In dentistry, the linea alba (from Latin 'white line') [1] is a horizontal streak on the buccal mucosa (inner surface of the cheek), level with the occlusion (biting plane). ). It usually extends from the commissure to the posterior teeth, and can extend to the inner lip mucosa and corners of the mo
Alveolar mucosa, the lining between the buccal and labial mucosae. It is a brighter red, smooth, and shiny with many blood vessels, and is not connected to underlying tissue by rete pegs. [6] Buccal mucosa, the inside lining of the cheeks; part of the lining mucosa. Labial mucosa, the inside lining of the lips; part of the lining mucosa. [7]
There is a diffuse, gray-white, milky opalescent appearance of the mucosa which usually occurs bilaterally on the buccal mucosa. Less often, the labial mucosa, the palate or the floor of mouth may be affected. The surface of the area is folded, creating a wrinkled, white streaked lesion. [2]
The lesions are located on the mucosa, usually bilaterally in the central part of the anterior buccal mucosa and along the occlusal plane level (the level at which the upper and lower teeth meet). Sometimes, the tongue or the labial mucosa (the inside lining of the lips) is affected by a similarly produced lesion, termed morsicatio linguarum ...
Smokeless tobacco keratosis (STK) [4] is a condition which develops on the oral mucosa (the lining of the mouth) in response to smokeless tobacco use. Generally it appears as a white patch, located at the point where the tobacco is held in the mouth. The condition usually disappears once the tobacco habit is stopped.
Although these "high risk" sites are recognized, statistically, leukoplakia is more common on the buccal mucosa, alveolar mucosa, and the lower labial mucosa. [30] Leukoplakia of the floor of the mouth and tongue accounts for over 90% of leukoplakias showing dysplasia or carcinoma on biopsy. [ 2 ]
“What was on the surface of my tongue was the tip of the iceberg, and I actually had a four-centimeter mass that was inside the tongue into the floor of my mouth,” Smith, 48, of Fairfield ...
They are characterized as clustered, white lesions on the buccal mucosa (opposite the upper 1st & 2nd molars) and are pathognomonic for measles. [2] The textbook description of Koplik spots is ulcerated mucosal lesions marked by necrosis, neutrophilic exudate, and neovascularization. [3]
