Title: DENTAL RESTORATIVE COMPOSITION
Abstract:
Provided is a dental restorative composition that has favorable handleability in a paste condition before being cured and will have light diffusion properties and transparency when cured. This dental restorative composition includes a polymerizable monomer, a polymerization initiator, an inorganic filler (C) having an average particle size of 0.1 to 1 μm, an organic-inorganic composite filler (D) having an average particle size of 1 μm or more and less than 10 μm, and an organic-inorganic composite filler (E) having an average particle size of 10 to 50μm. The absolute value of the difference between the refractive index (Cd) of the inorganic filler (C) and the refractive index (Ad) of a polymer of the polymerizable monomer is 0.01 or less, the absolute value of the difference between either the refractive index (Dd) of the organic-inorganic composite filler (D) or the refractive index (Ed) of the organic-inorganic composite filler (E) and the refractive index (Ad) is 0.01 or less, and the absolute value of the difference between the other refractive index and the refractive index (Ad) is 0.03 or more.
