apex length determination and therefore to an under or over
instrumentation with risk of injury for the patient.
● The different file systems require different working techniques. For
this reason, please always observe the information provided by the
file manufacturer.
● Work without exerting any pressure on the file.
● The ApexLocator function of VDW 6:1 is used to support the root
canal preparation processwhen used in combination with a
treatment center with the apex length determination function. With
the VDW 6:1 the number of X-rays taken and the exposure to X-rays
to the patient and to the operator can be decreased. However, you
must always take at least one X-ray to determine the length for
preparatory work. A clinical evaluation including knowledge of the
anatomy of root canals is important for interpreting the results.
● When performing the Apex length determination, wear appropriate
insulated gloves. We recommend performing the treatment with a
cofferdam, while using a silicon sleeve. This will prevent inaccurate
length determination caused by undesired leakage currents. Avoid
the contact of the instrument with the patient's mucosa, metallic
tooth restorations, or the mucosal electrode.
!
● If the limit torque is exceeded, a gentle creaking may be heard and
vibrations felt. Remove the file by gently pulling it toward the coronal
end. If this is not possible, switch the drive into the opposite rotation
direction and pull the file out of the channel.
IMPORTANT: Check the file afterwards for damage or deformation
(untwisting) and replace it, when necessary.
