Este livro traz reflexões a partir de ideias e teorias produzidas e difundidas pelo Núcleo de Estudos de Direitos Alternativo (Neda) e pelo Núcleo de Estudos da Tutela Penal e Educação em Direitos Humanos (NETPDH), ligados à Faculdade de Ciências Humanas e Sociais da Unesp, em Franca. Ambos os grupos são reconhecidos nos meios acadêmicos do Direito por desenvolverem uma visão crítica acerca de tutela penal, que seria permeada pela seletividade e desproporcionalidade, além de provocar estigmatização, reunindo, assim, traços marcantes do sistema penal brasileiro. De acordo com o prefácio do professor de Direito Penal e Criminologia da Unesp, Paulo César Corrêa Borges, o autor, Roberto Galvão Faleiros Junior, apresenta aqui reflexões da criminologia crítica que estabelecem uma compreensão conjuntural dos sistemas penais (particularmente o do Brasil).Tais reflexões indicam, segundo Borges, proposições concretas para a instrumentalização democrática do direito penal na América Latina, levando em conta os pressupostos materiais, históricos e dialéticos comprometidos com a formulação de concepções a partir das classes subalternas e marginalizadas, mas também com limitações referentes à compreensão dos direitos humanos

OBJECTIVE: To determine the prevalence of mesiodens in deciduous and mixed dentitions and its association with other dental anomalies. MATERIAL AND METHODS: Panoramic radiographs of 1,995 orthodontic patients were analyzed retrospectively, obtaining a final sample of 30 patients with mesiodens. The following aspects were analyzed: gender ; number of mesiodens; proportion between erupted and non-erupted mesiodens; initial position of the supernumerary tooth; related complications; treatment plan accomplished; and associated dental anomalies. The frequency of dental anomalies in the sample was compared to reference values for the general population using the chi-square test (c²), with a significance level set at 5%. RESULTS: The prevalence of mesiodens was 1.5% more common among males (1.5:1). Most of the mesiodens were non-erupted (75%) and in a vertical position, facing the oral cavity. Extraction of the mesiodens was the most common treatment. The main complications associated with mesiodens were: delayed eruption of permanent incisors (34.28%) and midline diastema (28.57%). From all the dental anomalies analyzed, only the prevalence of maxillary lateral incisor agenesis was higher in comparison to the general population. CONCLUSION: There was a low prevalence of mesiodens (1.5%) in deciduous and mixed dentition and the condition was not associated with other dental anomalies, except for the maxillary lateral incisor agenesis.

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.
