The aim of this study was to investigate the effect of different resin cement film thicknesses on the shear bond strength of resin core materials to lithium disilicate ceramics. Forty IPS Empress 2 ceramic disks were bonded to the core materials (Bis-core and Smile) with resin cement film thicknesses of 50 or 100 mu m. Shear bond strength was measured using a universal testing machine. Data were analyzed using two-way analysis of variance and independent t tests. The core material used and resin cement film thickness had a significant effect on shear bond strength values (P<.001). Greater resin cement film thickness resulted in decreased bond strength of the core materials to lithium disilicate ceramics. Int J Prosthodont 2010; 23: 469-471.
