Abstract
In this study, we performed two experiments to clarify the influence of adhesion reducing factors. In Experiment 1, we investigated the basic bond strength of two kinds of cements, glass ionomer and polycarboxylate cements. In Experiment 2, we investigated bond strength on metal surface under three conditions in which the surface was contaminated by two kinds of fitness test materials (white silicone and green rouge) and saliva. As the metal substrates 12% Au-Ag-Pd alloy was used in order for that the results could reflect its clinical use. We evaluated the bond strength by a compression shear test. In Experiment 1, the bond strength of polycarboxylate cement (35.4kgf/cm2) was significantly (p<0.01) higher than that of glass ionomer cement (19.6kgf/cm2) . In Experiment 2, the bond strength decreased under the three surface conditions. Thus the results indicated that the three contaminants were factors reducing adhesion. Among the three conditions, saliva caused the greatest (p<0.01) reduction in bond strength (16.5 kgf/cm2) .
