Effect of root canal sealers on the push-out bond strengths of tooth-colored posts to root dentine

摘要: Objectives: This study evaluated the effect of different root canal sealers on push-out bond strength tooth-colored posts to dentin. Material and methods: Eighty human mandibular premolar teeth with single roots were decoronated randomly divided into two groups according post material: G1–G5: Cytec blanco; G6–G10: Cosmopost. In each group, specimens further subgrouped filling material plus sealer (n = 8): G1, G6: Gutta-percha + AH Plus; G2, G7: Resilon + Epiphany SE; G3, G8: Gutta-percha + Sealite; G4, G9: Gutta-percha + iRoot SP; G5, G10: control (unobturated). blanco Cosmopost 1.4 mm diameter adhesively luted samples using Variolink II. Push-out test was performed in a universal testing machine, failure modes examined under stereomicroscope. Data analyzed two-way ANOVA hoc Tukey’s tests. Statistical significance set 0.05. Results: Roots obturated AH Plus (3.48 ± 1.41 MPa), Sealite (3.47 ± 0....
