NEGATORY: Fluoride does NOT provide benefits.

"Swallow Fluoride at Your Own Peril - Study Shows Risks without Benefits"


NEW YORK, Feb. 24, 2011 /PRNewswire-USNewswire/ -- Low-income children who consumed recommended fluoride doses have more fluoride-damaged teeth and high cavity rates, according to research published in the International Journal of Environmental Research and Public Health, January 2011.

Fluoride (hydrofluosilicic acid) is added to U.S. water supplies in a failed effort to reduce tooth decay. However, in Mexico fluoride is added to salt because water fluoride levels are low.

Mexican preschoolers and school-aged children in a low-income area were measured for cavities, fluorosis (fluoride-discolored teeth) and urine fluoride levels.

Despite urinary excretion within an optimal fluoride intake range, 78% of 4- to 5-year-olds and 73% of 11- to 12-year-olds have cavities while 60% of the older children have dental fluorosis.

In this study, dental fluorosis was significantly associated with the amount of toothpaste used, age and frequency of brushing. Three-fourths of the parents used fluoridated salt for cooking.

Fluoride was measured in bottled water, juices, nectars and carbonated drinks (range 0.08 ppm to 1.70 ppm)

The researchers report that "the results of previous studies show that the consumption of fluoridated water in addition to fluoride-containing products may promote an increased development of dental fluorosis lesions, even in people living in regions considered to be non-endemic areas."

"Legislators cavalierly order fluoride into the bodies of American children without considering their individual total fluoride intake, clearly causing potential harm," says attorney Paul Beeber, President, New York State Coalition Opposed to Fluoridation, Inc. "Legislators who vote for fluoridation often base their decision on hearsay and fail to look at the science behind fluoridation."

The researchers stress individual variables be considered before fluoride is administered such as nutritional status, total fluoride ingestion and excretion. Also, environment and geographical factors should be evaluated, including location, weather and altitude.

The CDC admits that fluoride's predominant mode of action is topical and that "(t)he prevalence of dental caries in a population is not inversely related to the concentration of fluoride in enamel, and a higher concentration of enamel fluoride is not necessarily more efficacious in preventing dental caries."

This study adds to a growing body of evidence indicating that fluoride ingestion is ineffective at reducing tooth decay, therefore making water fluoridation an outdated drug delivery system. See: http://www.fluoridealert.org/health/teeth/caries/topical-systemic.html

"Abstract: Objective. The purpose of this study was to evaluate caries and dental fluorosis among Mexican preschoolers and school-aged children in a non-endemic zone for fluorosis and to measure its biological indicators. Methods. DMFT, DMFS, dmft, dmfs, and CDI indexes were applied. Fluoride urinary excretion and fluoride concentrations in home water, table salt, bottled water, bottled drinks, and toothpaste were determined. Results. Schoolchildren presented fluorosis (CDI = 0.96) and dental caries (DMFT = 2.64 and DMFS = 3.97). Preschoolers presented dmft = 4.85 and dmfs = 8.80. DMFT and DMFS were lower in children with mild to moderate dental fluorosis (DF). Variable fluoride concentrations were found in the analyzed products (home water = 0.18–0.44 ppm F, table salt = 0–485 ppm F, bottled water = 0.18–0.47 ppm F, juices = 0.08–1.42 ppm F, nectars = 0.07–1.30 ppm F, bottled drinks = 0.10–1.70 ppm F, toothpaste = 0–2,053 ppm F). Mean daily fluoride excretion was 422 ± 176 μg/24 h for schoolchildren and 367 ± 150 μg/24 h for preschoolers. Conclusions. Data from our study show that, despite values of excretion within an optimal fluoride intake range, the prevalence of caries was significant in both groups, and 60% of the 11- to 12-year-old children presented with dental fluorosis. In addition, variable fluoride concentrations in products frequently consumed by children were found."
