Abstract
A dental adhesive agent includes a polymerizable monomer; first and second inorganic particles which have been subjected to a surface treatment by a chemical compound, respectively; and a third inorganic particle. The first inorganic particle has a volume median diameter greater than or equal to 0.1 μm and less than or equal to 0.5 μm, the second inorganic particle has a volume median diameter greater than or equal to 0.6 μm and less than or equal to 0.9 μm, and the third inorganic particle has a mean primary-particle diameter greater than or equal to 5 nm and less than or equal to 50 nm. The mass ratio of the third inorganic particle with respect to the gross mass of the first inorganic particle, the second inorganic particle and the third inorganic particle is greater than or equal to 0.001 and less than or equal to 0.05.
