Abstract This article aims to analyze the clarity and engagement measures of publications on oral cancer in the Instagram profiles of official health agencies in Brazil. An infodemiological study was conducted with 81 profiles. Data collected concerned content classification, account and media, manner of addressing the topic, number of posts, likes, comments, views and hashtags. The clarity of the educational publications was assessed with the Brazilian version of the Clear Communication Index (BR-CDC-CCI). Data analysis involved Spearman’s correlation and the Mann-Whitney test (α = 5%). A total of 775 publications on oral cancer were found. The average BR-CDC-CCI score was 69.8 (SD = 15.5). The clarity of the information was adequate in 9.5% of the educational publications. Positive correlations were found between the number of likes and engagement (comments [r = 0.49], views [r = 0.96]), number of hashtags (r = 0.13) and year of publication (r = 0.21). Publications from the Health Ministry had a significantly higher BR-CDC-CCI score compared to the other profiles. Publications on oral cancer were correlated with engagement, year of publication and number of hashtags.

Abstract Objective: To investigate the usefulness, reliability, quality, and content of Portuguese-language YouTube videos on COVID-19. Material and Methods: Three keywords selected on Google Trends were searched on YouTube, and the 60 first videos listed with each term were analyzed. Two calibrated researchers evaluated the reliability (DISCERN Modified Scale), the quality (Global Quality Score - GQS), and the usefulness of videos for the users (COVID-19 Specific Score - CSS). The number of views, likes, and engagement were also analyzed. The data were evaluated by the Mann-Whitney test and Spearman correlation (α=5%). Results: 59 videos were included. The average scores of quality, reliability, and usefulness were 3.0 (±1.1), 3.2 (± 0.8), and 1.5 (± 0.9), respectively. Two-thirds of the videos (64.4%) had low/moderate quality, and the majority (76.2%) were about signs and symptoms. The numbers of views (p=0.005), likes (p=0.006), and engagement (p=0.014) were significantly higher in moderate/good quality videos. The number of comments (p=0.007), duration of videos (p=0.004), and the DISCERN score (p<0.001) were significantly higher in videos made by health professionals. The general quality of the videos was positively correlated to the CSS scores, number of views, likes, and engagement (p<0.05). Conclusion: Most videos had moderate quality and reliability and low usefulness for the users. Objective Portugueselanguage Portuguese language COVID19.

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 The aim of this study was to undertake a cross-cultural adaptation of the eHealth Literacy Scale (eHEALS) instrument to measure digital health literacy of Brazilian adolescents. eHEALS is a scale consisting of 8 items that measure self-perception related to the consumption of electronic health information. This is a methodological study of cross-cultural adaptation, conducted out from February 2022 to June 2022. The following steps were carried out: a) assessment and adequacy of cultural equivalence by a committee of experts; b) back-translation; c) synthesis of back-translations; d) cognitive testing with 42 Brazilian adolescents, using cognitive interviews with probing questions. All items that were difficult to understand were adapted to the (language) context of Brazilian adolescents. Cronbach’s alpha coefficient for eHEALS-BrA was 0.81 and, if one of the items were excluded from the instrument, it ranged from 0.75-0.81. This version of the eHEALS proved to be culturally well-adapted to the context of Brazilian adolescents, and has the potential to measure digital health literacy in this population after having its validation confirmed through psychometric analyses. crosscultural cross (eHEALS adolescents selfperception self perception information 202 experts b backtranslation back translation back-translation c backtranslations translations back-translations d 4 questions language (language Cronbachs Cronbach s eHEALSBrA BrA 081 0 81 0.8 0.750.81. 075081 0.75 0.81. 75 0.75-0.81 welladapted well analyses 20 08 0. 750 0.750.81 07508 075 0.7 7 0.75-0.8 2 0.750.8 0750 07 0.75-0. 0.750. 0.75-0 0.750 0.75-

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. age crosssectional cross sectional 73 characteristics disorders literacy System Index TestScreening Test Screening Andreasen criteria Kappa> Kappa (Kappa 0.80. 080 0.80 . 0 80 0.80) p <0.05 005 05 run 133 13 3 13.3% analysis PR=1.59 PR159 PR 1 59 (PR=1.59 95%CI1.032.44 95CI103244 CI 95%CI 1.03 2.44 95 03 2 44 95%CI:1.03-2.44 PR=1.79 PR179 79 (PR=1.79 95%CI1.102.93 95CI110293 1.10 2.93 10 93 95%CI:1.10-2.93 context PR=1.75 PR175 75 (PR=1.75 95%CI1.122.72. 95CI112272 1.12 2.72 12 72 95%CI:1.12-2.72) 7 08 0.8 8 <0.0 00 13.3 PR=1.5 PR15 5 (PR=1.5 CI1 032 95%CI1.032.4 95CI10324 95CI 103 1.0 244 2.4 9 4 95%CI:1.03-2.4 PR=1.7 PR17 (PR=1.7 102 95%CI1.102.9 95CI11029 110 1.1 293 2.9 95%CI:1.10-2.9 122 95%CI1.122.72 95CI11227 112 272 2.7 95%CI:1.12-2.72 0. <0. 13.

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. 1 anos 73 bucal sociodemográficas System Index TestScreening Test Screening Critério Andreasen Kappa>0,80.

Abstract The present study aimed to perform the cross-cultural adaptation of the Digital Health Literacy Instrument (DHLI) for native Brazilian Portuguese-speaking adolescents (DHLI-BrA). Cross-cultural adaptation consisted of the following steps: translation, assessment, and adjustments by the expert committee to ensure cultural equivalence; back-translation, and synthesis of back-translations. Cognitive testing was then performed in a pretest with adolescents using cognitive interviews with probing questions on the item's understanding interpretation and response options. Cronbach’s alpha coefficient and McDonald’s omega were used to estimate the instrument’s reliability. Forty-two Brazilian adolescents participated in the study (mean age: 16.0 ± 2.0 years; range: 13 to 19 years). Items that were difficult to understand were adapted to the context of Brazilian adolescents. Cronbach’s alpha coefficient and McDonald’s omega for the 21 items of the DHLI-BrA were, respectively, 0.79 and 0.80. Cronbach’s alpha coefficient for the subscales of the self-report instrument was 0.53-0.79 (range), demonstrating good reliability in the total instrument and moderate reliability in the subscales. This study provides the cross-cultural adapted version of the Digital Health Literacy Instrument (DHLI), which is an instrument for measuring digital Health literacy, for use in Brazilian adolescents (DHLI-BrA). crosscultural cross DHLI (DHLI Portuguesespeaking Portuguese speaking DHLIBrA.

ABSTRACT To investigate individual and contextual factors associated with seeking treatment for traumatic dental injuries. A cross-sectional study was conducted with 739 pairs of guardians and children. Guardians answered a questionnaire addressing sociodemographic characteristics, seeking treatment for a tooth injury in the child, and the Oral Health Literacy-Adult Questionnaire. Descriptive analysis and unadjusted and adjusted multilevel Poisson regression analysis (p<0.05). The prevalence of seeking treatment for traumatic dental injury was 44.7%. Sociodemographic variables associated were white skin of the child (PR = 1.30; 95% CI: 1.08-1.76), mother’s age older than 35 years (PR = 1.70; 95% CI: 1.50-1.90), married parents (PR = 1.93; 95% CI: 1.70-2.23), guardians with more than eight years of schooling (PR = 2.00; 95% CI: 1.76-2.23), with adequate oral health literacy (PR = 3.33; 95% CI: 3.01-3.62) and the daily use of electronic devices by the child (PR = 1.26; 95% CI: 1.02-1.50). On the contextual level, attending a private school (PR = 1.77; 95% CI: 1.02-3.05) and the number of primary care units with oral health teams in the school district (PR = 1.78; 95% CI: 1.12-2.38) remained associated. Among the children who suffered TDI, adequate oral health literacy on the part of the parents stood out among the factors associated with seeking treatment. injuries crosssectional cross sectional 73 characteristics LiteracyAdult Literacy Adult Questionnaire p<0.05. p005 p p<0.05 . 0 05 (p<0.05) 447 44 7 44.7% PR 1.30 130 1 30 95 CI 1.081.76, 108176 1.08 1.76 , 08 76 1.08-1.76) mothers mother s 3 1.70 170 70 1.501.90, 150190 1.50 1.90 50 90 1.50-1.90) 1.93 193 93 1.702.23, 170223 2.23 2 23 1.70-2.23) 2.00 200 00 1.762.23, 176223 1.76-2.23) 3.33 333 33 3.013.62 301362 3.01 3.62 01 62 3.01-3.62 1.26 126 26 1.021.50. 102150 1.02 02 1.02-1.50) level 1.77 177 77 1.023.05 102305 3.05 1.02-3.05 1.78 178 78 1.122.38 112238 1.12 2.38 12 38 1.12-2.38 TDI p00 p<0.0 (p<0.05 4 44.7 1.3 13 9 081 1.081.76 10817 108 1.0 176 1.7 1.08-1.76 17 501 1.501.90 15019 150 1.5 190 1.9 5 1.50-1.90 19 702 1.702.23 17022 223 2.2 1.70-2.23 2.0 20 762 1.762.23 17622 1.76-2.23 3.3 013 3.013.6 30136 301 3.0 362 3.6 6 3.01-3.6 1.2 021 1.021.50 10215 102 1.02-1.50 023 1.023.0 10230 305 1.02-3.0 122 1.122.3 11223 112 1.1 238 2.3 1.12-2.3 p0 p<0.

Resumo Investigar fatores individuais e contextuais associados à busca de tratamento para lesões dentárias traumáticas. Foi realizado um estudo transversal com 739 pares de responsáveis e crianças. Os responsáveis responderam a um questionário abordando características sociodemográficas, busca por tratamento para traumatismo dentário na criança e o Questionário de alfabetização em saúde bucal para adulto. Análise descritiva e análise de regressão de Poisson multinível não ajustada e ajustada (p<0,05) foram realizadas. A prevalência de busca de tratamento para lesão dentária traumática foi de 44,7%. As variáveis sociodemográficas associadas foram a pele branca da criança (RP = 1,30; IC 95%: 1,08-1,76), idade da mãe maior que 35 anos (RP = 1,70; IC 95%: 1,50-1,90), os responsáveis casados (RP = 1,93; IC 95%: 1,70-2,23), com mais de oito anos de estudo (RP = 2,00; IC 95%: 1,76-2,23), com alfabetização adequada em saúde bucal (RP = 2,00; IC 95%: 1,76-2,23) e uso diário de dispositivos eletrônicos pela criança (RP = 1,26; IC 95%: 1,02-1,50). No nível contextual, frequentar uma escola particular (PR = 1,77; IC 95%: 1,02-3,05) e a quantidade de unidades básicas de saúde com equipes de saúde bucal no distrito sanitário da escola (PR = 1,78; IC 95%: 1,12-2,38) permaneceram associados.

Abstract The aim of the present study was to investigate the impact of oral health literacy (OHL) on conceptions of care and behaviors related to COVID-19. The sample came from two preliminary cross-sectional studies that determined the level of OHL of parents/guardians of six-to-12-year-old children in two major Brazilian cities (Curitiba and Belo Horizonte). Functional OHL was measured using the Brazilian version of the Rapid Estimate of Adult Literacy in Dentistry (BREALD-30) and the Health Literacy Dental Scale (HeLD-14) for the evaluation of interactive OHL. Participants were recruited through e-mail, social media, and telephone contact. The questionnaire on conceptions of care and behaviors related to COVID-19 was created based on the guidelines of the World Health Organization. Two hundred nineteen individuals participated in the study. There was no significant difference in socioeconomic and demographic variables and in the medians of BREALD and HeLD-14 between the two cities (P>0.05). Higher levels of functional OHL were associated with an appropriate conception that individual care affects collective care (P=0.038), but with an inappropriate conception of seeking medical assistance in cases of mild symptoms (P=0.030). Higher levels of interactive OHL were related to social distancing behavior in the city of Curitiba (P=0.049) and in the overall sample (P=0.040). It is concluded that functional OHL was associated with two of the investigated conceptions about COVID-19, while interactive OHL was associated with social distancing behavior. These data may suggest that different dimensions of the OHL can have an impact on different aspects of coping with the pandemic. (OHL COVID19.

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.

Abstract The aim of the present study was to investigate predictors of malocclusion in Brazilian schoolchildren eight to ten years of age based on a causal directed acyclic graph model. A cross-sectional study was conducted with 739 schoolchildren eight to ten years of age. Parents/guardians provided information on sleep disorders of the child (Sleep Disturbance Scale for Children) and family characteristics (Family Adaptability and Cohesion Evaluation Scale). The diagnosis of malocclusion was performed by four trained examiners using the Dental Aesthetic Index. Control variables were selected using a directed acyclic graph. Descriptive analysis was performed, followed by robust logistic regression analysis for complex samples (α = 5%). The following variables were associated with malocclusion in the final model: sleep disorders (OR = 2.61; 95%CI: 2.43–2.86), mouth breathing (OR = 1.04; 95%CI: 1.02–1.99), non-nutritive sucking habits (OR = 2.45; 95%CI: 2.37–4.85), and obesity (OR = 1.54; 95%CI: 1.02–2.33). Sociodemographic characteristics, family functioning, and premature tooth loss did not remain associated with malocclusion.

ABSTRACT Background Sleep bruxism (BS) is defined as involuntary jaw movements characterized by grinding and clenching teeth. Objective To verify the association between chronotype, sleep quality, and self-reporting of BS in dental students. Method A cross-sectional study was conducted with 214 undergraduate dental students at a public university in northeast Brazil. The participants answered the Munich Chronotype Questionnaire for the identification of chronotype and another questionnaire regarding daily aspects to collect information about sleep quality, self-reported sleep bruxism, the use of sleeping pills, snoring, concentration during daily activities and energy upon waking. Results The prevalence of self-reported sleep bruxism was 11.0%. In the final model, the eveningness chronotype (OR = 23.00; 95% CI: 2.36-223.84, p = 0.007), habitual snoring (OR = 3.12; 95% CI: 1.31-7.39, p = 0.01) and low energy upon waking in the morning (OR = 2.37; 95% CI: 1.96-5.58, p = 0.040) were associated with self-reported sleep bruxism. Conclusion The evening chronotype, presence of snoring, and low energy when waking up in the morning influenced self-reporting of sleep bruxism among undergraduate dental students.

RESUMO Introdução O bruxismo do sono (BS) é definido como movimentos involuntários da mandíbula caracterizados por ranger e apertar os dentes. Objetivo Verificar se o cronotipo e a qualidade do sono estão associados ao autorrelato de BS em graduandos de Odontologia. Método Um estudo transversal com 214 estudantes de uma universidade pública do Nordeste do Brasil. Os participantes responderam ao Morningness-Eveningness Questionnaire para identificar os cronotipos e outro questionário sobre aspectos diários em que foram coletadas informações sobre qualidade do sono, autorrelato de bruxismo do sono, uso de pílulas para dormir, ronco, concentração nas atividades diárias, energia ao acordar. Resultados A prevalência de autorrelato do bruxismo do sono foi de 11,0%.

Abstract: The authors developed and validated a short form of the Brazilian Oral Health Literacy Assessment Task for Paediatric Dentistry (BOHLAT-P). Data included responses from 200 parents of preschoolers to sociodemographic and oral health service access questions on the BOHLAT-P, the Brazilian Rapid Estimate of Adult Literacy in Dentistry (BREALD-30), and the Brazilian Early Childhood Oral Health Impact Scale (B-ECOHIS). Data on the preschoolers’ dental caries experience (ICDAS-II) were also included. An item response theory-based approach was employed to develop the short form, while confirmatory factor analysis evaluated the instrument dimensionality. The validity and reliability of the short form were tested by statistical analysis using BREALD-30, B-ECOHIS, and sociodemographic and dental caries experience data. The short form (BOHLAT-P-30) comprises 30 items, is unidimensional, and presents better model fit estimates (TLI = 0.94; CFI = 0.94; RMSEA = 0.05) than those of the BOHLAT-P. Moreover, BOHLAT-P-30 demonstrated excellent reliability (Cronbach's alpha = 0.91; intraclass correlation coefficient [ICC] = 0.95). BOHLAT-P-30 scores were positively correlated with BREALD-30 scores (r = 0.71), with the number of years of schooling (r = 0.60), and with the number of hours spent reading (r = 0.33). BOHLAT-P-30 scores were negatively correlated with B-ECOHIS scores (r = -0.21), and with the number of teeth with cavitated caries (r = -0.18). After controlling for confounding factors, BOHLAT-P-30 scores were not found to be associated with caries presence, or with the number of teeth with cavitated caries. The BOHLAT-P-30 had properties similar to those of the BOHLAT-P, and proved to be a valid measure to assess the OHL of Brazilian parents.

Abstract Objective: To investigate the association between oral health problems and being ashamed of smiling or speaking among Brazilian adolescents. Material and Methods: This was a population-based cross-sectional study carried out with secondary data from 7,328 12-year-old Brazilian adolescents from the latest Brazilian national oral health survey (SB Brasil 2010). The question “In the previous 6 months, have you been ashamed of smiling or speaking due to your teeth?” was the outcome variable. Calibrated examiners performed clinical examinations on adolescents for the diagnosis of dental caries (DMF-T), dental trauma, dental fluorosis and occlusal alterations. Data were analyzed descriptively and by Poisson unadjusted and adjusted Poisson regression analysis (p<0.05). The final model was controlled by family income. Results: The prevalence of being ashamed of smiling or speaking was 13.6%. The following variables were associated with the outcome: female sex (PR= 1.33; 95% CI: 1.17-1.53), cavitated dental caries on upper incisors (PR= 1.81; 95% CI: 1.51-2.15), dental trauma (PR= 1.36; 95% CI:1.16-1.60), increased maxillary overjet (PR= 1.36; 95% CI:1.18-1.57), dental crowding (PR= 1.60; 95% CI:1.40-1.83), midline diastema (PR= 1.30; 95% CI:1.11-1.44), tooth loss (PR= 1.45; 95% CI:1.16-1.80), mild/questionable dental fluorosis (PR= 1.23; 95% CI:1.06-1.44) and moderate/severe dental fluorosis (PR= 1.67; 95% CI:1.15-2.44). Conclusion: Oral health problems that impact dental aesthetics were predisposing factors for being ashamed of smiling or speaking in Brazilian adolescents.

Abstract: Specific measures to evaluate positive oral health have been in a nascent stage in Dentistry, especially in developing countries. The present study aimed to translate, cross-culturally adapt and evaluate the psychometric properties of the Brazilian version of Positive Oral Health and Well-Being (B-POHW). After forward-backwards translation to Brazilian Portuguese language, the cross-cultural adaptation of B-POHW was pretested, followed by the main study to perform psychometric analysis. We tested the model fit by Confirmatory Factor Analysis with categorical factor indicators in bifactor and simple structure models on a sample of 209 participants (mean age: 39.36 ± 12.26. Questionnaires about sociodemographic status, self-reported oral health-related outcomes, and general well-being were administered and used as external validation measures. Moreover, dental caries experience was clinically diagnosed. For test-retest reliability, 53 participants completed the B-POHW a fortnight later. The following results were found: a) the bifactor model presented the best model fit; b) the B-POHW demonstrated satisfactory internal consistency (Cronbach's α and McDonald's ω > 0.8); c) the intraclass correlation coefficient suggested good reliability for the Global Factor of B-POHW in the test-retest (ICC = 0.84); d) evidence based on other variables and construct representation was in line with the positive oral health framework. The B-POHW is psychometrically sound to be used in a Brazilian context, and evidence of its internal structure confirmed its theoretical framework for measuring positive oral health. These findings advance in holistic approaches, enabling to assess positive oral health in Dental practice in Brazil.
