The bonding of dental restorative materials to tooth structure has been the focus of dental research for many years. Resin cements are commonly used as luting cements for indirect esthetic restorations. Placing a temporary restoration after the tooth preparation is always necessary. Zinc oxide eugenol cements are the commonly used temporary materials. It is a known fact that eugenol inhibits polymerization of composite. The exposure of enamel to the temporary cement/filling material containing eugenol will not have any effect on the shear bond strength of a dual curing luting resin to enamel, if acid etching is performed. Hounsfield universal Testing Machine is used to record the shear bond strength values of composite to enamel.
