Everett City Council <br /> October 5, 2011 <br /> Page Four <br /> Sanitiation Foundation and its publication of the NSF 60 standard <br /> for fluoridation chemicals. See: http://fluoride-class- <br /> action.com/wp-content/uploads/NSF-60-excerpts2.pdf.] <br /> [The 2006 NRC Report stated]: Another conclusion is important for <br /> individuals with chronic kidney disease (CKD), page 9, paragraph 1, <br /> "However, a potentially susceptible subpopulation comprises individuals <br /> with renal impairments who retain more fluoride than healthy people <br /> do." <br /> Note that reduction of the MCLG of 4 ppm would not affect the practice <br /> of fluoridation of water at approximately 1 ppm. <br /> [This is incorrect. The 2006 NRC Report makes it clear that the <br /> MCLG of 4 ppm is a rule requiring REMOVAL of naturally <br /> occurring calcium fluoride when it exceeds that level, not an <br /> authorization add any amount of silicofluoride. Calcium fluoride is <br /> less harmful than silicofluoride. See: <br /> http://www.nap.edu/openbook.php?record id=11571&page=1.1 <br /> The major benefit of water and dental products containing fluoride is the <br /> prevention of dental caries in people of all ages. <br /> Mechanisms through which fluoride provides this benefit include a <br /> systemic effect due to the replacement of hydroxyl ions in hydroxapatite <br /> by fluoride ions during tooth development in children during enamel <br /> formation, a topical effect to remineralize teeth after bacterial <br /> demineralization, and a topical effect to inhibit bacterial acid release. <br /> Dental or enamel fluorosis is a hypomineralization of the enamel surfact <br /> of the tooth that develops in children 8 years old and younger exposed to <br /> excess fluoride levels from any source during critical periods of tooth <br /> development. <br /> [Articles on the CDC website reject this theory. See: <br /> http://www.cdc.gov/mmwr/preview/mmwrhtml/mm4841al.htm; <br /> http://fluoride-class-action.com/wp-content/uploads/caries- <br /> research-systemic-versus-topical-fluoride.pdf; <br /> This [dental fluorosis] affects the appearance of the teeth. Milder forms <br /> are primarily cosmetic, but may have effects on self-esteem. Severe forms <br /> include pitting of the enamel. <br />
