Objective: To evaluate the use of facemasks by the Brazilian population during the COVID-19 pandemic. Materials and Methods: This cross-sectional study involved 1277 participants who answered a web-based open survey with questions about the use of facemasks during the COVID-19 pandemic. Descriptive statistics with percentages was performed, and the responses were analyzed with chi-square and independent t-tests. Results: A total of 1277 answered the questionnaire, and most participants were female (81.8%). Almost all the participants (99.1%) reported wearing facemasks, and 34.2% are wearing just because it is mandatory; 65.8% would continue to wear masks even if it was not mandatory. Most subjects (50.4%) believe that masks' use effectively prevents infection by the novel coronavirus. Reusable fabric facemasks are the most used by the participants (49.5%). Almost all subjects were wearing masks to go to crowded and public places. Most respondents (67.3%) are bothered with the use of facemasks, and the most cited reason for the discomfort was feeling trapped or suffocated (58.9%). Discussion: The use of facemasks can help prevent the COVID-19, but it is most effective at reducing the spread of the virus when the general population's compliance is high. Some factors that limit the population's compliance with the use of masks are discomfort and a sense of embarrassment. Media campaigns and public health promotion activities supported by governmental agencies can increase the use of facemasks by the population. Conclusion: The mean level of anxiety with the COVID-19 pandemic was 6.18. Almost all the participants were wearing facemasks, and they believe that its use effectively prevents infection by the novel coronavirus. Reusable fabric facemasks are the most used by the participants. Almost all subjects were wearing masks to go to crowded and public places. The great majority of the participants feel more protected with the use of facemasks.

Background To evaluate the impact of the use of face masks on oral hygiene habits; oral conditions self-perception; reasons to seek dental treatment; and esthetic concerns. Material and Methods 1346 participants answered a web-based survey with questions related to the aims of the study. Descriptive statistic was performed and the responses were analyzed with chi-square test and regression analysis. Results With the use of masks, toothbrushing frequency decreased significantly, and people are significantly less concerned about oral hygiene. The number of subjects that reported to have halitosis increased significantly and this was associated with a decrease in toothbrushing frequency. The greatest complaints of subjects were teeth color and alignment. The prevalence of bruxism increased significantly. Overall, 94.1% considered that esthetics is important to seek dental care even with the use of masks, and 84.2% are maintaining usual periodic dental care. People are significantly less concerned with their smile and dental esthetics with the use of masks. Conclusions With the use of face mask, people must be motivated regarding maintaining oral hygiene habits. Some respondents will seek dental care only when masks were no longer necessary, therefore dentists must be aware of a reduction in the volume of patients. Key words: Dental health surveys, esthetics, oral hygiene, dental care, COVID-19, behavior.

This paper evaluates the effect of an additional hydrophobic resin coat (extra HL) associated with universal adhesives on sound and eroded dentin and evaluated immediately or after 2 years of water storage to improve the microtensile bond strength (μTBS) and nanoleakage (NL) when compared to the use of universal adhesives only. Sixty-four molars were assigned to eight groups using the following combinations: 1. dentin substrate, including sound and eroded dentin; 2. treatment, including the control and extra HL and storage time (immediately and after two-years of storage). Two universal adhesives (Prime & Bond Active or Scotchbond Universal) were evaluated. Before restoration, half of the teeth were subjected to soft-drink erosion. Composite buildups were bonded; specimens were stored (37 °C/24 h), sectioned into resin–dentin bonded sticks and tested for microtensile bond strength and nanoleakage using SEM (immediately and after two-years of storage). Three-way ANOVA and Tukey’s test (α = 0.05%) were used. In the immediate testing, the application of extra HL did not increase microtensile bond strength values compared with the control group in either substrate (p > 0.05). However, extra HL significantly decreased nanoleakage values when applied to eroded and sound dentin (p = 0.0001). After two years, the application of extra HL produced significantly higher microtensile bond strength and lower nanoleakage values than the control group for both adhesives (p = 0.0001). In all cases, sound dentin showed higher microtensile bond strength and lower nanoleakage values than eroded dentin (p = 0.000001). An extra HL increased the bond strength and reduced nanoleakage in eroded dentin after two-years of storage.

O objetivo deste trabalho foi demostrar a importância da correta conduta do cirurgião-dentista no atendimento inicial, deteção e notificação de casos de mulheres vítimas de violência doméstica, bem como seu papel na reabilitação oral. Este trabalho foi classificado como uma revisão integrativa da literatura de pesquisa descritiva e abordagem qualitativa. Os levantamentos bibliográficos foram feitos através de bases de dados online, destacando-se, Pubmed, BBO, ABOL e Scielo. Foram selecionados artigos publicados entre 2010 e 2021 nos idiomas português e inglês. As pesquisas comprovam que as raízes da violência de gênero são profundas, pois advém de uma construção social patriarcal. Após a análise, a revisão de literatura demostrou que os profissionais fazem encaminhamentos inadequados, encaminhando apenas para um serviço/profissional (principalmente Delegacia de Defesa da Mulher ou psicólogo), sem acompanhar o caso, o que é considerado insuficiente em casos de violência contra mulher, além de ir contra o princípio de integralidade. Conclui-se que os profissionais de saúde não possuem uma conduta satisfatória com pacientes vítimas de violência doméstica, tanto na detecção de casos como na notificação, principalmente por despreparo, desconhecimento e desconfiança da resolutividade dos casos pelo serviço público, sendo necessária a implementação de debates sobre o assunto nos ambientes acadêmicos e profissionais.
