6. THE FUNDAMENTAL OPERATING
INSTRUCTIONS OF THE APEXLOCATOR
For more accurate apexlocator measurement results, please,
follow these rules:
1. Carefully isolate the studied tooth and working file from saliva.
We recommend to use cofferdam, cotton swabs, saliva ejectors;
2. Work only in rubber gloves;
3. Use the file, corresponding to the root canal width in the apical area
(usually ISO 10-20);
4. Do not use unclean or oxygenized files;
5. Use electroconductive gel for root canals (e.g. RC-Prep, Сanal +)
(recommended);
6. Prevent any contact of an instrument with metals in oral cavity
(amalgam restorations, crowns, brackets etc.);
7. Do not touch the working file metallic parts and patient’s mucosa
with wet hands;
8. Provide wet contact of lip clip electrode with cavity.
Attention!!! There is a possibility of measurements accuracy fall-off
in the following cases:
1. Root canal with large apical constriction 
Root canal that has exceptionally
large apical constriction due to a
lesion or incomplete development
cannot be accurately measured; the
measurement results will be less than
the actual length.
Fig.4

ENDOEST-3D
hotline @ geosoft.ru
2. Root canal with blood, saliva or a chemical solution overflowing
from the opening
If blood, saliva, or a chemical
solution overflows from the opening
of the root canal and contacts gums,
this will result in electrical leakage
and an accurate measurement can
not be obtained. Wait for bleeding to
stop completely. Clean the inside and
opening of the canal thoroughly to
get rid of all blood, saliva and
chemical solutions and then make a measurement.
3. Broken crown
If the crown is broken and a section
of the gingival tissue intrudes into the
cavity surrounding the canal opening,
contact between the gingival tissue
and the file will result in electrical
leakage and an accurate
measurement cannot be obtained. In
this case, build up the tooth with a
suitable material to insulate the gingival tissue.
4. Fractured tooth. Leakage through a branch canal
Fractured tooth will cause electrical
leakage and an accurate
measurement cannot be obtained.
A branch canal will also cause
electrical leakage.
Fig.5
Fig.6
Fig.7

USER’S GUIDE
www.geosoft.ru/en
5. Retreatment of a root canal, filled with gutta-percha
The gutta-percha must be completely
removed to eliminate its insulating
effect. After removing the gutta-
percha, pass a small file all the way
through apical constriction and then
put a little saline in the canal, but do
not let it overflow the canal opening.
6. Crown or metal prosthesis touching gingival tissue
Accurate measurement cannot be
obtained if the file touches a metal
prosthesis that is touching gingival
tissue. In this case, widen the opening
at the top of the crown so that the file
will not touch the metal prosthesis
before taking a measurement.
7. Cutting debris on tooth. Pulp inside canal
Thoroughly remove all cutting debris
on the tooth. Thoroughly remove all
the pulp inside the canal.
Otherwise an accurate measurement
cannot be obtained.

8. Caries contacts with gum
In this case, electrical leakage
through the caries infected area to
the gums will make it impossible to
obtain an accurate measurement.
9. Blocked canal
The meter will not move if the canal
is blocked. Open the canal all the way
to the apical constriction to measure
it.
10. Extremely dry canal
If the canal is extremely dry, the
meter will not move until it is quite
close to the apex. In this case, try to
moisten a canal with saline.

7. MAKEREADY AND USING
After the device transportation at temperature below +5 С, you
should let it warm up for an hour at room temperature before
switching it on.
7.1. Accumulator charging
Chargeable Li-Po accumulator battery is the “EndoEst-3D” source
power. Before the first device use it is necessary to fully charge the
accumulator.
One may charge the accumulator from the mains (110-240)V or from
the PC USB-port.
The accumulator should be charged in the following way:
- Connect the cable for accumulator charging (6-fig.1) to the device
“EndoEst-3D”. Insert the USB (B) cable plug to the «APEX/
CHARGE” socket (7-fig.2) on the device.
Variant 1. Charging from the
mains:
- Connect the open plug of the
cable for the accumulator
charging to the USB socket of the
charger (7-fig.1) - see fig.14 and
insert the charger into the
standard mains supply socket
(110-240)V.
Variant 2. Charging from the USB-port:
Рис.14

17
ENDOEST-3D
hotline @ geosoft.ru
- Connect the open plug of the cable for the accumulator charging to
the PC USB-port .
Yellow light (8-fig.2) indicates that accumulator is being charged.
When the accumulator is fully charged, indicator goes down (slight
lightning is possible).
Note: Standard time for the accumulator charging is about 2,5 hours,
however, it depends on the accumulator current charge, level of its
wear, temperature.
Operation and charge time of the old accumulator is shorter than of a
new one. In the case of meaningful reduction of the device operation
duration you should address to the service department to replace the
old accumulator for a new one.
- Remove the charger plug from the mains socket and disconnect the
cable from the device and PC when the device is charged.
7.2 Indication of the accumulator discharge
When the accumulator charge is lower than minimally allowable
level (<20%), warning “LB” indicator (7-fig.3) appears on the device
display.
Having seen such an indicator, charge the accumulator according to
the p.7.1.
Otherwise, when the accumulator charge falls to the critic level
(<10%), the device switches off automatically.
Attention! When discharged, charge the device power supply in time.
Exclude the accumulator full discharge.

7.3. Power saving function
To increase time between the accumulator charging and to extend the
device life time, the device has power saving function - automatic
switch off in 40 minutes after the last time of device use at the absence
of use.
7.4. Connecting the cable and electrodes
- Connect the cable “Signal Line” (2-fig.1) to the device “EndoEst-
3D”. Insert the USB (B) cable plug to the «APEX/CHARGE” socket
(7-fig.2) on the device.
Note: For ensuring
the maximum usability
of the device in the
process, as well as to
prevent breakage of the
working cable it is
possible to output a
working cable on the
front side of the device.
To do it you need:
- to disconnect a
cable from the
control unit
- to place a wire of
a working cable in
the rubber sleeve (fig. 15) ;
- to connect a cable to the device

USER’S GUIDE
www.geosoft.ru/en
where: APEX - Apexlocator mode;
EOD - Electro-odonto-diagnostic mode ;
PULP - Dentometer mode
Note: The operation mode you used the last time, before the device
switching off or entering the power saving mode, will automatically
start when reusing the device.
7.6. Checking of circuit continuity of the device
Before starting to work be sure to check the working circuit continuity
“control unit - cable - probe - lip clip”. 
You can check the working circuit continuity when the device is ready
for work in the APEX or PULP mode by closing the passive and
active electrodes against each other.
At this moment LED indicator (3-fig.2) has to light RED color and a
continuous sound signal appears.
If the lighting of indicator doesn’t appear or it is flashing on and off
this means that the circuit continuity is broken and the device is out of
service. In this case, you should replace the cable (rarely, file clip) or
address the service department.
7.7. Operating in the APEX mode
Attention! Before starting to work in the APEX mode, you should
thoroughly read the fundamental operating instructions for the
apexlocator considered in the part 6 of the User’s guide.
1. Switch on the device APEX mode (see p.7.5)
