Catalog Description:

Students will focuses on the advanced imaging technique of extraoral panoramic dental radiology. The main emphasis is on developing proficiency in evaluating and interpreting intraoral and extraoral (panoramic) images, which entails recognizing anatomical landmarks, dental anatomy, restorations, and disease processes. Students must first demonstrate competency using manikins before providing services for patients. Students will gain the necessary skills and knowledge to confidently join the workforce in a clinical setting.

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 (interpretation) skills.

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

operator.

Objectives:

At the conclusion of this course, the student should 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.

13. Identify basic carious lesions on images and factors that would influence interpretation.

14. Describe the appearance on images of restorative materials such as amalgam, porcelain, gold, cements, and composites.  

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

16. Compare and contrast conventional film and digital imaging with respect to radiation exposure, equipment, image capture, maintenance and convenience.

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

18. Discuss duplication of films.
