Abstract

A method for infiltration and/or sealing of hard tooth tissue and for detection of caries in the infiltrated region or under the seal by means of fluorescence, is described. The method includes applying a composition comprising a filler system consisting of or comprising inorganic filler particles surface-modified by means of organic structural elements, wherein the organic structural elements can be reacted with an organic binder system to form covalent bonds, wherein the filler particles of the composition have an average particle size in the range between 1 nm and 150 nm, and an organic binder system comprising one or more polymerizable monomers, wherein the filler system is dispersed in the organic binder system (b). The infiltrated or sealed surface of the hard tooth tissue is then irradiated with excitation radiation which causes emission of fluorescence radiation. The fluorescence radiation data is recorded and used to detect curies.
