Laser-Assisted Periodontal Therapy versus Traditional Scaling and Root Planing: A Clinical and Microbiological Study.

Introduction: Periodontal disease is a significant health issue resulting from the accumulation of biofilm, leading to inflammation and tissue destruction. Traditional "scaling and root planing (SRP)" is the gold standard for managing periodontitis, while "laser-assisted periodontal therapy (LAPT)" is gaining popularity as an adjunctive treatment. This study aims to compare the clinical and microbiological outcomes of LAPT versus SRP. Methods: A randomized controlled trial was conducted on patients with chronic periodontitis. Clinical parameters, such as "probing depth (PD), clinical attachment level (CAL), and bleeding on probing (BOP)," were assessed. Subgingival plaque samples were collected and analyzed for microbiological evaluation. Participants were divided into two groups: SRP-only and SRP + LAPT. Follow-up evaluations were conducted at baseline, three months, and six months posttreatment. Results: Both groups showed significant improvements, with the LAPT group demonstrating a more substantial reduction in PD and BOP. Microbiological analysis revealed a greater reduction in pathogenic bacteria in the LAPT group. Conclusion: LAPT, when combined with SRP, showed superior clinical and microbiological outcomes compared to SRP alone. The findings suggest that LAPT is an effective adjunctive therapy in periodontal treatment.
