Student Learning Outcomes -
  • Understanding the parameters of the California State Board Exam requirements for a FMS, the student will be able to evaluate the need to retake a dental radiograph
  • Identify calculus on a full mouth set of radiographs.
Description -
Final course in a series on dental radiography for students enrolled in the dental hygiene program. Increase in patient requirements and the attainment 90% scores or higher on film evaluations. Emphasis is on time efficiency, technique accuracy and patient management. Increased skill in film exposures, processing and the interpretation of dental diseases. Intended for students in the dental hygiene program.

Course Objectives -
Course Objectives and Dental Hygiene Program Competencies
The student will be able to:
The Hygiene Process and Care
  1. demonstrate the ability to expose a six film posterior bitewing survey with open contacts.
  2. demonstrate the ability to expose a full mouth 20 film survey with a maximum of four takes.
  3. identify radiographic anatomical landmarks.
  4. identify basic film exposure and processing faults.
  5. demonstrate the procedures for the expsosure of the occlusal and distal-oblique films
  6. demonstrate the ability to process film utilizing the digital process.
Health Education Strategies
  1. demonstrate radiation safety and protection for the patient and operator.
  2. understand patient concerns of radiation over-exposure and address those concerns using sound theoretical principles
Infection & hazard Control Procedures
  1. demonstrate infection control procedures for the radiographic procedure.
  2. facilitate hazard control procedures for processing solutions.
Ethical & Legal Principles
  1. evaluate the need for dental radiographs according to the ADA guidelines for radiographic prescribing.
  2. perform nonmaleficence by using all measures to protect the patient from receiving unnecessary radiation.
