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

The antimicrobial activity of several visible light cured glass ionomer and liner materials against three bacteria commonly found in the oral cavity is discussed. Vitrabond light cure glass ionomer produced zones of inhibition against all the bacteria tested in this study. It appeared to resemble a true glass ionomer cement in regard to its antimicrobial properties whereas the other materials used in this study appeared to possess no antimicrobial activity.
