This pocket is common in dogs and cats. The periodontal tissues
migrate apically and probing will reveal an increase in depth from
the normal anatomical sulcus.
The entire pocket is coronal to the alveolar crestal bone and within
soft tissue. Attachment loss will vary in severity but, in most
cases, the pocket will be bound by necrotic cementum on the root
surface and chronically inflamed gingiva.
