title: [Fluoride release from toothpastes in the newly produced and stored states].
abstract: The free ionic concentration of fluoride of 16 toothpastes for adults, of 5 pastes for children, and of one fluoride gel were analysed straight after production and after 4 months of storage. The fresh products containing fluoride as inorganic salt of hydrofluoric acid or as organic fluoride salt contained more than 65% of the manufacturers declaration of ionic fluoride. In the pastes containing sodiummonofluorphosphate the assessed concentration of free fluoride ions was less than 20% of the declaration. After 4 months of storage more than 75% of the ionic fluoride found in the new products could still be detected. The pastes containing sodiummonofluorphosphate, however, showed an increase of the ionic concentration of fluoride.
