New fluoride debate falters - Open Parachute

Ken Perrott Oct 26, 2017

What is it with these anti-fluoride campaigners – and particularly their leaders? They make a song and dance about having “science on their side.” They will heavily promote the latest research and papers if they can argue that they confirm their bias. And they will email politicians or make submissions to local bodies making scientific claims – often with citations and long lists of references. Read More

Flaw and porkie in anti-fluoride report claiming a flaw in Canadian study - Open Parachute

Ken Perrott Oct 19, 2017

 Anti-fluoride campaigners have launched another attack on a Canadian fluoridation cessation study. They claim it is flawed – but there is a huge flaw in their own critique. Anti-fluoride group, Fluoride Action Network, ironically stamps their own critique of the Calgary fluoridation cessation study as “debunked.” I discussed their original attack in February last year (see Anti-fluoridationist’s flawed attacks on … Read More

Endemic fluorosis and its health effects - Open Parachute

Ken Perrott Sep 28, 2017

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 guidelines for the concentration of fluoride in drinking water recommending it should be in the range 0.5 – 1.5 mg/L. OK, … Read More

Maternal urinary fluoride/IQ study – an update - Open Parachute

Ken Perrott Sep 24, 2017

 The maternal urinary fluoride/IQ study  (Bashash et al., 2017) continues to get attention – but mainly from anti-fluoride organisations. The scientific community will evaluate the published report after giving it due consideration and there have already been criticisms. But anti-fluoride campaigners consider it the best thing since sliced bread. The Fluoride Action Network (FAN) describes it as … Read More

Fluoride, pregnancy and the IQ of offspring - Open Parachute

Ken Perrott Sep 22, 2017

What’s the story about this new IQ-fluoride study? The one that claims fluoride intake by pregnant women could endanger their children’s IQ? Whatever the truth, it has certainly got the anti-fluoride activists going. Mary O’Brien Byrne, leader of the local anti-fluoride group is even suggesting people check if their mothers lived in fluoridated areas. And they are busy promoting the newspaper articles … Read More

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

Are fluoride researchers sacked for their findings? - Open Parachute

Ken Perrott Aug 11, 2017

Heard the one about the scientist who was doing excellent research but was sacked by her Institute because her discoveries shattered the prevailing “scientific orthodoxies?” Yes, it is a common claim. Often made by activists promoting conspiracy theories.  But it is an easy one to make and it is always worth checking the facts in such cases. Of course, the … Read More

Local anti-fluoride activists tell porkies yet again - Open Parachute

Ken Perrott Aug 03, 2017

Well, I suppose that’s not news. A bit surprising, though, because they are claiming the absence of research on fluoridation and IQ – which sort of conflicts with the previous attempts to actually condemn and misrepresent the actual research on fluoridation and IQ. Fluoride Free NZ’s (FFNZ) face book page is claiming: Would you be interested to know that no studies … Read More

ChildSmile – a complement, not an alternative, to fluoridation - Open Parachute

Ken Perrott May 18, 2017

Local antifluoride activists are busy presenting ChildSmile and similar programmes as alternatives to fluoridation. They aren’t – and New Zealand District health Boards already operate elements of these programmes where they consider them effective. I am currently dealing with family issues so am reposting this article, “ChildSmile dental health – its pros and cons” from September 2015.   There is … Read More

Fluoridation helps protect adult teeth as well as children’s - Open Parachute

Ken Perrott May 16, 2017

Recent research reveals that community water fluoridation benefits adults as well as children. While research into the effects of fluoridation in adults started earlier than for children, early studies suffered from a lack of information on effects of socioeconomic status and other confounding factors.  Recent studies with adults have been more robust but there is still some confusion – especially since … Read More
