What type of tissue is inside the mouth?
The oral cavity is lined by a mucous membrane (the oral mucosa) consisting of a stratified squamous epithelium, which may or may not be keratinized, and an underlying connective tissue layer, the lamina propria.
What cell makes up the inside lining of the mouth?
The oral mucosal epithelium is a barrier that separates the underlying tissues from their environment. It consists of two layers, the surface stratified squamous epithelium and the deeper lamina propria.
What is an oral mucosal lesion?
Broadly speaking, oral pathology can present as a mucosal surface lesion (white, red, brown, blistered or verruciform), swelling present at an oral subsite (lips/buccal mucosa, tongue, floor of mouth, palate and jaws; discussed in an accompanying article by these authors)1 or symptoms related to teeth (pain, mobility).
What is oral mucosal disease?
What is oral mucosal disease? The oral mucosa is the mucous membrane lining or “skin” inside of the mouth, including cheeks and lips. People with oral mucosal diseases may develop painful mouth sores or ulcers on this lining. Mucosal diseases can affect any mucous membrane.
How are oral mucosal lesions treated?
Purpose: One of the preferred treatment options for oral mucosal lesions (eg, leukoplakia and lichen planus) is excision, with or without the use of a coverage agent.
Are all white lesions in mouth cancerous?
Although white lesions constitute only 5% of oral pathoses, some of these lesions such as leukoplakia, lichen planus, and proliferative verrucous leukoplakia have malignant potential as high as 0.5–100% [3].
What does mucosal mean?
Listen to pronunciation. (myoo-KOH-suh) The moist, inner lining of some organs and body cavities (such as the nose, mouth, lungs, and stomach). Glands in the mucosa make mucus (a thick, slippery fluid).

Leukoplakia is a condition that involves white patches or spots on the inside of the mouth. It can be caused by chewing tobacco, heavy smoking, and alcohol use.
What does white lesion in mouth look like?
Oral lesions most commonly appear as white epithelial thickening arranged in a network pattern (Wickham striae) with erythema of the surrounding mucosa. White patches, erythematous erosions, and ulcers may also occur. The white lesions are not painful, but the erosions and ulcers are usually painful.
What is the common mucosal immune system?
The mucosal immune system is the first line of defense against microbial and dietary antigens. It connects closely regulated inductive (Peyer’s patches) and effector (lamina propria) tissues for the induction of the immune (IgA) response sites that maintain immunological homeostasis in the gut.
What is a mucosal infection?
Mucosal disorders are diseases of the mucous membranes of the mouth and genitals caused by yeast, viruses and bacteria. Mucosal disorders include: Candidiasis (yeast infection): Candidiasis is an infection caused by excess yeast on the skin or mucus membranes.
