Bud stage |
(Simultaneous with dental Lamina) 1: round swelling at 10 different points (primary dentition) in each jaw- w/out clear arrangement of cells |
|
|
Cap stage |
3: proliferation of cells (dental papilla) that look like a hollowed cap - becomes the enamel organ. |
|
|
Bell stage |
4: histodifferentiation and histomorphodifferentiation. Enamel organ is bell shaped and most cells are called stellate reticulum |
|
|
Dental Lamina stage |
1 (occurs simultaneously with bud stage): oral epithelium has a basal and surface layer of cells |
|
|
Hertwig's root sheath/ root formation |
Step 5: formed by Union of inner and outer enamel epithelial. Molds shape of the roots. Initiates Dentin formation. |
|
|
What direction do teeth develop? |
Development occurs from tooth buds in the anterior portion of the maxilla and mandible then proceed posteriorly. |
|
|
Enamel organ |
Derived from ectoderm Made by ameoblasts Form the enamel |
|
|
Dental papilla |
Derived from mesenchyme Dentin is synthesized by odontoblasts Pulp is synthesized by mesenchyme cells |
