Abstract: A dentifrice, such as toothpaste, containing chitosan or pharmaceutically acceptable acid addition salt thereof with fluoride ions, for use against erosive tooth demineralization, and kits containing chitosan or pharmaceutically acceptable acid addition salt thereof with fluoride ions, wherein one of the two active agents is comprised in a dentifrice, are described. The dentifrice in the form of toothpaste may furthermore comprise dissolved tin, in particular stannous ions. Toothpastes containing chitosan or pharmaceutically acceptable acid addition salt thereof with fluoride ions are tested in the treatment or prevention of erosive tooth demineralisation caused by citric acid.

Abstract: A mouthrinse containing chitosan or pharmaceutically acceptable acid addition salt thereof with fluoride ions, for use against erosive tooth demineralization, and kits containing chitosan or pharmaceutically acceptable acid addition salt thereof with fluoride ions, wherein one of the two active agents is comprised in a mouthrinse, are described. The mouthrinse may furthermore comprise dissolved tin, in particular stannous ions. Mouthrinses containing chitosan or pharmaceutically acceptable acid addition salt thereof with fluoride ions are tested in the treatment or prevention of erosive tooth demineralization caused by citric acid.

Abstract: An oral care composition comprising a liquid phase containing 30% to 90%, preferably 30% to 80% by weight, based on the liquid phase, of water; dissolved tin; 200 to 2000 ppm fluoride ions, based on the oral composition; and 5 to 60% by weight, based on the oral care composition, of a C(3-5) sugar alcohol; characterised in that the content of dissolved tin [Sn] in the liquid phase is at least 750 ppm, preferably at least 1000 ppm, based on the composition; that 60 mol % or more, preferably 75 mol % or more of the content of dissolved tin [Sn] is in the formal oxidation state +II; and that the composition comprises an organic acid and ammonium cations of the Formula (I): R—NH+Ra—[(CH2)u—NH+Rb]v—Rc (I), wherein R is a saturated or unsaturated straight-chain hydrocarbon residue of 10 to 20 carbon atoms, v is an integer from 0 to 1, u is an integer from 2 to 3 and Ra, Rb and Rc are independently selected from hydrogen and —CH2CH2OH. The composition is preferably a mouthrinse.
