New Dimensions In Endodontic Imaging-“Role of CT and CBCT in Periapical Lesion and Root Canal Anatomy”

Radiographs in endodontics are of importance for the study and management of periapical lesions and complex root canal anatomy. With the development of advanced systems in traditional radiology, new and more accurate imaging techniques are constantly under investigation. Conventional radiographs used for the management of endodontic problems yield limited information because of the two-dimensional nature of images produced, geometric distortion and anatomical noise. These factors often act in combination. This review paper assesses the limitations of periapical radiographs and seeks to clarify three-dimensional imaging techniques that have been suggested as adjuncts to conventional radiographs. These include computed tomography and cone beam computed tomography (CBCT).
