Thin resin coating by dual-application of all-in-one adhesives improves dentin bond strength of resin cements for indirect restorations.
This study was evaluated the tensile bond strength (TBS) of resin cements to bovine dentin resin-coated with all-in-one adhesive systems. Each of the dual-polymerizing resin cements; Link Max, Clearfil Esthetic Cement, Bistite II and Chemiace II were used to bond indirect resin disks to bovine dentin, as control, or coated by single-application or by dual-application of an adhesive system from the same manufacturer; G-Bond, Clearfil Tri-S Bond, Tokuyama Bond Force and Hybrid-Coat (n=10). After 24-hour water storage, TBSs were measured. The fracture pattern and the adhesive interface were observed using an SEM. Dual-application of the adhesive yielded significantly higher TBSs compared to control and single-application groups for all materials (p<0.001). From the limited information of this study, it was concluded that dual-application of all-in-one adhesive systems created a thin coating on dentin, and significantly improved the bond strengths of resin cements.
