Conhecimento de mães sobre os procedimentos de emergência nos casos de avulsão dentária

Introduction: Despite tooth avulsion following trauma being relatively common in children, the available studies show that adults have limited knowledge about it. Aim: The purpose of this study was to assess, by a questionnaire, the mothers’ general knowledge about the immediate management of tooth avulsion. Material and method: This descriptive study was carried out on a convenient sample of mothers (n= 65) who participated of the “Pastoral da Criança”, from Araraquara, SP, Brazil. The questionnaire comprised 15 questions about personal data and knowledge on tooth avulsion management. Results: Participants were, on average, 35 years old. A total of 30.8% of the mothers reported that their children suffered dental trauma. The majority had never received advice on this subject (76.9%); and did not know how teeth are kept in the dental arch (69.2%). Almost a half of the sample believed that an avulsed tooth can be replanted (49.2%). In relation to the management of tooth avulsion, 40% of them would clean the avulsed tooth with water, even if it was not dirty (38.5%). Most of them (69.2%) would take the tooth by hand for cleaning purposes, regardless the tooth region; and believed that brushing the tooth was important to take the dirty out (67.7%). Conclusion: The general knowledge of mothers about the immediate management of tooth avulsion was considered inadequate endangering the successful treatment of tooth avulsion.

Capacidade de termoplastificação da guta-percha com diferentes conicidades

jObjective: The objective of this study was to evaluate the thermoplasticity of the gutta-percha cones used for root canal obturation: Dentsply convencional (Dentsply Ind. e Com., Petrópolis, RJ, Brazil), Dentsply 0.04, (Dentsply Ind. e Com., Petrópolis, RJ, Brazil), Antaeos 0.04 (VDW GmbH, Munich, Germany), ProTaper (Dentsply Ind. e Com., Petrópolis, RJ, Brazil) and Alfa 0.06 (VDW GmbH, Munich, Germany). Material and method: Specimens of each material (n = 10) were prepared after heating. After 24 hours were again heated to 70 °C and placed between two glass plates and subjected to a compression of 5 kg for 2 minutes. The scanned image of the groups before and after the compression was analyzed with the software Image Tool (UTHSCSA Image Tool for Windows version 3.0, San Antonio, TX, USA). The flow capacity of the different materials was determined by the difference between the initial and final area of each specimen. The results were submitted to ANOVA and Tukey test with significance level of 5%. Result: Among the material evaluated, the gutta-percha cones Alpha 0.06 and ProTaper presented more thermoplasticity than other groups (p < 0.05). The Dentsply gutta-percha presented thermoplasticity intermediate. The groups Dentsply 0.04 and 0.04 showed lower thermoplasticity after heating (p > 0.05). Conclusion: The gutta-percha present different property of thermoplasticity, which is important to selection of thermoplastic obturation techniques.

Prevenção do tabagismo na gravidez: importância do conhecimento materno sobre os malefícios para a saúde e opções de tratamento disponíveis

Objetivo: Examinar o padrão de consumo do tabaco e conhecimentos sobre as doenças relacionadas ao tabaco, assim como identificar os tipos mais populares de mídias entre gestantes para aprimorar estratégias para a prevenção e a cessação do tabagismo entre essas mulheres. Métodos: Estudo transversal com 61 gestantes atendidas em um hospital universitário e em unidades básicas de saúde em Botucatu, SP. A Escala Hospitalar de Ansiedade e Depressão foi aplicada a todas as participantes. Para aquelas com história de tabagismo, também foi aplicado o Teste de Fagerström para Dependência de Nicotina, e foi avaliado o grau de motivação para cessação tabágica nas fumantes. Resultados: Das 61 gestantes avaliadas, 25 (40,9%) eram fumantes (média de idade, 26,4 ± 7,4 anos), 24 (39,3%) eram ex-fumantes (média de idade, 26,4 ± 8,3 anos), e 12 (19,8%) nunca fumaram (média de idade, 25,1 ± 7,2 anos). A exposição passiva foi relatada por 39 gestantes (63,9%). Das 49 fumantes/ex-fumantes, 13 (29,6%) conheciam as consequências pulmonares do tabagismo; somente 2 (4,9%) conheciam os riscos cardiovasculares; 23 (46,9%) acreditavam que fumar não causa nenhum problema para o feto ou o recém-nascido; 21 (42,9%) consumiram álcool durante a gestação; 18 (36,7%) relataram aumento no consumo de cigarros quando bebiam; 25 (51,0%) experimentaram cigarros com sabores; e 12 (24,5%) fumaram narguilé. Entre as 61 gestantes avaliadas, a televisão foi o tipo de mídia mais disponível e favorita (85,2%), assim como a mais preferida (49,2%). Conclusões: Entre gestantes, o fumo ativo, o fumo passivo e o uso de formas alternativas de consumo de tabaco parecem ser altamente prevalentes, e tais mulheres parecem possuir poucos conhecimentos sobre as consequências do uso de tabaco. Programas educacionais que incluam informações sobre as consequências de todas as formas de uso de tabaco, utilizando formatos novos e efetivos para esta população específica, devem ser desenvolvidos para promover a prevenção/cessação do tabagismo entre gestantes. Amostras adicionais para explorar diferenças culturais e regionais são necessárias.

The electromagnetic gauge invariance in SU(3)L ⊗ U(1)N models of electroweak unification reexamined

Two models with SU(3)C ⊗ SU(3)L U(1)N gauge symmetry are considered. We show that the masslessness of the photon does not prevent the neutrinos from acquiring Majorana masses. That is, there is no relation between the VEVs of Higgs fields and the electromagnetic gauge invariance contrary to what has been claimed recently. © 1998 Elsevier Science B.V. All rights reserved.

Induction of luteolysis in mares utilizing a micro-dose of prostaglandin F-2 alpha in the sacral lumbar space

An experiment was conducted to examine the luteolytic effectiveness of using low or micro doses of PGF2α when administered at the BAI HUI acupuncture point, which is frequently used to treat ovarian disturbances in veterinary acupuncture. The results indicate that PGF2α given at a very low micro dose of 0.5 mg (one tenth the conventional recommended dose) administered at the BAI HUI acupuncture point located at the sacral lumbar space is equally effective at inducing luteolysis in mid-luteal phase mares as conventional PGF2α i.m. treatment using a tenfold higher dose. Therefore, based on the results of the present study, we suggest that the BAI HUI sacrai lumbar route somehow provides an extremely efficient pathway for the drug to the ovarian level.

The effect of self-adhesive and self-etching resin cements on the bond strength of nonmetallic posts in different root thirds

The purpose of this study was to evaluate the effect of self-adhesive and self-etching resin cements on the bond strength of nonmetallic posts in different root regions. Sixty single-rooted human teeth were decoronated, endodontically treated, post-space prepared, and divided into six groups. Glass-fiber (GF) posts (Exacto, Angelus) and fiber-reinforced composite (FRC) posts (EverStick, StickTeck) were cemented with self-adhesive resin cement (Breeze) (SA) (Pentral Clinical) and self-etching resin cement (Panavia-F) (SE) (Kuraray). Six 1-mm-thick rods were obtained from the cervical (C), middle (M), and apical (A) regions of the roots. The specimens were then subjected to microtensile testing in a special machine (BISCO; Schaumburg, IL, USA) at a crosshead speed of 0.5 mm/min. Microtensile bond strength data were analyzed with two-way ANOVA and Tukey's tests. Means (and SD) of the MPa were: GF/SA/C: 14.32 (2.84), GF/SA/M: 10.69 (2.72), GF/SA/A: 6.77 (2.17), GF/SE/C: 11.56 (4.13), GF/SE/M: 6.49 (2.54), GF/SE/A: 3.60 (1.29), FRC/SA/C: 16.89 (2.66), FRC/SA/M: 13.18 (2.19), FRC/SA/A: 8.45 (1.77), FRC/SE/C: 13.69 (3.26), FRC/SE/M: 9.58 (2.23), FRC/SE/A: 5.62 (2.12). The difference among the regions was statistically significant for all groups (p < 0.05). The self-adhesive resin cement showed better results than the self-etching resin cement when compared to each post (p < 0.05). No statistically significant differences in bond strengths of the resin cements when comparable to each post (p > 0.05). The bond strength values were significantly affected by the resin cement and the highest values were found for self-adhesive resin cement.

Characterization of the hemoglobins and globins of Synbranchus marmoratus Bloch, 1795 (Pisces, Synbranchidae)

1. 1. Total hemolysates of Synbranchus marmoratus Bloch, 1795, captured in Vitoriana, district of Botucatu, State of São Paulo, Brazil, were submitted to agar-starch gel electrophoresis on glass slides using 42 mM-Tris 1.7 mM EDTA-6.1 mM borate buffer, pH 8.8, for the gel and 10 mM borate-1.7 mM NaOH buffer, pH 8.6, for the cuvette. 2. 2. Three distinct hemoglobin bands were detected, with Hb I being of the cathodic type. 3. 3. Cellulose acetate electrophoresis in 800 mM Tris-2.1 mM EDTA buffer, pH 8.9, containing 6 M urea and 2.25 mM β-mercaptoethanol indicated the presence of four globin chains denoted α 1, α 2, β and γ. 4. 4. It is suggested that the probable tetrameric constitution of the hemoglobin of Synbranchus marmoratus Bloch, 1795 is Hb I (α 2 2γ 2), Hb II (α 2 1γ 2) and Hb III (α 2 1β 2). © 1986.
