A patient's last dental visit was 2 years ago. Current examination reveals interproximal caries. Using the CAMBRA (Caries Management by Risk Assessment) classification, this patient's caries risk index is:

Correct answer: B. Moderate

• A. Incorrect. Extreme/extreme-risk involves very high caries activity (10+ new lesions) or severe systemic risk factors.
• B. CORRECT. Per CAMBRA, a patient with new caries experience (interproximal lesions) and a 2-year gap since their last visit falls into the moderate risk category. This warrants increased recall frequency and preventive measures.
• C. Incorrect. High risk typically involves multiple active lesions, xerostomia, heavy sugar exposure, or special health needs.
• D. Incorrect. Low risk implies no active caries, compliant recalls, and no risk factors. This patient has active interproximal lesions.
