Instructions for use of the apex locator:
CAUTION !
Make sure that the measured value display is stable.
Attach the mucosal electrode so that it has a good electric contact with
the patient's oral mucosa.
Make sure that the file clamp has good electrical contact with the file
(clean the clamp with alcohol beforehand if necessary). Be sure to use a
cofferdam and wear gloves in order to obtain the insulation required for
correct measurements.
The pulp chamber must be opened correctly and cleaned.
Make sure that there are no fluids (blood or electrolytic fluid) located in
the pulp chamber.
There must not be any pulp residue remaining in the root canal.
The crown of the tooth must not be covered with blood, chemicals or mill-
ing residue. They could flow over the crown and neck, thus establishing
an electric contact with the gums.
Interference with the measurement may be caused by caries, perfora-
tions, absorption, lateral canals, large connections between the canals,
pus on the apex, metal restorations or crowns and broken-off instru-
ments.
The root canals must be moistened slightly for the measurement,
e.g. with NaOCl, NaCl or chlorohexidine.
The root canal instrument (file) and the contra-angle handpiece must not
touch the oral mucosa.
