4.5.15.3.7 Using reciprocal rotating files
For endodontic treatment with reciprocal rotating files, the sequence of
the files and the preset values recommended by the manufacturer cannot
be changed.
When switching to the
the speed and torque and the counterclockwise key are hidden.
As long as the dental treatment unit is equipped with the ApexLocator
option, it can also be used with reciprocal rotating files.
4.5.15.3.8 Using the ApexLocator
✔
The dental treatment unit is prepared for apex measurements using
the instrument, see section "Preparing to use the ApexLocator"

1. Select a file, see "Selecting a file" [ → 131]. If necessary, change the
preset speed and torque, see "Setting the speed and torque" [ → 135].
2. You can make a setting to ensure that the motor stops automatically
at a preset distance from the apex. If you want to use the automatic
motor stop, this can be preset in the
automatic motor stop can be combined with the
function, see "Setting the automatic motor stop of the ApexLocator"
[ → 139].
IMPORTANT
Preventing incorrect measurements
When performing the apex measurement, wear non-conductive gloves
to avoid measurement errors caused by unwanted leakage current.
During the measurement, the instrument must not come into contact
with the patient's mucosa, metallic tooth restorations, or the mucosal
electrode. It is recommended to pull the silicone isolation sleeve over
the handpiece and perform the treatment using a cofferdam.
3. Attach the previously selected file to the handpiece.
4. Short the electrical measurement system. Plug in the files and hold
them directly against the mucosal electrode. This cancels out any
inaccuracies caused by jumps in impedance in the measurement
setup (standardization).
 If a short signal is heard and the distance display appears with no
bars, the standardization was successful. If not, check the
electrical connections for signs of damage.
5. Place the mucosal electrode in the patient's mouth and perform the
treatment. Activate the bur using the foot pedal.
 The measured root canal depth is displayed by a colored bar in
the distance display. The maximum root canal depth reached is
displayed by a black triangle to the left of the distance display. To
the right, the distance of the motor stop set in the
program is displayed. For more information, please refer to
"Distance display" [ → 97].
