![Gingival and periodontal pockets are extensions of the gingival sulcus, which exists in health. Other letters: A, crown of the tooth, covered by enamel. B, root of the tooth, covered by cementum. C, alveolar bone. D, subepithelial connective tissue. E, oral epithelium. H, principal gingival fibers. I, alveolar crest fibers of the PDL. J, horizontal fibers of the PDL. K, oblique fibers of the PDL.](/Images/godic/202501/15/Gingival_sulcus0906.PNG")
![1: Total loss of attachment (clinical attachment loss, CAL) is the sum of 2: Gingival recession, and 3: Probing depth](/Images/godic/202501/15/Periodontal_terms_diagram_gingival_recession0906.png")
Both the gingival and periodontal pocket are extensions of the gingival sulcus, which exists in health. Gingival and periodontal pockets are dental terms indicating the presence of an abnormal depth of the gingival sulcus near the point at which the gingival tissue contacts the tooth.
