False Statement # 9 by Steve Slott, DDS

SLOTT: "It is futile to attempt to make any kind of assessment on effectiveness water fluoridation or any of the numerous other variables involved in formation of dental decay without controlling for these factors. There are countless peer-reviewed scientific studies which demonstrate the effectiveness of water fluoridation. i will gladly provide you with a list of some of them if you so desire."

Question asked by Paul Melters:

Okay, why don't you post one of those "countless studies" which demonstrate the effectiveness of water fluoridation and which has accounted for confounding factors such as race, gender, age, total intake, tooth eruption, brushing and other oral hygiene factors, socio-economic status, etc.? Let's have a look at them.

Here you go, Paul. As I've demonstrated to you already, statistical control for confounding factors is routine in these studies. I'm not sure what it is you're having such a time in understanding about all of this, but maybe this will help you some. Just let me know if you want any more proof of effectiveness and I'll be glad to accommodate.

Results  
Children from every age group had greater caries prevalence and more caries experience in areas with negligible fluoride concentrations in the water (<0.3 parts per million [ppm]) than in optimally fluoridated areas (≥0.7 ppm). Controlling for child age, residential location, and SES, deciduous and permanent caries experience was 28.7% and 31.6% higher, respectively, in low-fluoride areas compared with optimally fluoridated areas. The odds ratios for higher caries prevalence in areas with negligible fluoride compared with optimal fluoride were 1.34 (95% confidence interval [CI] 1.29, 1.39) and 1.24 (95% CI 1.21, 1.28) in the deciduous and permanent dentitions, respectively.

CONCLUSIONS:  
Children with severe dental caries had statistically significantly lower numbers of lesions if they lived in a fluoridated area. The lower treatment need in such high-risk children has important implications for publicly-funded dental care.

CONCLUSIONS:  
The survey provides further evidence of the effectiveness in reducing dental caries experience up to 16 years of age. The extra intricacies involved in using the Percentage Lifetime Exposure method did not provide much more information when compared to the simpler Estimated Fluoridation Status method.

Abstract  
The effectiveness of fluoridation has been documented by observational and interventional studies for over 50 years. Data are available from 113 studies in 23 countries. The modal reduction in DMFT values for primary teeth was 40-49% and 50-59% for permanent teeth. The pattern of caries now occurring in fluoride and low-fluoride areas in 15- to 16-year-old children illustrates the impact of water fluoridation on first and second molars.

CONCLUSIONS:  
Data showed a significant decrease in dental caries across the entire country, with an average reduction of 25% occurring every 5 years. General trends indicated that a reduction in DMFT index values occurred over time, that a further reduction in DMFT index values occurred when a municipality fluoridated its water supply, and mean DMFT index values were lower in larger than in smaller municipalities.

No, sorry, there have been no lies on my part. Just more of your delusions, I guess.

Your lies are documented here:

http://fluoridedentalexperts.com/

As far as you pasting a bunch of abstracts above - none of which supply that which was asked from you - well, it just shows that a) you don't understand English very well, or b) you really don't have a clue. 

Slott: "As I've demonstrated to you already, statistical control for confounding factors is routine in these studies. I'm not sure what it is you're having such a time in understanding about all of this, but maybe this will help you some. Just let me know if you want any more proof of effectiveness and I'll be glad to accommodate." 

PM Response. Oh - don't you worry Steve, I understand very well.

Once again - please list the established confounding factors you pretend to know so much about.

Secondly, provide just ONE study - NOT a review of a bunch of studies which have NOT controlled for said established confounding FACTORS.

We just need ONE study - as described below.

Do you understand that? It's very simple!

So - once again:

Provide ONE scientific study which show this effectiveness of water fluoridation, and which has accounted for established confounding factors such as race, gender, age, total intake, tooth eruption, brushing and other oral hygiene factors, socio-economic status, etc..

(And that's not even including "altitude" or "dental fluorosis" which is KNOWN to cause more caries AND more caries intensity. Better save that for another day, wouldn't you say?)
