Introduction: Osteopontin (OPN) is recognized as a potent biomarker of Oral lichen planus (OLP) because of vital role in inflammation and repair process. The aim of present study is assessment of OPN in OLP in comparison with healthy controls (HC).
Material and Methods: To explore salivary levels of OPN, a group of 20 subjects with OLP were compared with 20 HC. Salivary OPN levels was measured by enzyme-linked immunosorbent (ELISA) assay.
Results: Results indicated elevated OPN levels in lesion size < 1 cm compared with 1 - 3 cm lesion size of OLP (p= 0.02). In contrast, we did not find a significant difference in OPN expression level in saliva from OLP patients and healthy controls (P = 0.96).
Discussion: The above results suggest that maybe OPN may serve as a potential biomarker for the monitoring of repair process in OLP.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
