Correct answer: E — No less than 1000 ppm fluoride
Explanation lettering: E = shown as A · D = shown as B · B = shown as D · A = shown as E
The correct answer is A. Current UK guidance (Delivering Better Oral Health, NICE CG55, NHS) consistently recommends that children aged 0–3 years use fluoride toothpaste containing no less than 1000 ppm fluoride, applied as a smear (approximately rice-grain size) to reduce fluorosis risk while maintaining caries-preventive benefit. Option C (1350–1500 ppm) is reserved for higher-risk children or general family use from age 3+. Options B and D (450 and 500 ppm) fall below the evidence-based threshold and are not recommended in UK guidance. Option E contradicts current evidence that fluoride toothpaste is effective and safe from tooth eruption when used in the correct amount.
