The intensity of free radical processes and chaperone activity in the saliva of patients with type 2 diabetes.

Introduction: Saliva is a clinically informative biological fluid that contains many biomarkers, allowing multiple analyses to be performed.

Aim: The objectives of this study were the assessment of the serum and saliva levels of biochemical parameters and intensity of free radical processes in T2DM patients and the identification of the correlation between certain criteria.

Methods: This case-control study included 40 T2DM patients, which were compared with 40 healthy individuals.

Parameters of Oxidative Stress and Activity of Antioxidant Enzymes in the Saliva of Patients with Type 1 Diabetes Mellitus.

Glucose concentration in the saliva is increased in type 1 diabetes mellitus. This parameter directly correlates with markers of the disease in the blood serum. Increased concentration of 8-oxo-2'-deoxyguanosine (8-OHdG) and diene conjugates, markers of oxidative stress, and reduced activities of superoxide dismutase and catalase were also observed in this pathology.
