Answer the question

Caries Risk Assessment in Practice

Caries is now understood as an ecological disease: a dysbiotic shift in the oral microbiome driven by frequent fermentable carbohydrate exposure, reduced salivary flow, and poor buffering capacity, rather than a simple infection by Streptococcus mutans. Caries risk assessment (CRA) tools such as CAMBRA use biological, protective, and behavioral factors to place patients in low, moderate, high, or extreme risk categories and tailor prevention. A 16-year-old attends for a routine examination and you find four new incipient lesions in the posterior pits and fissures. How does a CRA framework change what this visit is for, and how would you apply it with this patient?

Likely follow-ups
1

His assessment shows high risk: frequent sugary drinks, well water with no fluoride, visible plaque and reduced saliva. What do you prioritize over the next six months?

2

His parent says everyone in the family drinks soda and they do not all get cavities. How do you handle that conversation?

3

When would silver diamine fluoride be a better choice than sealants or restoration for these lesions, and what is the trade-off?

What strong answers do
Reveal the benchmark

Hidden so they don't bias your answer. Score yourself first, then reveal them to compare.

  • The ecological model reframes the dentist from drill-and-fill operator to disease manager: a routine examination is also a risk stratification encounter, and four incipient lesions in a 16-year-old are a signal to find what is feeding the disease rather than simply to book four restorations.
  • Follow the CAMBRA logic: reduce the drivers (counsel on the frequency of fermentable carbohydrates and acid beverages, since frequency matters more than amount), build protective factors (5,000 ppm fluoride toothpaste, in-office varnish, sealants, closing a well-water fluoride gap), then reassess at short intervals and restore only lesions that progress.
  • Know the SDF trade-off: it arrests active lesions without anesthesia or drilling but permanently stains them black and needs explicit consent; for incipient pit-and-fissure lesions in a cooperative teenager, sealants and remineralization are usually the better first move.
