How is gingival sulcus formed?
Emily Wong How is gingival sulcus formed?
The gingival sulcus is formed by the space between the sulcular epithelium, the junctional epithelium, and the wall of the tooth. The functioning of its different parts is important in the early changes taking place when marginal plaque is accumulating.
What is the clinical significance of the gingival sulcus?
Gingival sulcus: V-shaped crevice that surrounds each tooth, bounded by tooth on one side and epithelium lining free margin of gingiva on the other. Sulcus is ideal for bacteria; it is resistant to the cleaning action of saliva. Gingival fluid (sulcular fluid) is a rich nutrient source for microorganisms.
How does a sulcus become a gingival pocket?
When the tissues at the coronal margin of the sulcus become swollen, which can happen for a number of reasons, a gingival pocket forms. This means that the depth of the sulcus has increased, but the apical base of the sulcus is stationary.
What are the three main parts of the gingival sulcus?
It is divided up into three major sections known as the:
- oral epithelium.
- the sulcular epithelium.
- the junctional epithelium.
What are the boundaries of the gingival sulcus?
The depth of the sulcus (Latin for groove) is bounded by two entities: apically by the gingival fibers of the connective tissue attachment and coronally by the free gingival margin.
What sulcus means?
Definition of sulcus : furrow, groove especially : a shallow furrow on the surface of the brain separating adjacent convolutions.
Where are furcations on maxillary molars?
Maxillary molar mesial furcations are typically located one-third of the distance from the lingual surface and two-thirds of the distance from the buccal surface. This location, combined with the larger lingual embrasure space, makes mesial furcations both easier to locate and treat.

How many sulcus are in the brain?
The five sulci and adjoining gyri selected for investigation. Top: (A) Superior frontal sulcus, (B) Central sulcus, (C) Lateral sulcus, (D) Superior temporal sulcus, and (E) Intra-parietal sulcus.
What is gingival sulcus in anatomy?
Anatomical terminology. The gingival sulcus is an area of potential space between a tooth and the surrounding gingival tissue and is lined by sulcular epithelium. The depth of the sulcus (Latin for groove) is bounded by two entities: apically by the gingival fibers of the connective tissue attachment and coronally by the free gingival margin.
What is the depth of the sulcus in the mouth?
The depth of the sulcus (Latin for groove) is bounded by two entities: apically by the gingival fibers of the connective tissue attachment and coronally by the free gingival margin. A healthy sulcular depth is three millimeters or less, which is readily self-cleansable with a properly used toothbrush or the supplemental use…
