Fig. 4From: Root canal morphology of anterior permanent teeth in Jordanian population using two classification systems: a cone-beam computed tomography studyCBCT images sagittal and axial (coronal, middle and apical) views of mandibular canines showing two roots with variable levels for roots and canals splitting. A line is drawn from the CEJ to the root apex and the distance is divided into thirds. If the canal bifurcation occured in the middle or apical third then a superscript no “1” is added after the tooth number as displayed in the images (A to E)Back to article page
