Oral submucous fibrosis (OSMF) is a disabling, potentially malignant condition of the oral cavity. The aetiology of OSMF is multifactorial but remains obscure. Although arecanut is considered to be the most important causative agent, responses observed in individuals using arecanut vary in relation to quantity and duration. It is considered that an immunological process is responsible for the pathogenesis of disease. We correlated salivary immunoglobulin A (IgA), salivary immunoglobulin G (IgG) and serum immunoglobulin A (IgA), serum immunoglobulin G (IgG), levels by turbidometric immunoassay. We estimated the levels of total serum protein (TSP) and haemoglobin (Hb) to determine the role of nutritional deficiency. The study population comprised 30 cases of OSMF and 10 controls. Five milliliters of blood and 2 ml of saliva were collected. Quantitative analysis of serum and salivary IgG, IgA was done by turbidometric immunoassay. TSP and Hb were estimated by Biuret and cyanmethaemoglobin methods, respectively. All patients showed significant (P < 0.01) increase in serum and salivary IgG, IgA levels as compared to controls. TSP patients showed significant (P < 0.01) decrease as compared to controls. Results of Hb in patients were not significant. The estimation of immunoglobulin levels is important to support the concept of autoimmune basis. Estimation of TSP and Hb suggests that nutrition has a definite role in OSMF.
