Hallo,

sehr oft höre ich, dass Quecksilber bei Raumtemperatur verdampft.
Wie ist das aber, wenn das Quecksilber im Amalgam fest gebunden ist.
Außer z. B. beim Bohren dürfte doch keine Quecksilber verdampfen, oder?

Sollte dies so sein, wären Amalgamfüllungen doch auch nicht schädlich.

Ich persönlich glaube, dass Amalgamfüllungen schädlich sind. Ich selbst habe einen hohen Quecksilberwert im Körper.
Nun möchte ich der Krankenkasse nachweisen, dass das Quecksilber vom Amalgam kommt.

Kann mir jemand einen Link oder Fachliteratur empfehlen, in der das Verdampfen von Quecksilber aus Amalgamfüllungen objektiv (wissenschaftlich) nachgewiesen ist.

Vielen Dank für die Antworten.

Grüße

Hallo Conrad,
das Quecksilber aus den Amalgamfüllungen verdampft vor allem beim Legen und Entfernen der Füllungen. Deshalb ist es doch so wichtig, Schutzmaßnahmen beim Entfernen anzuwenden, damit möglichst gar kein Hg-Dampf in den Körper kommt.

Es gibt aber auch bei bestehenden Füllungen den Abrieb bei jedem Essen, vor allem bei säurehaltigem Essen und Trinken, bei Kaugummikauen, beim Zähneknirschen. Bei diesem Abrieb ist das Quecksilber zunächst anorganisch, wird aber dann durch die Enzyme im Körper zu organischem Quecksilber, das so gar nicht gut tut.

Hallo Conrad,

Quecksilber aus Amalgamfüllungen verdampft bereits bei Zimmertemperatur. Wenn es dann im Sommer richtig schön heiß ist, braucht man sich bei noch bestehenden Füllungen nicht mehr zu wundern, warum es einem immer "relativ" schlecht geht. Man braucht also nicht Mal was warmes oder heißes Trinken, wie gesagt Zimmertemperatur reicht da vollkommen aus.

Ich habe dir mal ein paar Links zusammengestellt:

Hier ein Link, der sich kurz mit der Problematik der Krankenkassen beschäftigt:

u.s.

Kipp` einfach mal Essig oder Zitronensaft auf ein Stück Metall, egal welcher Art und lass es einwirken. Wir dürften gar nichts mehr essen und müssten den Mundraum ständig basisch halten, damit Quecksilber aus Amalgam kaum freigesetzt wird. Selbst Amalgambefürworter bestätigen seit 1989 (seit einer Untersuchung von Schiele - Befürworter), dass Amalgam Quecksilber abgibt. Schiele machte aus Vergiftungen einfach "Belastungen". Nun beschränken sie sich darauf, dass das aber nur niedrige Werte seien (Allergien dadurch wollen sie nicht kennen...)

Zudem: Abdampfen ist nur ein Problem. Auch über die Nervenkanäle und die Zahnpulpa wird es aufgenommen.

In diesem internen Dokument, erstellt von BfArM (Bundesinstitut für Arztneimittel),
adressiert an pharmazeutischer Unternehmer wird sehr gut dargelstellt,
welche Risiken und Nebenwirkungen, die niemals ein Zahnarzt erwähnt,
das "Medikament" Amalgam hat:

Hallo,

Vielen Dank für Eure Antworten.

Ich werde mir die Links am Wochenende mal genauer anschauen.

Wichtig ist, dass es objektive Berichte (Fachberichte) sind.
Ich weiß, dass die Krankenkasse den Austausch der Amalgamfüllungen nur dann zusätzlich unterstützt, wenn der Epicutan-Test positiv ausgefallen ist. Ist er allerdings nicht (wie bei den meisten wahrscheinlich). Dafür habe ich eine Allergie gegen meine drei Keramikkronen (Stützgerüst Goldlegierung) und dem Titanstift als Verankerung (macht sich als Rötung an Nase und an roten Augen bemerkbar). Ich hoffe, dass hier die Krankenkasse die Kosten übernimmt. Beim Amalgam werde ich es zumindest mal versuchen.
Vielleicht habe ich ja doch Chancen mit meiner manifesten Quecksilberbelastung (immerhin den 3-fachen oberen Grenzwert).

Ich bin Euch für jede weitere Information dankbar.

Viele Grüße
 

u.s.

Hast Du den 7-Tagestest gemacht? Metalle sind Langzeitallergene. Weltweit sind nur ca. 80 Direktallergien auf Quecksilber überliefert. Daunderer hat allein in seiner Praxis 20.000 Patienten mit Allergien auf Amalgam gehabt.

Tipp: Amalgam - Patienteninformation von Daunderer lesen. Besser noch: Handbuch der Amalgamvergiftung, da bekommt man "den Mund nicht mehr zu" beim Lesen.

Es gibt zum Thema einen sehr interessanten Beitrag kanadischer Wissenschaftler, die durch spezielle Aufnahmen das Ausgasen des Quecksilbers aus Amalgamplomben ausführlich dokumentiert und beschrieben haben. Bezeichnender Weise ist der link nicht mehr aufrufbar. Den Text (englisch) füge ich als Kopie für alle Interessierte ein. Wenigsten den habe ich damals auf FP gespeichert. Die Stunde der wissenden Verharmloser und Abstreiter hat längst geschlagen, sie wissen es nur nicht. Die Wahrheit siegt.

Über pdf geht es forumstechnisch leider nicht. Werde den Text reinkopieren.

Page 1
The video presentation titled Smoking Teeth = Poison Gas highlights more than a decade of scientific research funded by the IAOMT that is the basis for our statement of concern regarding the amount of mercury leaking from set silver amalgam fillings.
Voice Over:
All mercury/silver fillings leak substantial amounts of mercury constantly. The amount increases with any kind of stimulation and, as a result, mercury from fillings produces the majority of human exposure to mercury.1 2 3
The International Academy of Oral Medicine and Toxicology is extremely concerned about the anecdotal claims of safety by manufacturers and dental trade associations that are at variance with the published peer-reviewed scientific evidence to the contrary.4 The Precautionary Principle requires action once the possibility of harm exists. It does not require the proof beyond a shadow of a doubt that, in the case of heavy metal and
xenobiotic exposure, is both nearly impossible and unnecessary in our opinion.5
What you are seeing is mercury vapor coming off a 25-year-old silver amalgam filling in
an extracted tooth. The background is a phosphorescent screen. The mercury vapor
absorbs the fluorescent light, and you can see its shadow.6
This is mercury coming off a filling that was dipped in water that is the same temperature
as the human body, 98.60.7
This is a filling that was rubbed with a pencil eraser for just a few seconds -- like going to
the hygienist and having her clean your teeth.
These are not small amounts of mercury. If you can see it, it's more than 1,000 times
higher than the Environmental Protection Agency (EPA) will allow for the air that we
breathe.8
What about the last time you went to the dentist and they drilled on
your tooth?9 10
(Dr. Eichman demonstrates with a pocketknife)
Here is the mercury vapor every time you immerse it in 110o water
coffee or hot tea . . . or even chew on it.
Page 2
Mercury comes off fillings every time you stimulate them.11 12 13 14 15 And that
stimulation causes the mercury to continue to leak out of the fillings for an hour and one
half at a minimum.
Some people grind their teeth. Some people chew gum.
The dentist might send an old gold crown to the dental lab to be welded. How about the
dental personnel? They are not given informed consent.
Back in 1985, the International Academy of Oral Medicine and
Toxicology set out to determine the amount of mercury that
was coming off fillings . . . and here is the graph . . . showing
that substantial quantities of mercury were measured coming
off fillings.16 And then we estimated the total dose.17
Then we began animal experiments, and put
radioactive fillings in sheep. 18 Mercury
accumulated in the jaw, stomach, liver and
kidney of the sheep in just 30 days.
Substantial quantities of mercury spread
from the fillings to every organ in that
sheep's body. This should be cause for
concern for everyone.
Then we measured that the sheep's kidneys dropped in their ability by 60% to clear inulin
– an indication of kidney malfunction.19
Whole body imaging of monkeys found
exactly the same thing.20
Proponents of amalgam fillings claimed
that “sheep chew too much”.21
Well, what's the problem with monkeys?
They had mercury in their jaw, kidneys, liver, intestine and heart.
And further research found dystrophic bacteria that were antibiotic resistant cropped up
in the intestines within two weeks of receiving these mercury-leaking fillings.22 23 24
Further studies have found damage to the ADP-ribosylation of brain neuronal proteins.25
26
In response to the controversy, and at the request of the Federation of Experimental
Scientists and Biologists, Drs. Lorscheider and Vimy wrote an editorial, the first ever in
FASEB, that point-by-point refuted the claims of the amalgam
proponents.27
In 1991 the World Health Organization acknowledged that the
predominant source of human exposure to mercury is your
Page 3
fillings.28 They estimated the average daily dose from a dozen fillings is 17
micrograms/Hg.
That should be of concern to anyone wanting to have healthy children, because mercury
is highly damaging to fetuses.
Experiments in sheep showed that mercury from the sheeps' fillings transferred
immediately to the placenta, to the unborn fetus, and to every conceivable portion of the
fetus’ body.29 It even increased further in the lamb after it was born due to mercury in
the mother’s milk.30 There is no such thing as a safe mercury filling. All mercury fillings
leak mercury.
The combined effect of mercury, cadmium, and lead is just now being investigated . . .but
it is not one and one.31 One and one may make 100 or 1,000.
Why is that of concern?
Over and over again, we've heard that children are exposed to lead from our environment.
Mercury and lead together are many times more toxic than just mercury alone.32 33
These black, corroded, pitted, mercury fillings are used, where you must drill away a
third of the tooth to fix a pinhead-sized cavity.
Even if you love mercury, it's the wrong thing to do to children. It leads to broken,
diseased, root canalled, extracted teeth throughout the rest of the patient’s life. It is a
blunder that costs the child all through their life. Millions and millions of dollars are
spent annually fixing the teeth again and again.
And dentists don't follow the manufacturer’s recommendations.34 They pack mercury into
children, around gold crowns, underneath bridges. They stuff it around under the gum, in
contact with tissues.
There is mercury spreading from this gold crown to every tissue in that patient’s body.35
Even if you love mercury, putting that kind of filling in the tooth is simply the wrong
thing to do.
Dr. Harold Löe, the former director of the U.S. National Institute for Dental Research,
back in 1993 wrote, "The first filling is a critical step in the life of a tooth. Using
amalgam for the first filling requires removing a lot of the tooth substance, not only
diseased tooth substance but healthy tooth substance as well. So in making the undercut
you sacrifice a lot, and this results in a weakened tooth. The next thing you know the
tooth breaks off, and you need a crown. Then you need to repair the crown . . . and so it
continues to the stage where there is no more to repair and you pull the tooth.
"With the first filling you should do something that can either restore the tooth or retain
more healthy tooth substance. Use new materials – composites or materials you can bond
to the surface without undercuts. You can do this with little removal of the tooth
substance so that the core of the tooth is still there."36
Page 4
I would add that the cost all of that dental repair, over and over again, makes the cost of
mercury fillings enormous . . . even if we don't consider the neurological impairment and
the brain damage that they surely cause in dental personnel and the infertility and the
heartbreak that they cause to so many families.37 38 39 40 41 42 43 44 45
It is the opinion of this academy that responsible government agencies should prohibit the
use of these fillings until such time as their manufacturers produce the alleged evidence
of safety.
A presentation by the IAOMT. Our motto is: Show me the science.
The IAOMT has called for a moratorium on the use of mercury-leaking fillings.46 We
also caution patients about the careless removal of old mercury/silver fillings. If the
proper patient protection protocols are not followed, everyone present, including the
patient, the assistant and the dentist, will be exposed to high levels of poisonous mercury
vapor gas.

5. The Precautionary Principal is a new principle for guiding human activities, to prevent harm to the environment and to human health, has been emerging during the past 10
years. It is called the "principle of precautionary action" or the "precautionary principle" for short.
"The process of applying the Precautionary Principle must be open, informed and democratic and must include potentially affected parties. It must also involve an examination of
the full range of alternatives, including no action."
Thus, as formulated here, the principle of precautionary action has 4 parts:
1. People have a duty to take anticipatory action to prevent harm. (As one participant at the Wingspread meeting summarized the essence of the precautionary
principle, "If you have a reasonable suspicion that something bad might be going to happen, you have an obligation to try to stop it.")
2. The burden of proof of harmlessness of a new technology, process, activity, or chemical lies with the proponents, not with the general public.
3. Before using a new technology, process, or chemical, or starting a new activity, people have an obligation to examine "a full range of alternatives" including the
alternative of doing nothing.
4. Decisions applying the precautionary principle must be "open, informed, and democratic" and "must include affected parties."
