[Problems] A dental adhesive composition containing an acid group-containing polymerizable monomer, that can be used as a dental adhesive material or a primer. The dental adhesive composition has excellent durability of adhesion exhibiting further improved adhering strength and durability of adhesion enabling teeth to be more strongly adhered to a composite resin or a prosthetic over extended periods of time. [Means for Solution] The dental adhesive composition contains a polymerizable monomer and ions of an element of the Group IV as basic components, at least 10 mass % of the polymerizable monomer being a polymerizable monomer having a hydrogenphosphate diester group, such as bis(2-methacryloyloxyethyl)hydrogenphosphate or 2-methacryloyloxyethylphenyl hydrogenphosphate, and the content of ions of the element of the Group IV such as titanium ions or zirconium ions in the composition being 0.1 to 1.0 in terms of mole ratio to the hydrogenphosphate diester groups of the polymerizable monomer that has the hydrogenphosphate diester group.

Dental adhesive composition

Provided is a filling/restoring material, including a photopolymerization initiator of a quaternary system formed by combining an &#x3b1;-diketone compound, an aliphatic amine compound, an aromatic amine compound, and a photoacid generator, in which even when the filling/restoring material is filled and cured on a cured layer of a dental adhesive material including a radical-polymerizable monomer having an acidic group, the filling/restoring material undergoes sufficient curing up to a contact interface between the filling/restoring material and the cured layer, thereby providing high adhesive strength stably. Also provided is a dental filling/restoration kit, including: a filling/restoring material including: a polymerizable monomer having no acidic group; a basic inorganic material; and a photopolymerization initiator formed by at least combining: an &#x3b1;-diketone compound; an aliphatic amine compound; an aromatic amine compound; and a photoacid generator; and an adhesive material, which is used for adhesion between a tooth and the filling/restoring material by curing the adhesive material before filling the filling/restoring material, the adhesive material including: a polymerizable monomer including a polymerizable monomer having an acidic group; and a polymerization initiator.
