Abstract:
The aim of this study was to investigate the effect of 2-hydroxyethyl methacrylate (HEMA) in an Al2Ox3/glycine solution used as primer for dentin bonding in combination with an experimental BISGMA-HEMA-based adhesive resin. With various amounts of HEMA in the Al2Ox3/glycine solution, a shear bond test showed a maximum strength at 50 wt% of HEMA. In this case, scanning electron microscopy examination showed a HEMA-infiltrated surface layer of the dentin along the interface between dentin and the adhesive resin. It is suggested that HEMA in Al2Ox3/glycine solutions may facilitate penetration of HEMA into etched or primed dentin.
