Abstract: Deleterious oral habits (DOH) have been described as a common finding in pediatric series. Studies have investigated their association with local and systemic health problems. In this study, the association between DOH and asthma was investigated. PubMed, Scopus, Lilacs, Web of Science, Google Scholar, and OpenThesis were accessed to identify observational studies that evaluated the association between DOH (thumb sucking, pacifier use, onychophagia or nail biting, bottle feeding) and asthma in children aged 2–17 years. Information on DOH was obtained from the verbal report of the children’s parents. Asthma diagnosis was performed by a physician or using the International Study of Asthma and Allergies in Childhood (ISAAC) questionnaire. We used a random-effects model to pool the results. The odds ratio (OR) was used as measure of association between DOH and asthma. The National Institutes of Health Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies was used to assess risk of bias. The GRADE approach was used to assess the quality of evidence. Five studies were included and data from 18,733 children aged 2 to 13 years were analyzed. We found an association between bottle feeding and asthma (OR = 1.25; 95%CI 1.13–1.38; p < 0.001) with moderate level of certainty. Despite the association between pacifier use and asthma (OR = 1.11; 95%CI 1.00–1.24; p = 0.05), the quality of evidence was low. Only one study provided data on nail biting and thumb-sucking, and the individual results showed no association between these habits and asthma. This meta-analysis found an association between bottle feeding, pacifier use, and asthma in children.

SUMMARY The coronavirus pandemic (COVID-19) brought up discussions about improvements in both primary healthcare and hospital care in Brasil. In addition, the use of information and communication technology tools has become more prominent in the transmission of health information to patients remotely. Through content dissemination actions for professionals and direct guidance to users, remote telehealth/telemedicine services offer qualified actions that can reduce unnecessary referrals and decrease the flow of patients in health units. Information and communication technologies are allies in the fight against COVID-19.

SUMMARY The pandemic of Coronavirus Disease 2019 (COVID-19) has put pressure on countries’ health systems. Although attention is mostly directed at the hospital sector, since many critically ill people will need intensive care, Primary Health Care (PHC) has also been disrupted. In Brasil, a universal and free health system has existed since the 1988 Constitution, which re-organized the PHC to attend the population. However, like other countries, the Brazilian health system is being overloaded with the increase in the large number of COVID-19 cases. It is worth reflecting on the changes and challenges in PHC during the COVID-19 pandemic in Brasil.

The emergence of severe acute respiratory coronavirus 2 (SARS-CoV-2) and its association with severe pneumonia and deaths has exposed gaps in the health systems of several countries worldwide. Although the necessary focus has been to care for hospitalized patients, the strengthening of Primary Health Care (PHC) actions is necessary. PHC is the gateway to the health system in several countries, including Brazil and it plays a role in preventing, protecting, promoting, and treating individuals and communities. Brazil, like other countries, has faced the SARS-CoV-2 pandemic. As Brazil has a universal and decentralized health system, in which PHC has been the model of health re-organizing the health system; here we reflected the importance of strengthening PHC in Brazil in the times of coronavirus disease 2019 pandemic.

RESUMO Como o SARS-CoV-2, que causa síndrome respiratória aguda grave, é transmitido principalmente por gotículas, espirros e aerossóis, há um alto risco de transmissão durante os procedimentos odontológicos. Este relatório descreve os passos que podem ser tomados pelo pessoal de saúde oral para minimizar o risco de contaminação cruzada na prática clínica durante a actual pandemia do SARS-CoV-2.

ABSTRACT As the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is transmitted mainly through droplets, sneezes and aerosols, there is a high risk of transmission during dental procedures. This report describes measures that can be adopted by oral healthcare personnel to minimize the risk of cross-contamination in clinical practice during the current SARS-CoV-2 pandemic.

RESUMEN Dado que el SARS-CoV-2, causante de síndrome respiratorio agudo severo, se transmite principalmente por medio de gotitas, estornudos y aerosoles, existe un alto riesgo de transmisión durante los procedimientos dentales. En este informe se describen las medidas que puede adoptar el personal de salud bucodental para reducir al mínimo el riesgo de contaminación cruzada en la práctica clínica durante la actual pandemia por SARS-CoV-2.

Resumo Contexto O estudo do fenômeno de fadiga é essencial porque as falhas de implantes geralmente são causadas por este processo. Objetivo O objetivo deste estudo foi analisar a resistência à fadiga de conjuntos de pilares retos e anatômicos que foram submetidos a cargas cíclicas. Material e método Foram utilizados 37 implantes cone Morse e 37 pilares, divididos em dois grupos (n = 16: pilares retos, n = 21: pilares anatômicos). Os conjuntos foram submetidos à carga cíclica (5.000.000) usando o equipamento servo-hidráulico. Três conjuntos de cada grupo foram submetidos a testes de flexão para determinar a resistência de carga máxima, o que serviu de parâmetro para comparação dos testes cíclicos. Foram avaliados número de ciclos, carga e momento de flexão. Resultado Dos 31 pilares ciclicamente testados, 17 (54,8%) fraturaram em menos de 5 milhões de ciclos; 8 (25,8%) destes eram pilares retos, e 9 (29%) eram anatômicos. Um total de 14 amostras (45,2%) resistiu à carga cíclica. De acordo com o teste exato de Fisher, não houve diferença entre os grupos quanto à fratura. Conclusão Apesar dos pilares retos terem maior carga média e momento de flexão que os anatômicos, os dois tipos de pilares apresentaram desempenho semelhante quanto a resistência à fratura in vitro.

Abstract Background The study of the phenomenon of fatigue is essential because implant failures usually are caused by this process. Purpose The objective of this study was to examine the fatigue resistance of straight and anatomical abutments joints that were submitted to cyclic loads. Material and method We used 37 Morse taper implants and 37 abutments, divided into two groups (n= 16: straight abutment, n= 21 anatomical abutment). The sets were submitted to cyclic loading (5 million) using servo-hydraulic equipment. Three sets from each group were subjected to bending tests to determine the maximum load resistance, which served as the parameter for comparison of the cyclic tests. We evaluated number of cycles, load and bending moment. Result Of the 31 abutments cyclically tested, 17 (54.8%) fractured in fewer than 5 million cycles; 8 (25.8%) of these were straight abutments, and 9 (29%) were anatomical. A total of 14 samples (45.2%) resisted the cyclic loading. According to Fisher's exact test, there was no difference between groups as the fracture. Conclusion Despite of the straight abutments have higher average load and bending moment on the anatomical, both types of abutments showed similar performance as the fracture strength in vitro.

INTRODUÇÃO: A incidência do câncer de boca varia amplamente no mundo, sendo que dois terços dos casos têm sido diagnosticados em países em desenvolvimento. OBJETIVO: Investigar a epidemiologia dos óbitos por câncer de boca e a distribuição espacial no município de Aracaju, estado de Sergipe, entre 2000 e 2009. MATERIAL E MÉTODO: Os dados foram coletados do Sistema de Informação de Mortalidade (SIM) de Aracaju/SE e no site do DATASUS e foram tabulados através do Tabwin 3.4. Foi realizada a distribuição geográfica dos óbitos por bairros desta cidade. RESULTADO: Dos 78 óbitos, 61 (78,2%) eram do sexo masculino. A média de idade foi 64,23 anos. A maior frequência de óbitos foi em indivíduos de cor parda (34,6%). Quanto à escolaridade, a maioria das declarações de óbito registrou a opção ignorada, seguida de indivíduos com 1 a 3 anos de estudo. Os sítios anatômicos mais acometidos foram partes não especificadas da boca (43,6%). A análise da distribuição espacial mostrou que os bairros Santos Dumont, Luzia, Atalaia, Santa Maria, Cidade Nova e Industrial apresentaram as maiores frequências de óbito. CONCLUSÃO: O perfil epidemiológico delineado foi de indivíduos do sexo masculino, entre a quinta e sexta décadas de vida, de cor parda, baixa escolaridade e nos bairros com baixa ou muito baixa condição de vida.

INTRODUCTION: The incidence of oral cancer varies widely in the world, with two thirds of cases diagnosed in developing countries. OBJECTIVE: To investigate the epidemiology of deaths from oral cancer and the spatial distribution in the city of Aracaju in the state of Sergipe between 2000 and 2009. MATERIAL AND METHOD: Data were collected using the Mortality Information System (MIS) of Aracaju/SE at the DATASUS website and were tabulated using the software TABWIN 3.4. The geographic distribution of deaths by neighborhoods of that city was visualized. RESULT: Of the 78 deaths, 61 (78.2%) were male. The mean age was 64.23 years. Individuals of mixed ethnicity had a higher death frequency (34.6%). Regarding education, the majority of death certificates recorded the option ignored, followed by individuals with 1 to 3 years of study. The anatomical sites most affected were unspecified parts of the mouth (43.6%). The spatial distribution analysis indicated that neighborhoods such as Santos Dumont, Luzia, Atalaia, Santa Maria, Cidade Nova and Industrial had the highest death frequencies. CONCLUSION: Males between the fifth and sixth decades of life of mixed ethnicity, low education and in neighborhoods with low and very low standards of living constitute the epidemiological profile for deaths from oral cancer.
