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.
How many gingival fibers are there?
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 the three types of gingiva?
Gingiva
- Types of gingivae. Marginal gingiva. Attached gingiva.
- Gingivitis.
- Sources.
What are the functions of gingiva?
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.
Where are gingival fibers located?
Gingival fibers are the connective tissue fibers which are found in the gingival tissue adjacent to the teeth. They aid in holding the gum tissue firmly against the teeth. They are primarily composed of type I collagen, however, type III fibers are also involved. These fibers connect the tooth to the gingival tissue.
What are Sharpey’s fibers?
Sharpey’s fibres (bone fibres, or perforating fibres) are a matrix of connective tissue consisting of bundles of strong predominantly type I collagen fibres connecting periosteum to bone. Each fibre is accompanied by an arteriole and one or more nerve fibres. Scottish anatomist William Sharpey described them in 1846.
What are parts of gingiva?
The gingiva is composed of fibrous tissue covered by mucous membrane that is firmly attached to the periosteum of the alveolar processes of the mandible and maxilla. The lower gingiva includes the mucosa covering the mandible from the gingival-buccal gutter to the origins of the mobile mucosa on the floor of the mouth.
How many types of gingiva are there?
Structure of the Gingiva There are two types of gingiva and several important anatomic regions. Alveolar mucosa – The area of tissue beyond the mucogingival junction. It seems less firmly attached and redder than the attached gingiva.
What is gingival mucosa?
gin·gi·val mu·co·sa. (jinji-văl myū-kōsă) Portion of oral mucous membrane that covers and is attached to necks of teeth and alveolar process of jaws; demarcated from lining mucosa on the facial aspect by a clearly defined line that marks mucogingival junction.
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.
Where do Sharpey’s fibers come from?
Sharpey’s fibres (bone fibres, or perforating fibres) are a matrix of connective tissue consisting of bundles of strong collagenous fibres connecting periosteum to bone. They are part of the outer fibrous layer of periosteum, entering into the outer circumferential and interstitial lamellae of bone tissue.
