INDICATIONS FOR USE
For the removal of dentin, shaping and obturating of the root canal.
CONTRAINDICATIONS
None.
WARNINGS
This product contains dry natural rubber.
Rotary files are non-sterile products and must be sterilized
before use.
To prevent fire or electric shock, do not expose
the oven to moisture.
Do not remove the cover of the oven.
Do not use the oven near standing water. Dropping the
oven and/or motor into water may cause electric shock
Turn off oven and unplug when not in use.
This oven is designed for use in a dental office. Do not use
in any other environment.
PRECAUTIONS
As with all new products, you must exercise caution until you become
proficient in its use. While we have implemented safeguards against
possible misuse, there are several important points to remember:
1. A slow-speed handpiece is required for rotary file use.
2. Operate the handpiece at 300 RPM (revolutions per minute), or
500 RPM as directed for specific files.
3. Straight-line access is a prerequisite for proper endodontic treatment.
ProFile‚ GT files are no exception.
4. Always utilize minimal apical pressure. Don’t force the files down
the canal.
5. Clean file flutes frequently during instrumentation (after the file is
removed from the canal).
2
6. Frequently irrigate and lubricate the canal throughout the procedure.
7. Exercise caution in the apical area and around significant
curvatures.
8. Files are single use devices. They can become less efficient after
multiple uses causing undue stress to the file. This can lead to file
separation.
9. When instrumenting the canal, select appropriately sized
instruments as choosing an overly large file can lead to dangerous
over-enlargement of the coronal portion of narrow root forms.
Additionally, too large a file taken to length increases the risk of
separation.
10. To reduce the risk of electric shock, do not remove oven cover; there
are no user-serviceable parts inside.
11. This oven is intended for use in heating gutta-percha coated
obturators only. Do not insert anything other than an obturator into
the oven.
ADVERSE REACTIONS
Patients with latex sensitivity may experience allergic reactions to gutta-
percha, which contains dry natural rubber.
STEP-BY-STEP INSTRUCTIONS
Turning on Safe and Efficient Power
ProFile®GT rotary instruments are used in a controlled, slow-speed rotary
handpiece, thus providing the reaming action that produces a quicker,
centered, tapered preparation, while maintaining good tactile sense. A
torque control motor, such as the one included in your system, should be
used.
Procedures for Using the Aseptico ITR Motor
These are the torque settings that work best with each file series. They are
given without guarantee of risk or fracture. To avoid separation, remember
torque control motors are not a substitute for proper technique.

• SteamAutoclaveat136(±2)˚Cfor20minutes.
Crown Down Preparation
As the instrument is moved apically, it planes the walls of the canal,
smoothing and making them circular. This reaming action, in conjunction
with the variably-tapered shape, produces a “crown down” preparation
resulting in a funnel-form taper from orifice to apex – quickly and efficiently.
Additionally, dentin, which has been cut off the canal wall, is captured in
the flutes and removed while the file is taken out. The small common tip size
and maximum 1.0 mm flute diameter ensures maintenance of a small apical
reparation and predefined shape.
ProFileGTfilesfeatureflatouteredgeswithapatentedU-filedesignto
prevent self-threading of the instrument when introduced into the canal. The
flat outer edge also keeps the instrument centered in the canal, preventing
stripping and zipping of the canal.
Transportation and ledging are unlikely to occur because of the ProFile
GT file’s conical-shaped tip. Instead of a transition angle, there is a smooth
radius from the shank of the instrument to the end of the tip. ProFile GT files
are constructed from super-flexible nickel titanium, which allows creation of
a tapered funnel around curvatures, while keeping the preparation in the
canal’s original position.
Caution
Choosing an overly large file can lead to dangerous over-enlargement of
the coronal portion of narrow root forms. Additionally, too large a file taken
to length increases the risk of file separation.
Instrumentation Technique

Procedures for Using the Aseptico Endo DTC Motor
Preset torque settings are recommended for each file series. They are
given without guarantee of risk or fracture. To avoid separation, remember
torque control motors are not a substitute for proper technique.
When you remove the Endo DTC from the box, you must set the motor to
accommodate the reduction contra angle you will use. To do this, turn on the
power, and the motor automatically will lead you through the process. On
thescreen,youwillsee“1/8handpieceTUL.”Enter“2”foryesor“1”togo
to the next handpiece selection. Simply select the handpiece you will use.
You will notice the GT system technique is set as the default and is
displayed as “20 series.” Press “1” to begin the 20 series, starting with the
.10 taper and the .08 taper. Depress the foot pedal to begin instrumentation
with these files.
You will notice the contra angle reduction, RPM and torque limits are
displayed as long as you are pressing the foot pedal. To move to the 20
series .06 and .04 taper files, press “1” again and begin instrumenting. To
use the accessory files, press “1” a third and final time.
To use the 30 series files, press the “2” button, and the “30 series” screen
will appear. Press “2” again to get the .10 and .08 taper settings. Follow
the same steps used above to instrument using this file series. To use the 40
series files, press the “3” button. Again, follow the same steps as above to
advance through these instruments.
You can use the accessory files in any of the three series settings simply
by pressing that series button three times or until the accessory files are
displayed on the screen. For high-speed use of this motor, press the
“ration” button up or down until “5/1 BPR” appears on the screen. Now
you are ready for high-speed use (150,000 RPM). Refer to your Endo
DTC instruction manual for more operational features and maintenance
procedures.

File Sterilization
Files must be sterilized before use. ANSI/ADA Specification 28
recommends:
• Scrubtheinstrumentswithsoapandwarmwater.
• Rinsethoroughlywithdistilledordeionizedwater.
• Allowtoairdry.

Disinfect the canal.
• IrrigatewithBioPure®MTAD®Antibacterial Root Canal Cleanser
according to product directions.
• Thoroughlydrythecanal.
GT Obturator Selection
Irrigate and thoroughly dry the canal. Select a GT obturator the same
tip/taper as the largest GT file taken to working length. Set the rubber
stopper1mmshortofyourworkinglength.Usethelengthcalibration
markers on the obturator for setting the length. Because gutta-percha
distribution on the carrier can vary, do not attempt to set this length based
on a ruler measurement of the obturator. These calibration marks are at 18
mm, 19 mm, 20 mm, 22 mm and 24 mm.
Preparation of the Canal
GT obturators should only be placed in a canal that has been thoroughly
dried. GT-sized paper points are appropriate because they conform to these
instruments’ predefined canal shape.
After the canal has been dried, apply a very thin layer of sealer. It is
recommended that noneugenol sealers like ThermaSeal®Plus sealer should
be used with the GT obturators’ alpha phase gutta-percha. The sealer, in
addition to penetrating minute canal spaces, acts as a lubricant, enhancing
the flow characteristics of the centrally condensed gutta-percha. After
placing the sealer, place a paper point in the canal to wick up any excess
sealer.
Heating the Obturator
Heat the obturator only in the GT obturator oven. These ovens are
specifically designed to guarantee full and uniform gutta-percha heating.
Turn on the oven using the flip switch on the back. After setting the stopper,
place the obturator in the holder with the rubber stop below the holder’s
arm. Press the holder down to submerge the obturator in the heating

Note: Shaping root canals with GT rotary files generally requires one
to three files to cut the initial shape and, after gauging, one additional
file to adjust the shape, if necessary. The robust line of files allows for
shaping options up to an open apex case, which requires the use of
ProRoot ®MTA root repair material.
Gauge the apex and adjust the canal shape.

instruments are inserted straight in and pulled straight out, with no

When the GT rotary file matches the tip diameter
of the gauging instrument that bound at length,
you’re done.
Here, the #30 hand file binds at length. Therefore,
complete the shape with a 30 Series GT rotary file
of the same taper as the 20 Series GT file used to
cut the initial shape. In this example, the 20/08 GT
file was taken to length, so a 30/08 GT file will be
introduced to complete the shape.
If the #20 Lexicon NiTi hand file binds at length,
the shape is done. In this example, the #20 hand
file drops past length. Continue gauging in full
sizes (#30, #40, etc.) until the first NiTi hand file
binds at length.

chamber. Press the appropriate start button for the left or right well. The
heating time varies depending on the size of the obturator.
The first beep indicates the obturator has reached the appropriate
temperature. The oven will hold the obturator at the right temperature and
beep every fifteen seconds, up to ninety seconds, as a reminder that the
obturator is ready. The oven will automatically switch off and begin to cool
after ninety seconds.
Remove the obturator by gently pushing on the holder button and
allowing the arm to raise up.
Placement of the Obturator
In teeth with multiple canals, place paper points in the unfilled canals to
avoid overflow of gutta-percha into these canals.
After removing the obturator from the oven, place it into the canal 1 mm
short of working length using a slow, smooth, continuous motion. To remove
the handle at the orifice level use one finger to steady the handle while
severing the shaft with a Prepi®bur or high-speed inverted cone bur.
Creating Post Space
The Prepi®bur is designed to facilitate post space preparation by creating
frictional heat that removes the plastic carrier and gutta-percha quickly and
efficiently. Its smooth, non-cutting head eliminates potential root perforations.

Retreatment of the GT Obturators
Occasionally, and despite good endodontic practices, a GT obturated
case may need to be retreated. GT obturators can be removed easily by
utilizing a variety of techniques. The most common is to drill down alongside
a carrier with a .04 or .06 tapered instrument at 2,000 RPM until it binds
in the plastic carrier. Frictional heat will loosen the gutta-percha and the
spiraling forces of the rotating instrument will grab the carrier and force it
coronally.
Instructions for Using the Obturator Oven
The GT Obturator Oven has been specially developed for heating GT
(Greater Taper) endodontic obturators for use in root canal therapy. Do not
use this oven for any other purpose.
Disinfecting the Obturator
1. Disinfect the obturator using full strength sodium hypochlorite solution
(bleach) in a dappen dish for one minute.
2. Usea2”by2”pieceofsterilegauzetowipetheobturatorwithalcohol.
3. Dry the obturator for several seconds on a clean work surface to
allow evaporation of excess alcohol.
Instructions for Use
1. Plug the oven into a 110 VAC outlet. Then turn the oven on with
the power on/off switch located on the back. The green stand-by
indicator will light up.
2. Put both obturator holders in the upper position by pressing the back
of the holder (arrow up) and guiding the holder up with your finger.
3. After disinfecting the obturator and setting the rubber stop, place
the GT Obturator in the left obturator holder. Regardless of what
working length you have determined, the rubber stop must be under
the holder. Make sure the obturator is hanging straight, not at an
angle. The obturator must clear all sides of the heating chamber.

4. Push the holder down (arrow down) until you hear it click.
5. Push the button which corresponds to the size of the GT Obturator
you wish to heat. Then push the “start left” button. The obturator is
now being heated. The heating time varies depending on obturator
size and is regulated automatically.
The heating times for each button are as follows:
Size Signal Time Tolerance
.04-.08 20seconds ±5seconds
.10-.12 41seconds ±7seconds
6. After the first signal “beep,” the obturator is ready for use. Push the
obturator holder (arrow up) and guide the holder with your finger.
Take the obturator carefully out of the holder by pulling it toward
you, making sure not to scrape the obturator on any part of the
holder.
7. You may leave the obturator in the GT Obturator Oven for up to 90
seconds after the first signal “beep.” It will keep the obturator at the
appropriate temperature and ready for use. The oven will “beep”
every 15 seconds to remind you that the obturator is still in the oven.
After 90 seconds, the heating element will switch off automatically.
8. As an extra safety precaution, after you’ve taken the obturator out
of the holder, switch off the heating element by pushing the start
left button again. Keep in mind that you won’t be able to switch the
heating element off during the heating cycle.
9. If you want to heat more obturators, you may alternate using the left
and right holders to continue your work efficiently. Wait until after
the signal “beeps” for the first holder, then you may immediately
start to heat the other one. You will be unable to heat both sides at
the same time.
10. When you’re finished using the oven, use the power on/off switch
located at the back of the oven to turn it off. Then unplug the oven
until you are ready to use it again.
Cleaning Instructions
Clean oven after each use. Any gutta-percha remaining on the holder
or in the heating chamber may be effectively removed with Orange Solvent
(generic dental solvent) or any cotton pledget.
