Os pacientes foram divididos em 4 grupos: Controle; E-cig; Fumante e Ex-fumante. Os critérios de inclusão adotados foram: ausência de histórico de neoplasia maligna bucal e ausência de quaisquer sinais clínicos visíveis de alteração no local avaliado. Foi realizada avaliação quanto ao grau de dependência nicotínica, por meio do Teste de Fagerström para Dependênca à Cigarro e Escore de Consumo Situacional Issa, e quanto ao perfil tabágico dos pacientes. A mensuração de CO expirado foi utilizada como critério objetivo de avaliação de consumo de tabaco, bem como a concentração de cotinina no sangue capilar dos pacientes avaliados. As amostras foram coletadas por meio de citologia esfoliativa da região de bordo lateral de língua e soalho bucal. Os esfregaços obtidos foram fixados com spray alcoólico e as lâminas coradas pelo método de Feulgen. Posteriormente, foi realizada a investigação dos micronúcleos e das anomalias metanucleares. Para a comparação dos dados não paramétricos foram utilizados os testes Kruskal-Wallis e Mann-Whitney. Já para as correlações e associações entre os dados, foram utilizados o teste da correlação d...

The patients were divided into 4 groups: Control; E-cig; Smoker; and Former smoker. The inclusion criteria adopted were: absence of a history of oral malignancy and absence of any visible clinical signs of alteration at the evaluated site. An assessment was made of the degree of nicotinic dependence, using the Fagerström Test for Cigarette Dependence and the Issa Situational Consumption Score, and of the smoking profile of the patients. Measurement of expired CO was used as the objective criterion for the evaluation of tobacco consumption as well as the concentration of cotinine in the capillary blood of the evaluated patients. The samples were collected from the tongue lateral region and floor of the mouth by means of exfoliative cytology. The smears obtained were fixed with alcoholic spray and the slides were stained by the Feulgen method. Subsequently, the investigation of the micronuclei (MN) and metanuclear anomalies was carried out. For the non-parametric data, the KruskalWallis and Mann-Whitney tests were performed. For the correlations and associations between the data, the Spearman correlation test and the Fisher Exact Test were respectively used. A significance level of 5% was adopted for all tests. From the results, we observed a significant difference between groups E-cig and Control (p = 0.0072), and also between groups Smoker and Control (p = 0.0004), in the total of MN. In contrast, groups E-cig and Former smoker were similar, whereas the group of Smoker was significantly higher than Former smoker (p = 0.0370)..Resumo completo, clicar acesso eletrônico abaixo) / Mestre
