What type of epithelial structure characterizes the inner lining of the gingival sulcus?
Explanation
The epithelium lining the inner surface of the gingival sulcus is unique in that it does not have rete pegs. This feature distinguishes it from other gingival epithelia, which often show prominent rete pegs. Additionally, the sulcular epithelium is typically non-keratinized or minimally keratinized, further differentiating it from the keratinized or parakeratinized gingival epithelium.
