Tooth Development

1, 3, 4 - enamel organ
1 - internal cells of the enamel organ
      (these cells will be ameloblsats)

5 - dental follicle
6 - epithelium of oral cavity

Tooth Development

1 - ameloblasts (former external cells of the enamel organ)
2 - enamel
3 - dentine (predentine)
4 - odontoblasts (cells which covered the top of dental papilla)
