Clinically, she presented with a painful ulcer on the lingual aspect of the posterior mandible and noticed a sharp bone which caused irritation to the side of the tongue. The exposed bone was removed surgically, and the ulcer was completely healed. Thus, emphasizing the understanding of the causative factors of oral ulcers can help in giving a proper treatment plan.enLingual Mucosal Ulceration, Bony Sequestration, Oral Ulceration, Bone DehiscenceArticle172082
