Aim: To evaluate the effect of 17% ethylenediaminetetraacetic acid (EDTA) and 7% maleic acid (MA) irrigation on microleakage of mineral trioxide aggregate (MTA) and Biodentine® (BD) when used as a root‑end filling material.Materials and Methods: Sixty human anterior teeth were decoronated and subjected to root canal instrumentation.3 mm of apical root portion was resected, and root‑end cavities were prepared using ultrasonic tips. Teeth were then randomly divided into two groups (n = 30). Group 1 ‑ root end cavity to be filled with MTA; Group 2 ‑ root end cavity to be filled with BD. Each group was further divided into three subgroups A, B, and C based on irrigation regimen. Group A ‑ 17% EDTA; Group B ‑ 7% MA; Group C ‑ 0.9% saline. About 5 mL of all irrigating solutions were used for 1 min. After final irrigation, root‑end cavities were filled with respective root end filling material. Specimens were then subjected to microleakage analysis at 24 h, 7 days and 14 days using glucose filtration technique. For smear layer evaluation, six central incisors were subjected to root canal instrumentation and irrigation with 7% MA and 17% EDTA. Then, these samples were analyzed under the standard error of the mean data was analyzed using one‑way ANOVA, Bonferroni test, Mann–Whitney U‑test and Kruskal–Wallis test.Results: Saline group demonstrated significant higher leakage than that of 17% EDTA and 7% MA in both MTA and BD groups. However, there was no significant difference between 17% EDTA and 7% MA group when MTA was used as root‑end filling material. In BD group, 17% EDTA showed more leakage than 7% MA.7% MA was able to remove the smear layer better than 17% EDTA.Conclusion: MTA had a better sealing ability as compared to that of BD when root‑end cavities were irrigated with 7% MA.
