Must in the following preparation also Mono after FOSF. 2 aq be added? If so, how much? After fluoride 250 mg menth aeth 8 DRP Water E.F. AD 500 ml

In the literature it is described that fluoride penetrates better into the tooth surface from a phosphated acid solution. In this context, I should point out the existence of sodium fluorophosphate, which is a complex salt and used by some companies in rinse solutions and fluorinated toothpaste & #039; s. And this for the reason cited above. Naturally, the solution with monosodium phosphate (Ap. Deprez) is not equivalent to the potassium phosphate but an attempt to achieve the same effect. You can try to obtain sodium fluorophosphate at the wholesale market but I fear that it will not succeed.
