Abstract
Grade C periodontitis in young individuals is characterized by its early onset and rapid progression, resulting in swift periodontal tissue destruction in systemically healthy individuals. The application of laser technology in periodontal therapy has gradually increased in recent years. Laser therapy offers several advantages over traditional antibiotics, such as reduced patient discomfort, minimized postoperative edema, and a lower risk of drug-resistant strains. Recent studies suggest that laser-assisted treatments can significantly augment the clinical efficacy in managing grade C periodontitis. However, available evidence has not drawn distinct conclusions. This review aims to present the research progress in laser and antibacterial photodynamic therapy as the adjuvant treatment of grade C periodontitis in young individuals over the past decade, offering references for clinical practice.
