harmful effects:
This must have been posted by Mark Thorson. He has posted it before and it has been discussed. The
part Mark overlooks is this:
The other problem is they talked me into having all 4 quadrants of my teeth done the same week - in
4 consecutive days. Thiswas probably the biggest mistake we made.
Furthermore ther reason Mark repeatedly post this is because he had to make a retraction for saying
things and lying about cell tech.. I called his hand. He is also a lackey for Barrett.

Mercury in dental restoration: is there a risk of nephrotoxicity?
Mortada WL, Sobh MA, El-Defrawy MM, Farahat SE.

BACKGROUND: Concern has been voiced about exposure to mercury (Hg) from dental amalgam fillings,
and there is a need to assess whether this leads to signs of nephrotoxicity. METHODS: A total of
101 healthy adults (80 males and 21 females) were included in this study. The population as grouped
into those having amalgam fillings (39 males and 10 females) and those without (41 males and 11
females). Hg was determined in blood, urine, hair and nails to assess exposure. Urinary excretion
of beta2-microglobulin (beta2M), N-acetyl-beta-D-glucosaminidase (NAG), gamma-glutamyltransferase
(gammaGT) and alkaline phosphatase (ALP) were determined as markers of tubular damage. Albuminuria
was assayed as an early indicator of glomerular dysfunction. Serum creatinine, beta2M and blood
urea nitrogen (BUN) were determined to assess glomerular filtration. RESULTS: Hg levels in blood
and urine were significantly higher in persons with dental amalgam than those without; in the
dental amalgam group, blood and urine levels of Hg significantly correlated with the number of
amalgams. Urinary excretion of NAG, gammaGT and albumin was significantly higher in persons with
dental amalgam than those without. In the amalgam group, urinary excretion of NAG and albumin
significantly correlated with the number of fillings. Albuminuria significantly correlated with
blood and urine Hg. CONCLUSION: From the nephrotoxicity point of view, dental amalgam is an
unsuitable filling material, as it may give rise to Hg toxicity. Hg levels in blood and urine are
good markers of such toxicity. In these exposure conditions, renal damage is possible and may be
assessed by urinary excretions of albumin, NAG, and gamma-GT.

from amalgam fillings into the oral cavity].[Article in Russian]Motorkina AV, Barer GM,

Seventy-five subjects aged 20 to 57 with 1 to 15 fillings of silver amalgam were examined. The level
of mercury vapors in the oral cavity was assessedusing an AGP-01 device and the method developed by
the authors. Emission of mercury vapors in the oral cavity increased with the number of fillings.
The concentration of mercury in the oral cavity depends largely on the number ofsilver amalgam
fillings and less so on these fillings' length of service.Adv Dent Res 1992 Sep;6:110-3

amalgam.Reinhardt JW.Department of Operative Dentistry, University of Iowa College of Dentistry,Iowa

The purpose of this paper is to examine and report on studies that relate mercury levels in human
tissues to the presence of dental amalgams, giving special attention to autopsy studies. Until
recently, there have been few published studies examining the relationship between dental amalgams
and tissue mercury levels. Improved and highly sensitive tissue analysis techniques have made it
possible to measure elements in the concentration range of parts per billion. The fact that mercury
can be absorbed and reach toxic levels in humantissues makes any and all exposure to that element of
scientific interest.
Dental amalgams have long been believed to be of little significance as contributors to the overall
body burden of mercury, because the elemental form of mercury is rapidly consumed in the setting
reaction of the restoration.Studies showing measurable elemental mercury vapor release from dental
amalgams have raised renewed concern about amalgam safety.
Mercury vapor absorption occurs through the lungs, with about 80% of the inhaled vapor being
absorbed by the lungs and rapidly entering the bloodstream. Following distribution by blood
circulation, mercury can enter and remain in certain tissues for longer periods of time, since the
half-life of excretion is prolonged. Two of the primary arget organs of concern are the central
nervous system and kidneys.

Whole-body imaging of the distribution of mercury released from dental fillings into monkey
tissues.Hahn LJ, Kloiber R, Leininger RW, Vimy MJ, Lorscheider FL.Department of Radiology,
University of Calgary, Faculty of Medicine, Alberta,Canada.
The fate of mercury (Hg) released from dental "silver" amalgam tooth fillings into human mouth
air is uncertain. A previous report about sheep revealed uptake routes and distribution of
amalgam Hg among body tissues. The present investigation demonstrates the bodily distribution of
amalgam Hg in a monkey whose dentition, diet, feeding regimen, and chewing pattern closely
resemble those of humans.
When amalgam fillings, which normally contain 50% Hg, are made with a tracer of radioactive 203Hg
and then placed into monkey teeth, the isotope appears in high concentration in various organs and
tissues within 4wk. Whole-body images of the monkey revealed that the highest levels of Hg werel
ocated in the kidney, gastrointestinal tract, and jaw.

Mercury toxicity and dental amalgam.Wolff M, Osborne JW, Hanson AL.There is adequate evidence that
dental amalgam restorations, during and after placement, results in the release of Hg into the
patient's body. Whether the Hg released from amalgam is due to placement procedures, surface
abrasion, orl ater corrosion breakdown, there is evidence that a low level Hg release continues
for years.
****It is generally agreed that if amalgam was introduced today as a restorative material, they
would never pass F.D.A. approval.****
With new and more accurate techniques of measuring Hg levels, especially in tissue and blood,
additional studies are necessary to relate blood-Hg levels with dental amalgam restorations. Studies
must relate existing restorations as well as the placement of new restorations to body-Hg levels.
It is possible that we have accepted a potentially dangerous material as being safe.
