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.
