Exposure to fluoride occurs mainly through drinking water, which may include fluoride from natural sources and fluoride added to prevent tooth decay. Naturally occurring fluoride concentrations can vary substantially, from insignificant to well above the World Health Organization (WHO)-recommended limit of 1.5mg/L (WHO 2006), whereas the concentration in artificially fluoridated water is typically around 0.7mg/L (U.S. Department of Health and Human Services Federal Panel on Community Water Fluor
Conclusions
From the data of this study and the findings of other earlier studies, we can conclude that operating room personnel exposures to WAG are associated with changes in blood levels of IgG and IgM, total lymphocytes, CD4+ and CD8+ subtypes, and accordingly, in CD4:CD8 ratios. It is quite possible these changes would likely be associated with immune dysfunction in these WAG-exposed hosts. As it is not yet clear if this might be reflected as reduced host resistance and/or an increased r
1. Introduction
Fluoride is a widespread environmental pollution, and groundwater is the major source of exposure in which the fluoride concentration can be as high as 35 ppm (Petrone et al., 2013). Fluorosis induced by geological origin is a serious public health concern in 28 nations particularly in India and China (Rafique et al., 2015). In India, 230 districts of 20 states are at risk of a high level of fluoride in drinking water (Srivastava and Flora, 2020). In China, almost all the provi

5. Fluorine (F)
According to some researchers, fluorine is a microelement needed for proper development. However, in the case of this element, it is important to determine its concentration in
the human body, because the difference between the tolerated dose and the toxic dose is very small [110].
Fluorides (F-), the ionic form of fluorine, in trace amounts are essential for the proper development of the bones and the teeth [111]. They stimulate the proliferation of osteoblasts

3.2. Baseline Dental Fluorosis
The proportion of severe dental fluorosis among all women included in this trial was 10.3%; and the proportion of women with moderate dental fluorosis was 29.5% (30.8% in the intervention and 28.2% in the control groups). Overall, more than half, 57.7% (64.1% in the intervention and 51.3% in the control groups) of the study women had very mild to severe dental fluorosis level. There was no statistically significant difference in the proportion of dental fluorosis
