Aphthous stomatitis, [2] or recurrent aphthous stomatitis (RAS), commonly referred to as a canker sore or salt blister, is a common condition characterized by the repeated formation of benign and non-contagious mouth ulcers (aphthae) in otherwise healthy individuals.
The two most common causes of oral ulceration are local trauma (e.g. rubbing from a sharp edge on a broken filling or braces, biting one's lip, etc.) and aphthous stomatitis ("canker sores"), a condition characterized by the recurrent formation of oral ulcers for largely unknown reasons. Mouth ulcers often cause pain and discomfort and may ...
Causes. Anything that irritates the mucosa in the mouth can cause stomatitis. This includes: Viruses. Gum disease. Irritation from dentures or braces. Biting your cheek. Burning your mouth with ...
Aphthous stomatitis (canker sores) is the recurrent appearance of mouth ulcers in otherwise healthy individuals. The cause is not completely understood, but it is thought that the condition represents a T cell mediated immune response which is triggered by a variety of factors. The individual ulcers (aphthae) recur periodically and heal ...
Both HSV-1, and HSV-2 can be the cause of herpetic gingivostomatitis, [5] although HSV-1 is the source of infection in around 90% of cases. [6] Herpetic gingivostomatitis infections can present as acute or recurrent. Acute infection refers to the first invasion of the virus, and recurrent is when reactivation of the latent virus occurs.

The mouth may act as a reservoir of Candida that reinfects the sores at the corners of the mouth and prevents the sores from healing. [citation needed] A lesion caused by recurrence of a latent herpes simplex infection can occur in the corner of the mouth. This is herpes labialis (a cold sore), and is sometimes termed "angular herpes simplex". [2]
Periodic fever, aphthous stomatitis, pharyngitis and adenitis syndrome is a medical condition, typically occurring in young children, in which high fever occurs periodically at intervals of about 3–5 weeks, frequently accompanied by aphthous-like ulcers, pharyngitis and cervical adenitis (cervical lymphadenopathy). The syndrome was described ...
Sores or ulcerations can become infected by virus, bacteria or fungus.Pain and loss of taste perception makes it more difficult to eat, which leads to weight loss. Ulcers may act as a site for local infection and a portal of entry for oral flora that, in some instances, may cause septicaemia (especially in immunosuppressed patients).
