D'ADDAZIO, Paulo Sérgio dos Santos et al. The use of cone-beam volumetric tomography to help diagnose and plan a periapical surgery clinical case report. Odontol. Clín.-Cient. (Online) [online]. 2010, vol.9, n.4, pp. 377-380. ISSN 1677-3888.

The diagnosis and planning of interventions are vital for the execution of a surgical treatment. A method used routinely to help diagnose periapical lesions is the periapical radiography. However, with this technique, three-dimensional anatomic structures are compressed into two-dimensional images resulting in the superposition of structures of diagnostic interest. This article reports the clinical case of a patient who presented a cystic lesion of expressive dimensions in the anterior region of the maxilla, and whose surgery was planned and performed after visualization of the lesions' margins by means of Cone Beam Computed Tomography (CBCT). Thus, it is possible to determine that CBCT constitutes a precise method to help diagnosis, providing better accuracy for planning as it allows the three-dimensional visualization of structures.
