The buccal mucosa, along with the gingival and sublingual mucosa, is part of the oral mucosa. [15] It is composed of non-keratinised tissue. Unlike intestinal and nasal mucosae, it lacks tight junctions and is instead equipped with loose intercellular links of desmosomes , gap junctions and hemidesmosomes . [ 7 ]
Sublingual and buccal medication administration is a way of giving someone medicine orally (by mouth). Sublingual administration is when medication is placed under the tongue to be absorbed by the body. The word "sublingual" means "under the tongue." Buccal administration involves placement of the drug between the gums and the cheek.
The mouth consists of two regions: the vestibule and the oral cavity proper. The vestibule is the area between the teeth, lips and cheeks. [3] The oral cavity is bounded at the sides and in front by the alveolar process (containing the teeth) and at the back by the isthmus of the fauces. Its roof is formed by the hard palate.
To check the oral mucosa, the patient's cheek is exposed with a tongue depressor and the tissues inspected with a penlight. Healthy tissue appears moist, smooth, shiny and pink. Stensen's duct is opposite the second molar.
Evaluating the systemic transmucosal drug delivery, the buccal mucosa is the preferred region as compared to the sublingual mucosa. Oral Thin Films (Oral Dissolvable Strips) address several of the disadvantages of tablets or capsules such as dysphagia or the inability to adjust dosing to patient parameters, often resulting to a lack of ...
Around 800 to 1,000 minor salivary glands are located throughout the oral cavity within the submucosa [12] of the oral mucosa in the tissue of the buccal, labial, and lingual mucosa, the soft palate, the lateral parts of the hard palate, and the floor of the mouth or between muscle fibers of the tongue. [13]
Leukoedema lesions disappear when the mucosa is stretched, which helps to differentiate it from other white lesions in the mouth. [2] The differential diagnosis is with leukoplakia , oral candidiasis , oral lichen planus , white sponge nevus , morsicatio buccarum , [ 3 ] hereditary benign intraepithelial dyskeratosis and dyskeratosis congenita.
