These factors have stimulated the development of electronic root length measuring devices (apex locators), which accurately report the foramen or more precisely an area between the minor and major foramen diameter. Super imposition, anatomy interferences, distortion, shortening and elongation, interpretation variability, and lack of three-dimensional representation affect the correct interpretation of the images. ![]() However, the accurate determination of root canal length radiographically is hindered due to anatomical variations, interference of anatomical structures, or errors in projection. Radiographs are advantageous as the information they furnish, cannot be obtained from any other source and its value is not diminished by a critical appraisal of its limitations. To determine the working length, a number of techniques, including tactile sensation, radiographs, and electronic apex locators are routinely used in clinics.Ĭonventionally, conventional radiographs used to determine the working length which provides information about the canal anatomy and surrounding tissues. Failure to determine the proper root canal working length during root canal treatment may compromise the treatment result. A correct working length is a critical factor for the endodontic success. Working length is defined as the distance from a coronal reference point to the point at which canal preparation and filling should terminate. This can be achieved only if the length of the root canal is determined accurately. The removal of infected pulp tissue, necrotic material, and microorganisms from the root canal system is essential for endodontic treatment success.
