Dean's Fluorosis Index scoring 1 indicates?

• A. Very mild = white areas affecting <25% of tooth surface
• B. No sign of fluorosis
• C. Questionable = few white flecks or spots
• D. Moderate = all tooth surfaces show white areas

Answer: (A)

In Dean's Fluorosis Index, very mild fluorosis means only small white opacities on the enamel that involve less than a quarter of the tooth surface. This describes minimal, subtle changes that are not widespread, which is exactly what the option labeled as very mild conveys. It’s more than no fluorosis, but far less than moderate or severe involvement where extensive white areas cover larger portions or all surfaces. The term questionable is used in some contexts for uncertain or minimal changes, but the standard description for this level is white areas affecting less than 25% of the surface.
