For polarity and amperage, hal huggins invented the RITA machine and you can buy it for around $700.  As far as vapor, the ADA/FDA has manipultaed tests to show very little vapor coming off fillings.  The video that shows the true story is the Smoking Teeth video.  I had found that Dr. Laidler of Oregon disputed that video.  But, I knew he was wrong.  So, I contacted Dr. Kennedy and asked him to write a rebuttal to Laidler.  He got together with collegues and the following is what they wrote.

THE SCIENTIFIC REBUTTAL BY DRS AND CHEMISTS AT THE TOP OF THEIR PROFESSION:

(dr kennedy filmed, produced and directed the smoking teeth video in association w/ the FIAOMT, funded by a grant from The Preventive Dental Health Association of San Diego, California. he contacted dr. boyd haley (one of america's top leading mercury scientists and chemists; for his very lengthy list of credentials, see http://www.toxicteeth.org/old_web_site/haley-CV.html), Dr. Murray Vimy, DDS, a dentist and professor of endocrinology and metabolism at the University of Calgary, Alberta, Canada. (author of Tooth Traitors), Dr. Roger Eichman, DDS (the dr who demonstated the mercury vapor release in the smoking teeth video at the IAOMT Symposium 2000 in Oxford England). dr kennedy cooberated w/ them to write a rebuttle to dr laidler's misinformation).

REBUTTAL:

Quackbuster's Analysis Fails Scientific Scrutiny:

Opinions of: Vimy, M.J., Haley, B.E., Eichman, R. and Kennedy, D.C. (2006)

Dr. Laidler’s criticism, Response to: "Smoking Teeth" - the truth gets "smoked out", reduces to the following propositions. First, he contends that what is actually being seen is water vapor; and second, since mercury is a heavier molecule than the other constituents of air (i.e. oxygen, nitrogen, carbon dioxide, etc) the mercury vapor could not rise, but would fall toward the floor. This analysis is not consistent with the Laws of Physics and Chemistry for the following reasons. First, atomic absorption spectrophotometry (AAS) is a well substantiated scientific analytical technique used to measure a wide range of elements in various materials such as metals, pottery and glass. It is based on the simple fact that some elements in the Periodic Table absorb specific wavelengths of light. This constitutes that materials fingerprint. In the case of mercury vapor the absorbance wavelength is 253.7nm.

Thus, when a pure material is vaporized by the application of heat, while specific wavelengths are sequentially shone at it, the wavelength absorbed tells one the element making up the sample. In it simplest form, gold miners employ this principle when mining for gold. In the natural state, gold has a very high attraction for mercury; the miner scratches his ore sample in a dark container, while shining an ultraviolet light. If a vaporizing shadow is cast, then mercury is present and the sample is likely gold. The amount of light absorbed is proportional to the concentration of the mercury.

The video “Smoking Teeth = Poison Gas” is simply an application of this Miner’s Test, using an amalgam filling, containing approximately 50% mercury, as the sample. Water vapor will not absorb the wavelength from the Miner’s light; and, it will not cast a shadow. Therefore, for Dr. Laidler to suggest it will is unfounded. In the video, the vaporizing shadow is caused by mercury atoms absorbing the spectrum from the Miner’s light. A light, scientifically designed to identify the presence of mercury, not water. Water vapor cannot be visualized with a 254 mm light.

Secondly, Dr. Laidler is correct when he states, “When molecules vaporize, the volume they fill depends on the number of molecules and their temperature”. This is called the partial pressure and the partial pressure for mercury in air is 0.00185 mm at 250 C. However, Dr. Laidler fails to report that the vapor pressure of mercury doubles for every 100 C increase in temperature. Employing dubious calculations, Dr. Laidler concludes that because mercury is heavier than the other components of air, if what we saw was actually mercury vapor coming off those teeth, and not just water vapor, it should have been SINKING rather than rising - even at 370 degrees C.” This of course is false, since the mercury in the amalgam is being is heated, causing the mercury molecules to become more active and vaporize. Thus, the mercury vapor rises from the amalgam and spreads into the environment in accordance with Boyles Law of Gases, the Guy-Lussac Law, and Avogadro’s Law and the Law of Entropy. These laws indicate that gas molecules by natural law move away from each other. Therefore, concentrated mercury atoms near the tooth naturally move to a location where less mercury atoms reside. These laws of the behavior of gas have nothing to do with gravity as Dr. Laidler improperly assumes.

In conclusion, Dr. Laidler reports that “ever since (he) saw the video, (he) felt that there was something wrong with it.” Indeed, he is absolutely correct! It is wrong to place materials containing 50% poisonous elemental mercury into humans, while calling them “silver” fillings. It is wrong to promote such materials as safe, when there is no level of mercury exposure considered to be “safe”. Dr. Laidler has tried to “Manufacture Uncertainty” where none actually exists.

IS MERCURY RELEASED FROM FILLINGS?
