Fluorose dentaire : diagnostic étiologique
Archives De Pediatrie, 2005Resume La fluorose se definit par une alteration des tissus dentaires durs par surcharge en fluor. Cette affection est consecutive a un apport excessif de fluor chez l'enfant pendant l'organogenese des couronnes dentaires. Les instances medicales recommandent, dans un but de carioprotection, un apport total journalier d'agents fluores egal a 0,05 mg ...

Caries Research, 2009
This scanning electron microscopic (SEM) study summarizes observations made on 6 fluorosed, erupted human permanent teeth. As controls, normal permanent teeth were employed. The exterior surface of the fluorosed teeth as well as outer and inner parts of enamel surfaces obtained by breaking were studied without or following short treatment with citric ...

The histology of fluorosed teeth
Archives of Oral Biology, 1961Abstract Teeth from a high fluorine district were investigated by transmitted light, by polarized light, by dark-field illumination, by microradiography and by routine histology after decalcification. Large areas of hypo-mineralization were found in the enamel, the prisms followed an irregular course and the arcade-shape of the dentino-enamel ...

The ultrastructure of fluorosed human dental enamel
European Journal of Oral Sciences, 1974abstract— More than 80 specimens of enamel from 20 ground sections of eight teeth showing severe dental fluorosis have been examined in the transmission electron microscope. The study has shown that the prisms have normal size and form, but are surrounded by large periprismatic gaps. The individual crystals commonly appear in cross sections as regular,

Protein Characterization of Fluorosed Human Enamel
Journal of Dental Research, 1996Despite extensive investigation, the developmental mechanism or mechanisms resulting in dental fluorosis are unknown. Several hypotheses suggest abnormal matrix synthesis, secretion, and delayed and/or defective matrix degradation with retention of enamel protein.
