Abstract

According to one aspect of the present invention, a dental curable composition includes: polymerizable monomers; inorganic particles (A1) and/or inorganic particles (A2) (excluding the inorganic particles (A2); and inorganic particles (B). The inorganic particles (A1) are surface-treated with a compound expressed by a general formula (1) and have a volume-median particle size of greater than or equal to 0.1 μm and less than or equal to 0.9 μm. The inorganic particles (A2) are surface-treated with a compound expressed by a general formula (2) and have a volume-median particle size of greater than or equal to 0.1 μm and less than or equal to 0.9 μm. The inorganic particles (B) are particles where a group expressed by a general formula (A) is present at surfaces, are particles where a group expressed by a general formula (B) is present at surfaces, and/or are particles surface-treated with a compound expressed by a general formula (3) and have an average primary particle size of greater than or equal to 5 nm and less than or equal to 50 nm. A ratio of a mass of the inorganic particles (B) to a total mass of the inorganic particles (A1), the inorganic particles (A2), and the inorganic particles (B) is greater than or equal to 0.001 and less than or equal to 0.015.
