Oral rinse involves rinsing the mouth with phosphate-buffered saline for 1 minute and then spitting the solution into a vessel that examined in a pathology laboratory. Oral rinse technique can distinguish between commensal candidal carriage and candidiasis. If candidal leukoplakia is suspected, a biopsy may be indicated. [31]
Candidiasis is a fungal infection due to any species of the genus Candida (a yeast). [4] When it affects the mouth, in some countries it is commonly called thrush. [3] Signs and symptoms include white patches on the tongue or other areas of the mouth and throat. [3]
More than 800 species of bacteria colonize oral mucus, 1,300 species are found in the gingival crevice, and nearly 1,000 species comprise dental plaque. The mouth is a rich environment for hundreds of species of bacteria since saliva is mostly water and plenty of nutrients pass through the mouth each day.
Hypersalivation can contribute to drooling if there is an inability to keep the mouth closed or difficulty in swallowing (dysphagia) the excess saliva, which can lead to excessive spitting. Hypersalivation also often precedes emesis (vomiting), where it accompanies nausea (a feeling of needing to vomit).
Frictional keratosis: This typically presents as white plaques on the oral mucosa due to mechanical trauma. When the cause of frictional keratosis is removed the white patch may resolve. Hyperplastic reactive lesions or nodular swellings: These occur in the oral mucosa due to low grade inflammation or trauma. They develop where the mucosa is ...
Saliva on a baby's lips. Saliva (commonly referred to as spit or drool) is an extracellular fluid produced and secreted by salivary glands in the mouth.In humans, saliva is around 99% water, plus electrolytes, mucus, white blood cells, epithelial cells (from which DNA can be extracted), enzymes (such as lingual lipase and amylase), and antimicrobial agents (such as secretory IgA, and lysozymes).
Xerostomia is the subjective sensation of dry mouth, which is often (but not always) associated with hypofunction of the salivary glands. [3] The term is derived from the Greek words ξηρός (xeros) meaning "dry" and στόμα (stoma) meaning "mouth". [4] [5] A drug or substance that increases the rate of salivary flow is termed a sialogogue.
Denture-related stomatitis is a common condition where mild inflammation and redness of the oral mucous membrane occurs beneath a denture.In about 90% of cases, Candida species are involved, [4] which are normally a harmless component of the oral microbiota in many people.
