When Does Bell Stage occur |
weeks 11 and 12 |
|
|
What happens in the bell stage |
Proliferation, differentiation and morphogenesis but mostly differentiation |
|
|
Stages Of Bell stage |
1. Enamel organ 2. Stellate Reticulum 3. Stratum Intermedium 4. Inner Enamel Epithelium |
|
|
Enamel Organ |
Outer enamel epithelium protective barrier for enamel organ, outer cuboidal cells of enamel organ |
|
|
Stellate Reticulum |
Supports the protection of enamel matrix More outer star shaped cells |
|
|
Stratum Intermedium |
Support the production of enamel matrix the Nurse maids |
|
|
Inner Enamel Epithelium |
Will differentiate into ameloblast that form enamel matrix |
|
|
What are the Connective tissue cells |
1. Outer cells of dental papilla 2. Inner cells of dental Papilla 3. Dental Sac |
|
|
What is the outer cells of dental papilla |
Will differentiate into odontoblasts that form dentin matrix |
|
|
What is the inner cells of dental papilla |
Will differentiate into pulp Inner cell mass of the dental papilla |
|
|
Dental Sac |
will produce or differentiate into cementum PDL and Alveolar bone |
|
|
3 types of tooth eruption |
1. pre-function (active) 2. Functional (active) 3. Passive eruption |
