There are multiple definitions:

1. junctional epithelium(English)

   • adjacent to the tooth is that part of the gingiva which attaches the connective tissue to the tooth surface. It forms a band 2 to 3 mm wide around the tooth, and is approximately 15 to 30 cells thick coronally and tapers to a single cell apically. This attachment is continuously being renewed throughout life with high turnover rate (4 to 6 days) compared with oral epithelium (6 to12 days). Has a key role in the maintenance of periodontal health by creating the firm attachment of the soft gingival tissue to hard tooth tissue. However, as it is permeable, it serves as a pathway for diffusion of the metabolic products of plaque bacteria such as toxins, chemotactic agents and antigens. Even when the gingiva do not appear inflamed clinically, the JE has many polymorphonuclear leucocytes moving through it towards the sulcus. These form an important part of the defense mechanism
