Dr. Levin has been invited to lecture at the Ottawa Dental Society’s Capital Dental Symposium III to be held in Ottawa, Canada on Friday, February 2, 2018. Dr. Levin will address the conference on the use of CBCT in endodontics and will base his program on the current literature. Central to his lecture are the limitations of intraoral radiography: compression of three-dimensional structures, geometric distortion, magnification and the misrepresentation of structures. Advantages of CBCT will also be discussed: three-dimensional assessment of odontogenic and non-odontogenic lesions, root canal morphology, revision treatment, root and alveolar fractures, resorptive lesions, anatomy prior to surgery and outcomes. This lecture will also describe new algorithms that allow clinicians to volumetrically measure lesions associated with apical periodontitis.
