Relationship Between LRG and Periodontal Disease

Not Applicable

Completed

• Conditions: Inflammation; Periodontitis; Acute-Phase Response

• Registration Number: NCT04383561
• Lead Sponsor: Aydin Adnan Menderes University

Brief Summary

This study aimed to investigate gingival crevicular fluid (GCF) and serum levels of LRG, interleukin (IL)-6 and tumor necrosis factor (TNF)-α in patients with periodontitis before and after non-surgical periodontal treatment.

Detailed Description

Twenty-five stage 3 periodontitis and twenty-five periodontally healthy individuals were enrolled in the study. Clinical periodontal measurements were recorded; periodontitis patients received non-surgical periodontal treatment, and GCF and serum samples were obtained at baseline and at 6 weeks after treatment. LRG, IL-6 and TNF-α were determined by ELISA.
