Study Notes

Tooth Development

The process of tooth development from a few cells in the primitive oral cavity to an erupted tooth with crown and root is called morphodifferentiation.
The unique epithelial tissue that covers the crown of the tooth is called enamel organ.

Enamel Formation

Enamel formation is also known as amelogenesis.
The two main types of cells involved in enamel formation are ameloblasts and ectomesenchyme cells.
Ameloblasts develop from the inner dental epithelium and require communication with ectomesenchyme cells to differentiate.
The principal stages of enamel development are:
- Secretion stage: ameloblasts secrete a unique extracellular matrix containing enamel proteins.
- Maturation stage: ameloblasts secrete a basal lamina on the enamel surface and attach to it.
Disturbances in enamel formation can be caused by genetic or environmental factors.
The composition of enamel during the secretion stage is a unique extracellular matrix containing enamel proteins.
The composition of enamel during the maturation stage is a highly mineralized, hard tissue.
Hydroxyapatite, the mineral found in enamel, has the formula Ca₅(PO₄)₃(OH).

Ameloblasts

Ameloblasts are responsible for the formation of enamel rods during enamel development.
The function of ameloblasts during the secretory stage is to secrete a unique extracellular matrix containing enamel proteins.
The function of ameloblasts during the maturation stage is to secrete a basal lamina on the enamel surface and attach to it.
The term given to the end of the ameloblast cell which lays down the crystals of the enamel matrix is Tomes' process.

Other

The hardest tissue in the body is enamel.
The role of enamel tufts is to anchor the enamel to the underlying dentin.
The role of enamel spindles is to provide a pathway for ions to move through the enamel.
The reduced dental epithelium plays a role in the formation of the enamel organ during tooth development.
