Student Learning Outcomes -
  • Correctly mount a full mouth survey of dental radiographs.
  • Recognize periodontal bone loss on a dental radiograph.
Description -
Radiology course for second year dental hygiene students. Emphasis on correlating oral diseases to radiologic findings. Includes distal-oblique projections and application of the S.L.O.B. rule. Introduction to digital panoramic radiology. Intended for students in the dental hygiene program.

Course Objectives -
Course Objectives and Dental Hygiene Program Competencies:
The student will be able to:
Dental Hygiene Process of Care
  1. identify all diagnostically usable film
  2. detect the specific fault or limitation of any non diagnostic film
  3. analyze the correction needed to improve the quality of each faulty radiograph
  4. evaluate the need to use modified techniques to compensate for anatomical variations
Health Education Strategies
  1. describe the radiographic procedures for all patient needs, including full, partial, edentulous, and pedodontic patients
  2. exhibit attentiveness to patient's fear toward radiation
Infection and Hazard Control Procedures
  1. demonstrate the ability to correctly practice infection control in the radiographic clinical setting
  2. demonstrate correct hazardous waste disposal of lead foil
Ethical and Legal Principles
  1. describe the guidelines for the prescription of dental radiographs according to the ADA guidelines.
  2. demonstrate fidelity and abide by radiation safety rules by placing a lead shield and thyroid collar on each patient.
