Course DescriptionCovers basic theory of dental radiography. Includes intra-oral techniques with emphasis on radiation safety practices and techniques. Corequisites: DH 109L.
Addendum to Course Description
DH 109L will provide basic knowledge and skill in radiation physics, function and operation of dental x-ray equipment, intraoral and selected extraoral radiographic exposure techniques, dental film composition, handling and processing procedures as well as radiograph interpretation. In addition, the student will develop knowledge of the biological effects of radiation and demonstrate an understanding of safety principles for both operator and patients. The student will spend 3 hours per week in laboratory sessions learning exposure techniques on manikins and processing of films. This course meets specific graduation requirements and is a prerequisite to DH 210, Advanced Radiographic Techniques. Co-requisite DH 109 Lecture.
