Abstract
Recurrent aphthous stomatitis (RAS), often referred to as canker sore, is a chronic inflammatory disease. Frequently seen in the primary care setting, RAS affects over 50% of the population and may be observed in an otherwise apparently healthy individual. An unknown pathogenesis and absence of curative treatment make RAS a challenge to manage. Treating RAS should be patient specific and focus on reduction of pain and lesions. An awareness of literature suggesting etiologies, precipitating, and predisposing factors can assist the practitioner and patient in controlling RAS episodes. Contained in this review is a suggested course of management for patients with RAS, including present recommendations for pharmacological interventions.
