N2 - Introduction: The purpose of this study was to evaluate the push-out bond strengths of different obturating materials. Methods: Forty single-rooted human extracted teeth were used in this study. The teeth were instrumented and irrigated by using 5.25% NaOCl, 15% ethylenediaminetetraacetic acid, and sterile water. The teeth were then filled with Resilon/RealSeal, Resilon/RealSeal SE, Resilon/MetaSeal, or gutta-percha/Kerr EWT sealer. The roots were then sectioned into 1-mm-thick slices and subjected to vertical loading to displace the obturating material toward the coronal side of the slice. The bond strength was then calculated and subjected to statistical analysis. Slices were examined by using a stereomicroscope at 30× to determine the mode of failure. Results: The mean push-out bond strengths were as follows: Resilon/RealSeal, 1.45 ± 0.99 MPa; RealSeal SE, 0.88 ± 0.49 MPa; Resilon/MetaSeal, 2.41 ± 1.7 MPa; and gutta-percha/Kerr EWT sealer, 2.32 ± 0.74 MPa. Conclusions: The push-out bond strengths of Resilon/MetaSeal and gutta-percha/Kerr EWT were significantly (P < .05) higher than either Resilon/RealSeal or Resilon/RealSeal SE. Resilon/MetaSeal and gutta-percha/Kerr EWT did not differ significantly.
