Abstract
BACKGROUND
In the current scenario pathogenesis of majority of the diseases is deeply linked with the oxidative stress, irrespective of its etiology. Enumerable data suggests that reactive oxygen species play a key role in multistage carcinogenesis. Oral submucous fibrosis (OSMF) is considered as a potentially malignant disorder. Its increased incidence over recent years in the Indian subcontinent is a major health concern to oral physicians. However, the role of oxidative stress has not been widely investigated in OSMF.
AIMS
Is to evaluate both antioxidant and oxidant status in OSMF and to compare with controls.
SETTINGS AND DESIGN
Twenty patients and 20 controls of the same age group were enrolled in the study.
SUBJECTS AND METHODS
Five milliliters of blood were collected from each individual and serum was separated. Malondialdehyde (MDA) estimation using thiobarbituric acid (TBA) method, and antioxidant activity (AOA) using principle of TBA reactive substances was done using this serum, with a calorimetric method.
STATISTICAL ANALYSIS USED
Student's t-test and ANOVA test.
RESULTS
The mean serum AOA status was seen to significantly decrease in OSMF patients, as compared to controls (P = 0.013). The increase in mean serum MDA level was highly significant in OSMF patients, as compared to controls (P < 0.001).
CONCLUSION
The disparity between AOA and MDA levels in the patients clearly demonstrates the role of oxidative stress in the disease process. The results also suggest the use of antioxidants in the management of OSMF.
