(Fig 20D)
The dentist was asked to take this as a learning

opportunity and strictly follow the philosophy of
Schilderian Endodontics. Upon examination of the

pre-operative radiograph, a widened PDL can be seen

#
at the disto-apical of tooth 22. The canal is likely not
completely calcified at the apex with the canal exiting

slightly towards the distal. (See “Working Length”)

(Fig 20E)

With adequate instrumentation of the coronal and
middle third of the canal, a small file will then slide

down smoothly to the radiographic terminus. The
canal exit can be seen located slightly towards the
distal; the file is positioned in the centre of the canal
following the natural curvature of the root.

(Fig 20F)

The master apical file is situated at the centre of the
canal following the same curvature as the smaller file

in “Fig 20E”. This shows that the apex has not been
transported after cleaning and shaping of the canal.
