Course DescriptionPractices radiographic techniques on manikins and correlate activities to the DA 120 lecture.
Intended Outcomes for the course
Demonstrate the ability to expose, process and mount a full-mouth set of radiographs taken on a manikin using safe and effective techniques.
Course Activities and Design
This course will be presented in a series of lecture and class discussions followed by a practical application of principles in the laboratory. Students will practice intraoral radiographic techniques on manikins and student student patients using safe and effective techniques. Direct instruction is given to complete peer evaluation portion of lab assignments.
