Autoimmune
Disorders
The
diagnostic arena now occupied by autoimmune disorders provides us
with terms that could best be described as "alphabet soup".
Such problems include RA (rheumatoid arthritis), HT (Hashimoto's
thyroiditis), HAD (human adjuvant disease), ALS (amyotrophic lateral
sclerosis or more commonly, Lou Gehrig's disease) and MCTD (mixed
connective tissue disease).
Should
we now add MT (mercury toxicity)?
These
conditions plus others, such as Crohn's disease, Raynaud's disease,
systemic candidiasis, diabetes, and even Alzheimer's disease are
now believed by many to be autoimmune disorders.
When
patients are afflicted with such disorders, they come into their
physician's office with all, or some, of these symptoms:
Generalized
morning stiffness
Skin rashes
Dry eyes and mouth
Joint pain
Immune dysfunction
Axillary lymph node swelling
Subcutaneous nodules (skin bumps)
Neurological symptoms (ringing in ears, burning and numbness sensations)
Chronic fatigue
Depression and/or environmental sensitivities
The clinical assessment usually shows a connective tissue disorder,
the result of the immune system attacking the tissues of the body.
The immune elements of T-lymphocytes, B-cells and "PAC-man"
Cells,
instead of attacking bacterial, viral and yeast fungal invaders,
attack the cells of the thyroid (HT), joint surfaces (RA), peripheral
vascular bed (Raynaud's) or the skin cells with patches across the
nose and cheeks (lupus erythematosus).
There
are no simple answers for this perplexing group of problems, yet
insights are beginning to arrive on the clinical horizon that may
indicate why T-cell mediated lesions are developed and a screening
questionnaire has been developed to help assess this problem (see
Mercury/Toxic Metal Sensitivity Questionnaire). Patients who score
more than five "yeses" should be referred to a dentist
familiar with "silver" amalgam removal.
Any
filling in the mouth that looked silver when it was new and is gray
of black now is probably 50% mercury, the rest being copper, silver,
tin, and zinc. There are numerous amalgam mixes on the market. They
have names like Dispersalloy, Spheraloy, Sybralloy, and Tytin. The
mercury content ranges from 43 to 54%. Although these fillings are
commonly called silver fillings because they look silver for the
first few days of the eight to twelve years they survive in the
average human head, mercury fillings would be a more accurate label
(And speaking of accurate labels, the origins of the word mercury
are both interesting and provocative. Mercury was the God of Commerce
in the Roman Empire and meant fabrication, trickery, thieving and
slight-of-hand.).
In
this article the more formal term "amalgam" is used. The
name "amalgam" reflects the ability of mercury to bind
or amalgamate powdered silver and other metals into a hard filling
Evidence
that these fillings give systemic pathology as well as periodontal
disease exists. In one study it was observed that when 50 subjects
without amalgams were compared to 51 subjects with amalgams, there
was greater incidence of problems in the latter group. They experienced
greater incidence of chest pains, tachycardia, anemia, fatigue and
tendency to tire easily. They also had significantly higher blood
pressure, lower heart rate and lower hemoglobin.
A study
in Canada has shown that pregnant sheep with new silver amalgams
have elevated levels of mercury in their fetuses within two weeks
of placement of the fillings. Further studies on monkeys showed
the same findings. These studies were done by Vimy Takahasi and
Lorscheider at the University of Calgary, Faculty of Medicine.
In
addition to the reports from the United States, Canada and Japan,
European researchers have observed many adverse reports concerning
amalgams. On February 18, 1994, mercury fillings were banned in
Sweden for children and youth 19 years of age because evidence showed
them to be a trigger of autoimmune disorder.
Although mercury fillings have been widely used in the decades since,
research demonstrating that such fillings are safe has yet to be
done. Research that has been done and reported in scientific literature
demonstrates that:
Mercury escapes from fillings in the fillings in the form of vapor
created by chewing. It then enters the bloodstream and is delivered
to all parts of the body, including the brain. (A recent autopsy
of an 82-year old woman from St. Paul with confirmed Alzheimer's
disease had studies done by the Mayo Heavy Metals Lab. Brain tissue
examination showed 5.3 UGIG mercury (53 times the normal levels).
The pathologist reported "neurofibrillary tangle" in the
brain sections that are common in such patients. She had multiple
amalgams.)

People with mercury fillings have higher levels of mercury in their
urine, blood and brain than people without fillings.
Another
significant European development about mercury amalgams was reported
when Degussa AG, the largest producer of dental amalgams in Germany
announced it would no longer provide such amalgams because of pending
and future lawsuits. This was based on a federal Court ruling that
dentists who use such amalgams face legal liability.
Next
come a series of studies by Dr. Catherine Kousmine of France, who
reported that illnesses like MS and chronic polyarthritis, both
autoimmune disease, are triggered by silver amalgams. This is outlined
in her book, La Sclerosa and Plaques Est Guerissable (Multiple Sclerosis
is Curable).
One
more European study on MS comes from Great Britain. It reports that
the highest incidence of MS is found in Northern Ireland and the
Scottish Island of Orkney and Shetland. They also have the highest
incidence of dental cavities and dental fillings. This provides
more suspicion that mercury is a possible link to autoimmune dysfunction.
History
of the Debate about Mercury
French
dentists were the first to mix mercury with various other metals
and plug the mixture into cavities in teeth. The first mixtures,
developed in the early 1800
.
. 's, had relatively little mercury in
them and had to be heated to get the metals to bind. In 1819, a
man named Bell in England developed an amalgam mix with much more
mercury in it that bound the metals at room temperature. Taveau
in France developed a similar mixture in 1826.
When
amalgams were introduced to the US in 1833 by two French entrepreneurs,
the Crawcour brothers, amalgam use was denounced by a substantial
number of American dentists. So strong was the opposition to amalgams
that the American Society of Dental Surgeons, formed in 1840, required
its members to sign pledges promising not to use them. It is an
intriguing historical note that the common term for mercury in Germany
in those years was "quick silver". The German pronunciation
for "quick" is "quack". Thus, those dentists
who used mercury were called "quacks". This term has now
come to mean anyone who is an "ignorant pretender to medical
skill" (The Random House dictionary of The English Language).
In 1848, the Society found 11 of its New York members guilty of
"malpractice for using amalgam" and suspended them. Internal
debate over this issue led to the demise of the Society in 1856.
Its successor organization, the American Dental Association, sought
to unite dentists and, in its early days, did not take a stand on
the issue of amalgam safety. The Encyclopedia Britannica reports
that "amalgams were not altogether in good repute until after
1895", which suggests that the ADA was supporting the use of
amalgams by then. Despite the efforts of a few researchers in this
country and Europe to call attention to the dangers of mercury fillings,
most notably a German chemist named Dr. Alfred Stock who published
numerous articles prior to World War II, and Hal Huggins, a Colorado
dentist who has spoken out against amalgams for the last 20 years,
debate about the safety of mercury fillings remained muffled until
recently.
The
amalgam safety debate was revived in this country first by a 1989
Environmental Protection Agency declaration that amalgams are a
hazardous substance under the Superfund law, and then a December
1990 broadcast of a program by "60 Minutes" that presented
a devastation critique of amalgams. The program created a stir throughout
the country. "Switchboards lit up at the state dental societies,
dental schools, and the American Dental Association," said
Consumer Reports. The American Dental Association got calls from
two dozen reporters. The publicity was the apparent cause of the
following activity in 1991: an FDA hearing; a conference sponsored
by the National Institute of Dental Research; and a call for a review
of the research by the US Public Health Service.
The
dental establishment was furious with CBS. In the January 7,1991
edition of its newspaper for "the irresponsible ways in which
viewers were led to the conclusion that amalgam fillings are unsafe".
To the contrary, said the ADA, "scientific evidence
suggests
mercury amalgam is safe to use". The ADA newspaper published
statements by Dr. Harold Loe, director of National Institute of
Dental Research, criticizing CBS for having "an obvious bias"
against amalgams. Dentists all over the country received information
packets from the ADA, including copies of the ADA newspaper and
a 1986 article from Consumer Reports. The ADA also promoted its
message in a two-minute video news release sent to 700 TV stations
on December 17, 1990, on its weekly radio show on December 18, 1990,
and in its journal, the Journal of the American Dental Association.
The
1986 article by Consumer Reports pooh-poohed those who criticize
the use of mercury in filings. The article concluded: "Dentists
who purport to treat health problems by ripping out fillings are
putting their own economic welfare ahead of their patients' welfare
Except for a few people with a genuine allergy to mercury we know
of no one who's been harmed by them." Consumer Reports published
a similar article in May of 1991 which the ADA and the MN Dental
Association have also distributed widely. This article criticized
research showing that silver-mercury fillings are unsafe and concluded
that "amalgam fillings are still your best bet."
"60
Minutes" and the anti-amalgam movement have other critics besides
the ADA and Consumer Reports - they include the Arthritis Foundation,
the Multiple Sclerosis Society, and the ultra-right Accuracy in
Media - but no one has more credibility on this issue than the ADA
and Consumer Reports. For that reason, it is important for any one
trying to understand this issue to understand the arguments of these
two organizations and why their arguments fail. The positions of
the ADA and Consumer Reports are strikingly similar. They cite the
same sources to reach the same conclusion - that critics have not
shown conclusively that mercury amalgams are unsafe.
