Patent ID: 8436078

Claim:
A dental composition comprising: a polymerizable monomer (A); an amorphous powder (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 containing a zirconium atom, a silicon atom, and an oxygen atom, and inorganic particles (C) having an average particle size of from 0.1 to 1.0 μm wherein a difference in refractive index between a cured product of the polymerizable monomer (A) and the amorphous powder (B) is 0.005 to 0.03, and wherein the dental composition comprises 50 to 400 parts by weight of the inorganic particles (C) per 100 parts by weight of the polymerizable monomer (A).
