Islamophobia or mental illness?

Ken Perrott Feb 16, 2017

Mental illness is far more widespread than we often wish to admit. In fact, it is probably worth considering it a normal part of life – like the occasional cold or other ailments we all get. But occasionally mental illness can be more debilitating – even embarrassing. Does any family not have a member who sometimes embarrasses them by behaving inappropriately? … Read More

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

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

January ’17 – NZ blogs sitemeter ranking

Ken Perrott Feb 01, 2017

Here are the rankings of New Zealand blogs with publicly available statistics for January 2017. There are about 300 blogs on the list, although I am weeding out those which are no longer active or have removed public access to sitemeters. (Let me know if I weed out yours by mistake or get your stats wrong). Every month I get queries from … Read More

Debunking anti-fluoridationist’s remaining 12 reasons for opposing fluoridation

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

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

Water fluoridation – what to expect in the near future

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

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

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

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
