A dental composition for the treatment of dentinal hypersensitivity and in particular for the desensitization of exposed dentin, the desensitizing treatment of deep cavities, the desensitizing treatment when replacing dental layers, the stumps desensitizing treatment before placing dental prosthesis. The composition can be used as a solution or as a gel. In the first case two distinct liquid solutions for use successively on the exposed dentin are provided for. In the second case two distinct gel compounds spread successively on the exposed dentin are provided for. The first solution or the first gel compound comprises preferably three soluble potassium salts, whereas the second solution or the second gel compound comprises a calcium salt and a soluble strontium salt. In a preferred composition two solutions are provided for of which the first has solutes comprising potassium phosphate, potassium carbonate and potassium fluoride, and the second solution has solutes comprising calcium chloride and strontium chloride. For the gel composition, which may be used as toothpaste, two distinct gel compounds are provided, the first having solutes comprising potassium phosphate, potassium carbonate and potassium fluoride and the second gel compound having solutes comprising calcium chloride and strontium chloride.

Cette invention a trait à une composition dentaire permettant de traiter l'hypersensibilité dentinaire et, notamment, de désensibiliser la dentine mise à nu, d'effectuer un traitement de désensibilisation de cavités profondes, un traitement de désensibilisation au moment de remplacer des couches dentaires ainsi qu'un traitement de désensibilisation des moignons avant la mise en place de prothèses dentaires. Cette composition peut se présenter sous la forme d'une solution ou d'un gel. On utilise successivement, dans le premier cas, deux solutions liquides distinctes pour traiter la dentine et, dans le second cas, on étale successivement deux composés sous forme de gel sur la dentine mise à nu. La première solution ou le premier gel renferment, de préférence, trois sels de potassium solubles alors que la seconde solution ou le second gel contiennent un sel de calcium et un sel de strontium soluble. La composition préférée se présente sous la forme de deux solutions distinctes, la première renfermant des solutés comprenant du phosphate, du carbonate et du chlorure de potassium et la seconde des solutés comprenant du chlorure de calcium et du chlorure de strontium. La composition sous forme de gel pouvant être utilisée comme pâte dentifrice se présente sous la forme de deux gels distincts, le premier renfermant des solutés comprenant du phosphate, du carbonate et du chlorure de potassium et le second des solutés comprenant du chlorure de calcium et du chlorure de strontium.
