Demineralized sections of fluorinated bones and teeth have been studied by autoradiography following in vitro uptake of Ca⁴⁵ or S³⁵O₄.

The portions of tissue which do not become mineralized (cartilage, prebone, predentine, and precementum) show an increased Ca⁴⁵ uptake apparently related to an increase in chondroitin sulfate content in fluorosis.

The tissues from the fluoride-fed animals show an increase of in vitro uptake of sulfur in the tissues which become mineralized (bone, dentine, cementum).
