OBJETIVO: Apresentar uma revisão de literatura sobre o bruxismo na infância, abordando os fatores etiológicos, as características clínicas, os sinais e sintomas, a importância do diagnóstico por parte dos pediatras e odontopediatras e o tratamento multidisciplinar desta condição parafuncional. FONTES DE DADOS: Foram selecionados os artigos mais relevantes sobre o tema publicados desde 1907 até 2007, com pesquisa realizada no Medline, na Bibliografia Brasileira de Odontologia (BBO) e em livros de Odontologia. SÍNTESE DOS DADOS: O bruxismo é definido como um hábito não funcional do sistema mastigatório, caracterizado pelo ato de ranger ou apertar os dentes, podendo ocorrer durante o dia e durante o sono. A etiologia é multifatorial e a literatura sugere vários fatores associados: dentário, fisiológico, psicológico e neurológico. As forças exercidas pelo bruxismo podem provocar distúrbios em diferentes graus nos dentes e nos tecidos de suporte, na musculatura e na articulação têmporo-mandibular. O sinal mais comum é o desgaste nas faces incisais dos dentes anteriores e oclusais nos posteriores, além de mobilidade e hipersensibilidade dentárias, fratura de cúspides e restaurações e hipertonicidade dos músculos mastigatórios. CONCLUSÃO: O conhecimento dos fatores etiológicos e das características clínicas do bruxismo na infância é fundamental para que o diagnóstico seja precoce, permitindo que pediatras, odontopediatras e psicólogos possam estabelecer um tratamento multidisciplinar e favoreçam o desenvolvimento integral da criança para a promoção de saúde e bem-estar individual.

A review of recent literature shows that most taphonomic studies of Holocene and fossil macrovertebrates are not methodologically standardized. Hence, results from distinct studies are not comparable, even among researches sharing virtually identical goals, targeting the same biological group of similar age and depositional environment. The effects of the shell size in the taphonomic analysis are still poorly understood. In order to study this issue, the taphonomic signatures (articulation, valve type, fragmentation, abrasion, corrosion, edge modification, color alteration, bioerosion and encrustation) of brachiopod shells (Bouchardia rosea (Mawe)), from Ubatuba Bay in the northern coast of São Paulo State, were investigated according to the sieve sizes. In the study area, 14 collecting stations were sampled via Van Veen grab sampler, along a bathymetric gradient, ranging from 0 to 35 m of depth. Bulk samples were sieved through 8 mm, 6 mm, and 2 mm mesh sizes, yielding a total of 5.204 shells. The results indicate that, when taphonomic signatures were independently analyzed per size classes (8 mm, 6 mm, and 2 mm), the taphonomic signatures are recorded in a complex and random way. Additionally, cluster analysis showed that the similarity among the clusters vary according to the considered sieve size. Thus, the sieve size plays an important role in the distribution of taphonomic signatures in shells of distinct sizes. These results suggest that the concentration of the taphonomic analysis on one class (e.g., the largest sieve size, 8 mm) is not always the best method. Rather, the total data (all sieves included) seems more accurate in recording the whole spectrum of taphonomic processes recorded in shells of a given assemblage.

The history of concepts, albeit still little explored by information science, can provide important contributions for the study of key concepts that constitute the theoretical-conceptual framework in a scientifi c context. Thus, the history of concepts is presented as a tool for the study of diachronic and synchronic features of the scientific concept in Information Science. For such, it was imperative to understand the intersection of the categorical-abstract and analytical-causal dimensions, both relevant for constituting the very proposition of the history of concepts elaborated by Reinhart Koselleck.

Municipal Plans of Risk Reducing (PMRR's) were produced in settlements in the municipalities of Itapecerica da Serra (SP) and Suzano (SP), covering areas at risk of landslides and washouts of banks of streams. The development of PMRR's provided the delimitation of areas of risk, the indication of intervention works in order to eliminate and / or reduce risks, and consequently an indication of the areas and priority sectors for implementation of intervention works. The prioritization of areas and sectors that should receive the works of reducing or eliminating risk was performed by an expert involved in risk mapping. Despite the specialist's judgment exercise caution, the decision regarding the priority sites for implementation of alternative interventions is subjective. Since there is no way to eliminate this subjectivity, the use of decision-making techniques is important to evaluate whether the expert's reasoning is consistent. One of the first techniques developed for multiple criteria is the AHP (Analytic Hierarchy Process). This paper describes the results of a research carried out in order to assess whether the use of Analytic Hierarchy Process contributes to the results of the indication of the areas and priority sectors for implementation of interventions can be considered more consistent than in situations where the priority occurs without the use of decision making techniques. Results were compared between the prioritization of interventions for implementation contained in PMRR's of Itapecerica da Serra and Suzano and those obtained from the use of Analytic Hierarchy Process (AHP). It was concluded that such techniques permits an evaluation of the expert's judgment is logically coherent, thus contributing to produce results more technically based.
