This study compared the shear bond strength of resin composite bonded to porcelain with six commercial porcelain repair adhesive systems. The porcelain repair systems tested were: All-Bond 2, Clearfil Porcelain Bond, Ceram-Etch, C&B Metabond with Etch-Free Primer, Scotchprime, and Ultradent Porcelain Etch. Resin composite cylinders were bonded to primed porcelain surfaces and the specimens were thermocycled and stored in distilled water at 37 degrees C for 36 days. After storage, a testing machine was used to deliver a shear force parallel to the porcelain/composite interface. Mean load to failure was calculated for each group and the fracture location was noted. Results demonstrated cohesive porcelain failures and high bond strengths for All-Bond 2, Clearfil, Metabond, Scotchprime, and Ultradent. Statistical analysis revealed significantly lower bond strengths for the group that failed at the porcelain/composite interface.
