Advances in diaphanization
and photography reveal
wonders of pulp chamber
Author_Fred Michmershuizen, Managing Editor
_Many readers will be familiar with Craig Barrington, DDS, whose photography has been featured
on the cover of roots a number of times over the
years, including the issue you are looking at now. His
images also appeared in Endo Tribune along with an
Fig. 1_The dual color stained
vascular distribution with the
pulp chamber of a lower first
molar. In the center bottom
portion of the chamber we see a
very large vessel structure. It’s
these large vessels lying on the
chamber floor that create the
well-recognized dentinal map.

interview (see “The immense variability of human
tooth anatomy,” Endo Tribune, December 2016, Vol.
11, No. 4, Page 1).
Since that article appeared, Barrington has refined and improved his technique even further, with
results that are often even more
breathtaking in scope and sheer
beauty. Barrington’s photographs
of the interior of teeth often reveal
vasculature that is more complex
than has previously been revealed.
Some of the images resemble
other forms in nature, such as
the branches of a tree, or a river
and its tributaries, or even a coral
formation.
In a new interview with roots
conducted in October 2020 via
web conference and email, Barrington shared and described
some of his more recent images
(Figs. 1-3), and he offered some
of his own insights on the complexity of this particular aspect of
human anatomy.
For those who are learning of
you and your work for the first
time, can you please give us a brief
explanation?
I use diaphanization, which is
the exposing of a former living
tissue to a series of chemicals and
processes to make it transparent.
This is how organs were viewed in
3-D prior to the computer technology we have today. The initial
process was created by Werner
Spaltholz in 1906. The process
was introduced to dentistry via
[5] =>

publication in the Dental Cosmos in 1913.
Your work has been featured on the cover of
roots before, and you also gave an interview to
Endo Tribune a few years ago that was illuminating as well. How have you refined your technique
since we last spoke?
Oh wow! I crossed in to a new dimension that
I never knew was possible. As you see, I have
been able to repeatedly expose not only the
canal systems of a human tooth but the internal
structures in the form of the vascularity and
the nerve all in the same specimen. I have been
able to do this in a repeatable and reproducible
fashion. It has occurred out of pure luck, intense
repetition, astute observation and ultimately
through learning from error.
How long have you been photographing
teeth in this manner?
For more than 20 years now. But the recent
photographs are also of a completely new
method that came about through luck, reading,
repetition, observation and failure.
How long does the diaphonization process
take?
This depends on the structures one would like
to view vs. the initial starting point of the specimen acquired. If someone wants to view the results of a failed, extracted tooth root canal then
it doesn’t really matter how the tooth was acquired or whether or how the tooth was stored.
With teeth like this, a result can be achieved in 12
to 24 hours. If one would like to achieve a result
where the vascularity/nerve are visible, then the
collection and storage have specific parameters
that need to be followed. Overall, a result can be
achieved in about five to seven days from the
acquisition of the specimen.
What has surprised you the most about the
human anatomy since you started creating
these images?
There is still so much we don’t know. We think
we are in control, but we are very much not anywhere close to understanding the human body and
its functions.
Has your work in this area changed your understanding of dentistry in general?
I have taken a turn in a direction that dentistry is
not going. I have seen things, entities and formations
that no one else has ever seen before in dentistry.
I have had time to think about these observations
and possibilities that could come about in our clinical options. Currently there is no research, materials
or methods to approach the pattern of results in Fig. 2_The vascularity of many upper
second molars is very dense in many
anatomy that I have seen.
In your view, how can dentists and specialists
benefit from studying these images?
We should be working to aid and/or repair the
tooth in healing itself vs. removal and replacement
of these structures.
cases regardless of the age of the
patient. Through the center of this
pulp chamber we see a return flow
vascular body.
The vascular anatomy is quite pronounced in your
images. Do you see any uses in dentistry, or in medi-

cine in general, for how the harvested teeth might be
used now or in the future, aside from photography
and study?
The list is so long that it’s hard to know where to
start. For one aspect, teeth are being extracted and
discarded as trash when inside are blood vessels that
could be harvested, grown and used in other parts of
the body. This doesn’t just have to be a wisdom tooth.
There is quite a bit of vascularity in every tooth and
at every age group.
In another area, the effects of medication on the
dental pulp needs to be analyzed, as I have already
achieved results that expose the vascularity of the
pulp and there are some unusual appearances. It is
my very initial hypothesis that one of the medications
patients are taking is altering the blood flow in their
teeth. This could be used to the advantage of some
other attribute in medicine or at least be an aid in the
tooth healing itself via a medication the patient takes
vs. having a root canal in a clinical setting.
This list is long, so to cover all of it here would be
difficult. But how is that for starters?
Your pictures would not be out of place in an art
gallery. What do you think?
Probably the first reaction I get from many people
is that they immediately see artwork and want to
make a picture to hang on a wall. I find that admirable, but it honestly overlooks and somewhat negates
that we need to understand that these are human
body parts.
It has been my wish and demand that these images not be used as art or for profit but that they be
viewed from a scientific basis such that we advance
humanity, dentistry and/or medicine and the benefit
of all suffering from conditions and/or illness.
I think this quote, from Pope John Paul II in his
encyclical Evangelium Vitae, applies: “Respect for life
requires that science and technology should always
be at the service of man and his integral development.
Society as a whole must respect, defend and promote
06 I roots
2_ 2020
the dignity of every human person, at every moment
and in every condition of that person’s life.”
Do you have plans to publish these photographs?
I have a book in the process of being published
with Quintessence. We have a few more months
before that gets completed, but then I hope to start
on a second, follow-up edition.
Do you have anything you would like to add?
I would like a full-time job researching internal
anatomy of human teeth. We need more results
and observations in the realm of patterns and associations with various systemic conditions and
medications.
Currently all the results achieved have been as a
result of my efforts working mornings, evenings and
weekends around a full-time active dental practice.
Even if I could work two to three days in a row undisturbed and with help, the results could be increased
tenfold from what I’ve been able to achieve on my
own, on the time I have available.
There is no doubt that this work could benefit
humanity on many aspects and horizons._

AAE conducts
media tour on dental
emergencies during
COVID-19
Author_ AAE Staff
_To help increase awareness about the crucial work endodontists are performing during the
COVID-19 pandemic, American Association of Endodontists President Dr. Alan H. Gluskin recently completed a media tour in which he delivered a message
about the importance of seeking treatment for dental
emergencies.
Gluskin took part in 24 unique interviews —
with many more airings than that, thanks to a
self-contained interview, which was picked up in
several media markets throughout the country. In
addition to the interviews, Gluskin released video
and audio news releases to drive these important
points home.
In total, the media tour yielded 387 broadcast
TV interviews and 146 radio interviews. There
were 1,023 distributions of the video online, with
1,612 total placements and 255.4 million total
impressions.
As Gluskin explained to the public, endodontists
are the dental specialists who focus on root canal
treatment and saving teeth. He said that more
than 90 percent of endodontic practices are fully

H. Gluskin, shown at right during a
recent satellite media tour.
reopened now, and most of these specialists were
open for emergencies even during the height of
COVID-19, reducing the need for patients to seek
emergency dental care at ERs and urgent care
facilities.
Gluskin also advised patients not to delay routine
check-ups with their dentists. Putting off preventive
care will only make dental issues worse and could
potentially lead to long-term issues with teeth and
gums, he said.
To make offices as safe as possible, AAE members
have been adhering to all guidelines put forth by the
AAE, ADA and CDC, creating a well-protected office
experience for all patients in need, Gluskin said.
Questions answered by Gluskin included the following:
• What constitutes a dental emergency? How do
you know if you need an endodontist?
• What is the “rubber dam” and why is it important,
especially in the era of COVID-19?
• Along with the standard safety and sterilization
precautions regularly implemented, what additional
prevention steps are endodontists’ offices taking?
• What can patients expect when visiting a dental
office?
• What preventative care should people be practicing during the pandemic? Where can I go for more
information about COVID-19, emergency dental care
and finding an endodontist?
Gluskin also emphasized AAE’s efforts to help keep
emergency rooms clear for those who need them by
helping dental patients find the right professionals
in cases of dental emergency. Gluskin talked about
the AAE’s Guidelines on Dental Emergencies and Oral
Health through the coronavirus pandemic and directed viewers and listeners to seek emergency dental care from endodontists first, rather than visiting
hospital emergency rooms or urgent care facilities.
_AAE’s new dedicated Newsroom website
The AAE also recently launched a Newsroom web-
08 I roots
2_ 2020
site, located at https://newsroom.aae.org, designed
with the media and public in mind. The new site is
designed to serve as a meaningful way to elevate
endodontics and endodontists, and it touts the importance of saving the natural dentition through root
canal treatment.
“In recent years, the AAE has created an abundance of award-winning engaging content clearly
outlining the important work endodontists do,
and now we have a digital home for it all,” Gluskin
said. “This new site is much more than a repository,
however. It is a dynamic site and will continue to be
updated as we release several more public-facing
activations in the coming year. This is just the beginning.”
Recent years have put the AAE on the map in
terms of creative media and communications.
From the installation of a chief marketing and
communications officer, to the development of a
full marcom team, to the launch of a major public
campaign — this has all led to now, several awards
later, as the AAE is ready for a dedicated newsroom
to serve as a useful media hub, the AAE said.
The Ask the Expert section allows journalists
on deadline to get questions answered quickly
— directly from AAE member and Public and Professional Relations Committee Chair Dr. Mark B.
Desrosiers.
AAE members and dental professionals will also
find the site useful, as it includes many downloadables, such as videos, infographics and fact sheets, the
AAE said.
While aae.org/patients is the AAE website geared
toward the public, any patients who find themselves
at newsroom.aae.org will likely find it useful as well,
the AAE said.
“I highly recommend everyone gets to know
our new Newsroom site,” Gluskin said. “Head over
to newsroom.aae.org and stay a while. There’s
something there for everyone to gain, and it really sets the stage for our exciting future creative
plans.”_

AW-100 Sonic
Endodontics
handpiece
Author_Micron Corp. staff
_The AW-100 is an air-driven handpiece specifically designed for root canal preparation and
irrigation. Its major characteristics, as described
by Micron Corp., the company behind the product, are as follows.
The AW-100 provides users effective and efficient root canal treatments, the company said.
Especially the strong sonic vibration (2,0003,000 Hz) greatly exhibits a high irrigation effect
in root canals. The vibration generates highspeed stream and bubbles of water, and those
are delivered to the entire root canal including
accessory canals and isthmuses to wash off
smear layer, pulp tissue and debris. This is the
key to the long-term success of endodontic
treatments.
The AW-100 has a power control ring, and
it can adjust the sonic vibration to suit instruments in use or root canal shapes.
The very compact head of the instrument
holder allows fine-tuned treatments and easy
access to root canals without obstructing the
view. It is also effectively used for treatments
under microscopes, the company said.
The instrument holder is adaptive to various
types of rotary files with a shank diameter of 2.35
mm, which a lot of endodontists frequently use.
Users can choose the optimal file according to
the treatment plan.
The AW-100 is a patient-friendly device, the
company said. It is powered by compressed air,
so it will not generate electromagnetic waves
that could affect the human body. It is safe to
use especially for people who have pacemakers,
the company said.
Micron Corp., manufacturer of the AW100, was established in Tokyo in 1976. Its core
technology is the air-driven sonic vibration
system based on aerodynamics, and that has
been utilized in all the company’s products,
such as endodontic handpieces, air scalers, air
polishers and three-way syringes. Micron Corp.
prides itself on providing the highest quality
products and it will always take into consideration clinical benefits to users and patients, the
company said.
