Course Description

Introduces the uses of digital images in dentistry. Includes the history of radiation discovery, biological effects of X-ray in tissues, and safety principles. Includes identification of normal anatomy, and interpretation and identification of pathology seen on an intraoral dental image. Prerequisites: Acceptance in the Dental Assisting program. Corequisites: DA 121.

Intended Outcomes for the course

Upon successful completion of the course students should be able to:

  1. Identify individuals involved in the history of X-ray and X-radiation discovery.

  2. Describe intraoral techniques for digital imaging.

  3. Explain proper infection control and protocols when taking dental images.

  4. Explain protective measures when exposing dental images for both the patient and dental radiographer.

  5. Identify normal anatomy of intraoral images.

  6. Describe the characteristics if X-radiation.

  7. Describe the physics of X-radiation.

  8. Describe the biological effects of radiation on the human body.

  9. Identify dental materials seen on a dental image.

  10. Identify radiographic pathology seen on a dental image using descriptive terminology.
