Effect of 2-hydroxyethyl methacrylate in an Al2Ox3/glycine solution used as primer for dentin bonding.
    Acta odontologica Scandinavica, 1991, Volume: 49, Issue:5

    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.

Amine-induced polymerization of aqueous HEMA/aldehyde during action as a dentin bonding agent.
    Journal of dental research, 1990, Volume: 69, Issue:6

    Aqueous mixtures of HEMA with glutaraldehyde or propionaldehyde polymerize by addition of catalytic amounts of amines or amino acids. The maximal reaction velocity of the transformation of HEMA/glutaraldehyde with glycine was obtained at pH 0.8. Kinetic data suggested a second-order reaction between glutaraldehyde and glycine, and solubility data suggested formation of a cross-linked polymer. A relatively high bond strength between dentin and resin composite was obtained by pre-treatment of dentin with Gluma (35% HEMA, 5% glutaraldehyde in water) adjusted to pH 1.0 with hydrochloric acid. It is proposed that on application of Gluma, amino-group-containing substances in dentin react with glutaraldehyde and start the formation of a HEMA polymer. This product may be cross-linked by an alpha,beta-unsaturated glutaraldehyde aldol condensation product and may bond to dentin by aldehyde fixation to dentin proteins. Resin composite will bond to this product by copolymerization.
