Root canal with blood overfl owing from the opening.
If blood overfl ows 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 throughly to get rid
of all blood, and then make a measurement. Root canal
with a chemical solution overfl owing from the opening.
An accurate measurement cannot be obtained if some
chemical solution is overfl owing from the canal
opening.
In this case, clean the canal and its opening. It is
important to get rid of any solution overfl owing the
opening.
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
fi le 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.
Fractured tooth.
Leakage through a branch canal Fractured tooth will
cause electrical leakage and an accurate measurement
cannot be obtained. A branch canal will also cause
electrical leakage.
Re-treatment of a root fi lled with gutta- percha. The
gutta-percha must be completely removed to eliminate
its insulating eff ect. After removing the gutta-percha,
pass a small fi le all the way through the apical foramen
and then put a little saline in the canal, but do not let it
overfl ow the canal opening.
Crown or metal prosthesis touching gingival tissue.
Accurate measurement cannot be obtained if the fi le
touches a metal prosthesis that is touching gingival
tissue. In this case, widen the opening at the top of the
crown so that the fi le will not touch the metal prosthesis
before taking a measurement.
