Abstract

Aim: Periodontitis is characterized by chronic infection and inflammation in periodontal tissues leading to destruction of dental support tissues. Acute-phase proteins are effective markers for the identification and evaluation of inflammatory diseases including periodontitis. Orosomucoid (ORM) is an acute-phase plasma protein, also called alpha-1-acid glycoprotein, which is inflammation sensitive. The aim of this study was to evaluate and compare the salivary levels of ORM and C-reactive protein (CRP) in individuals with/withoutperiodontal disease.
Material and Methods: A total of 90 subjects were divided into two groups of 45 patients each; periodontally healthy and chronic periodontitis. Saliva samples were collected, and clinical periodontal parameters and salivary flow rates were evaluated at baseline. The ORM and CRP levels in the saliva were analyzed with enzyme-linked immunosorbent assay.
Results: The periodontal clinical parameters were significantly higher in the chronic periodontitis group when compared to those of the healthy controls (P0.05). However, the CRP and ORM levels in the saliva were significantly higher in the chronic periodontitis patients than in the healthy controls (P
