According to the study results, salivary levels of IL-1β (80.86 ± 34.3 рg/mL), IL-6 (26.89 ± 10.34 рg/mL), and TNF-α (11.48 ± 6.58 рg/mL) in OLP patients were significantly higher compared to those in healthy controls (30 ± 10.8 pg/mL, 14.06 ± 6.22 pg/mL, and 5.55 ± 3.65 рg/mL, respectively) (Figure 1). Here, IL6 is linked to oral lichen planus.
