Abstract
Recurrent aphthous stomatitis (RAS) is an oral condition characterized by painful oral ulcerations. While the clinical features of this disease are easily defined, the etiology remains unclear. Thus, existing treatments are still unsatisfactory in reducing the severity, healing, and recurrence rate; however, there is no permanent and definitive treatment. Effective treatment for aphthous stomatitis is not available, and those treatments available mainly focus on suppressing its symptoms. We are reporting a case of a 17-year-old boy who presented with a 3-year history of multiple recurrent major ulcers in the oral cavity. Levamisole with steroids has been used in many clinical trials to treat aphthous ulcers, showing an improvement in pain, discomfort, healing time, and reduction in the number of ulcers. The same method was used to treat our patient, who showed promising results, with no recurrence for one year. Levamisole is a safe, easily tolerable and promising drug for the treatment of RAS.
