Evaluation of role of trace elements in oral submucous fibrosis patients: A study on Gujarati population.

Introduction: Oral submucous fibrosis (OSMF), a precancerous condition, is highly prevalent in the Indian subcontinent. Among many trace elements, copper and iron are required for the functioning of numerous enzymes. The biochemical alterations of these trace elements in the serum of patients with premalignant conditions can help in determining the staging of the disease, its appropriate treatment and as an indicator for prognosis.
