Morsicatio related white lesions of the tongue borders and lower lip: a case report
A 28-year-old woman was referred by her dentist to an oral and maxillofacial surgeon for white lesions of the lower lip and lateral tongue borders on both sides. The diagnoss morsicatio labiorum and linguarum was made. Cheek, tongue, and lip biting occurs with some regularity and often patients are unaware of this habit. The diagnosis of morsicatio is based on clinical appearance and additional diagnostics are unnecessary. The condition belongs to a subcategory of obsessive-compulsive disorders. Treatment is not always necessary, but may consist of making the patient aware of the cause, possibly combined with symptomatic and/or causal therapy, for instance with an occlusal splint or cognitive behavioral therapy.
