Gastric mucosal barrier: The gastric mucosal barrier is the property of the stomach that allows it to contain acid.Dark FieldsSustentacular cellListerineMouthguard: A mouthguard is a protective device for the mouth that covers the teeth and gums to prevent and reduce injury to the teeth, arches, lips and gums. A mouthguard is most often used to prevent injury in contact sports, as a treatment for bruxism or TMD, or as part of certain dental procedures, such as tooth bleaching.GastritisAcute esophageal necrosisSteel tongue drum: A steel tongue drum, tank drum or hank drum is a round steel slit/tongue drum originally fashioned from a propane tank.Stomach diseaseGastric erosion: Gastric erosion occurs when the mucous membrane lining the stomach becomes inflamed. Some drugs, as tablets, can irritate this mucous membrane, especially drugs taken for arthritis and muscular disorders, steroids, and aspirin.Saliva testing: Saliva testing is a diagnostic technique that involves laboratory analysis of saliva to identify markers of endocrine, immunologic, inflammatory, infectious, and other types of conditions. Saliva is a useful biological fluid for assaying steroid hormones such as cortisol, genetic material like RNA, proteins such as enzymes and antibodies, and a variety of other substances, including natural metabolites, including saliva nitrite, a biomarker for nitric oxide status (see below for Cardiovascular Disease, Nitric Oxide: a salivary biomarker for cardio-protection).TrismusCheek reconstruction: Cheek reconstruction the cheek constitutes the facial periphery and plays a key role in the maintenance of oral competence and mastication, the facial manifestation of human emotion, and the support of neighboring primary structures. The repair of cheek defects seeks to achieve both aesthetic and functional ends that must be carefully considered by the reconstructive surgeon.Intestinal metaplasia: 200px|right|thumb|Intestinal metaplasia (top middle of image) of the gastric antrum and [[stomach cancer|adenocarcinoma of the stomach (left/centre of image). H&E stain.CagA: Helicobacter pylori virulence factor CagA (cytotoxin-associated gene A) is a 120–145kDa protein encoded on the 40kb cag pathogenicity island (PAI). H.Brain biopsyHalitosisGastrin: Gastrin is a peptide hormone that stimulates secretion of gastric acid (HCl) by the parietal cells of the stomach and aids in gastric motility. It is released by G cells in the pyloric antrum of the stomach, duodenum, and the pancreas.Congenital lip pit: Congenital lip pits (also known as "Congenital sinus of the lower lip," "Lip sinus," and "Midline sinus of the upper lip") is a congenital disorder characterized by the presence of pits and possibly associated fistulas in the lips. They are often hereditary, and may occur alone or in association with cleft lip and palate, termed Van der Woude syndrome.Stratified squamous epithelium: A stratified squamous epithelium consists of squamous (flattened) epithelial cells arranged in layers upon a basal membrane. Only one layer is in contact with the basement membrane; the other layers adhere to one another to maintain structural integrity.Red Noses: Red Noses is a comedy about the black death by Peter Barnes, first staged at Barbican Theatre in 1985. It depicted a sprightly priest, originally played by Antony Sher, who travelled around the plague-affected villages of 14th century France with a band of fools, known as God's Zanies, offering holy assistance.Epithelial dysplasia: Epithelial dysplasia, a term becoming increasingly referred to as intraepithelial neoplasia, is the sum of various disturbances of epithelial proliferation and differentiation as seen microscopically. Individual cellular features of dysplasia are called epithelial atypia.
