6. THE FUNDAMENTAL OPERATING
INSTRUCTIONS OF THE APEXLOCATOR
For more accurate apexlocator measurement results, please,
follow these rules:
1. Carefully isolate the studied tooth and working file from saliva.
We recommend to use cofferdam, cotton swabs, saliva ejectors;
2. Work only in rubber gloves;
3. Use the file, corresponding to the root canal width in the apical area
(usually ISO 10-20);
4. Do not use unclean or oxygenized files;
5. Use electroconductive gel for root canals (e.g. RC-Prep,
С anal +)
(recommended);
6. Prevent any contact of an instrument with metals in oral cavity
(amalgam restorations, crowns, brackets etc.);
7. Do not touch the working file metallic parts and patient’s mucosa
with wet hands;
8. Provide wet contact of lip clip electrode with cavity.
Attention!!! There is a possibility of measurements accuracy fall-off
in the following cases:
1. Root canal with large apical constriction
Root canal that has exceptionally
large apical constriction due to a
lesion or incomplete development
cannot be accurately measured; the
measurement results will be less than
the actual length.
