It initiates division and migration of precursor cells to substrate surface followed by addition and cyto-differentiation into odontoblast like cells in zone of coagulated necrosis.
The dental pulp is isolated from the lesion by the defensive response of a mature odontoblast, which produces secondary and reparative dentin in response to external physiological and pathological stimuli.
Bracnhes of this vascular network connects its arterioles and venules under the odontoblast layer and venules leave pulp using the same apical foramen (33,34).
They also noticed the expression of markers of mineralization, suggesting that the material is capable of inducing the differentiation of odontoblast cells, involved in the formation of dentin tissue.
4 The material does not provide close adaptation to dentin, does not promote consistent odontoblast differentiation and has been shown to be cytotoxic in cell cultures; the resultant reparative dentin formation can be characterized by tunnel defects.
On the contrary, our preliminary data strongly suggest that sensory nerve contributes pulp cells and matrix-producing cells of odontoblast lineage to the growing tooth.
Our data showed that ginsenoside Rg1 significantly stimulated DPSCs proliferation and promoted the odontoblast differentiation.
NGF was also characterized as a potent promoter of mineralization during dentin formation and it also promotes in vitro odontoblast differentiation (26).
In Group III, the remaining pulp was permeated by an inflammatory cell infiltration, and the odontoblast layer was discontinuous.
