In dental anatomy, the gingival sulcus is an area of potential space between a tooth and the surrounding gingival tissue and is lined by sulcular epithelium. The depth of the sulcus (Latin for groove) is bounded by two entities: apically by the gingival fibers of the connective tissue attachment and coronally by the free gingival margin.
The interdental gum lies between the teeth. They occupy the gingival embrasure, which is the interproximal space beneath the area of tooth contact. The interdental papilla can be pyramidal or have a "col" shape. Attached gums are resistant to the forces of chewing and covered in keratin.
The oral cavity has sometimes been described as a mirror that reflects the health of the individual. [2] Changes indicative of disease are seen as alterations in the oral mucosa lining the mouth, which can reveal systemic conditions, such as diabetes or vitamin deficiency , or the local effects of chronic tobacco or alcohol use.

A periodontal pocket can become an infected space and may result in an abscess formation with a papule on the gingival surface. Incision and drainage of the abscess may be necessary, as well as systemic antibiotics; placement of local antimicrobial delivery systems within the periodontal pocket to reduce localized infections may also be considered.
In dental anatomy, the free gingival margin is the interface between the sulcular epithelium and the epithelium of the oral cavity.This interface exists at the most coronal point of the gingiva, otherwise known as the crest of the marginal gingiva.
In dental anatomy, the junctional epithelium (JE) is that epithelium which lies at, and in health also defines, the base of the gingival sulcus (i.e. where the gums attach to a tooth). The probing depth of the gingival sulcus is measured by a calibrated periodontal probe .
The interdental papilla, also known as the interdental gingiva, is the part of the gums (gingiva) that exists coronal to the free gingival margin on the mesial and distal surfaces of the teeth. The interdental papillae fill in the area between the teeth apical to their contact areas to prevent food impaction; they assume a conical shape for the ...
The PDL is a part of the periodontium that provides for the attachment of the teeth to the surrounding alveolar bone by way of the cementum. The PDL appears as the periodontal space of 0.4 to 1.5 mm [citation needed] on radiographs, a radiolucent area between the radiopaque lamina dura of the alveolar bone proper and the radiopaque cementum.
