The oral epithelium is a keratinized stratified squamous epithelium that extends from the mucogingival junction to the free gingival margin. In some areas of the most superficial layer, the stratum corneum, the cells maintain their nuclei and are considered parakeratinized. If no nuclei are present in the stratum corneum, this epithelium is considered orthokeratinized. In addition to the keratinocytes, other cells can be found in the oral epithelium, such as melanocytes, which give pigmentation to the epithelium; Langerhans cells, which play a role in the immune response; and Merkel cells, which are important for sensory function.
