Modificação de forma e dimensões dos arcos superior e inferior obtidas em modelos de estudo após expansão rápida da maxila com o aparelho hyrax

The aim of an orthodontic treatment is the achievement of a balanced, esthetic and, most of all, stable, intra and inter arches relationship. A common problem observed in occlusion is posterior crossbite and atresic maxilla. This problem may be treated by slow expansion, rapid expansion or surgically assisted expansion. For the present study cast models of 14 children between 7 and 11 years old were evaluated. There were 7 male and 7 female subjects that presented posterior crossbite and needed rapid maxillary expansion. The Hyrax appliance performed the therapy for correction of this transversal alteration, which is a common possibility in the treatment of this malocclusion. It was observed that the distance between the upper first molars and upper cuspids increased significantly; the length of the upper arch decreased and its perimeter increased significantly. At the lower arch there were no dimensional changes.

Efeito das dimensões dos corpos de prova na resistência à flexão de compósitos restauradores

The aim of this study was to evaluate the influence of specimen size, in comparison with the ISO Standard, on the three point flexural strength of resin composite restorative materials Filtek Supreme and Filtek Z-250. Forty specimens were fabricated for each material with the following length, width and thickness measurements (n = 10): 1) 20 × 2 × 2 mm (ISO 4049); 2) 10 × 2 × 1 mm; 3) 10 × 1 × 1 mm; 4) 8 × 0.8 × 0.8 mm. The composites were inserted in a single increment into two-piece metal device and light-polymerized. The specimens were dry stored at 37 ± 1 °C and protected from light for 7 days. After this period, flexural strength was measured by three-point flexure test using MTS 810 equipment, with a load cell of 10 kN at a speed of 0.5 mm/min. For the evaluated sizes, the results showed significant variability (p = 0.00) with values when compared with the ISO Standard (116.700 MPa), being statistically higher for the test specimens measuring 10 × 1 × 1 mm (142.530 MPa), similar for those of 10  ×  2  ×  1  mm (115.815 MPa) and lower for those of 8 × 0.8 × 0.8 mm (86.650 MPa). There was statistical equality (p = 0.08) for the studied composites (Filtek Supreme, 125.270 MPa; Filtek Z-250, 108.130 MPa). Specimens measuring 10 × 2 × 1 mm provided flexural strength values equivalent to those obtained in the sizes recommended by the ISO 4049 standard, with lower consumption of material, energy and time.

Dimensões das furcas de primeiros pré-molares superiores e sua relação com curetas periodontais

The aim of this in vitro study was to comparatively evaluate the mesio and distal furcation entrance measurements of first maxillary premolar. The measurements were compared with different curette blades. A caliper was used by an examinator to acquire the measurements of root trunk (TR); 1 mm (D1) and 2 mm (D2) both below the furcation entrance. For this study Gracey, Mini Gracey, Padua Lima (PL) and Goldman Fox 4 curettes (Millenium) were selected. Measurements of DT - total distance of the active blade length, DI - width of the active blade, DM - width of the medium part of the active blade were obtained for the curettes. The measurements were obtained in both the coronary face and in the lateral face. The data TR, D1 and D2 presented normal distribution and were statistically analyzed by paired t-test. Statistically significant differences were found in the mesial root trunk region (TR) of both premolars. The mean of the measurements was greater than the distal. Mean and standard deviation were obtained, and both Gracey and Mini Gracey showed mean measurements compatible with the closer furcation entrance (D1 - 1 mm). Goldman Fox 4 showed adaptation only in the mesial face, and Padua Lima showed no access to any of the faces. Thereby it is concluded that the access of the furcation is narrow (D1). The mesial face of the root trunk (TR) showed mean measurement greater than distal face. Gracey and Mini Gracey curettes demonstrated to be compatible for both faces, mesial and distal of the first maxillary premolars studied.

Estimativa da altura por dimensões dentárias: uma revisão da literatura

The knowledge of Forensic Anthropology is very importance in cases of identification of human remains. One phase of this process is the study of human height, which can be accomplished with relative ease when intact corpses, complete skeletons or long bones are available. However, the experience of Forensic Dentistry is essential in situations in which there is only information of the skull or of the teeth. The objective of this study was to review in the literature and evaluate works concerning the estimate of the height calculated from dental dimensions. Carrea, in 1920, proposed the estimation of the probable height of an individual by developing formulas for maximum and minimum heights from measurements of the lower central and lateral incisors and canines. The method was used in the case "Josef Mengele", to complement estimates. Tested in the Brazilian population, 70% of match between the actual and the estimated stature were obtained. Using more precise instruments, in the modified method, 96% of correct matching were verified. Recently, a new formula was introduced to estimate height, from measurements of upper teeth, because the technique cannot be used when jaw is not available. The correlation between height and dental dimensions is demonstrated. However, there is still a lack in scientific literature in this field, and further studies are necessary. The estimate of height from dental dimensions can be very useful and important, especially in situations where the complete skeleton it not found, and long bones are not available.

Histórias de uma antiga relação: uma compreensão da presença dos conteúdos mitológicos na construção do pensamento psicanalítico de Sigmund Freud

The use of mythology as a resource in the construction of Freudian thought and contributions relevant to the use of these outbreaks are of relevance to the development of psychoanalytic studies. This is primarily to discuss the design and conceptualization of myth and mythology, the following route through the Freudian and understand the various arguments used by the author to connect the mythology in the construction of psychoanalysis, psychoanalytic thought, trying to highlight the aspects of this connection and opportunities for reflection and understanding of psychoanalytic concepts that the mythological narratives provide.

Efeitos da adição de agentes tróficos na dieta de leitões desmamados sobre a expressão da enzima ornitina descarboxilase, os conteúdos de proteína e DNA e o desempenho

Two experiments were carried out to evaluate the effect of adding glutamine, fish oil or yeast cellular wall to the diet of weaned piglets on the expression of the enzyme ornithine decarboxylase (ODC), the protein content and DNA in small intestine samples and on performance. In the first experiment, 24 weaned piglets were used to measure the performance at the phases prestarter, starter 1 and starter 2. Four diets were tested (T1 -basal diet (BD); T2 -BD + 1% of glutamine; T3 -BD + 0,2% of yeast cellular wall; T4 -BD + 5% of fish oil). At the second experiment 45 weaned piglets were used and distributed in a randomized block design, in factorial outline with four diets and three slaughter ages (on the day of weaning, on the seventh and fourteenth days postweaning). The tested diets did not alter the piglets' performance in none of the phases. There was reduction of the expression of the ODC enzyme, of the protein concentration and of the relationship protein/DNA to the seven days postweaning, with increase of the values on the 14th day, evidencing a state of hypotrophy of the mucous membrane, suggesting that the process of protein synthesis in the small intestine was diminished in the first week after weaning, but it presented recovery signs in the second week.

As dimensões geográficas dos Arranjos Produtivos Locais

This article aims to further discuss the Local Productive Arrangements (APLs), considering some geographical visions thinking about spatial configuration and the economic and social processes that characterize them, configuring a wide range of territorialities and productive territories that mark the landscape current Brazilian. In this sense, APLs are present today in both the figure of those who study analytical concept for regional development, and as a public policy supporting networks and supply chains in their territorial bases, especially small businesses. Thus, this arrangements can be read, geographically, as territorial productive specializations that are configured in spatial circuits of production, integrated with other regions, localities and supply chains through the morphology of networks and districts and grounded in networks of urban networks of material and immaterial flows which are bringing urban centers of different sizes. Considering the multidimensionality of the subject, the clusters have certain weaknesses in terms of their assumptions and perspectives, especially the limitations of the tool if designed just for resources and policies applied at the local level. Suggest the approach of a "geography of APLs" is to seek treat it from a territorial and socio reading.

A educação física no ENEM: análise dos conteúdos das questões de educação física nas provas do ENEM de 2009-2012

A Educação Física sofreu tentativas de mudanças desde surgimento até os dias de hoje, sobretudo no espaço escolar. Podemos observar esse fenômeno desde o final da década de 1980 onde surgiram inúmeras publicações de livros e artigos abordando tal tema, que iam contra uma Educação Física voltada para o militarismo e o tecnicista. Essas ideias atingiram o auge na década de 1990 e ainda estão fortemente presentes e marcadas por debates e defesas de ideias. Essas tentavam explicar o ser humano como um todo em seus diferentes aspectos - cognitivos, sociais, afetivos, motores e culturais, por meio do movimento, pois se sabe que a Educação Física é a área do conhecimento que estuda o se movimentar do ser humano e o diálogo que ele exerce com o mundo. Dessa forma esse trabalho busca analisar os conteúdos das questões do ENEM de 2009, 2010, 2011 e 2012 e identificar quais são as concepções que aparecem nas questões, de modo a compreender o que o Exame acredita ser considerado importante para o aluno aprender na educação física escolar. Para o desenvolvimento desta pesquisa usaremos como material as questões da prova do ENEM de 2009 a 2012 e realizaremos uma análise do conteúdo buscando assim descrever e interpretar o conteúdo das questões selecionadas. Entende - se que a análise do conteúdo baseia-se nas ações de comparação e de classificação textuais, ou seja, no entendimento de semelhanças e diferenças
