Use of Cone Beam Computed Tomography in Endodontics
Figure 13
Traumatic injuries to the anterior dentition may result in a horizontal root fracture. Visualizing these fractures with periapical radiographs can be difficult as the beam must be in parallel alignment to the axis of the fracture. Conventional periapical image (a) shows horizontal radiolucent line separating the apical 1/3rd of the root. Note the loss of lamina dura and lateral radiolucency on the distal root surface adjacent to the horizontal radiolucency. Cross-sectional high-resolution (0.076 mm) image showing “V” shaped fracture and minimal displacement of the root segments. Note the loss of buccal cortical plate, widening of the buccal periodontal ligament space and periapical rarefaction.
