Dentinogenesis

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
