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.

Relationship between Drinking Water Fluoride and Intelligence Quotient in Egyptian School Children.
Background: Fluoridation of drinking water, despite being regarded as one of the top ten public health achievements of the twentieth century, has remained a much more debated concept. Excessive fluoride intake during infancy and early childhood causes a number of irreversible structural and functional changes in the CNS leading to

Investigation and Analysis of Children’s IQ and Dental Fluorosis in a High Fluoride Area
Objective: To understand the relationship of dental fluorosis and IQ among children in a high fluoride area and further study the harm of high fluoride to the human body. Method: High fluoride areas (from drinking water) in Qi County were selected as the site of investigation. The subjects of the study

The effect of fluorine on the level of intelligence in children.
Recently, many researchers and scholars have studied about the effects of the trace element, iodine, on the level of intelligence in children. However there has been little coverage or noise about the same effect of fluorine on children. For this purpose we have performed some research and the results are as follows.

The influence of fluoride in drinking water on the incidence of fluorosis and intelligence of elementary school students in Palu City.
Abstract Objective This research aims to know the influence of fluoride in drinking water towards Fluorosis and the Intelligence Level of Elementary School Students in Palu City. Method This cross-sectional study was performed through descriptive analysis on 100 students aged 6–12 years old selected by stratified random sampling from two different areas with different

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 & IQ: 76 Studies
• As of July 18, 2022, a total of 85 human studies have investigated the relationship between fluoride and human intelligence. • Of these investigations, 76 studies have reported that elevated fluoride exposure is associated with reduced IQ in humans. • The studies which reported an association of reduced IQ with exposure

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

Fluoride's Direct Effects on Brain: Animal Studies
The possibility that fluoride ingestion may impair intelligence and other indices of neurological function is supported by a vast body of animal research, including over 40 studies that have investigated fluoride's effects on brain quality in animals. As discussed by the National Research Council, the studies have consistently demonstrated that fluoride, at widely varying concentrations, is toxic to the brain.
