Ken Perrott Apr 04, 2018

Slide number 30 from Paul Connett presentation prepared for a talk at NZ Parliament buildings in February 2018. Continuing my critique of the presentation prepared by Paul Connett for his much-publicised meeting at Parliament Building in February.

Paul Connett’s misrepresentation of maternal F exposure study debunked - Open Parachute

Ken Perrott Mar 06, 2018

Anti-fluoride campaigners are misrepresenting a recent Mexican study claiming its findings should cause governments around the world to abandon community water fluoridation (CWF). Their claims are unwarranted because the study has a high degree of uncertainty. Activists are misrepresenting the accuracy of the studies findings. Because Mexico has areas of endemic fluorosis the study itself is not relevant to CWF. Read More

Opinion: Anti-fluoride activist commits “Death by PowerPoint” - Open Parachute

Ken Perrott Feb 28, 2018
