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.

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

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.
