Purpose: The purpose of this study was to evaluate the influence of prophylactic paste containing fluoride on the enamel bond strength of single-step self-etch adhesives. Methods: Three adhesives, BeautiBond, Bond Force and G-Bond Plus, were used in this study. The enamel surfaces were treated with fluoride paste for 30 s twice a day. After 10 minutes (immediate group) and 7 days of treatments, bond strength specimens were made using each adhesive. Specimens were stored in 37℃ distilled water for 24 h, and then subjected to a shear bond strength test in a universal testing machine at a crosshead speed of 1.0 mm/min. Results: In the immediate group, the bond strengths of the enamel surface treated with fluoride paste, no significant differences were observed in all the adhesives, compared with the baseline. However, in prophylactic paste, the bond strengths were different, depending on the adhesives. On the other hand, in the 7-day group, the bond strengths were significantly lower in both pastes. After the bond strength test, the dominant failure mode was adhesive failure. Conclusion: The enamel bond strengths of the single-step self-etch adhesives were adversary affected by the use of prophylactic paste containing fluoride.
