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).Dredge turning gland: Dredge Turning Gland is a Trailing Suction Hopper Dredger component.Submandibular gland: The paired submandibular glands are major salivary glands located beneath the floor of the mouth. They each weigh about 15 grams and contribute some 60–67% of unstimulated saliva secretion; on stimulation their contribution decreases in proportion as the parotid secretion rises to 50%.Serous demiluneStreptococcus mutans: Streptococcus mutans is facultatively anaerobic, Gram-positive coccus-shaped bacterium commonly found in the human oral cavity and is a significant contributor to tooth decay.Dental plaque: Dental plaque is a biofilm or mass of bacteria that grows on surfaces within the mouth. It appears as a white or pale yellow "slime layer", that is commonly found between the teeth and along the cervical margins.Dental cariesHistatin: Histatins are proteins found in saliva. They are antimicrobial and antifungal proteins, and have been found to play a role in wound-closure.Actinomyces israelii: Actinomyces israelii is a species of Gram-positive, rod-shaped bacteria within the Actinomyces. Known to live commensally on and within humans, A.
