Comparison of electronic length determination versus radiography:
X-ray radiography represents two-dimensional projection of three-dimensional root canal system.
There are some cases when the radiographic length and the electronic length do not match.
In the case of a lateral canal curvature the x-ray
may show a shorter working length than with
Apica Pro. Electronic length determined using
Apica Pro is usually more accurate than the
radiographic length.
3.7 CHECK Mode
This built-in CHECK feature enables to test automatically the basic function of
the device in a first step, followed by the test of its accessories in a second step
using the dedicated tester (Fig. 26).
To profit from the CHECK feature, follow the next steps:
• Disconnect the measuring cable/adaptor from the device.
• Device CHECK will start automatically if the tester inserted in the device and
the results will be shown on the screen (Fig. 27)
• Either OK (Fig. 28) to indicate that the device fully operates
• ERROR (Fig. 29) to indicate any malfunction.
