Dental education is going through important changes in preparing workers to meet the needs of the society and the labor market. For that reason, we studied the offering of comprehensive dental care clinics in Brazil with the aim of encouraging future curriculum changes focused on the training of general dental practitioners. An email questionnaire on educational organization and comprehensive care clinics of undergraduate programs was sent to each academic dental affairs dean. Sixty-seven (41.6%) dental schools agreed to participate. We observed that curriculum changes have contributed to modify the format of comprehensive care clinics. This was felt mainly (88,1%) with regards to workload and course offerings in different levels of the dental curriculum, thereby creating a favorable environment for generalist training. Most schools shared the following characteristics: clinical procedures were being prioritized according to level of complexity (95,5%), students were having the chance to attend courses in other programs (37,3%), and attempt to diversify teaching methods was being challenged (58,2%). Although progress in combining teaching and clinical services was reported by 83,6% of schools, most clinical procedures were still being performed intramurally (50,7%) in partnership with public service. There was also improvement in clinical mentorship due to the hiring of instructors qualified to work in comprehensive care clinics and with aptitude to supervise a wider range of dental procedures (58,2%). Further changes to Brazilian comprehensive care clinics should hence be encouraged and intensified to ensure appropriate generalist training for dental practitioners

Proposals that aim a redirection of current health attention models in Brazil are indispensible due to the need of health issues and its challenges imposed by society. These issues come forth in Higher Education Institutions in an attempt to devise ways to face these demands. The research aims to analyze the Pedagogical Project (PP) present in the Dentistry Graduation Course in the Federal University of Rio Grande do Norte in Brazil-(UFRN). This is done in coherence the Brazilian National Curricular Guidelines considering main competences established in the PP. This research was approved by the Ethics Committee at UFRN under document number 285/201. The work is of descriptive nature and was realized with 30 students in the Dentistry Graduation Course. Interviews were realized with the use of problem situation approach. The research was also supported by documental studies that dealt with syllabus present in the disciplines taught at UFRN. Data were processed with the use of the ALCESTE 4.9 software. It is possible to acknowledge that some conservative conceptions arise, even though there is use of active methodologies and innovation that aim to promote reflection and articulation for general competence development such as proposed in the Pedagogical Project in Dentistry Graduation Course at UFRN. These conceptions are mainly present in the teaching-learning process where students do not have full participation. Thus it is possible to conclude that even though there are advances and breakthroughs. This is seen with that fact that there was inclusion of multidisciplinary clinical work as well optional courses in the curriculum. It was also seen that there was occasional use of active teaching methodologies in Dentistry at UFRN. But there is still a need for a didactical and methodological resizing. These actions require the need for progressive development of competences and abilities during the formative process according to what was established in the Brazilian National Curricular Guidelines

The need for universal access to health and the failure of the pedagogical model centered on the transmission of knowledge has led to changes in the training of health professionals. The objective of this study was to provide a new alternative for evaluating dental students through the development, validation and application of evaluation criteria based on the National Curriculum Guidelines (DCN in Brazil). Therefore, the study was conducted in three phases: development and validation of evaluation criteria of Dentistry courses based on the DCN; a pilot study to verify the applicability of the validated criteria and evaluation of the dentistry courses in the Northeast. In the first stage, a logical model was formulated, allowing for the construction of a criteria matrix, validated by a modified Delphi consensus technique. The validated matrix has the following dimensions: Profile of graduates, health care guidance, teaching and service integration, and pedagogical approach. The pilot study was conducted in five dental courses through a documentary study of the pedagogical project course (PPC), and application of validated questionnaires and interviews with course coordinators. The results of the pilot study indicate the possibility of being verified by means of validated criteria and using different methodological proposals, advances and curricular limitations facing the proposed reorientation of training recommended by DCN. The evaluation of Northeast Dentistry courses was carried out by applying a questionnaire validating a matrix of 30 course coordinators, including public and private institutions. The data were submitted to descriptive analysis, and also tested the difference between means and the correlation between the assessment of the coordinators in the dimensions and sub-dimensions with each other, among the general evaluation of courses and between the following variables: administrative category, time since last curriculum updating, participation in reorienting the training of health professionals programs, ENADE and CPC (Preliminary Concepts of the Course) scores in the year 2013. Positive correlation (p <0.01) was found between the means obtained by the perception of the coordinators in most dimensions, and also between them and the overall performance of the course. There were no significant differences between the coordinators’ perception about course performance and the administrative category (public / private). This difference is slightly higher when the average performance is compared with respect to time due to the last curriculum update, getting better performance in courses with the latest updated curriculum, even with there not 11 being this significant difference between dimensions. Better averages of performance were obtained in courses that do not participate in reorientation programs of professional training, with a significant difference (p<0.05) for the overall score and for all dimensions except the dimensions of teaching-service Integration (p = 0.064). There was no significant correlation between the assessment of coordinators in all dimensions, in the overall assessment or ENADE and CPC scores in 2013. The final instrument proposed in this study is a different alternative assessment for health training of both dentists and other professionals, considering that the DCN providing for the training and graduation of professionals is focused on the health needs of the population, integrated with the SUS (the National Brazilian Health System) and based on student-centered learning.

This thesis proposes environmental education as a strategy for the inclusion of sustainability in the academic education of higher level. The dentistry course has been the object of study, which is justified by the recognition of the need for reflection on environmental issues in the dental academia, initially based on professional experience of the author as a dental surgeon. The aim of this study is to investigate the scientific production of dentistry and its content related to environmental issues, in addition to expanding discussions and reflections on the need to insert environmental education as academic content. With the specific purpose of verifying the amount and analyze the content of scientific articles involving issues related to sustainability in dentistry, Chapter 01 presents research in leading journals portals available on the internet. Works were surveyed where sustainability and related issues were present and placed in a theoretical framework that analyzes the dental service inclusion in the dominant economic model. These procedures are intended to prove the hypothesis that the dental profession does not produce significant scientific content that relates the profession to the environment and sustainability. A literature review was conducted with the statement of dentistry changes from its origins to the front position to the dominant development model and exemplification of the deleterious effects of this model on the environment. In addition, there was a scientific research in journals portals available on the internet and investigated the amount and content of scientific articles involving issues related to sustainability in dentistry. Chapter 02 has the specific purpose of providing content to expand discussions and reflections on the need to insert environmental education in undergraduate courses in dentistry, such as insertion strategy into a new development model guided by sustainability. In this, students questionnaires were given the 8th dentistry course of the period the Federal University of Rio Grande do Norte (UFRN), to be understood environmental perception of learners and were obtained grants for proof of the thesis that environmental education applied dentistry has the potential to make people aware and willing to act practicing and propagating sustainability in their conduct. The overall results indicate little scientific production, as the research and work that relates to dentistry to sustainability and the issues related to the environment have not significantly been present in the syllabus of the undergraduate courses in dentistry, despite the interest shown by survey respondents When such issues are addressed. In this context, it is proposed fostering actions to environmental education, so that dental professionals are engaged in the construction of a new development model based on sustainability, as despite the environmental theme seems to be little explored in the academic and scientific world of dentistry, there interest from students and great potential multiplier for appropriate environmental behavior. After proving the hypothesis that the environment-related content are poorly explored in the academic and scientific world of dentistry, the main conclusions were recognizing the importance of environmental education as an interdisciplinary tool for environmental thematic approach in undergraduate courses dentistry, in addition to implementing this new pedagogical proposal in the professional practice of dentists, given their potential multiplier for environmental knowledge.

Brazil has been undergoing major demographic change.According to IBGE, the next 20 years the country's elderly population may reach over 30 million people. This tariff provides specifics regarding the process of health / disease. It is essential that higher education institutions are committed to this demand in view of the integrated training of health needs of society. The aim of this study is to analyze the Pedagogical Political Projects (PPP) of courses in dentistry in Rio Grande do Norte (RN), according to the national curriculum guidelines (DCNS) and training from the perspective of health care for the elderly. This is an exploratory study with a qualitative approach: with records and interviews. The study subjects were an Assistant Professor in the development of PPPs for each institution. The scenario in this study were dental training institutions in the newborns. Initially, the analysis of the PPP was by using the Alceste 4.9 software. The interpretation of the contents of interviews with teachers was done through content analysis of Bardin (2010). The PPPs are based on the DCNS, meet the characteristics of regional and seek a generalist, but still strongly directed to technical and scientific aspects of professional practice. Efforts and institutional approaches, involving teachers and students of the courses are being mobilized for training with more articulated network of health services. However, the emphasis on content pertaining to the health care of the elderly, is still limited when compared to those targeted content inherent in children and adolescents in all three curricular structures. It is reasonable to conclude that the historical, political, scientific, cultural and social, present in society, influence the formation of the dental professional RN. The greater participation of society in the process of vocational training in dentistry is needed. This can be done from the involvement of universities with health councils, bodies representing the dental profession and other segments of civil society in order to induce changes that generate ideas and educational practices integrative and interdisciplinary, with emphasis on continuing education for teachers, servants, employees and students. Containing conduct this process inherent flexibility of curriculum, teaching-service integration and coordination abilities and professional skills that are essential to understanding the human being and its complexities

This qualitative study of descriptive and exploratory nature was conducted with the aim of evaluating the contribution of university extension towards the training and life histories of dentistry students, using the focus group technique. The material was assessed using the collective subject discourse analysis technique. The results showed the impact exerted by academic experience, in extension activities within the personal, professional and active citizenship spheres. The subjects' perceptions revealed an opportunity to develop and improve their professional skills, through recognition of distinct realities of life, through breaking away from the traditional model of teaching and through fruitful relationships between students, university and society. Feelings of satisfaction, personal fulfillment, recognition and being an active and critical citizen were reported. It was concluded that experience within the field of extension is an important agent for the individual and collective process of academic training.

The present research carried out from three national dentistry magazines published in the period between 1990 and 2004, has as a goal to analyze how bioethics has been approached in this area, not only identifying the main concerns and tendencies, but also aiming to learn how this knowledge is produced and divulged in the dentistry circuit. We have articulated a quantitative-qualitative approach, studying 2995 articles. The articles were selected and assorted in twenty thematic categories, through their titles and key words. The analysis of the empiric material shows that, although there is a growth tendency of this discussion, little has been published about this theme (1,9%). Besides, it seems that there is an arrhythmia between the present bioethic approach in dentistry and the present life demands, where the deontology and legalist focuses are predominant, seeming to correspond to the inner aspects of the profession alone. In spite of this, through the qualitative approach it was possible to identify ways to build a more complex and integral odontological formation and practice. Within the conclusions, we still point out, that, this investigation, even face to its limitations, seems to offer subsidies for reflection and further studies about the theme, working as a parameter to keep up with the evolution of the bioethic thinking in the Odontology

The aim of the present study was to point out the importance of the experience of undergraduate dental students in extra-curricular activities and volunteer work, as a means through which to gain essential knowledge and abilities for their professional lives. A literature review of the Medline, Scielo, and Lilacs databases was carried out in an attempt to select articles related to the university extension and volunteer work of undergraduate dental students. It is still extremely difficult to include university extension and volunteer work as an important activity in Dentistry courses. However, the presentday work market demands professionals who have expertise not only in dental techniques, but also in the socio-cultural characteristics of communities, considering that people need to be comprehensive in their psychosocial aspects in order to be treated as a complete professional. Therefore, university dentistry courses should give equal consideration to both oral rehabilitation skills and the promotion of general healthcare, acquired mainly through extracurricular activities, in an attempt to redeem the integral education of the healthcare professional. Moreover, students should pay closer attention to the opportunities offered during their undergraduate courses, as the work market for dentists is becoming more and more competitive. Moreover, the dentist whose professional life is limited to the dental office will most certainly forgo the opportunity to act in other social areas as well as the recognition that comes with such acts.

Os cursos de graduação em odontologia vêm privilegiando uma formação fundamentada na técnica, com práticas curativistas e individualizadas, tornando-se incapazes de formar a força de trabalho necessária à resolução dos problemas de saúde bucal da população. Com a implementação das Diretrizes Curriculares Nacionais (DCN) para os cursos de graduação em odontologia, uma série de mudanças curriculares vêm sendo executadas no sentido de favorecer a formação adequada. Acredita-se que a educação pela experiência configure-se como um conjunto de ferramentas viável e eficaz para garantir a formação adequada e coerente com os princípios do Sistema Único de Saúde (SUS). Cita-se, como uma dessas possibilidades, os Estágios Curriculares Supervisionados (ECS), previstos nas DCN para serem desenvolvidos de forma articulada e com complexidade crescente ao longo do processo de formação. O estudo destina-se a compreender a articulação ensino-trabalho-cidadania por diferentes olhares e, aliado a experiências vivenciais dessa articulação, construir um modelo de Estágio Curricular Supervisionado (ECS) em serviço público de saúde, no âmbito da Atenção Primária em Saúde (APS), para cursos de graduação em odontologia. Trata-se de um estudo qualitativo dividido em duas fases. Na primeira, foi experienciado um modelo de estágio vinculado à um projeto de pesquisa que se propõe à inovar as práticas de saúde bucal no SUS, utilizando-se de uma proposta de clínica ampliada. Nessa etapa, participaram a pesquisadora, estagiários e preceptores que foram entrevistados e/ou escreveram diários de campo. Na segunda fase, alunos de odontologia, profissionais e gestores de serviços de saúde do município de São Paulo manifestaram suas percepções por meio de grupos focais e entrevistas individuais, respectivamente. O material coletado foi analisado por intermédio da hermenêutica dialética e da triangulação de dados. Os dados descortinam a intimidade das clínicas de uma Faculdade de odontologia, revelando o que se denominou de ensino da odontologia \'in vitro\', distante da realidade e limitado no sentido de solucionar os problemas de saúde bucal do público atendido. Em contrapartida, foi evidente os benefícios que as vivências no mundo real, nos mais variados espaços, podem trazer para esses estudantes. Para os estagiários do modelo experienciado, a prática em clínica ampliada permite extrapolar a odontologia \'in vitro\' e se aproximar da realidade. Preceptores e gestores manifestam opiniões convergentes e explicitam, ainda, o poder transformador que a presença de estudantes denota para os serviços além de induzir à educação permanente dos profissionais que atuam como preceptores. Com bases nessas colocações, foi elaborado um modelo de ECS para cursos de odontologia, de modo a permitir que os estudantes experienciem a realidade de saúde e trabalhem na dimensão da clínica do corpo vivo, subjetivado e complexo. Deseja-se oferecer ao estudante a possibilidade de refletir e experienciar os espaços onde as ações em saúde são produzidas, em um processo de ensino-aprendizagem centrado metodologias ativas, com a mediação pedagógica desenvolvida por preceptores e docentes. Acredita-se que suas características, pensadas em função da triangulação dos diferentes olhares que compuseram o estudo, revertem-se de força suficiente para inquietar o instituído e metamorfosear a formação disfarçada da odontologia.

HENRIQUES, Regina Lúcia Monteiro.2011. 182 f. Tese (Doutorado em Saúde Coletiva) Instituto de Medicina Social, Universidade do Estado do Rio de Janeiro, Rio de Janeiro, 2011. Este estudo trata dos processos de mudança na formação em saúde, especialmente das questões político estruturais da articulação do ensino e da extensão para a construção de estratégias de transformação dos cursos da área da saúde. Tem por objetivos analisar as perspectiva dos sujeitos envolvidos na transformação curricular no que diz respeito à articulação entre práticas de ensino, extensão universitária e saúde, a constituição de novos cenários de prática e sua relação com a extensão universitária, assim como examinar os sentidos atribuídos pelos sujeitos aos processos políticos internos e externos às instituições de ensino. Parte-se da compreensão de que há em andamento um grande movimento de lutas pela mudança na formação em saúde e de algumas das ideias que têm sido discutidas e difundidas na defesa da reorientação da formação em saúde baseada em princípios e diretrizes consoantes com a política de saúde e com a defesa de direitos de cidadania. Baseia-se em concepções de espaço cotidiano das instituições de formação superior em saúde e dos serviços de saúde e outros cenários de prática. Reflete sobre a responsabilidade política das instituições formadoras e da extensão universitária como lugar de tornar públicas as posições e valores defendidos para as práticas do cuidado e da relação social e política da universidade. Para a operacionalização do estudo, foram escolhidas duas instituições universitárias que se apresentaram e que foram selecionadas no programa do Pro-Saúde. Foram realizadas entrevistas com roteiro semi-estruturado com protagonistas de processos de mudança na formação nestas instituições, em três profissões da área da saúde, enfermagem, medicina e odontologia. Fez-se analise hermenêutica a partir dos sentidos que foram atribuídos a estas experiências concretas pelos atores que as empreenderam. Definiu-se três categorias de análise, a dimensão das políticas governamentais de incentivo a mudanças na formação em saúde e os efeitos das mesmas para as instituições de ensino; a ampliação de cenários de prática, as estratégias de aproximação entre os mundos do ensino e do trabalho e se significaram novas práticas de cuidado; relação existente entre os processos de transformação curricular e a extensão universitária. A extensão vem adquirindo protagonismo na construção de dispositivos de enfrentamento e superação das dificuldades e resistências nos processos de transformação curricular, além de criar com relativa liberdade novas possibilidades espaciais e conceituais para o cuidado em saúde, porém pelos próprios sentidos que assume desde a invisibilidade até a redenção da universidade sua baixa institucionalidade e reflexão impede que sua potencialidade seja tomada como aliada nestes processos de modo mais sistemático e impactante.

Os orifícios de acesso aos parafusos de retenção devem ser preenchidos para que o parafuso não seja danificado caso seja necessária a remoção da prótese. Dentre os materiais mais utilizados estão o algodão, a fita de politetrafluoretileno e a guta percha. O objetivo deste estudo é avaliar a formação de biofilme de Candida albicans nos materiais anteriormente descritos, buscando estabelecer um parâmetro que contribua para a escolha do tipo de material mais adequado a ser utilizado clinicamente. Foram utilizados UCLAs, análogos e parafusos sextavados, todos de titânio. Os conjuntos foram montados com torque de 32N. Os materiais foram condensados no interior dos UCLAs e colocados em meio de cultura com uma suspensão de 3x106 células/ml de Candida albicans. O sistema foi armazenado à 37C com agitação, por 15 dias e o meio foi renovado a cada 48 horas. A quantificação de biofilme foi realizada pelo ensaio de MTT e leitura à 490nm, resultando em diferentes valores de densidade óptica. A normalidade (p=0,304 - Kolmogorov-Smirnov) e a igualdade de variâncias (p=0,721 - Scheffe) foram testadas primeiramente. O teste de análise de variância demonstrou diferença significativa entre os grupos (p<0,001) e com o Holm-Sidak foi observada diferença significativa entre os grupos algodão e guta (p<0,05) e algodão e fita de politetrafluoetileno (p<0,05); não houve diferença significativa entre os grupos guta e fita de politatrafluoretileno (p>0,05), apesar dos valores da fita de politetrafluoetileno terem sido maiores. Considerando-se as limitações deste estudo in vitro, podemos concluir que tanto a guta-percha quanto a fita de politetrafluoretileno apresentaram menor formação de biofilme, não havendo diferença estatisticamente significativa entre os materiais. O algodão apresentou um nível de formação de biofilme significativamente maior que a fita de politetrafluoretileno e a guta percha. Diante disso, serão necessários novos estudos para confirmar as limitações que este tipo de material pode apresentar quando usado como material de preenchimento do acesso do parafuso da prótese sobre implante.

Os debates sobre formação profissional em saúde ampliaram seu espaço na agenda de discussões políticas brasileiras. As Diretrizes Curriculares Nacionais para Cursos na Área de Saúde, homologadas pelo Ministério da Educação em 2001, orientam mudanças em graduação dos profissionais, coerentes com a necessidade indicada pelo Ministério da Saúde de incentivar mudanças na formação em saúde com ênfase na integralidade da atenção. Este trabalho investigou as propostas das novas Diretrizes Curriculares Nacionais para os cursos de odontologia (DCNO), tendo como eixo de análise o princípio da Integralidade em saúde e o trabalho em equipe. A partir do referencial teórico da construção da Integralidade em saúde, foi analisada a percepção de seus elementos no discurso de gestores acadêmicos, professores e alunos de um curso de odontologia e no documento das DCNO. A análise do documento das DCNO demonstrou uma reduzida sistematização das ideias e conceitos associados à integralidade em saúde, reforçando a ênfase nas práticas do Cirurgião-Dentista ao âmbito da Saúde Bucal. A análise das entrevistas revelou certo grau de apropriação, pelos autores estudados, de discursos que ampliam o universo da odontologia, porém referem-se a práticas profissionais e de ensino-aprendizagem ainda bastante calcadas no conhecimento clínico-cirúrgico aplicável ao indivíduo. Existe uma associação entre integralidade em saúde, perfil generalista e trabalho em equipe à integração das especialidades odontológicas, viabilizadas pela integração das clínicas. Nota-se uma tendência à mudança de valores, inclusive nos depoimentos de estudantes, que demonstram interesse nas práticas no setor público, reforçando a necessidade de ampliação da odontologia na arena de discussões sobre a formação em saúde, de modo a aproximar conteúdos e práticas de saúde coletiva com aquelas do campo clínico-cirúrgico sob novas perspectivas e aproximar a teoria da área específica de atuação, avançando na construção do trabalho em equipe.

O estudo aborda a gestão pública em Odontologia focalizando suas dificuldades e perspectivas. Tem por objetivo identificar e descrever a existência ou não de dificuldades e ainda as perspectivas para promover o exercício da referida gestão. Trata-se de uma investigação de caráter descritivo qualitativo. Contou com a colaboração de 10 participantes – gestores da odontologia – em exercício, em Porto Alegre e municípios vizinhos. Os dados foram coletados por meio de entrevistas. Foi utilizado como método de análise , a análise de conteúdo tipo temática que foi validada pela técnica da triangulação, própria para estudos qualitativos. O estudo conclui que as dificuldades dos gestores relacionam-se com os aspectos jurídico / administrativo, ideológico / conceitual e no tipo de prática de saúde do Sistema Único de Saúde. Os gestores são otimistas quanto as perspectivas do S.U.S. e há disposição para acertar e bem conduzir a função de gestor. A pesquisa revela a necessidade de oferecer capacitação ao recurso humano do setor público, em especial aos gestores. Neste sentido o “locus pedagógico” de sua formação é o próprio município.

Photodynamic therapy (PDT) has been proposed as an alternative method for the treatment of biofilm-dependent oral diseases like dental caries. This therapy consists of simultaneous action of a visible light (L) and a photosensitizer (FS) in the presence of oxygen, which leads to production of different reactive oxygen species that can interact with the bacterial cell components, and promote cell death. This study aims to evaluate the antimicrobial action of PDT on oral bacteria in suspension, as well as the formation of mono and multi-species biofilms, in vitro, from a standard strain of Streptococcus mutans (ATCC 25175) and saliva samples, respectively. The dye methylene blue (MB) and toluidine blue (TB) were used at a concentration of 100 mg/ L and activated by halogen light (600 to 750 nm) from a modified hand held photopolymerizer (Ultralux ®, Dabi Atlante, Ribeirão Preto , São Paulo, Brazil.). Planktonic cultures were prepared and submitted to different experimental conditions: 1. PDT using TB 2. PDT using MB, 3. L+ FS- , 4. TB + L - ; 5. MB+ L-; 6. L- FS- (negative control) and 7. administration of 0.12% chlorhexidine digluconate (positive control) (Periogard ®, Colgate-Palmolive Company, New York, USA). The immediate and mediated action of PDT on bacterial suspensions, as well as its effect on biofilm formation were observed from the number of colony-forming units per milliliter (CFU/mL) and measures optical density (OD). The data were statistically analyzed using the Kruskal-Wallis and Mann-Whitney test for the significance level of 5%. According to the results, the PDT showed no antibacterial action on suspensions of S. mutans, regardless of the dye used. PDT with MB activated by halogen light was able to reduce 86.6% CFU/mL multi-species planktonic cultures, however, this reduction was not significant (p > 0.05). PDT showed antibacterial effect, mediate on multi-species planktonic cultures with TB (p < 0.001) and MB (p < 0.001), activated by halogen light. PDT was able to prevent the formation of multispecies biofilm, through the activation of TB by halogen light (p = 0.01). We conclude that activation of the dye toluidine blue and methylene blue, by halogen light (PDT) showed antimicrobial activity, compared to multi-species planktonic cultures prepared from saliva samples
