S-ECC is defined as any sign of smooth-surface caries in a child younger than how many years old?

• A. Under 2 years
• B. Under 4 years
• C. Under 3 years
• D. Under 5 years

Answer: (C)

S-ECC stands for Severe Early Childhood Caries, a pattern of rapidly progressing decay seen in very young children. The defining criterion uses the age cutoff of younger than 3 years and looks at any sign of smooth-surface caries. Smooth surfaces (like the front and side surfaces of teeth) are less commonly affected in normal, slow early decay, so finding caries signs there in a child under 3 signals an unusually aggressive process that needs prompt attention. Why this age limit matters: by setting the threshold at under 3 years, clinicians quickly identify children who are at high risk and may require intensive prevention and treatment measures to prevent widespread decay. The other ages don’t match this established definition, either narrowing the scope too much or broadening it beyond the recognized severe pattern.
