Assessment of Oxidant-Antioxidant Status and Stress Factor in Recurrent Aphthous Stomatitis Patients: Case Control Study.

Introduction: Despite its vast occurrence, the aetiology of Recurrent Aphthous Stomatitis (RAS) still remains unknown and its aetiology is multifactorial. The factors believed to be associated with the aetiology of RAS, may disturb the equilibrium of oxidant-antioxidant status of the organism and may accelerate the formation of free radicals, resulting in Oxidative Stress (OS). Psychological stress is believed to act as a triggering factor or modifying factor for RAS.
