RESUMEN

OBJECTIVE: Oral ulcers are painful sores that appear in the mouth. Most of them are usually harmless and clear up on their own. Sometimes, they are non-responsive and difficult to manage. This report describes the case of an 80-year-old female patient with chronic oral ulcers of three years duration and which were refractory to conventional therapy. The ulcers were subsequently treated using 3% citric acid as a sole topical agent, applied three times a day that resulted in complete healing of oral ulcers by day 10 of treatment. The findings of this case report suggest that topical citric acid is a possible alternative treatment for chronic oral ulcers unresponsive to conventional treatment.
