Correct answer: D — Primary prevention

Community water fluoridation is a primary prevention measure — it aims to prevent disease (dental caries) before it occurs in the population. Primary prevention includes health promotion (education, oral hygiene instruction) and specific protection (fluoridation, sealants, vaccination). Secondary prevention involves early detection and treatment (screening, bitewing radiographs for early caries detection). Tertiary prevention aims to reduce disability and rehabilitate (prosthetic rehabilitation, treatment of advanced disease).
