A self-etching primer which comprises an aqueous solution of a methacrylic acid derivative such as N-methacryloylglycine, N-methacryloyl-3-aminopropionic acid, N-methyacryloyl-4-aminobutyric acid, N-methacryloyl-5-aminovaleric acid, N-methyacryloyl-6-aminocaproic acid, N-methacryloyl-2-aminomethylphosphonic acid, N-methacryloyl-3-aminoethylphosphonic acid, or N-methacryloyl-4-aminopropylphosphonic acid. When the dentin or enamel of a tooth is treated with the primer before a composite resin, adhesive resin cement, or the like is bonded thereto, then adhesion strength is highly enhanced. |
