Quoting Professor Daunderer
(Ecomed Verlag, Landsberg 1998 isbn 3-609-71750-5)

"If we take Multiple Sclerosis patients who removed amalgam
but refused both extraction of root canals
and treatment of infected maxillary bone,
we observe a cure rate from MS of 16%

But when we consider multiple sclerosis patients
that beside amalgam removal accepted our full treatment
(root canal extraction and cleaning of alveolar bone),
the percentage of cures increases to 86%."

Daunderer in the 1998 TV show by Sabrina Giannini:
"The dental work we get from dentists is not something biological or medical.
I'd say it is a technical thing, and the technique give the dentists
a number of very strong poisons to be implanted in the mouth.
If you kill the tooth and then fill its root canal with mercury,
formaldehyde, cortisone, streptomycin, arsenic
... you are not doing an healthy thing.

All this dentistry is just a sin against the biology of the body
and a sin against the 'real' medicine."
