Blocked canal
The meter will not run if the canal is
blocked. Opening the canal all the way
to the apical construction to measure it.
Extremely dry canal
If the canal is extremely dry, the meter
may not work until it is quite close to
the apex. In this case, try to moisten
the canal with oxydol or saline.
Difference measuring result between Apex locator reading and Radiography
Sometimes the reading of the apex locator reading does not correspond to the X-
ray image. this does not mean inaccurate of apex locator or X-ray, depending on
the angle of the X-ray beam, the root tip may not be displayed correctly. The
position of the root tip seems to differ from its true position.
The X-ray photo shows that the actual
apex of the root canal is not the same as
the anatomic end. In fact, the apical
foramen is located at the coronal end. in
this case, X-ray may indicate that the file
needle has not reached the apical
foramen, even if it has actually reached
the apical foramen.
