Introdução: O aumento da demanda pela odontologia estética guiou o desenvolvimento de resinas compostas com melhores propriedades físicas e mecânicas. Por isso, percebe-se que há atualmente disponibilidade de uma grande variedade desse material. Dessa forma faz-se necessário a realização de estudos científicos acerca das resinas composta. Objetivo: Avaliar comparativamente, in vitro, à resistência de duas resinas compostas fotopolimerizáveis encontrados no mercado: a Filtek Z350 XT da 3M e a Zirconfill da Technw, após teste mecânico de compressão e análise estatística dos resultados. Material e método: Quatro amostras de cada resina composta foram submetidas ao teste de resistência à compressão numa máquina de ensaio universal. Os resultados foram analisados estatisticamente através do teste de Mann-Whitney com margem de erro 5.0%. Para digitar os dados e obter os cálculos estatísticos foi utilizado o programa IBM SPSS na versão 23. Resultados: A média da força foi mais elevada na resina Zirconfill do que na resina Z350; entretanto, a mediana foi mais elevada na resina Z350. Para a margem de erro fixada (5,0%) não há comprovação de diferença significativa (p > 0,05) entre as duas resinas em relação à força de resistência analisada. Conclusão: As resinas compostas testadas mostram valores de resistência a compressão semelhantes e não apresentam diferenças relevantes.Descritores: Resinas Compostas; Nanotecnologia; Odontologia.ReferênciasBowen RL.

Introdução: Dentes que passaram por tratamento endodôntico e que perderam parte da estrutura dentária devido cárie, geralmente, necessitam de retentores intrarradiculares para promover retenção. Os padrões estéticos atuais, que buscam um sorriso de cor natural e alinhado, ocorreram nos últimos anos devido rápida evolução no que se diz respeito às resinas compostas. Objetivo: Reunir todas as vantagens desses biomateriais para reabilitar, harmonicamente, um pré-molar superior. Relato de Caso: Paciente procurou atendimento odontológico Odontominas para tratamento endodôntico do elemento 25 e após conclui-lo realizar reabilitação estética com pino de fibra de vidro e resina composta em consenso com o paciente após planejamento. Respeitando o princípio de desobturação de 2/3 do canal radicular para inserção do pino com posterior reabilitação em resina composta, o pino foi cimentado com cimento resinoso Allcem dual na cor A2 FGM com auxílio do Lentulo Nº 35, após ser preparado e adaptado ao conduto radicular. Posteriormente, o núcleo de preenchimento foi confeccionado e acabado com ponta diamantada 2135F KG Sorense e condicionado com ácido fosfórico a 37% por 30 segundos, seguido do adesivo Single Bond 2 3M/ESPE e foto ativado por 30 segundos. A subsequente reconstrução coronária foi realizada com pequenos incrementos fotopolimerizando cada camada, com sistema de resinas Z350 3M/ESPE para dentinana cor A3 e esmalte na cor A2. O pré-acabamento, foi realizado com ponta diamantada 2135F KG Sorensen e discos tipo sof-lex 3M/ESPE. O polimento da restauração foi feito após 48 horas, ponta de polimento Pogo Disco Dentsply e pasta própria para polimento.Descritores: Materiais Dentários; Estética Dentária; Odontologia.ReferênciasBehr M, Proff P, Kolbeck C, Langriegr S, Kunze J, Handel G et al.

Various authors have emphasized the spatial information resident in an electron micrograph taken with adequately coherent radiation. In view of the completion of at least one such instrument, this opportunity is taken to summarize the state of the art of processing such micrographs. We use the usual symbols for the aberration coefficients, and supplement these with £ and 6 for the transverse coherence length and the fractional energy spread respectively. He also assume a weak, biologically interesting sample, with principal interest lying in the molecular skeleton remaining after obvious hydrogen loss and other radiation damage has occurred.

Cellular organic structures such as wood can be used as scaffolds for the synthesis of complex structures of organic/ceramic nanocomposites. The wood cell is a fiber-reinforced resin composite of cellulose fibers in a lignin matrix. A single cell wall, containing several layers of different fiber orientations and lignin content, is separated from its neighboring wall by the middle lamella, a lignin-rich region. In order to achieve total mineralization, deposition on and in the cell wall must be achieved. Geological fossilization of wood occurs as permineralization (filling the void spaces with mineral) and petrifaction (mineralizing the cell wall as the organic component decays) through infiltration of wood with inorganics after growth. Conversely, living plants can incorporate inorganics into their cells and in some cases into the cell walls during growth. In a recent study, we mimicked geological fossilization by infiltrating inorganic precursors into wood cells in order to enhance the properties of wood. In the current work, we use electron microscopy to examine the structure of silica formed in the cell walls after infiltration of tetraethoxysilane (TEOS).

Instrument Control

Over the past few years it has become apparent in our multi-user facility that the computer system and software supplied in 1985 with our CAMECA CAMEBAX-MICRO electron microprobe analyzer has the greatest potential for improvement and updating of any component of the instrument. While the standard CAMECA software running on a DEC PDP-11/23+ computer under the RSX-11M operating system can perform almost any task required of the instrument, the commands are not always intuitive and can be difficult to remember for the casual user (of which our laboratory has many). Given the widespread and growing use of other microcomputers (such as PC’s and Macintoshes) by users of the microprobe, the PDP has become the “oddball” and has also fallen behind the state-of-the-art in terms of processing speed and disk storage capabilities. Upgrade paths within products available from DEC are considered to be too expensive for the benefits received. After using a Macintosh for other tasks in the laboratory, such as instrument use and billing records, word processing, and graphics display, its unique and “friendly” user interface suggested an easier-to-use system for computer control of the electron microprobe automation. Specifically a Macintosh IIx was chosen for its capacity for third-party add-on cards used in instrument control.

Abstract The purpose of this article is to provide clinical supervisors with information pertaining to state-of-the-art clinic observation technology. We use a novel video-capture technology, the Landro Play Analyzer, to supervise clinical sessions as well as to train students to improve their clinical skills. We can observe four clinical sessions simultaneously from a central observation center. In addition, speech samples can be analyzed in real-time; saved on a CD, DVD, or flash/jump drive; viewed in slow motion; paused; and analyzed with Microsoft Excel. Procedures for applying the technology for clinical training and supervision will be discussed.

This paper is an introduction to behavioral genetics for researchers and practioners in language development and disorders. The specific aims are to illustrate some essential concepts and to show how behavioral genetic research can be applied to the language sciences. Past genetic research on language-related traits has tended to focus on simple etiology (i.e., the heritability or familiality of language skills). The current state of the art, however, suggests that great promise lies in addressing more complex questions through behavioral genetic paradigms. In terms of future goals it is suggested that: (a) more behavioral genetic work of all types should be done—including replications and expansions of preliminary studies already in print; (b) work should focus on fine-grained, theory-based phenotypes with research designs that can address complex questions in language development; and (c) work in this area should utilize a variety of samples and methods (e.g., twin and family samples, heritability and segregation analyses, linkage and association tests, etc.).
