In the spine, similar fibres join the intervertebral disc to the adjacent vertebrae. [3] Each fibre is accompanied by an arteriole and one or more nerve fibres. [4] Scottish anatomist William Sharpey described them in 1846, although they were also referred to as the claviculi of Gagliardi after Domenico Gagliardi who described them in 1689. [5]
Sharpey fibers are part of the principal collagenous fibers of the periodontal ligament embedded in the cementum and alveolar bone to attach the tooth to the alveolus. [ 3 ] If cementum can be observed on teeth, it can imply that the roots are exposed, showing that the clinical crown (the exposed part of the tooth) is bigger than the anatomical ...
Principal fibers other than the alveolodental ligament are the transseptal fibers. All these fibers help the tooth withstand the naturally substantial compressive forces that occur during chewing and remain embedded in the bone. The ends of the principal fibers that are within either cementum or alveolar bone proper are considered Sharpey fibers.
The formative role of the dental follicle starts when the crown of the tooth is fully developed and just before tooth eruption into the oral cavity. [2]Although tooth eruption mechanisms have yet to be understood entirely, generally it can be agreed that many factors, together, affect the tooth eruption process which is why it is very difficult to differentiate the causes and effects.

In animal tooth development, cementogenesis is the formation of cementum, one of the three mineralized substances of a tooth.Cementum covers the roots of teeth and serves to anchor gingival and periodontal fibers of the periodontal ligament by the fibers to the alveolar bone (some types of cementum may also form on the surface of the enamel of the crown at the cementoenamel junction (CEJ)).
The fact that these structures resemble the fibrillar component of elastic fibers must be emphasized. [3] The oxytalan system's histological appearance is distinguished by fiber ramifications and anastomoses. [4] The periodontal membranes of all human teeth, as well as those of monkeys, rats, guinea pigs, and mice, contain oxytalan fibers. [5] [6]
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 .
