oral epithelial cells |
Form enamel organ |
|
|
Mesenchymal cells |
Form Dental papilla |
|
|
Neural crest cells |
Contribute to tooth development migrate into Jaws and intermingle with mesenchymal cellsIntegrate with dental capella and epithelial cellsAlso function in development of salivary glands bone cartilage nerve and muscles |
|
|
dental lamina |
1st sign of tooth formation. begins to function at 6th week of development arises from oral epithelium develops into sheet of epithelial cells leading edge forms 20 buds |
|
|
Successional lamina |
Develops permanent teeth |
|
|
Odontogenesis |
Growth calcification and eruption |
|
|
Bud stage |
Mound growth of epithelial cells surrounded by mesenchymal cells initiation begins from Dental lamina |
|
|
Caps stage |
Bud makes concave surface. Epithelial cells become an animal organs and attach to dental lamina Mesenchymal cells form dental papilla become the pulp tissue surrounding is the dental foliccle. |
|
|
Bell stage |
histodifferentiation: development of different tissues. |
|
|
morphodifferentiation |
development of different forms ameliblast deposit enamel and odontoblasts deposit dentin |
|
|
odontoblasts? |
elongate and become columnar form predentin which becomes dentin after 24 hours. dentogenesis always proceeded amelogenesis |
|
|
Dental sac |
form Cementoblast |
|
|
Stages of AmeloGenesis |
MorphogenesisOrganization and differentiationSecretionMaturationProtection |
|
|
Calcification |
Takes place in the maturation stage enamel Dentin and cementum become calcified hardened by the deposits of calcium or other mineral salts |
|
|
Apposition |
Happens in the maturation stage calcium, salts and minerals deposited tooth structures form in layers enamel, Dentin and cementum. |
