When preparing a curved root canal be sure to check the working length with the electronic apex locator just before using the finishing file. This is a quick check to see if the canal has lost working length during preparation from straightening of the root canal and prevents over preparation of the apical foramen. Think of the Olympic race track where the runner who is in the outside lane runs the furthest.
