Oxidative Stress Markers Evaluation Before and After Periodontal Treatment of Diabetics Type 2 Patients With Generalized Chronic Periodontitis and Healthy Periodontium
Abstract Diabetes mellitus and periodontal diseases are both chronic inflammatory disorders that have a major impact on the health and well being of millions of individuals worldwide.
Periodontal diseases are among the most common diseases in humans, therefore, if the presence of periodontal diseases plays any role in overall systemic health, the public health impact may be substantial.
An important factor that can be involved in the progression of the periodontal disease is the production of Reactive Oxygen Species (ROS).
The imbalance between oxidative stress induced by ROS and the concentrations (or activity) of the antioxidant may result in tissue damage.
The ROS induce the activity of lipid peroxidation-Tbars, myeloperoxidase (MPO), peroxidase and arginase, whose mechanisms reflect the severity of the periodontal disease and it may offer the basis for a patient specific diagnostic test for periodontitis and could have therapeutic significance.
The aim of this study is to investigate quantitatively the levels of oxidative stress markers (Myeloperoxidase, Peroxidase, Lipid Peroxidation and Arginase) in saliva and in gingival crevicular fluid (GCF) of diabetes type 2 subjects with generalized chronic periodontitis and periodontally healthy individuals, and systematically healthy individuals with generalized chronic periodontitis and periodontally healthy individuals, before and after periodontal treatment.
Unstimulated whole saliva will be collected for 5 min as well as GCF of 25 diabetes type 2 with generalized chronic periodontitis, 25 diabetes type 2 periodontally healthy individuals as controls, 25 systematically healthy individuals with generalized chronic periodontitis and 25 periodontally healthy individuals before and after treatment.
The following clinical parameters will be evaluated: probing pocket depth, probing attachment level, plaque index and the gingival index.
The activity of stress markers in saliva and GFC will be analyzed by spectrophotometry.
Adequate statistical analysis will be carried out with a p-value set at p < 0.05.
