Abstract :
Working length is defined as the distance
from a coronal reference point to a point at which the
canal preparation and obturation should terminate.
Accurate determination of working length is crucial to
prevent under-instrumentation or over-instrumentation,
which can lead to complications such as apical leakage,
patient discomfort, and treatment failure. The standard
technique for determining canal length uses the
radiological interpretation of file length in respect to the
radiographic apex, but this method has limitations due
to distortions and errors in interpretation. Therefore,
digital working length determination namely electronic
apex locators, cone-beam computed tomography, and
audio metric methods are being investigated for better
precision and accuracy. The paper concludes that a
combination of digital and radiographic methods is the
best approach for determining working length
accurately.
