Abstract: BACKGROUND: Stem cells from human exfoliated deciduous teeth originate from naturally replaced deciduous dental pulp. They have the advantages of non-invasive sampling, self-renewal ability, multidirectional differentiation potential, low immunogenicity, closer to embryonic characteristics and no violation of ethical requirements, and are a more ideal source of seed cells. 
OBJECTIVE: To review the ability of stem cells from human exfoliated deciduous teeth in promoting the regeneration of teeth, periodontal and jawbone tissues, as well as their research progress in the treatment of oral and non-oral diseases. 
METHODS: Computers were used to search PubMed, CNKI, and WanFang databases. The Chinese and English search terms were “human deciduous tooth pulp stem cells, regeneration.” A total of 96 articles were searched, and the articles were screened based on inclusion and exclusion criteria. Finally, 52 articles were included for review. 
RESULTS AND CONCLUSION: Stem cells from human exfoliated deciduous teeth have advantages over dental pulp stem cells, dental follicle stem cells, and bone marrow mesenchymal stem cells in the regeneration of teeth, periodontal and jawbone tissues. Stem cells from human exfoliated deciduous teeth have significant therapeutic effects on oral diseases including periodontitis, temporomandibular arthritis, and Sjogren’s syndrome. Stem cells from human exfoliated deciduous teeth have shown good therapeutic effects on non-oral diseases, including neurological, digestive, cardiovascular, urinary, immune, endocrine, respiratory, and psychiatric disorders. 

Key words: stem cell from human exfoliated deciduous tooth, dental follicle stem cell, tissue regeneration, oral disease, non-oral disease, treatment, engineered stem cell
