Fatores psicogênicos associados ao líquen plano bucal: revisão da literatura
Abstract
O Líquen Plano (LP) bucal é uma desordem mucocutânea crônica de origem inflamatória e de etiologia incerta. Distúrbios psiquiátricos têm sido freqüentemente relatados como fatores relacionados ao desenvolvimento do LP bucal. No entanto, esta associação ainda permanece controversa. O presente estudo pretende fazer uma revisão crítica da literatura a respeito deste assunto. Tem sido documentada a existência de desordens mentais em pacientes com LP bucal como ansiedade, depressão, estresse e outros, com índices de incidência consideráveis. Com base na literatura revisada sugere-se que certos distúrbios psicossomáticos podem ser fatores subjacentes ao LP bucal, porém, uma correlação direta entre estes fatores psicológicos e a doença permanece ainda pouco definida.
UNITERMOS: ansiedade; depressão; líquen plano; estresse; distúrbios psiquiátricos.
