bounded by the junctional epithelium
Junctional epithelium
The junctional epithelium is that epithelium which lies at, and in health also defines, the base of the gingival sulcus. It attaches to the surface of the tooth with hemidesmosomes and is, on average, roughly 1 mm in width, constituting about one half of the biologic width.The junctional...
and meets the epithelium of the oral cavity at the height of the free gingival margin
Free gingival margin
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....
