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 requirments and is a prerequisite to DH 210, Advanced Radiographic Techniques. Co-requisite DH 109 Lecture.
Intended Outcomes for the course
1. Understand, relate, and apply radiographic principles and techniques by exposing appropriate diagnostic intraoral radiographs that utilize radiation health and safety standards for the operator and patient.
2. Recognize and relate radiology theory and application in preparation for tested portions on the Dental Hygiene National Board.
Course Activities and Design
Laboratory activities on Dental Manikins
Outcome Assessment Strategies
Successful completion of the following on a dental manikin:
- 4 full mouth radiographc surveys
- 5 adult bitewing radiographic surveys
- 1 pediatric bitewing radiographic survey
- 1 distal oblique radiographic survey
- 1 timed team project
- 1 final practical lab exam.
