The bond strength of this sandwich was also compared with that of the same cements used in bulk. Vitrebond showed a significantly higher bond strength in bulk than did the other two cements. Of the sandwiches, the XR-Ionomer and XR-Bond combination showed a bond strength significantly higher than that of the Vitrebond and Scotchbond or Ketac-Bond and Scotchbond combination. The f racture of the bond was mainly adhesive for Vitrebond, cohesive for XR-Ionomer when used in bulk and adhesive-cohesive when used in a sandwich, and cohesive for Ketac-Bond.
