Brief summary

Background: Periodontitis is a chronic inflammatory disease characterized by the destruction of tooth-supporting tissues, driven by an imbalance between bacterial pathogens and the host immune response. This inflammatory process leads to the excessive production of reactive oxygen species (ROS), causing oxidative stress and tissue damage. Melatonin is a potent antioxidant and immunomodulator that scavenges free radicals and reduces inflammation. Previous research indicates that salivary and gingival crevicular fluid (GCF) melatonin levels are significantly reduced in patients with periodontitis compared to healthy individuals, suggesting its potential utility as a biomarker for periodontal health. Aim: The aim of this study is to evaluate the efficacy of 2% melatonin gel administered locally into periodontal pockets as an adjunct to subgingival instrumentation in patients with Stage II Grade B periodontitis.

Interventions

OTHER2% Melatonin gel

All qualifying periodontal pockets on the randomly assigned test side will receive Non-Surgical Periodontal Therapy (NSPT) followed immediately by the subgingival application of 2% Melatonin gel.

OTHERPlacebo Gel

All qualifying periodontal pockets on the contralateral side will receive Non-Surgical Periodontal Therapy (NSPT) followed immediately by the subgingival application of the Placebo gel.
