[Dental fluorosis: etiological diagnosis].
Dental fluorosis is defined by an alteration of dental hard tissues and occurs when fluoride intakes are excessive. Medical authorities recommend a total daily consumption of 0.05 mg/kg of fluoride, without exceeding 1 mg.


METHODS
The two reported clinical observations confirm that fluorosis is a consequence of excessive fluoride intakes. Etiological diagnosis allows a better understanding of this pathology. In the majority of the cases, dental fluorosis can be avoided.


CONCLUSIONS
Dental fluorosis is the sole risk of fluoride use, but it is not a fate. It does not constitute a problem of public health in France and the benefits/risks ratio is widely in favour of the use of fluoride.
