'The historical sense involves
a perception, not only of the pastness
of the past, but of its presence.'
- T.S. Eliot, 'Four Quartets'

Introduction
Studies assessing the diametric dimensions
of apical anatomy repeatedly demonstrate
that the buccolingual diameter is greater
than the mesiodistal diameter-canals
are predominantly ovoid throughout, not
round1-4 (Figs. 1a and 1b).
The technical flaw most inherent-the
use of a round file of any design to clean an
ovoid canal configuration-manifests as the
failure to debride a substantial amount of
the canal contents. A recent study showed
that the mean (± standard deviation) of
untreated areas ranged from 59.6 percent
(±14.9, group PT/2) to 79.9 percent (±10.3,
PT/1) for the total canal length and 65.2
percent to 74.7 percent for the apical canal
portion, respectively5 (Fig. 2).
In the 1960s, Dr Herbert B. Schilder
introduced two legacy concepts to the science

Fig. 1a. This axial view of a mandibular molar
demonstrates the ovoid eccentricity of the canals
and the existence of an isthmus connection
between the MB and ML canals consistent with
the findings of numerous studies.8,9

of endodontics: The constricted envelope of
motion for instrumentation (Fig. 3) and the
use of hydraulics to enhance the rheology of
the obturation material used to seal the root
canal space and optimise its gravitometrics.
