Odontoblasts in the area of the traumatized tubules may perish because of the injury,but neighboring undifferentiated mesenchymal cells of the pulp can move to the area and become odontoblasts,forming a type of tertiary dentin,reparative dentin.If the tertiary dentin is formed by existing odontoblasts,it is considered to be reactive dentin.A certain type of tertiary dentin,sclerotic dentin occurs when the odontoblastic processes die and leave the dentinal tubules vacant.Mantle dentin is the first predentin that forms.
