From: Study of the mandibular canal and its surrounding canals by multi-view cone-beam computed tomography
The same bony canal at the tooth apex can be observed on different surfaces. A1, B1, C1 Axial plane of the DVR. A2, B2, C2 Cross-section of the DVR. A3, B3, C3/A5, B5, C5 axial plane of the 3D. A4, B4, C4/A6, B6, C6 Sagittal plane of the 3D. The blue axis pointed by the red arrow in figures A3 and A5. By rotating the axis horizontally, the bony canal at the tooth apex (yellow arrow) can be observed from different angles. Pictures A, B, and C are from different tooth positions. Observed in the same way
