Explanation lettering: D = shown as A · E = shown as B · A = shown as C · B = shown as D · C = shown as E

Delivering Better Oral Health (UK government guidance) recommends that fluoride varnish (2.2% NaF) be applied twice yearly to children aged 3–6 years as routine preventive care. For children at higher risk of caries, application may be recommended at two or more times per year. Option A correctly identifies both the frequency (twice yearly) and the specific concentration (2.2% NaF). Options B and C underestimate the recommended frequency. Option D (four times yearly) reflects current SDCEP specialist guidance but does not align with the stated reference source. Option E is incorrect as fluoride varnish is applied routinely for prevention, not reactively after caries develops.
