Abstract
A dental composition of the present invention includes: a polymerizable monomer component (A); and an amorphous filler (B) having an average particle size of 1 to 20 μm and including silica-based fine particles and coatings of an oxide that cover the surfaces of the silica-based fine particles. The oxide contains a zirconium atom, a silicon atom, and an oxygen atom. The dental composition contains 20 to 500 parts by weight of the filler (B) per 100 parts by weight of the polymerizable monomer component (A). The dental composition has a viscosity of 10 to 800 Pa·s. It is preferable that the filler (B) contain spherical particles, and that the percentage of the spherical particles in the filler (B) be at least 60%.
