Leucin-rich alpha2 Glycoprotein (LRG): A Novel Acute Phase Protein Related With Stage 3 Periodontitis

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.

Study Overview

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.
