In dental anatomy, 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 .
Gingival sulcus at neck of mammalian tooth Pollen grains of Cercis are sulcate, with reticulate surface. Rotating image of human brain, illustrating the lateral sulcus in the brain . In biological morphology and anatomy , a sulcus ( pl. : sulci ) is a furrow or fissure ( Latin fissura , pl. : fissurae ).
Tobacco smoking impairs phagocytic and chemotactic activities of leukocytes [17] and impedes wound healing, [18] specifically by affecting gingival blood flow. [19] [20] Cigarette smokers are more likely to experience destruction of the alveolar bone and periodontal ligament and are at a higher risk of developing periodontal disease. [21] [22]
The oral epithelium (E) exists on the other side of the free gingival margin. In dental anatomy, the sulcular epithelium is that epithelium which lines the gingival sulcus. [1] It is apically bounded by the junctional epithelium and meets the epithelium of the oral cavity at the height of the free gingival margin.
Gingival retraction or gingival recession is when there is lateral movement of the gingival margin away from the tooth surface. [1] [2] It is usually termed gingival retraction as an intentional procedure, and in such cases it is performed by mechanical, chemical, or electrical means in order to perform certain dental surgery procedures.
Free gingival autograft is one of the more common techniques used for a gingival recession in areas of inadequate attached gingiva in the mandibular anterior region. [10] Conversely, coronally repositioned flaps for the treatment of gingival recession will lead to decreased vestibular depth which may impact oral hygiene or denture retention. [9 ...
In about half of individuals, it is demarcated from the adjacent, attached gums by a shallow linear depression, the free gingival groove. This slight depression on the outer surface of the gum does not correspond to the depth of the gingival sulcus but instead to the apical border of the junctional epithelium.
Gingival sulcus, the space between a tooth and surrounding tissue; Gluteal sulcus, the horizontal crease in humans and certain other primates where the lower end of the buttocks join the thigh; Sulcus (morphology), a groove, crevice or furrow in medicine, botany, and zoology; Sulcus (neuroanatomy), a crevice on the surface of the brain
