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.
