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.

"Conclusions: Fewer studies have been published recently. More of these have investigated effect at the multi-community, state or even national level. The dmf/DMF index remains the most widely used measure of effect. % CR were lower in recent studies, and the 'halo' effect was discussed frequently. Nevertheless, reductions were still substantial. Statistical control for confounding factors is now routine, although the effect on per cent reductions tended to be small. Further thought is needed about the purpose of evaluation and whether measures of effect and study design are appropriate for that purpose."

Effectiveness of water fluoridation in caries prevention.

Note: "reductions were still substantial" and "Statistical control for confounding factors is now routine"

Snapshots of data, as antifluoridationists constantly attempt to use, do not control for any confounding factors.

Steve Slott 

Is this an attempt to provide a reference for your claims? Is this one of your "long list" of studies? If you need a refresher: 

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." 

PM: You're being asked - again - to provide just 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..
