marginal gingiva

gingiva /gin·gi·va/ (jin´jĭ-vah) (jin-ji´vah) pl. gin´givae   [L.] the gum; the mucous membrane, with supporting fibrous tissue, covering the tooth-bearing border of the jaw.gin´gival

---

alveolar gingiva  the portion covering the alveolar process.

areolar gingiva  the portion attached to the alveolar process by loose areolar connective tissue, lying beyond the keratinized mucosa over the alveolar process.

attached gingiva  the portion that is firm, resilient, and bound to the underlying cementum and alveolar bone.

free gingiva  the portion of the gingiva that surrounds the tooth and is not directly attached to the tooth surface.

marginal gingiva  the portion of the free gingiva localized at the labial, buccal, lingual, and palatal aspects of the teeth; gingival margin.

[mär′jənəl]

Etymology: L, margo, margin, gingiva, gum

the uppermost part of the free gingiva. It overlaps the neck and base of the crown of the tooth.

gingiva(e)

(jin´jiv),
n/n.pl the fibrous tissue that immediately surrounds the teeth. Colloquial term is gums.

gingiva, adequate attached (AAG),

n the amount of attached gingival tissues needed to prevent recession of the gingival tissues.

gingivae, attached,

n the portion of the gingivae extending from the free gingival groove, which demarcates it from the marginal (free) gingivae, to the mucogingival junction, which separates it from the alveolar mucosa. This tissue is firm, dense, stippled, and tightly bound down to the underlying periosteum, tooth, and bone.

gingivae, attached, extension,

n See extension, gingiva, attached.

gingiva, detached by calculus,

n the recession and ultimate disconnection of gingival tissue from tooth sur-faces that occurs as the result of the presence of large amounts of calculus.

Vestibule and vestibular gingivae of oral cavity. A, Maxilla. B, Mandible.

gingivae, erythemic

n.pl the unusually red gingival tissue that may be caused by either inflammation or excessive blood in the tissue. The condition may occur as a result of excess vitamin A.

gingivae, free,

n.pl an older term for the unattached coronal portion of the gingiva that encircles the tooth to form the gingival sulcus. More commonly called marginal gingiva.

gingivae hyperplasia,

n.pl See hyperplasia, gingival, Dilantinx.

gingiva, inadequate attached (IAG),

n a condition in which the amount of attached gingival tissues in a surveyed area is less than 1 mm, which may result in gingival recession and other periodontal conditions.

gingiva, interdental,

n (interproximal gingiva[e]), the soft supporting gingival tissue, consisting of prominent horizontal collagen fibers, that normally fills the space between two contacting teeth.

Interdental gingiva.

gingiva, interproximal,

n See gingiva, interdental.

gingiva, lymphatic drainage of,

n the lymphatic drainage that follows the course of the gingival blood supply; i.e., from the lymphatic vessels on the gingival side of the periosteum of the alveolar process to the lymphatic vessels in the periodontal membrane to vessels connecting into the alveolar bone.

gingiva, marginal,

n the free gingiva at the labial, buccal, lingual, and palatal aspects of the teeth.

gingivae, microscopic appearance of,

n.pl the stratified squamous epithelium that varies in degree of keratinization and overlies the lamina dura of connective tissue with interspersed blood vessels and nerves. Rete pegs of epithelium project downward into the connective tissue corium, except from the base of sulcular epithelium. The gingival fiber apparatus is also present.
