(a)
What makes up the dentogingival junction?
Sulcular epithelium
Stratum Basal
Junctional epithelium
All of the above
1. The internal basal cell layer of JE is the tissue that attaches to the tooth surface. It is cellular, but it attaches to a non-cellular tooth surface.
2. External cell layer of the JE attaches to lamina propria.

True
False
Cellular to cellular connection
hemidesmosome
desmosome
The (JE) has the highest turnover time in the oral cavity, which takes:
3-6 days
4-6 days
2-5 days
4-7 days
Crevicular epithelium (CE) or sulcular epithelium stands away from the tooth, creating a gingival sulcus, or space, that is filled with:
Gingival Crevicular Fluid (GCF)
Gingival Fluid (GF)
The attached gingiva has an overlying thick layer of:
parakeratinized stratified squamous epithelium
orthokeratinized stratified squamous epithelium
The marginal gingiva has an overlying surface layer of only:
parakeratinized stratified squamous epithelium
orthokeratinized stratified squamous epithelium
At the gingival margin of each tooth is the (a) or free gingiva, which is continuous with the attached gingiva.
The (a) or gingival margin is at the most superficial part of the marginal gingiva.
The (a) separates the attached gingiva from the marginal gingiva on the superficial surface of the gingival tissue
Together the sulcular epithelium and junctional epithelium form the
(a)
The (a) or crevicular epithelium stands away from the tooth, creating a gingival sulcus, or space that is filled with GCF from the adjacent blood supply in the lamina propria.
A deeper extension of the sulcular epithelium is the (a) , which lines the floor of the gingival sulcus and is attached to the tooth surface.
The deepest layer of the (a) , its basal layer, undergoes constant and rapid cell division or mitosis, which allows constant coronal migration as the cells die and are shed into the gingival sulcus.
The JE is attached to the tooth surface by way of ___________ which attaches this tissue to the tooth surface of either enamel, cementum, or dentin.
Epithelial attachment
Dermis attachment
Keratin attachment
Non-keratin attachment
The deeper interface between the thin JE and the underlying _____________ is relatively smooth, without rete ridges or connective tissue papillae; the epithelial cells are loosely packed, with fewer intercellular junctions using desmosomes between cells and more intercellular spaces.
