ABSTRACT
PURPOSE:
To evaluate the shear bond strength of two dual-cured resin luting cements (Linkmax HV and Panavia Fluoro Cement) to machinable glass-ceramics (Decsy Machinable Ceramic) and the effect of three silane coupling agents (Clearfil Porcelain Activator, Ceramic Primer, and Porcelain Liner M) on the bond strength.METHODS:
Disk-shaped specimens fabricated from machinable glass-ceramic blocks using a low-speed cutting saw were either treated or not treated with one of three silane coupling agents and then bonded together with one of two dual-cured resin luting cements. Specimens were stored in water at 37degrees C for 24 hours and/or thermal cycled 50,000 times before shear bond strength testing.RESULTS:
Regardless of the resin luting cement and thermal cycling, specimens treated with the Clearfil Porcelain Activator showed the highest shear bond strength among all the treatments. Surface treatment of the Clearfil Porcelain Activator showed significantly greater shear bond strength after 50,000 thermocycles compared with other treatments. However, significant differences in bond strength were observed between 0 and 50,000 thermocycles for all treatments.
