Gingival sulcus

Gingival sulcus. 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. F, free gingival margin. H, principle gingival fibers. I, alveolar crest fibers of the PDL. J, horizontal fibers of the PDL. K, oblique fibers of the PDL.

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 attachement and coronally by the free gingival margin.
