RESUMO Objetivos: identificar as evidências disponíveis na literatura sobre o conhecimento dos cirurgiõesdentistas quanto aos fatores de risco e diagnóstico precoce do câncer de boca e orofaringe. Métodos: trata-se de uma revisão integrativa da literatura. Foram realizadas buscas mediante os descritores e operadores booleanos na base de dados PubMed e LILACS, com uso de literatura cinza, nos idiomas inglês, espanhol e portugês. Resultados: dos 79 artigos do PubMed e 152 do LILACS, 24 foram selecionados. Destes, oito mostraram bom conhecimento dos dentistas, enquanto a maioria mostrou baixo ou pouco conhecimento sobre fatores de risco e diagnóstico precoce em dentistas. Todos os estudos, no entanto, destacam a necessidade de educação continuada para melhorar e manter o conhecimento sobre fatores de risco e diagnóstico precoce. Conclusões: grande parte dos cirurgiões-dentistas apresenta um conhecimento insuficiente sobre câncer de boca/orofaringe. É sugerida a educação continuada, visando melhorar o conhecimento e o diagnóstico precoce.

ABSTRACT Objectives: to identify the evidence available in the literature on the knowledge of dentists regarding risk factors and early diagnosis of oral and oropharyngeal cancer. Methods: it is an integrative review of the literature. Boolean descriptors and operators were searched in the PubMed and LILACS databases, using gray literature, in English, Spanish and Portuguese. Results: of the 79 PubMed and 152 LILACS articles, 24 were selected. Of these, eight showed good knowledge of dentists, while most showed low or little knowledge of risk factors and early diagnosis in dentists. All studies, however, highlight the need for continuing education to improve and maintain knowledge about risk factors and early diagnosis. Conclusions: most dental surgeons have insufficient knowledge of oral/oropharyngeal cancer. Continued education is suggested, aiming at improving knowledge and early diagnosis.

Abstract Objective: To investigate the involvement of young Brazilian students about five behaviors: tobacco use, alcohol consumption, sexual intercourse, knowledge about HPV, and knowledge about oral and oropharyngeal cancer. Material and Methods: Through a cross-section design, we explored some factors that might be associated with boys and girls. Statistical Regression methods were applied to identify differences, considering the estimation of the Odds Ratio. Results: Half of the sample had already consumed alcohol and at least 1 in 10 individuals had already tried smoking. One-third of adolescents have had sexual intercourse. Three factors related to boys were associated in the multiple regression analysis: have heard about HPV, have not heard about oral cancer, and think that HPV can cause oropharyngeal cancer. In conclusion, it seems that boys and girls were equally exposed to smoking-alcohol-sex; however, some differences were verified concerning the knowledge about HPV and oral / oropharyngeal cancer. Conclusion: Keep monitoring adolescents should be a priority to our study area, considering that those youngers had already being exposed to the risk factors for cancer.

Abstract: Geographic tongue is a chronic, inflammatory, and immune-mediated oral lesion of unknown etiology. It is characterized by serpiginous white areas around the atrophic mucosa, which alternation between activity, remission and reactivation at various locations gave the names benign migratory glossitis and wandering rash of the tongue. Psoriasis is a chronic inflammatory disease with frequent cutaneous involvement and an immunogenetic basis of great importance in clinical practice. The association between geographic tongue and psoriasis has been demonstrated in various studies, based on observation of its fundamental lesions, microscopic similarity between the two conditions and the presence of a common genetic marker, human leukocyte antigen (HLA) HLA-C*06. The difficulty however in accepting the diagnosis of geographic tongue as oral psoriasis is the fact that not all patients with geographic tongue present psoriasis. Some authors believe that the prevalence of geographic tongue would be much greater if psoriatic patients underwent thorough oral examination. This study aimed to develop a literature review performed between 1980 and 2014, in which consultation of theses, dissertations and selected scientific articles were conducted through search in Scielo and Bireme databases, from Medline and Lilacs sources, relating the common characteristics between geographic tongue and psoriasis. We observed that the frequency of oral lesions is relatively common, but to establish a correct diagnosis of oral psoriasis, immunohistochemical and genetic histopathological analyzes are necessary, thus highlighting the importance of oral examination in psoriatic patients and cutaneous examination in patients with geographic tongue.
