Uso de tomografia computadorizada de feixe cônico no planejamento e tratamento endodôntico de canais radiculares - relato de caso

Abstract

The upper molars are the dental elements that present the most anatomical variations. Some of these variations can only be observed with CT scans, such as root canal variations. This may influence endodontic treatment planning. The objective of this clinical case was to present the importance of cone beam computed tomography in the planning and execution of endodontic treatment. In the present case, a 51-year-old female patient underwent a conventional periapical radiograph in which a periapical lesion was observed. It was then decided to carry out root canal treatment. However, during manual instrumentation of the mesiobuccal canal, the dentist found a transoperative bifurcation of the canal that was not visible on the conventional periapical radiograph performed. Therefore, a cone-beam computed tomography was requested. Through the tomographic examination, it was possible to observe the presence of some anatomical alterations, overlaps and information about the dental internal anatomy that directly influenced the execution of the treatment. Thus, tomography was of paramount importance for the success in the planning and execution of endodontic treatment, providing a wealth of details that could not be observed in conventional radiography.
