Abstract
Fluoridation cessation: More science from Alberta.
Highlights
Absence of a 2009/2010 Edmonton data point, which, coupled with the wide confidence interval in Calgary, makes it problematic to draw conclusions from that data point
The authors refer to a “control” community, which is erroneous because it implies that fluoridation cessation was a research intervention
If there is an effect of fluoridation cessation on dental caries, it should be stronger in this subsample
Summary
Absence of a 2009/2010 Edmonton data point, which, coupled with the wide confidence interval in Calgary, makes it problematic to draw conclusions from that data point. Considering our whole work,[2,3,4] one will find the data point in question, including our observation in Calgary between 2004/20052009/2010 (precessation) and 2009/2010-2013/2014 (largely postcessation) of a small increase in slope for deft prevalence (%>0; the worsening speeds up) in the latter relative to the former. We reasoned[2] that fluoridation cessation might first affect prevalence rather than means, which are influenced by children with more severe caries.
