Abstract:

BACKGROUND: Stem cells from the apical papilla are a kind of odontogenic mesenchymal stem cells that can differentiate into odontoblasts under the action of special inducing factors, further forming the root dentin. Restoration and regeneration of pulp-dentin complex is a new clinical strategy for the treatment of pulp and periapical diseases, especially for the retention of young permanent teeth. Directional induction of stem cells from the apical papilla into odontoblasts has gradually become a hot topic in endodontology.

OBJECTIVE: To review the factors related to the differentiation of stem cells from the apical papilla into dontoblasts, in order to provide the research basis for the root development of young permanent teeth and other clinical applications.

METHODS: PubMed, VIP, WanFang and China Journal Full-Text databases were searched for relevant literatures published from January 2013 to December 2019 using the keywords of “SCAP, odontogenic differentiation” in English and Chinese, respectively. Finally, 38 articles were retrieved and summarized, and the remaining 18 articles were further explained of the literature content.

RESULTS AND CONCLUSION: We systematically reviewed the odontogenic differentiation of stem cells from the apical papilla via relevant signaling pathways under specific induction factors, including cytokines, gene transfection, bioactive materials and scaffolds, chemical factors, and physical factors. Seeking for the ideal conditions for the odontogenic differentiation of stem cells from the apical papilla as well as relevant effects and mechanism is very important for the treatment of pulp and periapical disease and for the study on pulp-dentin complex in tissue engineering field.
