Self-Mutilation of Tongue and Lip in a Patient with Simple Schizophrenia

Self-inflicted lesions that cause mutilation are observed in schizophrenic patients. This case report describes the diagnosis and treatment of simple schizophrenia in a 31-year-old male patient who bit his own tongue and lower lip. The dental treatment proposed included the construction of a splint to prevent new lesions and to allow healing of existing ones. The treatment afforded to avoid tooth extraction before the patient responded to psychiatric drug treatment. The importance of a transdisciplinary approach to self-mutilation due to psychiatric disorders is stressed. The interaction between the two teams, stomatology and psychiatry, was crucial for the improvement of the patient's condition.
