Cone-Beam Computed Tomography in Endodontics—State of the Art

Abstract

Cone-beam computed tomography (CBCT) is an imaging modality with high-resolution diagnostic value that provides accurate and high-quality three-dimensional information on the elements of the maxillofacial complex. Therefore, this study aimed to present an up-to-date status of the main indications for the use of CBCT in endodontics, and to discuss its main limitations relative to diagnosis in endodontics. The data captured by CBCT devices and processed by a specific software programs create a reconstruction of the scanned volume. Thus, they allow dynamic and interactive analysis of the information, by means of simultaneously scanning the object in different anatomical planes of imaging: axial, coronal, or sagittal, and their subsequent reconstruction thereby revealing structures that are not visible in periapical radiographs. Although periapical radiographs continue to be the imaging method of choice for the evaluation of endodontic treatment, a significant leap has occurred in the growth of CBCT use Endodontics in recent years. However, the importance of recognizing the different types of artifacts generated during the image acquisition and reconstruction process is emphasized, especially in the presence of high-density endodontic materials that can compromise the quality of the diagnosis. Considering the findings of this study, and based on international guidelines, it was concluded that the possibilities of using CBCT during endodontic treatment were mainly focused on diagnosis, assessment [of existent dental conditions], and preoperative treatment; establishing the morphology, diagnosis, and treatment planning of root canal systems; evaluation of root resorption; planning and evaluation of the treatment of traumatic dental injuries, perforations, fractures, and for the preparation of endodontic guides.
