Abstract

Diagnosis of periodontal disease is based on clinical signs and symptoms. However, when there is bone destruction, radiographs are convenient diagnostic method for clinical examination. Two-dimensional periapical and panoramic radiographs are frequently used for diagnosis. In 2D imaging, bone craters, lamina dura, and periodontal bone level evaluation are limited by projection geometry and superimpositions of adjacent anatomical structures. These limitations can be eliminated by the use of three-dimensional imaging techniques such as computed tomography (CT). Cone-beam CT (CBCT) generates 3D volumetric images. CBCT displays 3D images that are necessary for the diagnosis of intrabony defects, furcation involvements, and buccal/lingual bone destructions. Its applications provide benefits in periodontics, however; it should be used only considering the necessity and the potential hazards of the examination.
