Prevalência e determinantes de oclusopatias nas dentições decídua, mista e permanente na cidade do Natal/RN

This work is intended to bring a contribuition to the verification of the prevalance of malocclusion in the deciduous, permanent and mixed dentition in the student population in the city of Natal, Brazil. In this purpose, a sectional study of infantiles aging 5, 8 and 12 years old was carried out. The average prevalance of malocclusions in the group as a whole was 76,5%. Considering the different dentitions separately, the study showed malocclusion prevalence as follows: Deciduous Dentition 75,5%; Mixed Dentition 84% and Permanent Dentition 70,5%. The most common malocclusion cases found in the deciduous dentition were openbite (20.6%); overbite (16.6%) and maxillary overjet (14,7). Mixed Dentition: the most commonly found occlusional malfunctions in this dentitional phase were maxillary overjet (33,8%); crowding (28,3%), and mandillary discrepancy (19,9%). In the univaried analysis, he application of the Chi square test of independence, (significance 5%), has indicated a meaningful association of the variables social class (p=0,019), primata space (p = 0,036), habits (p= 0,002) and time-and-habit (P=0,03). The same test on the permanent dentition group revealed a significant association for the independent variables, as follows: Social class (p=O,OOO), School (p=O,OOI), Income (p=O,OOO), housing standard (p=0,001), facial pattem (p=0,004), caries record (p=0,031). No significant association was found in the mixed dentition. The Logistic Regression analysis on the deciduous dentition has shown that income, ethnicity, habit and canine relationship constitute factors of risk regardless of the other variables. As for the permanent dentition, only Facial Pattem was pointed as a factor of risk for the formation of malocclusion

Uso de habitat, orçamento temporal e influência da maré da geomorfologia do fundo sobre o comportamento do boto Sotalia guianensis Van Bénéden, 1864 (Cetacea: Delphinidae) no Porto de Maceió - Alagoas, Brasil

The physical and environmental factors presented by each habitat and the rhythm of behavior patterns strongly influence the ecology and behavior of the all living beings. At same time this factors may provide clues about the structure of a population and its ecological balance. The organizational structure, ecology and behavior of a species appraised in a region if we know be in balance when compared to the same type of appraisal made in a degraded area can provide a clear view of how the anthropogenic influences acted on these species and what steps can be taken in order to mitigate the effects and keep the population. The region where this study was conducted is, like most areas of port, subject to intense physical and environmental degradation. With the emerging interest of change in the quality of these environments also by the companies themselves that use the port services, the proposed study aimed to characterize the use of habitat, the distribution of behavioral activities carried out throughout the day and influence of geomorphology of the bed, depth and variation of tide on the expression of the behavior of Sotalia guianensis in the port of Maceio - Alagoas. From this information will be possible establish parameters for comparison with other populations of S. guianensis and establish conservation measures for the population occurring in the port of Maceio - AL, serving also as a basis for conservation actions future performed in other port regions

Estudo sobre orçamento de atividade do Boto Cinza (Sotalia guianensis) no litoral sul do Rio Grande do Norte

A fundamental analysis on Behavioral Ecology is the construction of Activities Budget, which can be defined as the quantification of the time that each animal uses in activities that are important for its survival and reproduction. Initially developed for theoretical studies about Optimal Foraging, the construction of Activities Budgets has recently being used for analyses in Conservation Biology. However, the measurement of behavior through an adequate methodology that allows the comparison between different samples is a challenge for researchers in the area of Ethology. This problem is even bigger for the students of cetaceans behavior due to the difficulty of visualization of these animals. The present work deals with two aspects of the specialized literature on cetaceans: i) it explores possible variations of results in quantification of behavioral states decurrent of the application of different methods of data collection, and ii) it describes the activity budget of a population of Sotalia guianensis that inhabits coastal waters, south Rio Grande do Norte. The results showed that the use different methods of data collection result in significant differences, but of small scale, in the quantification of the behavioral frequency. The activity budget of Sotalia in the area here analyzed was similar to that described for other populations of this species inhabiting typically estuarine habitats. Tide and day-hour did not influence the dolphin s behavior, however, significant differences were found related to the position of the animals within the area. These results are discussed considering the dietary and behavioral flexibility of the species, contributing to the scientific knowledge and offering information that will be useful in comparative studies and for analyses on the determination of areas for species conservation

Estudo cefalométrico das alturas faciais anterior e posterior, em crianças brasileiras, portadoras de má oclusão Classe I de Angle, na fase de dentadura mista

Realizou-se um estudo das alturas faciais anterior e posterior em 79 crianças brasileiras, sendo 46 do gênero feminino e 33 do masculino, com idades de 8 a 11 anos, portadoras de má oclusão Classe I de Angle, na fase de dentadura mista, não submetidas a tratamento ortodôntico. Esta investigação utilizou duas radiografias cefalométricas em norma lateral, de cada criança, com intervalo de 8 a 16 meses entre uma radiografia e outra, para comparação dos dados cefalométricos. Foram estudadas as proporções faciais anteriores, ou seja, a relação entre as dimensões N-Me (AFT), N-ENA (AFS), ENA-Me (AFI) e o relacionamento entre as dimensões Ar-GO (AFP) e a distância entre o plano palatino ao mento (AFA) , isto é, o Índice da Altura Facial (IAF). Os resultados obtidos, possibilitaram constatar que as tendências de crescimento foram equilibradas em todas as situações estudadas; a dimensão altura facial inferior, contribuiu de forma mais significativa, nas alterações observadas na altura facial total; as proporções faciais anteriores se mantiveram em torno de 42% para a altura facial superior e 58% para a altura facial inferior; o índice da altura facial ou se manteve constante em torno de 0,66 ou apresentou uma tendência a aumentar com a idade; não ocorreu dimorfismo sexual com relação às proporções faciais e índice da altura facial.

Efeitos dentoesqueléticos produzidos pelo aparelho de Herbst na dentadura mista

OBJETIVO: o objetivo desta pesquisa clínica prospectiva foi avaliar as alterações cefalométricas dentárias e esqueléticas produzidas pelo aparelho de Herbst em jovens com má oclusão de Classe II, 1ª divisão durante a dentadura mista. METODOLOGIA: trinta jovens (15 do gênero masculino e 15 do feminino) com idade média inicial de 9 anos e 10 meses foram tratados com o aparelho de Herbst por um período de 12 meses. Para a comparação dos grupos utilizou-se uma amostra controle de 30 jovens (15 do gênero masculino e 15 do feminino) Classe II, 1ª divisão, com idade média inicial de 9 anos e 8 meses, que foram mantidos sem tratamento durante 12 meses. Para cada jovem foram utilizadas duas telerradiografias em norma lateral, obtidas ao início e no final do período de acompanhamento. Utilizou-se um método convencional de avaliação cefalométrica e o método proposto por Pancherz. RESULTADOS E CONCLUSÕES: os resultados deste estudo demonstraram que os efeitos do aparelho de Herbst produzidos na dentadura mista foram primariamente de natureza dentoalveolar. Os incisivos inferiores foram inclinados para vestibular e os superiores foram retruídos; também houve uma extrusão significante dos molares inferiores, enquanto os superiores sofreram restrição de desenvolvimento no sentido vertical. Não houve diferença significante de restrição do crescimento anterior da maxila entre os dois grupos. No sentido vertical da face, a altura facial ântero-inferior se comportou de forma similar, não demonstrando alteração significante entre os grupos. O tratamento com o aparelho de Herbst produziu um aumento modesto, porém, significante no comprimento da mandíbula comparado ao grupo controle. Este aumento, entretanto, foi de menor magnitude que aquele observado em pacientes adolescentes utilizando o mesmo protocolo de tratamento. A correção do overjet (Herbst) ocorreu devido a 22% de alterações esqueléticas e 78% de alterações dentárias. A correção da relação molar ocorreu devido a 27% de alterações esqueléticas e 73% de alterações dentárias.

Persistência de mamíferos de médio e grande porte em fragmentos de floresta ombrófila mista no estado do Paraná, Brasil

The Araucaria Forest is now represented by remnants of what was a continuous area of about 200,000 km(2). Medium and large mammals inhabiting this forest have suffered the impacts from the disturbance process and environmental degradation. Thus, this study determined which medium and large mammal species still inhabit the remnants of this vegetation type in Western Parana State. Three study areas, with 520, 405 and 135 hectares, consisting of stretches of primary forest mixed with secondary forest, were considered for mammal inventory. The evidence of mammals was verified directly (views) and indirectly (traces, trichology and interviews with local dwellers). It was recorded 32 species (including one exotic and two small ones), belonging to eight orders and 18 families. Nine animals of these species are at risk of extinction in the Parana State and five configure with insufficient data in the List of Endangered Species of the state. The results of this study indicate the great importance of these forest fragments in the conservation of several medium and large mammals in the Araucaria Forest of Parana State. Nevertheless, due to the negative pressures that these areas have been suffering, immediate and concrete public actions are required to ensure the maintenance of these mammal populations.

Aspectos físico-químicos e microbianos do queijo maturado por mofo obtido da coagulação mista com leite de cabra congelado e coalhada congelada

Milk goats are indicated as an economic alternative for small farmers and cheese making could improve their profits. Goat's milk has a seasonal production characteristic and shows periods of abundance and others of scarcity. The use of frozen milk or frozen curd to make cheese can be used to solve the problem. The aim of this work was to evaluate the preparation of cheese made from mixed curd and ripened by Penicillium candidum mould using slow frozen milk (in a domestic freezer) or fast frozen milk (by liquid nitrogen). The slow frozen curd and fast frozen curd without whey were used. It was observed that the cheese from the slow and fast frozen milk and from the slow and fast frozen curd did not differ from the control cheese for the yield, chemicophysical characteristics, chemical composition, extention ripened rate, depth ripened rate and microbiological aspects, even when it was expressed as a dry matter content of cheeses.

Orçamento participativo e gestão democrática no poder local

The end of the authoritarian regime in Brazil resulted in new forms of democratization of politics and its institutions, with the strenghtening of the civil society. The Participatory Budgeting is an important experience of that new way, characterized by the assumption of the new responsibilities by the local governments. The comparative approach of those experiences, conducted from different party coalitions - in Piracicaba (1989-1992) and in Santa Bárbara d'Oeste (1997-2000) -, allows a test of their powers and limits from a procedural conception of democracy and the complementary role of the participation. In contrast to a view that gives priority to representation, the analysis discusses the range of the new civil society actions from the perspective of the democratization process in the scope of the Local Government. © 2007 CEDEC.
