A dental restorative material including a photocurable composition that contains a polymerizable monomer component (A), an inorganic filler component (B) having an average particle size of not smaller than 0.07 µ m, and a photo polymerization initiator (C),
the inorganic filler component (B) being contained in an amount of 100 to 1500 parts by mass per 100 parts by mass of the polymerizable monomer component (A), and
the polymerizable monomer component (A) and the inorganic filler component (B) being so selected as to satisfy a condition (X1) represented by the following formulas (1a) and (1b): nF - 0.005 < nM < nF + 0.005 nF + 0.020 < nP < nF + 0.040
wherein,
nM is a refractive index of the polymerizable monomer component (A) at 25°C,
nP is a refractive index at 25°C of a polymer obtained by polymerizing the polymerizable monomer component (A), and
nF is a refractive index of the inorganic filler component (B) at 25°C. |
