RESUMO
@#Dental caries, trauma, and iatrogenic stimulation can cause damage to the dentin-pulp complex. Preserving the viable pulp and promoting damage repair of the dentin-pulp complex is of great clinical significance at present. In recent years, studies have found that various small molecular compounds can regulate inflammation, promote the migration, proliferation, and differentiation of dental pulp stem cells, promote blood vessel, nerve regeneration and other biological processes by regulating key intracellular signaling pathways and metabolic pathways, and could thereby promote damage repair of the dentin-pulp complex. The objective of this paper is to review recent research on various small molecular compounds used in promoting the repair of dentin-pulp complex.
