Cause
There is still some pulp residue in the
root canal.
The current could flow across a
metal denture.

proximal surface infected with caries.
Pus may be located on the apex.
This can make measurement impos-
sible.
It may be necessary to dry the inte-
rior of the root canal.
The file clamp or the cables of the
clamp or the mucosal electrode are
defective.
The apex is larger than 0.4 mm.
Incomplete apex.
Renewed treatment of the root canal
with silver filling tips.
Presence of large lateral canals or
larger branchings between the
canals.
The root canal may e.g. be blocked
by lime deposits or dentine chips.
Broken file tip in the root canal.
