ABSTRACT: When applied at growing phase, lighting program aims to obtain quails with body weight and physiological maturity suitable for the beginning of laying. This study evaluated lighting programs at growing phase on performance, sexual maturity and egg quality of meat quail breeders (Coturnixcoturnix) at laying phase. From 7 to 49 days of age, 300 female meat quails were subjected to three lighting programs (natural, intermittent and continuous), with 5 replicates of 20 birds each. At 49 days of age, 240 quails were transferred to a shed, maintaining the same experimental conditions. Meat quails submitted to continuous and intermittent lighting programs had higher weight of reproductive system and lower ages for first egg production and to reach 50% of egg production (P < 0.05). Quails submitted to natural lighting had lower feed intake from 49 to 70 and 71 to 92 days of age and worse feed conversion up to 114 days of age. Continuous and intermittent lighting programs resulted in more precocious quails compared to natural lighting program. Quails submitted to natural lighting at growing phase presented lower egg production during all periods, not differing for birds submitted to continuous and intermittent programs from the second period (71 to 92 days of age). Intermittent and continuous lighting result in better feed conversion of breeding quails up to 114 days and a higher percentage of laying (49 to 136 days), reducing the number of days to produce the first egg and to reach 50% of laying, in relation to natural lighting.

RESUMO: Quando aplicado na fase de crescimento, o programa de luz visa obter codornas com peso corporal e maturidade fisiológica adequados para o início da postura. Este estudo avaliou programas de iluminação na fase de crescimento sobre o desempenho, maturidade sexual e qualidade dos ovos de codornas de corte reprodutoras (Coturnix coturnix) na fase de postura. Durante o período de sete a 49 dias de idade, 300 codornas de corte fêmeas foram submetidas a três programas de iluminação (natural, intermitente e contínuo), com cinco repetições de 20 aves cada. Aos 49 dias de idade, 240 codornas foram transferidas para um galpão, mantendo a mesma distribuição experimental e submetidas às mesmas condições. As aves submetidas aos programas de iluminação contínuo e intermitente na fase de crescimento apresentaram maiores peso relativo do sistema reprodutivo e consequentemente menores idades para produção do primeiro ovo e para atingir 50% da produção de ovos (P < 0.05). As aves que receberam apenas iluminação natural apresentaram menor consumo de ração nos períodos de 49 a 70 e 71 a 92 dias de idade e pior conversão alimentar até 114 dias de idade. Os programas de iluminação contínua e intermitente na fase de crescimento resultaram em codornas mais precoces quando comparados as aves submetidas ao programa de iluminação natural. Codornas submetidas a programa de luz natural na fase de crescimento apresentaram menor produção de ovos durante todos os períodos, não diferindo das aves submetidas a programas contínuos e intermitentes a partir do segundo período (71 a 92 dias de idade). A iluminação intermitente e contínua na fase de crescimento resulta em melhor conversão alimentar de codornas reprodutoras até 114 dias e maior percentual de postura (49 a 136 dias), reduzindo o número de dias para produzir o primeiro ovo e atingir 50% de postura, em relação a iluminação natural..

ABSTRACT BACKGROUND: Specific types of violence such as intimate partner sexual violence and intimate partner homicide occur more frequently in rural areas. OBJECTIVE: This study aimed to systematically review the literature on the knowledge and attitudes of rural healthcare providers regarding cases of domestic violence against women. DESIGN AND SETTING: Systematic review developed at Universidade Federal de Uberlândia. METHODS: We conducted an electronic search of six databases, which only included observational studies, regardless of the year, language, or country of publication, except for studies that used secondary data and were exclusively qualitative. Two reviewers performed the selection, data extraction, and risk of bias assessment using a specific Joanna Briggs Institute tool. RESULTS: Six studies met the inclusion criteria. All the studies had a low risk of bias. Approximately 38% of these professionals identified injuries caused by violence in patients. When asked about knowing the correct attitude to take in cases of confirmed violence, between 12% and 64% of rural healthcare providers answered positively; most of them would refer to specialized institutions and promote victim empowerment and counseling. The number of professionals with an educational background in the field ranged from 16% to 98%. CONCLUSIONS: The evident disparity across studies shows that some professionals have suboptimal knowledge and require training to adopt the correct attitude when identifying female victims of domestic violence in clinical practice. SYSTEMATIC REVIEW REGISTRATION: This systematic review was registered in the Open Science Framework Database under the registration http://doi.org/10.17605/OSF.IO/B7Q6S.

ABSTRACT The use of non-conventional feeds in poultry farming can reduce production costs, mainly because of its low cost, availability and chemical composition. Thus, parboiled whole rice bran (PWRB) appears as a potential use in feeding quails. Two experiments were carried out to evaluate the effects of the inclusion of PWRB in the diet of quails. In each experiment, a total of 288 seven-day-old European quails of both sexes, were distributed in a completely randomized design with six treatments and six replicates of eight quails each. The treatments consisted in the inclusion of PWRB in the proportions of 0; 5; 10; 15; 20 and 25% (first) and 0; 8; 16; 24; 32 and 40% (second). In the first experiment, a linear reduction in feed intake and weight gain was observed with the inclusion of PWRB above 5%, with no significant effect on feed conversion and carcass characteristics. However, there was no loss in the performance and carcass characteristics of quails fed with different levels of PWRB in comparison to the control group. In the second, it was observed that the inclusion of PWRB above 8% promoted a linear reduction in feed intake, weight gain and improvement in feed conversion, with no significant effect on carcass characteristics. However, quails fed 40% PWRB showed reduced intake and weight gain when compared to the control group. The use of PWRB provided an improvement in economic viability. Considering the effect on growth, PWRB can be used in the feeding of meat quails up to 32%.

RESUMO Objetivo. Investigar a carga de câncer de traqueia, brônquios e pulmão (TBP) decorrente da exposição ao tabaco nos últimos 30 anos em 12 países da América do Sul. Métodos. A função de exposição-resposta do estudo Carga Global de Doença (GBD, na sigla em inglês) 2019 foi usada para analisar o número de mortes e de anos de vida ajustados por incapacidade (AVAI) por câncer de TBP relacionado à exposição total ao tabaco e ao tabagismo e ao fumo passivo em 12 países da América do Sul entre 1990 e 2019. Os índices foram descritos em números absolutos ou taxas por 100 mil pessoas. A variação relativa da carga foi avaliada comparando-se os períodos de 1990 a 1994 e de 2015 a 2019. Resultados. Em 2019, os números de mortes e de AVAI por câncer de TBP associado à exposição ao tabaco na América do Sul, em todas as idades, foram, respectivamente, 29.348 e 658.204 em homens e 14.106 e 318.277 em mulheres. As taxas de mortalidade e os AVAI ajustados por idade na região foram, respectivamente, 182,8 e 4.035 em homens e 50,8 e 1.162 em mulheres em 2019. Em homens, 10 dos 12 países registraram uma diminuição relativa das taxas de mortalidade por câncer de TBP atribuído à exposição ao tabaco, mas somente 4 países obtiveram uma redução da mortalidade em mulheres. Conclusão. Apesar dos consideráveis esforços atuais para o controle do tabaco na América do Sul, ainda há uma expressiva carga de câncer de TBP na região, com disparidades significativas entre os sexos. É necessário dispor de mais dados primários sobre câncer de TBP e exposição ao tabaco específicos para cada país para aprimorar as estratégias de atenção à saúde e melhorar a compreensão das tendências regionais.

RESUMEN Objetivo. Investigar la carga del cáncer de tráquea, bronquios y pulmón por exposición al tabaco en los últimos 30 años en 12 países de Sudamérica. Métodos. Se utilizó la función de relación entre exposición y respuesta de la carga mundial de morbilidad del 2019 para analizar las muertes por cáncer de tráquea, bronquios y pulmón asociadas a la exposición total al tabaco, al tabaquismo activo y al tabaquismo pasivo, así como los años de vida ajustados en función de la discapacidad (AVAD), en 12 países de Sudamérica, entre 1990 y el 2019. Los resultados se presentaron en forma de número absoluto o de tasa por 100 000 personas. Se evaluó el cambio relativo de la carga mediante la comparación de los períodos 1990-1994 y 2015-2019. Resultados. En el 2019, el número de muertes por cáncer de tráquea, bronquios y pulmón y los AVAD asociados a la exposición al tabaco para todas las edades en Sudamérica fueron de 29 348 y 658 204 en los hombres y de 14 106 y 318 277 en las mujeres, respectivamente. La tasa de mortalidad y los AVAD ajustados por la edad correspondientes al 2019 en la región fueron de 182,8 y 4035 en los hombres y de 50,8 y 1162 en las mujeres, respectivamente. En el caso de los hombres, en 10 de los 12 países se observaron disminuciones relativas de la tasa de mortalidad por cáncer de tráquea, bronquios y pulmón atribuido a la exposición al tabaco, mientras que en el caso de las mujeres solo en 4 países hubo una reducción de la mortalidad. Conclusión. Aunque en Sudamérica se están llevando a cabo iniciativas importantes para el control del tabaco, en esta región persiste una carga considerable de cáncer de tráquea, bronquios y pulmón, con diferencias significativas en función del sexo. Es preciso contar con más datos primarios específicos de cada país sobre el cáncer de tráquea, bronquios y pulmón, así como sobre la exposición al tabaco, para optimizar las estrategias de atención de salud y mejorar la comprensión de las tendencias regionales.

ABSTRACT Objective. To investigate the burden of tracheal, bronchus, and lung (TBL) cancer due to tobacco exposure in the last 30 years in 12 South American countries. Methods. We used the Global Burden of Disease (GBD) 2019 exposure-response function to analyze the total tobacco, smoking, and secondhand smoke exposure-related TBL cancer deaths and disability-adjusted life years (DALYs), for 12 South American countries, between 1990 and 2019. Metrics were described as absolute numbers or rates per 100 000 individuals. The relative change in burden was assessed by comparing the 1990-1994 to 2015-2019 periods. Results. In 2019, the all-ages number of TBL cancer deaths and DALYs associated with tobacco exposure in South America was 29 348 and 658 204 in males and 14 106 and 318 277 in females, respectively. Age-adjusted death and DALYs rates for the region in 2019 were 182.8 and 4035 in males and 50.8 and 1162 in females, respectively. In males, 10/12 countries observed relative declines in TBL death rates attributed to tobacco exposure while only 4 countries reduced their mortality in females. Conclusion. While significant efforts on tobacco control are under place in South America, substantial burden of TBL cancer persists in the region with significant sex-specific disparities. Increased country-specific primary data on TBL cancer and tobacco exposure is needed to optimize healthcare strategies and improve comprehension of regional trends.

Resumo O objetivo do artigo é analisar a tendência da taxa de mortalidade padronizada (TMP) por tuberculose e sua correlação com o status de desenvolvimento no Brasil. Estudo ecológico de séries temporais que analisou dados de óbitos por tuberculose notificados entre 2005 e 2019 de todos os estados. Os dados foram extraídos do Sistema de Informação sobre Mortalidade, do Instituto Brasileiro de Geografia e Estatística e do estudo da Carga Global de Doenças. A tendência temporal foi analisada pela regressão de Prais-Winsten. A análise da correlação de Spearman entre a TMP e o índice sociodemográfico (socio-demographic index - SDI) também foi realizada. De 2005 a 2019, foram registrados 68.879 óbitos por tuberculose no Brasil. A taxa média de mortalidade foi de 2,3 óbitos por 100.000 habitantes. A tendência decrescente da TMP por tuberculose foi observada no Brasil e em todas as regiões. Verificou-se correlação negativa significativa entre o SDI e a TMP. A maioria dos estados apresentou tendência decrescente e nenhum deles teve tendência crescente. Uma relação inversa foi verificada entre o SDI e a mortalidade por tuberculose.

Abstract The scope of this article is to analyze the trend of the standardized mortality rate (SMR) for tuberculosis and its correlation with the developmental status in Brazil. An ecological time series study was conducted to analyze data of deaths from tuberculosis reported between 2005 and 2019 in all states. Data were extracted from the Mortality Information System, the Brazilian Institute of Geography and Statistics, and the Global Burden of Disease study. The temporal trend was analyzed using Prais-Winsten regression. Spearman’s correlation analysis between SMR and Socio-Demographic Index (SDI) was also performed. From 2005 to 2019, 68,879 deaths from tuberculosis were recorded in Brazil. The average mortality rate was 2.3 deaths per 100,000 inhabitants. The decreasing trend of SMR due to tuberculosis was observed in Brazil and in all regions. There was a significant negative correlation between SDI and TMP. TMP due to tuberculosis revealed a decreasing trend in Brazil and in all regions. Most states showed a decreasing trend and none of them had an increasing trend. An inverse relationship was found between developmental status and mortality due to tuberculosis.

Abstract This essay aims to critically analyze the recent field of studies known as Business and Human Rights, which addresses the negative impacts of human rights violations at the corporate level, covering theoretical discussions, principles, guidelines, standards, and regulations. We developed the essay focusing on three key topics: the business activities of transnational corporations negatively impact human rights all around the world; the initiatives created in order to address the impacts of business over human rights are discursive and, therefore, distant from the practices; companies and corporations make various attempts to abstain from their responsibility, even if they make symbolic and material reparations. For this, we illustrate the abstention from corporate responsibility through the human rights violations in the case of João Alberto de Freitas’ murder committed by Carrefour security guards in the parking lot of one of its stores in Porto Alegre, in 2020. Throughout the text, we argue that this field reveals the tensions between business and respect for human rights, understanding that this involves a minefield susceptible to being contested. Our contribution lies in indicating paths for the heavier involvement of researchers from the field of management with the real problems that challenge societies, such as human rights violations at the organizational level.

Resumo O objetivo deste ensaio é analisar, criticamente, o recente campo de estudos denominado Negócios e Direitos Humanos ( Business and Human Rights ), que aborda os impactos negativos das violações de direitos humanos no âmbito corporativo, abrigando discussões teóricas, princípios, diretrizes, normativas e regulamentações. Desenvolvemos o ensaio concentrando-nos em três temas centrais: as atividades de negócios das corporações transnacionais impactam negativamente os direitos humanos em todo o mundo; as iniciativas criadas no sentido de abordar o impacto dos negócios sobre os direitos humanos são discursivas e, portanto, distantes das práticas; empresas e corporações utilizam-se de várias tentativas para a abstenção da responsabilidade, ainda que façam reparações simbólicas e materiais. Para isso, ilustramos com a abstenção da responsabilidade corporativa pelas violações de direitos humanos no caso do assassinato de João Alberto de Freitas cometido por seguranças do Carrefour no estacionamento de uma de suas lojas em Porto Alegre, no ano de 2020. Ao longo do texto, argumentamos que este campo revela as tensões entre negócios e respeito aos direitos humanos, entendendo que se trata de um campo minado e passível de ser contestado. Nossa contribuição reside em apontar caminhos para um envolvimento mais potente dos pesquisadores do campo da gestão, com os problemas reais que desafiam as sociedades, como as violações de direitos humanos no âmbito das organizações.

Abstract Continuous development, improvement and innovation of ballistic material systems with superior energy absorption performance has been the subject of numerous works nowadays. Some research has been carried out with the objective of replacing traditional metallic and ceramic materials and composites with high-performance polymeric composites. Due to their excellent properties, multi-scale polymer composites have been used in the most varied segments of the industry, being recently researched in applications such as ballistic materials. This work promotes the combination of high-strength three-dimensional woven aramid fiber fabrics with vinyl ester resin to produce a panel through the compression molding process. The resin was reinforced with graphene nanoplatelets (0.1, 0.2 and 0.3% wt). The impact, tensile and flexural strength were evaluated, along with dynamic-mechanical analysis by DMA and by Hopkinson split bar test, indicating a trend of better performance for the composite containing 0.1% of graphene nanoplatelets.

Resumo A utilização de cimento pré-hidratado na formulação de argamassas e concretos é comum, pois nem sempre há um controle efetivo na produção do cimento, moagem, transporte e posterior armazenamento. Este trabalho apresenta um estudo de caso sobre a otimização de aditivo para uso com cimento pré-hidratado, avaliando as mudanças nas propriedades reológicas do cimento Portland pré-hidratado artificialmente. O cimento foi pré-hidratado artificialmente por exposição à umidade relativa (URs) de 90%, em ambiente de solução saturada de NH4Cl. Adicionalmente, as pastas de cimento foram avaliadas com e sem superplastificante. O teste de fluxo escalonado usando uma geometria de placas paralelas foi o método escolhido para avaliar o comportamento reológico, viscosidade aparente, tensão de escoamento e área de histerese de cada pasta em idade precoce. A reometria oscilatória foi realizada para avaliar o módulo de armazenamento (G'), comparando a consolidação com a cinética de hidratação obtida pela avaliação calorimétrica das mesmas suspensões. Os resultados iniciais do reômetro indicam que a amostra pré-hidratada apresenta menor nível de tensão de cisalhamento do que a amostra de referência, devido à maior reatividade da amostra não pré-hidratada.

Abstract The use of pre-hydrated cement in formulation of mortar and concrete is common because there is not always effective control on the cement production, grinding, transportation and subsequent storage. This paper presents a case study on the optimization of admixture for use with prehydrated cement by assessing changes in the rheological properties of Portland cement artificially pre-hydrated. The cement was artificially pre-hydrated by exposure to relative humidity (RHs) of 90%, in an environment of NH4Cl saturated solution. Additionally, the cement pastes were evaluated with and without superplasticizer. Stepped flow test using a parallel-plate geometry was the method choose to evaluate the rheological behavior, apparent viscosity, yield stress and hysteresis area of each paste at the early age. Oscillatory rheometry was conducted to evaluate the storage modulus (G’), comparing the consolidation with the hydration kinetics obtained by calorimetric evaluation of the same suspensions. Initial rheometer results indicate that the pre-hydrated sample presents lower level of shear stress than the reference sample, because of the higher reactivity of the non-pre-hydrated sample.

Abstract The cold roller die process increases the tensile strength and decreases the ductility of steel wire. Annealing heat treatment is applied to restore mechanical properties, but this is a costly process. This research shows that it is possible to control the mechanical properties of ultra-low carbon steel wire inducing the Bauschinger effect and relieving residual steel stresses. The present study uses several pulleys to promote and control the Bauschinger effect magnitude through alternated cyclic bending. A Completely Randomized Design, a regression study, and the Akaike Information Criterion were used to understand the relationship between the quantity and diameter of pulleys and the influence on the magnitude of the Bauschinger effect. Statistical models showed that it is possible to have a maximum increase of 103% in uniform elongation and a maximum decrease of 14% in yield strength. An interaction between the factors studied in controlling the Bauschinger effect magnitude was confirmed.

ABSTRACT The attempt to face the limitations of wood-based materials, especially concerning the relationship with water, is still a considerable gap in research on this subject. The present work proposes the accomplishment of thermal treatment in fiberboard-type hardboard, using different temperatures and times, to evaluate the effect on the physical-mechanical properties. The parameters of the heat treatment were temperatures of 120 and 160 °C and times of 20 and 40 min. The hardboards were individually heat treated in a kiln. The characterization was performed from physical tests such as bulk density, moisture content, water absorption (2 and 24 h), thickness swelling (2 and 24 h); and mechanical properties of flexural strength. The treatment with a temperature of 160 °C for 40 min showed the lowest values of water absorption in 24 h (34%). Thickness swelling was lower compared to control, for all the treatments applied. Regarding flexural strength, the treatment that adopted the 160 °C for 20 min showed the highest MOR value (26.3 MPa). In general, the performance of heat treatments positively influenced the physical and mechanical properties of the hardboards, being an interesting alternative in the development of products for applications in internal environments.

Self-inflicted lesions are examined from the perspective of psychoanalytic listening to fifteen adolescents who sought help at a walk-in clinic. Psychological suffering among contemporary adolescents often presents in the guise of this problem. Medicalization is critically assessed as the predominant response to such youths. Aided by psychoanalytic references, other modes of understanding the problem are explored, and Freudian theories of anxiety, pain, and symptom formation are deployed. Additionally, Lacanian theory is called upon to highlight the effects of the word and voice of the Other upon the adolescent subject. Two transgender youths presenting with histories of self-aggression lead to specific reflections on the issue.

Se investigan las autolesiones a partir de la escucha psicoanalítica de 15 jóvenes que fueron acudidos en ambulatorio público. El sufrimiento psíquico en la adolescencia contemporánea se presenta cada vez con mayor frecuencia en forma de este tipo de problemas. La medicalización, que ha sido una respuesta dominante para estos jóvenes, es evaluada críticamente. Con la ayuda del marco psicoanalítico, se exploran otras maneras de comprensión del problema, utilizando las teorías freudianas sobre la angustia, el dolor y la formación de síntomas. Con los aportes lacanianos, también se destacan los efectos de la palabra y la voz del Otro en el sujeto adolescente. Dos jóvenes transgénero que tenían un historial de autolesiones llevaron a reflexiones específicas sobre el tema.

Les automutilations sont étudiées à partir de l’écoute psychanalytique de 15 adolescents arrivés en centre ambulatoire. La souffrance psychique de l’adolescence contemporaine se manifeste de plus en plus fréquemment sous cette forme. La médicalisation, qui a été la solution majoritairement adoptée pour ces jeunes, est considérée sous un jour critique. Sont explorées, à l’aide du référentiel psychanalytique, d’autres formes de compréhension de cette problématique, grâce aux théories freudiennes sur l’angoisse, la douleur et la formation des symptômes. Faisant usage des apports lacaniens, sont également mis en relief les effets de la parole et de la voix de l’Autre sur le sujet adolescent. Deux jeunes transgenres présentant un historique d’automutilations ont conduit à des réflexions spécifiques sur le sujet.

A medicalização, que tem sido uma resposta dominante para esses jovens, é avaliada criticamente. Explora-se, com a ajuda do referencial psicanalítico, outros tipos de entendimento da questão, recorrendo-se às teorias freudianas sobre angústia, dor e formação de sintomas. Usando os aportes lacanianos, são destacados, também, os efeitos da palavra e da voz do Outro sobre o sujeito adolescente. Dois jovens transgêneros que apresentavam histórico de autoagressão conduziram a reflexões específicas sobre o tema.

ABSTRACT Objective: To evaluate the influence of non-invasive treatment associated with the use of infiltrating resin for managing caries lesions in primary teeth. Material and Methods: A systematic review was performed by selecting articles from 6 online databases, using a search algorithm and eligibility criteria for data extraction and data synthesis for the papers included. Clinical trials involving primary teeth with incipient caries lesions (1/2 of the enamel or 1/3 of the outer dentin) were included, presenting full text and answering the study's guiding question. This study used the RoB 2 tool for the risk of bias assessment and GRADE for certainty of evidence. Random effects meta-analyses were implemented, and lesion progression treatment effects were estimated through relative risk (RR) and associated 95% confidence intervals. Results: A total of 440 studies were found. After analyzing the inclusion criteria and removal of duplicates, eight studies were analyzed for quality evidence. Five of the eight studies included in this review contributed to the meta-analysis, all with some reflections regarding the risk of bias. Overall, the results of the meta-analysis showed that non-invasive treatment, when associated with the use of infiltrating resins, significantly reduced the risk of caries progression in relation to the treatment without this addition for follow-up periods ranging from 12 months to 2 years (RR 0.51 [0.40-0.65]). Conclusion: There is moderate certainty of evidence that the use of infiltrating resins associated with non-invasive treatments decreases the risk of caries progression in primary teeth with incipient caries lesions (1/2 of the enamel or 1/3 of the dentin outer) when combined with non-invasive control methods alone.

ABSTRACT. The objective was to evaluate the quality of Japanese quail eggs stored at room temperature (26.8ºC) and under refrigeration (10.9ºC), for different storage periods (0; 5; 10; 15; 20; 25 and 30 days). A total of 196 quail eggs were assigned to different treatments in a factorial arrangement of 2 (temperatures) x 7 (storage periods), with 3 replications and 4 eggs per experimental unit. Data were subjected to regression analysis of parameters as a function of storage time at room temperature and under refrigeration. There was a reduction in egg weight, albumen weight and height, yolk height and egg yolk index with increasing storage period as a function of temperatures (p < 0.05). Eggs at room temperature showed a reduction in albumen index, while eggs under refrigeration showed a quadratic behavior (p < 0.05). Storage days promoted a quadratic response in albumen and yolk pH (p < 0.05) of eggs at room temperature. Eggs at room temperature floated from the 15th day of storage. When stored at room temperature, quail eggs show a sharp decrease in internal quality during storage for up to 30 days. Refrigerated storage is recommended.

Resumo Introdução A fluoretação das águas de abastecimento tem sido apontada em estudos nacionais e internacionais como a mais eficiente e equânime forma de acesso a fluoretos na prevenção da cárie dentária. Objetivo Relatar os resultados do heterocontrole nas águas de abastecimento público do município de Colombo/PR, no período de dezembro de 2013 a novembro de 2014. Método Foram coletadas amostras mensais em 15 Unidades Básicas de Saúde, em dias da semana aleatórios, no período de 12/2013 a 11/2014. As amostras foram analisadas pelo método eletrométrico na Faculdade de Odontologia da Universidade Federal Fluminense. Resultados Foram analisadas 180 amostras, que variaram de <0,001 a 1,480 mg/L (média 0,715±0,232 mg/L). De acordo com o critério estabelecido pelo Centro Colaborador do Ministério da Saúde em Vigilância da Saúde Bucal, 51,11% das amostras apresentavam níveis de fluoretos adequados, 13,34% concentrações de flúor acima do ideal, e 35,56% abaixo do ideal. Conclusão O heterocontrole representa uma das principais estratégias de vigilância em saúde bucal, e, dessa forma, deve ser implementado e efetuado em todas as regiões que utilizam água fluoretada, a fim de garantir a manutenção de níveis ótimos de fluoretos.

Abstract Background The fluoridation of water supply has been pointed out in national and international studies as the most efficient and equal way of accessing fluorides in the prevention of dental caries. Objective To report the results of heterocontrol in public water supply in the municipality of Colombo/PR, from December 2013 to November 2014. Method The samples were monthly collected in 15 Basic Health Units, on random days of the week, from 12/2013 to 11/2014. The samples were analyzed by the electrometric method at the Faculty of Dentistry of Fluminense Federal University. Results 180 samples were analyzed, ranging from <0.001 to 1.480 mg/L (mean 0.715 ± 0.232 mg/L). According to the criteria established by the Collaborating Center of the Ministry of Health in Oral Health Surveillance, 51.11% of the samples had adequate fluoride levels, 13.34% above ideal fluoride levels, and 35.56% below ideal levels. Conclusion Heterocontrol could represent one of the main strategies of oral health surveillance, and, therefore, it should be implemented and carried out in all regions that use fluoridated water, in order to guarantee the maintenance of optimal fluoride levels.
