This course introduces the fundamentals of periodontology, with an emphasis on the anatomy, physiology, neurology, lymphatics, and hematology of the periodontium in health and disease. Students will explore the epidemiology, classification, and etiology of periodontal diseases, including gingivitis and periodontitis. Clinical and radiographic assessments, the human immune response to periodontal pathogens, and the impact of systemic conditions on periodontal health are examined to support evidence-based treatment planning and patient education.
