Oral cancer is a major global health concern and poses a challenge to diagnostic and therapeutic aspects of healthcare services. Various oral lesions like leukoplakia, erythroplakia, lichen planus and oral submucus fibrosis categorized as orally potential malignant disorders have shown increased incidence of malignant transformation. Free radicals are highly reactive chemical species with capacity to damage nucleic acids, proteins and lipids and bring about changes of clinical significance. Antioxidants help in scavenging these free radicals and prevent disease progression. Naturally occurring phytochemicals play an important role in preventing oxidative stress and protect the cells from damage by free radicals.
