Recurrent aphthous ulcerative disease: presentation and management.

Recurrent aphthous ulceration (RAU) is the second most common type of ulceration seen in the oral cavity. Notwithstanding an extensive literature and numerous proposed aetiologies, the cause of the disease remains obscure. In addition to the current conservative management of RAU lesions with corticosteroids, new treatment options are available and some have proven successful in open trials. This paper reviews patient work-up and management.
