coelomic epithelium
the junctional epithelium, a nonkeratinized stratified squamous epithelium, lies immediately apical to the sulcular epithelium, which lines the gingival sulcus from the base to the free gingival margin, where it interfaces with the epithelium of the oral cavity. the gingival sulcus is bounded by the enamel of the crown of the tooth and the sulcular epithelium. immediately apical to the base of the pocket, and coronal to the most coronal of the gingival fibers is the junctional epithelium. the je attaches to the surface of the tooth by way of the ea with hemidesmosomes and is, on average, roughly 1 mm in width in the apico-coronal dimension, constituting about one half of the biologic width. the attachment of the je to the tooth surface can occur on enamel, cementum, or dentin. the position of the ea on the tooth surface is initially on the cervical half of the anatomical crown when the tooth first becomes functional after tooth eruption.
junctional epithelium
it is in the established lesion that epithelial proliferation and apical migration begin. in health, the junctional epithelium creates the most coronal attachment of the gum tissue to the tooth at or near the cementoenamel junction. in the established lesion of periodontal disease, the connective tissue lying subjacent to the junctional epithelium is nearly destroyed, failing to properly support the epithelium and buttress it against the tooth surface. in response to this, the junctional epithelium proliferates and grows into the vacant underlying spaces, effectively causing the level of its attachment to migrate towards apically, revealing more tooth structure than is normally evident "supragingivally" (above the level of the gumline) in health.
