Endo Cal - safest root canal method?

Quote from the health centered dentistry www.henryguydds.com:

"Are Endo Cal root canal treatments any better?
Yes. Endo Cal 10 is a root canal filling system that was
invented in France about 15 years ago. It has had FDA
approval for about six years. It is the least toxic filling ma-
terial known: calcium oxide. The procedure is the same as
a standard root canal, up to filling the canal. The standard
method uses gutta percha, a resin, to fill the root canals.
The resin is heated and forced into the canal where it cools
to a rubbery material. The problem with this system is that
only the large root canal is filled and the tubules are not.
Endo Cal 10 is different; it’s is a paste which is spun into
the root canals. Right at first only the large canal is filled.
Over the next few days there is a chemical and physical
change. The calcium oxide “goes looking” for water. It wants
to combine with water and will expand up to 900 times its
original size as it finds it. The net effect is that the paste
travels out through the dentinal tubules, completely filling
them. Endo Cal also kills bacteria. When it finds water, the
calcium oxide changes to calcium hydroxide and sets like
cement. After many months (maybe years) it changes to
calcium carbonate, which is what your tooth is made of.
So you end up with a solid tooth with no canals or tubules,
and most importantly, no bacteria or toxins. Endo Cal 10 is
probably the safest way to get a root canal today."

Does someone know anything about this?

There is also a document (strategies for biocompatible endo) from IAOMT that details this.

Thanks

mihai - That's pretty interesting. Here's the link to the PDF: http://www.henryguydds.com/EndoCal.pdf

I've never heard of this procedure before. Seems like it would be a much safer at the very least.

Looks like there are some ways to actually test the toxicity from the root canals (from a holistic dentist's site: http://www.hallvtox.dircon.co.uk/cavroot.html):

"A simple reliable test is available to show if a root filled tooth is toxic or not. This is the TOPAS test. The Topas test can be done immediately and the result known. A more precise test involving sending a paper point soaked in the fluid found around the neck of the tooth to Kentucky for testing. This takes longer and is more expensive.
In a TOPAS test a paper point is placed at the neck of the tooth for one minute. The point is removed and put into a solution that changes colour according to the degree of toxicity present. The solution is placed into a Colourimeter device made by Bioscience which accurately measures the change in colour and gives it a number. The process is repeated with a different solution to test for bacterial proteins. The gives a precise reading of both the severity of the toxins and the activity of the bacteria."

Although the company that makes the TOPAS test (www.altcorp.com) took down the site and now there is another site (www.altbioscience.com) that sells a similar test, but for dogs...strange. And the second test option is "A more precise test involving sending a paper point soaked in the fluid found around the neck of the tooth to Kentucky for testing". ALT corp is from Kentucky, maybe the dentist is sending the sample to the same company that developed the test in the first place.
Why aren't there more companies producing this kind of tests?

It doesn't seem right that a doctor put toxic tooth under the rabbit's skin and they died 100 years ago, and nobody else found irrefutable proof in our modern days about this. Is hard to believe something nowadays when everybody sells stuff, but it could also be true.

The problem is, what to do if one (me, for example) had root canals made years ago that don't give him any apparent trouble? Is not easy to remove what is (or seems to be) good teeth based on a test developed by a single company and without knowing for sure the tooth is really toxic. For all I know, this could be another marketing strategy like that one with the "candida spit test" (http://www.owndoc.com/candida-albicans/spit-test-candida-diagnosis-unreliable/).

Is there any other test or way around this?
