Cutting debris on tooth Pulp inside canal
Thoroughly remove all cutting debris on the tooth.
Thoroughly remove all the pulp inside the canal;
otherwise an accurate measurement cannot be made.
Caries touching the gums
In this case, electrical leakage through the caries infected
area to the gums will make it impossible to obtain an
accurate measurement.
Blocked canal
The meter will not move if the canal is blocked.
Open the canal all the way to the apical constriction
to measure it.
Extremely dry canal
If the canal is extremely dry, the meter may not move
until it is quite close to the apex. In this case, try
moistening the canal with oxydol or saline.
