Applications and advantages of the use of cone-beam computed tomography in endodontics: An updated literature review

Abstract

Introduction: To assess the potential uses and benefits of cone-beam computed tomography (CBCT) in the field of endodontics, where the anatomy evaluated is complex, and to summarize the possible advantages over two-dimensional (2D) radiography. Methods: For this study, a review of the literature of the last 13 years was carried out in the PubMed and Google Scholar databases by using the following keywords: CBCT, dental radiography, endodontic diagnosis, management of endodontic problems; 3D imaging. Moreover, inclusion and exclusion criteria were applied. Results: A total of 29 articles were selected because they fulfilled the inclusion criteria. Articles were analyzed to investigate the advantages, limitations, radiological aspects, and uses of CBCT in endodontics from a critical point of view. Conclusions: Conventional radiography continues to be the main diagnostic method in endodontics, but taking into account the as low as reasonably achievable principle, in cases in which there are inconclusive signs and symptoms with 2D radiography, CBCT is a useful complement in endodontic diagnosis and allows a more accurate and predictable treatment plan design.
