Why Keratinized Gingiva Is Important?


Keratinized tissue, also known as keratinized mucosa, refers to the band of tissue surrounding your teeth at the point where they meet the gums. The word “keratinized” is used to describe cells that produce large amounts of a protein called keratin, making them strong and better at forming barriers.

What does Keratinized mucosa mean and where can it be found?

Keratinized mucosa is found at the vast majority of implant sites. It includes a highly collagenous connective tissue layer with an orthokeratinized epithelium. … The thickness of keratinized mucosa at the depth of the sulcus was 1 mm greater at implant sites than in natural teeth.

How do you increase Keratinized tissue?

One of the following techniques was utilized to increase the amount of keratinized tissue: apically positioned flap, pedicle graft, connective tissue graft, or free gingival graft.

Is buccal mucosa Keratinized?

For example, the epithelium lining the floor of the mouth, the ventral side of the tongue, the buccal mucosa, and the soft palate is nonkeratinized; however, the epithelium associated with the gingiva and hard palate is usually keratinized.

How do you do connective tissue grafts?

Connective-tissue grafts.

This is the most common method used to treat root exposure. During the procedure, a flap of skin is cut at the roof of your mouth (palate) and tissue from under the flap, called subepithelial connective tissue, is removed and then stitched to the gum tissue surrounding the exposed root.

Where is Keratinized tissue found?

Keratinized cells are specially structured to be waterproof and reduce evaporation from underlying tissues and are therefore an important part of the epidermis or external skin. They are also found in the oral cavity where eating, speaking and breathing could lead to significant loss of water.

What do you mean by Keratinized?

Keratinization is a word pathologists use to describe cells producing large amounts of a protein called keratin. Cells that produce keratin are stronger than other cells which makes them good at forming a barrier between the outside world and in the inside of the body.

Why are some cells Keratinized?

The cells on the surface of stratified squamous keratinized epithelium are very flat. Not only are they flat, but they are no longer alive. They have no nucleus or organelles. They are filled with a protein called keratin, which is what makes our skin waterproof.

Is all gingiva Keratinized?

Attached gingiva – This tissue is adjacent to the free gingiva and is keratinized and firmly attached to the bone structure. It can range from 3-12 mm in height. Free gingiva – This tissue is not attached and forms a collar around the tooth.

How do you know if epithelium is Keratinized?

The surface layer of keratinized epithelium is composed of dead cells which have keratin while the surface layer of nonkeratinized epithelium is composed of living cells and keratin is absent in those cells.

What happens during the process of Keratinization?

Protein involved in keratinization, the process in which the cytoplasm of the outermost cells of the vertebrate epidermis is replaced by keratin. Keratinization occurs in the stratum corneum, feathers, hair, claws, nails, hooves, and horns.

How do you calculate Keratinized gingiva?

Width of keratinized gingiva was measured as the distance from the gingival margin to the mucogingival junction. Sulcus depth was measured as the distance from the gingival margin to base of the sulcus.


What type of tissue is attached gingiva?

The gingiva is composed of fibrous tissue covered by mucous membrane that is firmly attached to the periosteum of the alveolar processes of the mandible and maxilla. The lower gingiva includes the mucosa covering the mandible from the gingival-buccal gutter to the origins of the mobile mucosa on the floor of the mouth.

Is the hard palate Keratinized?

In the adult the epithelium of the hard palate is keratinized.

What is the Keratinized layer?

The epidermis is a keratinized stratified squamous epithelium, which, in thick skin, has a very thick keratinized layer known as the stratum corneum. A few layers of darkly-stained cells constitute the stratum granulosum, beneath which are several cell layers of the stratum spinosum.

How does a cell become Keratinized?

As the replacement cells move closer to the surface of the epidermis, they produce keratin (from the Greek keras, meaning “horn”), a tough protein. … The transformation of cells into keratin breaks down the cells’ nuclei and organelles until they can no longer be distinguished.

What is the clear layer?

The stratum lucidum (Latin for “clear layer”) is a thin, clear layer of dead skin cells in the epidermis named for its translucent appearance under a microscope. It is readily visible by light microscopy only in areas of thick skin, which are found on the palms of the hands and the soles of the feet.

What is function of oral cavity?

The oral cavity represents the first part of the digestive tube. Its primary function is to serve as the entrance of the alimentary tract and to initiate the digestive process by salivation and propulsion of the alimentary bolus into the pharynx.

What type of tissue is simple squamous tissue?

Simple squamous epithelium, also known as simple squamous epithelial tissue or pavement epithelium, is an epithelial tissue that is composed of a single layer of epithelial cells. The term ‘pavement epithelium’ comes from its tile- or brick-like appearance.

What is oral region?

The oral cavity includes the lips, hard palate (the bony front portion of the roof of the mouth), soft palate (the muscular back portion of the roof of the mouth), retromolar trigone (the area behind the wisdom teeth), front two-thirds of the tongue, gingiva (gums), buccal mucosa (the inner lining of the lips and …

How long after gum graft can I eat normally?

When can I eat my regular diet after a gum graft? Typically, your gum graft should heal within 14 days. After that, you can resume eating as you wish.

How long do stitches stay in after gum graft?

Sutures (stitches) will usually have to be removed approximately 10 days to 2 weeks following your surgery. Do not disturb the sutures with your tongue, toothbrush or any other device. Displacement of sutures will impair healing and affect the success of your procedure.

Can gums grow back?

The bottom line. Receding gums are a common condition. Even with good oral hygiene habits, aging and genetics can still cause gum loss. While your gum tissue can’t grow back, there are many treatment options that can help stop or slow down the process.
