Background and Aim: To evaluate the bond strength of MTAFillapex to dentin in various regions of the root canal afterfilling with carrier-based heated gutta-percha/resilon and tocompare it with iRoot SP.Materials and Method: Forty single-rooted extracted humantooth root canals were biomechanically prepared. The sampleswere randomized into four experimental groups (n = 10).Root canal obturations were performed using the core carriersystems as follows:Group 1: MTA Fillapex + GT ObturatorGroup 2: MTA Fillapex + RealSeal 1Group 3: iRoot SP + GT ObturatorGroup 4: iRoot SP + RealSeal 1For the push-out test, 2-mm horizontal sections from theapical, middle, and coronal parts of the root were prepared.The sections were then subjected to a push-out test using auniversal testing machine, carrying different sizes of plungersaccording to the region of the root. The loading was performedfrom the apical to the coronal direction until bond failureoccurred. The maximum load value was recorded in Newton andthen converted to megapascals considering the cross-sectionalarea. The data were analyzed statistically by Kruskal–Wallis testwith multiple comparisons. The level of significance was set at5% for all tests.Results: The samples in Group 3 showed the highest bondstrength values, and the difference was statistically significantcompared with the other groups at all levels (p < 0.05).Conclusions: In conjunction with the GT obturator core carriersystem, iRoot SP showed the
