Aim To evaluate the bottom/top hardness ratio (B/T) and the dentin bonding stability of conventional and bulk-fill resin composites in high c-factor preparations. Methods Regular conventional (Tetric N-Ceram – TNC, and Polofil Supra – PFS), regular bulk-fill (Tetric N-Ceram Bulk fill – TBF, and Admira Fusion X-tra – AFX), and low viscosity bulk-fill resin composites (Tetric N-flow – TNF, and X-tra Base – XTB) were used to restore 180 dentin conical preparations. The specimens were randomly distributed in 12 groups (n = 15) according to the resin composites and storage time-points (24 h and six months) tested. After 24 h storage, all specimens were subjected to the bottom/top hardness ratio analysis. Then, the push-out bond strength test was performed in half of the specimens and the other half were maintained for six months on water storage before testing. The failure modes were analyzed in a stereomicroscopic. The data were analyzed statistically using one- and two-way ANOVA and Tukey post-test (p <0.05). Results There were no statistically significant differences for the bottom/top hardness ratio among the resin composites (p>0.05). Regardless of the storage time-point, regular bulk-fill resin composites showed the highest bond strength values statistically (p<0.05). Only conventional resin composites showed statistically lower bond strength values at six-month storage (p<0.05). Adhesive failures were more predominant for low-viscosity bulk-fill resin composites. Conclusion Although the DoC was not affected by different materials tested, only bulk-fill resin composites did not present dentin bond strength loss after six-month of water storage.

ABSTRACT Objective To Analyze and compare sustainable consumption habits in the clothing segment between Brazilians and Germans. Design/methodology/approach Descriptive, exploratory, and qualitative research. Interviews were conducted with 15 Germans and 15 Brazilians, aged between 20 and 32 years old, in order to identify consumption habits in the clothing segment, familiarity with the theme: sustainable consumption , and levels of personal awareness regarding their consumption behavior, applying the content analysis based on Bardin (2011) as a technique. Findings A significant difference between the two groups was found. While Germans presented greater knowledge on the subject, which was converted into embracing sustainable conduct in the clothing segment, Brazilians demonstrated to have a more superficial knowledge, besides presenting lower levels of awareness in their consumption and sustainable practices in the analyzed segment. Therefore, it concludes that Germans have greater access to information on the theme and more interest and familiarity with the subject. Consequently, it showed that it influences their consumption behavior, presenting habits towards environmental, social, and economic concerns in the clothing segment, habits that were not identified in the Brazilian sample group. Originality/value (mandatory) It contributes by providing an opportunity to comparatively analyze the habits and consumption of two distinct countries, helping entrepreneurs and managers to understand the market segments better and create more powerful strategies, focusing on the value perceived by the customer in the acts of consumption.

RESUMO Objetivo Analisar e comparar hábitos de consumo sustentável no segmento de vestuário entre brasileiros e alemães. Desenho/Metodologia/Abordagem Pesquisa descritiva, exploratória e qualitativa. Foram realizadas entrevistas com 15 alemães e 15 brasileiros, com idade entre 20 e 32 anos, a fim de identificar hábitos de consumo no segmento de vestuário, familiaridade com o tema consumo sustentável e níveis de consciência pessoal quanto aos seus hábitos de consumo empregando como técnica a análise de conteúdo baseado em Bardin (2011). Resultados Constatou-se uma diferença expressiva entre os dois grupos. Enquanto os alemães apresentaram maior conhecimento sobre o assunto, que se converteu na adoção de hábitos de consumo sustentável no segmento de vestuário, os brasileiros demonstraram ter um conhecimento mais superficial, além de apresentarem níveis menores de consciência de consumo e de práticas sustentáveis no segmento analisado. Conclui que os alemães têm maior acesso a informações sobre o tema e mais interesse e familiaridade com o assunto. Isso mostrou influenciar seus comportamentos de consumo, que apresentam hábitos no sentido de preocupação ambiental, social e econômica no segmento de vestuário, costumes esses não identificados no grupo amostral brasileiro. Originalidade/valor Contribui por oportunizar analisar comparativamente hábitos e de consumo de dois páises distintos, auxiliando empreendedores e gestores a conhecer melhor os segmentos de mercado e criar estratégias mais assertivas, atentando-se para o valor percebido pelo cliente nos atos de consumo.

Resumo O objetivo deste estudo foi avaliar a resistência de união, razão base/topo de microdureza, adaptação marginal e nanoinfiltração interfacial de resinas compostas bulk fill (BF) e tradicional (RT) de viscosidade regular.: Duas BF (Filtek Bulk Fill e Aura Bulk Fill) e duas RT (Filtek Z250XT e Aura) foram testados. Quarenta cavidades cônicas (4,8×2,8×4,0) foram preparadas em dentina bovina e restauradas com os compósitos (n=10). Depois de 24 h em água, a adaptação marginal foi avaliada por meio do corante com detector de cárie. As faces de topo e base das restaurações cônicas foram coradas por cinco segundos e a porcentagem de fendas na interface compósito/dentina foi determinada utilizando-se imagens analisadas num programa (ImageTool). A microdureza Vickers foi mensurada e a razção base/topo de microdureza (B/T) foi determinada. A resistência de união por push-out foi executada numa máquina de ensaios universal (0,5mm/min) e o padrão de fratura avaliado num estereomicroscópio (20x). Espécimes adicionais (n=3) foram confeccionados para avaliação da nanoinfiltração interfacial. Os dados foram analisados por meio de ANOVA a dois fatores e teste de Tukey (a=0,05). A porcentagem de fendas foi maior na base que no topo. A B/T da Aura Bulk Fill foi estatisticamente menor que os demais compósitos. A resistência de união por push-out foi similar entre os compósitos. As BF apresentaram menos nanoinfiltração que as RT na base das restaurações cônicas e não houve diferenças entre os materiais no topo. Conclui-se que a Filtek Bulk Fill comportou-se melhor que a Aura Bulk Fill considerando-se as propriedades analisadas.

Abstract The aim of this study was to evaluate the bond strength, bottom/top hardness ratio, marginal adaptation, and interfacial nanoleakage of regular viscosity bulk fill composites (RVBFC) and regular viscosity traditional composites (RVTC). Two RVBFC (Filtek Bulk Fill and Aura Bulk Fill) and two RVTC (Filtek Z250XT and Aura) were assessed. Forty conical cavities (4.8×2.8×4.0) were prepared in bovine dentin and restored with composites (n=10). After 24h in water, marginal adaptation was evaluated by staining with a caries detector. The top and bottom surfaces of the conical restorations were stained for five seconds and the gap percentage in the composite/dentin interface was determined using digital images on a measurement program (ImageTool). The Vickers microhardness was measured and the bottom/top microhardness ratio (B/T) was determined. Push-out bond strength test was performed in a universal testing machine (0.5mm/min) and failure modes were evaluated in a stereomicroscope (20×). Other specimens (n=3) were produced for interfacial nanoleakage evaluation. Data were analyzed using one and two-way ANOVA and Tukey’s test (α=0.05). The gap percentage was higher in the bottom compared to the top. The B/T ratio of the Aura Bulk Fill was statistically lower than other composites. Push-out bond strength were similar among composites. The RVBFC presented lower nanoleakage than the RVTC in the bottom of the conical restoration and there was no difference among the materials in the top surfaces. In conclusion, Filtek Bulk Fill performed better than Aura Bulk Fill regarding the analyzed properties.

As there was not any data on Chlamydia pneumoniae (TWAR) infections in Brazil so far, a prospective cohort study of adult patients hospitalized due to CAP was carried out for one year in a Brazilian university general hospital to detect the incidence of CAP by Chlamydophila pneumoniae (TWAR) for one year. During a whole year 645 consecutive patients hospitalized due to an initial presumptive diagnosis of respiratory diseases by ICD-10 (J00-J99), excluding upper respiratory diseases, were screened; 59 consecutive patients with CAP were diagnosed. They had determinations of serum antibodies to C. pneumoniae by microimmunofluorescence at the Infectious Diseases Laboratory of University of Louisville (KY, USA); 37 patients (63.8%) had seroreactivity to TWAR antigens, from which 23 (39.6%) had previous infection; 3 patients (5.2%) were diagnosed with CAP by TWAR and got cured. The incidence of TWAR CAP in our hospital by seroconversion was 5.2%. Our incidence of 5.2% is probably underestimated since TWAR culture was not available; we suggest that Real-Time PCR be used along with other diagnostic methods in future studies to detect the actual incidence of TWAR CAP. We propose that the serological criterion of IgM >1:16 alone to the diagnosis of acute infection by TWAR are discontinued due a lack of specificity.
