The effectiveness of Laminabond Porcelain Primer on the porcelain adhesion was investigated in this study. The lamina Bond Porcelain Primer was newly commercial availablesilane coupling agent which is one bottle type. The porcelain surface was polished with # 1, 000 paper and treated with Lamina Bond Porcelain Primer for 30 seconds. As composite resin, Lamina Bond Composite Resin or Esthelay Cementwere used. The shear bond strengths between composite resin and porcelain, and thosebetween enamel and porcelain mediated by the composite resin were measured after one dayimmersion in 37°C water or thermocycles between 4°C and 60°C. While without Porcelain Primer treatment, the bond strengths between composite resin andporcelain were as low as about 50 kgf/cm2, with Primer treatment the bond strengths increased toabout 150 kgf/cm2. After thermal cycling tests, the bond strengths of Lamina Bond Composite Resin to the primed porcelain remarkably decreased, but those of Esthelay Cement did not. There were no decrease of the bond strengths between enamel and Primer treated porcelainmediated by the composite resin after thermal cycling tests.
