Abstract

Background:Success in the endodonticoutcomerelies mostly on the correct determination of the apex.Findingsmay aid by which method endodontic working length determination is more accurate between cone beam C.T andapex locators.
Study objective:The study aim was to evaluate working length accuracy detection utilizing cone-beam computed tomography(CBCT)and electronic apex locator (EAL).
Materials and Methods: 32 extracted mandibular premolars and molars were scanned using CBCT.The measurements were gained from the reference point coronally to the apex were measured utilizing OnDemand3D software (Cybermed, Seoul, Korea) then using apex locator iPex II (NSK, Tokyo, Japan).
Results:No statistically significant difference between EAL working length and actual length while there was a statistically significant difference between CBCT working length and actual working length
Conclusion:Working length detection by apex locator was found to be more accurate than working length detection by CBCT while using actual working length as a gold standard.
Keywords: cone beam computed tomography, electronic apex locator, working length, accuracy, endodontic
