Detection of the second mesiobuccal canal in mesiobuccal roots of maxillary molar teeth <i>ex vivo</i>

Abstract

Both magnification (stage 2) and dentine removal under magnification (stage 3) were effective in detecting the presence of the MB2 canal. However, MB2 canals could not be detected in 13% of the teeth because of canal calcification or branching located more apically.
