Abstract:
A method for depolarizing dentin and obliterating dentinal tubule orifices of a subject with hypersensitive dentin, which comprises the steps of:providing a first liquid solution or gel comprising potassium phosphate as a first solute and at least a second solute comprising one other potassium salt selected from the group consisting of potassium carbonate, potassium fluoride and potassium oxalate; providing a second liquid solution or gel comprising a calcium salt as a first solute and at least a second solute selected from the group consisting of a salt of strontium, silver, barium and zinc; topically applying said first and second liquid solutions or gels to the dentinal tubule orifices in the dentin of a subject with hypersensitive dentin in need of dentinal depolarization and obliteration of dental tubules, and mixing topically on said dentinal tubule orifices on said hypersensitive dentin to form a dental desensitizing composition comprising the first and second solutions or gels to generate a crystal complex inside the dental tubules comprising a plurality of insoluble salts obtained by double exchange reaction of said salts, and further soluble potassium salt, wherein said insoluble salts have an obliterating effect on the dentinal tubules, said soluble potassium salt having a depolarizing effect on said dentin.
