FIELD: medicine.

SUBSTANCE: invention refers to dentistry and concerns a set of restorative materials intended for restoration of a tooth having a cavity. Kit comprises a first polymerisation curable composition (A) for forming a surface layer intended to be exposed on a surface after restoration, and a second polymerization curable composition (B) for forming a base layer serving as a base for the surface layer. First polymerisable composition (A) comprises a first polymerisable monomer component which is at least one type of (meth) acrylic polymerisable monomer; inorganic spherical particles, which are composite oxide particles based on silicon dioxide and oxide of an element from the group of titanium, and a component which is a first polymerisation initiator. Said spherical particles and monomer component have refraction indices in certain ranges. First polymerisation-curable composition (A) is formed into a hardened body which exhibits a structural colour by dispersion in a matrix of inorganic spherical particles in a specific dispersion state. Second polymerisable composition contains a second polymerisable monomer component, a dye component and a second polymerisation initiator component, wherein the dye component is mixed such that the value (V) of the colorimetric value according to the colour system of the Mansell colour system for the coloured light, measured with a colour difference meter on a black background, is 5 or more in comparison with the sample containing the cured product (B') from a second polymerization curable composition (B) and having thickness of 1 mm.

EFFECT: using the proposed set of filling restorative materials is able to provide high colour tone compatibility even when used for restoration of class III and IV cavities.
