Using the CMS criteria for primary dentition, what risk category applies?
Prevention and cariology questions test evidence-based decision-making — fluoride protocols, caries risk assessment, recall scheduling. This exam-level vignette tests your ability to work through clinical details and arrive at the correct management.
A 4-year-old boy has dmfs = 3, ICDAS codes > 1 on two primary molars, and C1 radiolucencies on two approximal surfaces. He presents as a new patient. Using the CMS criteria for primary dentition, what risk category applies?
- A. Low — C1 radiolucencies are the mildest score and do not elevate risk classification
- B. At-risk — dmfs > 0 with ICDAS > 1 and C1 or greater radiolucencies
- C. At-risk High — any child with dmfs > 0 is classified as High
- D. Medium — no frank cavitation with early radiographic findings only
