In MID, ART should be considered when what condition is present?

• A. If dentin is not involved
• B. If there's a big occlusal dentin involvement but not near pulp
• C. If caries risk is low
• D. If dentin is involved in caries

Answer: (D)

When caries has reached dentin, ART fits the principles of minimally invasive dentistry. Dentin involvement means the decay can be managed by removing the soft, affected dentin with hand instruments and sealing the cavity with glass ionomer cement. This conservative approach preserves tooth structure, reduces patient discomfort, and the glass ionomer provides fluoride release to help arrest remaining decay. If caries stays limited to enamel or involves only superficial dentin, other preventive or less invasive strategies may be suitable, but once dentin is involved, ART offers an effective, atraumatic restoration aligned with MID goals.
