Fluoridation and the occurrence of Down's syndrome
The prevalence rates of Down's syndrome at birth were compared for Massachusetts residents ingesting fluoridated and non-fluoridated water. The observations included nearly all children born alive with Down's syndrome in Massachusetts during the 17-year period 1950-1966. A rate of 1.5 cases per 1000 births was found for fluoride-related births and

[New researches on mongolism related to the disease producing role of fluorine].
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

Association of Down's syndrome and water fluoride level: a systematic review of the evidence
Background: A review of the safety and efficacy of drinking water fluoridation was commissioned by the UK Department of Health to investigate whether the evidence supported a beneficial effect of water fluoridation and whether there was any evidence of adverse effects. Down's syndrome was one of the adverse effects reported. The

Fluoride-linked down syndrome births and their estimated occurrence due to water fluoridation
Down syndrome (DS) birth rates (BR) as a function of maternal age exhibit a relatively flat linear regression line for younger mothers and a fairly steep one for older mothers with the second line intersecting the first line a little above maternal age 30. Consequently, overall DS-BR for all maternal

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
