Purpose: To determine if bonding incompatibility between a single-step self-etching adhesive and a dual-cured luting cement is prevented by addition of deprotonizing anion exchange resin powder to the amine component of the resin cement. Materials and Methods: iBond adhesive (IBO) (Heraeus Kulzer) and the dual-cured resin cement Twinlook (TWI) (Heraeus Kulzer) were used with base pastes, containing 0, 1, 2, and 4 wt% anion exchange resin (AER) in OH-form. Conventional shear bond strength (SBS) was determined on human dentin. After application of IBO, a cylindrical mold was clamped on the treated surface and bulk filled with TWI. SBS was measured after 24 h in 37°C water at a crosshead speed of 1 mm/min. The following curing protocols were investigated: Group 1: IBO not light cured, TWI redox cured; group 2: IBO light cured, TWI redox-cured; group 3: IBO light cured, TWI dual cured (n = 8). The data were statistically analyzed using ANOVA and Duncan's post-hoc test at α < 0.05. Results: The mean SBSs (MPa) with original TWI in groups 1, 2, and 3 were 12.7aA, 16.4bA, and 24.7cA. The corresponding figures for 1% AER were: 16.6aB, 23.0bB, 22.8 bA; for 2% AER: 16.8aB, 22.6abB, 24.6 bA; and for 4% AER: 16.2aAB, 22.5bB, 24.7 bA. Different small and capital letters denote significant differences by treatment group and by AER content, respectively. Conclusion: Addition of anion exchange resin to the amine component of the dual-cured resin cement enhances the bond strength to dentin upon redox curing by prevention of amine neutralization through functional acid monomers from an all-in-one adhesive, mainly when the adhesive or the luting cement were not light cured.
