Dean's Fluorosis Index score 3 corresponds to which description?

• A. Moderate = all tooth surfaces show white areas with some brown stains
• B. Very mild = white flecks
• C. Mild = white opacities affecting <50%
• D. Severe = brown stains, pits, and surface damage on most or all teeth

Answer: (A)

Dean's Fluorosis Index grades enamel changes from normal to severe based on how widespread the white opacities are and how much staining appears. A score of three corresponds to moderate fluorosis, which is described as white opacities across all tooth surfaces with some brown staining. This reflects diffuse involvement of the enamel rather than localized white flecks or pits. In the progression, mild shows less extensive opacities, and severe features pits and substantial enamel breakdown with darker staining. So the description of white areas on all surfaces with some brown stains best fits the moderate level.
