Cochrane fluoridation review. III: Misleading section on dental fluorosis

The Cochrane review did not look at the effect of community water fluoridation (CWF) on dental fluorosis. It simply reviewed data on the prevalence of dental fluorosis at different fluoride drinking water concentrations – up to 7.6 ppm which is … Continue reading

Big problems with Sitemeter The problems with SiteMeter are even worse this month. No data could be obtained for about 50 blogs using SiteMeter. People have also reported strange results. So if you wish to query the information in the table … Continue reading

I have noticed a few “Letters to the Editor” and social media comments lately misrepresenting the “York review” on fluoridation so looked into the background of some of these claims. The “York review” (McDonagh, et al., 2000) is one of the earliest authoritative and comprehensive reviews of the scientific literature related to fluoridation and resulted from a … … Continue reading
