Abstract

1) The low incidence of dental caries observed in mongoloid patients led to an investigation of the role of fluorine in this condition.

2) A statistical study of the geographical distribution of mongolism in Wisconsin, Illinois, Idaho, North and South Dakota (U.S.A.) shows a parallelism between the prevalence of this condition and the amount of fluoride in the water supply.

3) A new hypothesis on the pathogenesis of mongolism is proposed: the blockage of an enzymatic system by an inhibitor, such as fluorine, at an early stage of the fetal development.

    Une enquête épidémiologique sur la fréquence du mongolisme dans quelques Etats du Midwest américain nous a permis de mettre en évidence les faits suivants: 1: un parallélisme entre la fréquence du mongolisme et la teneur en fluor de l'eau de boisson; 2: une rareté relative des caries dentaires chez les mongoliens; 3: une

    A new statistical study on the distribution of mongolism in cities in Illinois, United States, from January 1, 1950 to December 31, 1956, permits us to verify an increasing frequency of this affliction associated with the concentration of fluorine in the drinking water. This study follows a preceding inquiry on the

  • Water fluoridation and congenital malformations: no association

    Data based on a total number of 1,387,027 births were used to compare the incidence of selected congenital malformations in fluoridated areas and that in areas where the water supply is deficient in fluoride. The incidence of selected congenital malformations in areas with fluoride supplementation of public water supplies was compared

    It has been claimed that there is a positive association between the frequency of Down syndrome and the fluoridation of drinking water. It has also been suggested that this association is most pronounced in young women. Recent congenital malformations data obtained from birth certificates from large U.S. cities have been

    The human placenta does not prevent the passage of fluoride from a pregnant mother's bloodstream to the fetus. As a result, a fetus can be harmed by fluoride ingested pregnancy. Based on research from China, the fetal brain is one of the organs susceptible to fluoride poisoning. As highlighted by the excerpts
