The presence of one or more decayed (non-cavitated & cavitated lesions), missing (due to caries), or filled tooth surfaces in any primary tooth in a child under the age of 6 defines which condition?

• A. Early childhood caries (ECC)
• B. Severe early childhood caries (S-ECC)
• C. Rampant caries
• D. Caries experience index

Answer: (A)

The main idea here is recognizing a pattern of decay in very young children. Early childhood caries is defined as the presence of one or more decayed (including non-cavitated) or missing due to caries, or filled tooth surfaces in any primary tooth in a child younger than six. This definition emphasizes that even early, non-cavitated lesions count toward the diagnosis and that it applies specifically to the primary dentition of children under six.

This sets ECC apart from the other terms. Severe early childhood caries describes a more extreme level of disease with stricter criteria, not just any one decayed, missing, or filled surface. Rampant caries refers to widespread decay occurring rapidly, often in multiple teeth, which can happen in various age groups and dentitions and isn’t defined solely by the under-six primary-tooth criterion. The caries experience index is a measure of caries history (overall decayed, missing, and filled surfaces over the dentition) and isn’t restricted to primary teeth in very young children.

So, the scenario matches Early Childhood Caries because it uses the specific age window and the focus on primary teeth with any affected surfaces.
