Diagnostic and Treatment The adequate diagnosis of fluorosis requires inspection of dry and clean dental surfaces, under a good light source. The clinical appearance of mild dental fluorosis is characterized
by bilateral, diffuse (not sharply demarcated), opaque, and white striations that run horizontally across
the enamel. The opacities may coalesce to form white patches. In the more severe forms, enamel may become
discolored and/or pitted. Upon eruption into the mouth, fluorosed enamel is not discolored, the stains develop
over time due to the diffusion of exogenous ions (ex, iron and copper) into the abnormally porous enamel.
