4.2 Integrated Apex Locator
iRoot pro is equipped with an integrated apex locator.
WARNING:
Combined apical length measurement by using the contra angle and lip clip give only accurate
results when using the original contra angle by manufacturer supplied.
Use only endodontic NiTi files with a metal handle for this type of root canal measurement.
In some clinical cases accurate root canal measurement is impossible! ( for details see chapter
9 “Troubleshooting”)
Electric root canal measurement uses minimal auxiliary current. The values used in the device
are far below the values required in IEC 60601-1. Nevertheless, in rare cases electrical
sensation during the apical length measurement can occur. In this case, do not continue the
treatment with this patient.
4.2.1 Four working mode
There are four types of working mode related to Endo motor an Apex Locator.
Mode, Apex locator control motor how to rotate.

15
Mode, Apex locator is working independently, and endo motor is invalid.
Mode, Independent Endo motor, Apex locator is invalid.
Mode, Apex locator and motor work separately.
To short press “S” key to enter the working mode option, to select working mode in the select
box by “+/-”key, when the machine is on.
NOTICE:
In working mode, motor and apex locator will work at same time, but both work
independently without control to each other. When reach apical, the apex locator only indicate
the apical length, will not control motor to switch to anti-clockwise rotation and reverse out.
In working mode, motor and apex locator will work at same time, apex locator will control
the preparation of motor. Endo motor will auto start, auto reverse out
according to the root canal measurement of the apex locator.
4.2.2 Useful tips for accurate length determination
Gloves and rubber dam are recommended in order to isolate the tooth.
Dry the access cavity with the suction pump or a cotton-pellet.
Avoid any direct contact between the contra angle file and mucosa. Use the silicone sleeve for
the contra angle.
4.2.3 Optional Apical Line
This feature is convenient for users to make marks of the
relative distance from apical point;
The range of markers is from 15 to 27;
According to user labeled apical scale, when reaching marker
position, better visual and sound cues.
Complete following steps to change the marks of apical point
Long press “S” to enter other operation mode, keep short press “S” until it indicates apex
locator working length bar, to adjust by “+/-” key.
NOTICE:
Settings will be saved automatically
This mark for the apical is available in all working mode including QS mode and apex locator
control motor working mode once set.
Set the apical line from 15 to 27

Combined apical length
measurement
4.2.4 Operation of Apex Locator
We are committed to producing safe and reliable medical equipment to let doctors handier to use, so we
recommend doctors to use the apex locator control motor mode.
4.2.4.1 Connecting
For combined apical length measurement use the contra angle, covered by the silicone sleeve.
Connect the lip clip cable to the Micro USB port at bottom of the central unit. Insert the lip clip
into the connector at the end of the cable. Ensure the connection is solid.
Put the pip clip in the patient’s mouth (we recommend positioning it on the opposite side of the
tooth undergoing therapy).
For independent apex locator measurement use the separate file clamp with a manual measuring file
instead of the contra angle.
Connect the Measuring cable for apex locator to the Micro USB port at bottom of the central
unit. Insert the lip clip into one of the connectors, insert the file clamp into another connector.
And ensure both the connection is solid.
Put the lip clip in the patient’s mouth ( on the opposite side of the tooth undergoing therapy)
4.2.4.2 Measuring loop detection
A. For combined apical length measurement （Insert a Measuring cable
B，Contact with the lip clip and file，select the Apex locator
control motor rotation mode）
Contact the file installed on the Contra angle with the lip hook will cause
the following conditions：
1) File will anti-clockwise rotate
2) The warning will sound rapidly
3) Display on the screen：Root canal indicator scale full grid, the root canal indicator data: “- -”, APEX
non-stop flashing
At this time, it is proved that the measuring circuit is normal, and the next operation can be carried out
Independent apex locator measurement
Combined apical length measurement

17
Independent apex locator
measurement
B. For Independent apex locator(insert a
Measuring cable A and select the Independent endo motor mode)
Contact with the lip clip and file clamp will cause the following conditions：
1) The warning will sound rapidly
2) Display on the screen: Root canal indicator scale full grid, the root canal
indicator data: “- -”, APEX non-stop flashing
If the above-mentioned problems are not present, the reason for abnormal loop may be as follows:
One cable may be broken or in bad contact
The connecting of the cable is not good
The contact between lip hook and file climp or the lip hook and file is too short
The file is in poor conductivity
4.2.4.3 Application steps
Operation: After setting above parameters, connecting measuring cable, detecting measurement
loop, hand the lip hook on the patient’ s lip, the treatment can be started
The response of motor:
1）Putting the file into the root canal, the file will self-acting rotate as setting speed, torque. Or press
ON/OFF to drive the file to rotate
2）When the file approaching the apical foramen, the motor will automatically slow down, when
reaching the apical foramen, the motor will auto reverse.

Response of alarm：
With the file depth, alarm sound from slow to fast, to APEX, the alarm sound becomes constant, over
APEX the alarm sound rapidly changes
Screen display：
With the file depth, the root canal relative value will change to the apical/APEX appears, Root canal scale
is full, the root canal relative value is “00”; over apical, APEX flashing, Root canal scale is full, the root
canal relative value is “- -”.
4.3 Rotation and settings in different modes
4.3.1
Rotation in different modes
Forward: Rotation is in clockwise motion.
When the load is beyond the set torque limit or reach the apical, it will automatically reverse out,
when the load is removed, it will start normal rotation again.
Reverse: Rotation is in Anti-clockwise Motion.
I
n the general condition, when the Endo Motor Rotate in counter- clockwise motion will be claim as
reverse motion. The traditional rotary files are drawing from the canal by reverse motion. Therefore,
beep sound will occur when using this function.
Load lower than the set
torque limit value
Reverse rotation when load continues or
reach the apical, stop and return to clockwise
rotation when load is removed.
Load higher than the set
torque limit value,
anti-clockwise
Anti-Clockwise Rotation
