JADA Study Proves Fluoridation is Money down the Drain

Children's cavity rates are similar whether water is fluoridated or not, according to data published in the July 2009 Journal of the American Dental Association by dentist J.V. Kumar of the NY State Health Department (1).

In 2008, New York City spent approximately $24 million on water fluoridation ($5 million on fluoride chemicals)(1a). In 2010, NYC's fluoride chemicals will cost $9 million (1b).

Fluoride in water at "optimal" levels (0.7 – 1.2 mg/L) is supposed to reduce tooth decay without creating excessive fluorosis (fluoride-discolored and/or damaged teeth). Yet cavities are rampant in NY's fluoridated populations (1c).

Attempting to prove that fluorosed teeth have fewer cavities, Kumar uses 1986-1987 National Institute of Dental Research (NIDR) data which, upon analysis, shows that 7- to 17-year-olds have similar cavity rates in their permanent teeth whether their water supply is fluoridated or not (Table 1).

In 1990, using the same NIDR data, Dr. John Yiamouyiannis published equally surprising results in a peer-reviewed journal. He concluded, "No statistically significant differences were found in the decay rates of permanent teeth or the percentages of decay-free children in the F [fluoridated], NF [non-fluoridated], and PF [partially fluoridated] areas." (2).

Kumar divided children into four groups based on their community's water fluoride levels:

Less than 0.3 mg/L where 55.5% had cavities
From 0.3 to 0.7 mg/L where 54.6% had cavities
Optimal 0.7 to 1.2 mg/L where 54.4% had cavities
Over 1.2 mg/L where 56.4% had cavities

"Dr. Kumar's published data exposes more evidence that fluoridation doesn't reduce tooth decay," says attorney Paul Beeber, President, New York State Coalition Opposed to Fluoridation, Inc.

"It's criminal to waste taxpayers' money on fluoridation, while exposing entire populations unnecessarily to fluoride's health risks, especially when local and state governments are attempting to balance budgets by cutting essential services," says Beeber.

STATISTICAL ANALYSIS OF KUMAR'S DATA
Kumar's data: 6,720 children came from communities with water fluoride levels less than 0.3 mg/L
54.9% of the 3,921 children without fluorosis had tooth decay = 2,153
60.1% of 1,818 children with questionable fluorosis had tooth decay = 1,093
49.3% of 981 with fluorosis present had cavities = 484
TOTAL 6,720 TOTAL WITH CAVITIES 3,730
3,730 is 55.5% of 6,720 Therefore, 55.5% had cavities.

***

1,979 children tested lived in communities with from 0.3 to 0.7 mg/L Fluoride
54.7% of 1,084 children with normal teeth have cavities = 593
59% of 507 children with questionable fluorosis have cavities = 299
48.4% of 388 children with fluorosis present had cavities = 188
TOTAL 1,979 TOTAL WITH CAVITIES 1,080
1,080 is 54.6% of 1,979. Therefore, 54.6% of children living in 0.3 to 0.7 mg/L fluoridated communities have tooth decay

***

7,177 lived in optimally fluoridated areas (0.7 – 1.2 mg/L)
54.1% of the 2875 children without fluorosis had tooth decay = 1,555
53.8% 2493 children with questionable fluorosis had tooth decay = 1,341
55.7% of 1809 with fluorosis present had cavities = 1,008
TOTAL 7,177 TOTAL WITH CAVITIES 3,904
3914 is 54.4% of 7177. Therefore 54.4% of children living in optimally fluoridated areas had cavities

***

813 children living in areas with greater than 1.2 mg/L Fluoride in their water
52.3% of 248 children with normal teeth had cavities = 130
64.1% of 236 children with questionable fluorosis had cavities = 151
54% of 329 children with fluorosis had cavities = 178
TOTAL 813 TOTAL WITH CAVITIES 459
56.4% of 813 children is 459 . Therefore 56.4% of children living in areas with more than 1.2 mg/L fluoride in the water have cavities
