Stomatitis refers to inflammation of the mucous membrane of the mouth, including the inner aspect of the lips, cheeks, gums, tongue and throat. It is a type of mucositis. It can be acute or chronic, mild or serious.
Most mouth ulcers that are not associated with recurrent aphthous stomatitis are caused by local trauma. The mucous membrane lining of the mouth is thinner than the skin, and easily damaged by mechanical, thermal (heat/cold), chemical or electrical means, or by irradiation.
