Negotiating around anatomic impediments
Tactile clues, bypass techniques, procedural flow
By L. Stephen Buchanan, DDS, FICD, FACD
Impediment [im-ped-uh-muh’nt]
1. Obstruction; hindrance; obstacle.
Perform endodontic therapy on 10
molars and chances are you ran into at
least one anatomic impediment. Despite
the significant occurrence rate, few of us
have been taught how to identify and
manage apical impediments, let alone
those that occur in the coronal third.
Without a clever technique for these
cases, the right instruments, and an accurate mental image of the canal space
you are in, you have virtually no chance
of reaching the end of the root canal
space, significantly increasing the chances of persistent apical infection. With the
right stuff, managing these endodontic
challenges can be a fascinating procedural experience requiring little extra
time and delivering remarkably predictable outcomes.
Let’s begin with a look at the different
types of impediments.
Anatomic impediments
1. Apical irregularity at the terminus of
a relatively straight canal.
2. Irregularity on the outside wall of a
curved canal.
3. Abruptly curved canal.

Iatrogenic impediments
1. Apical blockage.
2. Apical ledging.
3. Remnant of instrument.
How do you know you have met an
impediment? That’s easy: by the tactile
sensation felt as loose resistance to file
advancement. Tight resistance to file
advancement is the sensation felt when
a file moving apically binds and then exhibits tug-back upon removal. Tight re-

sistance means the file is binding on two
opposite sides. Usually in this case, working the file (push-pull, balanced force, rotary, etc.) will allow it to progress apically.
Loose resistance to file advancement
means that the file tip is caught either in
some type of an irregularity (lateral canal, isthmus, fin), or the file tip is bumping into the outside wall of an acutely
curved canal. All that remains in the
diagnosis of apical impediment is to apply an apex locator (Fig.1) lead to the file
‘History & Heritage — Forging the Future’
AAE’s 2012 Annual Session to be held April 18-21 in Boston
See page B8
and confirm a short reading (and obviously an apex locator is the best method
of determining when you have actually
reached the Holy Grail — length).
OK, so how do we deal with the aforementioned impedimento?*
First off, we do not ever attack or even
firmly engage an impediment with the
tip of any instrument. That’s how ledges
happen, and a ledged canal is waaaay

Root Canal
Awareness
Week
While 63 percent of Americans would
like to avoid getting a root canal, even
more, 69 percent, want to avoid losing a permanent
tooth,
according
to a recent survey
by the American
Association of Endodontists (AAE).
During Root Canal
Awareness Week,
March 25-31, the
AAE wants to dispel myths sur- ‘It’s important to

nal treatment and their natural teeth

techniques and magnification technology maximize the potential for a comfortable patient experience and successful
treatment outcome.
“It’s important to patients that we save
their natural teeth whenever possible.
Putting them in the hands of qualified
specialists is a win-win for the patient
and the dentist,” says AAE President Dr.
William T. Johnson. “By referring patients to an endodontist, dentists demonstrate the concern they have for quality
and outstanding treatment of each individual in their care.”
More than half of Americans, 56 percent, say root canals are the dental procedure that makes them most anxious,
according to the AAE’s January survey
of 1,014 U.S. adults. A dentist partnering
with an endodontist can put patients
more at ease, and when dentists refer
their patients to endodontists for root
canal treatment, the patients are more
likely to be satisfied, according to a 2007
national consumer survey.
Endodontists and general dentists have
always enjoyed positive partnerships,
with 94 percent of dentists reporting a
very positive or positive perception of
endodontists. The AAE video, “Endodontists, Partners in Patient Care,” features
general dentists discussing the positive
relationships they share with their endodontist colleagues. It is a great resource
to show patients when a referral to a specialist is needed.
The AAE also provides general practitioners with many educational resources
that encourage high standards of endodontic care and support collaboration.
Treatment Options for the Compromised
Tooth: A Decision Guide includes case
examples with radiographs of successful
endodontic treatment in difficult cases
and is designed to encourage general
dentists to assess all possible endodontic
treatment options before recommending extraction. The Case Difficulty Assessment and Referral Form can be used
to evaluate a patient’s condition and assess risk factors that may affect the outcome of treatment. Biannual mailings
and online archives of the ENDODONTICS: Colleagues for Excellence newsletter highlight clinical topics of interest to dentists who perform their own
endodontic treatment and benefit from
coverage of best practices and the latest
advancements in the specialty.
By using these tools during Root Canal Awareness Week and throughout the
year, general dentists ensure they are
developing the best treatment plans to
save natural teeth, and keeping patients
happy.

Ask your dentist about an endodontist who specializes in root
canals to ease your fears and save your natural tooth for a lifetime!
For more information about root canals and to find a root canal
specialist, visit www.aae.org.
The AAE has made this poster and many other resources available online. Photo/AAE
“Our main goal as endodontists is to
provide patients with a seamless transition between their dentist and specialist
through emergency care, timely treatment, appropriate follow-up and referral
back for restorative treatment. Communication and collaboration between the
doctors is an essential component of the
partnership,” Johnson says. “At the end of
the day, patients want to know they can
trust their dentists to do the right thing
for them at the right time — it’s our re-
sponsibility to earn and maintain that
trust.”

AAE selects endorsed website provider
The American Association of Endodontists (AAE) has selected dental website provider PBHS Inc. as the endorsed
website design firm for the association’s
7,400 members. The company will provide its endodontic custom and semicustom website development services to
participating AAE members.
“The powerful combination of PBHS expertise in website design and AAE’s leadership in the endodontic specialty will directly enhance the practice growth and patient
satisfaction of the AAE membership,” said
Jay Levine, president of PBHS. “With over
30 years of experience providing patient
education and marketing services, PBHS
can equip participating endodontists with
a high-impact, interactive website that preeducates patients, promotes the practice
and facilitates treatment planning.”
PBHS website packages cover every
endodontic procedure with detailed animations, time-saving patient presentations, AAE informational libraries and
proven search engine results. PBHS also
offers powerful enhancements such as
secured online patient registration, re-
ferral collaboration, and practice management software integration.
A 2011 AAE Member Survey exploring
practice busyness demonstrated that 58
percent of member endodontists do not
currently have a website presence; a related survey of member needs showed
that a majority of members would appreciate the AAE’s endorsement of a custom
website design and hosting firm. The goal
of an AAE endorsement for website design services is to assist endodontic professionals with outreach to current and
prospective patients, as well as referring
dentist partners.
“Our goal is to provide AAE members
with services that will enhance the growth
potential of each practice, enabling them
to take advantage of all available technologies for patient education and the development of strong referral partnerships,”
said William T. Johnson, AAE president.
“Helping our members choose a trusted
partner for website communications is a
step we’re very excited to take.”

“ IMPEDIMENTS, Page B1
more difficult to manage successfully
than just a severely curved canal. Aspire
to the maxim, “If you can’t fix it, don’t fix
it so nobody else can fix it.”
Managing impediments is all about
file bending, mental visualization and
patient, skilled technique. So let’s discuss file bending.
When and how to bend negotiating
files
You might be surprised to read that I
find it unnecessary to slightly curve
all negotiating files before use — a
method most of us were taught. Due
to their exceptional flexibility, unbent
K-file sizes smaller than #15 will easily traverse impediment-free canals with
greater than 90-degree curvatures (Fig. 2).
Try using only straight negotiating
files for a time — assuming you negotiate through a lubricant and start

with an 08 K-file in small canals. You
will be amazed at how often you get
to length without bending them. At
the end of the day, using cotton pliers

an impediment.
with that ribbon-curling motion on
your smallish files is a waste of time,
so my advice is to stop yourself. You
don’t have to do that anymore. Not do-
ing that could save weeks of your life
over a career.
Mental imaging
To understand this better try this
thought experiment:
Be the file.
Imagine that you are the negotiating
file moving into a canal. You have a subtle curve along your whole length, and
because you are being used in a watchwinding motion your tip is waving back
and forth “scouting” loosely through the
canal — and, just as estimated length
nears, “dink, dink” — loose resistance
to apical advancement! Shoot! We pull
back, re-approach and get the same result, regardless of how we manipulate
the instrument (Figs. 3, 4).
To better understand why this has occurred, ribbon-curl a #10 K-file with cotton pliers along its full length and then
clamp the file with a hemostat about 4
mm back from the tip. Look at the tip
portion with magnification and you will
see an essentially straight instrument
tip. And this is the part of the file that is
supposed to make its way around a canal
path that is radically more bent.
Another way to say it is that the file
tip was not bent acutely enough to keep
the file tip centered as it moved into the
tightly breaking canal curvature. When
a file is curved 25 degrees along its whole
length, it will never make it around a canal curvature that is 90 degrees along its
last 1-2 mm.
Clever technique
Mentally imaging the canals you are
treating, coupled with the use of appropriately curved files just needs a bit of
clever technique to conquer the apical
impediment. The first clever technique
trick is to pre-bend the last 1-2 mm of the
file with an EndoBender (SybronEndo)
(Fig. 5), look down the length of the file
and carefully adjust the indicator on the
stop (notch, line or point) to be in line
with the bend of the file.
Now, as you scritch-scratch into the
canal, hunting for the path of least resistance, you feel and see the file passively drop deeper into the canal as
you advanced in a new direction. Now,
after you have successfully snaked the
file around this one-of-a-kind, difficult
anatomy, the next question is “How will
I get back here with my next instrument?”
All you have to do is to look at the indicator on the stop, note the direction and
after bending the next file and aligning
the stop to the bend, you simply move
the file to length with its bent tip point-

ing in the same direction as the previous
file to length.
Dr. L. Stephen Buchanan was valedictorian of his class at the University of the Pacific School of Dentistry, and he completed
Final advice
• Remember that there is little forgiveness in a tightly curved canal, so
for goodness sake, do anything to avoid
blocking the end of the canal. Most often,
compacted blockage at a canal curvature
will never allow re-entry along the original canal path, so, despite a lot of effort
spent attempting to regain patency, the
most likely outcome will be apical perforation with these small instruments.
• Use an apex locator, or you are working waaay too hard without a clue as to
where you are. Is that acceptable to you
when you could spend less time and definitively nail length with an apex locator (Fig. 6)?
• Never initially thread the apical half
of a small canal with larger than a #08 Kfile. Never negotiate any canals without a
lubricant in the access cavity.

the endodontic graduate program at Temple University in Philadelphia in 1980. He
began pursuing 3-D anatomy research early in his career, and in 1986 he became the
first person in dentistry to use micro CT
technology to show the intricacies of root
structure. In 1989 he established Dental
Education Laboratories, through which he
has lectured and conducted participation
courses around the world. Buchanan holds
a number of patents for dental instruments and techniques, including variably tapered shaping instruments for use in endodontics. He pioneered a
system-based approach to treating root canals. He is a diplomate of the
American Board of Endodontics. He maintains a private practice limited to
endodontics and implant surgery in Santa Barbara, Calif. Contact him at

• Once you battle your way to length
with that tiny first instrument, don’t
just get patent a mm out the end of the
canal — in this case I suggest you go 3-4
mm long and do 30-40 push-pull filing
strokes to loosen the file and slightly en-
large the canal. This act will greatly improve your chances of avoiding blockage
with the next largest file. There are few
experiences more frustrating than to
have cleverly and heroically battled your
way to length through a hideously tortuous root canal, never to return again.
• Distal canals of lower molars and DB
canals in upper molars commonly have
severely, abruptly curving canals enclosed inside remarkably straight external root structure. Look for loose resistance to apical advancement, when you

feel it whip that instrument out, bend
the very tip just short of 90 degrees, adjust the stop indicator, and go hunting!
Blocking, ledging or just never getting
to the terminus because of a mishandled
impediment is not the end of the world,
but it’s not the end of the canal either.
Gone are those halcyon days when we
could get away with telling curious patients that blocked canals were calcified
apically. Never mind, apply these principles (Fig. 7) and I’ll see you at the apex!

EDS expands instrumentation line with 31 mm SafeSiders
Essential Dental Systems (EDS) has expanded its line of endodontic instrumentation products by now offering SafeSiders in 31 mm length to meet the needs
of dentists seeking longer instrument
lengths.
The SafeSiders are a series of patented
flat-sided instruments that were designed
by endodontists to eliminate the fear of
separating instruments. SafeSiders reduce instrument engagement in root canals, allowing faster advancement with
less resistance. These instruments can be
pre-bent in order to conform to any canal shape. SafeSiders reduce instrument
stress, improving durability. Dentists
can experience increased instrument
flexibility without needing to sacrifice
strength.
For the first time, dentists are able to
replace instruments when they dull, not
because they fear breakage. SafeSiders
are an affordable solution for endodontic
root canal therapy. All SafeSiders can be
used by hand or in the Endo-Express reciprocating handpiece. SafeSiders instruments are also available in 21 mm and 25
mm lengths.
The new SafeSiders instruments are
available immediately and can be ordered through dental dealers in the United States, Canada and throughout the
world. For more information on this or
any other EDS products, contact Victoria
Reina, sales and marketing manager, at
(201) 487-9090.

canals that require
a smaller instrument to gain initial
access to the apex
in the beginning of
endodontic instrumentation.
They are available in 21, 25 and 31
mm lengths.
Munce Discovery Burs from CJM Engineering
Munce Discovery Burs are the answer
to calcified canals, separated instruments, isthmus troughing, cement-line
dissection and deep-access caries.
Shallow and Deep Troughers are 31 mm
and 34 mm long, respectively, with six
easy-to-read, color-coded round carbide
head sizes (#¼, #½, #1, #2, #3 and #4).
There is also the unique 31 mm-long #6
Endodontic Cariesectomy Bur.
Stiff 1 mm-diameter shafts ensure positive operational control, and the even
narrower 0.7 mm-diameter stiff shaft (on
the smaller head sizes) is ideal for highmagnification delicate isthmus troughing and cement-line dissection around
posts, silver points, etc.
Munce Discovery Burs

By contrast, standard slow-speed burs
are only 28 mm long and have bulky 2.6
mm-diameter shafts that impinge on
deep access cavity walls, unfavorably
guiding the bur head
toward ledging or perforation.
Unlike
ultrasonic
tips, Munce Discovery
Burs are heatless, not
prone to spontaneous
breakage and have the
familiar tactile feedback of slowspeed
round burs.
