Acupuntura em disfunção temporomandibular: relato de caso clínico

A técnica milenar da Acupuntura vem sendo empregada na Odontologia e obtendo bons resultados em diversas situações. Analgesia, relaxamento muscular e inflamação vêm sendo controlados, demonstrando assim conexão entre Acupuntura e redução de certas sintomatologias. As reações locais e à distância necessitam de correto posicionamento das agulhas assim como integridade do sistema nervoso, e são decorrentes da liberação de neurotransmissores (noradrenalina, acetilcolina, serotoninas e dopamina). Dentro da Odontologia, podemos nos utilizar dos seus efeitos no pré e pós operatório, em xerostomia, cefaléias, trismos, disfunção de ATM por estresse, parestesias, paresias, ansiedade, entre outras condições. Nos casos de disfunção de Articulação Temporomandibular por hiperatividade muscular, podemos utilizar a Acupuntura ao invés de relaxante muscular e antiinflamatório. Nesse trabalho, apresentaremos um caso clínico (paciente MCH, 23 anos, gênero feminino), a qual apresentava crises de dor de cabeça (região temporal), fazendo uso constante de medicação analgésica e antiinflamatória, o diagnóstico estabelecido foi Dor Muscular Local associado à hiperatividade muscular. Através do uso da Acupuntura, após aplicações semanais por 3 meses, houve remissão da dor por completo.

Influence of morphological variables in photoelastic models with implants submitted to axial loading

Purpose: This study used 12 photoelastics models with different height and thickness to evaluate if the axial loading of 100N on implants changes the morphology of the photoelastic reflection. Methods: For the photoelastic analysis, the models were placed in a reflection polariscope for observation of the isochromatic fringes patterns. The formation of these fringes resulted from an axial load of 100N applied to the midpoint of the healing abutment attached to the implant with 10.0mm x 3.75mm (Conexão, Sistemas de Próteses, Brazil). The tension in each photoelastic model was monitored, photographed and observed using the software Phothoshop 7.0. For qualitative analysis, the area under the implant apex was measured including the green band of the second order fringe of each model using the software Image Tool. After comparison of the areas, the performance generated by each specimen was defined regarding the axial loading. Results: There were alterations in area with different height and thickness of the photoelastic models. It was observed that the group III (30mm in height) presented the smallest area. Conclusion: There was variation in the size of the areas analyzed for different height and thickness of the models and the morphology of the replica may directly influence the result in researches with photoelastic models.

Influência do aumento do comprimento de implantes dentários

The use of implants of greater length may be more favorable for the predictability of dental implants. This statement is relevant, since the cause of failures in dental implants are more related to biomechanical complications. The aim of this study was to evaluate the influence of increase of the length around the entire body of the implant. Six models were created with the presence of only one hexagonal implant (Master Screw connection, Implant Systems, São Paulo, Brazil) of 3.75 mm x 7.0 mm (Model A), 3.75 mm x 8.5 mm (Model B ), 3.75 mm x 10.0 mm (Model C) 3.75 mm x 11.5 mm (Model D) 3.75 mm x 13.0 mm (Model E) 3.75 mm x 15.0 mm (Model F) using the method of photoelasticity. The results were visualized through a qualitative analysis of stresses (number and intensity photoelastic fringes). The model A showed a pattern of less favorable stress distribution, the oblique loading was the most detrimental to the related structures. Conclusion: The increased length allowed for a better distribution of stresses. The oblique loading was more detrimental when compared to axial loading.

Influência da angulação do implante e tipo de intermediário na distribuição das tensões

The aim of this study was to evaluate the influence of implant angulation and abutment type (UCLA and Estheticone) on stress distribution in screw-retained implant-supported prostheses through photoelasticity. Three models were fabricated with photoelastic resin PL-2 (Vishay, Micro-Measurements Group, Inc Raleigh, N.C., USA) containing one external hexagon implant with 3.75x10mm (Master screw, Conexão Sistemas de Prótese Ltda., Arujá, São Paulo) with 0°, 17° and 30° degrees and a screw-retained prostheses with UCLA and Estheticone abutments. The assembly was positioned in a circular polariscope; axial and oblique (45° degrees) loads of 100N were applied in fixed points on the occlusal crown surfaces by a universal testing machine. The stress generated was photographed and analyzed qualitatively with appropriate software (Adobe Photoshop®). The results demonstrated the same number of fringes for both abutment types for each angulation, with fringes increasing in the same way. A higher number of fringes were closer in the oblique loading mode. It was concluded that there was no significant difference in stress distribution in prostheses with UCLA and Estheticone abutments. Higher stress concentrations were observed with increased implant angulation. Stress concentration and intensity were higher in the oblique load than in axial load application.

Núcleo mídia press: um núcleo de pesquisa na internet

The researching centre mentioned was conceived em 1989, with the goal to study and implement the media of comunication by creating and effecting online printed medias for care institutions, schools and UNESP. The university has taken a give-and-take function between itself and the society. The founder of this group is Prof. Dr. Ricardo Nicola that since 1996 has established a link between university and society, using this centre for developing works that go over the university's borders. The group's work comprehends four different classes: literary , tecnical, journalism and advanced research . The literary one involves help and literary production for new authors, the tecnical helps in publishing theses; the journalism one is related to journal and medias in and out of the university; the advanced research one has is caracterized as a class between departments and branches.

Uma sinapse científica: a neurociência encontra a psicologia

The aim of this paper is to present aspects of the prominent findings of neuroscience in relation to psychological phenomena long studied in psychology. One of the basic points of this presentation is to show briefly the relationship between the anatomical and physiological structures linked to certain human behavior resulting from the evolution of species and the socio-emotional development of the individual.

Comunicação pública e relações públicas: sintonia a favor do cidadão

O presente artigo pretende analisar a Comunicação Pública como uma vertente de comunicação focada na construção da cidadania, demarcando-se na contemporaneidade como uma iniciativa à participação do cidadão nos meios de comunicação. Destacamos, especialmente, o rádio por ser um meio de comunicação de amplo alcance viabilizando espaços de diálogo com o ouvinte, fomentando a reflexão a respeito de conflitos e divergências públicas, ou seja, como um agente gerador de cidadania. Nessa perspectiva faz-se uma conexão entre as teorias de Comunicação Pública em complemento ás teorias e habilidades de Relações Públicas, enfocando a atuação deste profissional comprometido com as questões sociais e como propulsor da cidadania.

Redes sociais na Internet: uma investigação sobre práticas de compartilhamento de arquivos no Facebook

The social networking sites have experienced a large and rapid growth in recent years and bring together millions of users in Brazil and worldwide. Such networks allow adding groups of people with common interests or relationships, enabling members of this group to communicate and exchange information. Some social networks have specific goals, for example, aggregate individuals with common interests and professional relationships. However, they all share information in some way, whether in the form of short texts, photos, videos, among others. Sharing information in files is also a growing activity on the Internet and can be done in various ways, from sending files via email to multiple contacts to make available areas shared by the same contacts. However, applications are not yet available to enable file sharing on Facebook, considered the premier social network today. Given the growing demand for sharing files over the Internet, and a large number of users familiar with the use of these integrated applications for Facebook there is a demand for applications that allow users to share files with their contacts in this social network. This study aims to investigate how users use Facebook, and their practices for file sharing. It is believed that the results will substantiate future projects to develop software for file sharing on Facebook. Due to the exploratory nature of this research, the choice was made for a survey to collect data, applied through the web. From the results obtained, was possible to observe a frequent use of file sharing, but no interest in paid services. Regarding Facebook, was possible to observe their extensive use in both the frequency of access as the hours spent, as well as an increased use of applications (games, quiz, etc.). The full set of results shows a favorable environment for developing applications for sharing files on Facebook.

Com que conteúdo eu vou ao currículo que você me convidou? Geografia e história no ensino fundamental

This paper intends to reflect on the search, in the process of teaching formation, of pre-defined contents for the teaching of Geography and History in the series of primary school. This desire for clarity about the appropriated contents for the various series often overshadows the real need to clarify what is the goal of teaching this or that content. It is necessary, in the teacher training, resume and historically contextualize this search for curriculum contents. The risk of prioritizing the discussion about contents is transforming the contents itself into the content goals of education. Reifying the contents contributes to the common process of disconnect teaching from learning. In this case, the educational process becomes a contest of teaching contents, not bothering if these contents were or not learned by the students, which makes education extremely conservative. This phenomenon has it origins in the 1970s, during the curriculum discussions of the various areas of school knowledge. Since then, the concept of didactic transposition has been questioned progressively, in which the curricula were designed as adapted teaching to lower levels of scientific knowledge produced in universities – the place for higher education. The school knowledge, since the 1970s, is considered as autonomous. In other words, knowledge in dialogue with university science, but with typical characteristics of education in school systems. If the curriculum of primary and secondary educations is not the result of the didactic transposition, what content it should be made of? The current paper touches this issue, but subordinates it to most relevant questions about the purposes of learning in inseparable connection with teaching.
