An epiphyseal line is an epiphyseal plate that has become ossified. [1] The process of it forming from an epiphyseal plate is named epiphyseal closure . [ 2 ] In adult humans, it marks the point of fusion between the epiphysis and the metaphysis .
Dental work performed mostly in UK/Europe in last half of 20th Century. Tooth development is the complex process by which teeth form from embryonic cells, grow, and erupt into the mouth. Although many diverse species have teeth, non-human tooth development is largely the same as in humans.
A study on rats suggests that the three-dimensional structure of Sharpey's fibres intensifies the continuity between the periodontal ligament fibre and the alveolar bone (tooth socket), and acts as a buffer medium against stress. Sharpey's fibres in the primary acellular cementum are mineralized fully; those in cellular cementum and bone are ...
Dental caries (cavities), described as "tooth decay", is an infectious disease which damages the structures of teeth. [43] The disease can lead to pain, tooth loss, and infection. Dental caries has a long history, with evidence showing the disease was present in the Bronze, Iron, and Middle ages but also prior to the neolithic period. [44]
[3] [4] Between the epiphysis and diaphysis (the long midsection of the long bone) lies the metaphysis, including the epiphyseal plate (growth plate). During formation of the secondary ossification center, vascular canals (epiphysial canals) stemming from the perichondrium invade the epiphysis, supplying nutrients to the developing secondary ...
The dental canaliculi (sometimes called dentinal tubules) are the blood supply of a tooth. [4] Odontoblast process run in the canaliculi that transverse the dentin layer and are referred as dentinal tubules. [5] The number and size of the canaliculi decrease as the tubules move away from the pulp and toward the enamel or cementum.

Synostosis (from Ancient Greek συν- (syn-) 'together' and ὀστέον (ostéon) 'bone'; plural: synostoses) is fusion of two or more bones.It can be normal in puberty (e.g. fusion of the epiphyseal plate to become the epiphyseal line), or abnormal.
