residual bacteria or viruses, thus providing
effective root canal sterilization.
Figure 2 demonstrates the fnal fll with
the matching gutta-percha points to the veri-
fed 29 mm working length.
Case two: Maxillary left
second bicuspid
The patient presented with temperature sen-
sitivity and pain during mastication (
Fig. 3).
The treatment plan consisted of endodontic
therapy on tooth No. 13 to be followed up
with post and core treatment and an IPS

crown.
01
STEP
Local anesthetic was delivered.
02
STEP
Visual access was achieved with a #6
round diamond bur (6801.FG.018), operated
at high speed.
03
STEP
The coronal portion of the bicuspid
was enlarged with the AK10L19 fle.
04
STEP
A #15 K-fle was used to establish
a glide path, and an apex locator verifed the
working length of 20 mm.
05
STEP
The F360™ .04-taper, size-25 file
was used with a pecking motion to shape the
canal to the full working length. Lubrication
was applied throughout the process.
06
STEP
The F360™ .04-taper, size-35 file
was used, with lubrication, for final canal
preparation.
07
STEP
The canal was irrigated with
sodium hypochlorite for 60 seconds, match-
ing paper points were used to dry the canal,
and the root canal was sterilized with the
DENTA 2™ CO2 laser.
08
STEP
The fnal obturation was completed
with the matching gutta-percha points and root
canal sealer.
Figure 4 shows the final-fill
radiograph.
Case three: Maxillary left first molar
Having received treatment two weeks ear-
lier for caries control and replacement of
defective amalgam restorations, the patient
presented with an inability to tolerate hot or
cold temperatures (
Fig. 5). In addition, he
was unable to chew any type of food. Fol-
lowing consultation, the patient accepted
the treatment plan of endodontic therapy to

full-crown coverage.
01
STEP
As in the previously presented cases,
radiographs were taken, local anesthetic was
applied, and digital working-length measure-
ments were taken.
02
STEP
The access opening was completed,
and the canal was enlarged with the AK10L19
fle.
03
STEP
The #15 K-fle was used to develop a
smooth glide path, and the working lengths
were verifed with an apex locator. In this case,
the working length was 21 mm for the mesio-
buccal and distal-lingual canals. The palatal
canal had a working length of 23 mm.
04
STEP
The canal was shaped with the .04-
taper, size-25 fle, again using lubrication and a
pecking motion. Note: Remember to limit your
handpiece to 350 rpm or less and use 1.8 torque
value.
05
STEP
The fnal preparation was completed
with the .04-taper, size-35 fle. The preparation
was irrigated and sterilized as previously
described, and the final obturation was
completed.
Figure 6 shows the fnal fll radiograph.
Closing thought
Typical of the types of endodontic cases seen in
most dental offces, these cases each presented
differently, yet they successfully responded
to standard F360™ endodontic therapy. The
two-file technique that follows access open-
ing and coronal enlargement can be used for
up to 80 percent of the root canal therapies
most dentists prescribe, thus making standard
endodontic treatment predictable, effcient and
straightforward. This translates into signifcant
time savings, which in turn leads to increased
proftability in the dental practice.
