a bag or pouch; see also cavity, recess, and sac.
infrabony pocket (intra-alveolar pocket) (intrabony pocket) a periodontal pocket in which the bottom is apical to the level of the adjacent alveolar bone.
periodontal pocket a gingival sulcus that extends abnormally deep into the periodontal ligament apically to the original level of the resorbed alveolar crest.
suprabony pocket (supracrestal pocket) a periodontal pocket in which the bottom is coronal to the underlying bone.

pock·et

(pok'ĕt),
1. A cul-de-sac or pouchlike cavity.
2. A diseased gingival attachment; a space between the inflamed gum and the surface of a tooth, limited apically by an epithelial attachment.
3. To enclose within a confined space, as the stump of the pedicle of an ovarian or other abdominal tumor between the lips of the external wound.
4. A collection of pus in a nearly closed sac.
5. To approach the surface at a localized spot, as with the thinned-out wall of an abscess that is about to rupture.

/pock·et/ (pok´et) a bag or pouch.
endocardial pockets  sclerotic thickenings of the mural endocardium, occurring most often on the left ventricular septum below an insufficient aortic valve.
gingival pocket  a gingival sulcus deepened by pathological conditions, caused by gingival enlargement without destruction of the periodontal tissue.
pacemaker pocket  the subcutaneous area in which the pulse generator and pacing leads of an internal pacemaker are implanted, usually developed in the prepectoralis fascia or the retromammary area.
periodontal pocket  a gingival sulcus deepened into the periodontal ligament apically to the original level of the resorbed alveolar crest.

pocket

[pok′ət]
a saclike space. See also cavity, pouch, recess.

pocket

A pathologically altered or enlarged gingival sulcus, so defined when the distance from the gingival margin is ≥ 3 mm. In a healthy periodontium, the gingiva is snug around the teeth, and the gingival crevice near zero; with inflammation, increased bulk of gingival tissue around the teeth results in increased depth of tissue around the teeth which, if confined to the gingiva, is termed gingival pseudopocket; if it extends into the periodontium, it is termed periodontal pocket.

pocket,

n in dentistry, a deepened gingival sulcus. See also gingival sulcus.
pocket, bleeding,
n an occurrence that denotes ulcerations of the pocket epithelium, with hemorrhaging through the broken surface from exposed connective tissue capillaries. May happen as a result of probing, oral hygiene, or other manipulation of the tissues such as dental procedures or eating.
pocket bottom,
n the base of the pocket, marked or limited by the epithelial attachment to the cementum of the root (periodontal pocket) or the enamel of the crown (gingival pocket). The depth from the base of the pocket to the gingival crest is measured by the periodontal probe.
pocket, calculus,
n the calcified deposits that usually occupy the pocket. It is attached to the tooth structure, with the gingival tissues tightly adapted to the surface of the calculus.
pocket, deepening,
n an increase of the depth of the pocket, which depends on apical proliferation of the epithelial attachment alongside the cementum, with subsequent separation from the tooth, or on hyperplasia of the gingivae resulting from inflammation.
pocket, depth of,
n the measurement, usually expressed in millimeters, of the distance between the gingival crest and the base of the pocket using a periodontal probe.
pocket, elimination,
n the application of therapeutic measures to obtain a healthy gingival attachment and an intact, functioning epithelial attachment. The procedures employed include curettage (root and gingival), reattachment, or new attachment operations, gingivectomy and gingivoplasty, and osseous and mucogingival surgical procedures.
pocket, gingival,
n a pseudopocket or false pocket formation; gingival inflammation with edema, hyperplasia, and ulceration of the sulcular epithelium but without apical proliferation of the epithelial attachment.
pocket in marginal periodontitis,
n a condition in which the inflammatory process has progressed from the gingival tissues to the underlying alveolar process. The changes are those associated with gingivitis and, in addition, resorptive bone lesions. The base of the pocket is at the junction of the epithelial attachment to the cementum of the root.
pocket, infrabony,
n a periodontal pocket, the base of which is apical to the crest of the alveolar bone. Consists basically of a vertical resorptive defect in alveolar and supporting bone, overlying which are a band of transseptal fibers connecting adjacent teeth, disintegrated fibers of gingival tissue, inflammatory cellular infiltrate, and hyperplastic pocket epithelium, accompanied by apical migration of the epithelial attachment. Clinical signs are those of periodontitis, associated with radiographic evidence of vertical bone resorption. It has been classified according to the number of remaining osseous walls supporting it for the purpose of therapeutic rationale. Also called
infracrestal pocket, intraalveolar pocket, and
intrabony pocket.
pocket, infracrestal,
n See pocket, infrabony.
pocket, intraalveolar,
n See pocket, infrabony.
pocket, intrabony,
n See pocket, infrabony.
pocket ionization chamber,
pocket, marking,
n the accurate determination and delineation of pocket depth and topography as an aid to diagnosis and prognosis or to provide a guide for the gingivectomy incision or other surgical procedures.
pocket, periodontal,
n a pathologically deepened sulcus, with an ulcerated junctional epithelium and apical proliferation of the epithelial attachment. There is also a loss of bone and disorganization of the periodontal ligament.
pocket, suprabony,
n an area of crestal alveolar bone loss that results in a deepened gingival sulcus.
pocket surgery,
n a generic term referring to gingivectomy and gingivoplasty. See also gingivectomy and gingivoplasty.

pocket

small enough to fit into a pocket, figuratively speaking.

pocket gopher
see gopher.
pocket pet
a general term, used to describe very small animals kept as pets; usually includes hamsters, guinea pigs, gerbils, rats and mice.

Rathke's pouch, cleft, pocket

a diverticulum from the embryonic buccal cavity from which the anterior pituitary is developed.

Rathke's pouch pouch cyst
failure of the ectoderm of Rathke's pouch to differentiate into adenohypophyseal tissue. A cyst fills the space normally occupied by the pituitary gland and the animal is a dwarf with panhypopituitarism.
