integrated. The position of the mark should be on the incisal edge of the anterior
tooth or on the spire of the molars. For those bridge that's broken obviously, this
symbol should be on the tooth surface supported by the dentin instead of on the
suspended enamel.
4.1.7 The acute inflammation surrounding the apex has been gone and the infected
material has been cleaned. It is also necessary to get rid of the pulp and necrosis
tissue.
4.1.8 The following cases are not suited for a normal measurement:
a) The size of the root similar to the size of apical foramen.
In this case, the measurement result of the length of the root canal will be shorter
than its real because of the hypoplasia of the root [Picture 8].
b) Bleeding or the blood overflow from the apical foramen.
In this case, the blood will overflow from the root canal and reaches gingival that the
blood and the gingival will be on a conducting state which will cause an inaccurate
result while measuring. The measurement can be continued when the bleeding is
stopped [Picture 9].
c) The tooth crown is broken.
The tissue of the gingival may reach the cavity of the endo hole at the broken point
which will cause inaccuracy because of the electronic conduction. The measurement
can be continued when the crown is fixed by gypsum or other insulators [Picture 10].
