Free-radical Oxidation and Superoxide Dismutase Activity in Synovial Fluid of Patients with Temporomandibular Disorders
Volume 20, Number 1, 2006,-0001,():
To measure the activity of oxygen free radicals and the level of antioxidant enzyme superoxide dismutase (SOD) in the synovial fluid (SF) of the temporomandibular joints (TMJs) of patients with temporomandibular disorders (TMD). Methods: Thirty-two patients were divided into 3 subgroups: anterior disc displacement with reduction, anterior disc displacement without reduction, and osteoarthrosis. Six healthy volunteers served as controls. A pumping procedure was used to take SF from the superior TMJ space. The concentration of lipid peroxidation products was assessed by means of the thiobarbituric acid reaction, and the level of SOD was assessed with spectrophotometry. Results: SF levels of lipid peroxides (LPO) in the control and patient groups were 0.010 (
