Aim: The purpose of this study was to evaluate the effect of 17% ethylenediaminetetraacetic acid (EDTA) and 0.2% chitosan on pushout bond strength of biodentine and ProRoot mineral trioxide aggregate (MTA). Materials and Methods: Midroot dentin of single-rooted human canine teeth were sectioned into 2-mm-thick slices horizontally (n = 60). The canal space of each dentin slice was enlarged with a 1.3-mm-diameter diamond bur. The samples were divided into two groups (n = 30) based on the type of perforation repair material placed, i.e., Biodentine and ProRoot MTA. The samples were wrapped in wet gauge for 10 min, and based on the type of chelating agent used for removal of smear layer, each group is further divided into three subgroups (n = 10), to be immersed into saline (control), 17% EDTA and 0.2% chitosan for 30 min, and a wet cotton pellet was placed over each test material. After 48 h of incubation, the dislodgement resistance of the samples was measured using a universal testing machine. Statistical Analysis: Data were analyzed using one-way analysis of variance and post hoc Tukey tests. The level of statistical significance was set at 0.05. Results: Biodentine showed significantly higher pushout bond strength than ProRoot MTA. Biodentine and ProRoot MTA lost strength when exposed to 0.2% chitosan. Conclusion: Biodentine showed considerable performance as a perforation repair material than ProRoot MTA even after being exposed to various endodontic chelating agents.
