Use of Cone Beam Computed Tomography in Endodontics
Figure 14
This patient was referred for endodontic revision of the mandibular right lateral incisor. Initial periapical radiographic examination of the mandibular anterior teeth including the left anterior (a) was unremarkable. Note the appearance of a large radiolucency at the on the distal surface of the left canine due to nonperpendicular X-ray beam projection of the distal curvature of the cervical margin. CBCT images ((b) right cross-sectional, (c) left cross-sectional, (d) axial) demonstrated an occult finding of early ERR on the mandibular left and right mandibular cuspids. Early detection and classification of the lesion improve the prognosis and assist in early direct treatment consisting of surgical exposure and removal of granulation tissue from the resorbing lacunae and sealing.
