Justiça restaurativa no sistema penal e processual penal como forma de concretização do estado democrático constitucional

Diante do atual modelo penal e processual penal não atender aos reclamos das partes interessadas, gerando um descrédito na Justiça de um modo geral, surge a Justiça Restaurativa como uma alternativa para solucionar tais problemas e como elemento de concretização do Estado Democrático Constitucional. A Constituição Federal de 1988 representa o símbolo maior do processo de democratização e de constitucionalização nacional. O Princípio da Dignidade da Pessoa contida no texto constitucional consiste num dos principais fundamentos da República Federativa do Brasil, funcionando como respaldo aos direitos e garantias fundamentais do cidadão, sobretudo na seara criminal. A partir do processo de constitucionalização nacional, ocorre uma releitura das legislações infra-constitucionais, que passam a ser interpretadas de acordo com o texto constitucional. Atualmente, a conjuntura jurídico-penal pátria está associada à ideia de garantismo, ligada ao conceito de Estado Democrático Constitucional. Apresenta-se a Justiça Restaurativa como um novo modelo de Justiça Penal, mais flexível e humanizado, visando além da aplicação da pena imposta pelo Estado, superar uma situação de conflito, na busca por resultados positivos no combate e redução da criminalidade, a satisfação da vítima e a mudança da cultura de violência, compatível com as diretrizes do Estado Democrático Constitucional. A partir da análise do direito internacional e de projetos e legislações nacionais envolvendo a Justiça Restaurativa, percebe-se a eficácia das medidas restaurativas na solução de conflitos dentro do Processo Penal, além da satisfação da vítima, do infrator e de familiares na participação dos encontros restaurativos, constituindo ferramenta de satisfação da dignidade humana, dentro de uma perspectiva humanista e garantista

A palavra cantada nos espaços intersubjetivos de um centro de atenção psisossocial do município do Natal/RN

The psychiatric care and mental health are undergoing constant change over the History. The Brazilian Psychiatric Reform, which brings up the deinstitutionalization as a structuring in the restorative care process. The Reform has as one of the mainly substitutive services the Centers for Psychosocial Care (CAPS), which work from the Singular Therapeutic Project (PTS) in order to restore the autonomy and restore the dignity of users. The therapeutic workshop is some of the resources used and work several kinds of activities as: writing, handcraft, music, poetry, and so forth. This study set up to apprehend the social representations of helping of the music workshop carried out in the CAPS II east of Natal/RN, from the reports given by the participants of the workshop, using the focal group as technique. This is a descriptive exploratory study with a qualitative approach. A total of 16 users participated in four musical therapeutic workshops from April to May 2010. The study was approved by the Ethics and Research Committee of UFRN. The discursive material from the workshop was submitted to the informational resource of Analyse Lexicale par Contexte d um Ensemble de Segments de Texte, ALCESTE, and analyzed based on the Theory of Representations and the Central Core Theory. The majority of subjects were men (62.5%), single (62.5%), aged 40-49 years (37.6%) and elementary school level (56.2 %). The reports were transcribed and submitted to the classification system of ALCESTE, which elected the following categories: Category 1 - Experience in the Word Family Sung, Category 2 - Musical Experiences and Approaches, and Category 3 - Feelings and emotions evoked by music. The representation of these individuals is anchored in the experience they have with the CAPS, lived and socialized by common sense, through this particular social group workshop objectified in music therapy as a therapeutic modality enjoyable. The central core revealed the intrinsic relationship between users and the music, establishing a relationship of openness to use the same while its therapeutic use in workshops of substitute services for mental health. Peripherals elements issues are related to listen, share and experience music in the family. Intermediary Elements relate to the feelings and emotions evoked by music, given her close relationship with it. It was found in the study that music can be construed as an artifact of good therapeutic responsiveness to users, configuring it as an invigorating and enjoyable therapy, confirming the need for continuity of this activity, as well as its expansion into the service

Atuação profissional e vivência do cirurgião-dentista na estratégia do programa de saúde da família

The purpose of this research was to analyze the working profile of dentists from the Family Health Program (PSF Programa de Saúde da Família, Brasil) of some Municipal Districts of Rio Grande do Norte (Brazil) in order to understand the way they handle the experience acquired with the work developed in that Program. This discussion evolves a reflection about the perspectives of consolidation of the FHP as well as the possible advancements of the Brazilian Unified Health System (SUS - Sistema Único de Saúde). The target population was composed of dentists from the FHP of Rio Grande do Norte. Thus we performed twenty-one interviews orientated by a semi-structured guidebook with open questions and identification data. We opted for recording the speech of all the professionals in order to ensure the accuracy of the information gathered. The main results found were: predominance in the female gender; the majority of dentists has no post graduation courses; in those few cases of dentists with some post-graduation a lack of correlation with Public or Collective Health was observed; the dentists interviewed present a profile directed to clinical activities; the dentists used to develop basic restorative and periodontic treatment, simple surgeries and educative and preventive activities, even though the last two ones are carried out in an extremely traditional way (lectures and topical application of fluoride). In addition, as biggest difficulties to manage the work dentists pointed out the lack of permanent and consumer material, inadequate infrastructure, no transport to take them to distant places, no integration with the Health Family Team, technical difficulty such to perform educative and preventive activities as to provide adequate service to a repressed lawsuit. The results indicate the existence of a necessity to lead them to reflect and redirect their practices. In order to reach this aim it must be considered as initial measure the investment and encouragement toward to permanent education as well as a close follow-up and evaluation of the actions developed by them

Praça: lugar de lazer: relações entre características ambientais e comportamentais na Praça Kalina Maia Natal RN

Nowadays, the urban chaos brings some problems to the citizens such as mental fatigue, irritability and lack of attention, emphasizing the need for open urban spaces, capable to contribute to the restoration of physical and mental balance of people. By the variety of alternative uses available, many of them related to the stimulus of entertainment activities, the squares have been identified as restorative environments, especially by its potential as a place of leisure. In this context, the objective of this dissertation is to understand the use of the square as leisure environment, by a square in Natal RN, establishing the relationship between environmental and behavioral characteristics. More specifically, I attempt to identify the major activities that happen there, the people that develop them and the spatial and temporal configurations of this occupation. Among the 290 squares available in the city, the Kalina Maia Square was selected, which is located in the district of Lagoa Nova. The case study chosen was based on criteria relating to scale, shape, location on the urban environment, variability of uses and conservation status. In the study were used behavioral mapping place-centered and people-centered, behavior trace analysis and 14 interviews. The results show that the square is used by people from different ages and social classes, subdivided into groups with specific days and times. These users are usually engaged in activities related to various types of leisure, with sports predominance. The relationship between spatial configuration and behavior shows that there is a sectorization of uses, being possible to identify the environmental characteristics that most favor observed activities, especially in relation to shading and presence of furniture and equipment. Moreover, throughout the day it appears that the affordances inherent to the various fixed objects on the square are decoded differently by various categories of users, by giving them insights that help the development of leisure activities that characterize each group

Stability analysis of power systems described with detailed models by automatic method

The power system stability analysis is approached taking into explicit account the dynamic performance of generators internal voltages and control devices. The proposed method is not a direct method in the usual sense since conclusion for stability or instability is not exclusively based on energy function considerations but it is automatic since the conclusion is achieved without an analyst intervention. The stability test accounts for the nonconservative nature of the system with control devices such as the automatic voltage regulator (AVR) and automatic generation control (AGC) in contrast with the well-known direct methods. An energy function is derived for the system with machines forth-order model, AVR and AGC and it is used to start the analysis procedure and to point out criticalities. The conclusive analysis itself is made by means of a method based on the definition of a region surrounding the equilibrium point where the system net torque is equilibrium restorative. This region is named positive synchronization region (PSR). Since the definition of the PSR boundaries have no dependence on modelling approximation, the PSR test conduces to reliable results.

Fatores socioeconômicos contextuais associados à condição bucal de adolescentes no Brasil

Many surveys are conducted comparing oral health conditions with individual variables, such as socioeconomic and demographic factors. However, in the same way that individuals differ among themselves, the groups also have their own characteristics and the effects of this differentiation must be researched. Brazil, despite being one of the major economic powers of the world and shows an improvement in the average value of its health indicators, is also one of the most unequal and remains among the countries with the greatest health inequities. The purpose of this study was to investigate the importance of social determinants on the contextual level oral health among Brazilian adolescents, population not much researched by the literature. The research was made using an ecological approach in order to identify possible inequalities between cities and capitals. Using data from SBBrasil 2010 it was evaluated less common outcomes (loss of first molar, dental care index and T-Health) which provide information on the degree of morbidity of caries and health level of dental tissues, in addition to analyze the related services. The association of these oral health indicators with socioeconomic factors such as income, employment, education and inequality, collected from Census 2010, was analyzed by simple and multiple linear regressions. The study included the 27 state capitals and four clusters representing the municipalities of the country. It was possible to see better access to services in locations with better income distribution. However, the strong association of contextual factors related to poverty, low levels of education and poor housing and jobs with poorer levels of oral health in adolescents seems to overshadow the effects of income inequalities on dental caries in the country. In some locations, particularly within the North and Northeast, whichever one keeps dentistry mutilating, whose effects are already noticeable in its adolescent population. Access to restorative services in Brazil remains limited and unequal. The results of this study highlight the inequities in oral health in the country and show the need of the inclusion of new perspectives on the traditional approach of Preventive Dentistry and education models in Dentistry. Tackling health inequalities in oral health in the country requires the cooperation of various actors involved in the process and the inclusion of oral health in the context of overall health. The social determinants approach, as well as evaluating the distribution of oral diseases in the country and its inclusion in the context of overall health, should guide the implementation of programs and oral health practices in order to contribute to the reduction of inequalities

Genotoxicity and cytotoxicity of glass ionomer cements on Chinese hamster ovary (CHO) cells

Glass ionomer cements are widely used in dentistry as restorative materials and adhesives for composite restorations. However, the results of genotoxicity studies using these materials are inconclusive in literature. The goal of this study was to examine the genotoxic and cytotoxic potential of three different glass ionomer cements available commercially (Ketac Cem, Ketac Molar and Vitrebond) by the single cell gel (comet) assay and trypan blue exclusion test, respectively. For this, such materials were exposed to Chinese hamster ovary (CHO) cells in vitro for 1 h at 37 degrees C. Data were assessed by Kruskall-Wallis nonparametric test. The results showed that the powder from Ketac Molar displayed genotoxicity only in the maximum concentration evaluated (100 mu g/mL). In the same way, the liquid from Vitrebond at 0.1% dilution caused an increase of DNA injury. Significant differences (P < 0.05) in cytotoxicity provoked by all powders tested of glass ionomer cements were observed for exposure at 1000 mu g/mL concentration. With respect to liquids of glass ionomer cements evaluated, the major toxic effect on cell viability was produced at 10%, beginning at the dilution of 0.5% for Vitrebond. Taken together, we conclude that some components of glass ionomer cements show both genotoxic and cytotoxic effects.

Biocompatibility of glass-ionomer cements using mouse lymphoma cells in vitro

Glass-ionomer cements are widely used in dentistry as restorative materials and adhesives for composite restorations. A number of genotoxicity studies have been conducted using these materials with results conflicting so far. Thus, the approach was aimed to look at the genotoxic and cytotoxic potential of three different glass-ionomer cements available commercially (Ketac Cem, Ketac Molar and Vitrebond) by the single cell gel (comet) assay and trypan blue exclusion test, respectively. For this, such materials were exposed to mouse lymphoma cells in vitro for 1 h at 37 degrees C. Data were assessed by Kruskall-Wallis non-parametric test. The results showed that all powders assayed did not show genotoxic effects. on the other hand, the liquid from Vitrebond at 0.1% dilution caused an increase of DNA injury. Significant statistically differences (P < 0.05) in cytotoxicity provoked by all powders tested were observed for exposure at 1000 mu g mL(-1) concentration and 100 mu g mL(-1) for Ketac Molar. With respect to liquids of glass-ionomer cements evaluated, the major toxic effect on cell viability was produced at 1%, beginning at the dilution of 0.5% for Vitrebond. Taken together, these results support the notion that some components of glass-ionomer cements show both genotoxic and cytotoxic effects in higher concentrations.

An alternative technique to the harvesting of a connective tissue graft from a thin palate: Enhanced wound healing

This article describes an alternative surgical approach to the harvesting of subepithelial connective tissue grafts from thin palates. A partial-thickness flap is raised, and a graft composed of epithelium and connective tissue is removed from the palate. The superficial layer ( epithelium and a thin zone of connective tissue) is then dissected from the graft and replaced at the donor site to facilitate faster healing. The subjacent layer of connective tissue is placed as needed to obtain root coverage. The clinical application of this technique is described in two patients with multiple gingival recessions.

Periodontal tissue response to coverage of root cavities restored with resin materials: A histomorphometric study in dogs

Background: the purpose of this study was to histomorphometrically evaluate the response of periodontal tissues covering Class V resin restorations in dogs.Methods: After raising a mucoperiosteal flap, bony defects measuring 5 x 5 mm were created on the buccal aspect of the canines of five dogs followed by cavity preparations on the root surface measuring 3 x 3 x 1 mm. Before repositioning the flap to cover the bone defect, the cavities were restored with composite resin (CR) or resin-modified glass ionomer cement (RMGIC) or were left unrestored as control (C). The dogs were euthanized 90 days after surgery. Specimens comprising the tooth and periodontal tissues were removed, processed routinely, cut into longitudinal serial sections in the bucco-lingual direction, and stained with hematoxylin and eosin (H&E) or Masson's trichrome. The most central sections were selected for histomorphometric analysis.Results: Histomorphometric analysis revealed apical migration of epithelial tissue onto the restorative materials (RMGIC and CR). The C group presented significantly longer connective tissue attachment (P < 0.05) than the RMGIC and CR groups and significantly higher bone regeneration (P < 0.05) compared to the RMGIC group. Histologically, the cervical third (CT) of all groups had the most marked chronic inflammatory infiltrate.Conclusions: Within the limits of this study, it can be concluded that the restorative materials used exhibit biocompatibility; however, both materials interfered with the development of new bone and the connective tissue attachment process.

Influência da aplicação de flúor sobre a rugosidade superficial do ionômero de vidro Vitremer e adesão microbiana a este material

Os cimentos ionoméricos representam importante opção de material restaurador em Odontologia e sua adesão à estrutura dental, diminuindo a infiltração marginal, somada à liberação de flúor, inibindo o metabolismo de microrganismos acidogênicos e favorecendo a remineralização dental, podem diminuir a ocorrência de cárie secundária. A aplicação tópica de géis acidulados ou neutros contendo flúor tem sido largamente utilizada em Odontologia. No entanto, este procedimento pode afetar a integridade dos materiais restauradores, aumentando sua rugosidade e a retenção de placa bacteriana. Dessa forma, o presente estudo avaliou o período de tempo no qual o cimento ionomérico Vitremer mantém sua capacidade inibitória sobre Streptococcus mutans ATCC 25175 e a adesão dos mesmos sobre a superfície do material, bem como a influência da aplicação tópica de flúor acidulado e neutro sobre esses parâmetros microbiológicos e as características superficiais daquele material. Verificou-se que a atividade antimicrobiana do cimento ionomérico Vitremer se mantém por aproximadamente quatro dias e não é recuperada com o uso de flúor gel acidulado ou neutro. Observou-se, também, que Streptococcus mutans ATCC 25175 adere ao material restaurador testado sendo que a aplicação tópica de flúor não influenciou esta adesão. As características superficiais desses materiais não se alteraram com a aplicação dos géis.

Correction of a Mucogingival Defect Using an Implant-Retained Postoperative Stent in a Severely Resorbed Mandible: Case Report

This case report describes a technique that uses a palatal mucosal graft and an acrylic resin postoperative stent in an attempt to increase the layer of keratinized tissue around osseointegrated implants in an atrophic mandible. During second-stage surgery a split-thickness labial flap is reflected and apically repositioned by being sutured onto the periosteum and connective tissue. A palatal mucosal graft is then sutured onto the recipient site. The stent is worn for at least 4 weeks following surgery. This procedure helps to eliminate mobility of the mucosa in the area, deepen the vestibule, and prevent muscle reinsertion. (Int J Periodontics Restorative Dent 2008;28:617-623.)

Periodontal and Prosthetic Biologic Considerations to Restore Biological Width in Posterior Teeth

\ The biologic width is an essential dental space that always needs to be maintained to ensure periodontal health in any dental prosthetic restorations. An iatrogenic partial fixed prosthesis constructed in lower posterior teeth predisposed the development of subgingival caries, which induced violation of the biologic width in involved teeth, resulting in an uncontrolled inflammatory process and periodontal tissue destruction. This clinical report describes a periodontal surgical technique to recover a violated biologic width in lower posterior teeth, by crown lengthening procedure associated with free gingival graft procedure, to ensure the possibility to place a modified partial fixed prosthesis in treated area. The procedure applied to recover the biologic width was crown lengthening with some modifications, associated with modified partial fixed prosthesis to achieve health in treated area. The modified techniques in both surgical and prosthetic procedures were applied to compensate the contraindications to recover biologic width by osteotomy in lower posterior teeth. The result, after 4 years under periodic control, seems to achieve the projected goal. Treating a dental diseased area is necessary to diagnose, eliminate, or control all etiologic factors involved in the process. When the traditional methods are not effective to recover destructed tissues, an alternative, compensatory, and adaptive procedure may be applied to restore the sequelae of the disease, applying a restorative method that respects the biology of involved tissues.

Clinical Evaluation of the Effectiveness of Different Bleaching Therapies in Vital Teeth

The aims of this in vivo study were to compare the effectiveness and color stability of at-home and in-office bleaching techniques and to evaluate whether the use of light sources can alter bleaching results. According to preestablished criteria, 40 patients were selected and randomly divided into four groups according to bleaching treatment: (1) at-home bleaching with 10% carbamide peroxide, (2) in-office bleaching with 35% hydrogen peroxide (HP) without a light source, (3) in-office bleaching with 35% HP with quartz-tungsten-halogen light, and (4) in-office bleaching with 35% HP with a light-emitting diode/laser. Tooth shade was evaluated using the VITA Classical Shade Guide before bleaching as well as after the first and third weeks of bleaching. Tooth shade was evaluated again using the same guide 1 and 6 months after the completion of treatment. The shade guide was arranged to yield scores that were used for statistical comparison. Statistical analysis using the Kruskal-Wallis test showed no significant differences among the groups for any time point (P > .01). There was no color rebound in any of the groups. The bleaching techniques tested were equally effective. Light sources are unnecessary to bleach teeth. (Int J Periodontics Restorative Dent 2012;32:303-309.)
