1. Description -
Continuation of DA 53B. Intraoral technique and film evaluation skills practiced on mannequins and performed on patients. Emphasis on endodontic, occlusal distal-oblique and digital radiographs. Intended for students in the dental assisting program.
Prerequisite: Admission to Dental Assisting Program.
Co-requisite: None
Advisory: None

2. Course Objectives -
Expected Outcomes & Dental Assisting Program Competencies
The student will be able to:
Dental Assisting Theory and Practice
  1. As prescribed by the dentist,
    1. Expose a diagnostically useful 6 film bitewing survey with no more than two retakes.
    2. Process and mount the bitewing survey without errors.
    3. Expose a diagnostically useful 20 film full mouth survey with no more than 4 retakes.
    4. Process and mount the full mouth survey without errors.
  2. accurately record the radiographic procedure performed in a patient's dental chart
  3. Exhibit attentiveness to patient fears toward radiation
  4. Expose on a mounted mannequin, an upper and lower occlusal film demonstrating:
    1. proper density and contrast
    2. adequate view of the area being survey
  5. Produce a diagnostic digital panoramic radiograph.
Infection Control and Hazardous Waste Management
  1. demonstrate correct infection control procedures in the lab for the prevention of cross contamination.
  2. demonstrate the proper disposal of lead foil
Ethical and Legal Principles
  1. list the types of illegal computer modification that can be made with digital radiographs.
  2. demonstrate nonmaleficence or first, "do no harm" to each patient by placing a lead shield prior to radiation exposures.
3. Special Facilities and/or Equipment -
  1. Gown, safety glasses, masks, and gloves.
  2. X-ray laboratory,darkroom facility, mannequin, panoramic unit, view boxes, film, digital sensors and digital scanner.

    4. equipment preparation
    5. vertical angulations of tubehead
5. Repeatability - Moved to header area.
 
6. Methods of Evaluation -
Including but not limited to lab assignments, patient requirements and quizzes. Students analyze and evaluate all prescribed dental radiographs for diagnostic quality. Application of technical corrections are applied to diagnostic errors.

Dental Assisting
 
9. Method of Instruction -
Laboratory demonstration and observation. Film grading and feedback on all radiographs taken on patients.
 
10. Lab Content -
