FOR DENTAL USE ONLY
DIRECTIONS FOR USE
Introduction
Congratulations on the purchase of ProPex®II.
ProPex®II is a device aimed at detecting the minor apical foramen based on analysis
of electrical properties of different tissues inside the root canal system. For optimal
safety and performance, read this user manual carefully before use. Make sure you
have understood and followed the clinical precautions - as well as the general
warnings, precautions and contraindications - before proceeding to determining a
working length.
Keep this user manual for future reference.
1. Indications for use
ProPex®II is an electronic device used to indicate the location of the apex and the
working length. This product must only be used in hospital environments, clinics or
dental offices, by qualified practitioners.

6 / 120
2. Contraindications
The ProPex®II is not recommended for use:
in patients who have a pacemaker or other implanted electrical devices, or have
been cautioned by their physicians against the use of small electric appliances
such as shavers, hair dryers, etc,
in patients allergic to metals,
in children.
3. Warnings
The scale indication on the ProPex®II screen does not represent a distinct length
or distance in mm or other linear units. It simply indicates the file progression
towards the apex.
The following patient's related factors may prevent accurate readings:
-Blocked root canals,
-Teeth with large apices,
-Root fracture or perforation,
-Metal crowns or bridges, if they come into contact with the file or the lip clip.
Inaccurate or incorrect readings due to the environment are likely to occur in the
following cases:
-Presence of portable or movable radio frequency transmitters in the
surroundings.
-Film viewers or other Illumination devices which use an inverter may cause
abnormal operation of the apex locator. Such devices should be turned off
during use of the ProPex®II.
Electromagnetic interference could cause improper operation of the device. In
such cases the device behavior may become abnormal or random. Usage of any
devices emitting electromagnetic radiation, such as cellular phones, remote
controls, transceivers, etc., should be prohibited in the vicinity of ProPex®II.
General safety warnings:
-In order to prevent infectious agent transfer it is highly recommended to use a
rubber dam system during the endodontic procedure.
-Make sure that the lip clip, hook or fork does not come into contact with an
electric power source such as an electrical socket. This could result in a
severe electrical shock.
-Do not use ProPex®II in the presence of flammable substances.
Only use the original battery pack from your supplier.
Only use the original charger.

4. Precautions
Important notice
The use of apex locators alone without a preoperative and postoperative radiograph
is not a recommended practice, since apex locators may not be able to work properly
in all conditions.
It is mandatory to confirm radiographically the working length established using the
apex locator.
It is important to follow the precautions below and pay close attention to any condition
or situation that may influence the electrical conductivity during the procedure.
Inaccurate or incorrect readings are likely to occur in the following cases, all
procedure related:
-Partially blocked canal.
-Size of the measuring file differing significantly from the canal diameter. Ideally,
the selected file should be the thickest one capable of reaching the apex.
-Presence of liquids and/or tissue debris in the access cavity. Prior to the use of
the device, the access cavity must be dried with a cotton pellet in order to
prevent leaking current.
-Contact of the file or the lip clip with metallic dental structures. Be particularly
careful with patients fitted with metal crowns or bridges.
-Contact of the file with another instrument.
-Very dry canal, for instance in the presence of restoration. In this case the canal
must be moistened with an irrigation solution, or with GlydeTM file prep.
-Contact between the file and the gums (this may cause a false reading indicating
that the apex has been reached).
-Use of an ultrasonic scaler with the counter electrode attached to the patient
(electrical noise from the scaler could interfere with the apex localization).
-Use of the apex locator in conjunction with an electric scalpel.
-Use of a damaged lip clip, hook or fork.
For apex localization, concentrations of NaOCl higher than 5 % may result in
reduced accuracy.

8 / 120
As a safety precaution in order to avoid over-instrumentation, it is recommended
to proceed as follows: place the file onto an endodontic ruler at the point where
the ProPex®II indicates ‘APEX’. Subtract a minimum of 0.5 mm from the
measured file length.
Please also respect the following precautions:
-For your own safety, be aware of wearing personal protective equipment
(gloves, glasses, mask).
-If the bar graph makes sudden large movements in the coronal part of the canal,
slowly continue advancing the file toward the apex until the signal returns to
normal.
-This ProPex®II unit must not be connected to or used in combination with any
other apparatus or system. It must not be used as an integral component of any
other apparatus or system. Using replacement parts or accessories not supplied
by the original manufacturer or vender could adversely affect the EMC
performance of the ProPex®II.
-The device must be used with the manufacturer's original accessories only.
-Unplug the device before replacing the battery.
-Never use batteries that are leaky, deformed, discolored or otherwise abnormal.
-In case of battery leakage, carefully dry the battery terminals and remove all of
the leaked liquid. Then replace the battery with a new one.
-If you do not use the device for a long period of time, it is recommended to
remove the battery from the device to prevent possible fluid leakage.
-Dispose of old batteries according to local codes and regulations.
-Accessories including lip clips, hooks or forks should be clean and without
residue of chemical disinfectants or other medicinal solutions such as sodium
hypochlorite or formalin.
-Do not expose ProPex®II to any liquid.
-ProPex®II must be stored in normal temperature (< 60°C) and humidity
conditions.
5. Adverse Reactions
If the apex locator provides incorrect reading and there is no radiographic data (see
"Important notice" in the “Precautions” section in chapter 4), the following adverse
reactions may occur:
Incomplete root canal treatment,
Apex perforation.

E. 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

F. 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. ProPex®II emits audible
information of file progression via a series of progressive rate beeps. If the bar graph
makes sudden large movements in the upper part of the canal, continue slightly
towards the apex so the signal returns to normal.
Warning: The scale indication on the ProPex®II screen does not represent a distinct
length or distance in mm or other linear units. It simply indicates the file
progression towards the apex.

14 / 120
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
Note: As a safety precaution in order to avoid over-instrumentation, it is
recommended to proceed as follows: place the fill onto an endodontic ruler at
the point where the ProPex®II indicates ‘APEX’. Subtract a minimum of 0.5
mm from the measured file length.
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”.

15 / 120
G. 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.
