Character of the hard tooth tissue-polymer bond. II. Study of the interaction of human tooth enamel and dentin with N-phenylglycine-glycidyl methacrylate adduct.

The interaction of powdered human tooth enamel and dentin with NPG-GMA was studied in alcoholic and alcoholic-aqueous solutions. The reaction produces ionized carboxylic groups capable of forming ionic bonds between the calcium ions in the tooth enamel or dentin and NPG-GMA.
