FOR DENTAL USE ONLY
DIRECTIONS FOR USE
Introduction
Congratulations on the purchase of ProPex®II.
1. Indications for use
ProPex®II is an electronic device used for apex location determination and working
length determination. This product must only be used in hospital environments, clinics or
dental offices by qualified dental personnel.
2. Contraindications
The ProPex®II is not recommended for use in patients that have a pacemaker or other
implanted electrical devices.
3. Warnings
See above.
•Only use the original charger

4 / 71
4. Precautions
The ProPex®II device must be used with the manufacturer's original accessories only.
In order to prevent infectious agent transmission it is highly recommended to use a rubber
dam system during the endodontic procedure.
To ensure that short circuits do not impair the measurements, be particularly careful with
patients fitted with metal crowns or bridges (avoid any metallic contact with the file or the
lip clip)
•High concentrations of sodium hypochlorite may result in a lower accuracy. For
working length determination, we recommend to use sodium hypochlorite solution at
maximum 3% concentration.
•Make sure that the canal is wet enough to ensure reliability of the measurement
•Ensure that the file does not touch another instrument.
•Do not expose ProPex®II to any liquid.
•Avoid excessive liquids inside the tooth cavity to prevent overflow and incorrect
measurements.
•ProPex®II must be stored in normal temperature (< 60 °C) and humidity conditions.
•Do not use in the presence of flammable products.
•Teeth with open apices will give imprecise results.
•If the bar graph suddenly makes a large movement in the upper part of the canal –
continue slightly towards the apex so the signal returns normal.
•An apex locator may not be able to measure in all conditions. In any case, it is
recommended to take an X-Ray prior to use of the unit and compare the information
given by both means.
•For your own safety, please wear personal protective equipments (gloves, glasses,
mask).
5. Adverse Reactions :
None known.

6. Step-by-Step Instructions
A. Content
Check the content of the equipment before use:
-one ProPex®II apex locator
-one charger
-one measurement cable
-two lip clips
-two connection hooks
-two connection forks
-one user manual
B. Recharging the Battery
The ProPex®II is delivered with a rechargeable battery.
On ProPex®II a screen indicator shows the level of the battery charge. When this is
flashing, the battery requires recharging. However, it is still functional for several
treatments before the battery shuts down.
Procedure for recharging the battery:
1. Disconnect the measurement cable
2. Connect the charger cable to the ProPex®II
3. Connect the charger to the mains
Charging screen will appear during battery charging. When the battery image on the
screen stops blinking and turns green, the charging is complete.
Low Mid Full
Duration of charging: About 12 hours (24 hours after long periods without use).
Note: ProPex®II cannot be used while charging.

C. Replacement of the rechargeable battery
The battery compartment is located at the bottom of ProPex®II and its cover is secured
by a screw.
1. Release the screw and remove the battery compartment cover
2. Remove the battery and disconnect the battery cable from the jack connector
3. Insert the new battery cable into the jack connector
4. Insert the battery into the battery compartment.
5. Close the battery compartment and secure it with the screw
Warning: Use only original battery pack from your supplier !

D. Getting Started
1. Disconnect the charger from the device if connected
2. Connect the measurement cable and switch the device On – after a short logo
presentation, the main screen is displayed and the cursor on the tooth image will
start blinking.
(While turning the device On without the measurement cable – the main screen
will be displayed without cursor on the tooth image)
3. Attach the lip clip to the patient
4. Insert the file into the canal – (to ensure precise measurements the file size
should be adjusted to the canal diameter)
5. Connect the hook to the file
The cursor on the tooth will stop blinking (accompanied by a double beep signal).
A blinking cursor and no sound signal indicates a faulty connection. Check your
connections, clean your hook connection, moisten the canal, if necessary, and start
again.
No other adjustments are necessary before starting measurement.
Note: Connection test feature is included in ProPex®II
in order to check the cables:
●Connect metal part of the connection hook
to the lip clip
●“Connection test” icon should
appear in the bottom left corner of the
display, indicating proper connection
●If no icon appears, the connection hook or
the measurement cable should be replaced

E. Searching for the Apex
1) Coronal and Medial Zone
Slowly introduce the file into the canal.
The cursor on the tooth icon indicates the progression of the file inside the canal.
Further progression of the file in the canal is shown both by the cursor on the tooth icon
and by numerical value on the graphical scale (which does not represent length in
millimeters). ProPex®II emits audible information of file progression via a series of
progressive rate beeps.

9 / 71
2) Apical Zone
The apical zone is divided into 10 segments graduated from 0.9 to 0.0 (apex) as visual
information of file progression.
When the apex is reached, the cursor shows “APEX” and a solid tone is emitted.
Beginning of Apical
Zone
Middle of Apical Zone Apical position
Once apex is reached, it is recommended to subtract 0.5 mm to determine the working
length for shaping
3) Over-instrumentation
A red segment and a warning signal indicate that the file has passed the Apex. The
cursor on the tooth icon shows “OVER”.

10 / 71
F. Sound Adjustment
ProPex®II is equipped with a sonic indicator which enables monitoring of the progression
of the file within the canal.
This function, in conjunction with the display of progression, enables working "blind" while
still monitoring the progression of the file.
The volume can be adjusted to one of four levels: mute, low, normal and high, by
successive presses on the volume key.
G. Demo mode
The built-in Demo mode is available to become acquainted with the device and to
demonstrate it’s operation.
1. Disconnect the measuring cable or the charger from the device if connected and
turn Off the device
2. To start Demo Mode, press and hold the (On/Off) button for about 2 sec. until
the second beep sounds and “Demo” indication appears in the bottom left corner
of the display
3. During Demo cycle device operating sequence is shown on the screen. Press
button to pause the simulation; press button again to resume
4. When Demo cycle is completed, it is repeated automatically until interrupted by
the operator
5. To exit Demo mode press button and hold it for about 2 sec. until a beep
sounds
Note: If measurement cable is connected to ProPex® II during Demo cycle, the
device switches automatically to normal operation mode
