Question: 1 / 400

What type of pocket is generated by an apical migration of the junctional epithelium?

Periodontal

The type of pocket generated by an apical migration of the junctional epithelium is classified as a periodontal pocket. This occurs when there is loss of connective tissue attachment and bone loss in the periodontal structures, allowing the junctional epithelium to move lower down onto the tooth root. The apical migration is a hallmark of periodontal disease, specifically more advanced stages like periodontitis, where the supporting structures of the teeth are compromised.

With periodontal pockets, there is an increase in the depth of the sulcus, which can be assessed through clinical measurements. This pathologic process often results in the formation of pockets that can harbor bacteria, contributing to further tissue destruction if not managed properly. Understanding the distinction between different types of pockets is essential for accurate diagnosis and treatment planning in periodontal therapy.
