Henriques, águida Cristina Gomes;Cazal, Claudia;Castro, Jurema Freire Lisboa de;
Revista do Colégio Brasileiro de Cirurgi?es , 2010, DOI: 10.1590/S0100-69912010000400011
Abstract: low energy laser has been used as an adjuvant therapy or as a therapeutic tool in many different areas of dentistry. it is recognized by its anti-inflammatory and analgesic properties, and also as a tissue repair inductor. low intensity laser property in stimulate cell proliferation during wound healing and its biomodulation mechanisms are discussed in this paper. these properties have already been established for cultured benign cells, but there is a controversy when extended to the spectrum of the malignant neoplastic process, normally generating great discussions. the objective of this work was to perform a literature review about the low intensity laser capacity in induce cell proliferation. the discussion is specially concerned about its effects on malignant cells.
RSE et théorie des parties prenantes : les impasses du contrat CSR and stakeholder theory: the deadlocks of the contract RSE y teoría de las partes que la asumen : los impasses del contraste
Didier Cazal
Revue de la Régulation : Capitalisme, Institutions, Pouvoirs , 2011,
Abstract: Cet article traite de la théorie des parties prenantes et de ce qu’elle implique pour la recherche sur la RSE et les pratiques en la matière. Tout d’abord, certaines faiblesses conceptuelles et théoriques sont relevées. Nous soulignons ensuite l’enracinement de la théorie des parties prenantes dans le contractualisme : une conception de la firme en termes de n uds de contrats entre parties prenantes, inspirée de la théorie des co ts de transaction, une justification plus philosophique par les théories du contrat social et de la justice comme équité, inspirée des travaux de Rawls. Nous pointons les problèmes théoriques que cet enracinement contractualiste soulève avant d’en questionner les implications sociopolitiques. Fonder la RSE sur des conceptions inspirées de la théorie des parties prenantes risque de conduire à un libéralisme élargi, au volontarisme en matière de RSE et en définitive à une moralisation limitée d’un capitalisme débridé. The paper examines stakeholder theory and what it means for CSR research and practices. First, some theoretical and conceptual weaknesses are pinpointed. Then I underline how stakeholder theory is rooted in contractarianism: the firm is viewed as a nexus of contracts between stakeholders, in the line of transactions costs theory, its philosophical foundations are inspired from social theories of social contract and justice as fairness, as they were especially developed by Rawls. I show the conceptual problems inherited from such contractarian views and finally examine the likely sociopolitical consequences of these views. Grounding CSR in stakeholder theory may well result in some extended free-market liberalism and in voluntarism regarding CSR matters and eventually in limited ethical version of an unbridled capitalism. Este artículo trata de la teoría de las partes involucradas y de lo que ello implica para la búsqueda acerca de la RSE y las prácticas en la materia. En primer lugar, ciertas debilidades conceptuales y teóricas son puestas en evidencia. Nosotros destacamos a continuación las relaciones de la teoría de las partes involucradas en el estructuralismo ; una concepción de la firma en términos de nudos de contratos entre las partes involucradas, inspirada en la teoría de los costos de transacción, una justificación más filosófica por parte de las teorías del contrato social y de la justicia como equidad, inspirada en los trabajos de Rawls. Puntualizamos los problemas teóricos que esta vinculación contractualista pone de relieve antes que cuestionar las implicaciones sociopolíticas. Fundar la RSE sobre conc

International Journal of Dentistry , 2010, DOI: 10.1155/2010/780670
Abstract: The purpose of this research was to evaluate the maximum stress around osseointegrated implants and alveolar ridge, in a mandible with left partial resection through a photoelastic mandibular model. The first group consisted of two implants: traditional model (T), implants placed in the position of both canines; fulcrum model (F), implants placed in the position of left canine CL and right lateral incisor LiR. Both models linked through a bar and clips. The second group was consisted of three implants, with implants placed in the position of both canines (CR and CL) and the right lateral incisor (LiR), which composed four groups: (1) model with 3 “O” rings, (2) model 2 ERAs, bar with clips, (3) model 2 ERAs bar without clips; (4) model “O” ring bar and ERA. An axial and an oblique load of 6.8?kgf was applied on a overdenture at the 1st Pm, 2nd Pm, and 1st M. Results showed that the area around the left canine (CL) was practically free of stress; the left lateral incisor (LiL) developed only small tensions, and low stress in all the other cases; the right canine tooth suffered the largest concentrations of stress, mainly with the ERA retention mechanism. 1. Introduction The prosthodontic rehabilitation of edentulous patients has been used over the years primarily for esthetics purposes after mandible resection. The development of osseointegrated implants allowed the production of more stable overdentures, improving retention and stability, thereby improving prosthetic rehabilitation prognosis and oral function. Some researchers demonstrated the use of the photoelasticity to evaluate the stress of bodies subjected to efforts [1–4]. Other studies have exalted the success of the osseointegrated implants [5–8] pointing out their advantages in supporting overdentures. Some authors also [9] referred to the improvement of the dental prosthetic therapy with the use of two implants linked through a bar. Other fact, which must be considered, is the biting force, that increases three times more with the use of overdentures based on implants, when compared with conventional dentures. Some studies referred to the use of implant-supported prosthesis to compensate partially problems that arose from partial resection of the mandible [7, 8, 10]. It is of great interest to know the tensions of the implants, also in cases of overdentures in patients with partial resection of mandible. Recent studies, using the method of photoelasticity [1, 2, 4, 11], have demonstrated the tensions in implant-supported prostheses, in which the largest tensions were found in the distal

Almeida, Fernanda Campos Sousa de;Cazal, Claudia;Pucca Júnior, Gilberto Alfredo;Silva, Dorival Pedroso da;Frias, Antonio Carlos;Araújo, Maria Ercilia de;
Brazilian Dental Journal , 2012, DOI: 10.1590/S0103-64402012000300010
Abstract: this study presents the strategies for prevention and early detection of oral cancer by means of screening in the elderly population of s?o paulo, the richest and the most populous state of brazil. this research was a retrospective longitudinal study based on the analysis of secondary data. the variables - number of participating cities, coverage of screening, and number of suspicious and confirmed cases of oral cancer - were divided into two periods: 2001-2004 and 2005-2008. data were analyzed statistically by the chi-square test at 5% significance level. the implementation of a nationwide public oral health policy in 2004 and the reorganization of the secondary and tertiary health care were evaluated as mediator factors able to interfere in the achieved outcomes. from 2001 to 2008, 2,229,273 oral examinations were performed. there was an addition of 205 participating cities by the end of the studied period (p<0.0001). the coverage of oral cancer screening increased from 4.1% to 16% (p<0.0001). there was a decrease in the number of suspicious lesions (from 9% in 2005 to 5% in 2008) (p<0.0001) and in the rate of confirmed oral cancer cases per 100,000 examinations (from 20.89 in 2001 to 10.40 in 2008) (p<0.0001). after 8 years of screening, there was a decrease in the number of suspicious lesions and confirmed cases of oral cancer in the population. the reorganization of secondary and tertiary health care levels of oral care seems to have contributed to modify these numbers, having a positive impact on the outcomes of oral cancer screening in the s?o paulo state.

Abstract: the present essay is involved in the construction of the participation of civil society organized in health as a citizenship exercise and the place of municipal health council (mhc) in this participation process. the study has as objective to analyze the institutional pattern of the mhc of vi?osa, minas gerais state, approaching the structure and operation dynamics, composition rules and competences. it is related to the observational study of traverse stamp, where individual interviews with the counselors of health, non participative direct observation of meetings of the mhc and documents were used as instrument of analysis. a number of 34 members (77,2%) of the respective council were interviewed. among the results, it stands out that 44,2% of the interviewed said that the decisions taken in the mhc are not informed to the population and 35,3% does not transfer the information of the proposals and discussions taken in the mhc for discussion and deliberation for their pairs. for the documental analysis, it was verified that the composition of the mhc of vi?osa is not in agreement with the foreseen distribution by the federal legislation. the results suggest the existence of problems related to the representation, limiting the social participation in the councils.
Participa??o, Controle Social e Exercício da Cidadania: a (des)informa??o como obstáculo à atua??o dos conselheiros de saúde

Abstract: to strengthen the exercise of social control in health politics, it is really necessary to know the unified health system; the legislation; the epidemiological reality, assistance, financial, political, and so on. in this sense, this paper aims to analyze the level of information and knowledge of the municipal health counselors in the city of vi?osa, minas gerais state, concerning their attributions and functions. the elements of analysis of the study were semi-structured interviews conducted from april to july 2006, and the direct observation of meetings. from 44 counselors, 34 (77.3%) were interviewed, 17 (50%) are users' representatives; eight (23.5%) are representatives of the municipal government; seven (20.6%) are representatives of the service; and two (5.9%) are representatives of health professionals. it can be noticed that 41.2% of counselors ignore the internal regiment, what could hinder the fulfillment of their competences. the health plan is not used for evaluation of health actions and services for the counselors, because most of them (73.5%) declared not having read it. the possibility of counselors helping supervise the financial and budgetary executions of the municipal health fund restrains it, since 67.6% of the interviewees cannot analyze the administration report; 79.4% of the counselors never received training and 85% told need being qualified to act in the council. participation and social control provide transparence to the public good and, based on the premise that one can only control what one knows, the need of continuing training courses for counselors is confirmed.
