Each canal was coronally flared with a SX Protaper file. Working lengths were measured with K-files using electronic apex locators according to manufacturer instructions. The K-files were fixed at working length with flow light-curing composite. The apical 4mm of each canal was shaved to the major foramen exposing the file. The samples were observed under SEM and the distance from the tip file to the major foramen was calculated with the aid of a software for image analysis. Apex locator accuracy was classified as acceptable when the measurement was between the major foramen and -1mm. Results: The accuracy of the Raypex 5, Mini Apex locator and Elements Apex locator in locating the major...
