Estimation of Gingival Crevicular Fluid levels of Uric Acid and Xanthine Oxidase in Patients Diagnosed with Chronic Periodontitis: A Prospective Interventional Study

G Sumanth Babu, Lavanya R

Abstract: Background: Periodontitis is a chronic inflammatory disease characterized by progressive destruction of the supporting structures of teeth. Oxidative stress plays a crucial role in this process, with reactive oxygen species amplifying tissue damage. Uric acid and xanthine oxidase, important oxidative mediators, have established roles in systemic inflammation but remain under-investigated in periodontitis. Aim: To evaluate gingival crevicular fluid (GCF) levels of uric acid and xanthine oxidase in patients with periodontitis before and after non-surgical periodontal therapy (NSPT). Methods: Twenty adult periodontitis patients underwent comprehensive clinical assessment and GCF sampling at baseline and three months post-NSPT. Biomarker levels were quantified using ELISA. Clinical parameters assessed included Plaque Index, Gingival Index, Bleeding on Probing, Probing Pocket Depth, and Clinical Attachment Level. Results: Significant reductions in GCF uric acid and xanthine oxidase levels were observed following NSPT (p
