Marginal adaptation of class II cavities restored with bulk-fill composites

Objectives: To determine the marginal adaptation of bulk-fill composites in class II MO cavities.Methods: Standardized class II MO cavities with bevelled enamel margins were prepared in 40 extracted human molars. The teeth were randomly assigned to one of the five experimental groups (n = 8). The teeth were restored with two horizontal increments of composite (4 mm and 2 mm thickness). The experimental groups were (1st/2nd increment): Gr. A - Venus Bulk-Fill/Venus Diamond; Gr. B - Tetric EvoCeram BulkFill/Tetric EvoCeram; Gr. C - Surefil SDR/Ceram-X; Gr. D - SonicFill; Gr. E - Ceram-X/Ceram-X (control). After finishing procedures, impressions were made using a polyvinyl siloxane and epoxy resin replicas were obtained. Thermo-mechanical stressing was carried out 24 h after the restorative procedure. All specimens were submitted to 240,000 occlusal loading and simultaneous 600 thermal cycles in water at 5 degrees C and 50 degrees C. After loading, a new set of epoxy resin replicas was obtained. Scanning electron microscopy was carried out at 200x magnification. Results for the marginal adaptation were expressed as percentages of continuity relative to the exposed interface and analyzed by ANOVA and Duncan post hoc test (p < 0.05).Results: In enamel, no significant differences were detected before and after thermo-mechanical loading between groups. In dentine, the worst results were observed in Gr. A.Conclusion: By applying simple layering techniques, bulk-fill materials do not allow better marginal adaptation than a standard composite. Clinical significance: A new class of resin-base composite (bulk-fill) was recently launched on the market. The bulk-fill composites exhibited adequate marginal adaptation and similar to the results of the standard composite. (C) 2014 Elsevier Ltd. All rights reserved.

Educação Profissional e Ideologia das Competências: Elementos para uma Crítica da Nova Pedagogia Empresarial sob a Mundialização do Capital

This article aims to address the relationship between work and professional education, specifically the ideology skills and the new pedagogy business under the globalization of capital. Is analyzed at first, the world-historical context, the restructuring of the productive and political capital from the 1970s, and the demand for a new organization of work based on model Toyota. Second, discuss such changes are productive within the Brazilian state and its influence on educational policies geared to work, permeated by the ideology skills as an instrument that seeks to obscure the relationshipcapital. It discusses the emergence of new education business connected to the ideals of human capital. It is the influence of international organizations in Brazil of the United Nations (UN) and the United Nations Organization for Education, Science and Culture (UNESCO), aimed at articulating the education according to the ideological aspect global, verified legislative apparatus in education. Ends up not only to reflect the content of the skills ideology, but it is suggested the redemption value of the denied promise of emancipation human-general.
