摘要： Provided is a dental restorative composition that has good handling properties when in the form of a paste having yet to be cured and that has light diffusion ability and transparency when in the form of a cured product. The dental restorative composition includes a polymerizable monomer, a polymerization initiator, an inorganic filler (C) having an average particle diameter of 0.1 to 1 µm, an organic-inorganic composite filler (D) having an average particle diameter of 1 µm or more and less than 10 µm, and an organic-inorganic composite filler (E) having an average particle diameter of 10 to 50 µm. An absolute value of a difference between a refractive index (Cd) of the inorganic filler (C) and a refractive index (Ad) of a polymer of the polymerizable monomer is 0.01 or less, an absolute value of a difference between the refractive index (Ad) and one of a refractive index (Dd) of the organic-inorganic composite filler (D) and a refractive index (Ed) of the organic-inorganic composite filler (E) is 0.01 or less, and an absolute value of a difference between the refractive index (Ad) and the other of the refractive index (Dd) and the refractive index (Ed) is 0.03 or more.
