An oral ulcer is a break in the continuity of the oral epithelium, caused by traumatic, chemical, thermal, electrical, or mechanical factors. This report presents the case of a 50-year-old male patient referred due to suspected oral cancer. The patient had undergone dental treatment on tooth 4.8, which fractured a month later, causing friction against the tongue. Three weeks later, an ulcer appeared and progressively increased in size. Clinical examination revealed an 11 × 8 mm ulcer on the right lateral border of the tongue, with elevated, indurated edges, keratotic areas, and a firm consistency. It was diagnosed as a traumatic ulcer caused by a sharp cusp. Treatment involved removing the causative factor and applying a solution containing Tannic Acid, Calcium Pantothenate, and Lidocaine (Bucozone) three times a day for five days. After seven days, the lesion had reduced to 5 × 3 mm and was asymptomatic. By day 14, the lesion had completely healed. This case highlights the importance of accurate diagnosis based on a thorough clinical history and examination, as oral ulcers can mimic malignant lesions and lead to incorrect treatment if not properly identified.
