Objective: To evaluate the influence of prior acid-etching to the microshear bond strength of two commercial two-step self-etching adhesive system. Methods: Thirty-two bovine lower incisive were divided into four groups. ClearFill SE Bond and AdheSE were used. Prior acid etching was applied in the half of the teeth. On the other half of the adhesive system were applied according manufacturer. Six cylindrical restorations were produced in each tooth, with adhesive area of 0.88 (± 0.03) mm2. After 24 hours of restoration procedure, the restoration was submitted to a microshear bond strength test with a cross-head speed of 1 mm/min. Data were analyzed with one-way ANOVA (adhesive system and prior acid etching), with 5% of statistical significance level. Results: The average bond strength values of all groups ranged from 16,25 to 21,71 MPa. However, no statistical difference were detected among all groups, regardless of clinical procedure (p>0.05). Conclusion: The prior acid etching of the dentin did not affect he immediate bond strength of the two commercial two-step self-etching adhesive system.
