7 Operation
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.
Build-up (e.g. cement)
Broken crown
If the crown is broken, a segment of the
gingival tissue enters the lumen, and the
contact between the gingival tissue and
the root file causes electrical leakage,
which cannot be accurately measured.
In this case, the appropriate material
should be used to isolate the gingival
tissue.
Branch
Crack
The crack tooth Leakage through
branch of the root canal
Broken teeth can cause electrical
leakage and cannot be accurately
measured.
Branch tubes can also cause leakage.
