Enamel defects may appear as changes in translucency, texture, or color and increase risk for early childhood caries. Which term describes these conditions?

• A. Enamel defects
• B. White spot lesions
• C. Fluorosis
• D. Hypoplasia

Answer: (A)

Enamel defects describe a range of abnormalities in the enamel’s appearance or structure. When enamel isn’t formed or mineralized normally, it can show as changes in translucency (opacities), texture (rough or pitted surfaces), or color (white, yellow, or brown spots). These alterations can create rough, porous areas that harbor plaque and make the enamel more susceptible to demineralization and early childhood caries. While white spot lesions are a specific early caries sign and fluorosis or hypoplasia are particular types of enamel changes, the broad term that covers all these presentations is enamel defects.
