Objective: The purpose of this study was to develop a tensile bond strength test design for resin composites with a more uniform stress distribution using a circular dumb-bell form. In addition, the effectiveness of various surface treatments used to enhance the bond strength of composite resins to resin based composite (RBC) luting cements was evaluated. Method: Seventy two semi-dumb-bell shaped buttons were made in composite and bonded onto Ni-Cr rods. These half specimens were subjected to various surface treatments [Sand papering (SP), Sand papering + Silane (SP + S), Sand papering + Modified Silane (SP + Mod.S), Cojet (CJ), Cojet + Silane (CJ + S)] and bonded by dual cured resin cement (Variolink II). This arrangement was mounted on a special three-point grip clamp and tested for tensile bond strength. The debonded surfaces were examined under an optical microscope for the mode of failure. One-way ANOVA and Tukey’s pairwise test were used to determine significant difference between the groups. Results: SP gave the highest bond strength (29.41 MPa) while SP + Mod.S gave the lowest bond strength (22.63 MPa). There was a significant difference between the bond strengths of SP and SP + S, SP + Mod. S and CJ; and also between CJ + S and SP + Mod.S. The mode of failure for all surface treatments was adhesive, involving only one interface. Conclusions: A tensile bond strength test method was developed using the circular dumb-bell-form. Silane application reduced the bond strength after sand papering while it increased the bond strength after siilicatization. The bonding interface, irrespective of the surface treatment, was the weakest link in the resin-to-resin adhesive complex.
