FLUOROSE DENTAIRE
Un désastre dentaire
As both the numbers of Americans and percentage of the population drinking fluoridated water swelled, dental fluorosis also grew, disproportionately and with worse severity in Black and Latino populations.
Dental fluorosis is a defect in the tooth due to cell death during the formative stages. Those with dental fluorosis have higher bone fractures as well as higher rates of learning disabilities. Dental fluorosis is the visible evidence of similar defects due to cytotoxic effects that occur in bones and brains during critical periods of development, i.e. prenatal, infancy and early childhood.
Dental fluorosis is also a leading indicator of higher dental costs as these unattractive and brittle teeth will require costly veneers and crowns in young adulthood. Per 2011-2012 NHANES figures released in 2017, one in five (23%) American teens have brown mottling and perhaps pitting on at least two fluorosed teeth due to childhood exposure.

Conclusion: “There was a difference of 31.6% in dental fluorosis prevalence between 2012-2011 when compared to data from 2002-2001 in adolescents aged 16 and 17 years. The continued increase in fluorosis rates in the U.S. indicates that additional measures need to be implemented to reduce its prevalence.”
Lorsque la fluoration a commencé, les partisans ont promis au public américain que le seul et pire risque du programme était que moins de 10 % des enfants pourraient avoir quelques taches blanches pâles sur leurs dents « résistantes aux caries », ce qui, selon beaucoup, ajouterait un éclat attrayant.
Il convient également de noter que les chercheurs des premiers essais de fluoration ont traité les enfants afro-américains différemment dès le début, écrivant qu’il était de notoriété publique que les Noirs avaient des dents plus solides et plus résistantes à la carie.
Il n'a pas fallu longtemps aux personnes impliquées pour se rendre compte que quelque chose n'allait pas du tout, mais leur réaction à la note de 1962 qui notait des taux élevés de fluorose qui avaient doublé chez les enfants afro-américains a mis l'accent sur la protection du programme de fluoration.
