Course Description

Practices 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.
 

Outcome Assessment Strategies

Human Relations
Hours: 12

Outcomes:
 
Demonstrate the ability to expose, process and mount a full-mouth set of radiographs taken on a manikin using safe and effective techniques.
 
Activities:
 
Direct instruction on patient management techniques while performing radiograph exposures and peer evaluation techniques when critiquing dental films.
In addition, working as part of a team, students expose and develop radiographs on dental manikins utilizing team building concepts introduced in DA 111.
