Artificial fluoride added to public drinking water for the purpose of reducing cavities is a drug. Adding any drug to water is a direct violation of our citizen’s right of informed consent. No other drug, in Canada or anywhere in the world, is allowed in drinking water. There is significant scientific evidence that, among many other identified poss...

The observed large reduction in dental caries incidence worldwide since the 1970s is shown to correlate with reduction in airborne Lead due to phase-out of Tetraethyl Lead use in gasoline. This accounts also for the fact that there is no discernible difference in dental decay rates between nations that suffer Fluoridation and those where it is bann...

A new intrinsic defect, the mercurous ion (Hg–Hg)<sup>2+</sup>, is proposed to account for n‐type doping of Hg 1-x Cd x Te by excess mercury. The double cations can be formed through capture of neutral interstitial mercury atoms by mercuric ions. This effectively decouples the mercuric ion from the four tellurium atoms previously coordinated, relea...
