A dental adhesive composition comprising a photocurable ionomer, radiopaque metal oxide nanoparticles, a phosphorus-containing acidic monomer, another polymerizable resin component, and a polar solvent is described. In a preferred embodiment, the adhesive composition comprises a photocurable ionomer in an amount of up to 15% by weight and 5-30% by weight of radiopaque metal oxide nanoparticles (such as zirconia) comprising a basic surface. Nanoparticles comprising an organosilane surface treatment, phosphorus-containing acidic monomers in an amount of up to 10% by weight, 10% to 50% by weight of water and at least one alcohol, ketone, or mixtures thereof Including a solvent. |
