Bonding Composite to Glass lonomer with Adhesive Resin Cements

Abstract

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.
