Inhibitory effect of Acer tegmentosum maxim extracts on P. gingivalis LPS-induced periodontitis

•Periodontal therapy is important for improving oral health and averting systemic diseases.•Acer tegmentosum Maxim ameliorated periodontitis through an antibacterial and anti inflammatory activities in animal model.•Acer tegmentosum Maxim could be used as a natural anti-periodontitis agent for the prevention of periodontal disease. Periodontitis disease is a chronic inflammation, and the prevention or treatment of periodontal disease is important for improving oral health and averting systemic diseases.Acer tegmentosum Maxim (ATM) is a type of deciduous tree in Korea. ATM extracts have been traditionally used to treat various dieases. This study investigated the effects of ATM extract on mitigation of periodontitis in vitro and in vivo. The current study investigated whether extracts ofAcer tegmentosum Maxim (ATM) attenuated periodontitis induced by Porphyromonas gingivalis-derived lipopolysaccharide (LPS) in vitro and in vivo. We used a rat model of experimental periodontitis that received oral administration of 1 mg/kg P. gingivalis-derived LPS for 10 days. Periodontitis models was treated with two different dosages of ATM (30 or 100 mg/kg) during the same period of periodontal induction for histological analysis. The results indicated that aqueous ATM extracts effectively ameliorated ligature-induced periodontitis through of the antibacterial, anti-oxidative, and anti-inflammatory activities. These pre-clinical results suggest the need for further studies on the anti-periodontitis effect of ATM in humans. Thus, ATM could be used as a natural anti-periodontitis agent for the treatment of periodontitis.
