Tooth development begins at week 6 in utero, in the oral epithelium. The process is divided into three stages: Initiation; Morphogenesis and; Histogenesis [2]; At the end of week 7 i.u., localised proliferations of cells in the dental laminae form round and oval swellings known as tooth buds, which will eventually develop into mesenchymal cells and surround the enamel organ.
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 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]
Histologic slide showing a tooth bud. A: enamel organ B: dental papilla C: dental follicle. The tooth germ is an aggregation of cells that eventually forms a tooth. [2] These cells are derived from the ectoderm of the first pharyngeal arch and the ectomesenchyme of the neural crest.
The bud stage progresses to the cap stage when the epithelium forms the enamel organ. The ectomesenchyme cells condense further and become dental papilla. Together the epithelial enamel organ and ectomesenchymal dental papilla and follicle form the tooth germ. The dental papilla is the origin of dental pulp.
The outer enamel epithelium, also known as the external enamel epithelium, is a layer of cuboidal cells located on the periphery of the enamel organ in a developing tooth. This layer is first seen during the bell stage. The rim of the enamel organ, where the outer and inner enamel epithelium join is called the cervical loop.
Openclipart, also called Open Clip Art Library, is an online media repository of free-content vector clip art.The project hosts over 160,000 free graphics and has billed itself as "the largest community of artists making the best free original clipart for you to use for absolutely any reason".
The enamel knot is a signaling center of the tooth that provides positional information for tooth morphogenesis and regulates the growth of tooth cusps.The enamel knot produces a range of molecular signals from all the major signaling families, such as Fibroblast Growth Factors (FGF), Bone morphogenetic proteins (BMP), Hedgehog (Hh) and Wnt signals.
