Untitled document
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. Explain the techniques of proper film handling, manual and automatic processing and mounting of radiographs.
11. Explain the techniques of digital imaging processing.
12. Describe the chemicals used in processing and the proper disposal techniques, as it relates to dental imaging.
13. State diagnostic procedures to produce quality assurance, relating to diagnostic radiographs.
14. Critically evaluate radiographic images to assess errors and indicate proper methods for correction.
