Gingival retraction or gingival recession is when there is lateral movement of the gingival margin away from the tooth surface. [1] [2] It is usually termed gingival retraction as an intentional procedure, and in such cases it is performed by mechanical, chemical, or electrical means in order to perform certain dental surgery procedures.
In human anatomy, the mouth is the first portion of the alimentary canal that receives food and produces saliva. [2] The oral mucosa is the mucous membrane epithelium lining the inside of the mouth. In addition to its primary role as the beginning of the digestive system, the mouth also plays a significant role in communication.
Gingival recession is when there is an apical movement of the gum margin away from the biting (occlusal) surface. [4] It may indicate an underlying inflammation such as periodontitis [ 5 ] or pyorrhea , [ 5 ] a pocket formation, dry mouth [ 5 ] or displacement of the marginal gums away from the tooth by mechanical (such as brushing), [ 5 ...
The fimbriated fold of tongue, also plica fimbriata, is a slight fold of the mucous membrane on the underside of the tongue which runs laterally on either side of the frenulum.
Healthy gingiva can be described as stippled, pale or coral pink in Caucasian people, with various degrees of pigmentation in other races. The gingival margin is located at the cemento-enamel junction without the presence of pathology. The gingival pocket between the tooth and the gingival should be no deeper than 1–3mm to be considered ...
The interdental papilla, also known as the interdental gingiva, is the part of the gums (gingiva) that exists coronal to the free gingival margin on the mesial and distal surfaces of the teeth. The interdental papillae fill in the area between the teeth apical to their contact areas to prevent food impaction; they assume a conical shape for the ...
The human digestive system consists of the gastrointestinal tract plus the accessory organs of digestion (the tongue, salivary glands, pancreas, liver, and gallbladder). Digestion involves the breakdown of food into smaller and smaller components, until they can be absorbed and assimilated into the body.
The gastrointestinal tract (GI tract, digestive tract, alimentary canal) is the tract or passageway of the digestive system that leads from the mouth to the anus. The GI tract contains all the major organs of the digestive system, in humans and other animals, including the esophagus , stomach , and intestines .
