labial mucosa

Less often, the labial mucosa, the palate or the floor of mouth may be affected.

In this condition, lesions infrequently involve also the ventral tongue and buccal or labial mucosa.

Although these "high risk" sites are recognized, statistically, leukoplakia is more common on the buccal mucosa, alveolar mucosa, and the lower labial mucosa.

The most common sites affected are the buccal mucosa, the labial mucosa and the alveolar mucosa, although any mucosal surface in the mouth may be involved.

When minor glands are rarely involved, caliculi are more likely in the minor glands of the buccal mucosa and the maxillary labial mucosa.

Sometimes the tongue or the labial mucosa (the inside lining of the lips) is affected by a similarly produced lesion, termed morsicatio linguarum and morsicatio labiorum respectively.

Most usually, the lesions are on the buccal mucosa, but sometimes on the labial mucosa, alveolar ridge, floor of the mouth, ventral surface of the tongue or soft palate.

The most common and simple treatment is construction of a specially made acrylic prosthesis that covers the biting surfaces of the teeth and protects the cheek, tongue and labial mucosa (an occlusal splint).

(ii) The uncommon form is consisted from similar lesions throughout the oral cavity (on the tongue and in addition also on the buccal mucosa, labial mucosa, soft palate or floor of the mouth).

Labial mucosa, buccal mucosa, tongue, floor of mouth, and soft palate are more severely affected by chemotherapy than attached, heavily keratinized tissues such as hard palate and gingiva; this may be due to their faster rate of epithelial cell turnover.

When lesions involve other oral mucosa in addition to the dorsal and lateral tongue, the condition is called migratory stomatitis (or ectopic geographic tongue); in this uncommon condition, lesions infrequently involve also the ventral tongue and buccal or labial mucosa, the soft palate and floor of the mouth.
