PROBLEM TO BE SOLVED: To provide a 1 paste self-adhesive composition for dentistry having self-adhesive properties which can firmly adhere to bio hard tissues (enamel and dentin of a tooth) etc., and the excellent color tone compatibility which can be used for aesthetic repair.SOLUTION: The invention provides a curable dental composition comprising inorganic particles (A) with a mean particle diameter in the range of 0.1-50 μm, inorganic particles (B) with a mean particle diameter in the range of 0.1-50 μm, a polymerizing monomer (C), and a polymerization catalyst (D). When the refractive index na of the inorganic particle (A) and the refractive index nb of the inorganic particle (B) have the relation: na>nb, the refractive index ne of a resin hardened substance (E) obtained by hardening the polymerizing composition having the polymerizing monomer (C) and the polymerization catalyst (D) satisfies the relation of the following formula (1): 0≤|na-ne|<0.01≤ne-nb≤0.05. |
