ADC Practice Question — CMS Risk Assessment & Classification

Based on 18 months of <1 new lesion/year and no progression, what is the new risk classification AND the corresponding recall change?

Q: How are CMS Risk Assessment & Classification questions structured in the ADC written exam?

ADC CMS Risk Assessment & Classification questions present as clinical vignettes requiring management decisions. The correct answer is always traceable to a guideline source.

Q: Should I memorise guidelines word-for-word for CMS Risk Assessment & Classification?

Focus on decision points — when the guideline says X vs Y. The exam tests application, not recitation.

Prevention and cariology questions test evidence-based decision-making — fluoride protocols, caries risk assessment, recall scheduling. This high-difficulty vignette tests your ability to work through clinical details and arrive at the correct management.

A 55-year-old was classified High risk 18 months ago. Since then: zero new lesions, all existing radiolucencies stable (no progression), plaque score improved from 28/36 to 8/36, home care goals achieved (5000 ppm daily, good brushing technique). The dentist reassesses the risk classification and management. Based on 18 months of <1 new lesion/year and no progression, what is the new risk classification AND the corresponding recall change?

A. Remains High — patients cannot be reclassified until all C4 radiolucencies have fully regressed to C0
B. Drops to Low — meeting <1 new/year AND no progression satisfies both Low recall criteria simultaneously
C. Drops to Medium first — then to Low after another period of stability; direct High→Low reclassification is not supported
D. Drops to Low — with recall extending from 3-monthly High to 12 months initially, then potentially 18-24 months

Correct answer: D

Integration: (1) Recall Low criteria (Table 4): <1 new/year AND no progression — BOTH met. (2) No stepwise requirement. (3) Recall change (Table 8): High 3-monthly → Low 12 months then 18-24 months. (4) BW change: 6-monthly → 18-24 monthly. (5) Fluoride: 5000 ppm → 1000 ppm. SOURCE — Evans RW et al. CMS for adults, ADJ 2008;53:83-92, Tables 4, 7, 8

Remy's study tip — Identify the patient’s risk level first, then match the intervention to the risk.
