The gingival epithelium comprise the epithelial tissue that covers sluts pron external surface of the gingiva as well as the epithelium lining the gingival sulcus and the junctional epithelium Fig. The gingival epithelium is subdivided into 3 sections, the oral epithelium OEthe sulcular epithelium SEand the junctional videos sexpur JE.
The oral oral extends from the mucogingival junction to the gingival margin. It is continuous with the sulcular epithelium that lines oral lateral aspect of the gingival sulcus. The junctional epithelium forms the dentoepithelial junction apical to the sulcus. Its coronal end forms the bottom of the gingival sulcus and is overlapped by the sulcular epithelium.

Oral Mucosal Epithelial Cells
Oral Epithelium B. Microscopic features 1.
Oral epithelium It is the stratified, squamous keratinizing epithelium, that lines cell vestibular and oral surfaces of the gingiva. It extends from the mucogingival junction to the gingival margin see Fig.
The oral epithelium consists of a cell layer stratum basaleSB epithelial, a spinous layer stratum spinosumSSa granular layer stratum epithelialSG and a cornified layer stratum corneumSC. It is designed primarily for protection against mechanical injury during mastication.
Resistance to mechanical injury is mediated primarily by the numerous intercellular junctions, mostly desmosomesthat hold the cells tightly together and the cornified layer. The cornified layer and the relatively narrow intercellular spaces also contribute to the relative lack of permeability.
