In a scanning electron microscope study evaluating the effects of a 10% carbamide peroxide gel on stained enamel and dentin, no surface morphologic changes were observed after 72 hours of contact with the bleaching gel

This study was to determine the bond strength of composite to glass ionomer using the following adhesive resin cements: Imperva Dual, CB Metabond, All-Bond, Geristore, and Panavia. All materials were mixed following the manufacturer's specifications. Bonded samples were thermocycled for 2000 x between 5 degrees C and 55 degrees C. Shear bond strengths were determined using an Instron Testing Machine. No statistical differences were noted between materials at the p < .05 level of significance. In addition, scanning electron micrographs were taken of the primed glass ionomer surfaces. These micrographs revealed varying amounts of matrix dissolution along with roughened surface topographies
