Which of the following is listed as the secondary prevention concept?

• A. Disease prevention through vaccination
• B. Oral prophylaxis for gums
• C. Promotion of healthy behaviors
• D. Early detection and prompt intervention-- before significant damage occurs

Answer: (D)

Secondary prevention focuses on finding disease early and intervening promptly to prevent it from getting worse. In dentistry, that means screening and diagnostics that detect caries or periodontal disease before symptoms appear, followed by timely treatment to halt progression and limit damage. The option describing early detection and prompt intervention before significant damage occurs fits that idea exactly. By contrast, vaccination and promoting healthy behaviors are aimed at preventing disease from starting (primary prevention), and while prophylaxis helps maintain oral health, it isn’t fundamentally about catching disease early and stopping its course.
