What is the first principle of minimal intervention?

• A. Remineralization for early lesions
• B. Reduction in cariogenic bacteria to prevent future carious lesions
• C. Repairing rather than replacing defective restorations
• D. Early diagnosis/Caries Risk Assessment

Answer: (D)

In minimal intervention dentistry, the starting point is identifying problems early and assessing a patient’s caries risk. Detecting lesions while they’re still reversible and understanding the factors that raise a person’s risk lets you tailor a prevention-centered plan from the outset. This approach guides everything that follows: applying remineralization strategies (like fluoride or sealants), prioritizing non-invasive care, and choosing closer monitoring or preventive measures based on the individual’s risk profile. If you don’t diagnose early or assess risk, you’re missing the opportunity to halt decay with conservative methods and may end up needing more invasive restorations later.

Remineralization is a powerful tool, but it relies on catching the problem early and knowing who will benefit most from preventive care. Reducing cariogenic bacteria and other measures are important components of management, yet they don’t establish the initial, proactive plan the way early diagnosis and risk assessment do. Restoring or repairing are appropriate when lesions have progressed beyond reversible stages, which is why they’re not the first step in the MID approach.
