Resumo O objetivo do artigo é analisar a clareza e as medidas de engajamento das publicações sobre câncer bucal nos perfis do Instagram dos órgãos oficiais de saúde no Brasil. Realizou-se um estudo infodemiológico com 81 perfis. Foram coletados dados sobre classificação do conteúdo, conta e mídia, abordagem do tema, número de postagens, curtidas, comentários, visualizações e hashtags. A clareza das publicações educativas foi avaliada pela versão brasileira do Clear Communication Index (BR-CDC-CCI). A análise dos dados envolveu a correlação de Spearman e o teste de Mann-Whitney (α = 5%). Foram encontradas 775 publicações sobre câncer bucal. O escore médio do BR-CDC-CCI foi 69,8 (DP = 15,5). A clareza das informações foi adequada em 9,5% das publicações educativas. Correlações positivas foram encontradas entre o número de curtidas e engajamento (comentários [r = 0,49], visualizações [r = 0,96]), número de hashtags (r = 0,13) e ano de publicação (r = 0,21). Publicações do Ministério da Saúde apresentaram escore do BR-CDC-CCI significativamente maior do que os demais perfis (p = 0,01). As publicações sobre câncer bucal foram correlacionadas com engajamento, ano de publicação e número de hashtags. Os órgãos públicos aumentaram as publicações para atingir a população, mas a clareza do conteúdo foi baixa.

ABSTRACT Objective: To determine the occurrence of hyposalivation in Brazilian adults and its association with individual determinants, such as the use of medications, systemic conditions, smoking, and alcohol consumption. Material and Methods: A cross-sectional study with 402 adults was developed. Information was collected on sociodemographic and general health characteristics, and sialometry was performed with stimulated salivary flow. It indicated low salivary flow when ≤ 0.7 mL/min. Bivariate and multivariate analyses were conducted using a decision tree (p<0.05). Results: The sample was comprised predominantly of women (68.2%) aged ≤ 29 years (25.4%). Most participants did not use medication (56.7%). Among systemic diseases, the most cited was hypertension (25.1%). More than a third of the participants presented hyposalivation (40.3%), being associated with the following variables: age between 50 to 59 years (p=0.011), female sex (p<0.001), menopause (p=0.001), use of alcohol (p=0.033), systemic disease (p=0.002) and medication use (p<0.001). In multivariate analysis, in addition to sex (p<0.001) and hypertension (p=0.005), an association was also found between hyposalivation and diabetes (p=0.014). Conclusion: Factors associated with hyposalivation in adults were sex and the presence of hypertension or diabetes.

Abstract Investigate individual and contextual determinants associated with bullying in schoolchildren eight to ten years of age. A cross-sectional study was conducted with 739 schoolchildren, who answered a question about episodes of bullying related to oral health and questionnaires addressing childhood anxiety and orofacial dysfunction. The guardians provided information on sociodemographic characteristics, sleep disorders, and oral health literacy. Trained examiners assessed the children for the diagnosis of dental caries using the International Caries Detection and Assessment System, malocclusion using the Dental Aesthetic Index, orofacial dysfunction using the Nordic Orofacial Test-Screening and traumatic dental injury (Andreasen criteria) (Kappa> 0.80). The contextual variables were the type of school and the monthly income of the school neighborhood. Descriptive statistics was performed to characterize the sample and unadjusted and adjusted (p <0.05) multilevel Poisson regression models were run. The prevalence of bullying was 13.3%. After the adjusted analysis, malocclusion (PR=1.59; 95%CI:1.03-2.44) and anxiety (PR=1.79; 95%CI:1.10-2.93) remained associated with bullying. In terms of context, the monthly income of the neighborhood of the school was associated with bullying (PR=1.75; 95%CI:1.12-2.72). Malocclusion and anxiety influenced the occurrence of bullying. A lower average income in the school neighborhood was an important contextual determinant for the increase in the prevalence of bullying.

Resumo Investigar determinantes individuais e contextuais associados ao bullying em escolares de 8 a 10 anos. Foi realizado estudo transversal com 739 crianças. As crianças responderam uma pergunta sobre episódios de bullying relacionado a saúde bucal, um questionário sobre ansiedade infantil e disfunção orofacial. Os responsáveis forneceram informações sobre características sociodemográficas, distúrbios do sono e alfabetismo em saúde bucal. Examinadores treinados avaliaram as crianças para diagnóstico da cárie dentária pelo International Caries Detection and Assessment System, má oclusão por meio do Dental Aesthetic Index, disfunção orofacial pelo Nordic Orofacial Test-Screening e traumatismo dentário (Critério de Andreasen) (Kappa>0,80). As variáveis contextuais foram tipo de escola e renda mensal do bairro escolar. Estatística descritiva foi utilizada para caracterização da amostra. Modelos de regressão de Poisson multinível não ajustados e ajustados (p<0,05) foram usados. A prevalência do bullying foi 13,3%. Após análise ajustada a má oclusão (RP=1.59; IC95%:1.03-2.44) e a ansiedade (RP=1.79; IC95%:1.10-2.93) permaneceram associados ao bullying. Em relação ao contexto, a menor renda mensal do bairro da escola foi associada ao bullying (RP=1.75; IC95%:1.12-2.72). Má oclusão e ansiedade influenciaram a presença do bullying. A menor renda mensal do bairro escolar foi um determinante contextual importante para o aumento da prevalência de bullying.

Abstract The study analyzed the clarity of publications on human papillomavirus (HPV) in the Instagram profiles of official Brazilian health agencies. An infodemiological study analyzed publications on HPV in the 81 Instagram profiles selected from the Health Ministry, States’ Health Departments, and dental councils and associations. The following data were collected: classification of content, type of profiles, type of media, how the content was addressed, number of posts, frequency, likes, comments, viewings, and hashtags, and how the HPV vaccine was addressed. The clarity of the educational publications was assessed using the Brazilian version of the Clear Communication Index (BR-CDC-CCI). Data analysis was performed with Spearman’s correlation and the Mann-Whitney test (p < 0.05). A total of 504 publications on HPV were found. The average number of likes was 528.3 (SD = 2388.2) and the average BR-CDC-CCI score was 67.1 (SD = 14.1). The quality and clarity of the information was considered adequate (BR-CDC-CCI score ≥ 90) in 6.9% of the publications. A weak positive correlation was found between the number of likes and both the BR-CDC-CCI score (r = 0.195) and number of posts (r = 0.124). Publications from the Health Ministry had a significantly higher BR-CDC-CCI score (72.9) compared to the other profiles analyzed (p = 0.01). Most publications concerned government actions, had low engagement, and written educational information was of low clarity and quality. However, the effort to reach the population was evident, with an increase in publications over the years.

Métodos Estudio transversal con muestra de 293 historias de pacientes portadores de CEC, atendidos en un Centro de Referencia de Oncología del municipio de Campina Grande (PB), de 2000 a 2006. Se utilizó estadística descriptiva e inferencial por medio de la Regresión Robusta de Poisson (α=5%). Resultados El sexo masculino (56,6%), los no blancos¿? (49,0%) y el grupo de más de 60 años (74,1%) fueron los más afectados por la neoplasia; la lengua (35,1%) y el paladar (21,5%) fueron los sitios más afectados; la mayoría poseía hábito de tabaquismo (37,6%) y el 60,2% presentaba etapa avanzada de la enfermedad. La estadificación clínica no se asoció al sexo, la edad, el color de la piel y a los hábitos de beber y/o fumar. Conclusiones Se observó una mayor ocurrencia de CEC en hombres, en pacientes con edad más avanzada, no blancos y que poseían hábitos de tabaquismo, pero sin asociación estadística.

ABSTRACT Objective The aim of the present study was to identify the profile of patients diagnosed with oral squamous cell carcinoma (SCC) and factors associated with the clinical stage of the disease. Materials and Method A cross-sectional study was conducted with a sample of 293 medical charts of patients with SCC treated at an oncology reference center in the city of Campina Grande (Brazil) between 2000 and 2006. Descriptive and inferential statistics were performed with robust Poisson regression (α=5%). Results Males (56.6%), non-white individuals (49.0%) and individuals over than 60 years of age (74.1%) were the most affected by SCC. The tongue (35.1%) and palate (21.5%) were the most common sites. A large portion of the patients were smokers (37.6%) and 60.2% were in an advanced stage of the disease. Clinical staging was not associated with sex, age, skin color or drinking and/or smoking habits. Conclusion There was a higher incidence of SCC in men, older patients, non-white individuals and smokers. Clinical staging was not associated with the variables analyzed.

O objetivo do presente estudo foi verificar a eficácia de um protocolo oral preventivo em crianças com leucemia linfoblástica aguda (LLA), submetidas ao tratamento antineoplásico, antes de iniciar um estudo mais abrangente. Durante um período de sete meses, foram avaliadas, consecutivamente, quatorze crianças com LLA, de dois a dez anos de idade. As crianças com LLA que fizeram bochechos com a solução de clorexidina 0,12% (sete crianças) foram comparadas com aquelas do grupo controle (sete crianças) no que diz respeito ao surgimento de lesões orais. Todas as crianças do estudo receberam diariamente orientação de higiene oral e foram igualmente examinadas pelo odontopediatra. Observou-se uma diminuição significativa na incidência de mucosite e ulceração oral nas crianças que fizeram bochecho profilático com clorexidina 0,12% (p < 0,05, teste exato de Fisher). Os achados obtidos no presente estudo são satisfatórios, e sugerem que uma aplicação sistemática de um protocolo preventivo reduza a incidência de complicações orais em crianças com LLA submetidas à quimioterapia.

This study was designed to assess the effectiveness of a preventive oral protocol in children receiving antineoplastic treatment for acute lymphoblastic leukemia (ALL) before initiating a larger intervention study. During a seven month period, fourteen children from two to ten years old with a diagnosis of ALL were evaluated. Patients with ALL who received a 0.12% chlorhexidine mouth rinse (seven children) were compared to a control group of patients who were not given the same preventive treatment (seven children) as to the occurrence of oral mucosal complications. Children in both groups received daily oral hygiene care, and were examined daily by the pediatric dentistry team until discharge. A significant decrease in the incidence of oral mucositis and ulceration was observed in the children who received a 0.12% chlorhexidine mouth rinse (p < 0.05 by Fisher's exact test). The findings obtained in the present trial are encouraging, and suggest that the systematic application of a preventive protocol reduces the incidence of oral complications in children with ALL receiving chemotherapy.
