Which term represents areas where loss of enamel has exposed underlying dentin?

• A. White spots
• B. Brown cavitations
• C. Enamel hypoplasia
• D. Glossy enamel

Answer: (B)

When enamel loss exposes underlying dentin, you’re looking at a cavitated carious lesion. The surface has been breached and dentin becomes visible, often taking on a brown color due to decay and staining. This is what distinguishes a cavitated, dentin-exposing lesion from white spots, which are non-cavitated areas of early enamel demineralization with an intact surface. Enamel hypoplasia is a developmental defect that results in thin or pitted enamel, not necessarily dentin exposure from decay. Glossy enamel describes a smooth, shiny surface without dentin exposure. So, the term that matches areas where enamel loss reveals dentin is brown cavitations.
