Anti-fluoridation activists buy scientific credibility using a predatory publisher - Open Parachute

Ken Perrott May 30, 2018

A group of well-known anti-fluoride activists have just published some new research. Well, this is what their social media publicity will tell us. In fact, this is not new research. It is simply the republication of a shonky paper from two years ago as a  chapter in a book produced by a predatory open access publisher. It is a clear example … Read More

Not just another rat study - Open Parachute

Ken Perrott May 09, 2018

A new high-quality study of the effect of fluoride on the memory and learning behaviour of rats has produced definitive results. Anti-fluoride campaigners had great hopes this study would bring an end to community water fluoridation (CWF) – but their hopes have been dashed. The study showed no effect of fluoride on the memory, learning and motor skills of rats thus reinforcing the consensus … Read More

Paul Connett “updates” NZ MPs about fluoride - Open Parachute

Ken Perrott Feb 22, 2018

 Data from Bashash et al., (2017). Despite a statistically significant relationship of child IQ with mothers prenatal urinary fluoride, this explains only about 3% of the huge scatter in the data.

What’s with the anti-fluoridationist promotion of dental health programmes? - Open Parachute

Ken Perrott Sep 11, 2017

Anti-fluoride campaigners often promote dental health programmes which they argue are alternatives to community water fluoridation. But seem not to understand that these programmes usually include fluoride dental treatments. It’s probably a result of some tactical thinking – “let’s promote a positive message to overcome the publicly perceived negativity associated with our opposition to a social health policy like fluoridation.” In fact, some New Zealand … Read More

Non-fluoridated Christchurch does not have better teeth than fluoridated Auckland - Open Parachute

Ken Perrott Feb 07, 2017

It seems every time anti-fluoride propagandists present data it is either cherry-picked, distorted or misleading. Often all three. So it is hardly a surprise to find local anti-fluoride propagandists are telling porkies again. They have been promoting this graphic claiming it shows people in “non-fluoridated Christchurch have “better teeth.” But the graphic is based on naive cherry-picking of the data, it ignores the effect different ethnic … Read More

Ken Perrott Jan 24, 2017

A new Australian study confirms that lifetime access to community water fluoridation (CWF) is associated with reduced tooth decay for adults – at least in the age groups 15 – 34 years and 35 – 44 years. The study is reported in the paper: Do et al., (2017). Effectiveness of water fluoridation in the prevention of dental caries across … Read More

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

Ken Perrott Jan 20, 2017

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. Could the increased incidence of premature births explain cognitive deficits observed in areas of endemic fluorosis? Image credit: New Kids-Center. Of course, they will be unlikely … Read More

More nails in the anti-fluoridation myths around IQ and hypothyroidism - Open Parachute

Ken Perrott Jan 16, 2017

A new Canadian study shows no relationship of cognitive deficits or diagnosis of hypothyroidism with fluoride in drinking water. This work is important because it counters the claims made by anti-fluoride campaigners. While the campaigners cite scientific studies to support their claims, those studies are usually very weak, or irrelevant because they involve areas of endemic fluorosis where drinking … Read More
