Malondialdehyde as a Marker of Oxidative Stress in Periodontitis Patients.

Background: Periodontology is a fast-evolving field with newer insights into traditional periodontal diagnosis. Advances in periodontal disease diagnostic research are moving toward methods whereby periodontal risk can be identified and quantified by objective measures such as biomarkers.

Objectives: The aim of this study was to evaluate malondialdehyde (MDA) levels in whole saliva of patients with chronic periodontitis.
