junctional epithelium

The junctional epithelium may even become infiltrated with enough leukocytes so that it resembles a microabscess.

This junction has three epithelial types: gingival, sulcular, and junctional epithelium.

It is thought to play an immune role in the junctional epithelium at the gingival crevice in the human mouth.

Teeth treated with scaling and root planing evidenced only long junctional epithelium as the body of scientific evidence shows.

The junctional epithelium, composed of the basal lamina and hemidesmosomes, forms an attachment to the tooth.

The junctional epithelium is that epithelium which lies at, and in health also defines, the base of the gingival sulcus.

Similarly, electron-lucent and electron-dense zones can be seen between enamel of teeth and the junctional epithelium.

Biologic width is the distance established by "the junctional epithelium and connective tissue attachment to the root surface" of a tooth.

In health, the junctional epithelium creates the most coronal attachment of the gum tissue to the tooth at or near the cementoenamel junction.

In gingivitis, inflammation localized to the supracrestal region of the periodontium leads to ulceration of the junctional epithelium.

Healthy gingiva are characterized by small numbers of leukocytes migrating towards the gingival sulcus and residing in the junctional epithelium.

As the original sulcular depth increases and the apical migration of the junctional epithelium has simultaneously taken place, pathosis has occurred.

The supracrestal attachment apparatus is composed of two layers: the coronal junctional epithelium and the more apical gingival connective tissue fibers.

It is apically bounded by the junctional epithelium and meets the epithelium of the oral cavity at the height of the free gingival margin.

Alveolar crest fibers (I): extend obliquely from the cementum just beneath the junctional epithelium to the alveolar crest.

Once this occurs, junctional epithelium forms from reduced enamel epithelium, one of the products of the enamel organ, and divides rapidly.

FDC-SP is highly expressed in the junctional epithelium and well as in the tonsils, prostate, lymph nodes and trachea.

The electron-lucent zone is adjacent to the cells of the junctional epithelium and might be considered a continuation of the lamina lucida as both are seen to harbour hemidesmosomes.

Damage to the junctional epithelium results in it being irregular in texture, rather than smooth, and the formation of "pocket" epithelium, which is a histopathological characteristic of gum disease.

In the established lesion of periodontal disease, the connective tissue lying subjacent to the junctional epithelium is nearly destroyed, failing to properly support the epithelium and buttress it against the tooth surface.

Cells in the junctional epithelium tend to have wide inter-cellular spaces, to allow the transmission of white blood cells from blood vessels to the bottom of the gingival sulcus, to help prevent disease.

Since the laser energy is quite selective for diseased tissue, the underlying pleuropotential connective tissue is spared, thereby permitting healing and regeneration rather than formation of a pocket seal by long junctional epithelium.

Because it is impossible to perfectly restore a tooth to the precise coronal edge of the junctional epithelium, it is often recommended to remove enough bone to have 3mm between the restorative margin and the crest of alveolar bone.

Based on the 1961 paper by Gargulio, the mean biologic width was determined to be 2.04 mm, of which 1.07 mm is occupied by the connective tissue attachment and another approximate 0.97 mm is occupied by the junctional epithelium.

The junctional epithelium, a non-keratinized stratified squamous epithelium, lies immediately apical to the sulcular epithelium, which lines the gingival sulcus from the base to the free gingival margin, where it interfaces with the epithelium of the oral cavity.
