Course Learning Outcomes
  1. Collect assessment data to assist with developing a dental hygiene care plan and formulating a dental hygiene diagnosis, using the dental hygiene human needs concept.
  2. Implement any necessary modifications to dental hygiene care and oral health education for patients with systemic disease, physical, cognitive and sensory disabilities.
  3. Implement available treatment alternatives that relate to periodontal disease and the specific treatment that satisfies the needs for patient oral health.
  4. Demonstrate intermediate to advanced instrumentation skills with a vast variety of dental instruments.
  5. Synthesize oral health services of diverse patient population groups through community health learning activities.

Performance Objectives:
  1. Provide home care instructions based upon patient needs and interest level.
  2. Provide nutritional counseling service to clinical patients as treatment planned.
  3. Write up a dental hygiene treatment plan for patient services.
  4. Formulate a dental hygiene diagnosis.
  5. Respond to any medical emergencies.
  6. Record findings from initial extra-oral and extra-oral exams.
  7. Complete a periodontal record for baseline information and provide updates for a clinical patient under treatment.
  8. Explain etiology and prognosis of dental disease so that the patient understands his role in home care.
  9. Expose radiographic surveys after determining the patient’s needs and diagnostic yield including the need for the treatment of periodontal diseases.
  10. Use radiographic surveys to detect abnormal tissues, detect calculus, critique technique, and identify normal landmarks.
  11. Demonstrate treatment procedures for medically compromised patients with the implementation of appropriate precautionary measures.
  12. Consult with the patient’s physicians in determining the appropriate modification in dental hygiene service for each patient recognized as medically compromised.
  13. Prepare dental hygiene treatment plans for patients who exhibit intermediate levels of periodontal disease.
  14. Integrate preventative measures, along with periodontal disease control services, for each patient indicated for these services.
  15. Explain and establish referrals to the dental specialties for patients who require additional dental treatment.
  16. Integrate dental care with a total approach to provide optimal health care.
