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.

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. Entre as crianças que sofreram TDI, a alfabetização em saúde bucal adequada dos pais foi um fator que se destacou na busca por tratamento.

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.

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. Sleep disorders, mouth breathing, sucking habits, and obesity are predictors of malocclusion in schoolchildren eight to ten years of age.

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.

Abstract This study outlines the profile of research productivity grant holders of the Conselho Nacional de Desenvolvimento Científico e Tecnológico [CNPq (National Council for Scientific and Technological Development)] in the field of pediatric dentistry. A cross-sectional study with data collected from the Brazilian academic curriculum vitae database. The eligibility criterion was being a research productivity grant holder in pediatric dentistry from 2018 to 2020. In the period of interest, 215 individuals were research productivity grant holders in the field of dentistry, 33 of whom had graduate degrees (specialization, master's or doctorate) in pediatric dentistry. The period of scientific production and work concluded of advising of scientific initiation, master, doctoral and post-doctoral degrees was 2010 to 2020. Descriptive analysis was performed and the Kruskal-Wallis test was used to analyze associations (5% significance level) between productivity grant level (2, 1D, 1C, 1B or 1A) and year of obtainment of the doctoral degree. The VOSviewer (version 1.6.17) was used to present graphically the interinstitutional collaborations. The sample was composed of Level 2 researchers (66.7%), women (66.7%), researchers linked to institutions in the southeastern region of Brazil (81.8%), with a doctoral degree concluded prior to 2002 (51.5%), began working as a professor at a higher education institution prior to 2007 (78.8%) and the title of full professor (45.5%). No significant association was found between productivity grant level and year of conclusion of the doctoral degree (p = 0.10). Median (interquartile range) of scientific articles was 119 (37-312). The prevalence of citations (57.52%) and JCR articles (62.76%) was higher among female researchers. In conclusion, CNPq research productivity grant holders in pediatric dentistry are essentially represented by females from the southeast region of the country (UFMG and USP). However, males have proportionally greater productivity.

Abstract: This study aimed to determine the impact of the COVID-19 pandemic on sleep quality and possible sleep bruxism (SB) in children eight to ten years of age. The study hypothesis was that sleep disturbances influenced a higher occurrence of bruxism during the COVID-19 pandemic. A longitudinal study was conducted at two time points: in person prior to the COVID-19 pandemic (T1), and online during the pandemic (T2). The sample comprised 105 children. Parents/caregivers answered a questionnaire addressing sociodemographic characteristics, the use of electronic devices, reported (vs. clinical) SB, and the Sleep Disturbance Scale for Children (SDSC) at both T1 and T2. McNemar’s and Wilcoxon’s tests were used to compare SB and sleep disorders at both time points. Poisson regression analysis determined the relative risk (RR) among the variables, and the incidence of possible SB (p≤0.05). The comparison of the two time points (T1 and T2) revealed a significant increase in possible SB (p<0.01) and sleep disorders (p < 0.04). Children whose parents had a lower schooling level (RR: 2.67; 95%CI: 1.19–6.01), those with their own electronic devices (RR: 1.97; 95%CI: 1.09–2.50), and those with sleep disorders during the pandemic (RR: 1.74; 95%CI: 1.35–2.24) were at greater risk of developing SB during the pandemic. Moreover, the incidence of bruxism and sleep disorders was greater during the pandemic. The factors influencing SB incidence during the pandemic were a lower level of mothers’ schooling, greater access to electronic devices, and the occurrence of sleep disorders.

Abstract The aim of the present study was to investigate whether possible awake bruxism (AB) is associated with the use of electronic devices and the practice of sports in schoolchildren aged eight to ten years. A cross-sectional study was conducted with 739 students in public and private schools in the city of Campina Grande, Brazil. Parents/guardians answered a questionnaire addressing sociodemographic data. The children answered questions about use of electronic devices, practice of sports, and AB. Statistical analysis involved robust logistic regression for complex samples (α = 5%). The prevalence of possible AB was 14.9%. Being female (OR = 1.71, 95%CI: 1.11–2.63), being the middle child (OR = 2.19, 95%CI: 1.14–3.88), having unmarried parents (OR = 1.73, 95%CI: 1.13–2.65), daily use of a cell phone/tablet/computer (OR = 1.82, 95%CI: 1.19–2.80), use of electronic devices for two or more hours per day (OR = 1.97, 95%CI: 1.35–2.86), and playing sports in and/or out of school (OR = 1.60, 95%CI: 1.18–2.52) remained associated with possible AB in the final model. The presence of possible AB was influenced by the use of electronic devices and the practice of sports among schoolchildren aged eight to ten years.

ABSTRACT OBJECTIVE To investigate whether oral health literacy (OHL) and school context are associated with untreated dental caries on the anterior teeth of adolescents. METHODS A representative cross-sectional study was conducted with 746 students aging 15 to 19 in the city of Campina Grande, Brazil. The guardians answered a questionnaire addressing sociodemographic data and the absence/presence of private health insurance. Two examiners were trained for the diagnosis of dental caries using the Nyvad criteria and the measurement of OHL using the Brazilian Rapid Estimate of Adult Literacy in Dentistry (BREALD-30) (Kappa > 0.80). Contextual aspects of the schools were obtained from the 2017 National School Census. Descriptive statistics were conducted, followed by unadjusted and adjusted robust negative binomial regression for complex samples (p < 0.05). RESULTS The average number of anterior teeth with untreated caries was 0.95 (SD = 1.77). Among individual factors, the male sex (RR = 1.64; 95%CI: 1.24–2.16), inadequate level of OHL (RR = 2.03; 95%CI: 1.13–1.63), marginal level of OHL (RR = 1.87; 95%CI: 1.05–3.33) and not having private health insurance (RR = 1.34; 95%CI: 1.07–1.68) were associated with untreated caries on anterior teeth. Among school contextual factors, the number of students in the classroom (RR = 2.64; 95%CI: 1.78–3.93), number of public oral health services in the district (RR = 0.14; 95%CI: 0.05–0.39) and average income of the district in which the school is located (RR = 0.99; 95%CI: 0.98–0.99) were associated with the outcome. CONCLUSIONS Sociodemographic factors, having private health insurance, OHL, and school context exerted an influence on the occurrence of untreated dental caries on anterior teeth in adolescents aging 15 to 19.

Abstract The aim of this study was to evaluate the association between number of cavitated dental caries in adolescents and family cohesion, drug use, sociodemographic factors and visits to the dentist. A cross-sectional study was conducted with 746 adolescents aged 15 to 19 years from Campina Grande, Brazil. The parents answered a questionnaire addressing sociodemographic data, and the adolescents answered questionnaires on drug use, type of family cohesion and visits to the dentist. Two examiners underwent training and calibration exercises (K > 0.80) to diagnose dental caries using the Nyvad criteria. A directed acyclic graph was created to select the variables to be controlled in the statistical model. Associations between the independent variables and the outcome were determined using robust Poisson Regression analysis for complex samples (α = 5%). Rate ratios (RR) and 95% confidence intervals (CI) were calculated. The prevalence of dental caries and cavitated lesions among the adolescents was 92.8% and 41.6%, respectively. The following variables remained associated with the number of cavitated lesions in the multivariate analysis: disengaged (RR: 6.30; 95%CI: 1.24–31.88; p = 0.028 ), separated (RR: 4.80; 95%CI: 1.03–22.35; p = 0.046) and connected (RR: 5.23; 95%CI: 1.27–21.59; p = 0.024) levels of family cohesion, and high social class (RR: 0.55; 95%CI: 0.39–0.76; p = 0.001). In conclusion, this paper posits that adolescents with a lower socioeconomic status, and those whose family cohesion was classified as disengaged, separated or connected, had a larger number of cavitated lesions.

ABSTRACT OBJECTIVE To evaluate the psychometric properties of the Brazilian Portuguese version of the Rapid Estimate of Adult Literacy in Dentistry (BREALD-30) administered to adolescents. METHODS The study included 750 adolescents: 375 aged 12 years and 375 aged 15–19 years, attending public and private schools in Campina Grande, state of Paraíba, Brazil, in 2017. Reliability was measured based on internal consistency and test-retest reliability. Convergent validity was measured based on correlations between BREALD-30 and Functional Literacy Indicator scores. Divergent validity was measured by comparing BREALD-30 scores with sociodemographic variables. For predictive validity, the association between BREALD-30 scores and the presence of cavitated carious lesions was tested using a multiple logistic regression model. All statistical tests were performed with a significance level of 5%. RESULTS BREALD-30 showed good internal consistency for the 12 year olds and 15 to19 year olds (Cronbach’s alpha = 0.871 and 0.834, respectively) and good test-retest reliability [intraclass correlation coefficient (ICC) = 0.898 and 0.974; kappa = 0.804 and 0.808, respectively]. Moreover, item-total correlation was satisfactory for all items. BREALD-30 had convergent validity with the Functional Literacy Indicator for 12 year olds (rs = 0.558, p < 0.001) and for 15 to 19 year olds (rs = 0.652, p < 0.001). Participants with higher oral health literacy levels who attended private schools (p < 0.001), belonged to economic classes A and B2 (p < 0.001), and who had parents with higher education levels (p < 0.001) were included, indicating the divergent validity of the BREALD-30. Participants with lower BREALD-30 scores were more likely to have cavitated carious lesions [12 year olds: odds ratio (OR) = 2.37; 95% confidence interval (95%CI): 1.48–3.80; 15 to 19 year olds: OR = 1.96; 95%CI 1.24–3.11]. CONCLUSIONS BREALD-30 shows satisfactory psychometric properties for use on Brazilian adolescents and can be applied as a fast, simple, and reliable measure of oral health literacy.

ABSTRACT Objective: To verify the prevalence and association of parents’ and children’s anxiety concerning socioeconomic variables and child’s behavior during dental care. Methods: This was a quantitative, observational, transversal and descriptive study. Data collection was performed through a questionnaire aiming at sociodemographic data and dental experience as well as Venham Picture Test, Corah Dental Anxiety Scales and Frankl Anxiety Scale. Data were analyzed using descriptive and inferential statistics (Chi-square and Fisher’s exact test), α = 0.05. Results: The sample consisted of 7 to 9 year- old children (57.9%.), of whom 72.6% were submitted to invasive procedures. The prevalence of anxiety among children was 43.2% (n = 41). Regarding parents / guardians, the prevalence of anxiety was 88.4% (n = 84). A significant association was found between the dental appointment experience and the child’s anxiety (p = 0.050) using the VPT. A significant association between anxiety and the type of dental procedure (p = 0.017) as well as the child’s experience (p = 0.000) using the Frankl scale. Conclusion: There was no association between anxiety and socioeconomic variables. In the variables related to dental experiences, a significant association was found between the experience of the dental appointment and the anxiety of the child using the VPT scale. An association between anxiety and the type of procedure was observed, as well as dental appointment experience, using Frankl scale.

Methods A cross-sectional study conducted with a representative sample of 398 students in public university. The students answered a questionnaire validated for the evaluation of drug use and socio-demographic data. Poisson regression analysis was performed. Results A total of 56.3% and 13.3% of the students had used both legal and ilegal drugs. The following variables remained significantly associated with legal drug use in the final model: male sex (PR=1.48; 95%CI: 1.25-1.76), older age group (PR=1.23; 95%CI: 1.03-1.47), not living with parents (PR=1.20; 95%CI: 1.01-1.41), not having a religion (PR=1.37; 95%CI: 1.16-1.62) and taking a course in the health field (PR=1.33; 95%CI: 1.08-1.64). The following variables were significantly associated with ilegal drug use: male sex (PR=2.33; 95%CI: 1.35-4.02), older age group (PR=2.27; 95%CI: 1.28-4.02), higher monthly income (PR=1.73; 95%CI: 1.05-2.85) and not having a religion (PR=1.70; 95%CI: 1.02-2.84). Conclusion Legal and ilegal drug use at least once in life was associated with social factors, sex, age, income, religion, living situation and type of higher education course.

ABSTRACT: The objectives of this study were to analyze the results of articles retrieved on the subject of mouth neoplasms and mouth rehabilitation, published between 1990 and April 2016, identify the dispersion of the publications, and examine authorship patterns and citations in the Scopus database, based on the Laws of Bradford and Lotka. This was a bibliometric study, with a descriptive and quantitative approach. An analysis of articles published in journals indexed in the Scopus database was performed, using the terms “Mouth Neoplasms” and “Mouth Rehabilitation”. Twenty-eight original articles were retrieved, published in 18 journals, with irregular distribution in the period studied. At the time of analysis, 222 citations were identified with a mean of eight per document. The fields of medicine and dentistry stood out with publications on the theme. Germany had the largest scientific production. The study revealed a modest number of publications and the need for nursing engagement in this area of research.
