Maxillofacial Radiology (CBCT)

2019-2020

Course Objective

Competences covered according to the General Educational Framework
Dentistry 2008: VI e (5)

The student
• has an understanding of the technique of ConebeamCT scanners and
how a CBCT-image is reconstructed from the photons that hit the detector
of the machine after attenuation by the patient.
• has a deep understanding of the effect of several parameters,
including radiation settings, patient factors, detector characteristics
and image processing, on the quality of the resulting image set.
• has an understanding of specific image artifacts that occur in
CBCT images
• has an understanding of the radiation risks and radiation
protection
• has an understanding of the legal framework of operating
ConebamCT machines
• can apply the European evidence based guidelines on the use of
ConebeamCT in dentistry in relation to the justification of ConebeamCT
scans in all applicable areas of dentistry
• know the place of Dental conebeamCT within the range of the
diagnostic possibilities in dentistry, in relation to diagnostics,
anatomy as well as pathology.
• has an understanding of the infrastructure needed when
implementing a ConebeamCT machine in clinical practice, such as IT-
infrastructure, DICOM and file transfer.

Course Content

The course prepares for the official Dutch license as radiation officer
to operate Conebeam Computer Tomography (ConebeamCT ) devices. During
this course, the students will be trained in various aspects of the use
of ConebeamCT in oral diagnosis. The use of ConebeamCT may aid to the
diagnosis of the patient, however the increased radiation dose compared
to other modalities should be taken into account in the justification
process. Evidence-based justification of ConebeamCT scans therefore
plays a key role in this course. Also the application of the As Low As
Reasonably Achievable / As Low As Diagnostically Acceptable (ALARA/ALADA
principle) in the use of ConebeamCT will be elucidated and emphasized.
At the basis of correctly applying the justification- and ALARA
principle lies a thorough knowledge of the ConebeamCT technology and
radiation aspects. Imaging technique, image quality, and common
artifacts will be discussed, as well as (X-ray) radiation aspects
influencing image quality and patient dose. Dosimetry and radiation
protection in the clinic, as well as existing (legal) requirements will
be discussed and interpretation and diagnosis on CBCT images of oral and
maxillofacial anatomy, followed by pathology in the same area, will be
lectured and practiced. Image processing, storage, and communication are
also addressed in this course. This course will be taught to 2nd and 3rd
year OHS students. The second-year OHS students will deliver an
interdisciplinary presentation (case report incl. scientific background)
on the use of Conebeam CT in their respective patient care worth 1 extra
EC.

Teaching Methods

Self-study; Online lectures; Lectures; Practical training; Home-work

Method of Assessment

Learning assessment
Third year students:
• Official Computerized test (grade: 1-10)

Second year students:
• Official Computerized test (grade: 1-10)
• Presentation (grade: Good; Pass; or Fail)

Grading 2nd year students:
• A prerequisite for grade registration (grade 1-10) is successful
completion of the presentation. In case of a fail for the presentation
and a pass for the final exam, a 5.0 will be registered and students
will need to redo the presentation.

Additional Information

Admission prerequisites: Basic knowledge of radiation and radiation
protection.
Students receive a certificate upon successful completion.
