Accurate determination of working length is critical for the success of endodontic treatment. Inspection of pre-operative radiographs, use of tactile sensation, or evaluation of fluid on the tip of paper points may help with estimating working length. Modern electronic length measurement devices, such as the CanalPro™ Apex Locator™, provide a reliable method for confirming working length. Such devices determine the location of the apical constriction with the help of electrical resistance. Electronic length measurement is often more precise than radiographic determination of working length and can be repeated at any time to verify canal length. Working length should be measured after coronal flaring has been performed. Many canals have a coronal dentin shelf that, once removed, results in a straighter glide path and shorter working length. Obtaining working length prior to coronal flaring, therefore, can result in a working length that is inaccurate.
During the use of the CanalPro™ Apex Locator™, any of the following situations should be checked to avoid an erroneous reading:
