Application of Cone Beam Computed Tomography in Endodontics: A Review Article

Background and Aim: Cone beam computed tomography (CBCT) has attracted consider- able attention as a new diagnostic imaging technique in dentistry. The aim of this study was to review its application in Endodontics. Materials and Methods: Electronic databases (MedLine, EMBase, Cochrane, Iran Me- dex, Science citation index, Scopus and Google scholar) were searched by the authors for articles published from 1999 to 2012. "CBCT imaging", "Endodontics", "vertical root fracture or VRF" and "periapical or PA lesions" were the searched key words. Results: The assessment of PA lesi ons, healing process, tooth morphology, accessory canals, root curvature, traumatic injuries, internal and external tooth surfaces, root resorp- tion, fracture lines specially vertical root fracture, perforations, broken instruments, over- extended filling materials, calcified canals, proximity and superim position of roots and pre-surgical evaluation are the challenges that cannot be adequately addressed by conven- tional radiography. Conclusion: Cone beam computed tomography is a valuable imaging modality with mi- nimal radiation exposure to the patient that provides maximal information for the clini- cian. It is going to be the front-line dental imaging modality in near future.
