Abstract
Objective: To investigate the relationship between age, dental fluorosis and intelligence in children aged 8-12 in coal-burning fluorosis (CBF) area, Guizhou province.
Methods: A cross-sectional study was conducted to investigate the prevalence of dental fluorosis and intellectual level in 284 children (n=167 for CBF area, n=120 for control are) aged 8- 12 in Mar., 2015. The difference of intelligence level with different levels of dental fluorosis were analyzed.
Results: The prevalence rate of dental fluorosis of children in the endemic fluorosis area was 53.9%, which was significantly higher than that in the control (P<0.011), the dental fluorosis index was 0.59, which meant the area was an edge of epidemic area of endemic fluorosis. The standard score of Raven’s Standard Progressive Matrices (RSPM) of children in endemic area was lower than that in the control (Z=3.124, P=0.002). The intelligence level in endemic area was lower compared with the control and showed a significant difference in 12- year old group (Z=3.244 , P=0.001), no signif1cant relationship between intelligence level and levels of dental fluorosis was seen (H=5.057, P=0.281) . However, the degree of intelligence level negatively c0rrelated with age (r=-0.232, P=0.003).
Conclusion: The intelligence level of children livng in the endemic fluorosis area is lower and more further research need to be done to show the reason.

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

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

Dental Fluorosis: The "Cosmetic" Factor
Any condition that can cause children to be embarrassed about their physical appearance can have significant consequences on their self-esteem and confidence. Researchers have repeatedly found that "physical appearance [is] the best predictor of self-esteem" in adolescents, (Harter 2000) and that facial attractiveness, particularly the appearance of one's teeth, is a

Mechanisms by Which Fluoride Causes Dental Fluorosis Remain Unknown
When it comes to how fluoride impacts human health, no tissue in the body has been studied more than the teeth. Yet, despite over 50 years of research, the mechanism by which fluoride causes dental fluorosis (a hypo-mineralization of the enamel that results in significant staining of the teeth) is not

Dental Fluorosis Impacts Dentin in Addition to Enamel
Dental fluorosis is a mineralization defect of tooth enamel marked by increased subsurface porosity. The enamel, however, is not the only component of teeth that is effected. As several studies have demonstrated, dental fluorosis can also impair the mineralization of dentin as well. As noted in one review: "The fact that
