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.
Clean
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 from the
opening.
