The superfi Junctional epithelium is defined as the part of the gingiva that attaches the connective tissue to the tooth surface, forming a band 2–3 mm wide and approximately 15–30 cells thick. It forms a seal around the tooth and provides bacterial barricade by secreting different antimicrobial peptides. It initially forms with the emergence of the tooth into the oral cavity, with the Abstract The junctional epithelium (JE) is an epithelial component that attaches directly to the tooth surface and performs the unique function of protecting against bacterial infections; its Learn about the significance of cell adhesion in tissue organization and pathology, as well as the role of adhesion molecules like cadherins, Junctional epithelium, is that epithelium which lies at the base of gingival sulcus.
