RESUMO

The increasing number of cases of COVID-19 worldwide poses challenges to healthcare systems not only in effectively identifying individuals positive for SARS-CoV-2, but also in isolating cases to minimise contagion in early diagnosing more severe cases that will need hospitalization. Less-invasive collection methods are indispensable in a pandemic scenario as large-scale tests are necessary to understand the actual evolution of contagion in different populations, thus enabling decision-making based on scientific evidence. Saliva has been shown to be an alternative for diagnosing viral infections as this biological fluid can be easily and quickly collected without using specific devices and causing less discomfort during collection, which is an important factor for use in children. Despite the smaller percentage of severe cases of COVID-19 among children, they seem to play an important role in the contagion as they have the same potential of transmission as that of adults. Knowing the evolution of COVID-19 pandemic in children is extremely important, mainly regarding the changing in rules of social distancing, such as re-opening schools and recreational activities spaces. In addition, countless cases of a severe multi-systemic inflammatory syndrome that shares clinical and laboratory features with Kawasaki's disease have been recently related to SARS-CoV-2 infections in children, adolescents and young adults. In view of this scenario, the aim of this study was to present saliva as an alternative for seeking diagnostic and prognostic markers of COVID-19 in children, including adequate sample collection techniques for different age groups.

RESUMO

The presence of dental abnormalities in the same individual may be related to syndromic cases and occur through associated systemic changes. Kabuki syndrome presents well-defined systemic changes, but its clinical characteristics related to the oral cavity have not been fully explained. This study aimed to report the dental changes in a child diagnosed with Kabuki syndrome. A male brown patient aged 2 years and 7 months, accompanied by his mother to the dental visit, they main complaint was the presented of an additional tooth behind upper right central incisor. Anamnesis, intra- and extraoral examinations, and dental X-rays were performed, revealing a talon cusp. Considering the dental clinical findings, the patient was referred to a medical geneticist who additionally requested cardiological and genetic examinations, which established the Kabuki syndrome. The caregivers were advised that the talon cusp would not cause any injury to the natural exfoliation of the tooth and that oral hygiene should be performed carefully. Abnormalities in the oral cavity and developmental delay may be associated with a potential undiagnosed syndrome. The medical evaluation becomes decisive for investigation, diagnosis, and final conduct of the case.

RESUMO

Abstract Objective: To assess the short-term effect of two in vitro erosive challenge protocols on the bond strength of metal orthodontic brackets on bovine enamel. Methods: Sixty bovine incisors were selected and randomly divided into six groups: AS7 (artificial saliva - 7 days, Control Group); CC7 (Coca-Cola™ - 7 days); LJ7 (lime juice - 7 days); AS30 (artificial saliva - 30 days, Control Group); CC30 (Coca-Cola™ - 30 days); LJ30 (lime juice - 30 days). Microhardness testing was performed prior to the erosive challenge to verify the standardization of samples. Immersion was performed 4x/day for five minutes, for either 7 or 30 days. After immersions were concluded, the brackets were bonded and shear bond strength was assessed after 48 hours. The Adhesive Remnant Index (ARI) was also assessed. Data were analyzed by two-way ANOVA, followed by Tukey's post-hoc and Student's t test for paired samples, and the Kruskal-Wallis non-parametric test (α = 5%). Results: The mean and standard deviation of microhardness testing of total samples were 281.89 ± 44.51 KHN. There was no statistically significant difference in shear bond strength for the time factor (7 or 30 days; F5.54= 0.105; p = 0.901). However, there was a statistically significant difference for the solution factor (F5.54= 6.671; p = 0.003). These differences occurred among solutions of Saliva x Coca-Cola™ (p = 0.003) and Coca-Cola™ x Lime Juice (p= 0.029). The assessment of the Adhesive Remnant Index showed no significant difference between groups. Conclusions: The immersion time used in the erosion protocols did not affect the bond strength of brackets to teeth. Coca-Cola™ induced significantly higher shear bond strength values than lime juice and artificial saliva. However, the short term effects of 7/30 days in this in vitro study may not be extrapolated for in vivo ones. Clinical studies should be conducted, substantiating the laboratory results.


Resumo Objetivo: avaliar o efeito de curto prazo de dois protocolos de desafio erosivo, in vitro, na resistência adesiva de braquetes ortodônticos metálicos em esmalte bovino. Métodos: Sessenta incisivos bovinos foram selecionados e divididos aleatoriamente em seis grupos: SA7 (saliva artificial - 7 dias, Grupo Controle); CC7 (Coca-Cola® - 7 dias); SL7 (suco de limão - 7 dias); SA30 (saliva artificial - 30 dias, Grupo Controle); CC30 (Coca-Cola® - 30 dias); SL30 (suco de limão - 30 dias). Foi realizado o teste de microdureza antes do desafio erosivo, para verificar a padronização das amostras. A imersão foi realizada quatro vezes ao dia, por cinco minutos, durante 7 ou 30 dias. Finalizadas as imersões, os braquetes foram colados e, após 48 horas, foi avaliada a resistência ao cisalhamento. O Índice de Adesivo Remanescente (IAR) também foi avaliado. Para análise dos dados, foram utilizados os testes ANOVA dois fatores, seguido do post-hoc de Tukey e teste t de Student para amostras pareadas, e o teste não-paramétrico de Kruskal-Wallis (α?#8197;= 5%). Resultados: a média e o desvio-padrão do teste de microdureza das amostras totais foi igual a 281,89 ± 44,51 KHN. Não houve diferença estatisticamente significativa na resistência ao cisalhamento para o fator tempo (7 ou 30 dias; F5,54= 0,105; p= 0,901). Contudo, houve diferença estatisticamente significativa para o fator solução (F5,54=6,671; p= 0,003). Essas diferenças ocorreram entre as soluções de Saliva x Coca-Cola® (p= 0,003) e Coca-Cola® x suco de limão (p= 0,029). Ao avaliar o Índice de Adesivo Remanescente, não foi possível verificar diferença significativa entre os grupos. Conclusões: o tempo de imersão utilizado nos protocolos de erosão não afetou a resistência de união dos braquetes aos dentes. A Coca-Cola® induziu valores de resistência ao cisalhamento significativamente mais altos do que o suco de limão e a saliva artificial. No entanto, os efeitos em curto prazo de 7 e 30 dias, nesse estudo in vitro, não podem ser extrapolados para os estudos in vivo. Estudos clínicos devem ser conduzidos, fundamentando os resultados laboratoriais.

RESUMO

CONTEXT AND OBJECTIVES:: Anxiety is usually classified as a disorder of neurotic nature and is often related to contexts of stress, which may include worries, motor tension and autonomic hyperactivity. The aim of this study was to assess the influence of mothers' anxiety on their children's anxiety during dental care. DESIGN AND SETTING:: Analytical cross-sectional study conducted at in a private dentistry school in the south of Brazil. METHODS:: Convenience sampling was used. All mothers of children undergoing treatment were invited to participate in this study. Data to investigate anxiety related to dental treatment among the children were collected through applying the Venham Picture Test (VPT) scale. For the mothers, the Corah scale was applied. A self-administered sociodemographic questionnaire with questions about demographic, behavioral, oral health and dental service variables was also used. RESULTS:: 40 mother-child pairs were included in the study. The results showed that 40% of the children were anxious and 60% of the mothers were slightly anxious. Local anesthesia was the procedure that caused most anxiety among the mothers, making them somewhat uncomfortable and anxious (60%). Family income higher than R$ 1,577.00 had an influence on maternal anxiety (75.6%). Maternal anxiety had an influence on child anxiety (81.3%). CONCLUSION:: Most of the children showed the presence of anxiety, which ranged from fear of dental care to panic, inferring that maternal anxiety has an influence on children's anxiety. Dental procedures did not interfere with the mothers' anxiety, but caused positive feelings, whereas they affected the children more.

RESUMO CONTEXTO E OBJETIVO: A ansiedade é geralmente classificada como um transtorno de caráter neurótico, frequentemente relacionado a contextos de estresse variando entre preocupações, tensão motora e hiperatividade autonômica. O objetivo desta pesquisa foi avaliar a influência da ansiedade materna na ansiedade de seu filho durante o atendimento odontológico. TIPO DE ESTUDO E LOCAL: Estudo analítico transversal realizado em uma faculdade particular do sul do Brasil. MÉTODOS: Amostragem por conveniência foi utilizada. Todas as mães das crianças em tratamento foram convidadas a participar da pesquisa. A coleta dos dados para verificar a ansiedade relacionada com o tratamento odontológico nas crianças foi realizada a partir da aplicação da escala “Venham Picture Test” (VPT). Para as mães, foi utilizada a escala de Corah. Também se utilizou um questionário sociodemográfico autoaplicativo sobre variáveis demográficas, comportamentais, de saúde bucal e de serviço odontológico. RESULTADOS: Foram incluídos 40 pares de mães e crianças. Os resultados mostraram que 40% das crianças estavam ansiosas e 60% das mães estavam levemente ansiosas. A anestesia local foi o procedimento que causou mais ansiedade entre as mães, deixando-as um pouco desconfortáveis e ansiosas (60%). Renda familiar maior de R$ 1.577,00 influenciou a ansiedade materna (75.6%). A ansiedade materna influenciou a ansiedade das crianças (81.3%). CONCLUSÃO: A maioria das crianças apresentou ansiedade, o que variou do medo ao pânico ao atendimento odontológico, inferindo que a ansiedade materna tem influência na ansiedade dos seus filhos. Os procedimentos odontológicos não interferem na ansiedade das mães, atingindo mais as crianças, porém provocam sentimentos positivos.

RESUMO

Objective: To perform a systematic review relating the existence of root resorption during orthodontic treatment. Methods: The research was performed in two electronic databases (PubMed and OpenGrey). The OpenGrey database was used exclusively for searching the "grey literature", avoiding selection and publication bias. Eligibility criteria included full texts available online, but with no language restriction. Aiming to work with more current articles on the subject, a filter for thelast ten years was applied. Articles that had no direct relation with the main outcome of this study were excluded, as well as clinical case reports and opinions, literature review articles, editorials, and letters to the editor. All eligible studies were assessed for risk of bias and individual quality, and all research steps were performed independently by two eligibility reviewers. Results: Initially, 77 articles were selected, but after the application of exclusion criteria, only 71 were included. Six articles were eligible for qualitative assessment. Overall, incisors are the teeth most affected by root resorption and there is a higher rate of root resorption in retraction mechanics. Conclusion: There is a relationship between root resorption and orthodontic treatment.

RESUMO

The cephalometric analysis has assisted orthodontics in describing face features in terms of numbers/angles, but these results are not always consistent with ideal individual patterns. Some orthodontists have made use of subjective analysis as an auxiliary method in the diagnosis; however, the consistency of the reproducibility of these methods has been questioned. Hence, this study aimed to verify whether the diagnosis of sagittal facial patterns can be accomplished with a reliable reproduction. This is an analytical observational study including an initial sample of 120 teleradiographs and 120 photographs in lateral norm of patients from the Graduate Program in Dentistry, Faculty of Health of the Methodist University of São Paulo. First, a previously calibrated examiner separated the photographs into three Sagittal Facial Patterns (Pattern I, II and III). Thus, it was obtained three groups comprising 45 photographs for the Pattern I; 45 photographs for the Pattern II and 30 photographs for the Pattern III. After this initial selection, the cephalometric analysis of 120 teleradiographs was performed using measurements of ANB and SN-GoGn angles. From this second analysis, it was selected only the photographs in which the result of subjective analysis matched the cephalometric analysis, totalizing a final sample size of 52 photographs. These 52 photographs were separated and set on an album to be reassessed by 19 orthodontists, in order to observe or not an agreement between the facial patterns among professionals. The kappa test analyzed the level of agreement of 19 professionals in relation to the cephalometric reference. The degree of agreement between professional judgment and cephalometry was found to be 73.08%, and the result of the kappa test was 0.59 (moderate agreement). Taken together, the accuracy in the diagnosis of facial pattern by means of subjective facial analysis demonstrates that the subjective method is reliable for clinical use.


A análise cefalométrica auxiliou a ortodontia a descrever numericamente as características da face, mas nem sempre estes resultados condizem com os padrões individuais ideais. Alguns ortodontistas utilizam análises subjetivas como método auxiliar no diagnóstico, porém a reprodução do método é discutida. Sendo assim, o trabalho objetiva verificar se o diagnóstico do Padrão sagital da face é possível de ser realizado com reprodução confiável. Trata-se de um estudo observacional analítico com uma amostra inicial de 120 telerradiografias e 120 fotografias em norma lateral de pacientes pertencentes ao Programa de Pós-Graduação em Odontologia da Faculdade da Saúde da Universidade Metodista de São Paulo. Primeiramente, um avaliador, previamente treinado, separou as fotografias nos Três Padrões sagitais da face (Padrão I, II e III). Dessa forma obtiveram-se três grupos compostos por 45 fotografias no Padrão I; 45 fotografias no Padrão II e 30 fotografias no Padrão III. Após essa seleção inicial foi realizado a análise cefalométrica das 120 telerradiografias desses pacientes utilizando as medidas dos ângulos ANB e SN.GoGn. A partir dessa segunda análise foram selecionadas apenas as fotografias em que o resultado da análise subjetiva coincidiu com a análise cefalométrica resultando em um novo número amostral final de 52 fotografias. Estas 52 fotografias foram separadas e montadas em um álbum para serem reavaliadas por 19 ortodontistas com o intuito de observar ou não a concordância dos Padrões Faciais entre os profissionais. Para a análise de dados utilizou-se o Teste Kappa com o intuito de analisar o nível de concordância dos 19 profissionais com a referência cefalométrica. Dessa forma, o grau de concordância entre a avaliação profissional e a cefalometria encontrado foi de 73,08% sendo o resultado do Teste Kappa de 0,59 - considerado moderado. Conclui-se que existe exatidão no diagnóstico do padrão facial por meio da analise subjetiva da face, o que demonstra que este método subjetivo é confiável para a utilização na prática clínica.
