摘要:
[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.
