Using CAMBRA, a patient who has developed new interproximal carious lesions over the past two years is assigned which caries risk level?

Correct answer: A. High risk

• A. ✅ CORRECT — Under CAMBRA, ANY new cavitated or radiographically evident interproximal lesion within the preceding three years places the patient at HIGH RISK. Disease indicators outweigh risk factors: an actual lesion means the balance has already tipped toward demineralization.
• B. ❌ Low risk requires no disease indicators, few risk factors, and adequate protective factors.
• C. ❌ Moderate risk applies when risk factors outweigh protective factors but no new lesions have appeared.
• D. ❌ 'Extreme risk' in CAMBRA denotes high risk PLUS severe salivary hypofunction or special needs — no xerostomia is described here.

Note: High-risk protocol: 5,000 ppm fluoride toothpaste daily, chlorhexidine or xylitol as indicated, 3–4 month recall with bitewings, and sealants.
