Bond strength of dentin bonding agents may depend on the choice of the restorative materials. It is common in clinical practice to use a composite resin of one manufacturer and adhesive of another. The purpose of this study was to evaluate whether any variations in bond strength occurred when this was done. Shear bond analysis was done for seven groups. Three groups, in which manufactures recommendations were followed and four groups when a combination of products was used. The result showed that higher shear bond values are achieved when the manufacturers recommendations are followed.
