Surfaces that are nearest the cheeks or lips are referred to as either buccal (when found on posterior teeth nearest the cheeks) or labial (when found on anterior teeth nearest the lips). Those nearest the tongue are known as lingual. Lingual surfaces can also be described as palatal when found on maxillary teeth beside the hard palate.
When these processes fail to fuse fully, a cleft lip, cleft palate, or both can result. The nasolabial folds are the deep creases of tissue that extend from the nose to the sides of the mouth. One of the first signs of age on the human face is the increase in prominence of the nasolabial folds.
In 1909, Charles A. Clark described a radiographic procedure for localizing impacted teeth to determining their relative antero-posterior position. [1] If the two teeth (or, by extension, any two objects, such as a tooth and a foreign object) are located in front of one another relative to the x-ray beam, they will appear superimposed on one another on a dental radiograph, but it will be ...
The mouth is the body orifice through which many animals ingest food and vocalize.The body cavity immediately behind the mouth opening, known as the oral cavity (or cavum oris in Latin), [2] is also the first part of the alimentary canal, which leads to the pharynx and the gullet.
The function of this molar is similar to that of all molars in regard to grinding being the principal action during mastication, commonly known as chewing. There are usually four cusps on maxillary molars, two on the buccal (side nearest the cheek) and two palatal (side nearest the palate ).
The formation of secondary palate starts with the growing of tissues vertically and mesially forming the right and left lateral palatal shelves. [46] On the week 8, the tongue will be withdrawn downwards and the right and left lateral palatal shelves will be rapidly elevated, flipped into a horizontal orientation and fuse together from the ...
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.

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]
