Traumatic ulcer in patient with obsessive-compulsive disorder: a case report

Traumatic ulcers are common oral mucosal lesions primarily caused by mechanical trauma, typically presenting as solitary lesions with low recurrence rates.However, when associated with psychiatric disorders, these ulcers can become extensive and multiple.This study details a case of multiple traumatic ulcers in a 25-year-old male patient with obsessive-compulsive disorder focusing on characteristics and treatment process.Three months prior the patient began biting his tongue due to itching, leading to severe ulcers from uncontrollable repeated biting.Histopathological examination excluded reactive lesions, infectious diseases, and malignancies, confirming the diagnosis of a traumatic ulcer.Treatment included systemic and topical corticosteroids, behavioral modification therapy, and oral appliance use.Despite a significant reduction in ulcer severity, poor compliance with oral appliances resulted in incomplete healing and recurrence.This case highlights the impact of psychiatric disorders on the development and exacerbation of traumatic ulcers, underscoring the importance of proper diagnosis and treatment by dental professionals.
