Course Description

Provides an opportunity to practice radiographic techniques on manikins, and patients correlating activities to the DA 120 lecture. Prerequisites: Acceptance in the Dental Assisting program. Corequisites: DA 120.

Intended Outcomes for the course

Upon completion of the course students should be able to:

  • Demonstrate how to use the correct settings for impulses, milliamperes, and kilovolt peak in radiography.
  • Expose Full Mouth Series (FMS) and Bitewings (BWXs) images on manikins and live patients, using digital technology in a safe and effective manner.
  • Chart and document according to industry standards.
  • Demonstrate proper infection control protocols.

Aspirational Goals

That all students are able to expose a Full Mouth Series (FMS) of images to industry standards.

Course Activities and Design

  • The activities in this course follow the lectures and class discussions in DA 120. This laboratory class provides the practical applications of radiographic principles and techniques
  • Laboratory applications provide opportunity to practice intraoral radiographic techniques on manikins and live patients. In addition, students practice peer-to-peer placement on one another, using safe and effective techniques - no exposures to x radiation 

Outcome Assessment Strategies

  • Lab practicals
  • Written comprehensive final
  • Attendance
  • Professional industry standards of behavior in the classrooms and laboratories
