Working length determination [PDF]

British Dental Journal, 2021
The determination of accurate working length is one of the most critical step in the endodontic therapy. The cleaning, shaping and obturation cannot be accomplished accurately unless the working length is determined precisely. Thus, the predictable endodontic success demands an accurate working length determination of the root canal.
