Objective: The aim of this in vitro study was to evaluate the effect of addition of various surface-modifying agents to EDTA solution on the bond strength of an epoxy-based sealer to the root canal dentin. Materials and Method: Sixty single-rooted human mandibular premolars were decoronated and instrumented using rotary system. The specimens were then randomly divided into four groups (n=15) according to irrigation with different EDTA solution (Wizard, Rehber Kimya, Istanbul, Turkey) combinations as follows: Group 1: 17% EDTA + 0.1% benzalkonium chloride; Group 2: 17% EDTA + 0.1% Tween 80; Group 3: 17% EDTA + 0.1% Triton X-100 and control group: 17% EDTA without any surface-modifying agents. Surface tensions of the EDTA solutions were controlled with a tensiometer. Final irrigation was with 5 mL of 5% sodium hypochlorite (Wizard) for 1 min, followed by 5 mL of the mentioned EDTA solution for another minute. Roots were obturated with gutta-percha and AH Plus sealer (Dentsply DeTrey, Konstanz, Germany) using cold lateral compaction technique. Horizontal root sections were obtained, and push-out test was used to measure the bond strength between the root canal dentin and sealer. Data were analyzed using the two-way analysis of variance and post hoc Tukey tests (p
