clinical applicability of stem cell therapy in dental diseases: a systematic review of available clinical trials

Background: developing cell-based therapeutic methods for differentiating various stem cells into dental tissues could be a revolutionary step toward using cell therapy for dental diseases. in the present study, we systematically reviewed the literature to determine the efficiency of stem cells in treating various dental diseases. materials and methods: using the search words “stem cell” and “dental disease” as well as all their equivalents and similar terms, we performed a literature search in september 2020 in the electronic databases: pubmed, scopus, science direct, web of science, embase, ovid, and google scholar. the investigation was limited to clinical trials written in the english language. results: overall, 22 articles with 400 study patients were found and used for qualitative data synthesis. findings showed that various stem cells with different origins can be used for cell therapy of various dental diseases such as pulp necrosis, traumatic dental injuries, maxillofacial bony defects, impacted third molars, etc. conclusion: stem cell therapy is an efficient method for treating dental diseases. it can regenerate whole dental pulp and may be useful for treating tooth injuries due to trauma.
