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

Anyone interested in my article on this subject in Neurotoxicology and Teratology can now download a pdf version: Perrott, K. W. (2015). Severe dental fluorosis and cognitive deficits. Neurotoxicology and Teratology, 48, 78–79. The publishers tell me that anyone who … Continue reading

Severe dental fluorosis and cognitive deficits – now peer reviewed

Last May I raised the possibility that the much touted relationship of small IQ declines for children living in areas with naturally high fluoride in drinking water could be associated with severe dental fluorosis and not a chemical neurotoxicant (see Confirmation blindness … Continue reading

Water fluoridation and dental fluorosis – debunking some myths

Dental fluorosis is really the only “negative” side effect of community water fluoridation (CWF). It occurs in non-fluoridated as well as fluoridated areas but is often a little more common in the fluoridated areas. However, there is a lot of … Continue reading

Severe dental fluorosis the real cause of IQ deficits?

Ideologically motivated political activists often make extreme claims. Perhaps they feel their claims will never be challenged because they are aimed at their own supporters. Sometimes I think it is because they just don’t get challenged enough by reasonable people. … Continue reading

Endemic fluorosis and its health effects

  The public debate in New Zealand might convince the casual reader that all the science related to fluoride revolves around tooth decay and IQ. But that is certainly not the case on a world scale. The World Health Organisation gives … Continue reading

Facts about fluorosis – not a worry in New Zealand

A recent issue of the Fluoride Exposed Newsletter gives us the facts about dental fluorosis – a subject very often misrepresented by opponents of community water fluoridation. Fluoride Exposed also explores what U.S. Surgeon Generals have done to promote prevention … Continue reading

Premature births a factor in cognitive deficits observed in areas of endemic fluorosis?

Anti-fluoridation activists are soon likely to be promoting a new paper reporting a study which found a relationship between maternal (in utero) exposure to fluoride and cognitive development delay in infants. Of course, they will be unlikely to mention the study … Continue reading
