Dental pulp stem cell (DPSC), with a high capacity of multidirectional differentiation, is the key and preferred cell in the study of dental pulp and dentin regeneration. The effect of trace elements on the differentiation of DPSC is one of the research hotspots in the field of oral tissue engineering in recent years. Trace elements have a wide range of physiological and biochemical functions. It can directly regulate the differentiation, migration and proliferation capacity of DPSC, while can indirectly affect the differentiation of DPSC by exerting antibacterial and immune function regulation or changing the physical and chemical properties of the scaffold material. To clarify the role of trace elements in the differentiation of DPSC can provide more reference for the realization of pulp and dentin regeneration. This paper will review the recent research progress on the effects of relevant trace elements on the differentiation of DPSC into odontogenesis and angiogenesis.
