Fig. 1
As the root canal file is inserted, the measurement bar on the screen lights
up from top to bottom.
When displayed as shown in figure 1, the value of the reference range is
2, indicating that the distance from the tip of the tooth root is about 2mm
at this time. At the same time, the APEX locator emits a "di" alarm sound
at a long interval.
When displayed as shown in figure 2,it means that the distance from
the tip of the tooth root is close, about 1.5 mm, and the time interval of
"di~di~" alarm sound emitted by the APEX locator becomes shorter.
Fig. 2 When displayed as shown inf igure 3,it means that it reaches the tip of
the tooth root. The measured value is 00, which is the actual length of the
root canal to be measured.
When displayed as shown in figure 4,it means that the root canal file has
gone beyond the tip of the tooth, and the main body emits a very urgent
"di~~" alarm sound.
The tip of the tooth root position (measured value: 00) measured by this
Fig. 3
device is the Major/Anatomic apical foramen. In clinical practice, in order
to prevent surgical failure caused by piercing the root apical orifice, 0.5-
1.0 mm is usually taken from the measured value, which is the Minor/
Physiological apical foramen prepared for root canal.
The value of the reference distance is only an estimated value, not a
clinical basis.
The measured value does not represent the distance, only the trend of
gradual entry.

During measuring, enter slowly to prevent piercing the tip of the root.
The APEX locator is used to determine the working length of the root
canal. In clinical use, it must be combined with X-ray and other means to
determine the working length of the root canal.
The device should be used by dentists with knowledge of dental root
canal length and skill in operation.
