Abstract

See full text

A single-paste, self-adhesive dental curable composition that has strong self-adhesion to biological hard tissues (such as enamel and dentin of teeth) and good color tone adaptability suitable for use for aesthetic restoration is provided. A dental curable composition contains: an inorganic particle (A) with an average grain size in the range of 0.1 to 50 μm; an inorganic particle (B) with an average grain size in the range of 0.1 to 50 μm; a polymerizable monomer (C); and a polymerization catalyst (D). The refractive index na of the inorganic particle (A) and the refractive index nb of the inorganic particle (B) meet the relationship of na>nb. A cured resin material (E), which is obtained by curing a polymerizable composition containing the polymerizable monomer (C) and the polymerization catalyst (D), has a refractive index ne that meets the relationship (1):
