Abstract
The present invention provides a dental curable composition exhibiting both excellent light diffusion and excellent transparency, and having high mechanical strength and surface smoothness and gloss after polishing as a cured product as well as good handling properties as a paste. The present invention is a dental curable composition including: a polymerizable monomer (A) having a refractive index of 1.52 to 1.58 after polymerization; inorganic particles (B) having a refractive index of 1.43 to 1.50; and inorganic particles (C) having a refractive index of 1.52 to 1.58. The inorganic particles (B) are aggregates of inorganic fine particles having an average primary particle size of 2 to 50 nm, and the content of the inorganic particles (B) is 0.1 to 10% by weight.
