AIM: To investigate the expression of salivary S100A7 levels among patients with oral submucous fibrosis (OSF) and healthy controls.
METHOD: A total number of 60 participants were included in the study (30 OSF cases and 30 healthy controls). Demographic data was collected using a structured baseline questionnaire. Salivary S100A7 levels were quantified using enzyme-linked immunosorbent assay. Data was analyzed using Student t-test. Pearson correlation test was used to evaluate correlation between S100A7 levels and independent variables such as frequency and duration of areca nut use, gutka use, and mouth opening.
RESULTS: The mean value of salivary S100A7 for OSF group was 0.275 ng/ml, whereas mean value of salivary S100A7 for healthy controls was 0.195 ng/ml. Student t-test indicated that there was statistically significantly higher levels of S100A7 in OSF group as compared to healthy controls (p < .001). When the clinical variables of individual groups were analysed, a significant negative correlation was found between salivary S100A7 and duration of areca nut (p = .009) and gutka chewing (p = .03), whereas a significant positive correlation was found for mouth opening (p = .04).
CONCLUSION: OSF presented higher levels of salivary S100A7 levels as compared with healthy individuals and may be used as surrogate measure to identify subjects at risk for OSF.
