Periodontitis is a chronic inflammatory disease that is known to have the characteristics of destructed periodontal tissue. Anti-oxidant and anti-inflammatory effects of mulberry leaves in periodontal tissue is not well known until now. We investigated the effects of n-butanol extract of mulberry leaves on the lipopolysaccharide (LPS)-induced proinflammatory cytokines, such as $IL-1{\beta}$, IL-6, IL-8 and modulates osteogenic differentiation in periodontal ligament cells. The expression levels of Runx2, ALP and mRNA were increased by n-butanol extract of mulberry leaves at the concentration of $100{\mu}g/ml$ in periodontal ligament cells. n-Butanol extract of mulberry leaves extract reduced the range of pathophysiological processes, such as inflammation and increase in the level of osteogenic-related genes. These findings suggest that n-butanol extract of mulberry leaves has therapeutic effects on periodontitis and periodontal tissue regeneartion.
