Another very common cause of white patches in the mouth is frictional or irritational trauma leading to keratosis. Examples include nicotine stomatitis, which is keratosis in response to heat from tobacco smoking (rather than a response to the carcinogens in tobacco smoke). The risk of malignant transformation is similar to normal mucosa.
Oral candidiasis (Acute pseudomembranous candidiasis), which is also known as oral thrush, among other names, [1] is candidiasis that occurs in the mouth. That is, oral candidiasis is a mycosis (yeast/fungal infection) of Candida species on the mucous membranes of the mouth.
Hairy leukoplakia is a white patch on the side of the tongue with a corrugated or hairy appearance. It is caused by Epstein-Barr virus (EBV) and occurs usually in persons who are immunocompromised, especially those with human immunodeficiency virus infection/acquired immunodeficiency syndrome (HIV/AIDS).
A type of bacteria that causes dental plaque may be behind a treatment-resistant form of colorectal cancer, a study published Wednesday in the journal Nature found.. The particular bacterium ...
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.
Gingivitis is a non-destructive disease that causes inflammation of the gums; [1] ulitis is an alternative term. [2] The most common form of gingivitis, and the most common form of periodontal disease overall, is in response to bacterial biofilms (also called plaque) that are attached to tooth surfaces, termed plaque-induced gingivitis.
Over time, this plaque may be colonized by Candida species. The local environment under a denture is more acidic and less exposed to the cleansing action of saliva, which favors high Candida enzymatic activity and may cause inflammation in the mucosa. C. albicans is the most commonly isolated organism, but occasionally bacteria are implicated. [4]
