Device Operation - Sendoline S5 Apex Locator Manuel De L'utilisateur

7.4. Device operation

Do not use this unit with patients who have a pacemaker, as its effect has not
been evaluated.
7.4.1. Place rubber dam prior to beginning endodontic treatment.
7.4.2. Obtain an initial radiograph and measure the distance between a reference
point (i.e. incisal edge, peak of the cusp, etc.) to the image of the anatomical
apex for the canal you will be working on. Subtract 0.5mm to establish your
TEMPORARY working length.
7.4.3. Preflare the canal to partially remove canal
contents and establish patency to your
TEMPORARY working length.
7.4.4. To ensure proper measurements, verify that
the canal is not completely dry or calcified. If
needed, fill the canal with an electrolytic
solution (i.e. Sodium Hypochlorite, Saline,
etc.).
7.4.5. Depending on the size of the canal, insert a
#15 hand K-file or other appropriate file into
the canal.
7.4.6. Press the On-Off
on the display.
7.4.7. Before connecting the measurement cable with attached lip clip and file clip
to the patient, plug measurement cable into the device receptacle and make
sure that the cable icon appears on the display (Fig. 4).
7.4.8. Put the lip clip onto the patient's lip.
7.4.9. Connect the file clip to the file. The S5 Apex Locator will automatically detect
that root canal measurement has started. If the electrical contact is good and
the conductivity of the root canal is sufficient, the file icon inside the small
tooth image will stop blinking and a double beep audio signal will sound.
If there are no beeps, stop measurements, clean the file clip and the file, irrigate
the canal, if required, and resume measurements.
Make sure that irrigation solutions, blood or saliva don't fill the access cavity.
Dry the cavity if required before performing measurements.
