Objectives: Untitled document
At the conclusion of this course, the student should be able to:
1. Describe the basic principles and concepts of radiation.
2. List the component parts and functions of the dental X-ray machine and describe the production of X-rays.
3. Explain the factors affecting the quality and quantity of the X-ray beam and how these factors affect the radiographic image.
4. Describe film composition, basic digital imaging components, and latent image formation.
5. Discuss film speed, sizes, types, digital image receptors and proper storage and protection.
6. Describe the effects of ionizing radiation on living tissue.
7. List radiation protection procedures for the operator and patient.
8. Describe intraoral techniques for bite-wings, and parallel and bisecting periapical radiographs.
9. Produce radiographic images of acceptable diagnostic quality with proper contrast, density, definition and minimal magnification or anatomic distortion.
10. Describe the purpose and uses of supplemental introral imaging techniques.
11. Demonstrate supplemental imaging techniques of occlusal, buccal object, distal-oblique third molar, vertical bitewings and pedontic bitewings utilizing correct positioning and exposure settings.
12. Explain the techniques of proper film handling, manual and automatic processing, and mounting of radiographs.
13. Explain the techniques of digital imaging process.
14. Describe the chemicals used in processing and the proper disposal techniques, as it relates to dental imaging.
15. State diagnostic procedures to align with quality assurance standards, relating to diagnostic radiographs.
16. Critically evaluate radiographic images to assess errors and indicate proper methods for correction.
17. Apply infection control techniques for prevention of disease transmission through demonstration of proper pre- and post-appointment operatory preparation procedures, instrument recirculation methods, and aseptic technique.
