Descrição: dc.descriptionObjective: To evaluate the influence of different luting protocols on the push-out bond strength of fiber posts cemented to bovine root dentin. Method: Forty bovine root canals (length: 16 mm) were prepared up to 12 mm using #3 (RTD) preparation burs. Each canal had its apical 4 mm embedded in acrylic resin and the roots were assigned to four groups (n=10), according to the cementation procedures: G1: etch-and-rinse multi-bottle adhesive system + #3 fiber post; G2: etch-and-rinse multibottle adhesive system + #1 fiber post; G3: etch-and-rinse multi-bottle adhesive system + #1 fiber post + accessory fiber posts; G4: #3 fiber post without etching and bonding procedures to dentin. Except for G4, root dentin was treated with the etch-and-rinse multi-bottle adhesive system All Bond 2 (Bisco). The adhesive system was applied with a microbrush (Dentsply) and excess material was removed with absorbent paper points. The quartz fiber posts (Macro-Lock Illusion/RTD) were cemented to the root dentin with a dual-cure resin cement (Duolink/Bisco) and were stored in distilled water (for 24 h at 37 °C) before the mechanical tests. Each sample was cut into four slices (1.8 mm thick) that were subjected to push-out tests in a universal testing machine (1 mm/min). The data (in MPa) were analyzed statistically by one-way ANOVA. Results: The mean push-out bond strength values (±SD) were: G1: 5.4 ± 1.3 MPa; G2: 4.2 ± 2.4 MPa; G3: 4.6 ± 1.5 MPa and G4: 3.3 ± 1.7 MPa. One-way ANOVA showed no statistically significant differences among the groups. The tested hypothesis was discarded. Conclusion: The push-out bond strength of fiber posts to root dentin was not influenced by the evaluated luting protocols.-
