1452125 Remineralizing teeth PROCTER & GAMBLE CO 12 Oot 1973 [13 Oct 1972] 47800/73 Heading A5B A pack for remineralizing teeth comprises (A) a cation in water-soluble form which cation is capable of forming an insoluble preciptate and (B) an anion in water-soluble form which is capable of forming with the cation an insoluble precipitate adapted to remineralize subsurface dental enamel, one of both of components (A) and (B) containing a flavouring agent, the components being compatible with the oral environment and being such as to have a pH from 3 to 10 in solution. In use, the two components are applied sequentially to the tooth, the remineralizing precipitate being thereby formed in situ. Cations specified are calcium, indium, barium, lanthanium, manganese, lead, tin, zinc, zirconium, iron, titanium, vanadium, cadmium, magnesium, aluminium, strontium, cesium, samarium, praseodymium, neodymium, nickel, lithium (with phosphate), molybdenum, vanadium, tungsten. Anions specified are fluoride, phosphate, fluorophosphate, silicofluoride, molybdate, sulphate, tungstate, 8-hydroxyquinolate, tartrate, sorbate, carbonate, iodate, stearate, hydroxide, palmitate, myristate, laurate, oxalate, decyl sulphonate, lauryl sulphonate, myristyl sulphonate, cetyl sulphonate, octadecyl sulphonate, silicate, hexadecyl sulphonate, aluminate. Physical forms of the two components specified are: mouthwashes, toothpastes, beverages, candy drops, foods, toothpowders, chewing gum, toothpaste in which one component is encapsulated and a multilayer lozenge. |
