Atividade antimicrobiana de cimentos endodônticos

The antimicrobial activity is a fundamental property of root-canal sealers due to persistence of residual microorganisms in the root canal system, even after the chemo-mechanical preparation and using of intracanal dressing. The aim of this study is to review the literature about the antimicrobial properties of some of the main root-canal sealers. Although there is controversy regarding this property, probably due to differences in the methodologies used in the studies, it was concluded that the sealers with the best antimicrobial activity were (in ascending order): Endofill, Ketac Endo, Sealapex, AH Plus, Endo CPM Sealer, Sealer 26 and Epiphany. Activ GP still needs scientific research to evaluate this property.

Ética e atuação profissional: percepção de agentes comunitários de saúde

The perceptions of the Community Health Agent (CHA) referred to ethics in their work have been evaluated in this study. A questionnaire with social and ethical issues was applied in 61 ACS. 90% reported having received information about ethics, and “training courses” was the most cited source (68.9%). On a scale from 1 (least) to 5 (maximum), 67% claimed to have knowledge about ethics among 4 or 5 and 88.5% reported that this topic has an importance of 5 in their work. Ethical conflicts exposed had an average of 75% of respondents in agreement with the reference sources, and the two items involving “information privacy” showed the greatest disagreement. Ethics was considered important by the professional performance of subjects who had a good perception about the issue; however the topic about privacy of information generated controversy.

A influência do anel na evolução ponderal após quatro anos da derivação gátrica em Y-de-Roux laparoscópica

Use of ring in Roux-en-Y gastric bypass is still a matter of controversy among bariatric surgeons. There is no consensus on its impact in relation to weight loss and weight maintenance in the long term. AIM: To evaluate the influence of the ring on the evolution of body weight over four years after bariatric surgery. METHODS: Retrospective analyzis of 143 women who underwent laparoscopic Roux-en-Y gastric bypass paired on the use or not use of Silastic® ring. Follow-up time was 48 months. Inclusion criteria were age over 18 years, primary bariatric operation and regular attendance at the clinic during the period of interest for research. The technique kept small gastric reservoir estimated in a volume of 30 ml. The food limb had in average 150 cm and the bile one 40 cm from the duodenojejunal angle. The group "ring" used Silastic® device with length of 6.5 cm, placed 2 cm from gastrojejunal anastomosis. The ring was closed for five polypropylene surgical thread sutures. In the morning after surgery the patients received isotonic fluids; on the second day salty liquid diet and were discharged on the third day. Semisolid diet started from the 20th day and solid on the 30th, with daily tablet of polivitamins. RESULTS: The weight loss was larger on the ring than without ring groups in all periods, respectively 10% and only 5% in the third postoperative year. The proportion of not having reached the 50% excess weight loss expectative was significantly higher in the group without ring than in the group with the ring (31% and 8% respectively in the fourth year). There was no difference between groups in delayed recovery of weight lost with the operation. CONCLUSIONS: The results were favorable to use the ring exclusively when it is analyzed only the weight loss.

A constituição de uma questão sociocientífica em um grupo de professores: um processo polifônico de desvelamento da realidade concreta

This article presents part of a broader research and seeks to elucidate the process of setting up a Socio-scientific Issue in a group of teachers at a public school. Assuming that a Socioscientific Issue must aggregate those involved in the educational process in situations of dialogue, argumentation and construction of a positioning, we understand that the recognition of the controversy or of the legitimacy of the theme in the context at stake is crucial to achieving the desired goals. Thus, starting from subsidies from the Critical Theory of Society, we characterize the process of setting up a Socio-scientific Issue among teachers as an exercise of unveiling the concrete reality, listing problematic, controversial and open to criticism aspects of Science and Technology. Thus, the Socio-scientific Issue is listed out in the group as soon as it is established a polyphonic dialogue where all participants stand, recognize the fertility of the themefor the intendededucational context and can speak of it with propriety.

Improving business innovation and research through the application of neuromarketing with ethics: a framework

The objective of this paper is to analyse and to discuss the ethical issues in the field of research known as neuromarketing, a tool used to improve innovation in companies. It uses techniques available to neuroscientists, both newer and more sophisticated ones along with traditional ones, but now for new purposes. From the beginning, this new area has evoked discussions about ethical aspects related to the results presented. Despite the unrestricted controversy surrounding the theme, few studies have discussed ethical issues involved in this line of research in a pragmatic manner. In this sense, this paper seeks to analyse and discuss ethical issues in neuromarketing research through a literature review and the proposal for a framework of ethical mapping. This framework revealed the ethical implications that would be most prominent in certain research situations: the purpose of utilising neuromarketing techniques, organisational type, and industrial sector, among others.

Orientação sexual:concepções sobre sexo em pré-adolescentes

Sexual Orientation is present in the curriculum of many schools for elementary and high school. This subject generates controversy in the school community. This a fact that leads many teachers postpone the start of this topic. Fifty students participated in this study, 24 boys and 26 girls with average age of eleven years. The study aimed to investigate conceptions on sex in adolescents using the cartoon. The analyzed results suggest that students understand sex as intercourse only. However, there are a multitude of features mentioned by students. These are issues that require further reflection about issues not always discussed in class: pregnancy and abortion, condom use, sexual desire, anal sex, becoming a single mom, group sex, AIDS, prostitution, size of genitals, masturbation, among others.
