Figure 3: Computed tomography scan: (a) panorex view: unilocular, well defined, hypodense area extending from the mesial root of 2.4 up to the distal root of 2.7 and in the apicocoronal direction from the sinus floor to the alveolar ridge; (b) axial view: limited expansion and thinning of the buccal and palatal cortical plates, erosion of the buccal wall, and some small foci of radiopacity; and (c) coronal view: root resorption of the first molar.
