Abstract: A dental adhesive set is disclosed, comprising (I) a tooth surface conditioning agent and (II) a bonding material, wherein the tooth surface conditioning agent (I) is an acid aqueous solution, and the bonding material (II) comprises a mixture of: (a) a fluoroalumino silicate glass powder, (b) one or two or more unsaturated organic compounds selected from polymerizable unsaturated organic compounds having at least one CH2═CR1—COO—, wherein R1 is H or CH3, and not having an acid group; (c) an acid; (d) water; and (e) a photopolymerization catalyst. According to the dental adhesive set of the present invention, the dental restoration and the dentin can be firmly and surely adhered to each other in a clinically simple operation, and by imparting properties for continuously releasing a fluoride ion not only the dentinal restoration but also the reinforcement of tooth structure and the inhibition of secondary caries can be expected.

Abstract: A dental adhesive kit is disclosed, comprising a combination of: (i) a self-etching primer comprising (A) from 1.0 to 50% by weight of a methacrylate or acrylate having an acidic group and having at least one unsaturated double bond, (B) from 1.0 to 98% by weight of a water-soluble organic solvent, and (C) from 1.0 to 90% by weight of water; and (ii) a bonding agent comprising (D) from 10 to 90% by weight of a methacrylate or acrylate having neither acidic group nor hydroxyl group and having at least one unsaturated double bond, (E) from 10 to 90% by weight of a methacrylate or acrylate not having an acidic group but having a hydroxyl group and having at least one unsaturated double bond, (F) from 0.1 to 5.0% by weight of a photopolymerization initiator, (G) from 0.1 to 5.0% by weight of a photopolymerization accelerator, and (H) from 1.0 to 60% by weight of a filler.
