|Student Learning Outcomes -|
- Demonstrate proper film placement techniques on a mannequin for intraoral films.
- List the name and functions of the processing solutions.
|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.|
|Course Objectives - |
|Expected Outcomes & Dental Hygiene Program Competencies |
The student will be able to:
Dental Hygiene Process of Care
Health Education Strategies
- demonstrate the ability to expose a six film posterior bitewing survey with a maximum of two retakes.
- demonstrate the ability to expose a full mouth 20 film survey with a maximum of four retakes.
- analyze the specific film fault or limitation by recognizing and describing the improper procedure involved.
- produce the correct film that improves the quality of the faulty radiograph.
- apply modified techniques to compensate for anatomical variations.
- describe the procedure for pedodontic bitewing survey.
Infection & Hazard Control Procedures
- describe the radiographic procedures for all patient needs; ie. those in pain and those with including full or partial dentition.
Ethical and Legal Principles
- demonstrate the ability to practice infection control in the radiographic clinical setting, and facilitate hazardous waste disposal of lead foil.
- exhibit attentiveness to patient's fears toward radiation.
- demonstrate a patient's right to privacy and confidentiality by not disclosing radiographic findings beyond the radiology lab.
