One thing that my posts to sci.med.dentistry have achieved over the
years is that the regular contributors to this newsgroup no longer
bother to assert that dissimilar metals in contact with each other
need an electrolyte to be present in order for them to generate an
electric current.

For the benefit of any newcomers who might still believe in this
falsehood, an elementary description of the thermoelectric effect can
be found at:

http://book.boot.users.btopenworld.com/thermo2.htm

The general principle is that when dissimilar metals are placed in
contact with each other and the points of contact are at different
temperatures an electrical current flows, and the current continues to
flow for as long as the temperature difference is maintained.
(Remember that a typical dental amalgam is an inhomogeneous mixture of
dissimilar metals in its own right - and that it has been common
practice for dentists to screw metal alloy retaining pins into the
root sockets of patients' teeth and encase the heads of the pins in
amalgam.)

The important thing to remember is that this effect occurs without any
electrolysis taking place. There is no "electrochemistry" occurring at
all. There isn't any requirement for an "electrolyte" to be present.
It is entirely a thermoelectric effect.

Anyway, the latest news is that Professor L I Anatychuk of the
Institute of Thermoelectricity in the Ukraine, one of the world's
greatest living authorities on thermoelectric phenomena, believes that
the thermoelectric behavior of a piece of metal is enough on its own
to stimulate neurological synapses in animal tissue. (See: "Seebeck or
Volta?", L.I.Anatychuk, Journal of Thermoelectricity, No.1, 1994)

However, in spite of this it appears that there isn't anyone anywhwre
in the world who knows what the thermoelectric properties of metal
dental restorations are.

Attached below is a series of entreaties which have been submitted to
the website of the International Thermoelctric Society on this topic -
so far without any comment or contestation in return.

I thought that newsgroup members might be interested to read them.

Academician, Professor L. Anatychuk from Ukraine, scientist, engineer,
the author of books and scientific works, editor of "Journal of
Thermoelectricity", organizer and President of the International
Thermoelectric Academy is well known to thermoelectric community.

On July 15 Dr. Anatychuk celebrates his 70-th jubilee and 50-th
anniversary of scientific and pedagogical activity in the field of
thermoelectricity.

On the eve of this glorious jubilee, President of Ukraine Viktor
Yuschenko awarded Dr. L.Anatychuk with the Order "For Meritorious
Service" of first degree. A Decree on this deed of esteem has been
officially
announced on the site of President of Ukraine http://www.president.gov.ua

Dr. L.I. Anatychuk had been already awarded with 4 Orders, among them
2 Orders "For Meritorious Service" of second and third degree. Now by
the Decree of President Yuschenko the two Orders "For Meritorious
Service" have been supplemented by the Order "For Meritorious Service"
of first degree. Thus, Dr. Anatychuk becomes full holder of three
Orders "For Meritorious Service". In the Decree it is noted that
these awards are for the "achievements in science, technology and
education".

Congratulations to Dr. L.I.Anatychuk! Well done!

Submitted by kpw on Tue, 2007-09-11 12:26.
A few years ago the organisation "Health Canada" issued the following
statement via the website of the Canadian Dental Association regarding
the placement of metal amalgam dental fillings:

"It should be noted that Health Canada has taken the position that new
amalgam fillings should not be placed in contact with existing metal
devices in the mouth"

I wrote to the Canadian Dental Association regarding this statement
with the following query:

"Is this recommendation intended to apply to metal alloy retaining
pins screwed into the root sockets of a patient's tooth?"

And I received the following reply from Dr Philip Neufeld of Health
Canada:

"Dear Mr. Walsh:

Health Canada's position statement on amalgam recommended against
placing amalgam fillings in patients who have existing metal devices
because this results in having dissimilar metals in the mouth.
Dissimilar metals set up galvanic currents which can cause two
problems. First, they accelerate the corrosion of the amalgam. This
leads to pitting, crevice formation, and marginal leaks, shortening
the life of the filling. The corrosion also increases the rate of
mercury vapour release.

Second, galvanic currents can cause a tingling sensation or a metallic
taste in the mouth which are annoying to the patient. Sometimes the
currents can cause inflammation or sores on the gums, tongue or the
inside of the cheek in contact with the metals.

However, it is unlikely that a metal retaining pin implanted into the
tooth or the jaw bone would cause galvanic currents. In order for
galvanic currents to be created, the pin would have to be in contact
with an electrolyte such as saliva or extracellular fluids, and such
retaining pins are usually not exposed. Health Canada recognizes that
although it is preferable to avoid dissimilar metals in the mouth,
there may be situations where there is no practical alternative.
Dental practitioners are therefore expected to take these factors into
consideration in making decisions on treatment.

Yours sincerely,

Philip Neufeld, Ph.D."

This left me with the distinct impression that Dr Neufeld was being
completely negligent of any possible thermoelectric effects.

Not only is dental amalgam an inhomogeneous mixture of dissimilar
metals in its own right, but our knowledge of thermoelectric effects
tells us that, in addition to any thermoelectric activity which might
arise from temperature gradients in the amalgam itself, any
arrangement whereby an amalgam filling is placed in contact with a
metal retaining pin screwed into a patient's tooth might also be
reasonably expected to provide further potential for the generation of
thermoelectric emf and eddy currents along the contours of the
interface between the amalgam and the retaining pin.

But as we have seen, it appears that dentists in Canada are totally
ignorant of any thermoelectric behavior that such dental restorations
may produce.

Are dentists in other countries any less ignorant?

Well maybe not.

Self-styled "dentist to the stars" Philip Wander of Manchester in
England, who specialises in the removal of amalgams, at least warns of
the problems which can arise as a result of the electrical potentials
generated by amalgam dental restorations:

"Nevertheless, as potentially damaging as mercury in the mouth is the

Quote:

electricity itself. When testing teeth for electrical effects, I
have seen momentary sparks of up to one volt - enough to light a small

torch or flashlight. It's worth remembering that the currents
generated by amalgams are formed very close to the brain, which
ordinarily operated at far lower potentials (only a few millivolts).
The brain lies only a few millietres from the jaw bone, where the
roots of the teeth are inserted, just on the other side of the thin
cranial bone and the meninges (the three membranes enveloping the
brain and spinal cord). This kind of current can cause mental
dysfunction, which I often find in clinical practice."

See:

http://www.wanderdental.co.uk/mercuryfreedentistry.html

However I suspect that even he wouldn't know the extent to which the
voltages he talks about are generated by thermoelectric phenomena.

Interestingly though, one of Dr Wander's celebrity patients appears to
have been Ukrainian soccer star Andrei Kanchelskis. More amazingly, if
you search Dr Wander's website you will discover that Kanchelskis even
brought his own mother-in-law over to England from the Ukraine to have
her teeth sorted out too.

It appears that dentists in the Ukraine may be just as ignorant as
those in Canada.

What's the point of a country having the world's greatest authority on
the science of thermoelectricity if the dentists in that country are
still totally clueless as to the thermoelectric behavior of the
inhomogeneous mixtures of dissimilar metals that they place in their
patients' mouths?

I'd say that if Professor Anatychuk could redress this ignorance then
perhaps he really would deserve a medal!

Thermoelectricians,

It appears that there isn't anyone anywhere in the world who knows
what the thermoelectric properties of a typical dental amalgam are.

And amalagam fillings are placed in children's teeth.

It's idiotic.

If it turned out that the thermoelectric potentials generated by
amalgam dental fillings are large enough to dissipate electrical
energy through the nerves in people's heads, then the reputation of
every thermoelectrician in the world, including that of Professor L.
I. Anatychuk, would not be worth a fig.

Perhaps this explains why it appears that there isn't anyone anywhere

Old Professor Anatychuk
Submitted by kpw on Thu, 2007-11-22 09:27.
Old Professor Anatychuk appears to believe that the thermoelectric
behavior of a piece of metal is able to stimulate neurological
synapses in animal tissue (see "Seebeck or Volta?", L.I.Anatychuk.,
Journal of Thermoelectricity, No.1, 1994)

Of course, there are no muscles which might be caused to jump in the
upper and lower mandibles of the human head. However there are
sensitive organs nearby.

It makes me wonder whether people with metal fillings in their teeth
ever complain of ringing in their ears?

And if they do, do any of them refuse to believe that their condition
was caused by listening to loud rock music?

Well, it appears that the painter Vincent van Gogh complained quite
desperately of ringing in his ears. Of course, no-one told him he was
suffering from "tinnitus", because they hadn't thought of a name for
this condition back then. They just told him he was crazy.

One thing's for certain, Vincent van Gogh never attended a Led
Zeppelin show. Although apparently he did have rather bad teeth.

You know, the widespread adoption of metal amalgams for use in
restorative dentistry was quickly followed by the rise to promonence
of psychiatric "medicine" in our societies. And presumed
"explanations" such as "manic depression" or "schizophrenia" are not
explanations at all. Like "tinnitus", they are simply terms which have
been used to describe particular groups of symptoms.

So come on thermoelectricians. Measure the thermoelectric behavior of
metal amalgam dental fillings. You never know, members of the dental
profession might be most grateful (but I suspect only if you can tell
them what they would wish to hear - otherwise they might prefer that
you keep it to yourselves).

And you might even be confirming the great Professor Anatychuk's
theories.

Keith P Walsh

PS, a typical dental amalgam is an inhomogeneous mixture of dissimilar
metals in its own right (see: http://book.boot.users.btopenworld.com/setting.htm)

Not only that, but it has been common practice for dentists to screw
metal alloy retaining pins into the root sockets of their patients'
teeth and encase the heads of the pins in metal amalgams.

However, in spite of these facts it appears that there isn't anyone

One last thing.

If you go to:

http://book.boot.users.btopenworld.com/intro.htm

- you will find a series of letters asking questions about the
electrical behavior of metal dental restorations in which the writer
clearly recognises the link between the thermoelectric effect and
Alessandro Volta's frog's leg experiment. (It was actually Luigi
Galvani who demonstrated the frog's leg effect first, but he made the
unforgiveable mistake of suggesting a wrong explanation for it, so his
contribution is often dismissed - in much the same way that Thomas
Johann Seebeck's contribution in stumbling across the Seebeck effect
is also dismissed by some people.)

These letters were all written in 1992, more than a year before the
publication of Professor Anatychuk's paper, "Seebeck or Volta?", in
the Journal of Thermoelectricity.

Of course, I'm not suggesting that the Ukrainian government is giving
its award to the wrong person.

But I wonder who wrote those letters?

Any guesses?

There could be (and usually is) a temperature gradient
across a dental filling -- or pretty much anything else.
Only a few things like the contents of a Thermos bottle
that hasn't been opened recently would be at a uniform
temperature.

That said, Walsh is clearly delusional with regard
to his dental amalgam theory. His theory could be
adequately tested by simple experiments, yet he seems
to have no interest in performing these experiments,
even though he has been offered assistance in
designing these experiments by experts in sci
newsgroups. No, he'd just prefer to beat his
well-worn drum.

Greggie,

Thank you for your question.

In Nature temperature difference is ubiquitous.

A good example of how a temperature difference can occur across a
metal dental filling is when someone bites into ice-cream.

Human body temperature is 37 degrees celsius, and ice-cream is usually
at a temperature of around 0 degrees celsius when it is eaten. So in
this circumstance a temperature difference of around 37 degrees
celsius will immediately occur across the filling.

If you go to:

http://www.elektrotechnik.hs-magdeburg.de/Mitarbeiter/hinken/news/N6.htm

- you will see a graphical representation of the thermoelectric eddy
current and associated electromagnetic field which are generated
whenever an element of one electrical conductor is completely encased
within another and subjected to a thermal gradient (figure d is
particularly instructive).

Now, a typical dental amalgam may be accurately described as an
inhomogeneous mixture of dissimilar metals in which a great many
elements of one electrically conductive material are all completely
enclosed within a matrix of another, dissimilar, electrically
conductive material. See:

http://book.boot.users.btopenworld.com/setting.htm

So, according to the scientific principle established above, when a
temperature difference is established across an amalgam dental filling
then thermoelectric eddy currents MUST flow around the "unreacted"
alloy inclusions in the amalgam.

As far as I know, experiments to determine whether or not the
associated electromagnetic fields can be detected outside the surface
of the fillings have not been carried out. (And if Mark Thorson tells
you he has offered to buy me the equipment necessary to do this myself
don't believe him - he hasn't.)

Do you think it's possible that these electromagnetic fields are in
fact detected by the nerves in peoples' heads?

And have you ever heard of an "ice-cream headache"? I have, and I
didn't make it up myself.

thermoelectric eddy currents will be zero.

As far as I know, experiments to determine whether or not
the associated electromagnetic fields can be detected
outside the surface of the fillings have not been carried
out. (And if Mark Thorson tells you he has offered to buy
me the equipment necessary to do this myself don't believe
him - he hasn't.)

Well of course you should do the experiments or pay to have
them done, but I don't see how this inhomogenous mixture can
create anything but a zero eddy current.

I don't think it's likely that these electromagnetic fields
are in fact detected by nerves.

But here's one for you. Scientists are rebuilding coral reefs
by the application of continuos low voltage to the reefs.
Seems to me you have an analagous situation here and that if
indeed the amalgam was generating any current at all, it
would be helping to rebuild the tooth.

In addition, the long term application of a low voltage eddy
current would have the net effect of deteriorating the
filling and depositing material in the tooth cavity. Are
there any published reports of fillings that are removed
having any pitting action, or the cavities being coated with
some metallic residue?

And have you ever heard of an "ice-cream headache"? I have,
and I didn't make it up myself.

Yes I have and it has nothing to do with eddy currents, but
if you get one, stick your thumb in the middle of your
forehead and push hard. This works.

Electrical current with the power to destroy
Two dissimilar metals in a saliva environment will produce electrical
current by galvanic action, and become a battery of sorts. The five metals
frequently found in most amalgam formulations produce an even more complex
battery. The electrical currents produced by amalgam are far greater in
magnitude than the sensitive electrical currents the brain operates on, and
are far greater than the current that activates acupuncture meridians.

These abnormal electrical currents can cause or contribute to a wide variety
of symptoms and disease. Amalgam removal in patients who have conditions
related to galvanic electrical generation sometimes produces almost
immediate improvements.

Electrical potentials of restorations in subjects without oral complaints.

Muller AW, Van Loon LA, Davidson CL.

Department of Dental Materials Science, Faculty of Dentistry, University of
Amsterdam, The Netherlands.

The electrical potentials of 183 amalgam and 11 precious metal restorations,
and one set of brackets, were measured. None of the 28 subjects had
galvanism,
leukoplakia, oral lichen planus, or toxic or allergic reactions to
restorations. The potentials of the amalgam restorations increased with age,
from about -350 mV NHE at 30 days, to about +100 mV NHE after more than 1000
days. In most subjects potential differences of more than 50 mV were present
between restorations; this phenomenon is therefore assumed to be common in
healthy populations.

Finally there are the galvanic currents. Galvanic currents are electrical
charges originating in the metal fillings - heavy metal (mercury) and salt
water (saliva)
equals a battery, so that each amalgam filled tooth produces a small current
of
electricity. This current can be measured in millivolts or microamperes.
Several fillings mean that the mouth becomes 'live' with electrical
voltages.
These voltages establish circuits which are constant and a person lives with
them and does not notice them - except! - chew some silver paper and see
what
happens! The silver paper disrupts the established circuits and new circuits
are rapidly formed, broken and reformed and discomfort is experienced. The
pain
from biting on a filling with silver paper is an electric shock.

Many people experience static electricity problems and it is commonly
assumed
that the current jumps from the car/filing cabinet/etc to the person but it
actually happens the other way around - the teeth batteries produce the
current
which builds in the body and goes to ground on contact with a good
conductor,
jolting the body. In my experience everyone who suffers with problems with
static electricity finds that after the amalgams are removed this problem
goes
away completely. So, what's a little static jolt now and again, other than a
little nuisance?

Consider : the body is 70% water which is a good conductor of electricity,
this
means that the electrical disturbance originating in the mouth is dispersed
throughout the entire body.

Consider : the central and peripheral nervous systems function on
electricity,
even cellular metabolism functions on electricity - this means that all
central
and peripheral nervous system activity and cellular metabolism will be
affected
by the batteries and electric currents in your mouth. Science to date has
not
investigated this area very much, but there are notions that if the current
is
over 3 microamperes or 100 millivolts, then treatment is recommended. My

So, according to the scientific principle established
above, when a temperature difference is established across
an amalgam dental filling then thermoelectric eddy currents
MUST flow around the "unreacted" alloy inclusions in the
amalgam.

But as there are so many places where the temperature
difference can happen and there is an equal chance that half
of the bits causing eddy currents will have opposite charges,
there is an equal and likely chance that the net
thermoelectric eddy currents will be zero.

Zero eh?

Can you think of an experimental procedure which might be carried out
in order to confirm this?

The principle of thermoelectric eddy current is used to identify
inclusions of dissimilar metals in metal objects.

The object is subjected to a temperature difference and the
electromagnetic fields generated by any thermoelectric eddy currents
arising within the material are detected by sensitive measuring
instruments placed at the surface.

I'd say that if a piece of dental amalgam was subjected to a thermal
gradient, and the most sensitive instrument available was unable to
detect any electromagnetic effect at the surface of the amalgam, then
this would tend to suggest that you are right.

Wouldn't you agree?

However there are

Mainly your brain-stem.

Somethings that can be caused by your brain-stem not working properly

Diseases of the brain-stem can result to abnormalities in the function
of cranial nerves, which may lead to visual disturbances, pupil
abnormalities, changes in sensation, muscle weakness, hearing
problems, vertigo, swallowing and speech difficulty, voice change, and
co-ordination problems. Also your heart and breathing.

By removing the amalgams and chelating afterwards the residue of heavy
metals, if the symptoms
disappeared you have your cure!

So what does this mean? How would/could this affect a persons health?

Thank you for your question too.

Forgive me for answering it by asking you one.

It has been demonstrated experimentally that metal amalgam dental
fillings generate electrical potentials with magnitudes up to 350
millivolts, see:

http://book.boot.users.btopenworld.com/dutch.htm

And the resting potential of the human neurological synapse is only 70
millivolts.

Of course, there are no muscles in the upper and lower mandibles of
the human head which might be caused to jump. However there are
sensitive organs nearby.

It makes me wonder whether people with metal fillings in their teeth
ever complain of ringing in their ears?

And if they do, do any of them refuse to accept that their condition
was caused by listening to loud rock music?

Well, it appears that the painter Vincent van Gogh complained quite
desperately of ringing in his ears. Of course, no-one told him he was
suffering from "tinnitus", because they hadn't thought of a name for
this condition back then. They just told him he was crazy.

One thing's for certain, Vincent van Gogh never attended a Led
Zeppelin show. Although apparently he did have rather bad teeth.

The widespread adoption of metal amalgams for use in restorative
dentistry was quickly followed by the rise to prominence of
psychiatric "medicine" in our societies. And presumed "explanations"
such as "manic depression" or "schizophrenia" are not explanations at
all. Like "tinnitus", they are simply terms which have been used to
denote particular sets of symptoms.

How do you think anyone would know that the real cause of problems
such as these is not the dissipation of electrical energy through the
nerves in people's heads by the amalgam fillings in their teeth?
