ABSTRACT:
Bond strength of a composite resin, an adhesive resin cement or the like to dentin or enamel of tooth is remarkably improved by treating the dentin or the enamel with a self-etching primer agent comprising an aqueous solution of a methacrylic acid derivative such as N-methacryloylglycin, N-methacryloyl-3-aminopropionic acid, N-methacryloyl-4-aminobutyric acid, N-methacryloyl-5-aminovaleric acid, N-methacryloyl-6-aminocaproic acid, N-methacryloyl-2-aminomethylphosphonic acid, N-methacryloyl-3-aminoethyl-phosphonic acid and N-methacryloyl-4-aminopropylphosphonic acid.
