*Aphthous stomatitis* (also termed *canker sores*, *recurrent aphthous
stomatitis*, *RAS*, *recurring oral aphthae* and *recurrent aphthous
ulceration*) is a common cause of benign and non-contagious mouth ulcers
(canker sores). This condition is characterized by the repeated formation
of ulcers on the mucous membrane of the oral cavity (the lining of the
mouth), in otherwise healthy individuals.^[1] These ulcers occur
periodically and heal completely between attacks. Symptoms range from a
minor nuisance to interfering with eating and drinking. The cause is not
completely understood, but may involve a T cell mediated immune response
which is triggered by a variety of factors. Different people may have
different triggers, including nutritional deficiencies, local trauma,
stress, hormonal influences, allergies, and a genetic predisposition. The
condition is very common, affecting about 20% of the general population.
There is no cure, and treatments are aimed at reducing pain and speeding
the healing process. Often, the onset of the condition is during childhood
or adolescence and usually lasts for several years before gradually
disappearing, with or without any form of treatment.
