Abstract
The aim of this study was to evaluate the effect of the zirconia slurry application on the bond strength between veneering porcelain and zirconia core by means of a shear bond test. Fifteen bilayered beam-shape specimens were prepared and divided into 3 groups according to zirconia slurry application. A shear bond strength test was used on each specimen. One-way ANOVA and the Tukey honestly significant difference test were performed to analyze the experimental data. The bond strength with a zirconia slurry had higher mean values than the bond strength without a zirconia slurry. Both of the interfaces showed mixed failure mode with thin layers of a veneer or a zirconia slurry that remained on the zirconia surfaces. Zirconia slurry application before veneering increased the bond strength between zirconia and veneer.
