This article aims to review about the clinical applications of CBCT. Diagnosis from CBCT influences clinical examination. CBCT is an emerging technology with the potential torevolutionize the diagnosis and management of endodontic problems. An increasing number of specific applications of CBCT in endodontics are being identified as use of this technology. CBCT is a relatively new method that produces three-dimensional information of the dental and surrounding structures. They have lesser radiation exposure than the traditional CT scans. CBCT is a advanced tool for diagnosing and managing endodontic problems, as well as for assessing root fractures, apical periodontitis, resorptions, perforations, root canal anatomy and the nature of the alveolar bone supporting the tooth.
