Which type of gingival pocket is characterized by no destruction of supporting periodontal tissues?

The type of gingival pocket characterized by no destruction of supporting periodontal tissues is the gingival pocket. This condition occurs when there is an increase in the depth of the gingival sulcus due to inflammation of the gingiva, rather than destruction of the periodontal attachment apparatus.

In a gingival pocket, the attachment of the periodontal fibers is maintained at or above the cementoenamel junction, meaning that although the gingival tissue may be swollen and inflamed, the underlying bone and periodontal ligament are intact. This difference is crucial because it indicates that the condition can potentially be resolved with appropriate periodontal care, focusing on reducing inflammation and improving oral hygiene.

Other types of pockets, such as intrabony pockets and suprabony pockets, involve changes to the supporting structures of the teeth, including the loss of periodontal attachment and destruction of alveolar bone. A deep pocket typically refers to a probing depth that may indicate a significant loss of periodontal support and is not limited to gingival inflammation alone. Thus, it's the gingival pocket's lack of attachment loss that defines it as distinct from these other types of periodontal conditions.
