Evaluation of Plasma Isoprostane in Patients with Oral Lichen Planus.

Statement Of The Problems: Lichen planus is a chronic inflammatory disease. Free radicals and reactive oxygen species play important roles in pathogenesis of oral lichen planus (OLP). Isoprostanes show oxidative stress and are formed by free-radical mediated lipid peroxidation of arachidonic acid and cell membrane phospholipids.

Oxidative stress factors and C-reactive protein in patients with oral lichen planus before and 2 weeks after treatment.

Objectives: Oral lichen planus (OLP) is an inflammatory disease with an unknown origin. Oxidative stress is suspected to play a role in its pathogenesis. The aim of this study was to evaluate serum levels of oxidative stress factors and C-reactive protein in patients with OLP.
