Abstract: BACKGROUND: Hypoxia and inflammation usually occur together in many diseases. The microenvironment in which periodontal inflammation occurs is hypoxic. Hypoxia and the hypoxia-inducible factor pathway play a key role in the metabolism of periodontal tissue and alveolar bone.
OBJECTIVE: To explore the role of hypoxia in periodontal inflammation, bone repair and regeneration and the related cellular and molecular mechanisms and to briefly discuss the application of hypoxia mimetic agents in periodontal bone regeneration.
METHODS: PubMed, CNKI and WanFang database were searched for relevant literature published from January 1990 to October 2022. The search words were “hypoxia; hypoxia inducible factor-1α; periodontitis; periodontal; bone; angiogenesis”in Chinese and English, respectively. A total of 49 articles were included for review, based on the content of the articles that were similar or consistent with the topic of the present study.
RESULTS AND CONCLUSION: Hypoxia can cause oxidative stress and aggravate periodontal inflammation. Hypoxia promotes angiogenesis in periodontitis. Hypoxia can promote the proliferation and osteogenic differentiation of periodontal stem cells and promote osteogenesis and osteoclast differentiation. It is helpful to design new therapies for accelerating bone repair and regeneration by enriching the understanding of periodontal tissue and bone regeneration through hypoxic and hypoxia-inducible factor pathways.

Key words: periodontitis, hypoxia, HIF-1 α, hypoxia-inducible factor, bone regeneration, hypoxia mimetic agent, bone metabolism
