COURSE CONTENT

Student Learning Outcomes:
At the conclusion of this course, the student should be able to:

1.  Explain the principles of radiation, infection control, safety and quality assurance, as they

    apply to dental radiography.

2.  Produce diagnostically acceptable radiographic images utilizing bite-wing, parallel and

    bisecting techniques.

Objectives:

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.

15. 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.
