 groups (n=10) based on the final irrigant used (Group 1: 17% EDTA, Group 2: 7% Maleic Acid,Group 3 10% Maleic Acid, Group 4: MTAD, Group 5: Saline (Control). Chemomechanical preparation was performed with a step back technique using K files. The half roots from each group were prepared for SEM to evaluate the smear layer in coronal, middle and apical thirds and the other halves were prepared to measure the dentin microhardness. Statistical Analysis: Statistical comparison was done by Kruskal Wallis One way ANOVA along with Post HOC Tukey HSD test with a significance level of 0.05. Result: The smear layer removal efficacy was comparable for all irrigants at coronal and middle one third regions. Apical one third region showed MTAD and 10% Maleic Acid to be most effective followed by 7% Maleic acid then 17% EDTA. The dentin microhardness was most affected by MTAD and 10% Maleic acid followed by 17% EDTA and least affected by 7% Maleic acid. Conclusion: 7% Maleic acid proved to be quite effective in smear layer with least affect on dentin microhardness.
