type I collagen fibers collected into fiber bundles within the subepithelial connective tissue of the gingiva; they extend from the cementum of the cervix of the tooth, pass over the crest of the alveolus, and insert into the periosteum of the cortical plate of the alveolus.
What are gingival fibers?
The gingival fibers are the connective tissue fibers found in the gingival tissue next to the teeth. They help hold the gum tissue firmly against the teeth. They primarily consist of type I collagen, but type III fibers are also involved.
What are the four gingival fiber groups?
At least six of these gingival fiber groups insert into the cementum of the natural tooth: the dentogingival (coronal, horizontal, and apical), dentoperiosteal, transseptal, circular, semicircular, and transgingival fibers.
What are principal fibers?
The major fiber groups of the functioning periodontium. They attach the tooth to the bone and adjacent teeth.
What is interdental gingiva?
The interdental papilla, also known as the interdental gingiva, is the part of the gums (gingiva) that exists coronal to the free gingival margin on the buccal and lingual surfaces of the teeth.
What are the functions of the Periodontium?
The periodontium functions include supporting the tooth, protecting it against oral microflora, and making the attachment of the tooth to the bone possible. [1] To understand the function of the periodontium even further, we can look at its components function individually.
What are free gingival Fibres?
The free gingival fibers arise from the surface of the cementum in the cervical region and pass into the free gingiva. The attached gingival fibers arise from the alveolar crest and pass into the attached gingiva.
What is gingival ligament?
The gingival fibers are the connective tissue fibers that inhabit the gingival tissue adjacent to teeth and help hold the tissue firmly against the teeth. These fibers, unlike the fibers of the periodontal ligament, in general, attach the tooth to the gingival tissue, rather than the tooth to the alveolar bone.
What are the types of gingiva?
There are two types of gingivae that are clearly recognizable and they are known as the marginal gingiva that is mobile, and the attached gingiva.
What is the function of Sharpey fibers?
In the skull the main function of Sharpey’s fibres is to bind the cranial bones in a firm but moveable manner; they are most numerous in areas where the bones are subjected to the greatest forces of separation. In the spine, similar fibres join the intervertebral disc to the adjacent vertebrae.
What is the function of the gingiva?
Gingival Structure, Function, and the Latest Research The gingiva (or gums) is the tissue that surrounds and protects the teeth and underlying bone. The gingiva is attached to the tooth, forming a seal that protects the underlying bone and helps provide a barrier against infection.
What are alveologingival fibers and dentoperiosteal fibers?
Alveologingival fibers: These fibers extend from the periosteum of the alveolar crest into the gingival connective tissue. These fiber bundles attach the gingiva to the bone. Dentoperiosteal fibers: These fibers extend laterally from the tooth to the periosteum of the alveolar bone. They attach the tooth to the bone.
What are the fibers of the gingival ligaments?
Gingival Ligaments (originate either from cementum or alveolar bone and inserts into gingiva). The principal fiber bundles are arranged into five groups. The alveolar crest fibers originate from the cementum just below the cementoenamel junction (CEJ) and insert at the crest of the alveolar bone socket.
What are the components that invest and support the human tooth?
Besides periodontal ligaments, other components that invest and support the human tooth are cementum, alveolar bone, and part of the gingiva that is facing towards the teeth. The periodontal ligaments are the dense soft connective tissue. Most of the periodontal ligament fibers are present between cementum and the bone lining the tooth socket.
Where are interpapillary fibers located in the gingival tissue?
Interpapillary fibers: These fibers are located coronal to the transseptal fibers connecting the oral and vestibular interdental papillae of posterior teeth. There is a variety of resident cells in the gingival connective tissue, making around 8% of its total volume.
