Comparison of shear bond strength of metal castings luted to dentine using resin cements

ABSTRACT

The purpose of this study was to investigate the shear bond strength of metal discs luted to dentine. In this study three resin luting cements i.e. Panavia F [Group I], Variolink II [Group II] and Superbond C and B [Group III] were compared to demonstrate which material was more superior to bond sandblasted cobalt chromium alloy to dentine. Groups I, II and III were compared using ANOVA, P < 0.05. Panavia F demonstrated significantly higher bond strengths than Variolink II or SuperBond C and B. SuperBond C and B had significantly higher shear bond strength than Variolink II. Thus, there were significant differences among the tested resin luting cements for bonding metal discs. Panavia F was found to give the highest shear bond strength within the limitations of this study followed by Superbond C and B and Variolink II
