Periodontal disease is a chronic inflammatory condition affecting tooth-supporting structures. It's a key focus in plasma medicine due to its significant impact on oral health. Understanding its etiology, classification, and symptoms is crucial for developing effective plasma-based treatments.
Conventional treatments like scaling, root planing, and surgery form the foundation of periodontal therapy. Plasma-based interventions aim to enhance these methods. Cold atmospheric plasma devices, plasma-activated water, and plasma-enhanced antimicrobial effects offer novel approaches to managing periodontal disease.
