title: The effect of various surface treatments on the shear strength between composite resin and glass-ionomer cement.
abstract: The effect of various surface treatments on the shear bond strength of composite resin to a glass-ionomer cement has been studied. Acid etching with phosphoric acid and polyacrylic acid, roughening by way of grinding or air drying, the use of a dentine bonding system and a silane coupling agent were the variables. Acid etching, grinding or air drying the surface of the cement had a significant effect on the bond strength. The use of a dentine bonding system led to a significant improvement in the resulting bonding. Silane coupling agent did not improve the bonding. Composite resin did not adhere to a smooth cement surface, but the application of the dentine bonding system on such a surface produced a moderate bond.
