COURSE CONTENT

Student Learning Outcomes:
At the conclusion of this course, the student should be able to:

1.  Demonstrate an expanded knowledge of oral imaging, including proficiency in basic and

    advanced exposure techniques and identification skills.

2.  Consistently demonstrate comprehension of radiation safety as it relates to the patient and

    operator.

Objectives:

Students will be able to:

1.   Demonstrate intraoral and panoramic radiological imaging on manikins utilizing correct

      safety precautions, positioning, exposure settings, and processing or image capture

      techniques.

2.   Demonstrate intraoral and panoramic radiological imaging on patients utilizing correct

      infection control, safety precautions, positioning, exposure settings, and processing or

      image capture techniques.

3.   Discuss principles of infection control utilized in operatory preparation, film or sensor use

      and processing contaminated film.

4.   Implement appropriate radiation protective measures for the protection of the operator and

      the patient utilizing the ALARA (as low as reasonably achievable) principle.

5.   Discuss the use of quality control measures to assure the production of diagnostic images.

6.   Discuss safety and environmental responsibilities for dental radiography.

7.   Demonstrate anatomical film mounting.

8.   Discuss the advantages and disadvantage of panoramic radiography.

9.   Define the roles of the dental auxiliary and the dentist in image evaluation, interpretation and

      diagnosis.

10. Evaluate intraoral and panoramic images for errors based on diagnostic image criteria.

11. Identify normal anatomical landmarks of the maxilla and mandible on intraoral and

      panoramic images.

12. Identify normal dental deviations from normal anatomy resulting from trauma, disease, and

      developmental conditions.

14. Basic carious lesions on images and factors that would influence interpretation.

15. Describe the appearance on images of restorative materials such as amalgam, porcelain, gold,

      cements, and composites.  

16. Describe the purpose and uses of supplemental intraoral imaging techniques.

17. Demonstrate the supplemental imaging techniques of occlusal, buccal object, distal-oblique

      third molar, vertical bitewings and pedodontic bitewings utilizing correct positioning and

      exposure settings.

18. Describe the uses of extraoral imaging and the purpose of each of the extraoral projections.  

19. Compare and contrast conventional film and digital imaging with respect to radiation

      exposure, equipment, image capture, maintenance and convenience.

20. Describe modifications in technique for special needs patients, and pedodontic patients.

21. Discuss duplication of films.
