Cap Stage:

Cap Stage of Tooth Development

A- Oral Epithelium

B- Dental Lamina

C- Developing tooth germ

     C1- Cap shaped Enamel organ -

                              C1 a-  Outer Enamel Epithelium( a  layer of cuboidal cells)

                              C1 b- Stellate reticulum -Central star shaped cells    

                              C1 c- Inner enamel epithelium( tall columnar cells lining the                                                                             concavity of the enamel organ                                                  

     C2- Dental Papilla- Condensation of ectomesenchymal cells adjacent to the inner enamel  epithelium.

     C3- Dental Sac/Follicle- Ectomesenchymal cells that surround the dental papilla and the enamel   organ.
