RESUMO
OBJECTIVE: To analyze the factors associated with the proportion of abnormal results in screening mammograms. METHODS: Ecological study, with data from DATASUS/SISCAN, Atlas Brasil do Desenvolvimento Humano, Fundação SEADE, and Sistema e-Gestor, from 2016 to 2019, of women aged 50 to 69 years in the 645 municipalities of São Paulo (Brazil). Independent variables were associated with the outcome: proportion of unsatisfactory coverage of abnormal test results (Breast Imaging Reporting and Data System - BI-RADS® 0, 4 and 5 proportion >10% of tests performed). Multiple Poisson regression was used. RESULTS: Higher proportion of screening mammography (PR=1.20; 95%CI: 1.00;1.45), higher percentage of poor (PR=1.20; 95%CI: 1.07;1.36), low (PR=1.57; 95%CI: 1.38;1.78) and medium coverage of the Family Health Strategy (ESF) (PR=1.30; 95%CI: 1.09;1.52) were associated to the outcome. CONCLUSION: Socioeconomic and FHS coverage factors mediate the proportion of mammograms with abnormal results in public health services. Therefore, they are important aspects in the fight against breast cancer.

Este estudo teve como objetivo sistematizar os resultados das pesquisas que investigaram a relação entre a prática de TC e a saúde de indivíduos com Hipertensão Arterial Sistêmica (HAS) e Diabetes Mellitus (DM). Realizou-se uma revisão integrativa da literatura e foram realizadas buscas nas bases de dados PubMed, SciELO, LILACS e BVS. Foram incluídos estudos publicados nos últimos 20 anos em inglês, português e espanhol, que discorreram sobre a temática da prática de TC em indivíduos com HAS e DM. Foram excluídos estudos que não atenderam a temática proposta, não disponíveis na íntegra, duplicatas, revisões, anais de congresso, literatura cinzenta e livros. Foram identificados 21 estudos, com delineamentos diversos, realizados em sua maioria na China (n=12), que demonstraram o impacto positivo do engajamento na prática de TC na saúde de indivíduos com HAS e DM, como redução da pressão arterial, controle glicêmico e lipídico. Foram descritos também benefícios em outros aspectos físicos e psicossociais importantes para a manutenção do bem-estar e melhor qualidade de vida. Alguns estudos não descreveram resultados significantes associados à prática de TC . Em contrapartida, a maior parte dos estudos revisados relataram benefícios à saúde de indivíduos com HAS e DM associados à prática de Tai Chi.
This study aimed to systematize the results of research that investigated the relationship between the practice of TC and the health of individuals with Systemic Arterial Hypertension (SAH) and Diabetes Mellitus (DM). This is an integrative review in whicha search was conducted in the PubMed, SciELO, LILACS, and BVS databases. Studies published in the last 20 years, in English, Portuguese and Spanish, which discussed the theme of the practice of Tai Chi in individuals with SAH and DM, were included. Studies that did not meet the proposed theme, not available in full, duplicates, reviews, conference proceedings, gray literature and books were excluded. Twenty-one studies were identified, with different designs, carried out mostly in China (n=12), which demonstrated the positive impact of engaging in this bodily practice on the health of hypertensive and diabetic patients, such as blood pressure reduction, glycemic and lipid control. Benefits in other physical and psychosocial aspects that are important for the maintenance of well-being and better quality of life were also described. Some studies did not describe significant results associated with the practice of CT. In contrast, most of the studies reviewed reported health benefits for individuals with SAH and DM associated with the practice of Tai Chi.

Resumo O objetivo deste estudo foi analisar a literatura científica da área de saúde bucal coletiva quanto ao cálculo, apresentação e discussão do tamanho do efeito em estudos observacionais. A literatura cientifica na área (2015 a 2019) foi analisada quanto: a) informações gerais (periódico e diretrizes aos autores, número de variáveis e desfechos), b) objetivo e coerência com o cálculo amostral apresentado; c) tamanho do efeito (apresentação, medida utilizada e coerência com a discussão dos dados e conclusão). Foram analisados 123 artigos, de 66 periódicos. A maioria dos artigos avaliados apresenta um único desfecho (74%) e não menciona a realização de cálculo amostral (69,9%). Dentre os que realizaram, para 70,3% havia coerência entre o cálculo amostral utilizado e o objetivo. Apenas 3,3% dos artigos mencionam o termo tamanho do efeito e 24,4% não o consideram na discussão dos resultados, apesar de terem calculado. A regressão logística foi a metodologia estatística mais utilizada (98,4%) e o Odds Ratio a medida de tamanho do efeito mais utilizada (94,3%), embora não tenha sido citada e discutida como uma medida de tamanho do efeito na maioria dos estudos (96,7%). Os pesquisadores, em sua maioria, restringiram a discussão dos resultados apenas à significância estatística encontrada nas associações testadas.
Abstract The objective of this study was to analyze the scientific literature in public oral health regarding calculation, presentation, and discussion of the effect size in observational studies. The scientific literature (2015 to 2019) was analyzed regarding: a) general information (journal and guidelines to authors, number of variables and outcomes), b) objective and consistency with sample calculation presentation; c) effect size (presentation, measure used and consistency with data discussion and conclusion). A total of 123 articles from 66 journals were analyzed. Most articles analyzed presented a single outcome (74%) and did not mention sample size calculation (69.9%). Among those who did, 70.3% showed consistency between sample calculation used and the objective. Only 3.3% of articles mentioned the term effect size and 24.4% did not consider that in the discussion of results, despite showing effect size calculation. Logistic regression was the most commonly used statistical methodology (98.4%) and Odds Ratio was the most commonly used effect size measure (94.3%), although it was not cited and discussed as an effect size measure in most studies (96.7%). It could be concluded that most researchers restrict the discussion of their results only to the statistical significance found in associations under study.
RESUMO
Abstract This study aimed to make a longitudinal analysis of interexaminer calibration reproducibility in diagnosing dental caries in posterior teeth, by examiners without previous experience in epidemiological studies. A group of 11 inexperienced examiners underwent theoretical-practical training and calibration assessments, assisted by a standard examiner. An examiner who did not participate directly in the research selected 5-year-old children with and without caries. The D3 diagnostic threshold was used to evaluate dental caries, based on the World Health Organization (WHO) criteria. The initial calibration (baseline) was performed after the theoretical-practical training session, and consisted of examining 20 children; the second calibration occurred three months later, and involved evaluating another 18 children. The interexaminer agreement was obtained by kappa statistics, and by overall percentage agreement. The paired t-test was applied to compare the values for kappa means and overall percentage agreement between the time points studied. At baseline, the values for kappa (> 0.81) and overall percentage agreement (> 95.63%) were considered high. At the 3-month calibration assessment, all the examiners showed some decrease in both kappa (p < 0.0001) and overall percentage agreement (p = 0.0102). The calibration process currently proposed by the WHO is effective. However, reproducibility was not maintained over time for inexperienced examiners evaluating the posterior teeth of 5-year-old children, under epidemiological conditions.

RESUMO
This intervention follow-up study evaluated anxiety and stress levels and self-perceived happiness of individuals linked to the health field who did not practice Tai Chi and compared these variables before and after practicing this art. One hundred twenty-three participants were subdivided into two groups: G1) Older health professionals (n=41) and G2) Younger pre-university students interested in the health field (n=82). Participants received a 60-minute Tai Chi class. The Perceived Stress Scale (PSS-14) was applied before the practice, and the State-Trait Anxiety Inventory (STAI) and Andrews Face Scale were used before and after the class. Generalized linear models and the Bowker symmetry test were applied for data analysis. 46.3% and 30.5% of participants in G1 and G2 had mild stress levels, and 43.9% and 46.3% had moderate stress levels, respectively. After practicing Tai Chi, both groups presented significantly lower mean anxiety scores. In G1, 31.7% of participants went from moderate to mild anxiety levels after practice, 19.5% from severe to moderate, and 7.3% from severe to mild. In G2, 28.2% of participants went from moderate to mild anxiety levels after practice, 18.3% from severe to moderate, and 6.1% from severe to mild. Furthermore, 100.0% of individuals in G1 and 96.3% in G2 were happy after the class. Tai Chi was effective in reducing anxiety levels and improving self-perceived happiness.
RESUMO
Introduction: The purpose of this study was to evaluate the effectiveness and compare the accuracy of pulp tests in the diagnosis of teeth pulpal health. Material and Methods: Traumatized (n=71) and non-traumatized (n=71) teeth from 42 patients were evaluated. Each tooth underwent cold, heat, electric and oximetry tests, followed by radiographic examination and calculation of the sensitivity, specificity, PPV, NPV and accuracy. Results: Clinical and radiographic examination showed no alteration for the 71 teeth from the intact contralateral group. From the traumatized group, 29 teeth presented complete endodontic treatment, 17 presented periapical alterations that required endodontic treatment and 25 teeth did not present conclusive radiographic alteration. The cold test showed a significantly higher proportion of correct results, while the electric test showed a significantly lower proportion. The data showed higher accuracy for the cold, followed by oximeter and heat tests, while the electric test presented the lowest accuracy. Cold and oximeter tests proved superior over the electric and heat tests, while the electric test showed better parameters when diagnosing diseased pulp. Conclusion: Combining two pulp tests seems reasonable for improving the pulp diagnoses using both oximeter and cold or oximeter and heat tests to detect healthy pulp; or cold and electric tests to define diseased pulp.
Introducción: El propósito de este estudio fue evaluar la efectividad y comparar la precisión de las pruebas pulpares en el diagnóstico de la salud pulpar de los dientes. Material y Métodos: Se evaluaron dientes traumatizados (n=71) y no traumatizados (n=71) de 42 pacientes. Cada diente se sometió a pruebas de frío, calor, eléctricas y de oximetría, seguidas de examen radiográfico y cálculo de la sensibilidad, especificidad, VPP, VPN y precisión. Resultados: El examen clínico y radiográfico no mostró alteración en los 71 dientes del grupo contralateral intacto. Del grupo traumatizado, 29 dientes presentaron tratamiento endodóntico completo, 17 presentaron alteraciones peri-apicales que requirieron tratamiento endodóntico y 25 dientes no presentaron alteración radiográfica concluyente. La prueba en frío mostró una proporción significativamente mayor de resultados correctos, mientras que la prueba eléctrica mostró una proporción significativamente menor. Los datos mostraron mayor precisión para la prueba de frío, seguida de las pruebas de oxímetro y calor, mientras que la prueba eléctrica presentó la menor precisión. Las pruebas de frío y oxímetro demostraron ser superiores a las pruebas eléctricas y de calor, mientras que la prueba eléctrica mostró mejores parámetros al momento de diagnosticar pulpa enferma. Conclusión: La combinación de dos pruebas pulpares parece razonable para mejorar los diagnósticos pulpares utilizando tanto el oxímetro como las pruebas de frío u oxímetro y calor para detectar una pulpa sana; o pruebas de frío y eléctricas para definir pulpa enferma.

The study aimed to analyze the quality of life, oral health impact on daily activities and its association with adherence to dental treatment, and other factors, among vulnerable adolescents. It is a longitudinal analytical study performed with 15- to 19-year-old adolescents in the city of Piracicaba, São Paulo, from 2014 to 2015. The sample consisted of 476 adolescents referred for the treatment of caries and/or periodontal disease in family health units (initial phase). After 18 months, 325 individuals were assessed to investigate the dental treatment provided (final phase). The response variables considered in the final phase were the Quality of Life (WHOQOL-bref) and the Oral Impacts on Daily Performances (OIDP) questionnaires. The independent variables analyzed were sex, age, treatment adherence, and family cohesion and adaptability. A multiple regression model was used. The data on the physical (p<0.0001), social (p=0.0003), environmental (p<0.0001), and psychological (p<0.0001) domains of the WHOQOL collected in the initial phase had a positive relationship with the same domains assessed in the final phase. The WHOQOL data of the initial phase were associated with the WHOQOL data of the final phase (p=0.0341). The OIDP data of the initial phase were associated with the OIDP data of the final phase (p<0.0001). The OIDP of volunteers who did not adhere to dental treatment showed a higher impact (p=0.0234). The quality of life and impacts on daily performances of adolescents improved between the evaluation periods.

Abstract Bleaching gel thickeners induce important changes in tooth enamel and these changes are reversed by saliva. Objective This in situ study aimed to evaluate the effect of bleaching gels with different thickeners on tooth enamel under normal and hyposalivation conditions. Methodology Of 28 participants, 14 had normal salivary flow and 14 had low salivary flow. For each salivary flow, four types of treatment were performed with different thickeners: no bleaching (negative control), bleaching with a commercial 10% carbamide peroxide (CP) gel with carbopol (positive control) and bleaching with experimental 10% CP gels with natrosol and aristoflex. Participants used a palatal appliance containing bovine enamel/dentin specimens for 15 days. From day 2 to day 15, specimens were bleached extraorally. The bleaching gel was applied according to the groups for four hours. When the bleaching gel was removed, the palatal appliance was inserted again in the participants' mouth until the next day for another bleaching application. This procedure was repeated for 14 days and on day 15, surface microhardness (SMH), color (ΔE*ab and ΔE00), surface roughness (Ra), scanning electron microscopy (SEM), and energy-dispersive X-ray spectrometry (EDS) analyses were performed and data were subjected to statistical analysis. Results Neither salivary flow nor thickeners influenced ΔE*ab and ΔE00 results. Carbopol had the lowest SMH, the highest Ra, and the lowest Ca% among all groups. For normal flow, natrosol and aristoflex had higher SMH. For low flow, aristoflex had higher SMH and natrosol and aristoflex had lower Ra. Aristoflex had higher Ca% and Ca/P and differed from carbopol for normal flow. Conclusion For normal flow, 10% CP gels with natrosol and aristoflex caused fewer surface changes, and for low flow, only the 10% CP gel with aristoflex.
RESUMO
Resumo Introdução O conhecimento dos fatores relacionados à perda dentária contribui para o planejamento das ações preventivas realizadas pelas Equipes de Saúde Bucal (ESBs). Objetivo Avaliar o indicador de proporção de exodontia nos municípios do estado de São Paulo e a sua relação com os indicadores socioeconômicos e cobertura das ESBs. Método Estudo ecológico com dados secundários dos 645 municípios do estado de São Paulo do ano de 2012. A variável dependente foi o percentual de exodontia mensurado pelo indicador de proporção de exodontia em relação aos procedimentos individuais realizados pelas ESBs, disponibilizado pelo Sistema de Informação da Atenção Básica. Foram considerados como variáveis independentes a cobertura populacional estimada pelas ESBs, o Produto Interno Bruto (PIB) dos municípios per capita, o Índice de Desenvolvimento Humano (IDH) e o Índice Paulista de Responsabilidade Social (IPRS). Foram aplicados modelos lineares generalizados, avaliados pelo p-valor do teste de Wald, AICC e grau de liberdade. Resultados Apresentaram maior proporção de extrações dentárias as cidades do estado de São Paulo com menor cobertura de ESBs (p < 0,0001), com menor valor de IDH (p < 0,0001) e com maior valor de IPRS (p = 0,0018). Conclusão A baixa cobertura de ESBs e as desigualdades socioeconômicas contribuem para aumentar as extrações dentárias no estado de São Paulo.
Abstract Background Knowledge about factors associated with tooth loss contributes to the planning of preventive actions carried out by Oral Health Teams (OHT). Objective To evaluate the proportion of dental extraction indicator in the cities of the state of São Paulo, Brazil, and its relationship with socioeconomic indicators and coverage of the OHT. Method Ecological study using secondary data from 654 municipalities in the state of São Paulo conducted in 2012. The dependent variable was the percentage of dental extraction measured by the proportion of this indicator in relation to individual procedures performed by the OHT provided by the Primary Health Care (PHC) Information System. The population coverage by the OHT, the per capita Gross Domestic Product (GDP), the Human Development Index (HDI), and the São Paulo Social Responsibility Index (IPRS) of the municipalities were evaluated as independent variables. Generalized linear models, formulated by the Wald test p-value, Corrected Akaike Information Criterion (AICc), and degree of freedom, were applied. Results Higher proportions of dental extraction were found in the municipalities with lower coverage by OHT (p<0.0001), lower HDI value (p<0.0001), and higher IPRS value (p=0. 0018). Conclusion Low coverage by OHT and socioeconomic inequalities contribute to increased proportion of dental extractions in the state of São Paulo.
RESUMO
ABSTRACT: Panoramic radiography has clinical importance in several dental specialties. The objective of this study was to evaluate the influence of professionals' experience and patient characteristics (age group and dental absence) in the prevalence of errors and the number of retakes in the panoramic radiography.771 panoramic radiographs were evaluated and classified according to the group of patients (children, dentulous adults, total edentulous adults, and anterior edentulous adults) and professionals who performed the technique (novice and experienced). The association between frequency and type of error, group of patients, professionals' experience, and number of retakes was performed by the Chi-square and Fisher's exact test (a=0.05). There was no significant association between the frequency of errors or retakes of the radiograph s and the professionals' experience or patients' characteristics (p<0.05). The errors "turned head" and "tongue not against the palate," "chin tipped low", "chin not resting on the support," "patient movement during exposure," and "lead apron artifact" showed significantly higher frequency of retake (p<0.05). The most frequent type of error was due to the failure to position the tongue against the palate for all patients and both groups of professionals. The frequency of errors in the panoramic radiography occurs regardless of the professionals' experience, and age and dental absence of the patients. Error occurs mainly due to the lack of patient collaboration, and the examination is rarely repeated by the professionals.
RESUMEN: La radiografía panorámica es de importancia clínica en varias especialidades dentales. El objetivo de este estudio fue evaluar la experiencia de los profesionales y las características de los pacientes (grupo etario y ausencia dentaria) en la prevalencia de errores y el número de repeticiones en la radiografía panorámica.771 radiografías panorámicas fueron evaluadas y clasificadas según la grupo de pacientes (niños, adultos desdentados, adultos desdentados totales y adultos desdentados anteriores) y profesionales que realizaron la técnica (novatos y experimentados). La asociación entre frecuencia y tipo de error, grupo de pacientes, experiencia de los profesionales y número de repeticiones se realizó mediante la prueba de Chicuadrado y exacta de Fisher (a = 0,05). No hubo asociación significativa entre la frecuencia de errores o repetición de las radiografías y la experiencia de los profesionales o las características de los pacientes (p <0,05). Los errores "cabeza girada" y "lengua no contra el paladar", "mentón inclinado hacia abajo", "mentón no apoyado en el soporte", "movimiento del paciente durante la exposición" y "artefacto del delantal de plomo" mostraron una frecuencia de repetición significativamente mayor (p < 0,05). El error más frecuente se debió a la falta de posicionamiento de la lengua contra el paladar para todos los pacientes y en ambos grupos de profesionales. La frecuencia de errores en la radiografía panorámica ocurre independientemente de la experiencia de los profesionales, edad y ausencia dentaria del pacientes. El error se produce principalmente por la falta de colaboración del paciente, y los profesionales rara vez repiten el examen.
RESUMO
Abstract This study aimed to estimate cost and compatibility with public financial incentives of two technologies for treating the edentulous mandible: lower complete dentures (CD) and overdentures retained by two dental implants (OD). This study consisted of a partial economic evaluation, with a micro-costing bottom-up approach for the calculation of direct costs. The estimates involved the number of consultations, proportion of materials, equipment, instruments' lifetime, and human resources, described in the price panel website of the Ministry of Economy in Brazil. Complementary information was obtained from a panel of experts. A sensitivity analysis was based on 20% variation. The estimated cost of a CD was R$ 189.89 (base scenario), and this varied between R$ 151.91 and R$ 227.89 according to sensibility analysis. The cost of an OD was R$ 663.05 (ranging from R$ 795.66 to R$ 530.44 - 1US=R$ 3.80/July 2019). The Ministry of Health covers appropriately the costs of the CD and OD. Both technologies showed costs that are within the limits of financial public incentives obtained by municipalities. The technologies are economically viable and should be induced through public policies due to their positive impacts on several functional domains of health.
Resumo Estimar os custos e a compatibilidade dos incentivos públicos de duas tecnologias para o tratamento da mandíbula edêntula: prótese total convencional (PTC) e overdenture retida por dois implantes (OD). Este estudo consistiu em uma avaliação econômica parcial, com abordagem "bottom-up" para o cálculo dos custos diretos. As estimativas levaram em consideração o número de consultas, proporção de materiais, equipamentos, vida útil dos instrumentais e recursos humanos. Os custos foram baseados no painel de preços do Ministério da Economia do Brasil e informações complementares foram obtidas de um painel de especialistas. Uma análise de sensibilidade foi baseada na variação de 20% dos custos. Os custos da PTC foram estimados em R$ 189,89 (cenário base) com variação entre R$ 151,91 e R$ 227,89 na análise de sensibilidade. Os custos da OD foram R$ 663,05 (variando de R$ 795,66 a R$ 530,44). O Ministério da Saúde cobre apropriadamente os custos de ambas as tecnologias nos cenários base e mais otimista. Ambas as tecnologias apresentaram custos dentro dos limites dos incentivos públicos recebidos. As tecnologias são economicamente viáveis e devem ser induzidas por políticas públicas diante do impacto positivo em vários domínios funcionais da saúde.

Introduction: Radiotherapy is one of the methods used as a treatment for malignant tumors in the head and neck region and it can cause tissue damage in the irradiated areas. In head and neck radiotherapy, teeth are often included within the irradiation area and, consequently, the dental pulp; which receives high doses of radiation. Objective: To evaluate the effects of ionizing radiation on the pulp tissue of rat teeth. Methodology: A double-blind experimental assay with 35 Albinus Wistar rats divided into seven groups was performed; one control group, three groups irradiated with 15 Gy, and three groups irradiated with 25 Gy. The irradiated groups were submit-ted to a single dose of radiation and sacrificed 24 hours, 7 days, and 22 days after irradiation, respectively. The samples were evaluated for the morphological presence of inflammatory infiltrate, edema, necrosis, fibrosis, and degeneration of blood vessels. Statistical analysis was performed using the Kruskal-Wallis and Dunn tests with p < 0.05. Results: Hyaline degeneration of the pulp blood vessels in the irradiated teeth was statistically signifi-cant in all irradiated groups. Inflammatory infiltrate, edema, necrosis or fibrosis was not observed. Conclusion:A single X-radiation dose is not able to affect the dental pulp connective tissue in the long term with no clinical damage.
Introdução: A radioterapia é um dos métodos utilizados como tratamento para tumores malignos em região de cabeça e pescoço e que pode causar danos aos tecidos nas áreas irradiadas. Na radioterapia de cabeça e pescoço, os dentes são comumente incluídos dentro da área de radiação e, consequentemente, a polpa dentária, recebe altas doses de radiação. Objetivo: Avaliar os efeitos da radiação ionizante no tecido pulpar de dentes de ratos. Metodologia: Foi realizado um ensaio experimental duplo-cego com 35 ratos Albinus Wistar divididos em sete grupos: um grupo controle, três grupos irradiados com 15 Gy e três grupos irradiados com 25 Gy. Os grupos irradiados foram submetidos a uma dose única de radiação e sacrificados 24 horas, 7 dias e 22 dias após a irradiação, respectivamente. As amostras foram avaliadas quanto à presença morfológica de infiltrado inflamatório, edema, necrose, fibrose e degeneração nos vasos sanguíneos. A análise estatística foi realizada por meio dos testes de Kruskal-Wallis e Dunn com p < 0.05. Resultados: Degeneração hialina nos vasos sanguíneos pulpares dos dentes irradiados foi estatisticamente significante em todos os grupos irradiados. Não foi observado infiltrado inflamatório, edema, necrose ou fibrose. Conclusão: Uma dose única de radiação X não é capaz de afetar o tecido conjuntivo da polpa dentária a longo prazo sem danos clínicos.

Objective: To evaluate the repercussions of the COVID-19 pandemic on procedures performed by a public urgent dental care service (PUDS). Methods: This was a cross-sectional study, using data from the PUDS in Piracicaba, SP, Brazil, prior to the pandemic (February-March 2020) and during the pandemic (March-April 2020). Differences in the care profile between the pre-COVID-19 period and the COVID-19 period, according to sex, age and dental procedures were analyzed using Pearson's Chi-square test. Effect size was also measured using Cramer's V. Results: There was a 51% reduction in the number of visits between the pre-COVID-19 period (n=824) and the COVID-19 period (n=404). The percentage of extractions reduced from 14.7% to 8.9%, while the percentage of temporary cavity fillings increased from 22.9% to 33.2%, between the two periods. Conclusion: The COVID-19 pandemic had repercussions on the amount and pattern of procedures performed at the city's urgent dental care service.

Aim:To evaluate the impact of the recording of teeth whose clinical conditions rarely vary (anterior teeth and third molars) in inter-examiner agreement measurements. Methods:Clinical data from 56 schoolchildren, 12 years of age, previously collected by two examiners, according to the "Oral Health Surveys: basic methods" codes and criteria, were analyzed in the present study. The effects from including/excluding such teeth upon reproducibility were measured by general percentage agreement (GPA) and Kappa statistics (к) performances. Results: The exclusion of anterior teeth associated with the inclusion of third molars produced a decrease in GPA that was simultaneous to an increase in the weighted Kappa (nominal data) and simple (dichotomous data) values. The incorrect inclusion of third molars (GPA = 100%; к = + 1) in the reproducibility measurement artificially increased the inter-examiner Kappa values. Conclusion: The inclusion/exclusion of anterior teeth and third molars, seeking a more reliable agreement among examiners, can have a positive or negative impact on the measured reproducibility values. A clear warning about the impact of including third molars in the reproducibility measurement, in the 12 years old age group, should be performed in "Oral Health Surveys: basic methods" and similar manuals.
Objetivo: Avaliar o impacto do registro de dentes anteriores e terceiros molares, cujas condições clínicas pouco variam, sobre as mensurações de concordância inter-examinadores. Métodos: Dados clínicos de 56 escolares de 12 anos de idade, previamente coletados por 2 examinadores, segundo os códigos e critérios expressos no "Levantamentos em Saúde Bucal: métodos básicos" foram analisados neste estudo. Os efeitos da inclusão/exclusão destes dentes sobre a concordância inter-examinadores foram mensurados calculando-se a porcentagem geral de concordância (GPA) e estatística Kappa (к). Resultados:A inclusão de terceiros molares aumentou a GPA para dados dicotomizados ou não. A exclusão de dentes anteriores diminuiu a GPA para dados dicotomizados ou não. Quando associada à inclusão de terceiros molares, sob perfeita concordância (к = +1), os valores de Kappa foram artificialmente aumentados tanto para dados dicotomizados quanto não-dicotomizados. Conclusão: A inclusão/exclusão de dentes anteriores e/ou de terceiros molares, no sentido de se evidenciar melhor as discordâncias entre examinadores, podem impactar positiva ou negativamente sobre a fidedignidade da reprodutibilidade mensurada. Uma advertência clara sobre o impacto da inclusão dos dentes terceiros molares no cálculo da reprodutibilidade, para a faixa etária de 12 anos, deveria estar presente no "Levantamentos em Saúde Bucal: métodos básicos" e manuais semelhantes.

Resumo Introdução estudos no Brasil e em diversos países indicam que os serviços de urgência são frequentemente utilizados como portas de entrada para os sistemas de saúde, sobrecarregando-os e impactando na qualidade do serviço prestado à população. Entretanto, pouco se conhece sobre esse fenômeno nas unidades de pronto atendimento (UPAs) do nosso país. Objetivo investigar as variáveis associadas ao uso inadequado de duas UPAs em um município de grande porte. Método estudo transversal com uma amostra de 756 indivíduos que analisou as variáveis individuais, contextuais e dos serviços associadas ao uso inapropriado de UPAs por meio de um modelo de regressão logística múltipla e hierarquizada. Resultados o modelo final de regressão demonstrou que os indivíduos que apresentavam autopercepção de que sua condição era um caso de emergência e cuja idade era igual a ou acima de 60 anos apresentaram mais chances de procurarem esses serviços por motivos não urgentes. Conclusão variáveis individuais estiveram associadas ao uso não urgente dos serviços das UPAs. Estudos futuros de cunho qualitativo poderão auxiliar a compreender os motivos do uso inadequado desses serviços por tais indivíduos.
Abstract Background Studies in Brazil and in several countries indicate that emergency services are often used as gateways to health systems, overburdening them and impacting on the quality of service provided to the population. However, little is known about this phenomenon in the Emergency Care Units (EUCs) of our country. Objective To investigate the variables associated with the inadequate use of two EUCs in a large municipality. Method A cross-sectional study was carried out with a sample of 756 individuals that analyzed individual, contextual and service-related variables associated with the inappropriate use of EUCs through a hierarchical multiple logistic regression model. Results The final regression model showed that individuals who had self-perceived their condition as an emergency and whose age was equal to or older than 60 years presented high odds to seek these services for non-urgent reasons. Conclusions Individual variables were associated with non-urgent use of the ECUs. Future studies of a qualitative nature may help to understand the reasons for the inadequate use of these services by these individuals.
RESUMO
Objective: This study aimed to evaluate the surface microhardness and morphology, as well as the microshear bond strength of a self-etching adhesive (Clearfil SE, Kuraray) to eroded dentin, exposed or not to cigarette smoke. Forty dental crowns were divided into 4 groups (n = 10): no treatment (control) (C); erosion (E); erosion + cigarette smoke exposure (ES); cigarette smoke exposure (S). Samples were prepared through third molars polishing until dentin exposure, followed by crown section. Erosive cycles were performed 5 times/day for 30 s at 60 min intervals. Cigarette smoke was produced with twenty cigarettes/day, during 5 days. Microhardness was evaluated initially and after the treatments. Microshear bond strength was tested after the treatments and dentin restoration with flow composite. Failure patterns and dentin morphology was evaluated by Scanning Electron Microscopy. Microshear bond strength data was submitted to two-way ANOVA, microharness test was adjusted by gamma distribution to be a non-parametric analyses (p=0.05), and surface morphology as qualitative analyses. Loss percentage of microhardness was observed only in groups submitted to erosion. Bond strength was statistically similar between all groups. The most prevalent failure pattern was of adhesive type. Morphological analysis of dentin showed obliterated tubules in groups submitted to cigarette smoke exposure. Cigarette smoke exposure did not promote any effect in the percentage of microhardness loss, as in sound dentin as in eroded dentin. Cigarette smoke, erosion, and association of both, did not alter the bond strength of self-etching adhesives to dentin. (AU)
Objetivo: Este estudo teve como objetivo avaliar a microdureza (% perda de dureza) e morfologia de superfície (MS), assim como a resistência de união (RU) de um adesivo autocondicionante (Clearfil SE, Kuraray) à uma dentina erodida, exposta ou não à fumaça de cigarro. Material e Métodos: Quarenta coroas dentais de terceiros molares foram seccionadas da raiz e polidas até a exposição dentinária, sendo aleatoriamente divididas em 4 grupos (n=10): sem tratamento (controle), erosão (E), erosão+ exposição a fumaça de cigarro (ES); exposição a fumaça de cigarro (S).O ciclo erosivo foi realizado 5 vezes/dia por 30s, com 60 minutos de intervalo entre eles. Os grupos ES e S foram exposto à fumaça de cigarro produzida por 20 cigarros/dia, durante 5 dias. A avaliação da microdureza foi realizada antes e após os tratamentos, enquanto a resistência da união por microcisalhamento foi realizada após os tratamentos Os padrões de fratura representativos e a MS dentinária foram avaliados por microscopia eletrônica de varredura (MEV). Os dados de RU foram analisados por ANOVA dois fatores, enquanto a análise de microdureza foi ajustada por distribuição gama por ser uma análise não-paramétrica (p=0.05). A MS foi analisada qualitativamente. Resultados: Os grupos expostos aos ciclos erosivos (E e ES) apresentaram % de perda de dureza significativamente menor que os grupos não expostos (Controle e S. aos ciclos erosivos (E e ES). Para RU, não houve diferença estatística significativa entre os grupos. O padrão de fratura mais observado foi do tipo adesivo, e através das imagens obtidas por MEV, observou-se a obliteração de túbulos dentinários no grupo exposto à fumaça de cigarro, enquanto os grupos submetidos aos ciclos erosivos (E e ES) apresentaram maior exposição e diâmetro de túbulos dentinários. Conclusão: A exposição à fumaça de cigarro não promove nenhum efeito quanto a perda de porcentagem de dureza dentinária, assim como em dentina erodida e saudável. A fumaça de cigarro, o processo erosivo, e a associação de ambos, não altera a resistência da união de adesivos autocondicionantes à dentina. (AU)

Abstract Objective: To make an association between self-perception and the implementation of sociodemographic variables for the autonomous and / or partially dependent individuals in nursing homes. Material and Methods: Epidemiological, observational and cross-sectional study. The sample consisted of 208 institutionalized elderly, both sexes, 60 years old or older, independent or partially dependent, randomly selected from two long-term residential institutions. Subjective evaluation: self-perception questionnaire, Geriatric Oral Health Assessment Index, quality of life assessment, Oral Impacts on Daily Performance (OIDP), oral health self-assessment (OH) and the need for dental prostheses. Bivariate analysis, chi-square test and multiple logistic regression were used, with the variables with p<0.05 remaining in the model. Results: Men were edentulous (53.43%), 68.75% used some type of denture, and 64.91% required dental prostheses, 60.58% self-assessed (OH) as good / excellent; who reported a need for dental prostheses presented 6.7 times (95% CI: 3.2-14.3) and more likely to have an impact on OIDP, those who needed prosthetics had a 2.8 times chance (95% CI: 1.3-6.1) (p<0.0001). The self-reported need for prostheses was associated with prevalence severity of impacts on QoL, eating, pronounce words correctly, Smile without feeling embarrassed; and the main reasons for not having badly adjusted teeth / dentures. Conclusion: The institutionalized elderly self-perceive the need for dental prostheses, but it does not have a negative impact on quality of life.

This in vitro study aimed to evaluate the effect of different toothpastes on dental enamel subjected to an erosive cycle with and without exposure to cigarette smoke. Bovine enamel specimens were randomly allocated into 12 groups (n = 12). For the in vitro simulation of smoking, half the groups underwent an exposure cycle of 20 cigarettes per day for 5 days. Subsequently, all groups were subjected to a 5-day erosion cycle intercalating demineralization (1 min; 1% citric acid; pH = 3.5) and treatment with toothpaste slurries (2 min) of NaF, SnF2, F/Sn/Chitosan, F/CaSiO3/Na3PO4, and F/bioactive glass. The control group was immersed in distilled water. Surface microhardness (SMH) was measured initially, after exposure to smoke, and after the erosive cycle, and %SMH was calculated. At the end of the experimental cycle, surface roughness, profilometry, and atomic force microscopy (AFM) were performed. SMH increased after exposure to cigarette smoke (p < 0.05). After the erosive cycle, there were no differences between the presence and absence of cigarette smoke exposure in SMH and roughness (p > 0.05). Besides increasing enamel SMH, cigarette smoke did not prevent enamel loss after the erosion cycle (p < 0.05). In profilometry, roughness and surface loss had the lowest values in the groups treated with SnF2 and F/Sn/Chitosan (p < 0.05). AFM showed lower mineral loss with F/CaSiO3/Na3PO4 and F/Sn/Chitosan. For all groups, except F/CaSiO3/Na3PO4, cigarette smoke resulted in higher enamel wear. F/Sn/Chitosan showed the best results against erosion.

OBJECTIVE: The aim of this study was to evaluate the relationship of the morphology of the articular eminence and mandibular fossa to facial profile and sex by using cone beam computed tomography (CBCT) images. STUDY DESIGN: CBCT examinations of 76 patients were conducted, and the patients were classified according to facial profile as dolichocephalic, mesocephalic, or brachycephalic. The inclination and height of the articular eminence and the inclination of the mandibular fossa of 152 temporomandibular joints were measured. Comparisons between these measurements and facial profile and gender were performed by 2-way analysis of variance with Tukey's post hoc test. Significance was established at αâ¯=â¯0.05. RESULTS: Males with brachycephaly presented significantly greater values of eminence inclination compared with those with other facial types and greater values than patients with dolichocephaly for the measurements of eminence height and inclination of the fossa posterior wall (P ≤ .05). Females with brachycephaly presented significantly greater eminence height values compared with those with other facial profiles (P ≤ .05). No significant differences were observed between males and females. CONCLUSIONS: The morphology of the articular eminence and the mandibular fossa is associated with facial profile, with males with brachycephaly showing greater inclination of the eminence and mandibular fossa. Articular eminence height in brachycephaly was greater in both sexes.
