Which statement describes the relationship between enamel defects and ECC risk?

• A. No association
• B. Increased risk but not substantial
• C. Substantially increased risk of ECC
• D. Decreased risk

Answer: (C)

Enamel defects create rough, porous surfaces that trap plaque and fermentable sugars. Those surfaces provide niches where cariogenic bacteria can thrive, and acids can diffuse more easily into enamel, so the demineralization process kicks in more readily. In early childhood, this combination leads to a higher likelihood and faster progression of decay when caries risk is present, so children with enamel defects show a substantially higher risk of ECC. While not every child with defects will develop ECC, the overall association is strong, not minimal. The other options don’t fit because the defects don’t protect against caries, and the increase in risk is more than small.
