1. 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.
Prerequisite: D H 60B.
Co-requisite: None
Advisory: None

2. 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.

8. Disciplines -
Dental Hygiene
9. Method of Instruction -
Lecture, Discussion, Laboratory, Demonstration.
10. Lab Content -
Lab exercises include applying the theory of dental radiographic localization techniques of the Buccal-object Rule and the Disto-oblique Projections on a training mannequin.
To support the dental hygiene clinic, students are required to complete on a patient a minimum of two full-mouth radiographic surveys and two bite-wing surveys with a passing score of 75% or greater.
11. Honors Description - No longer used. Integrated into main description section.
12. Types and/or Examples of Required Reading, Writing and Outside of Class Assignments -
  1. Students are required to read Chapter 21 from the course primary textbook on localization techniques
  2. Students will participate in the Technical Error Project designed to reproduce film errors and state the necessary corrections.
  3. An article by KODAK Dental Radiography Series, titled, "Successful Panoramic Radiography" sponsored by The Acaademy of Dental Therapeutics and Stomatology, will be read, followed by instructor-guided interpretation and analysis.
13. Need/Justification -
This course is a required core course for the AS degree in Dental Hygeine.
