Problem
6
Indication of file
position is not steady
during the procedure.
7
The device does not
show file progression
inside the canal.
Possible cause
1. There is not a good
contact between the lip
clip and the oral mucosa.
2. The connection hook is
soiled.
3. Deep caries provides a
conductive path outside
the canal.
4. Perforation
5. Large lateral canal.
1. Bad electrical contact.
2. The connection hook is
not properly connected
to the file.
3. The root canal is
obliterated.
4. In the case of re-
treatment: old filling
material residues may
block the root canal.
Solution
1. Ensure a good contact
between the mucosa
and lip clip (Place the lip
clip in the labial angle
opposite the tooth to be
treated).
2. Clean the connection
hook (with Ethanol).
3. Block the external
conductive path.
4. Remove the file, close
the perforation and
repeat the apex
detection procedure,
carefully inserting the
file into canal.
5. Try continuing the
procedure by gently
advancing the file.
1. Perform the cable
connection test as
described in the User
Manual.
2. Place the connection
hook on the metal part
of the file below the
plastic handle.
3. Check the comparative
X-ray image for hints.
