Objectives:
Untitled document
Students will 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 prupose and uses of supplemental introral imaging techniques.
11. Demonstrate supplemental imaging techniues of occlusa, 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 processing.
14. Describe the chemicals used in processing and the proper disposal techniques, as it relates to
dental imaging.
15. State diagnostic procedures to produce quality assurance, 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.
