the subject at hand: is there evidence to support the claim that dental
amalgams are poisoning people, and have been for a century. I suggested
that their is scant evidence to support the claim. I'm not saying that
it isn't a reasonable hypothesis. I am being neither quarrelsome nor
blind, and I certainly don't intend to obfuscate. If it was my use of
literary directives that confuse you, I apologize. Also, I am not trying
to dominate an argument, nor hide the truth, but rather find it.
I checked your reference and indeed there are numerous peer reviewed
works cited. good. I will take them one at a time as to what I can
glean from them. I will focus only on those that relate to toxic effects
of dental amalgam. A bunch of them address the broader issue of Hg in
the environment, or other forms of Hg which as noted have wildly
different toxicities.
"Dental Mercury Impairs Kidney Function"
certainly you want to lead with strong data. This is a good paper, the
data used controls and showed that over the short term- 60 days -that
there were minor changes in kidney function, which could be explained by
the mercury interfering with tubular reabsorption.
However, it was also noted that : "Concentrations of K, urea,
Y-glutamyl transpeptidase, alkaline phosphatase, and total protein did
not change significantly form (sic)0 to 60 days in urine. Plasma levels
of Na, K, urea, and albumin remained unchanged form 0 to 60 days after
amalgam. Renal histology remained normal in amalgam-treated animals. It
is concluded that amalgam Hg levels in kidney are sufficient to
significantly reduce the rate of inulin clearance by non defined
mechanisms and that electrolyte patterns in urine are consistent with
impaired renal tubular reabsorption.
Could one extend this result to humans, and over a much longer period of
time? I bet the Hg release is greatest after initially installing the
amalgam and decreases steadily over time to reach some steady state- is
that release significant? the study has it limits. Another important
factor is sheep chew a heck of a lot more than people. The bruxation
surely causes release of more mercury than would be observed in non-cud
chewers.
Dental Mercury Provokes an Increase in Oral and Intestinal Floras
What this paper says is that low concentrations of Hg result in Hg
resistant bacteria in vivo. No surprise there. The authors then go on
to say the risk is that antibiotic resistant genes may share the same
plasmid as the gene for Hg resistance. Hence stimulation of Hg
resistance may increase the transmission of antibiotic resistance in
various microflora.
It would seem easy enough to examine the microflora of those with and
without dental amalgams, and compare levels of antibiotic resistance.
more later.
