Abstract
OBJECTIVE: To evaluate the type and frequency of self-mutilation lesions of the mouth and lips in a large group of institutionalized mentally retarded subjects. SUBJECTS AND METHODS: Two hundred and forty-five institutionalized mentally retarded patients were evaluated clinically by a systematic inspection of the perioral cutis, lips, tongue, oral mucosa, palate, gingivae and teeth. Moreover, the drug therapy taken by each patient was carefully reviewed. RESULTS: Numerous lesions were found involving the tongue, lips, oral mucosa, perioral skin, gingivae and teeth, prevalently supported by a self-mutilation mechanism (such as cheek and tongue biting and nodular traumatic lesions), which were differentially expressed in patients with different degrees of mental retardation. A possible effect of anti-epileptic or neuroleptic drugs was also detected. CONCLUSIONS: These findings indicate that inspection of the oral cavity should always and carefully be performed in all patients with mental retardation and in those with neuroleptic and anti-epileptic drug therapy, in order to avoid or even extinguish self-mutilation of the oral cavity by means of an accurate hydration of the mucosa which might counterbalance some iatrogenic undesired effects.
