The oral cavity serves as the starting point of the digestive track and facilitates breathing as a channel for airflow to the lungs. The borders of the oral cavity include the lips in the front, cheeks on the side, mylohyoid muscle/associated soft tissue below, soft and hard palate above, and the oropharynx at the back. The most important ...
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.
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. In tetrapod vertebrates , the mouth is bounded on the outside by the lips and cheeks — thus the oral cavity is also known as the buccal cavity ...

Oral microbiology is the study of the microorganisms (microbiota) of the oral cavity and their interactions between oral microorganisms or with the host. [1] The environment present in the human mouth is suited to the growth of characteristic microorganisms found there. It provides a source of water and nutrients, as well as a moderate ...
A 1930s poster from the Work Projects Administration promoting oral hygiene. Tooth decay is the most common global disease. [14] Over 80% of cavities occur inside fissures in teeth where brushing cannot reach food left trapped after eating and saliva and fluoride have no access to neutralize acid and remineralize demineralized teeth, unlike easy-to-clean parts of the tooth, where fewer ...
Teeth, saliva, and oral tissues are the major components of the oral environment in which the oral microbiome resides. Like most environments, some oral environments, such as teeth and saliva, are abiotic (non-living), and some are living, such as the host immune system or host mouth mucosal tissues- including gums, cheek ("buccal") and tongue (when present).
Oral cancer, also known as oral cavity cancer, tongue cancer or mouth cancer, is a cancer of the lining of the lips, mouth, or upper throat. [6] In the mouth, it most commonly starts as a painless red or white patch , that thickens, gets ulcerated and continues to grow.
