Description -
Radiology course intended for second year students enrolled in the dental hygiene program. Emphasis on the understanding of radiographic interpretation of periodontal and dental diseases. Continued application of digital radiography with use of sensors and scanners. 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 the need for dental radiographs according the ADA guidelines for radiographic prescribing.
  2. identify skull anatomical landmarks on the radiograph
  3. detect normal landmarks vs. atypical landmarks.
  4. identify basic film exposure and processing faults.
  5. demonstrate the procedures for the expsosure of occlusal films.
  6. demonstrate the ability to produce digital radiographs.
Health Education Strategies
  1. apply correct guidelines for radiation safety for protection of the patient and the operator.
  2. understand patient concerns regarding radiation exposure and clarify misconceptions using sound theoretical principles
Infection & Hazard control Procedures
  1. correctly perform infection control procedures for the taking and processing of radiographs
  2. list the hazardous materials located in the darkroom
Ethical & Legal Principles
  1. accurately recite the ADA guidelines involving the prescription of bitewing and full mouth radiographs
  2. maintain the patient's right to privacy while performing all radiology procedures
