Resumo
Diversos fatores etiológicos estão envolvidos na etiologia do carcinoma epidermóide oral, e dentre estes, o Papilomavírus Humano (HPV) tem sido extensivamente estudado nos últimos anos. O HPV é um vírus de DNA, epiteliotrópico, cujas propriedades oncogênicas estão relacionadas a interferências nos mecanismos que controlam a proliferação celular normal. Esses mecanismos são alterados principalmente pelas proteínas E6 e E7, que interferem nas funções normais das proteínas p53 e pRb, respectivamente. Os estudos envolvendo o HPV na carcinogênese oral são controversos. Assim, a associação entre esse vírus e o câncer oral ainda não está bem definida. O objetivo desse trabalho foi realizar uma revisão literária dos aspectos atuais relacionados ao HPV no câncer oral.
