As of May , a total of 73 studies have investigated the relationship between fluoride and human intelligence. Of these investigations, 65 studies. modified with Ce(SO 4)2•4H 2 O, Al(NO 3) 3 •9H 2 O and ZrOCl 2 •8H 2 O. Ce- Ex has somewhat higher defluoridation capac ity than others (i.e. mg F - /kg). Fluoride in drinking water has a profound effect on teeth and bones. Fluoride displaces hydroxide ions from hydroxyapatite, Ca 5 (PO 4) 3 OH, the principal mineral constituent of teeth (in particular the enamel) and bones, to form the harder and tougher fluoroapatite, Ca 5 (PO 4) 3 F. Up to a small level this strengthens the enamel. However, fluoroapatite is an order of magnitude less soluble. Pakistan is also suffering from F − contamination problem (Farooqi, ).A study carried out by Rasool et al. () at 29 large cities of Pakistan reported that 34% of the cities exhibited F − levels more than mg/L while Lahore, Quetta and Tehsil Mailsi were observed having maximum values of , , mg/L, respectively. Another study (Tahir and Rasheed, ) was carried out.
No. Fluoride in water at the recommended level is not toxic according to the best available scientific evidence. Toxicity is related to dose. While large doses of fluoride could be toxic, it is important to recognize the difference between the effect of a massive dose of an extremely high level of fluoride versus the fluoride level currently recommended for public water systems.

Goal: The aim of this study is to determine the effects of improving the health status of teeth after six months treatment with the use of topical fluoridation % NaF, and the level and quality of the impact of treatment with chemical % NaF on the dental health of children at age from 8 to 15 years, in relation to gender and chronological age. The Dean Study National Pure Water Association, in its response to the UK Department of Health’s (DoH) consultation on fluoridation proposals, included the critique – The Dean Study, from the book – The Case Against Fluoride (left).The Dean Study demolishes the very foundation of fluoridation and is reproduced below.
But the claim that Onehunga’s water is “fluoride-free” motivated me to check out the published data for fluoride in the Onehunga water. This graph summarises the data from reports covering the years – (a single report covered ): So, Onehunga water is not “fluoride . The optimal fluoride level in drinking water is to ppm, an amount that has been proven beneficial in reducing tooth decay. Naturally occurring fluoride may be below or above these levels in some areas. Under the Safe Drinking Water Act (Pub L No. ), the EPA requires notification by the water supplier if the fluoride level.  John Yiamouyiannis and Dean Burk, “Fluoridation of public water systems and cancer death rates in humans,” presented at the 57th annual meeting of the American Society of Biological Chemists, and published in Fluoride, Vol. 10, No. 3, , pp. For children living in areas where the fluoride level in drinking water is to ppm, some children should take fluoride supplements as follows: mg daily for children years and
