Oral ulcers are painful sores that appear in the mouth and are characterized by defects in the epithelium, underlying connective tissue, or both. Most of them are harmless and resolve on their own, but they can be non-responsive and difficult to manage sometimes owing to their diversity of causative factors and clinical presentation.  Although many treatment options are in use for their treatment, this case report describes the use of3% citric acid mixed with lignocaine Jelly for the treatment of recurrent oral ulcers in a 70-year-old patient who was not responding to the conventional treatment.


Oral ulcers are considered as one of the most common problems that cause pain in the mouth [1]. The exact cause of mouth ulcers is still not known. But they may develop as a result of stress or anxiety, traumatic injuries, hormonal changes during pregnancy, puberty, and menopause. Deficiency diseases such as Crohn’s disease, vitamin B12 or iron deficiency, or a weakened immune system may all be considered as etiological factors for oral ulcers [2]. Any ulcerative lesion that lasts for two weeks or longer, is considered chronic and any ulcer of fewer than 14 days’ duration is considered Acute [3]. Recurrent ulcers usually present with a history of similar episodes with intermittent healing [4]. Most oral ulcers are usually harmless and resolve by themselves within a week or two. Sometimes, however, they can be non-responsive to conventional therapies, such as multi-vitamins and local analgesic jelly, or, in severe cases antibiotics and Analgesics [5]. The use of Citric acid (3%) has been reported to yield successful results in treating non-healing ulcers and a variety of infected wounds located at various parts of the body other than in the oral cavity [6]. Here we report a case of recurrent oral ulcers on the tongue which was treated with a mixture of 3% citric acid with 2% lidocaine jelly. Follow up of one year showed no recurrence.
