Abstract

The present invention provides a dental color tone adjustment material kit that has improved properties in terms of surface drying and of discoloration after curing and that enables adjustment to a desired color tone. The present invention relates to a dental color tone adjustment material kit including: a primer composition (A) including an acid group-containing polymerizable monomer (a) and a volatile organic solvent (b); and a dental color tone adjustment material B including a polymerizable monomer (d), a polymerization initiator (e), particle aggregates (f) that are chain aggregates of ultrafine filler particles having an average primary particle diameter of 1 to 50 nm, titanium dioxide (g), and a pigment (h). The monomer (a) accounts for 0.05 to 45 weight % of the primer composition (A), and the organic solvent (b) accounts for 55 to 99.95 weight % of the primer composition (A). The monomer (d) includes a polyfunctional acrylate monomer (d1) and a volatile monofunctional (meth)acrylate monomer (d2), and the monomers (d1) and (d2) account for 88 weight % or more of the monomer (d). The content of the particle aggregates (f) is 5 to 20 parts by weight, and the content of the titanium dioxide (g) is 0.05 to 2 parts by weight, per 100 parts by weight of the total of the monomer (d) and the particle aggregates (f).
