摘要:
A dental composition of the present invention includes: a polymerizable monomer (A); 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; and inorganic particles (C) having an average particle of 0.1 to 1.0 µm. The oxide contains a zirconium atom, a silicon atom, and an oxygen atom. It is preferable that the dental composition contain 50 to 400 parts by weight of the filler (B) and 100 to 400 parts by weight of the inorganic particles (C) per 100 parts by weight of the polymerizable monomer (A).
