Current Edition: Volume 96
Targeted Supplementation and Nutrition for Periodontal and Systemic Health
Lorraine Gambacourt, RDH
Periodontitis is a chronic inflammatory disease driven not only by bacteria, but by an exaggerated inflammatory host response that can lead to connective tissue destruction, bone loss, and increased systemic inflammatory burden throughout the body. Nutrition plays an important role in the maintenance of periodontal health, however many individuals do not consistently consume optimal levels of key nutrients required to support healing, immune function, inflammation regulation, and periodontal stability. Deficiencies can exacerbate periodontal tissue damage.
This course will review a variety of vitamins, minerals and nutrients that play important roles in immune function, inflammation regulation, antioxidant defense, and tissue repair.
Learning Objectives:
1. Explain how inflammation and the host response affect periodontal and systemic health.
2. Identify supplements that may support periodontal healing, bone health, and inflammation control.
3. Evaluate current evidence supporting supplementation in periodontal therapy.
4. Differentiate supplementation approaches for periodontitis, maintenance, and peri-implant care.
5. Apply supplementation and nutritional discussions in client education and clinical practice.
