A laboratory study was conducted to determine the shear bond strength to dentin of etched and silane‐treated Dicor castable ceramic glass using a resin cement and newer generation adhesive systems. scanning electron microscopy (SEW examinations were also completed to evaluate the failure sites. The mean shear bond strength of the control (resin cement only, no adhesive system) was 2.1 ± 1.2 MPa. The shear bond strength values determjned for the adhesive systems and resin cement are as follows: Prisma Universal Bond 2, 18.7 ± 2.9; XR Primer/XR Bond, 16.9 ± 6.4: Scotchbond 2, 15.8 ± 6.2; Tenure Solution. 15.4 ± 4.5; and Gluma, 14.8 ± 5.5 MPa. SEM examinations of the debonded specimens attached with prisms Universal Bond 2 and Tenure Solution showed a complex failure pattern with cohesive failure in the glass ceramic material and adhesive failure between the resin cement and the etched and silane‐treated glass surface. The debonding pattern of specimens attached with XR Primer/XR Bond. Scotchbond 2 and Gluma were primarily adhesive between the dentin and resin materials. The results of thfs study support the use of an adhesive system in conjunction with a resin cement for placement of Dim castable ceramic restorations.
