With 1.6 billion amalgams out there, that's a pretty good safety record.

Mercury amalgams were never safe. Not one single study proving the safety.

It would be hard to prove the safety of something which doesn't exist,
but for the purpose of the exercise let's assume that Jan meant
"dental amalgams". As she well knows, because she has been told, there
were studies published earlier this year which failed to demonstrate
any harmful effect of dental amalgam.

Neuropsychological and Renal Effects of Dental Amalgam in Children

Conclusions
In this study, there were no statistically significant differences in
adverse neuropsychological or renal effects observed over the 5-year
period in children whose caries were restored using dental amalgam or
composite materials. Although it is possible that very small IQ
effects cannot be ruled out, these findings suggest that the health
effects of amalgam restorations in children need not be the basis of
treatment decisions when choosing restorative dental materials.

Neurobehavioral Effects of Dental Amalgam in Children

Conclusions
In this study, children who received dental restorative treatment with
amalgam did not, on average, have statistically significant
differences in neurobehavioral assessments or in nerve conduction
velocity when compared with children who received resin composite
materials without amalgam. These findings, combined with the trend of
higher treatment need later among those receiving composite, suggest
that amalgam should remain a viable dental restorative option for
children.

(Only abstracts of these papers are available at present, but as the
papers appeared in JAMA in April the full text might be available next
month.)

So, Jan, you can now stop saying that there have been no studies. You
mightn't like the studies, but you can't deny their existence. To do
so would be lying.

Of course, to thinking people, the sheer number of amalgam fillings
which have been administered over almost two centuries (billions of
fillings in hundreds of millions of mouths) would be reasonable
evidence of safety, as numbers like that would have produced a
noticeable number of clinical cases if there really was anything to
worry about.
