Accurate measurement cannot be obtained with the root canal conditions shown below.
There may be cases other than these where an accurate measurement cannot be made.
3. Root canals not suitable for electronic measurement
Root canal with a large apical foramen
Root canal that has an exceptionally large apical foramen
due to a lesion or incomplete development cannot be
accurately measured; the results will show shorter
measurement than the actual length.
Root canal with blood, saliva or a chemical
solution overflowing from the opening
If blood, saliva, or a chemical solution overflows from the
opening of the root canal and contacts the gums, this will
result in electrical leakage and an accurate measurement
cannot be obtained. Wait for bleeding to stop completely.
Clean the inside and opening of the canal thoroughly to
get rid of all blood, saliva and chemical solutions and
then make a measurement.
Broken crown
If the crown is broken and a section of the gingival tissue
intrudes into the cavity surrounding the canal opening,
contact between the gingival tissue and the file will result
in electrical leakage and an accurate measurement cannot
be obtained. In this case, build up the tooth with a suitable
material to insulate the gingival tissue.
