Background: Oral lichen planus is a chronic inflammatory disease with a poorly understood etiology. The role of angiogenesis in the development of different chronic inflammatory diseases is of great concern. Vascular endothelial growth factor (VEGF) is an important regulator of angiogenesis. We aimed to evaluate the serum level of VEGF in patients with oral lichen planus compared with normal individuals and consider its clinical significance.
Methods: In this case-control study, 36 serum samples from patients diagnosed with oral lichen planus admitted to the Oral Medicine Department of the School of Dentistry at Shiraz University of Medical Sciences (14 men, 22 women, mean [±SD] age: 38.8 [±6.07] years) and 23 serum samples from healthy individuals (9 men, 14 women, mean [±SD] age: 38.7 [±4.9] years) were collected. VEGF concentration was measured using the ELISA method. The Mann-Whitney test was used for statistical analysis.
Results: The serum VEGF level was significantly higher in patients with oral lichen planus compared with the healthy controls (112.97 [±63.2] vs. 66.21 [±56.2] ngr/ml, P
