A one-pact type adhesive composition for dental use which is obtained by compounding as essential ingredients a hydrophobic polymerizable monomer (a) having an acid group, a water-soluble polymerizable monomer (b), water (c), a photopolymerization initiator (d), an aromatic tertiary amine (e) having an electron-attracting group, a crosslinking polymerizable monomer (f), and a basic compound (g) which reacts with part of the hydrophobic polymerizable monomer (a) having an acid group to generate a water-soluble salt. The composition has excellent bonding strength in the bonding of a tooth, especially enamel or dentine, to a dental repairing material, especially a resinous material, and has excellent storage stability. Because the composition is of the one-pact type, no mixing operation is necessary in preparation for bonding. Furthermore, the composition has excellent bonding strength even without conducting pretreatments (etching and priming). The composition is hence suitable for use as a one-step type dental adhesive composition for conducting a tooth repair treatment through one bonding operation. |
