ABSTRACT
This in vitro investigation compares the shear bond strength of two systems that can be used to bond gold alloys to dentine. In the first group, sandblasted gold alloy surfaces were tin-plated and bonded to dentine using C&B-Metabond, an adhesive resin cement. In the second group sandblasted gold alloy surfaces were silicoated (Kulzer) and bonded to dentine using Denthesive II, Adhesive Bond II and Twinlook cement. Forty eight hours after bonding the bonds were stressed to failure in the sheer mode in an Instron testing machine. All data were statistically analysed (Student-t-test). The results in MPa were Tin-plated gold to dentine 18.23; silicoated gold to dentine 10.35. C&B-Metabond demonstrated a statistically significantly higher bond strength (p < 0.01). It can be concluded that tin-plating in conjunction with C&B-Metabond produces a stronger bond than silicoating in conjunction with Denthesive II and Twinlook cement when used to bond gold alloys to dentine.
