Antibiotic prophylaxis for third molar extraction in healthy patients: current scientific evidence

Third molar extraction is one of the most frequently performed procedures in the dental clinic, and it is associated with innumerable trans- and postoperative complications, such as pain, trismus, edema, localized alveolar osteitis, and surgical site infection. Some authors advocate the use of local or systemic antibiotics to reduce the incidence of these postoperative complications. However, several studies have revealed an insignificant gain after using antibiotics. Despite the risks of allergic reactions, toxicity, and the development of resistant microorganisms, about 50% of dentists routinely prescribe the use of prophylactic antibiotics for this purpose. The goal of this paper is to evaluate the scientific evidence that justifies antibiotic prescription to healthy patients undergoing third molar extraction.

Enamel microabrasion: an overview of clinical and scientific considerations

Superficial stains and irregularities of the enamel are generally what prompt patients to seek dental intervention to improve their smile. These stains or defects may be due to hypoplasia, amelogenesis imperfecta, mineralized white spots, or fluorosis, for which enamel microabrasion is primarily indicated. Enamel microabrasion involves the use of acidic and abrasive agents, such as with 37% phosphoric acid and pumice or 6% hydrochloric acid and silica, applied to the altered enamel surface with mechanical pressure from a rubber cup coupled to a rotatory mandrel of a low-rotation micromotor. If necessary, this treatment can be safely combined with bleaching for better esthetic results. Recent studies show that microabrasion is a conservative treatment when the enamel wear is minimal and clinically imperceptible. The most important factor contributing to the success of enamel microabrasion is the depth of the defect, as deeper, opaque stains, such as those resulting from hypoplasia, cannot be resolved with microabrasion, and require a restorative approach. Surface enamel alterations that result from microabrasion, such as roughness and microhardness, are easily restored by saliva. Clinical studies support the efficacy and longevity of this safe and minimally invasive treatment. The present article presents the clinical and scientific aspects concerning the microabrasion technique, and discusses the indications for and effects of the treatment, including recent works describing microscopic and clinical evaluations.

Further Scrutiny of Scientific Whaling

Normile reports on Japan's expanded scientific whaling program and notes that "Canada, the United States, the Soviet Union, South Africa, and Japan were among several countries that [conducted scientific whaling] before 1982 [the year the IWC passed the worldwide commercial moratorium on whaling], but in recent years Japan has stood alone." Although true, this statement omits three equally important points.

Simulation of Ground-Water Flow in the Cedar River Alluvial Aquifer Flow System, Cedar Rapids, Iowa Scientific

The Cedar River alluvial aquifer is the primary source of municipal water in the Cedar Rapids, Iowa, area. Since 1992, the U.S. Geological Survey, in cooperation with the City of Cedar Rapids, has investigated the hydrogeology and water quality of the Cedar River alluvial aquifer. This report describes a detailed analysis of the ground-water flow system in the alluvial aquifer, particularly near well field areas. The ground-water flow system in the Cedar Rapids area consists of two main components, the unconsolidated Quaternary deposits and the underlying carbonate bedrock that has a variable fracture density. Quaternary deposits consist of eolian sand, loess, alluvium, and glacial till. Devonian and Silurian bedrock aquifers overlie the Maquoketa Shale (Formation) of Ordovician age, a regional confining unit. Ground-water and surface-water data were collected during the study to better define the hydrogeology of the Cedar River alluvial aquifer and Devonian and Silurian aquifers. Stream stage and discharge, ground-water levels, and estimates of aquifer hydraulic properties were used to develop a conceptual ground-water flow model and to construct and calibrate a model of the flow system. This model was used to quantify the movement of water between the various components of the alluvial aquifer flow system and provide an improved understanding of the hydrology of the alluvial aquifer.

Contesting Sphere Boundaries Online: Private/Technical/Public Discourses in Polycystic Ovarian Syndrome Discussion Groups

The internet is fast becoming a means for people to obtain information, creating a unique forum for the intersection of the public, technical, and private spheres. To ground my research theoretically, I used Jürgen Habermas’s sphere theory. Habermas (1987) explains that the technical sphere colonizes the private sphere, which decreases democratic potential. In particular, the internet is a place for altering technical colonization of the private and public spheres. My research focuses on women’s health because it is a particularly useful case study for examining sphere tensions. Historically, the biomedical health establishment has been a powerful agent of colonization, resulting in detrimental effects for women and their health. The purpose of this study is to examine how the internet encourages expert and female patient deliberation, which empowers women to challenge the experts and, thus, make conversations between the private/technical spheres more democratic. I used PCOS (Polycystic Ovarian Syndrome) as a case to observe the changing sphere boundaries by studying the discourse that took place on multiple patient and doctor websites over a four-year period. Through my research, I found that the PCOS women challenge the biomedical model by appropriating medical language. By understanding the medical talk, the women are able to feel confident when discussing their health conditions with the doctor and with each other. The PCOS women also become lay-experts who have personal and medical experience with PCOS, reducing private sphere colonization. This case study exemplifies how female empowerment can influence expert culture, challenging our conventional understanding of democracy.

No more than Conjectures: Popper and the Ethics of Scientific Enterprise

Karl Popper dealt with both problems Yurevich (Integrative Psychological and Behavioral Science, 43(2), 2009, doi:10.1007/s12124-008-9082-7) deals: the crisis in Psychology and in the discourse about the nature of science. Although he failed to provide a complete response for both problems, his proposals can yet be fruitful to the reflection on these matters in the context of the present discussion. He offers some tentative answers to what could be considered a healthy epistemic activity, something Yurevich does not provide. More interestingly, some of the Popper proposals seem to fit, and in some extent correct, the quest for ""collaborative work"" proposed by Zittoun et al. (Integrative Psychological and Behavioral Science, 43(2), 2009, doi:10.1007/s12124-008-9082-7) as a way of transforming crisis in development.

Landscape changes in Serra do Japi: legal protection or scientific expectation?

The creation of new legally protected areas brings many conflicts that distance the real landscape from the expected according to environmental law or conservation researchers. In this study, we mapped and compared the changes in Serra da Japi (Sao Paulo State, Brazil) throughout 40 years with scenarios of legal protection and scientific expectation on forest conservation, to evaluate the distance between them. This may allow us to infer the direction of historical changes and assist in the debate among decision makers. The results showed that most legal requirements on forest protection in the current landscape have been met. The 1960s was the period when the forest cover was closest to the desirable conservation stage. Although the Serra do Japi has maintained large areas of forests during the entire study period, human interference increased with the expansion of reforestation and urban areas, and access roads were identified as a primary potential driving forces of change. In addition, habitat loss was observed in the landscape, which can represent the first phase of a sequence of modifications detrimental to the environmental conservation of this protected area, including decision changes to land use. In conclusion, the changes evolved toward conservation expectations, but not toward the forest configuration of scientific expectation.

Alternatives exist: analysis of scientific literature in two Brazilian journals about the pedagogical work of Physical Education

Considering that the process of teacher training in universities takes into account the confrontation of knowledge produced by the scientific methods, the current study intended to identify what are the main contributions of the Brazilian scientific production of Physical Education teaching. Therefore, an exploratory study was done from the articles published on the subject in the two main periodicals of the area. The data analyzes allowed us to verify the relevancy of the knowledge produced and to suggest alternatives to its inclusion in the docent training programs.

Primary healthcare and the construction of meanings of oral health: a social constructionist interpretation of discourses of the elderly

Dentistry currently reveals itself to be open to new ideas about the construction of meanings for oral health. This openness leads to the social production of health revealing the contextualization of the social and historical aspects of the sundry knowledge in the development of oral health for different communities. With this research, we seek to build meanings for oral health with a group of elderly people. With this objective in mind, we propose an approximation between discourses on oral health mentioned by the elderly and the Social Constructionist discourse. We interviewed 14 elderly people enrolled in a Family Health Unit in Ribeirao Preto, State of Sao Paulo, in the first semester of 2010, and identified two interpretative repertoires through Discourse Analysis, which showed the relationship between 1 Lack of information and dental assistance in childhood, and 2 - Primary Health Care building the meaning of oral health. We concluded that Social Constructionism works epistemologically for the construction of meanings for oral health and that primary health is essential for appreciation and health care that enables the construction of meanings in oral health by the elderly that create conditions for self-care and healthy attitudes.

Scientific metaphors in the journalistic discourse

Scientific education and divulgation not only amplify people's vocabulary and repertory of scientific concepts but, at the same time, promote the diffusion of certain conceptual and cognitive metaphors. Here we describe this process and propose a classification in terms of visible, invisible, basic and derived metaphors. We focus our attention on physical metaphors applied to psychological and socio-economical phenomena, by studying two exemplar cases through an exhaustive exam of the online content of large Brazilian journalistic portals. Finally, we present implications and suggestions from Lakiff and Johnson's cognitive metaphor theory for the scientific education and divulgation process.

Scientific research output evaluation of professors of Sao Paulo State University, Marilia/SP

In this work, an analysis of scientific bibliographic productivity was made using the Faculdade de Filosofia e Ciencias, Universidade Estadual Paulista (FFC-UNESP) as example. It is composed by nine departments which offer altogether nine undergraduate courses: 1) Archival, 2) Library, 3) Speech Therapy, 4) Pedagogy, 5) International Relations, 6) Physiotherapy, 7) Occupational Therapy, 8) Philosophy, 9) Social Sciences and six graduate programs leading to M. S. and Ph.D. degrees. Moreover, when analyzing the different courses of FFC-UNESP, they represent typical academic organization in Brazil and Latin America and could be taken as a model for analyzing other Brazilian research institutions. Using data retrieved from the Lattes Plataform database (Curriculum Lattes) we have quantitatively the scientific productivity percentage of professors at UNESP. We observed that bibliometric evaluations using the Curriculum Lattes (CL) showed that the professors published papers in journal are not indexed by ISI and SCOPUS. This analysis was made using: 1) the total number of papers (indexed in Curriculum Lattes database), 2) the number of papers indexed by Thomson ISI Web of Science database and SCOPUS database, and 3) the Hirsch (h-index) by ISI and SCOPUS. Bibliometric evaluations of departments showed a better performance of Political Science and Economics Department when compared to others departments, in relation total number of papers (indexed in Curriculum Lattes database). We also analyzed the academic advisory (Master's Thesis and Ph. D. Thesis) by nine departments of FFC/UNESP. The Administration and School Supervision Department presented a higher academic advisory (concluded and current) when compared to the others departments.

THE SCIENTIFIC PRODUCTION OF PSYCHOSOCIAL CARE CENTERS

The objective of this study was to present a panoramic view of the scientific production regarding Psychosocial Care Centers (CAPS). This literature review was performed using the LILACS, MEDLINE, and SciELO databases. Sixty-eight references were selected, most of which were journal articles (88.24%) and studies related to final graduate study essays (10.29%); 75% of the references found dating from 2003 were included. The following are highlighted among the most frequent objectives: the analysis and evaluation of the new proposal for mental health care, represented by Psychiatric Reform and by CAPS, and the analysis of mental health professionals and their expectations towards the services. The authors hope the present review will help find pathways and implications that lead to new studies and practices in the everyday work of health care services.
