Non-keratinized squamous epithelium covers the soft palate, lips, cheeks and the floor of the mouth. Keratinized squamous epithelium is present in the gingiva and hard palate . [ 3 ] Keratinization is the differentiation of keratinocytes in the granular layer into dead surface cells to form the stratum corneum.
In health, the soft tissue immediately around the teeth is keratinized and is referred to as keratinized tissue or gingiva. Alveolar mucosa is non keratinized oral epithelium and is located apical to the keratinized tissue, delineated by the mucogingival junction (MGJ). It should also be pointed out that mucosa can surround a tooth in health. [4]
Keratinized squamous epithelium is present in the gingiva and hard palate as well as areas of the dorsal surface of the tongue. [ 8 ] [ 9 ] Keratinization is the differentiation of keratinocytes in the stratum granulosum into nonvital surface cells or squames to form the stratum corneum.
Using the mucogingival junction as the boundary demarcating the apical border of the attached gingiva, a periodontal probe is inserted into the gingival sulcus to measure how much of the keratinized gingiva coronal to the mucogingival junction is in fact attached to the underlying bone. The depth of the gingival sulcus, determined by the depth ...
When it comes to maintaining your health, you may be overlooking one of the most important parts of your body: your mouth. Gum disease is the most common oral disease, with studies estimating that ...
Thus, the JE does not mature like keratinized tissue, such as the marginal gingiva or attached gingiva, which fills its matured superficial cells with keratin. Nor does JE mature on a lesser level like nonkeratinized tissue of the sulcular gingiva and throughout the rest of the oral cavity, which enlarges its cells as they mature and migrate ...
The gingival fibers, (H), extend from the cementum (B) into the attached gingiva. Some fibers extend coronally into the crest of the free gingiva, some horizontally, and still other extend horizontally over the crest of the alveolar bone, (C), and then apically to connect on the facial aspect of the buccal plate of the alveolar bone.
Others, including Broome and Taggert [4] and Donn [5] also described the use of SECT grafts for increasing the zone of keratinized tissue. Of the various ways of preparing the graft recipient site, Edel described using two vertical incisions, mesial and distal to the teeth at which the zone of keratinized tissue was intended to be widened.
