The introduction of cone beam computed tomography (CBCT) has created new diagnostic possibilities in dental medicine. Although computerized tomography (CT) has been available for quite some time, its use in dentistry has always been limited because of cost, access, and radiation. CBCT has been established as a valuable imaging technique in many dento-maxillofacial specialties, ranging from oral implant surgery to orthodontics. CBCT serves generally two main purposes withing these disciplines: diagnostic imaging and treatmemt planning. For the use of CBCT, one internationally accepted core principle is that all data accquired through the radiographic modality should be evaluated by a trained person. For CBCT, this implies that the whole volume should be analyzed, not only focusing on the basic question indicating the scan, but also accounting for incidental findings in the neighboring areas. It is reasonable to expect dentists to perform evaluation of images in the familiar area of teeth and their supporting structures, while advocating a specialist evaluation for other anatomical areas. For the use of CBCT, there is still considerable ambiguity in offering a decisive suggestion to routinely use this technique for diagnostic procedures. The main reason for this is that the radiation dose of CBCT, despite being lower than that of conventional CT, negates routine clinical usage, when one applies the principle of as low as reasonable achievable (ALARA). Recently, low-dose protocols have been recommended to assist practitioners in dose optimisation.
The present lecture will present and discuss specifically indications and limitations of CBCT use in dental medicine, and will also mention current and potential future developments in the field of diagnostic imaging.
Michael Bornstein (Prof. Dr. med. dent.) has been appointed in 2016 as Clinical Professor in Oral and Maxillofacial Radiology at the Faculty of Dentistry, The University of Hong Kong, Hong Kong SAR, China. In December 2018 he is been appointed as Associate Dean of « Research and Innovation » of the Faculty of Dentistry. He is Visiting Professor at the OMFS-IMPATH Research Group, Department of Imaging and Pathology, University of Leuven, Belgium. He obtained his dental degree (1998) and thesis (Dr. med. dent., 2001) at the University of Basel. He continued with a specialisation in oral surgery and stomatology in Basel (1998-1999, Prof. Dr. Dr. J. Th. Lambrecht) and Bern (2000-2002, Prof. Dr. D. Buser). In 2004, he was visiting assistant professor at the Department of Periodontics (Prof. Dr. D. Cochran) at the University of Texas Health Science Center at San Antonio, USA, with a grant from the Swiss National Science Foundation. From 2007-2014 he was head of the Section of Dental Radiology and Stomatology, University of Bern. In 2009, he obtained the Habilitation (Privatdozent / PhD) and in 2014 he became Asscociate Professor in the field of “Oral Surgery and Stomatology”.
His fields of research include cone beam computed tomography (CBCT) in clinical dental practice, diagnostic imaging, stomatology/oral medicine, GBR procedures and dental implants. He has published over 145 original articles, and is the author / co-author of numerous case reports, review articles, and book chapters.
Prof Bornstein has started a new position on January 2020 in the University of Basel, Switzerland, beginning from January 2020 as Clinical Director and Professor of the University Center of Dental Medicine Basel UZB, Department of Oral Health & Medicine Mattenstrasse 40, 4058 Basel, Switzerland
