PROBLEM TO BE SOLVED: To provide a dental composition with suppressed sedimentation of fumed silica, excellent applicability, high adhesive strength of a cured body and excellent durability thereof.SOLUTION: In a dental composition comprising a polymerizable monomer, a fumed silica and a solvent, the average primary particle diameter of the fumed silica is 1 to 20 nm, the median diameter of the agglomerated secondary particle diameter of the fumed silica as measured by the laser diffraction scattering method is 50 to 500 nm, and the ratio of the fumed silica having an agglomerated secondary particle diameter of 50 to 500 nm is 90 vol.% or more. |
