It's simple: If there were NO optimally-fluoridated water and people STILL got fluorosis, LOGIC concludes that fluoridated water is not at-fault.....but THOSE OTHER SOURCES.
Any further argument from you is just trolling due to butthurt.
Stevie Wonder can see that YOU LOSE.
are you seriously trying to postulate that water fluoridation does not contribute to excessive fluoride intake for anyone in the united states based on
this one study? the STUDY itself doesn't even conclude that lol.
But let's take a closer look at this "groundbreaking" study you're basing your entire argument on:
http://www.ncbi.nlm.nih.gov/pubmed/10860326
Abstract
BACKGROUND:
The author conducted research to determine attributable risk percent estimates for mild-to-moderate enamel fluorosis in two populations of middle-school-aged children.
METHODS:
The author recruited two groups of children 10 to 14 years of age.
One group of 429 had grown up in nonfluoridated communities;
the other group of 234 (for a whopping total of 663 kids
)had grown up in optimally fluoridated communities. Trained examiners measured enamel fluorosis using the Fluorosis Risk Index
and measured early childhood fluoride exposure using a questionnaire completed by the parent. (a questionnaire breh?
)The author then calculated attributable risk percent estimates, or the proportion of cases of mild-to-moderate enamel fluorosis associated with exposure to specific early fluoride sources, based on
logistic regression models
RESULTS:
In the nonfluoridated study sample, sixty-five percent of the enamel fluorosis cases were attributed to fluoride supplementation under the pre-1994 protocol. An additional 34 percent were explained by the children having brushed more than once per day during the first two years of life. In the optimally fluoridated study sample, 68 percent of the enamel fluorosis cases were explained by the children using more than a pea-sized amount of toothpaste during the first year of life, 13 percent by having been inappropriately given a fluoride supplement, and 9 percent by the use of infant formula in the form of a powdered concentrate.
CONCLUSIONS:
Enamel fluorosis in the nonfluoridated study sample was attributed to fluoride supplementation under the pre-1994 protocol and early toothbrushing behaviors. Enamel fluorosis in the optimally fluoridated study sample was attributed to early toothbrushing behaviors, inappropriate fluoride supplementation and the use of infant formula in the form of a powdered concentrate.
CLINICAL IMPLICATIONS:
By advising parents about the best early use of fluoride agents, health professionals play an important role in reducing the prevalence of clinically noticeable enamel fluorosis.

stop it fam this is hardly definitive. there's no way you can reach
YOUR conclusion from
THIS study.
that's almost worse than when you tried to refute a harvard study with a blog post earlier in the thread
plus, how can you
logically argue that water fluoridation doesn't contribute to excessive fluoride intake when it's one of the major sources we get our ingested fluoride from?
and the final death blow to your theory: if water fluoridation doesn't play a role in excessive fluoride intake, then why would the government lower water fluoridation levels in their battle to curb excessive fluoride intake?
http://nypost.com/2011/01/07/us-government-wants-to-lower-level-of-fluoride-in-drinking-water/
ATLANTA — Fluoride in drinking water — credited with dramatically cutting cavities and tooth decay — may now be too much of a good thing. It’s causing spots on some kids’ teeth.
A reported increase in the spotting problem is one reason the federal government will announce Friday it plans to lower the recommended limit for fluoride in water supplies — the first such change in nearly 50 years.

the government wouldn't lower the fluoride levels in the water if the fluoride levels in the water weren't contributing to excessive fluoride intake. see how basic that is?
so as you can see funkdoc... you lose
