Problem
If the problem persists, please contact your supplier.
Possible Solution
Is the file touching
metal prosthesis or
filling?
Are proximal surfaces
infected with caries?
Are there external
resorption or is the
tooth fractured?
Does a broken crown
cause incorrect
measurement?
Is there a lesion at
the apex?
Is the file clip holder
broken or dirty?
17
Touching a metal prosthesis of
filling with the file may create a
conductive path outside the canal
and cause incorrect
measurements ("OVER"
indication, unstable readings, etc.)
Deep caries may create a
conductive path outside the canal
and cause incorrect
measurements ("OVER"
indication, unstable readings, etc.)
The canal length indicator may
jump to "OVER" position when it
reaches a resorption area or a
fractured root tooth.
Build up an insulating barrier to
isolate the file from the crown.
A chronic lesion can destroy the
apical foramen through resorption
and cause incorrect
measurements.
Replace or clean the file clip.
