Unsuitable situation of root canals for Electric Measurement
Cannot obtain precise measurements if the root canal conditions as below
Root canal with a large apical
foramen
The root canal cannot be accurately
measured because of the lesion or
incomplete development of the apical
foramen. The results may show that the
length measured is shorter than the
actual one.
Root canal blood overflow from the
opening
If blood spills from the root opening and
contacts the gums, it will cause leakage
of electricity, which cannot be accurately
measured. Wait for the bleeding to stop
completely. Clean the root canal and the
opening, completely empty the root
canal blood, and then measure it.
The root canal uses a chemical
solution to flow out from the opening
If a chemical solution flows out of the
root canal, it is impossible to get an
accurate measurement.
It is important to remove the overflow
