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 enamel organ which is differentiated from the primitive oral epithelium lining the stomodeum.
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 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]
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 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 ...

In the tooth bud, regions where enamel formation is completed, the enamel organ gives rise to Hertwig's epithelial root sheath, composed of two epithelial layers derived from the external and internal epithelia. The sheath is irregularly fragmented in time and space as it promotes cementum deposition on the newly formed dentin.
