Abstract
The aim of this work was to evaluate the impact of fluoride exposure on the prevalence of dental caries and the intellectual ability of children.
Method: In this cross-sectional study, 161 children from 9 to 10 years of age were evaluated. The concentration of fluoride in drinking water and urine was analyzed individually. Oral health status regarding dental caries and dental fluorosis was assessed. The intellectualability of children was evaluated through the Raven’s Colored Progressive Matrices. In addition, variables such as diet, oral hygiene, body mass index, and socioeconomic status were included.
Results: There was a negative relationship between the DMFT index and the level of dental fluorosis. In the logistic regression analysis, a water fluoride exposure above 1.0 mg/L showed less risk of dental caries (OR = 0.41; p=0.025). Parental education level lower than high school raised significantly the risk of dental caries (OR = 2.81; p=0.036). No relationship was found between intellectual ability and fluoride exposure variables such as, dental fluorosis, levels of fluoride in drinking water and urine, and exposure dose.
Conclusion: The results suggest that exposure to fluoride reduces the prevalence of dental caries, but no association was found to the intelligence of children.

Threshold effects of moderately excessive fluoride exposure on children's health: A potential association between dental fluorosis and loss of excellent intelligence.
Highlights Childhood fluoride exposure was inversely associated with dental health and IQ. Threshold and saturation effects for aforementioned associations existed. Moderate fluoride exposure was mainly related to excellent intelligence loss. Dental fluorosis may be useful to reflect excellent intelligence loss. BACKGROUND: Excessive fluoride exposure is associated with adverse health outcomes, but

Critical Windows of Fluoride Neurotoxicity in Canadian Children.
Highlights The association between fluoride and performance IQ (PIQ) significantly differed across prenatal, infancy, and childhood exposure windows collapsing across child sex (p = .001). The strongest association between fluoride and PIQ was during the prenatal window, B = -2.36, 95% CI: -3.63, -1.08; the association was also significant

Arsenic and fluoride co-exposure through drinking water and their impacts on intelligence and oxidative stress among rural school-aged children of Lahore and Kasur districts, Pakistan.
Arsenic (As), and fluoride (F-) are potent contaminants with established carcinogenic and non-carcinogenic impacts on the exposed populations globally. Despite elevated groundwater As and F- levels being reported from various regions of Pakistan no biomonitoring study has been reported yet to address the co-exposure impact of As and F- among

OP V – 2 Prenatal fluoride exposure and neurobehavior among children 1–3 years of age in Mexico
Background/aim Recent studies report an inverse association between fluoride (F) exposure and IQ in children, but few included individual measures of exposure or assessed associations with prenatal exposure using a prospective study design. Methods This study utilised the Early Life Exposures in Mexico to Environmental Toxicants (ELEMENT) birth cohort and archived pregnancy samples

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 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'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.

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
