Compositions for infiltration and/or sealing of hard tooth tissue and corresponding methods
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.

Phosphate crosslinked starch nanoparticle and dental treatments
ActiveUS20210000710A1Cosmetic preparationsOrganic active ingredientsActive agentTooth Remineralization
A phosphorous compound such as STMP is used as a cross-linking agent while making a starch nanoparticle in an emulsion process. Negative charge of the nanoparticle is reduced or reversed by adding cations and / or cationizing the starch optionally while forming the nanoparticles. Anionic active agents, such as fluoride or fluorescein, are optionally incorporated into the nanoparticle during the formation process. For example, a fluoride salt can also be used, which promotes the crosslinking reaction while also providing fluoride in the nanoparticle. The retention of both calcium and fluoride in the nanoparticle is improved when both salts are used. Alternatively, the nanoparticle may be used without added calcium and / or fluoride. The nanoparticles may be useful for tooth remineralization, the treatment of dentinal hypersensitivity, to treat caries, or as a diagnostic agent to locate carious lesions.
