Dental anatomy is a field of anatomy dedicated to the study of human tooth structures. The development, appearance, and classification of teeth fall within its purview. (The function of teeth as they contact one another falls elsewhere, under dental occlusion.) Tooth formation begins before birth, and the teeth's eventual morphology is dictated
Dental anatomy is dedicated to the study of tooth structure. The development, appearance, and classification of teeth fall within its field of study, though dental occlusion, or contact between teeth, does not. Dental anatomy is also a taxonomic science as it is concerned with the naming of teeth and their structures. This information serves a ...
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.
This layer, along with the inner enamel epithelium, is responsible for the tooth enamel formation. It is a part of the dental (enamel) organ. Stratum intermedium stores glycogen. It is absent in the part of the tooth germ that outlines the root portions of the tooth which does not form enamel.
As the cells of the reduced enamel epithelium degenerate, the tooth is revealed progressively with its eruption into the mouth. The degeneration of reduced enamel epithelium also mediates the initial epithelial attachment to the tooth, which is called the junctional epithelium. The reduced enamel epithelium consist of: Inner enamel epithelium
Their innermost layer consists of conical cells, which at their most young inner-end cut off an enamel-like cuticula. Plate-shaped ceratodontes occur among some mammals , who lost their osseous teeth through the process of evolution , but whose developmental leftovers can still be observed in their jaws during their embryonic state.
A tooth (pl.: teeth) is a hard, calcified structure found in the jaws (or mouths) of many vertebrates and used to break down food.Some animals, particularly carnivores and omnivores, also use teeth to help with capturing or wounding prey, tearing food, for defensive purposes, to intimidate other animals often including their own, or to carry prey or their young.
As the dental pulp is a highly vascularised and innervated region of the tooth, it is the site of origin for most pain-related sensations. [12] The dental pulp nerve is innervated by one of the trigeminal nerves, otherwise known as the fifth cranial nerve. The neurons enter the pulp cavity through the apical foramen and branch off to form the ...
