Precautions

4 Precautions
Important notice:
The use of apex locators alone without a preoperative and
postoperative radiograph is not a recommended practice, since apex
locators may not be able to work properly in all conditions.
It is mandatory to confirm radiographically the working length
established using the apex locator.
It is important to follow the precautions below and pay close attention to
any condition or situation that may influence the electrical conductivity
during the procedure.
• Inaccurate or incorrect readings are likely to occur in the following
cases, all procedure related:
- Partially blocked canal.
- Size of the measuring file differing significantly from the canal
diameter. Ideally, the selected file should be the thickest one
capable of reaching the apex.
- Presence of liquids and/or tissue debris in the access cavity. Prior
to the use of the device, the access cavity must be dried with a
cotton pellet in order to prevent leaking current.
- Contact of the file or the lip clip with metallic dental structures. Be
particularly careful with patients fitted with metal crowns or
bridges.
- Contact of the file with another instrument.
- Very dry canal, for instance in the presence of restoration. In this
case the canal must be moistened with an irrigation solution, or
with Glyde™ file prep.
