Which factor is commonly considered when selecting MID strategies for a patient?

• A. Tooth location
• B. Patient cooperation
• C. Caries risk
• D. Moisture control

Answer: (C)

Caries risk is the main factor guiding MID strategies because it tells you how aggressively to intervene and which techniques will best arrest or prevent decay while preserving tooth structure. If a patient is at high caries risk, the plan leans toward noninvasive or minimally invasive methods that remineralize and control the disease process—such as sealants, fluoride therapies, silver diamine fluoride, and using materials like glass ionomer that release fluoride and tolerate less-than-perfect isolation. It also supports selective or partial caries removal and restorations designed to arrest decay with minimal drilling. For a patient at lower risk, the approach can be more conservative, focusing on monitoring and preventive measures with limited operative intervention. This risk-based decision-making helps tailor MID to the individual rather than applying a uniform technique.
