Part 1: X-ray Machines and Digital Image Detectors
How X-ray machines work and the differences between an intraoral X-ray machine and a medical CT. Digital image detectors: phosphor storage plates and solid state sensors – advantages and disadvantages.
Part 2: Radiation Doses and Radiation Protection
Absorbed, equivalent and effective radiation doses and how they have to be interpreted and put into perspective to annual natural background radiation. Examples of different diagnostic radiographic examinations used to illustrate the magnitude of dental and medical radiography (2D and 3D) doses. Useful when dentists receive legitimate questions about radiation and doses, and in particular if children are subjected to ionizing radiation. Radiation protection measures such as thyroid gland collars, discussed.
Part 3: Radiographic Techniques for Dentistry
Different techniques that can be used and modified to obtain the best image quality possible for each circumstance and patient. Indications and contra-indications, advantages and disadvantages. Principles of ultrasonography and magnetic resonance imaging (MRI) explained and compared to the ionizing radiation techniques, with regard to use and application fields. Learn when to refer a patient and for which technique to obtain the best diagnostic image and information.
Part 4: Interactive Radiographic Diagnosis Session
Normal anatomy, aberrant anatomy, incidental findings and pathology discussed using clinical examples. Intraoral radiographs, panoramic radiographs, CBCT etc will be used. Interaction with colleagues in the audience. Identification of anatomy and pathology is a crucial step in the diagnosis process. A myriad of radiographs will be presented spread out over different patient age groups, for exposure to a wide range of diagnoses.
Learning Outcomes / Course Objectives:
At the end of the lecture day, the attendees should be able to:
Explain and understand the differences between a dental and medical X-ray machine.
Put radiation doses from diagnostic imaging into perspective and to use the right measures regarding radiation protection.
Select the correct imaging technique for specific clinical situations and understand its limitations and indications.
Recognise aberrant anatomy, artefacts and pathology on different types of radiographs used in dentistry.
