Cone Beam Computed Tomography (CBCT) has progressed over 15-20 years from being a technique with great potential to one that has become primary diagnostic investigation. 3D imaging has made complex root canal anatomies more accessible and helps in accurate treatment planning for many endodontic problems. A modification of original cone beam algorithm was developed by Feldkamp et al in 1984. Since then there were significant progress in imaging technique starting from linear to hypocycloidal tomographic movements wherein the centre of rotation remains the same and movement of the equipment becomes more complicated for better resolution. The goal of this article is to summarize theapplications and limitations of CBCT in various clinical scenarios in day to day endodontic practice.
