[Free Webinar] Community Water Fluoridation: What’s the Evidence?


Recently I’ve come across quite a few Web sites talking about the dangers of adding flouride to community drinking water.
Thought this webinar (which will be archived) might be of interest.


From the Event Information (with a registration link)

Panelist(s) Info:
Maureen Dobbins, Scientific Director, Health Evidence
Duration: 1 hour 30 minutes
Health Evidence will be hosting a 90 minute webinar, funded by the Canadian Institutes of Health Research (KTB-112487), on community water fluoridation, presenting key messages and implications for practice on Tuesday September 11, 2012 at 1:00 pm EST. Maureen Dobbins, Scientific Director of Health Evidence, will be leading the webinar, which will include interactive discussion with Paul Sharma, Manager of the Oral Health Section, Chronic Disease and Injury Prevention Division, Peel Public Health. Paul has also held positions as Manager of the Oral Health programs at Middlesex-London Health Unit and Manager in the Department of Oral Health at the Hastings & Prince Edward Counties Health Unit, and sits on the Executive of Ontario Association of Public Health Dentistry (OAPHD), and the Association of Local Public Health Agencies (alPHa) Board of Directors.

This webinar will review various sources of information with respect to fluoridation, including interpreting the evidence in the following review:

McDonagh, M., Whiting, P., Bradley, M., Cooper, J., Sutton, A., Chestnutt, I., Misson, K., Wilson, P., Treasure, E., Kleijnen, J. (2000). A systematic review of public water fluoridation. York, ON: NHS Centre for Reviews and Dissemination, University of York.

RESULTS: 214 studies were included. The quality of studies was low to moderate. Water fluoridation was associated with an increased proportion of children without caries and a reduction in the number of teeth affected by caries. The range (median) of mean differences in the proportion of children without caries was 5.0% to 64% (14.6%). The range (median) of mean change in decayed, missing, and filled primary/permanent teeth was 0.5 to 4.4 (2.25) teeth. A dose-dependent increase in dental fluorosis was found. At a fluoride level of 1 ppm an estimated 12.5% (95% confidence interval 7.0% to 21.5%) of exposed people would have fluorosis that they would find aesthetically concerning.
CONCLUSIONS: The evidence of a beneficial reduction in caries should be considered together with the increased prevalence of dental fluorosis. There was no clear evidence of other potential adverse effects.]
For those not able to make it at the scheduled date and time, an online posting board will be available following the webinar to view the PowerPoint slides, recording of the presentation, and questions asked and answered during the session.
