What chemical compound is represented by the symbol NaF most commonly used in dental fluoride applications?

• A. Sodium fluoride
• B. Stannous fluoride
• C. Potassium fluoride
• D. Calcium fluoride

Answer: (A)

NaF is sodium fluoride, a fluoride salt that readily releases fluoride ions in the mouth. This makes it ideal for dental use, as the fluoride ions promote remineralization of enamel and help prevent caries. It’s highly soluble, stable, and easily incorporated into a wide range of products like toothpastes, mouth rinses, gels, and varnishes, which is why it is the most commonly used fluoride source in clinical applications. Other fluoride salts exist—stannous fluoride can cause staining and taste issues; calcium fluoride is less soluble and delivers fluoride more slowly; potassium fluoride is less commonly used for routine products—so they don’t offer the same practical combination of stability, bioavailability, and user acceptability that sodium fluoride provides.
