junc·tion·al ep·i·the·li·um

a wedge-shaped collar of epithelial cells attached to the tooth surface and to the gingival connective tissue; its coronal aspect forms the base of the gingival crevice.

(jŭngk'shŭn-ăl ep'i-thē'lē-ŭm)
Surface located at the base of the gingival sulcus. It is a cufflike nonkeratinized band of squamous epithelium encircling and affixing itself to the dental surface.

Since the toxic effects of pollutants are often correlated with their concentration in individual tissues and organs, the purpose of the present investigation was to study the effects of cadmium on the maxillary molar junctional epithelium during lactation.
The following karyometric parameters of the different layers of the gingival and junctional epithelium were estimated according described by Sala et al.
(11) It is conceivable that as the tooth continues to erupt, the distance between the CEJ and the junctional epithelium (JE) would increase, without implying that the JE has migrated apically.
The structure of the dental gingival area in rats is quite similar to that observed in humans, (12) with a shallow gingival sulcus and attachment of the junctional epithelium to the tooth surface.
Within neutrophils, human [alpha]-defensins are abundant and work together with the oral epithelium to provide a barrier to microbial colonization, particularly in the junctional epithelium of the tooth surface.
(9) The superficial physiologic dimension represents the free and attached gingival surrounding the tooth, while the crevicular physiologic dimension represents the gingival dimension from the gingival margin to the junctional epithelium. The subcrevicular physiologic space is analogous to the biologic width described (Gargiulo et al.
Periodontitis is accompanied by periodontal pocket formation which is a result of apical migration of junctional epithelium along with significant changes in the levels and density of alveolar bone.
