FORMALDEHYDE IN DENTISTRY
The Irrational Fear of a Human Endogenous Substance by
Pasquale Durino, DDS
The world has seen many problems with man-made chemicals such as thalidomide, PCB’s, DDT etc. In many people, this has sparked a fear of all chemicals, including many that are naturally occurring. Members of the scientific community are not immune to these fears. Formaldehyde in dentistry is a classic example of the irra- tional fear, in the scientific community, of a substance that is present in every cell in the human body. There is significant controversy among formaldehyde researchers about the connection of formaldehyde to cancer in humans but one common theme seen in their research is that formaldehyde is a concern only in high concentrations. A review of the literature and a knowledge-based approach should allay the fear of the use of this substance in quantities that are used in dentistry. Formaldehyde is an essential part of human cellular function. The dental community should be reminded that the investigation of naturally occurring substances, with which we have evolved over thousands of years, is very different than that of man-made chemicals. It is also essential to remember that any discussion on the toxicity of a substance must be related to dosage.

An Endodontist Reveals Myths
and Half Truths Behind The Sargenti Controversy by Dr. Patrick Wahl
HALF-TRUTH: N2 is toxic.
WHOLE TRUTH: All sealers are toxic,1 but a basic
tenet of toxicology is that “the dose makes the poison.”
Indeed, the recognized scientific phenomenon of
“hormesis” means that hazardous chemicals at low
doses are not just harmless but can even be beneficial.
Nutrients like salt and vitamin D are poisons when used
in large concentrations, yet they are essential for life.
Fluoride is also a potent poison in large concentrations.
Coumadin is a well-known blood thinner that many de-
pend upon to live; it is also available in higher concen-
trations as rat poison.
AAE has sensationally compared N2 to “embalming
fluid.”2 N2 is 4.5% formaldehyde; embalming fluid is
40%. Formocresol, the pulpotomy agent and intracanal
medicament advocated in my endodontic training at the
University of Pennsylvania, is 19% formaldehyde. Even
Dr. Larz Spangberg, a critic of N2, has stated that the amount of formaldehyde in a root canal is negligible
from a toxicological point of view and that the exposure

N2 Now The Preferred Root Canal Treatment
Four Swedish dentists, Drs.
Niels Norsell, B. Cederbloom and Stefen and Bengt Nordstrom, have succeeded in
having the Swedish Board of Welfare reverse their ban on the use of N2 Root
Canal Sealer in Sweden.
For years the endodontic specialists have used their influence in only
allowing conventional root canal
sealers to be used in Sweden.
The Swedish Board of Welfare have now enough evidence to show that conventional root canal has high failure rates, but has
cost the Board of Welfare large sums of
money to pay for these root canal treatments, which have resulted in wasted
money and large numbers of tooth extractions.
Evidence has now been accepted, that using N2
treatments is more successful in root canal treatments, but would have resulted in
a higher success rate, less health risks and at less cost to the Board.
Root Canal Treatment
In most European countries, the general
practitioner in the daily routine has to deal with a root canal problem.
Treatment is time-consuming and difficult. Out of this reason, a special
has developed in certain high-class and rich markets, that is the endodontists specialized in
treating the root canals with special knowledge and good success. The only problems are the
high price, which is needed, and the fact that social security ensured people
cannot pay for this treatment. For this reason, general practitioners in most
European markets use a fast and easy treatment by quick cleaning of the canal followed by
filling with a spiral drill (lenrulo) with a root canal cement, or better
called root canal sealer, by the name of N2. N2 contains a very low rate of
formalaldehyde, not more than you'd find in a large glass of milk. Unluckily, over
the years decisions were made in certain markets to ban this product and take the
possibility away from general practitioners to treat the public with this
been used throughout Europe for over 50 years.
This did not matter to people who are
able to pay for the endodontist treatment. The fast N2 technique used by
10,000 dentists was excluded in certain markets, e.g. in Sweden, partially in Poland and possibly in other markets.
Now the decisive government agencies have recognized
this problem and have officially reinstated the N2 technique with an official announcement in the Swedish Dental Journal.
We think that with this move the state will
save a lot of expenses because instead of extracting the root canal
infected tooth, the general practitioner will start trying to save this tooth
any high-price crown and bridge work in the future.
