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.

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

Water fluoridation – what to expect in the near future - Open Parachute

Ken Perrott Jan 21, 2017

Community water fluoridation (CWF) will persist in science news for the foreseeable future – not for any valid scientific reason but because of reaction to political pressures against it. This is particularly so in New Zealand where our parliament will be discussing legislative changes to fluoridation decision-making this year. This is not to say that all the relevant news will be … Read More

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

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

A new study has found, once again, that community water fluoridation (CWF) saves more than it costs. Carrying on from the previous most comprehensive study in 2001 this new study is based on updated costs of CWF and the averted lifetime costs of dental treatment in the United States. It estimates savings from averted tooth decay in 2013  as a result … Read More
