Aplicações da tomografia computadorizada de feixe cônico na endodontia: revisão de literatura

Abstract

Cone-Beam Computed Tomography (CBCT) is a contemporary imaging system to assist in diagnosis and planning in dentistry. The strategy used to approach the subject was a narrative-type bibliographic review, which subsidizes the discussion of the main points and specificities of the subject. The objective of this work was to review the scientific literature on the TCFB, and its applications in endodontics, as its advantages and disadvantages. The studies obtained showed that periapical radiographs provide only two-dimensional (2D) information about the areas evaluated, while TCFB provides three-dimensional (3D) images, gaining importance in the indication of images due to the greater accuracy of the images, the understanding of sectional images, thus avoiding the need for repetition, making the possible information more accurate for a satisfactory treatment plan and a better prognosis. It was observed that TCFB plays an important role in endodontic diagnosis, facilitating the visualization of anatomical structures, identifying periapical lesions, location of root canals, resorptions and root fractures, in addition to assisting in parendodontic surgeries and in the making of endodontic virtual guides.
