The enamel organ, also known as the dental organ, is a cellular aggregation seen in a developing tooth and it lies above the dental papilla. [1]
The tooth bud (sometimes called the tooth germ) is an aggregation of cells that eventually forms a tooth and is organized into three parts: the enamel organ, the dental papilla and the dental follicle. [3] The enamel organ is composed of the outer enamel epithelium, inner enamel epithelium, stellate reticulum and stratum intermedium. [3]
It is organized into three parts: the enamel organ, the dental papilla and the dental follicle. [27] The enamel organ is composed of the outer enamel epithelium, inner enamel epithelium, stellate reticulum and stratum intermedium. [27] These cells give rise to ameloblasts, which produce enamel and the reduced enamel epithelium.
Enamel can be affected further by non-pathologic processes. Enamel is covered by various structures in relation to the development of tooth: Nasmyth membrane or enamel cuticle, structure of embryological origin is composed of keratin which gives rise to the enamel organ. [18] [19]

The enamel organ → purely the epithelial component; The tissues which have been derived from each of the three components are: The dental follicle → will develop to become the periodontal ligament, the cementum and the alveolar bone; The dental papilla → will develop to become the dental pulp and the dentine; The enamel organ → will ...
The enamel organ is composed of the outer enamel epithelium, inner enamel epithelium, stellate reticulum and stratum intermedium. [2] These cells give rise to ameloblasts , which produce enamel and become a part of the reduced enamel epithelium (REE) after maturation of the enamel.
The enamel cord, also called enamel septum, is a localization of cells on an enamel organ that appear from the outer enamel epithelium to an enamel knot.The function of the enamel cord and the enamel knot is not known, but they are believed to play a role in the placement of the first cusp developed in a tooth.
