MTA e hidróxido de cálcio como materiais obturadores de canal radicular em reimplante tardio de dente de macaco

O tratamento endodôntico é uma etapa importante do protocolo de atendimento do reimplante dentário e tem uma relação direta com o aparecimento das reabsorções radiculares, maior causa de perda dos dentes reimplantados. O objetivo do trabalho foi analisar o processo de reparo no reimplante tardio de dente de macaco, utilizando o hidróxido de cálcio (Ca(OH)2) e o MTA como materiais obturadores de canal. Cinco macacos Cebus apella adultos tiveram seus incisivos laterais superiores e inferiores, direito e esquerdo, extraídos e deixados em meio ambiente por 60 minutos. Decorrido esse período, foi realizado o preparo biomecânico dos canais e os dentes foram divididos em dois grupos experimentais: grupo I - canal preenchido com pasta de Ca(OH)2 e grupo II - canal preenchido com MTA (Angelus®). Após o selamento da abertura coronária com ionômero de vidro, o ligamento periodontal foi removido e os dentes imersos em solução de fluoreto de sódio 2%, pH 5,5, por 10 minutos. Em seguida, os alvéolos foram irrigados com soro fisiológico e os dentes reimplantados e contidos por 30 dias com fio de aço e resina composta. A eutanásia dos animais foi realizada 60 dias após o reimplante. Os espécimes de ambos os grupos apresentaram reabsorção por substituição e pontos de anquilose ao longo dos três terços radiculares e ausência de reabsorção inflamatória. Não houve diferença significante entre os dois grupos com relação à reabsorção por substituição, porém a quantidade de anquilose foi significativamente maior no grupo do Ca(OH)2. Baseado nesses resultados conclui-se que o MTA pode ser uma opção clínica viável para a obturação de dentes tardiamente reimplantados que necessitam de um longo período de curativo com hidróxido de cálcio.

Análise paleogeográfica evolutiva da região do Parque Estadual da Ilha do Cardoso (PEIC), litoral sul de São Paulo, como subsídio a ações de planejamento e conservação ambiental

Cardoso Island, settled in the south of paulista region, is characterized by its ecological importance due to the great biodiversity of Mata Atlântica and for accommodating several kinds of ecosystems as mangroves, which were considered by UNESCO as human natural ownership. The mangroves are among the most important marine ecosystems, known as warranty of biological productivity and diversity and supply of food and economical resources to the local population. Although the island has been transformed in a state park for preservation, it hasn’t become free from environmental impacts made by antropical activities. This way it was proposed a rebuilt of an evolutionary process in the region, having as an objective to subsidize programs of environmental conservation and planning , aiming to a sustainable development. For this it was used a isobasis methodological analyses where by the drainage channels and its confluences makes relative maps to the different base levels represented by the isobasis, characterizing itself by an attempt to rebuilt the preterit local landscape. There were elaborated eight maps referring to four orders of confluences met in the region of Cardoso Island and round it where you can conclude it is about an appropriate methodology to rebuilt preterits environments that specially aim to actions of environmental planning and conservation.

Alterações morfohidrográficas do setor de fundo de vale do rio Piracicaba sob influência do reservatório de Barra Bonita (SP)

O homem modifica o ambiente ao seu redor gerando alterações “nos elementos que se encontram em contato direto com suas atividades, como a cobertura vegetal, as formas do relevo e a rede hidrográfica” (CASSETI, 1994). Assim, destacam-se as áreas submetidas ao represamento, cujos reflexos incidem diretamente sobre as formas do relevo. Desta forma, a geomorfologia atua como uma ciência de análise das alterações ocorridas na rede de drenagem e nas feições geomorfológicas, e a cartografia geomorfológica antecipa-se como instrumento da geomorfologia. O objetivo principal da pesquisa foi identificar e analisar as alterações morfohidrográficas e morfométricas provocadas pela construção do reservatório de Barra Bonita no curso final do Rio Piracicaba. A orientação metodológica vincula-se à Teoria Geral dos Sistemas Aplicada à Geografia e à análise da dinâmica de sistemas morfohidrográficos. Para as técnicas, foram confeccionados mapas geomorfológicos e de uso e ocupação das terras dos anos de 1962 (ano anterior à construção da barragem) e 2007 (selecionado como ponto de partida para a análise das alterações morfohidrográficas). Em 1962 existiam barras de meandro, canais e meandros abandonados, terraços fluviais, diques marginais, lagos e lagos de meandros. Em 2007 estes são comprometidos devido à mudança de nível de base local, fato demonstrado pelo desaparecimento de meandros e canais abandonados nas planícies aluviais, fragmentação de terraços fluviais, mudança de foz pelos canais tributários do rio principal e surgimento de novas lagoas. Para o uso, no ano de 1962 existiam grandes áreas de vegetação de “campo úmido”, atrelado à feição geomorfológica “planície aluvial”, que se encontrou alagada no ano de 2007. Foram também calculados os índices de sinuosidade, densidade de meandramento, número de meandros, área... (Resumo completo, clicar acesso eletrônico abaixo)

Analyses were based on communication theories covering concepts such as the Excellence in Public Relations, the questioning about the definition of public flashing and discussion about the processes of interaction mediated by the Internet. The evaluation of the channels covered the period of 30 days and that the end of the checks it was found that most brands promote specific actions with surface interconnections between media channels, referring only to the effectiveness of social networks like Twitter, Facebook and Orkut in order to consolidate of relationships

Diagnóstico antropogeomorfológico em bacia hidrográfica urbana: o caso do Córrego do Jardim São João, Araras (SP)

Man can transform the nature according to their needs through technique which enables agriculture, cattle raising, constructions of buildings for housing, transport routes, etc. This action has brought significant transformations to the environment, and relief is one of the most changed elements, mainly at urban areas, which concentrates most of the Brazilian population. In these areas geomorphologic systems have undergone alterations in their flow of matter and energy by the action of man. Thus, it is possible o understand the action of man as geomorphologic action, nowadays, the tecnógeno, since the human action can interfere qualitatively and quantitatively in the input and output of these systems. The anthropic geomorphology has contributed to the analyses of the effects due to the urbanization at the form and at the geomorphologic process in the urban watersheds, indicating the transformations at the shape of the relief and the alterations due to the acceleration of the flow of matter and energy. From these questions, this study had the main diagnose the anthropogenic changes of the relief at the basin of Corrego do Jardim São João, Araras (SP), comparing two scenes, 1997 and 2006, through geomorphological mapping evolutionary in the area. The geomorphological feature altered at the basin are directly linked to the use of soil, mainly at the urban use, which caused effects in the relief at the studied area, making possible to define periods of the urban evolution and impacts caused by the urbanization. Among the changes it was found the decrease of the topographic breaks and at the riverbed channels, as the increase of the accumulation of the plain and riverbed terrace. The elaboration of a letter of the legal restrictions of the basin make possible to evaluate some of the environmental urban problems that occur, which are due to the occupation of the relief in the areas of permanent preservation that brings significant impacts to...

Influência do uso de hipoclorito de sódio 2,5% e extrato glicólico de sálvia 20% durante o preparo biomecânico sobre a resistência adesiva de retentores intra- radiculares: avaliação através do teste de push-out

The aim of this study it was to evaluate the use of irrigating solution used during root canal preparation on the adhesive cementation of prefabricated fiberglass pins. The bond strength between different regions of the root and the fiberglass pins cemented into the root canal were evaluated by push-out assay. For this study, 36 human teeth were used, all equally prepared. The irrigating solutions used for biomechanical preparation were: saline solution, sodium hypochlorite 2,5% and glycolic extract of salvia 20%. The dual cure resin cement was used for cementation of pins. After cementation, specimens were sectioned to give 3 slices of approximately 2 mm each (cervical, middle and apical), which were submitted to mechanical push-out test. Were performed ANOVA and Tukey's test with a significance level of 5%, for the analysis of mechanical test. Comparing the thirds we observed that the only solution that presented statistical difference in the bond strength was sodium hypochlorite, which showed higher values for the middle and apical third compared with the cervical third, but when compared without taking into consideration the dental thirds, solutions studied showed no differences in bond strength. Therefore, it was concluded that the solutions studied can be used during endodontic treatment without causing harmful effects on the final adhesive restoration

O município de Franca-SP situa-se na Província Geomorfológica das Cuestas Basálticas no nordeste paulista, a qual possui características ambientais próprias. De uma forma geral, a região de Franca enfrenta problemas ambientais como a suscetibilidade à erosão linear e laminar, aos movimentos de massa e ao assoreamento dos canais de drenagem. Estes problemas, por sua vez, induzem a situações socioeconômicas, como o incremento da pobreza, aglomeração urbana e, uma emergente demanda da sociedade por mudanças no âmbito da gestão local. Assim, devem ser efetuados estudos detalhados sobre o meio, a fim de minimizar e/ou evitar tais problemas. Desta forma, propos-se a realização do Zoneamento Geoambiental, o que implica no levantamento, análise, interpretação e correlação dos diferentes componentes ambientais, visando dar subsídio a órgãos públicos e proprietários rurais, tanto na fase de planejamento como na implantação de culturas agrícolas, pecuária, reflorestamento e uso da água superficial (lençol freático), de maneira racional e ambientalmente sustentável, garantindo assim a ocupação adequada do solo e a melhor conservação dos recursos naturais. O trabalho iniciou-se com a organização e reinterpretação dos dados pré-existentes (topográficos, geológicos, pedológicos, geomorfológicos, morfoestruturais, de coberturas de alteração intempérica e sócio-econômicos) e geração e/ou reorganização de novos dados e propostas para a minimização dos impactos sócio-ambientais (rede de drenagem, hipsométricos, morfométricos, tectônicos, geológicos, geomorfológicos, climáticos e bióticos) com a utilização de técnicas de fotointerpretação de diversos sensores remotos e de campo.

Tomografia por Biosusceptometria de Corrente Alternada (tBAC): desenvolvimento, caracterização, implementação

The Biosusceptometry AC (BAC) is a research tool that has been extensively explored by the group Biomagnetism IBB-UNESP for monitoring of the gastrointestinal tract, its response to a known drug or in vivo performance of solid dosage forms. During this period the BAC, which has the characteristics of high sensitivity and low cost, has been developed primarily for recording signals contraction of activity and traffic human gastrointestinal tract. With the possibility of producing images with this instrumentation, it was possible to evaluate different situations in vitro and in vivo for physiological studies and pharmaceuticals. Considering the good performance of this system to produce planar images, the first aim of the BAC system tomography (TBAC) was to evaluate the system performance of BAC to produce tomographic images of phantoms ferromagnetic for a single channel system. All these applications were only possible because of their sensitivity to materials of high magnetic suscepitibility as ferrite, which allow to produce an electrical signal proportional to the variation of the magnetic flux generated by the presence of magnetic marker next to a first-order gradiometer. Measuring this variation at various points was possible to generate planar images that recently came to be produced in systems with multiple detectors, said multi-channels. From planar images, also producing tomographic images of simulators BAC bars in a system of 13 channels using only the center channel, with good results when applied to simple objects as one and two bars. When testing the resolution of the system with more elaborate forms the quality and resolution of images reconstructed is not satisfactory, which would be solved by increasing the spatial sampling rate and hence the acquisition time. The present system works with an acquisition time of about five hours. Whereas this system will be applied for in vivo experiments, the acquisition time became a ...

Estudo teórico da contribuição a dose de partículas secundárias geradas por prótons de energias entre 100-200 MeV num phantom de músculo estriado

In the treatment plans in conventional Proton therapy are considered only the elastic interactions of protons with electrons and/or nuclei, it means, mainly ionization and coulomb excitation processes. As the energy needed to reach the deep tumors should be of several hundred of MeVs, certainly the nuclear inelastic channels are open. Only some previous studies of the contribution of these processes in the full dose have been made towards targets composed of water. In this study will be presented the results of the simulation of the processes of interaction of beams of protons in the range of 100-200 MeV of energy with a cylindrical phantom composed by striated muscle (ICRU), emphasizing in the contribution to total dose due to the deposition of energy by secondary particles alpha (α), deuterium (2H), tritium (3H), neutron (n) and hélio3 (3He), originated by nuclear inelastic processes. The simulations were performed by using the method of Monte Carlo, via the computer code MCNPX v2.50 (Monte Carlo N-Particle eXtended). The results will be shown demonstrated through the graphics of the deposited dose with or without nuclear interaction, the percentual of dose deposited by secondary particles, the radial dispersion of neutrons, as well as the multiplicity of secondary particles
