Dental adhesive composition, dental adhesive material, and dental adhesive material package

Abstract

[Object] To provide a dental adhesive composition that is highly adhesive to both porcelain and a tooth substance, an acid monomer, water, and a silane coupling agent coexisting in the dental adhesive composition, the dental adhesive composition being usable as a one-liquid type adhesive and exhibiting high preservation stability as a one-liquid type adhesive even after long-term preservation, regardless of the type of acid monomer used. [Solving Means] There is provided a dental adhesive composition characterized by including a mixture that includes a silane coupling agent (A) that does not have a silyl ether structure and includes an organic silane compound (a1) in which four monovalent groups are bonded to one silicon atom, the four monovalent groups including (i) a monovalent group having a radical polymerizable group and (ii) a monovalent group that has an alkylene chain having 3 to 40 carbon atoms and an unsaturated bond in a carbon atom at a β-position from the silicon atom; a fluoride salt (B); a polymerizable monomer (C) that contains an acidic group-containing polymerizable monomer (c1); water (D); and an organic solvent (E).
