Tips for
SuccessfulLength measurement
Condition
of
inaccurate measurement
Too fast
movement
or even
jumping
to the apex
directly
is
indicated
for
the
following reasons:
Too slow or
extremely delayed movement
is
indicated
for the
following reasons:
Obliterated
root canal
Impeding the
conductive
path and
preventing
normal
device
functioning.
•
Compared with X-rays, find
possible
clues.
•
Catheterize with ISO 06/ 08 file till
the
working
length.
Retreatment: Blockage
by old
canal
filling
materialresidue, impeding
the
conductive
path and
preventing
normal
device functioning.
Take an x-ray to
re-check
and try
to
completely
remove the old root
canal
filling
materialbefore measurement.
Blockage
by
remnants
of a
medicated
substance
(e.g.
calcium hydroxide)
impeding
the
conductive
path
and
preventing
the
normal operation of
the
device.
Remove
the
remnants
Completely
before measurement.
