How much fluoride is in sodium fluoride?
Fluoride Varnish Varnishes are available as sodium fluoride (2.26\% [22,600 ppm] fluoride) or difluorsilane (0.1\% [1,000 ppm] fluoride) preparations.
How do you calculate ppm of fluoride?
2.5. Calculation formula
- (a) \% F = Molarity of F ( mol / L ) × Volume of sample ( L ) × 19 g / mol of F × 100 Mass / Weight of toothpaste ( g )
- (b) ppm F = \% F × 10,000.
How do you calculate fluoride ingestion?
a) To calculate the amount of F ion ingested from stannous fluoride, use the following equation: (Concentration in \%)(Amount ingested in oz)(Constant = 69)/Patient weight in kg = fluoride ion mg/kg ingested.

What contains sodium fluoride?
Sodium fluoride (NaF) is an inorganic compound with the formula NaF. It is used in trace amounts in the fluoridation of drinking water, in toothpaste, in metallurgy, and as a flux, and is also used in pesticides and rat poison. It is a colorless or white solid that is readily soluble in water.
How many mg of fluoride is in toothpaste?
Most toothpaste sold in the United States contains fluoride in the form of sodium fluoride or monofluorophosphate, most commonly at a level of 1,000 to 1,100 mg/L (about 1.3 mg in a quarter teaspoon, a typical amount of toothpaste used for one brushing) [3].
What is the RDA for fluoride?
According to the EPA, typical daily fluoride intakes in the United States from foods and beverages (including fluoridated drinking water) are 1.2 to 1.6 mg for infants and toddlers younger than 4 years, 2.0 to 2.2 mg for children aged 4–11 years, 2.4 mg for those aged 11–14 years, and 2.9 mg for adults [10].
What atoms are in sodium fluoride?
Formula and structure: The chemical formula of sodium fluoride is NaF and its molar mass is 41.99 g/mol. It is a simple ionic compound, made of the sodium (Na+) cation and fluoride (F-) anion.
