Abstract
Objective: To further understand the effect of anti—fluoride water on intellectual development of children and dental fluorosis in drinking water-type of endemic fluorosis area Pucheng county Shaanxi province.
Methods: Two hundred 8 to 12 years old children were randomly selected in endemic fluorosis area with changed water or unchanged water, in 2009 in Pucheng county Shaanxi province. Intelligence quotient (IQ) of children was measured by Raven’s test. Children’s dental fluorosis was examined by Dean’s classification scheme?
Results: The rates of child dental fluorosis in changed water and unchanged water endemic fluorosis areas were 28. 50% (57/200), 87.88% (203/231), respectively, the difference was statistically significant (x2=159.19, P <0.01), while dental fluorosis indices were 0.57, 1.97, was marginal, moderate epidemic. Children with IQ above 90 was accounted for 89.5% (179/200), 91.5% (183/200) in changed water and unchanged water endemic fluorosis area respectively, the difference was not significant (x2=0.46, P >0.05).
Conclusions: Changed water may decrease the incidence of child dental fluorosis, but has no obvious effect on children’s IQ development in endemic fluorosis area.

A preliminary investigation of the IQs of 7–13 year old children from an area with coal burning-related fluoride poisoning.
The Chinese Binet IQ Test was used to investigate the IQs of 7–13 year- old children suffering from dental fluorosis, living and attending school in an area with coal burning-related fluoride poisoning. The average IQ of these children was found to be markedly lower than in the control area, and

Research on the effects of fluoride on child intellectual development under different environments
Goal: To study the effects of the fluoride and iodine content of drinking water on child intellectual development and the interaction between the two factors and also the relationship of educational factors to such development. Methods: The subjects of the investigation were 8- to 14-year-old children randomly selected from endemic areas as well

Fluoride Affects Learning & Memory in Animals
An association between elevated fluoride exposure and reduced intelligence has now been observed in 65 IQ studies. Although a link between fluoride and intelligence might initially seem surprising or random, it is actually consistent with a large body of animal research. This animal research includes the following 45 studies (out

Fluoride: Developmental Neurotoxicity.
Developmental Neurotoxicity There has been a tremendous amount of research done on the association of exposure to fluoride with developmental neurotoxicity. There are over 60 studies reporting reduced IQ in children and several on the impaired learning/memory in animals. And there are studies which link fluoride to Attention Deficit Hyperactivity Disorder. Teaching

Fluoride's Effect on Fetal Brain
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
