Oral and maxillofacial radiology is the branch and specialty of dentistry concerned with the prescription, production, and interpretation of diagnostic images for the diagnosis and management of diseases and disorders of the craniofacial complex.


The NDSE in oral and maxillofacial radiology evaluates your knowledge and clinical competence in oral and maxillofacial radiology at the specialty level.


Canadian oral and maxillofacial radiologists are required to have broad knowledge and skills in five domains. The blueprint below presents the domains and the approximate percentage of the examination covered by each domain. 

Oral and Maxillofacial Radiology Blueprint - Part 1

% of
Radiation Sciences 12.5
Imaging Techniques 12.5
Head and Neck Anatomy 12.5
General Head and Neck Pathology 12.5

Oral and Maxillofacial Radiology Blueprint - Part 2 Approximate
% of
Interpretation of diagnostic imaging of the maxillofacial region 50
Total 100%


The examination will consist of two three-hour parts. Part 1 will consist of short answer and essay type questions, and Part 2 will consist of sets of patient diagnostic images for the candidate to interpret.

Case Interpretation

Part 2 of the oral and maxillofacial radiology examination consists of 12 cases to interpret.

The images will be presented in the following formats:

  • CBCT volumes with Anatomage Invivo Dental Viewer
  • MDCT and MRI volumes with Synaptive Medical ClearCanvas Software
  • CBCT and MDCT MPA movie files.
  • PowerPoint files
  • Jpeg files

For each of the 12 cases, you will be asked to:

  • Identify the diagnostic image(s) provided, including image modality/ies and anatomical areas depicted. Please note that the entire case is the subject of the report — not the individual images.
  • Describe the pertinent findings on the imaging examination(s) in the format of a radiology report.
  • Provide a differential or definitive interpretation of the abnormality/ies.
  • Give the etiology/pathology/cause of disease/disorder.
  • Comment on the management of the case (where applicable, additional imaging, biopsy, bloodwork, or other diagnostic tests that may be indicated to provide further information for patient management).

Software and Sample Files

During the examination, you will be provided with a laptop on which you will find the software and case files for Part 2.

In preparation for the examination you will be provided access to a series of practice files that can be loaded using Synaptive Clear Canvas and Invivo Dental Viewer. A link to the sample files will be sent to you through the secure messages feature of your NDEB profile once you have applied and identified oral and maxillofacial radiology as your specialty.
