Avaliação ortopantomográfica das angulações mesiodistais de caninos, pré-molares e molares inferiores com e sem a presença dos terceiros molares

OBJETIVOS: comparar os valores médios normais das angulações mesiodistais dentárias, propostos por Ursi, em 1989, com as angulações mesiodistais de caninos, pré-molares e molares inferiores em indivíduos com e sem a presença dos terceiros molares inferiores e idades entre 18 e 25 anos. Além disso, foram comparados os valores das angulações mesiodistais desses dentes nessas duas situações. MÉTODOS: foram utilizadas 40 radiografias ortopantomográficas de indivíduos, de ambos os gêneros, que não receberam tratamento ortodôntico, divididos em dois grupos: Grupo I, constituído por 20 radiografias que não apresentavam os terceiros molares inferiores; e Grupo II, formado por 20 radiografias com os terceiros molares inferiores presentes. RESULTADOS E CONCLUSÕES: a análise dos resultados e a análise estatística permitiram concluir que ambos os grupos exibiram pré-molares e molares inferiores mais angulados em sentido mesial, quando comparados à oclusão normal. Por outro lado, a angulação mesiodistal de caninos inferiores mostrou-se semelhante àquela apresentada em casos de oclusão normal. Os dois grupos, quando comparados entre si, exibiram semelhantes valores angulares dos caninos, pré-molares e molares inferiores, de modo que a presença dos terceiros molares não exerceu influência sobre essas angulações mesiodistais dentárias.

Prevalência de periodontite agressiva em adolescentes e adultos jovens do Vale do Paraíba

O objetivo do presente estudo foi avaliar a prevalência de periodontite agressiva localizada, periodontite agressiva generalizada e periodontite incipiente em uma população de 15 a 25 anos de idade (19,4 ± 3,44) da região do Vale do Paraíba - SP que procuraram tratamento odontológico clínico geral no Departamento de Odontologia da Universidade de Taubaté, SP. Seiscentos pacientes, 244 do sexo masculino e 356 do sexo feminino, foram incluídos neste estudo. A condição periodontal da população estudada foi determinada em 6 sítios por dente por meio da avaliação das medidas de profundidade à sondagem e nível clínico de inserção, e confirmada por meio de exame radiográfico. Dez indivíduos (1,66%) apresentaram periodontite agressiva localizada, 2 do sexo masculino (18,5 ± 2,12) e 8 do sexo feminino (19,2 ± 3,91), 22 (3,66%) receberam diagnóstico de periodontite agressiva generalizada, sendo 6 do sexo masculino (19,1 ± 3,06) e 16 do sexo feminino (20,1 ± 2,71) e 86 (14,3%) foram diagnosticados com periodontite incipiente, 29 do sexo masculino (20,2 ± 2,87) e 57 do sexo feminino (21,1 ± 2,79). Houve correlação positiva entre sexo feminino e doença periodontal.

Estudo antropométrico e dietético de nadadores competitivos de áreas metropolitanas da região sudeste do Brasil

Com o objetivo de caracterizar os ábitos alimentares de nadadores competitivos de dois clubes das cidades do Rio de Janeiro e de São Paulo, foram estudados atletas, 30 homens e 37 mulheres pertencentes às equipes juvenil (15-17 anos) e seniors (18-25 anos). Concomitantemente à avaliação antropométrica, foi feito o inquérito alimentar mediante os métodos de registro alimentar, recordatório de 24 horas e freqüência de consumo alimentar. Os resultados mostraram semelhança antropométrica entre as duas faixas etárias para cada um dos sexos, semelhança dos alimentos prevalentemente ingeridos com aqueles referidos pela população da área metropolitana das duas cidades e semelhança entre os suplementos alimentares ingeridos pelos atletas dos dois clubes. A ingestão calórica observada foi quase o dobro da referida para a população daquelas localidades, mas equivalente à descrita para nadadores de outros países. Os lanches, entre refeições, contribuíram com 25-28% da ingestão calórica global e a maior contribuição energética alimentar foi dada pelo grupo de cereais. Apesar de contribuir com quase 50% do aporte calórico diário, a ingestão glicídica foi menor que a recomendada para atletas competitivos (55-60%). A ingestão protéica de 2,5-3,0 g/kg/dia superou em 100% o valor recomendado para atletas e ultrapassou os 15% na participação calórica diária. A ingestão lipídica foi considerada elevada, particularmente a de gordura saturada. O aporte de micronutrientes foi acima do referido para as populações locais em função da ingestão calórica elevada, mas mostrou-se relativamente inadequado em magnésio, ferro e vitaminas A e D. Conclui-se que o padrão alimentar dos nadadores estudados não difere, muito, do da população local, distinguindo-se pelo elevado e freqüente consumo de alimentos energéticos, maior no sexo masculino que no feminino.

Staphylococcus spp. Na cavidade bucal e na bolsa periodontal de indivíduos com periodontite crônica: presença e sensibilidade aos antibióticos

Staphylococcus are not usually studied in the oral cavity, when this happens, they are considered to belong to transitory microflora. Individuals that present periodontal disease represent possibles reservoirs of these opportunist bacteria in the oral cavity. The use of antibiotics whether for treatment of periodontal disease or due to hospital infections, may predispose the increase of the Staphylococcus spp. in the oral cavity because they easily become resistant to antibiotics, resulting in superinfection. The study was made with 88 patients, minimum age- 25 years old, presenting chronical periodontitis, with, at least, two sites having a probing pocket bigger or equal to 5mm. After anamnese and clinical periodontal examination samples were taken from the periodontal pocket using paper cones and from the oral cavity using mouth rinse. Of the total patients 37,50% presented Staphylococcus spp. in the periodontal pocket and 61,36% in lhe oral cavity; 27,27% presented bacteria in the two sites, not necessarily of the same specie. S. epidermidis was the most prevailing specie in periodontal pocket (15,9%) and oral cavity (27,27%). Positive for S. aureus in the periodontal pocket were 4,5% and for the oral cavity 25%, and 3,4% were positive for the two sites. There was not found significative statistical difference referring to the presence of the microorganisms as to age, smoking habit and increase of the probing depth. The majority of the isolated Staphylococcus samples showed resistance to the tested antibiotics, indicating that the drugs as an adjunct to periodontal therapy, must be seen with caution

Estudo da prevalência de disfunção craniomandibular segundo o índice de Helkimo tendo como variáveis: sexo, faixa etária e indivíduos tratados ou não ortodonticamente

One hundred non-patient dentistry students aged 17 to 25, were interviewed through questionnaire and were clinically examined in order to asses the prevalence and degree of severtty of Craniomandibular Dysfunction, through indeces which are subdivided into three classes: anaminestic index, clinical dysfunction index, and occlusal index. The following variables were introduced to the original indeces: sex, age, and whether the subjects had or had not received orthodontic treatment. The results showed that 42% of the subjects presented mild subjective symptoms whereas, no one showed severe subjective symptoms. Women, as well as the older subjects, showed a higher trend to presenting more subjective complaints. Subjects, whether treated orthodontically or not, showed a similar trend to having dysfunction symptoms. Fifty-six per cent of the subjects presented some score of clinical dysfunction, 25% of them showed moderate or severe clinical dysfunction. Women showed a statistically significant higher index. The older subjects trented to have indeces with more severe degrees. Orthodontic treatment suggested to have no influence on the clinical dysfunction index. Sixty-six per cent of the subjects showed a mild occlusal index and 11% a severe occlusal index. Sex, age, and orthodontic treatment did not show any significant difference as to the presence or absence of malocclusion

Avaiação da Dor e da Postura em Pacientes com Lombalgia Submetidos a Dois Protocolos de Fortalecimento Abdominal

Introduction: the lumbar spine is the main part of the body responsible for the support of the loads, where approximately half of body weight is in stable balance. This support relates to the action of abdominal muscles, of great importance in the balance of that region. The existence of abdominal muscle weakness, such won’t perform its function, may induce pathological postural attitude, that predispose the pain. Objective: to compare the effects of two abdominal strengthening protocols on pain and postural alignment in individuals with low back pain. Method: participated of the study 21 individuals of both genders, with ages between 19 and 25 years old (average 21,8±1,5) and average Body Mass Index (BMI) 21,9 (±2,48), divided randomly in isometric abdominal stimulation group (n=8), abdominal strengthening group (n=7) and control group (n=6). They realized eight sessions of strengthening, when responded Visual Analogue Scale (VAS) before and after each intervention. The control group (n=6) had no intervention. The postural data had been analyzed by photogrammetry. Results: Pain and posture data were analyzed using paired t test, with signifi cance index of 5%. Postural angles had no signifi cant differences (p>0,05) from all angles analyzed after the intervention to none of the groups. For pain values, a signifi cant decrease (p<0,05) was observed since the fi fth session in patients who were treated by the abdominal exercises protocol, and the fi rst session in patients who were treated by the isometric abdominal stimulation protocol. However, this decrease in pain was immediate, not lasting along the treatment sessions, in both protocols. Conclusion: the proposed protocols did not interfere in postural alignment. They were effective to decrease pain in a same session, once the isometric was the most effective, but they weren’t effective in preserving the improves over time.

Avaliação da atenção concentrada e memória em tabagistas com baixa carga tabágica

Introduction: Smoking is considered by World Health Organisation (WHO) a disease, since nicotine is addictive and cause physical, emotional and behavioral disorders in people who smoke. The objective of this study was to evaluate the concentrated attention and memory in smokers and nonsmokers, and the influence of one cigarette in this variables. Material and Methods: We selected two groups of subjects between 18 and 25 years, with no history of acute or chronic respiratory disease. Group 1 (G1) consist of 40 nonsmoking individuals and group 2 (G2) 40 smokers (who smoked less than 20 cigarettes per day, for up to 10 years). The subjects were tested for concentrated attention and memory test (AC Test), nonsmokers performed the test once, smokers performed the test twice, before smoking and after five minutes after smoking one cigarette. Smokers stayed without cigarret for one our before the first test. Results: Comparing the tests nonsmokers versus smokers first test, there was no significant difference (p> 0.05), however, the analysis of the two trials of smokers, showed improvement in concentrated attention and memory after smoke (p <0.0001). Conclusions: There was no difference in Concentrated Attention and Memory among nonsmokers and smokers in abstinence, however smokers showed significant improvement in AC Test after smoking.

Comparação dos parâmetros espaçotemporais da marcha durante a execução do TUG associado à dupla tarefa em adultos jovens

Introduction: Biomechanical analysis of gait can be used effectively to identify changes in movement patterns and functional decline. Objective: To analyze the effect of dual task on gait spatio-temporal variables. Methods: The sample was made up of 32 subjects of both genders aged between 18 and 25 years. The test Timed Up and Go was performed under two conditions: original form and associated with a cognitive task (verbalize backwards the months of the year). We evaluated the total execution time, number of steps, cadence, time spent to lift, average speed and variability of the step time. Results: Significant changes were observed with the addition of the cognitive task in many gait spatio-temporal variables analyzed. Conclusion: The tests showed that the increase of cognitive tasks during walking may lead to changes in the performance of this task.

O retorno: identidades à deriva no romance português contemporâneo

This paper concentrates on the analysis of how the typical voices of History are manifested, which is achieved by the aesthetics of the contemporary Portuguese narrative, as it aims at the same time the reflexion and the reformulation of the Lusitanian cultural imaginary in the course of O retorno, a novel by Dulce Maria Cardoso. The hypothesis that arises is that the trajectory of Rui’s individual experience, as wells as the other’s characters “retornados” looking for identity, is parallel to the proposed revision of the Portuguese nation collective cultural imaginary in the decolonization context, after the 25th April Revolution. It is its objective to investigate how the historical processes concerned to the concepts of exile and uprooting, displacement and belonging (BAUMAN, 2005) are fictionalized in the novel, seen as motes for Rui’s pursuit for identity and for the revision of the Portuguese Destiny theme

Respostas da frequência de braçada e do comprimento de braçada na e acima da intensidade correspondente à máxima fase estável de lactato sanguíneo em indivíduos com diferentes níveis de performance

The main objective of this study was to analyze the behavior of variables related to swim ability at and above maximal lactate steady state (MLSS), performed at continuous and intermittent conditions in individuals with different aerobic performance levels. Participated of this study male swimmers with ages between 20 to 25 years, specialists in events of 400 m, 800 m and 1500 m and open water swims, with at least 3 years of experience in the modality. The individuals performed a maximal 400-m swim test. After this test, they were divided into two groups, in accordance with the speed attained during 400-m swim test: G1 (higher performance) and G2 (lower performance). For the determination of continuous MLSS (MLSSc), 2 to 4 trials of 30-min were performed. For the determination of the intermittent MLSS (MLSSi) 2 to 4 trials of 30-min (12 repetitions of 2 min 30 s, with 30 s of rest) were performed, in constant speed, with the first trial performed at 102.5% MLSSc. Th technical indexes, stroke rate (FB) and stroke length (CB) were determined in all tests. The SR was calculated trough recordings using the time needed to perform five stroke cycles. The SL was calculated dividing the speed by the SR. There was no significant difference on the antropometric characteristics between groups. The speed at and above MLSSc were significantly higher at G1 (1,23±0,05 e 1,27±0,06, respectively) than G2 (1,10±0,06 e 1,13±0,06, respectively). There was significant change in SL and SR in G2. In the same way, there was significant change in SL and SR only in G2, above MLSSc. Similar to continuous condition, the speeds at and above MLSSi were significantly higher in G1 (1,27±0,05 e 1,30±0,05, respectively) do que no G2 (1,14±0,07 e 1,16±0,07, respectively). There was significant change in SL and SR only in G2. There was significant change in SR and SL in both groups above MLSSi. Thus,...(Complete abstract click electronic access below)

Análise das propriedades da madeira de estrutura de telhado após a ocorrência de um incêndio

The present study evaluated the mechanical properties of pieces of wood coming from the roof structure of a residence subject fire in the rural area of Itapeva/SP. The structure was built 25 years ago using wooden beams of the species Guarucaia (Peltophorum vogelianum), where the specimens were removed. The research methodology included qualitative evaluation of the samples, estimating the layer pyrolysis and carbonization of the wood, measuring of density and mechanical tests of compression parallel to grain, tension parallel to grain and shear. The mechanical properties of wood were analytically correlated with the layers carbonization and pyrolysis that are influenced by the temperature and time of fire; these values were estimated at 1000 °C and two hours for the case in question. The results indicate that the strength properties of degraded wood are different from a healthy wood. The level of thermodegradation, in general, can be measured by density, result in weight loss due to decomposition of the wooden components.

Testes funcionais, torque isocinético em inversão e eversão e capacidade de reposicionamento articular: um estudo sobre a estabilidade dinâmica do tornozelo

Introdução: A lesão mais comumente encontrada na população ativa é a entorse de tornozelo. Cerca de 40% destes casos continuam a manifestar sensação de instabilidade articular mesmo após a fase aguda da lesão, caracterizando a instabilidade funcional do tornozelo (IFT). A IFT está relacionada com déficits proprioceptivos e redução na capacidade de produção de força e potência muscular. Haja vista que o basquetebol é um esporte com grande incidência de lesões no tornozelo faz-se necessário o entendimento de métodos de avaliação de baixo custo, que possam contribuir para a prevenção deste tipo de lesão em atletas. Objetivo: Nesse sentido, o presente estudo, tem como objetivo identificar os parâmetros de torque, atividade eletromiográfica, senso de reposicionamento articular e a pontuação em teste funcional em jogadoras de basquetebol com tornozelo estável. Correlacionar os valores de torque, atividade eletromiográfica e do senso de reposionamento articular com a pontuação dos testes funcionais em individuos saudáveis. Método: Participaram deste estudo 6 atletas do gênero feminino praticantes do basquetebol com idade entre 18 e 25 anos. As voluntárias realizaram os seguintes testes: torque isocinético concêntrico em inversão (INV) e eversão (EVE) nas velocidades de 60º e 120º, cinco testes funcionais e teste de reposicionamento articular com os ângulos-alvo de 10º e 20º de inversão. Após a verificação da normalidade de distribuição dos dados com o teste Shapiro-Wilk, utilizou-se o teste de Correlação Spearman para verificar a correlação dos testes funcionais com o pico de torque, o sinal EMG e o reposicionamento articular. Resultados: Não foi encontrados resultados esperados no estudo, exceto na correlação negativa para os valores de RMS do TA na velocidade de 120º nas contrações isocinética...(Resumo completo, clicar acesso eletrônico abaixo)
