Fig. 2From: Unusual root morphology in second mandibular molar with a radix entomolaris, and comparison between cone-beam computed tomography and digital periapical radiography: a case reportCone-beam computed tomography. a Sagittal view. Green line: coronal axis. Red line: axial axis. The axes are incorrectly oriented with respect to tooth 3.7. b Green line: coronal axis. Red line: axial axis. The axes are correctly oriented (parallel and perpendicular to the longitudinal axis of the tooth 3.7). c Coronal view. Yellow line: sagittal axis. Red line: axial axis. The axes are oriented incorrectly regarding the tooth 3.7. d Yellow line: sagittal axis. Red line: axial axis. The axes are correctly oriented. Section shows radix entomolaris type III curvature Abbreviations, L: lingual; B: buccal.Back to article page
