sulcular epithelium

The sulcular epithelium is that epithelium which lines the gingival sulcus.

The sulcular epithelium is nonkeratinized.

The free gingival margin is the interface between the sulcular epithelium and the epithelium of the oral cavity.

There are three different types of epithelium associated with the gingiva: gingival, junctional, and sulcular epithelium.

The sulcular epithelium is nonkeratinized stratified squamous tissue on the gingiva which touches but is not attached to the tooth.

The gingival sulcus is an area of potential space between a tooth and the surrounding gingival tissue and is lined by sulcular epithelium.

Bleeding on probing, often abbreviated BOP, is a sign of inflammation and indicates some sort of destruction and erosion to the lining of the sulcus or the ulceration of sulcular epithelium.

The junctional epithelium, a non-keratinized 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.
