A patient of record returns after 2 years with one new interproximal carious lesion. What is the CAMBRA (Caries Management by Risk Assessment) caries risk classification for this patient?

According to CAMBRA guidelines, a patient of record who presents with any new cavitated or non-cavitated carious lesion at a follow-up visit is automatically classified as at least HIGH risk. New disease indicators — even a single new carious lesion — signal that the balance between cariogenic and protective factors has shifted. This is a disease indicator that definitively places the patient in the high-risk category, regardless of other protective factors. If hyposalivation is also present, the classification rises to extreme risk.
