Course Number and Title: DHY 141 Oral Radiography
This course introduces the principles, theories, and techniques of dental oral radiography. Students practice exposing, mounting, and evaluating dental radiographs for the development of clinical radiographic skills. The paralleling technique using digital radiography is stressed.
