The results indicate that tooth loss and edentulism were complex phenomena, with intricate predisposing, demographic, enabling and need factors playing a role.

EXECUTIVE SUMMARYOral health is an essential component of good health, and good oral health is a fundamental human right. The role of the dental profession is to help the population and decision makers to achieve health through 278

Brazil is the only country in the world to propose a universal health care system with the aim of guaranteeing delivery of all levels of health care, free of charge, to a population of over 200 million inhabitants by means of a unified health system ("Sistema Único de Saúde" [SUS]). The national policy of oral health, also known as Smiling Brazil ("Brasil Sorridente"), was implemented in 2004. Oral health was designated as 1 of the 4 priority areas of the SUS, transforming oral health care in Brazil, with the objective that the SUS achieve the integrality of care envisaged at its creation. The aim of this article is to share part of this experience in order to prompt reflection about the inclusion of oral health care in other health care systems around the world. The most significant results of Smiling Brazil can be seen in 3 areas: (1) oral health epidemiological indicators, (2) financial investment and professional development, and (3) the building of an oral health care network throughout the 10 y of the policy. The "Discovery!" article presented here portrays 10 y of evolution; however, it is important to point out that this is a process undergoing construction and that the oral health care network needs to be further expanded, refined, and solidified so that over time and through changes in the political parties in power, Smiling Brazil prevails as a perennial policy and not merely an action by a single government.

This comprehensive critical review, carried out in a descriptive-discursive style, presents the oral health surveillance policy currently in force in Brazil. Based on an appraisal of the national and international literature on the subject of health surveillance, it examines the formulation of a scientifi c and political agenda for oral health surveillance, which is anchored in the institutions of the Brazilian Public Health System. The accomplishment of this agenda is exemplifi ed by the presentation of the most recent Brazilian Oral Health survey (SBBrasil 2010). A conclusive summary is presented on the search for a theoretical and methodological convergence of both the identifi cation of the obstacles and weaknesses still detectable in this policy, and the recognition of its virtues already confi rmed by important advances and achievements.

This article discusses the model of oral health care implemented in the Unified Health System of Brazil in the last decade. This model was conceived as a sub-sector policy that, over the years, has sought to improve the quality of life of the Brazilian population. Through a chronological line, the study presents the National Policy on Oral Health as a counter-hegemonic patient care model for the dentistry practices existing in the country before this policy was implemented. The reorganization of the levels of oral health care, the creation of reference facilities for secondary and tertiary care, through Centers of Dental Specialties and Regional Dental Prosthesis Laboratories, and the differential funding and decentralized management of financial resources were able to expand the actions of oral health for more than 90 million inhabitants. The evolution shown after the deployment of the National Oral Health Policy, as of 2004, demonstrates the greater integration of oral health care under the Unified Health System and provides feedback information to help this policy to continue to be prioritized by the Federal Government and receive more support from the state and local levels in the coming years.

Resumo O objetivo desse estudo foi analisar, por meio de uma revisão integrativa da literatura, os possíveis impactos das crises financeiras sobre os indicadores de saúde bucal em diferentes países, bem como verificar as medidas adotadas de forma a traçar um paralelo com a realidade brasileira. Uma busca de artigos que atendessem a estes critérios foi realizada nas bases PUBMED, EMBASE, Lilacs, SCOPUS e também na literatura cinzenta. Ao final, nove estudos foram incluídos. Os resultados indicam que a população em maior vulnerabilidade, menor renda e menor escolaridade são as mais afetadas, independentemente do indicador avaliado (cárie dentária não tratada, acesso aos serviços de Atenção Odontológica e hábitos de higiene). Quando medidas protetivas com alocação de recursos financeiras foram tomadas, as disparidades diminuíram. Concluiu-se que, frente às crises econômicas, a saúde bucal passa a não ser prioridade enquanto centro nucleador de políticas, o que impacta o acesso ao cuidado dos estratos sociais menos favorecidos.

This article aims at: i) describing and analyzing the expansion of dental care in the Unified Health System (SUS); ii) Identifying and analyzing the characteristics of hiring dentists' in the public service; iii) characterizing public vacancies, their duties and remuneration. In this descriptive case study, databases of the Ministry of Health were consulted and public tender notices. The findings indicate that 48% of the dentists enrolled in the National Registry of Health Establishments (CNES) perform care in the SUS, in 13 years there was an increase of 118% of the municipalities with oral health teams (eSB) implanted. The population coverage estimated by eSB increased by 10.46% between the years 2007 and 2015. The main mechanism for joining the Dental Specialties Centers (CEO) was the public tender. Primary care salaries ranged from 1. 05 to 12.67 Brazilian minimum wages, and to CEOs from 3.35 to 7.05. It is concluded that, among other measures, the planning of HRH strategies is necessary. The continuity of successes regulatory measures of labor contracts and support to local managers enter the agenda of priority actions of oral health policy.

A social movement to reduce caries prevalence in the world * D espite the fact that it is preventable, dental caries remains a global public health problem-even with fluoride intervention-and it is the most common chronic disease on the planet. Moreover, researchers have already shown for some years that caries is a disease continuum that at the early stages is reversible, yet many Ministries of Health and dental professionals misunderstand this. We believe it's important to address these issues and to drive broader understanding and action. As such, a public health program, the Alliance for a Cavity-Free Future (http://www.allianceforacavityfreefuture.org/en/us/aboutus), was developed. In the history of dentistry we have never yet had effective engagement between healthcare professionals, the government and other stakeholders to contain this widespread problem of dental caries in the world. The Alliance is a social movement, which convenes a worldwide group of experts who have joined together to work towards the goal of a Cavity-Free Future for all age groups. It acknowledges the global problem of caries, promotes an understanding of caries as a disease continuum, which is reversible, and will drive action to move communities and individuals to make the changes necessary to achieve the goal of a Cavity-Free Future. Overall, the group believes that global collaborative action is needed to challenge global leaders and other regional and local stakeholders to learn the importance of caries as a disease continuum and to participate in action toward the delivery of comprehensive caries prevention and management that can positively influence the continuing problem of caries. At the global level, the Alliance was launched on September 3, 2011 at the FDI World Dental Federation Congress in Salvador, Brazil. Since then the Expert Panel and Co-directors have been working hard to develop this initiative and have already received a tremendous amount of positive feedback from the global dental and public health community. The Alliance has identified the following long-term goals:
