A patient who drinks large quantities of sugary beverages presents with white spot lesions. What treatment is indicated?
Show answer and explanation
Correct answer: B. Topical sodium fluoride
- A. Incorrect. Restoring a non-cavitated reversible lesion needlessly destroys sound tooth structure.
- B. Per the recall source. White spot lesions are non-cavitated demineralisation and are reversible. Topical fluoride drives remineralisation by forming the more acid-resistant fluorapatite.
- C. Partially correct but less complete. MI Paste (CPP-ACP) supplies calcium and phosphate but the fluoride-containing version (MI Paste Plus) is preferred where fluoride is not contraindicated. Plain MI Paste is intended for children under six and pregnant women.
- D. Incorrect. Chlorhexidine reduces the bacterial load but does not remineralise enamel.
Note: 📌 The key principle: white spot lesions are NON-CAVITATED and reversible — remineralise rather than restore. Fluoride is first-line; CPP-ACP (MI Paste) is an adjunct.
