enamel
The enamel organs gradually loose their connection with the dental lamina because the mesenchyme proliferates into their necks, which distintegrate to form separate nests of epithelial cells. As result the tooth germs are isolated absolutely.
With the further development of the isolated tooth germs, the components of the tooth develop in them in such a manner that the opithelial cells give rise to the enamel, the mesenchymal tissue of the papilla gives origin to the dentine and the pulp, while the mesenchyme initially investing the enamel organ as the dental sac gives rise to the cement and the root sheath.HL7 training helps in integration.
