Abstract(s)
Ao Médico Dentista cabe o diagnóstico e o tratamento de todas as perturbações que
afetem a cavidade oral e estruturas anexas e, embora a cavidade oral seja uma zona de
fácil visualização e acesso, as alterações que vão acontecendo passam muitas vezes
despercebidas, ou não lhes é dado o devido valor fazendo com que, as patologias
malignas sejam na maior parte das vezes, reconhecidas tardiamente não permitindo
outro tipo de atuação senão paliativa.
Uma das desordens que acontecem com recorrência é o Líquen Plano (LP). Tratando-se
de uma patologia crónica, mucocutânea e autoimune, relativamente comum, que afeta
maioritariamente as mulheres numa proporção de 3:2 para os homens, em idades
compreendidas entre os 50 e 70 anos de vida. É uma dermatose caracterizada por ter
potencial de recorrência, não sendo, contudo, contagiosa. O Líquen Plano poderá atingir
a pele, couro cabeludo, unhas, mucosa genital e a cavidade oral. Na cavidade oral,
designa-se como Líquen Plano Oral (LPO) e afeta a mucosa oral em 70% dos casos,
sendo descrita pela Organização Mundial da Saúde (OMS), como sendo uma lesão prémaligna.
Tendo em conta estes fatores, o objetivo deste trabalho é a análise da potencialidade de
malignidade do LPO, uma vez que, existem distintas vertentes de entendimento e
caracterização do mesmo.
Para tal foi utilizada uma metodologia qualitativa de natureza bibliográfica com a
aplicação de um conjunto de dados de pesquisa em websites, artigos de revistas e obras
de índole cientifica, permitindo assim a realização de uma revisão bibliográfica.
Compete at the Dentist the diagnosis and treatment of all disorders affecting the oral cavity and associated structures, and although the oral cavity is a zone of easy viewing and access, the changes that are happening often go unnoticed, or not to them given the proper value causing the malignancies are the most often recognized later disallowing other type of treatment then palliative. One of the disorders that occur with recurrence is Lichen Planus (LP). Is a chronic, mucocutaneous and autoimmune disease that is relatively common, affecting mainly women in a ratio of 3: 2 for men, in age between 50 and 70 years. It is a dermatosis characterized by having potential for recurrence however, it isn´t contagious. Lichen Planus may reach the skin, scalp, nails, genital mucosa and oral cavity. In the oral cavity is referred to as Oral Lichen Planus (OLP) affecting the oral mucosa in 70% of cases and is described by the World Health Organization (WHO), as a premalignant lesion. Given these factors, the aim of this work is the analysis of OLP of malignancy potential, since there are different aspects of understanding and characterization of the same. For this we used a qualitative methodology of bibliographical with the application of a set of research data on websites, magazine articles and works of scientific nature , thus enabling the realization of a literature review.
