Abstract: BACKGROUND: Small extracellular vesicles are important components of paracrine pathways. In recent years, the application of small extracellular vesicles in oral tissue regeneration attracted wide attention.  
OBJECTIVE: To review the role and application of small extracellular vesicles in periodontal and pulp tissue regeneration. 
METHODS: PubMed, Web of Science, CNKI and Wanfang databases were searched for relevant articles published in the past ten years. The retrieval MeSH Terms or key words were “small extracellular vesicles, exosomes, pulp stem cells, periodontal regeneration, bone regeneration, pulp regeneration, regenerative endodontics, revascularization” in Chinese and English, respectively. After removal of poorly related, outdated, and duplicate studies by reading the title and abstract, 71 articles were finally included in result analysis.
RESULTS AND CONCLUSION: (1) Small extracellular vesicles were secreted by many kinds of cells, participated in intercellular communication and mediated immune response. Small extracellular vesicles have a great application potential in tissue regeneration. (2) Small extracellular vesicles play an important role in periodontal tissue repair and regeneration. Small extracellular vesicles can regulate periodontal inflammation and promote periodontal ligament and surrounding bone tissue regeneration. (3) Small extracellular vesicles improve dental stem cells to regenerate functional pulp-dentin complexes.

Key words: small extracellular vesicle, exosome, dental stem cell, periodontal regeneration, bone regeneration, pulp regeneration, pulp revascularization, review
