Abstract Objective: To analyze the existing state legislation, including not only the ordinary laws, but also their infralegal regulation and the state legislation on Hospital Dentistry. Material and Methods: A survey was carried out in the databases of the Legislative Assemblies of the Brazilian States and the Federal District, as well as the Regional and Federal Councils of Dentistry in Brazil. Subsequently, a survey was carried out in the databases of the Ministry of Health, State Dental Councils and Federal Dental Council in Brazil. Results: Only 8 Brazilian states have legislation in force regarding hospital dentistry, which represents 29.63% of the federative units. Among the Brazilian regions, the Midwest presented the highest prevalence of the laws found (37.50%), followed by the North (25%) and the other regions with the same coverage (12.50%). Also, an orientation and an ordinance from the Ministry of Health, six resolutions from the Federal Council of Dentistry, and a technical note from the National Health Surveillance Agency were found. Conclusion: Several States do not have rules on the subject, making it imperative to create a federal rule that not only imposes the presence of the dentist, but also regulates the proportion of the team, workload, and availability.

RESUMO A Conferência Internacional sobre Atenção Primária de Saúde, realizada em Alma Ata, foi um dos eventos mais significativos para saúde pública a nível mundial, onde pela primeira vez se pontuou a dependência entre pobreza e estado de saúde. Mesmo após 40 anos de sua realização, continua influenciando e direcionando políticas públicas que vão evoluindo sem abandonar os princípios da atenção primária. O objetivo do presente trabalho foi realizar uma revisão de literatura pautada no PubMed/Medline, Biblioteca Virtual em Saúde (BVS / Bireme / OMS-OPAS) e em documentos institucionais do Ministério da Saúde do Brasil, com o intuito de pontuar os reflexos dos preceitos da Conferência de Alma Ata nas políticas públicas brasileiras, traçando um perfil evolutivo até a estratégia saúde da família e suas perspectivas futuras. O estudo constatou forte influência dos preceitos da Conferência da Alma Ata nas políticas públicas de saúde brasileira, mas que ainda necessitam de aprimoramento para alcançar as metas e objetivos globais traçados pela Alma Ata e repactuados na Agenda de Sustentabilidade para 2030 da Organização Mundial da Saúde.

ABSTRACT The International Conference on Primary Health Care, held in Alma Ata, was one of the most significant public health events in the world, where for the first time the dependency between poverty and health status was discussed and measured. Even after 40 years of its implementation, it continues to influence directly public policies related to the principles of primary care. The aim of the present study was to carry out a review of literature based on PubMed / Medline, Virtual Health Library (BVS / Bireme / WHO-PAHO) and institutional documents of Brazilian Ministry of Health, in order to point out reflections of perceptions about Alma Ata Conference, in Brazilian public policies, tracing an evolutionary profile to the family health strategy and its future perspectives. Although the study found a strong influence of the Alma Ata Conference in Brazilian public health policies it still needs improvement to reach the global goals and objectives agreed by all countries in Alma Ata and reaffirmed in the World Health Organization’s 2030 Sustainability Agenda.

Abstract Objective This in vitro study evaluated the effect of commercial whitening dentifrices on erosive tooth wear (ETW) of bovine enamel samples, in comparison with commercial regular dentifrices. Methodology Sixty bovine crowns were embedded in acrylic resin, polished and then had their baseline profile determined. They were randomly assigned to 5 groups (n=12/group), according to the type of commercial dentifrice to be tested: GI – Crest Anti-cavity Regular; GII – Crest 3D White; GIII – Colgate Total 12 Clean Mint; GIV – Colgate Optic White; GV – Placebo (negative control, fluoride-free dentifrice). The samples were submitted to daily erosive and abrasive challenges for 3 days. The erosive challenges were performed 3 times a day by immersing the specimens in 0.1% citric acid solution (pH 2.5) for 90 s. Each day after the first and last erosive challenges, the specimens were subjected to the abrasive challenge for 15 s, using a toothbrushing machine (Biopdi, São Carlos, SP, Brazil), soft toothbrushes and slurry (1:3 g/ml) of the tested toothpastes (1.5 N). The specimens were kept in artificial saliva between the challenges. The final profile was obtained and the ETW (µm) was calculated. Data were analyzed by Kruskal-Wallis and Dunn’s tests (p<0.05). Results All dentifrices tested significantly reduced the enamel wear in comparison with the Placebo, except GIII. The median (95% CI) ETW was 1.35 (1.25-1.46)bc for GI, 1.17 (1.01-1.34)cd for GII, 1.36 (1.28-1.45)ab for GIII, 1.08 (1.04-1.14)d for GIV and 2.28 (2.18-2.39)a for GV. Conclusion When dentifrices from the same manufacturer were compared, the whitening dentifrices led to similar or less wear than the regular ones.

RESUMO Este estudo teve como objetivo apresentar um panorama do ensino de cariologia nos cursos de graduação em Odontologia no Brasil. A coleta de dados foi realizada por meio de uma versão em Português Brasileiro de um questionário de 12 itens (Schulte et al., 2011) que foi enviado a todas as faculdades de Odontologia brasileiras (n = 219). A taxa de resposta foi de 57,0% (n = 125). Dentre as faculdades que responderam o questionário, 84,8% apoiam o desenvolvimento de um currículo brasileiro de cariologia. As disciplinas responsáveis por lecionar os conteúdos de cariologia são principalmente dentística (49,6%), odontopediatria (49,6%), saúde bucal coletiva (44,8%), e cariologia (32%). O ensino teórico de cariologia (74,4%) e os exercícios de pré-clínica (63,2%) são abordados principalmente durante o segundo ano do curso, enquanto as atividades clínicas ocorrem, em geral, no terceiro (71,2%) e quarto (64,8%) anos. Dentre os respondentes, 76,8% das faculdades incluem erosão dentária e 86,4% incluem defeitos dos tecidos dentários duros, como abrasão, no ensino da cariologia. Essa pesquisa foi capaz de determinar o panorama do ensino da cariologia no Brasil e detectar algumas diferenças de currículo entre as regiões do país. A promoção de um workshop para discutir os assuntos que devem ser ministrados aos estudantes de graduação em Odontologia e para desenvolver um currículo brasileiro de cariologia seria válida para reduzir as diferenças no ensino de cariologia no Brasil.

ABSTRACT This study sought to provide an overview of current cariology education for undergraduate Brazilian dental students. Data collection was via a Portuguese version of a 12-item questionnaire (Schulte et al., 2011) that was sent to all Brazilian dental schools (n = 219). The response rate was 57.0% (n = 125). Of the schools that returned the questionnaire, 84.8% supported the development of a Brazilian cariology curriculum. The units responsible for teaching cariology were predominantly operative dentistry (49.6%), pediatric dentistry (49.6%), dental public health (44.8%), and cariology (32%). Theoretical teaching of cariology (74.4%) and pre-clinical exercises (63.2%) were cited to occur mainly during the second year of the course, while clinical activities were placed in the third (71.2%) and fourth (64.8%) years. Among respondents, 76.8% of the schools included dental erosion and 86.4% included defects of dental hard tissues, such as abrasion, in teaching cariology. This survey was able to determine the panorama of cariology education in Brazil and to detect some differences among Brazilian geographic areas. The promotion of a workshop to discuss the topics that should be taught to undergraduate dental students and the development of a Brazilian core curriculum in cariology would be likely to reduce the differences in teaching cariology in Brazil.

Fluoridation of the public water supplies is recognized as among the top ten public health achievements of the twentieth century. However, the positive aspects of this measure depend on the maintenance of fluoride concentrations within adequate levels. Objective To report the results of seven years of external control of the fluoride (F) concentrations in the public water supply in Bauru, SP, Brazil in an attempt to verify, on the basis of risk/benefit balance, whether the levels are appropriate. Material and Methods From March 2004 to February 2011, 60 samples were collected every month from the 19 supply sectors of the city, totaling 4,641 samples. F concentrations in water samples were determined in duplicate, using an ion-specific electrode (Orion 9609) coupled to a potentiometer after buffering with TISAB II. After the analysis, the samples were classified according to the best risk-benefit adjustment. Results Means (±standard deviation) of F concentrations ranged between 0.73±0.06 and 0.81±0.10 mg/L for the different sectors during the seven years. The individual values ranged between 0.03 and 2.63 mg/L. The percentages of the samples considered “low risk” for dental fluorosis development and of “maximum benefit” for dental caries prevention (0.55-0.84 mg F/L) in the first, second, third, fourth, fifth, sixth, and seventh years of the study were 82.0, 58.5, 37.4, 61.0, 89.9, 77.3, and 72.4%, respectively, and 69.0% for the entire period. Conclusions Fluctuations of F levels were found in the public water supply in Bauru during the seven years of evaluation. These results suggest that external monitoring of water fluoridation by an independent assessor should be implemented in cities where there is adjusted fluoridation. This measure should be continued in order to verify that fluoride levels are suitable and, if not, to provide support for the appropriate adjustments.
