Asepsis
Aseptic conditions are established when the access cavity is
complete the area is dry and there is no leakage around the
rubberdam. Sodium hypochlorite is used to rinse and irrigate the
area

Once the working length is determined the canal is cleaned and
shaped in a
crown down (crown to apex) direction. There is specific
instrumentation foraccomplishing each stage of cleaning and shaping
.
The canal can divided into coronal middle and apical thirds for
this purpose.

If time or situation (necrotic tissue) does not allow a calcium
hydroxide
paste is placed in the canal as an dressing between
appointments. In
the clinic at ASDOH we will utilize a product called metapaste
which is
gently syringed into the canalsThe coronal access is the sealed
using a temporary zoe paste. It is highly
important to insure that there are no chances of coronal
leakage.

Fitting and Seating the Master Cone
A sized gutta percha cone( to the master apical
file size) is fitted within 1 mm of the workinglength. It should
be sug and have a slight
resistance to removal. Radiographic examination
should show it to be no more than one mm short
of the working length

Canal Obturation using vertically
compacted Warm Gutta Percha
The master cone is seated with sealer
and the coronal segment is removedwith heat and in a series of
warming
and condensing stages the canal is
obturated to the apical 1/3 and
backfilled to seal the canal.
