CE Hours: 0

Course Description:

A vertical root fracture (VRF) is the modern dentist's clinical dilemma; it is elusive to diagnose and notoriously known for its very poor prognosis. Because of the limitations of conventional radiography, the application of high-resolution cone beam computed tomography (CBCT) imaging in detecting VRF has generated considerable interest. However, the generated image is one of the most difficult to interpret because of the presence of imaging artifacts that may obscure the putative fracture plane. Consequently, the ability of CBCT to detect VRFs in endodontically treated teeth is an important clinical question to address. The purpose of this presentation is to critically appraise the best clinical research available to demonstrate the diagnostic ability of CBCT in detecting VRFs in endodontically treated teeth.

At the conclusion, participants should be able to:

  • Describe the required steps in critical appraisal skills of diagnostic studies.
  • Evaluate the diagnostic ability of CBCT in detecting VRF in endodontically treated teeth.
  • Describe the probability that the interpretation of presence or absence of VRF is correct given the relationship between VRF prevalence and the CBCT predictive values.

Dr. Amir Azarpazhooh received his DDS from Iran (2001), his speciality training at the University of Toronto (UofT) in Dental Public Health (2007) and endodontics (2010), followed by his PhD in 2011. He is a UofT full-time tenured Associate Professor, with cross-appointments to the Clinical Epidemiology Program at the Institute of Health Policy, Management and Evaluation, Faculty of Medicine, and Toronto Health Economics and Technology Assessment Collaborative, UofT. He is also the Head of both Divisions of Endodontics and Research at the Department of Dentistry, Mount Sinai Hospital, Toronto.

Currently, his attributed grants and awards total more than CDN $1.25M and these have enabled him to manage a strong group of graduate students over the years. To date, he has been an editor of a textbook on evidence-based dentistry, has published six book chapters, and more than 150 papers, abstracts and reports and has presented at over 50 national and international scientific meetings. He has been awarded nationally and internationally, by the Cochrane Canada, the Canadian Academy of Endodontics, and the American Association of Endodontists. He is an Associate Editor of the Journal of Endodontics.

Amir is a practicing endodontist, with part-time private practices in Toronto as well as a hospital practice in Mount Sinai Hospital providing endodontic care to patients when their medical, physical or mental status indicates the need for a hospital environment. Despite his heavy load of teaching, research and clinical practice, out of the office he enjoys life with his wife, travelling, cycling, photography, and gardening.
