Adhesive strength between teeth and resin cements for porcelain laminate veneer.
We performed an experiment on adhesive strength between teeth and resin cements for porcelain laminate veneer. A compression shear test was performed using three types of resin cement in extracted human anterior teeth. In dentin, the effects of various surface treatment methods were also evaluated. All three types of resin cement showed high adhesive strengths to enamel, but low adhesive strengths to dentin that were less than 1/2 of those to enamel. Treatment of the dentin surface with both a surface treatment agent and primer significantly increased adhesive strength.
