TROUBLESHOOTING (Continued):
k. The canal may be extremely dry, moisten the canal with
water or sodium hypochlorite.
l. The canal may be exiting at a sharp angle. Sometimes the
file is not able to follow a sharp bend and the file cannot
be inserted any further.
9. The display indicates perforation right away or provides
imprecise, erratic or short indications.
a. Verify the pulp chamber is clean and dry.
b. The canal maybe filled with blood or electrolytic fluids. In
this case, the meter sometimes jumps when the file tip
breaks the surface of the fluid. The display will return to
normal as the file approaches the apex.
c. The tooth maybe covered with cutting debris or chemi-
cals. Clean off the surface of the tooth if so.
d. The file may be making contact with the gums or other soft
tissue in the mouth. This will cause inaccurate readings.
e. Too much pulp may be left in the canal. Sometimes a
large amount of pulp in the canal can interfere with accu-
rate readings.
f. Amalgam restorations or crowns may cause the unit to
overreact if the restoration is in contact with the file probe.
If this is the case, move the file out of contact with the
metal restoration.
g. Caries on proximal surfaces can cause inaccurate readings.
h. If a lateral canal is present, the unit may indicate apex at
the branch canal.
i. If the crown has been lowered by removal of the occlusal
surface, the possibility of electrical contact with the gums
is increased. Wash the canal with sodium hypochlorite in
this case.
j. Verify the file clip metal is clean, free of debris and corro-
sion, clean if not.
k. The unit often overreacts if the canal has an exceptionally
large foramen and is filled with an electrolytic solution.
The unit should return to normal display as the file
advances toward the apex.
l. If the unit still overreacts near the apex, dry some of the
electrolytic solution and use a larger file closer to the size
of the apex.
