Abstract
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.
Description
Background of the invention [0001] This invention relates generally to dental compounds and, more particularly, to dental compositions for the treatment of tooth hypersensitivity. [0002] In particular, this composition is suitable for desensitizing exposed dentin, especially for: [0003] A desensitization treatment for deep cavities, [0004] - hypersensitive treatment when replacing tooth layers, [0005] 1. Desensitization of residues before placing dentures. [0006] The composition can be used in the form of a solution or a gel. [0007] Description of prior art [0008] Dentin hypersensitivity is a common problem faced by dentists among their patients, and it is often exacerbated when hot or cold foods, sweet or sour foods are consumed, and when teeth are brushed. [0009] Normal dentin is covered by enamel (crown) or by cementum (root) and is impermeable. [0010] In hypersensitive areas of the tooth, it is often found that the enamel is eroded or...
