Dentinogenesis

Dentinogenesis is a two-phase sequence of dentin formation
Collagen is formed and calcified
The next layer of prevention is formed
Dentinogenesis is not a continuous process, period of rest and accentuation is denoted by incremental lines
Dentinogenesis becomes at the cusp tips after the odontoblasts have differentiated

Dentinogenesis Steps:

Differentiation of odontoblast due to the involvement of fibronectin, decorin, laminin, and chondroitin sulfate
TGF, IGF & BMP are released from inner enamel epithelium
Taken up by pre odontoblast
The shape of the odontoblast changes from ovoid to a columnar shape
Length of odontoblast increases upto 40pm
Proline is released into the extracellular collagenous matrix of the prevention
Proteins get involved in mineralization
Alkaline phosphatase present in matrix vesicles increases the concentration of phosphates
This combines with calcium and forms apatite crystals
As a result of matrix formation in this way, the odontoblast process lengthens Thus prevention is formed
Each increment of prevention is formed and gets calcified than the next increment of presenting forms the Rate of dentin formation
