The cervical margin of a tooth is the surface above the junction of the crown of the tooth and the root of the tooth. [1]
The cervical loop is the location on an enamel organ in a developing tooth where the outer enamel epithelium and the inner enamel epithelium join. The cervical loop is a histologic term indicating a specific epithelial structure at the apical side of the tooth germ, consisting of loosely aggregated stellate reticulum in the center surrounded by ...
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 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.
The cells are part of the reduced enamel epithelium after enamel maturation and then subsequently undergo apoptosis before or after tooth eruption. [ 2 ] [ 3 ] : 103 These stages occur during the third and final stage of amelogenesis , called the maturation phase.
The Huffington Post reached out to historians across the country to create a list of women who deserve more recognition for their accomplishments.
In animal tooth development, the inner enamel epithelium, also known as the internal enamel epithelium, is a layer of columnar cells located on the rim nearest the dental papilla of the enamel organ in a developing tooth. This layer is first seen during the cap stage, in which these inner enamel epithelium cells are pre-ameloblast cells.
Odontoblasts form approximately 4 μm of predentin daily during tooth development. [ 1 ] During secretion after differentiation from the outer cells of the dental papilla, it is noted that it is polarized so its nucleus is aligned away from the newly formed dentin, with its Golgi complex and endoplasmic reticulum towards the dentin reflecting ...
