**5. Conclusions**

The help of CBCT technology in the diagnosis of endodontics either in the knowledge of the morphology and pathologies of the root canal system, in the evaluation of root and alveolar fractures, in the analysis of resorption, in the identification of pathologies of non-endodontic origin and in pre-surgical assessment, it is a very valuable method. Exact data lead to better treatment planning decisions giving more predictable results.

When comparing medical CT with CBCT it is verified that the accuracy has been increased, a higher resolution is obtained, the reduction of the exposure time, a reduction of the radiation and a lower cost for the patient is achieved.

Compared to conventional periapical radiography, CBCT eliminates the overlapping of surrounding structures by providing additional clinically relevant information.

Conventional two-dimensional radiographs remain the most accepted and used in endodontics imaging modality. These limitations arise mainly due to the inherent projection of a three-dimensional anatomy, which leads to geometric distortions and, consequently, misinterpretation.

Despite the obvious advantages of CBCT technology offered in the field of dentistry, there are some drawbacks and limitations as there is a growing concern among radiologists and maxillofacial about the increase in radiation on patients, in addition to the interpretation of these images require extensive knowledge of various structures. Because accurate diagnostic information leads to better clinical results, CBCT could prove to be a very valuable tool in modern endodontic practice [44].

CBCT's relatively modern technology has added another dimension to dental radiography and is rapidly becoming the gold standard for radiographic inspections in dentistry. At present, it cannot replace periapical radiography due to cost reasons and the degree of effective radiation [45]. However the techniques will improve to reduce the radiation dose and costs. CBCT currently has a reference place in endodontics, where the increase in the number of complex cases justifies the use of technology and the benefits to the patient are greater than the risks.
