Activist confusion at fluoridation bill hearing (and coffee) - Open Parachute

Ken Perrott Mar 24, 2017

I have been in Wellington for the Parliamentary select committee hearings on fluoridation. Well, that was the excuse – I was really there to catch up with my family (always a joy and am amazed at how tall my grandson has become) and to enjoy the great food in Wellington cafes. Havana Coffee Works in Tory Street, Wellington. Great coffee … Read More

Anti-fluoride authors indulge in data manipulation and statistical porkies - Open Parachute

Ken Perrott Mar 12, 2017

Darrell Huff & Irving Geis wrote a classic book – How to Lie With Statistics. They outline various ways data can be presented to give the wrong story. However, there is an even more naive use of statistics to misrepresent data – just declare that a relationship is statistically significant, don’t show any data or statistical analysis. Unfortunately, many … Read More

Aunty Cecily - Kidney Punch

John Pickering Mar 09, 2017

This International Women’s Day I read a re-post of a wonderful article about Otago University women in science.  I thought I’d add another one, my Aunt Cecily, or to the rest of the world Dame Cecily Pickerill. Dame Cecily Pickerill. Aunty Cecily was clever, determined, and, yes, a tough woman.   It was those qualities that helped her … Read More

EPA comprehensively debunks anti-fluoride claims of a fluoride-IQ effect - Unsorted

Ken Perrott Feb 26, 2017

The US environmental Protection Agency (EPA) has denied an anti-fluoride petition to ban community water fluoridation. The document outlining its reasons for declining the petition is valuable because it considers all the arguments and evidence presented in the petition and comprehensively shows them to be misleading or even false. This is a humiliating defeat for the petitioners – the US  Fluoride Action … Read More

Anti-fluoridationists go to Supreme Court – who is paying for this? - Open Parachute

Ken Perrott Feb 22, 2017

The costly battle to prevent fluoridating the water supply of two small Taranaki towns has gone on for four years – and it looks like continuing. Last October the South Taranaki District Council won a costly four-year court battle for the right to fluoridate the water supplies of Patea and Waverley. New Health NZ, which took High Court action to … Read More

Debunking a “classic” fluoride-IQ paper by leading anti-fluoride propagandists - Open Parachute

Ken Perrott Feb 21, 2017

Three of the paper’s authors – Quanyong Xiang (1st Left), Paul Connett (2nd Left) and Bill Hirzy (far right) – preparing to bother the EPA. Anti-fluoride groups and “natural”/alternative health groups and websites are currently promoting a new paper by several leading anti-fluoride propagandists. For two reasons: It’s about fluoride and IQ. The anti-fluoride movement recently decided to give priority to this issue … 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

Big data + Big science = Big health - Kidney Punch

John Pickering Feb 03, 2017

Big data and big science are buzz phrases in health research at the moment.  It is not at all apparent what the exact definition of these are or should be and whether they will be short lived in our lexicon, but I think it reasonable to assume that where there is buzz there is honey. Big Data I think of … Read More

Ken Perrott Jan 31, 2017

New Zealand anti-fluoride campaigners have whittled their list of objections to community water fluoridation (CWF) down to 12 reasons. Maybe that’s progress – they used to tout a list of 50 reasons! Let’s go through that list one by one and see if any stand up. I am responding here to each reason given in the Fluoride Free New Zealand’s … Read More

Adults benefit from community water fluoridation as well as children – new research - Open Parachute

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
