Electronic Apex Locators May Be Better at Determining Endodontic Working Length Than Radiographs and Could Reduce Patient Radiation Exposure

Abstract

Clinical efficacy of electronic apex locators: Systematic review. Martins JNR, Marques M, Mata A, Carames J.J Endod 2014;40(6):759-77. Nicholas Chandler, BDS, MSc, PhD, LDSRCS, MRACDS (Endo), FDSRCPS, FDSRCSEd, FFDRCSI PURPOSE/QUESTION: The authors conducted a systematic review to compare radiographic and electronic methods of determining endodontic working length. The authors reported no external funding sources. Systematic review Level 2: Limited-quality patient-oriented evidence STRENGTH OF THE RECOMMENDATION GRADE: Grade B: Limited-quality patient-oriented evidence.
