Assessment of Immunohistochemical Expression of Lipid Peroxidation Marker 4-hydroxynonenal in Oral Lichen Planus – A Retrospective Study

These oxidative modifications suggest underlying pathophysiological changes primarily localized to the basal cell layer and the epithelial-connective tissue interface in LP tissues. Further research is needed to explore the role of OS across different clinical and histopathological variants of LP, to enhance early prediction of malignant transformation.
