sulcus

 [sul´kus] (L.)
a groove or furrow; used in anatomic nomenclature to designate a linear depression, especially one of the cerebral sulci.
basilar sulcus a groove in the midline of the anterior surface of the pons, lodging the basilar artery.
calcarine sulcus a sulcus of the medial surface of the occipital lobe, separating the cuneus from the lingual gyrus.
central sulcus fissure of Rolando.
cerebral sulci the furrows on the surface of the brain between the gyri (see gyrus).
Cerebral sulci, showing some major ones on the superolateral surface of the left cerebral hemisphere. From Dorland's, 2000.
collateral sulcus collateral fissure.
sul´ci cu´tis fine depressions of the skin between the ridges of the skin.
gingival sulcus the space between the surface of the tooth and the epithelium lining the free gingiva.
hippocampal sulcus hippocampal fissure.
posterior median sulcus posterior median fissure.

gin·gi·val sul·cus

[TA]
the space between the surface of the tooth and the free gingiva.

sul·cus

, gen. and pl. sulci (sŭl'kŭs, -sī)
1. One of the grooves or furrows on the surface of the brain, bounding the several convolutions or gyri; a fissure.
See also: fissure
2. Any long, narrow groove, furrow, or slight depression.
See also: groove
3. A groove or depression in the oral cavity or on the surface of a tooth.
4. The healthy space between the marginal gingiva and a tooth; a space not exceeding 3 mm is considered healthy.
Synonym(s): gingival sulcus.
[L. a furrow or ditch]

gin·gi·val sul·cus

(jin'ji-văl sŭl'kŭs) [TA]
Space between tooth surface and free gingiva.

Resistance indicates that the bottom of the gingival sulcus has been reached.
(4,5) In this article, we describe a case of multiple oronasal fistulas involving the anterior gingival sulcus without palatal involvement.
Toothbrushes properly serve two purposes: to remove foodstuffs and bacteria-laden plaque from tooth surfaces and to clean and stimulate the gingival sulcus, the edge of the gum, which encircles each tooth.
A momentary trauma is seen in the region of junctional epithelium and connective tissue of gingival sulcus with all retraction methods.
The vertical incisions were connected by one sulcular, which was performed in the gingival sulcus of the affected tooth (Figure 2).
As the bacteria challenge increases, an enhanced permeability of the small blood vessels of the subgingival plexus occurs resulting in an increased neutrophil migration through the junctional epithelium and into the gingival sulcus. Interestingly, activated neutrophils may secrete a proteinase (neutrophil proteinase 3) which was shown to activate human oral epithelial cells through [PAR.sub.2], inducing IL-8 and monocyte chemoattractant protein-1 production [17].
Accurate record of finish line can be achieved when gingival sulcus is widened enough in order to provide access for impression material to reach the subgingival margins.16-17 Three principle methods are existing for soft tissue retraction including mechanical, chemo-mechanical and electrosurgical.18-21 The chemo-mechanical technique is doubtless the most extensively used but it is time consuming and can lead to postoperative discomfort, inflammation and marginal recession.20
* Establish gingival sulcus for easy periodontal disease control (elimination of pocket).
(3) Bacteria in the gingival sulcus of a patient with gingivitis can invade the bloodstream and affect the homeostatic control of blood glucose levels.
The GCF samples were collected by placing a microcapillary pipette at the entrance of the gingival sulcus, gently touching the gingival margin [23].
Thus, there is a transformation of the gingival sulcus into a periodontal pocket creating an area where plaque removal becomes impossible.
