periodontitis were significantly higher than those in healthy
people, suggesting a positive correlation between MMP9 and
periodontitis development. The occurrence of periodontal

inflammation is also closely associated with oxidative stress.
For instance, excessive reactive oxygen species produced by
periodontal inflammation can aggravate the inflammatory
response and activate osteoclasts, resulting in alveolar bone
resorption in patients with periodontitis. Furthermore,
MMP9, as a key gene regulating oxidative stress, can affect
the differentiation process of osteoclasts, aggravate the
inflammation of periodontal tissue, and induce the further
22
absorption of periodontal supporting tissues. Another
key target, ESR1, exerted the best binding effect with
8-isopentenyl-kaempferol. Genetic polymorphisms involved
in estrogen activity may contribute to women’s susceptibility
