How many basal laminas are present in the junctional epithelium?

In the junctional epithelium, there are two basal laminas present. This unique structure is significant due to its role in the attachment of the junctional epithelium to both the tooth surface and the underlying connective tissue.

The first basal lamina is associated with the dental enamel, providing a protective barrier and anchoring the epithelium to the tooth. The second basal lamina is located beneath the junctional epithelium, which interfaces with the underlying connective tissue. The presence of these two laminas is essential for the proper function of the junctional epithelium, facilitating its role in maintaining periodontal health and its interaction with the periodontal ligament and alveolar bone.

Understanding the structure of the junctional epithelium, including the dual basal laminas, is crucial for comprehending its function in periodontal disease prevention and the healing process following periodontal treatments. This knowledge aids in recognizing the importance of the junctional epithelium in maintaining a healthy oral environment.
