Influence of embedding media on the accuracy of working length determination by means of apex locator: an ex vivo study

Abstract The aim of this research was to determine ex vivo the influence on accuracy of five different embedding media, for investigative and educational purposes, and one electronic apex locator. 110 human extracted mature roots of permanent single-rooted human teeth were used. The roots were embed...
