The acidified-gel artificial caries technique was used to produce in vitro caries-like lesions in fluorosed and sound enamel. Both abraded and unabraded surfaces were exposed to attack. The histological features were similar in fluorosed and non-fluorosed specimens, although the pore volumes in the body of the lesion were much less in fluorosed specimens despite their initial porosity. Where the surface was abraded, greater depth of lesion penetration was noted with no intact surface zone. The surface enamel possibly exerts some protective effect.
