Abstract

Abstract A granulated treatment-and-prophylactic dental preparation possessing anti-caries effect which comprises an abrasive substance, tartaric acid, sodium bicarbonate, a foaming agent, a flavoring agent, a binder and an anticarious substance comprising a product obtained by treatment of bone tissue with a diluted mineral acid till a complete dissolution of mineral components and water-soluble proteins contained in the bone tissue, separation of the resulting solution, dilution it with water added with a stabilizing agent citric acid or salts thereof, followed by neutralization of the solution and drying, and containing the following components, percent by weight: Calcium--2 to 6. Sodium--19 to 23. Potassium--0.04 to 0.18. Mineral acid anion--6 to 10.6. Orthophosphoric acid anion--1.5 to 5.0. Water-soluble proteins--1.0 to 5.0. Magnesium--0.05 to 0.2. Mixture of trace elements including fluorine, manganese, tin, zinc, iron--0.01 to 0.02. Complex citrates compounds as calculated for citric acid anion--the balance; and having the following proportions of the starting components, percent by weight: Tartaric acid--11 to 15. Foaming agent--1.8 to 2.27. Sodium bicarbonate--42 to 46. Binder--0.11 to 0.13. Flavoring agent--0.8 to 1.2. Substance possessing anti-caries effect--1 to 6. Abrasive substance--the balance.
