Cause
The mucosal electrode does not
have a sufficient contact to the oral
mucosa.
The file clamp may possibly be dirty.
The crown of the tooth is covered
with blood or chemicals which flowed
out of the canal and over the crown
and neck, thus establishing an elec-
tric contact with the gums.
The root canal is filled with blood or
electrolytic fluid.
The root canal instrument or contra-
angle handpiece is touching the
gums.

cloth moistened in alcohol.

crown.
Rinse the root canal and suck it dry.
Avoid contact or insulate the con-
tra-angle handpiece.
