%X Introduction: The aim of this study was to evaluate in vitro the bonding of AH Plus and Endofill sealers to intraradicular canal walls after different dentin surface treatments. Material and methods: Sixty canines were sectioned obtaining dentin discs with 4-mm thickness and were embedded in acrylic resin. The canals were prepared with diamond burs. The specimens were divided into two groups(n = 30): GI 每 AH Plus and GII 每 Endofill and were subdivided into three groups based on the dentin surface treatment (n = 10): A 每 distilled and deionized water (control), B 每 17% EDTA, C 每 CO2 laser with 3W in continuous mode for 10s. The specimens were submitted to push out test in a universal testing machine. Results: Tukey test revealed that the IB (AH Plus/17% EDTA) (17.59 ㊣ 6.04) and IC (AH Plus/CO2 laser) (21.69 ㊣ 4.93) subgroups had the highest values, which were statistically similar between each other (p > 0.05) and different from the other subgroups (p < 0.05). IIC subgroup (Endofill/CO2 laser)(7.25 ㊣ 1.59) had intermediate values, which were statistically similar to (p > 0.05) IA subgroup (AH Plus/water) (10.99 ㊣ 2.63), IIA subgroup Endofill/water) (3.16 ㊣ 0.83) and IIB subgroup (Endofill/ 17% EDTA)(5.31 ㊣ 3.61), which had the smallest values (p < 0.05). Conclusion: The treatment of superficial intracanal dentin with CO2 laser and EDTA favored the adhesion of AH Plus and Endofill sealers.
