For an adult patient with high caries risk, which toothpaste ingredient provides the greatest benefit?
Show answer and explanation
Correct answer: B. Stannous fluoride (SnF₂)
- A. ❌ Sodium fluoride provides remineralization/fluoride benefits but lacks the antimicrobial properties of stannous fluoride.
- B. ✅ Correct. STANNOUS FLUORIDE provides dual benefits: (1) FLUORIDE ions for remineralization and (2) ANTIMICROBIAL activity against S. mutans and other cariogenic bacteria, plus plaque inhibition and sensitivity reduction. Superior to NaF alone for high-caries-risk patients.
- C. ❌ Potassium nitrate is a desensitizing agent — not primarily anti-caries.
- D. ❌ Triclosan (largely discontinued) had antimicrobial properties but is not the preferred choice for high caries risk management.
