Student Learning Outcomes

  • Identify the anatomical components of the junctional epithelium and surrounding tissues on an unlabeled illustration, and analyze the functional roles of these structures in maintaining periodontal health and preventing disease progression.
  • List, describe, and differentiate periodontal diseases using the current classification system established by the American Academy of Periodontology.

Description

This is the first of two courses in periodontics designed for dental hygiene students. The course explores the anatomy and physiology of the periodontium, emphasizing the connection between foundational sciences and the clinical understanding of periodontal diseases. Students will gain knowledge of the most current classification system established by the American Academy of Periodontology, as well as the etiology and pathogenesis of periodontal diseases. This course prepares students with essential skills for delivering patient-centered periodontal care. Intended for students in the Dental Hygiene Baccalaureate Degree Program; enrollment is limited to students accepted in the program.

Course Objectives

The student will be able to:

  1. Identify and describe the functions of the four tissues that compose the periodontium.
  2. Compare and contrast the clinical and histological characteristics of the periodontium in health and disease.
  3. Explain the etiology of periodontal diseases, including the role of oral biofilms, immune and inflammatory responses.
  4. Identify the local contributing factors that affect periodontal disease.
  5. Describe the systemic risk factors that contribute to the progression of periodontal disease.
  6. Explain how periodontal disease may impact systemic health.
  7. Differentiate between the types and classifications of gingival and periodontal diseases using the current American Academy of Periodontology (AAP) classification system.
  8. Apply the AAP classification system to patient assessments.
  9. Describe the stages of periodontal diseases progression to support patient diagnosis and treatment planning.
  10. Outline the steps involved in completing a comprehensive periodontal examination to guide individualized patient care.
