1. Description -
Introduction to the radiology laboratory intended for the first year student enrolled in the dental hygiene program. Emphasis on dental x-ray techniques, film development and mounting. Radiation safety protection is practiced for all laboratory procedures. All films will be viewed for self-critique and instructor evaluation. Intended for students in the dental hygiene program.
Prerequisite: D H 60A.
Co-requisite: None
Advisory: None

2. Course Objectives -
Expected Outcomes & Dental Hygiene Program Competencies
The student will be able to:
Dental Hygiene Process of Care
  1. demonstrate the ability to expose a six film posterior bitewing survey with a maximum of two retakes.
  2. demonstrate the ability to expose a full mouth 20 film survey with a maximum of four retakes.
  3. analyze the specific film fault or limitation by recognizing and describing the improper procedure involved.
  4. produce the correct film that improves the quality of the faulty radiograph.
  5. apply modified techniques to compensate for anatomical variations.
  6. describe the procedure for pedodontic bitewing survey.
Health Education Strategies
  1. describe the radiographic procedures for all patient needs; ie. those in pain and those with including full or partial dentition.
Infection & Hazard Control Procedures
  1. demonstrate the ability to practice infection control in the radiographic clinical setting, and facilitate hazardous waste disposal of lead foil.
Ethical and Legal Principles
  1. exhibit attentiveness to patient's fears toward radiation.
  2. demonstrate a patient's right to privacy and confidentiality by not disclosing radiographic findings beyond the radiology lab.
3. Special Facilities and/or Equipment -
Dental radiology lab equipment: darkroom, red safety lights, automatic processors, processing cleaners, film, film cleaners, film holders, dental mannequins, viewbox, mounts, label maker, developer solution, fixer solution, hazardous waste containers, secondary containers, dental chairs, dental x-ray machine, digital sensor plates, scanner, computer, server, medical grade transparency film, internet access, duplicating machine, duplicating film.
