Abstract: A gel for dental caries prevention is disclosed, comprising a gelling agent, a humectant, a surface active material, a flavoring material, 1.7-11% by weight of an anti-caries agent which is a mixture of sodium monofluorophosphate with a substance obtained from treating the bone tissue with a diluted mineral acid to completely remove the mineral components and water-soluble proteins contained in bone tissue, isolation of the thus obtained solution, diluting it with water and stabilizing additives of citric acid or salts thereof, with subsequent neutralization of the solution and drying, and including the following parts and proportions by weight %:______________________________________ calcium 2-6 sodium 19-23 potassium 0.04-0.18 anion of mineral acid 6-10.6 anion of orthophosphoric 1.5-5.0 acid water-soluble proteins 1.0-5.0 magnesium 0.05-0.2 complex of microelements 0.01-0.02 including fluorine, manganese, tin, zinc, iron complex citrate compounds the rest.

Abstract: A drug for treatment of dental caries, comprising an active principle, namely, a mixture of sodium monofluorophosphate and an anticarious preparation obtained by treating osseous tissue with a diluted mineral acid till a complete dissolution of mineral components and water-soluble proteins contained in the osseous tissue, separating the solution, diluting it with water, adding a stabilizer, i.e., citric acid or its salt, to the solution, and neutralizing and evaporating the solution, which anticarious preparation has the following percentage-by-weight composition:______________________________________ calcium 2-6 sodium 19-23 potassium 0.04-0.18 mineral acid anions 6-10.6 orthophosphoric acid anions 1.5-5.0 water-soluble proteins 1.0-5.0 magnesium 0.05-0.2 trace elements, including fluo- rine, manganese, tin, zinc, and iron 0.01-0.
