How do I read
As long as the file moves in the
coronal and medial section of the root canal, its position is only shown in the
full tooth image (upper left in the display).
As soon as the file moves towards
the apical region, the position of the file is additionally shown on the
enlarged image in the APEX ZOOM (right in the display).
Blue bars (see Fig. 1): the file is
approaching the working length position.
Green to yellow bars (see Fig. 2 and
3) correspond to the section of the apical
constriction up to the apical foramen, i.e. this is the relevant region for determining
the working length.
Red bar (see Fig. 4): the file tip
has reached the apical foramen.
Red warning dot (see Fig. 5): the
apical foramen has already been exceeded (CAUTION! Overinstrumentation).
The working length should usually be
determined at the third green bar (see Fig. 2). Since the working length must
always be specified in consideration of the respective pathological situation
(vital or devital) and in accordance with the personal decision, the working
length may however vary between the first green and last yellow bars. You can
find detailed information in the RAYPEX 6Operating Manual, Chapter 7.5.
Determining the working length can
be done both in the customary rinsing solutions as well as in the physiological
milieu. Since the rinsing solution used has a small influence on determining
the working length, we recommend:
a) to determine the length in a
moist, physiological milieu and/or
b) to determine the length in a physiological saline solution 0.9% NaCl or low
percentage sodium hypochlorite solutions (e.g. 2% NaOCl)
After electric length determination
and setting the stopper, the metric working (in mm) length should be determined
with the help of a measuring gauge (e.g. VDW Minifix measuring gauge).
