Portions of clinically healthy epithelium from the hard and soft palates, free and attached gingivae, cheek, floor of mouth and lip from the vervet monkey (Cercopithecus aethiops) were examined with the light and with the scanning electron microscope. The epithelia can be subdivided histolocally into keratinized and non‐keratinized types. Each of these has a definite surface appearance irrespective of the region from which they are derived. Non‐keratinized epithelia show a corrugated surface formed by microplications while keratinized epithelia have a cratered or pitted appearance. In addition, the parakeratinized free gingival surface may be masked by the presence of pellicle. The reason for the different surface appearances is obscure but may be related to different intercellular interdigitations in the two types of epithelia.
