Project Abstract

This project aims to investigate the relationship between salivary antioxidant levels and the presence of oral potentially malignant disorders (OPMDs). OPMDs are a group of conditions that have an increased risk of transforming into oral cancer, making their early detection and management crucial for improving patient outcomes. Oxidative stress has been implicated in the pathogenesis of OPMDs, and the evaluation of salivary antioxidant levels may provide valuable insights into the underlying mechanisms and potential biomarkers for these disorders. Oral cancer is a significant global health concern, with an estimated 377,700 new cases and 177,400 deaths reported worldwide in 2020. OPMDs, such as leukoplakia, erythroplakia, and oral submucous fibrosis, are recognized as precursor lesions that can progress to oral cancer if left untreated. Early detection and management of these conditions are essential to prevent the development of oral cancer and improve patient prognosis. However, the assessment of OPMDs often relies on visual examination and biopsy, which can be subjective and invasive. This project will explore the potential of salivary antioxidant levels as a non-invasive biomarker for the evaluation of OPMDs. Salivary analysis has emerged as a promising approach in recent years, as it can provide information about the local and systemic health status without the need for invasive procedures. Antioxidants play a crucial role in maintaining the balance between oxidants and antioxidants, and their levels in saliva may reflect the overall oxidative stress status in the oral cavity. The study will involve the recruitment of patients with clinically diagnosed OPMDs and a control group of healthy individuals. Saliva samples will be collected from all participants, and the levels of various antioxidants, such as superoxide dismutase, catalase, glutathione peroxidase, and total antioxidant capacity, will be measured using appropriate biochemical assays. The data will be analyzed to investigate the differences in salivary antioxidant levels between the OPMD group and the control group, as well as the potential correlation between salivary antioxidant levels and the severity or progression of the oral lesions. The findings of this project may have significant implications for the early detection and management of OPMDs. If salivary antioxidant levels are found to be altered in patients with OPMDs, this non-invasive biomarker could be incorporated into the diagnostic and monitoring protocols for these conditions. This information could assist clinicians in making more informed decisions regarding patient management, potentially leading to earlier intervention and improved patient outcomes. Furthermore, the insights gained from this study may contribute to a better understanding of the underlying mechanisms involved in the pathogenesis of OPMDs. By elucidating the role of oxidative stress and antioxidant imbalance in the development of these conditions, the findings may pave the way for the development of targeted therapeutic strategies or preventive interventions. In conclusion, this project aims to evaluate the potential of salivary antioxidant levels as a non-invasive biomarker for the assessment of OPMDs. The results of this study could have significant implications for the early detection, management, and understanding of these potentially malignant oral disorders, ultimately improving the overall health and well-being of affected individuals.
