Aplicações de tomografia computadorizada na cirurgia de dentes inclusos.

Abstract

Objective: It is necessary to use criteria based on the scientific literature, in order to obtain the correct indications for the use of cone beam computed tomography (CBCT). Therefore, the objective of this work is to search in the literature, what are the applications of cone beam computed tomography in minor oral surgery, mainly addressing the surgery of impacted teeth. Materials and methods: A bibliographic survey was carried out in the PubMed database, selecting the descriptors impacted teeth AND preoperative planning AND cone beam computed tomography. Results and discussion: We found 10 articles published in the period from 2002 to 2018, where all were selected. We can observe that the CBCT has a better performance when looking for a better evaluation of the cases, however due to cost, radiation quantity, availability of devices, its use ends up being restricted to more specific cases. The CBCT is essential to arrive at the diagnosis, evidencing the location of three-dimensional plane teeth and besides showing its relation with adjacent structures, also shows us aspects of the dental morphology. Final considerations: CBCT is indicated for extraction of impacted canine when it is desired to obtain a precise location of the dental element within the bone structure and its relation to the adjacent structures and in third molar surgery when assessing the relation of the apex to the nerve inferior alveolar, in cases in which the panoramic radiography shows intimacy of the roots with the mandibular canal, improving the planning and bringing benefits to the patients.
