DENA 1031 - Dental Radiology I

Credits: 2
Hours/Week: Lecture 1 Lab 2
Course Description: The course focuses on the study and practical application of the principles of radiation safety, operating and maintaining radiographic equipment, and exposing and mounting diagnostically acceptable intraoral radiographs on mannequins. Students must be able to perform physical tasks to complete course requirements. A student who is pregnant requires a physician’s approval for course attendance because of radiation exposure.

Acceptance in the Dental Assisting Program is required.
