2 lecture periods 0 lab periods
Principles of dental radiography as a diagnostic aid. Includes radiation production and biology. Also includes clinic experience in exposing, processing, mounting, and interpreting radiographs on mannequins and patients using a variety of radiographic techniques.
Corequisite(s): DHE 101 , DHE 101LC , DHE 104 , DHE 104LB , DHE 107 , DHE 112 , DHE 116LC
Information: Students must be admitted to the PCC Dental Hygiene program and obtain consent of the Dental Hygiene department before enrolling in this course. DAE 163 can be substituted for DHE 116 if completed within the last three years, see academic advisor or faculty for information regarding course substitution. To substitute DAE 163 for DHE 116, student must have current CDA certification.
