A concepção de cultura em Vigotski: contribuições para a educação escolar

Este trabalho analisa a concepção de cultura em Vigotski, procurando responder qual a ideia de cultura presente na obra desse autor para, a partir dela, destacar a importância do ensino escolar no desenvolvimento dos indivíduos. A influência da cultura sobre o desenvolvimento psicológico era estudada por esse autor a partir da análise do processo de emprego de signos como meios auxiliares das funções psíquicas, transformando-as de funções espontâneas em funções voluntárias. As funções psíquicas mediadas pelo uso dos signos existentes na cultura eram consideradas como funções superiores por Vigotski, sendo assim, imprescindíveis para o desenvolvimento do homem. A cultura para este autor é produto das leis históricas determinadas pelas condições concretas da existência humana e, assim sendo, o homem nessa perspectiva produz cultura, mas também é fruto das relações sociais, que são internalizadas por ele e que se expressam na forma de funções psíquicas.

Intrusão de incisivos superiores com periodonto comprometido

O tratamento ortodôntico de pacientes periodontalmente comprometidos requer abordagem interdisciplinar que envolva diferentes especialidades odontológicas para que sejam obtidos resultados estéticos e funcionais satisfatórios. Normalmente, pacientes adultos com problemas periodontais apresentam migração dentária, erupção patológica e diastemas. Essas alterações de posição, geralmente, são o resultado da falta de equilíbrio entre o suporte periodontal e as forças oclusais que estão atuando nos dentes durante a mastigação e movimentos funcionais.

Manejo das fraturas nasais com manutenção das vias aéreas superiores

Nasal fractures are extremely frequent. The nasal bones are the third most frequently fractured bones in the human skeleton. This is due to their prominent position on the face and to the diminished bone thickness. As a result, weak forces can cause nasal fractures, while stronger forces can comminute the nasal bones. In general, assaults, falls and sports injuries are the etiologies most commonly involved in nasal trauma. The diagnosis of such fractures is basically clinical and their treatment is usually by closed reduction with good results reported in all the relevant literature. Thus, the aim of this paper is to report a modification of the closed reduction technique for the treatment of these fractures.

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.

Métodos de avaliação de risco de desordens músculo-esqueléticas nos membros superiores voltados para a odontologia

The dental professionals are exposed to many risks of development of occupational diseases and the musculoskeletal disorders in the upper limbs are the most common disease. This problem may result in lower productivity and / or early retirement. Therefore, early diagnosis should be done through a reliable and valid system of risk assessment. Because of that, this study set out to conduct a review of the literature on methods of risk assessment of musculoskeletal disorders in the upper limbs in dental professionals. Conclusion: It was concluded that the available methods for assessing the risk of musculoskeletal disorders in dentistry are self-reports, observational and direct. Among these methods, the self-reports were frequently used to detect the risk of musculoskeletal disorders among dentists, dental students and professionals from the dental team. Further studies should be performed in dentistry using observational and direct methods.

Análise dos troncos radiculares, abertura da raízes e projeções cervicais de esmalte de furcas de molares superiores e inferiores: Estudo in vitro

Periodontal treatment of teeth with furcation lesions often have unpredictable results due to several factors that may hinder therapy or influence the progress of periodontal disease. Of these, the length of the root trunk may contribute to the early injury of the furcations or even cause complications for the application of the treatment; the opening of the roots can guide the type of treatment to be instituted and cervical enamel projections may hinder the instrumentation of the region or even act as a retention plate niche. Thus, the purpose of this study was measured using a digital caliper, root logs database 400 molar both the 1st and the 2nd and both upper and lower as well as analyze using appropriate index type projection cervical enamel and through appropriate classification the opening of the roots in order to guide the diagnosis and treatment plan. We conclude that there is variation in measures of root trunk between the faces of the teeth examined and that greater cervical enamel projection (ECP) correlates with a decrease in the length of the root trunk in the sample evaluated as the first molars have higher occurrence of roots with a degree of opening larger than the second molars.

Modelagem das trajetórias médias do peso vivo e do rendimento de carcaça de tilápias do Nilo (Oreochromis niloticus) por meio de funções B-spline

Employing the method of least squares and quadratic B-spline polynomials, different statistical models were tested to identify the most appropriate to model the mean trajectories of live weight and carcass yield of Nile tilapia (Oreochromis niloticus). Data of live weight (8,758) and carcass yield (2,042) of tilapias with ages between 106 and 245 days were obtained from 72 families derived from 36 males and 72 females. The sex and tank variables were considered as classificatory and the coefficients of quadratic polynomials B-spline of two to five intervals of the same size were used as covariables. According to most fit criteria used, the models with quadratic B-spline polynomial with five intervals of the same size presented the best adjustments. The increase in number of intervals of B-spline polynomial improved the fit of the polynomials to the data. The inclusion of classificatory effects from sex, tank, the interaction of these effects and the quadratic polynomial B-spline nested in this interaction indicated that, over time, each sex, grown in different tank, presented different mean trajectory, necessitating the inclusion of nesting time in the interaction sex x tank in order to avoid the under or overestimation of breeding values of the selection candidates in breeding programs of this species.
