Formation of the Dental Hard Tissues Part 3: Cementogenesis Flashcards
What are the types of cementum labelled?
What type of tissue is cementum?
Ectomesenchymal – From Dental Follicle
What is root development driven by?
Root development “driven” by Hertwig’s epithelial root sheath
What is labelled?
How is the root formed part 1?
How is the root formed part 2?
Where is the Hyaline layer and what is its role?
- Between dentine and cemetum
- highly mineralised
- origin - matrix from:
– epithelial cells - enamel matrix proteins
– ? ectomesenchymal cells as well
role:
– Induces cementoblast formation
– cements cementum to tooth
What is the Cementoblast Origin?
Derived from Dental Follicle
What direction do cementoblasts migrate and what do they deposit?
Cementoblasts migrate outwards
Deposit matrix (pre-cementum):
– collagen
– extracellular matrix
how do PDL collagen fibres mineralise?
PDL collagen fibres become trapped in cementum and mineralise
How does enamel matrix proteins lead to Attachment?
How does Enamel matrix proteins in enamel lead to Cementum on enamel surface?
What is labelled and Epithelial proteins placed on a root surface can induce what?
How does Enamel Matrix Derivative applied to the root surface lead to Reattachment?
