A biometric study of C‐shaped root canal systems in mandibular second molars using cone‐beam computed tomography

Abstract

The most prevalent configuration types were Melton's type I (coronal region) and type III (apical region). The linguo-central root area was the thinnest in C-shaped root canals of Korean mandibular second molars. These anatomical variations should be considered during surgical or nonsurgical endodontic procedures.
