Cone beam computed tomography aided diagnosis and treatment of endodontic cases: Critical analysis

Figure 2 Radiological assessment of mandibular 1^st premolar tooth. A: Periapical radiography of the right mandibular 1^st premolar tooth showed a radiolucency at the periapical region. The root canal treatment seemed to be properly conducted; Panoramic (upper) and axial (lower) CBCT images (B) and (C) cros-sectional CBCT images of the same tooth obtained by Planmeca ProMax 3D Max CBCT unit (Planmeca Oy, Helsinki, Finland) with a flat panel sensor, operating at 96 kVp, 8.0 mA, using High Definition, 0.15 mm³ voxel size, and a 55 mm × 50 mm FOV shows an unfilled root canal related to periapical radiolucency; D: Periapical radiography of the same tooth taken after treatment. CBCT: Cone beam computed tomography; FOV: Field of view.
