Resumo O objetivo do estudo foi avaliar a associação entre religiosidade e binge drinking no início da adolescência. Um estudo transversal realizado com adolescentes de 10 a 13 anos de Belo Horizonte, Brasil. Foi realizada uma amostragem aleatória estratificada considerando distrito administrativo e ano escolar. Os adolescentes preencheram um formulário com o AUDIT C, perguntas sobre religiosidade e perguntas sobre binge drinking pelos pais e melhor amigo. Um formulário sobre questões socioeconômicas foi respondido pelos responsáveis. Foi realizada análise descritiva, regressão logística univariada e multivariada. Participaram do estudo 650 adolescentes. A frequência de binge drinking foi de 13,7%. No modelo ajustado, a religiosidade não esteve associada ao binge drinking. As covariáveis associadas foram idade de 12-13 anos (OR: 1,94 IC95%: 1,06-3,56; p=0,030), binge drinking pela mãe (OR: 3,12; IC95%: 1,76-5,52; p<0,001) binge drinking pelo melhor amigo (OR: 6,01; IC95%: 3,40-10,62; p<0,001) e família não nuclear (OR: 1,80; IC95%: 1,01-3,23; p=0,045). Os achados revelaram que apesar dos adolescentes afirmarem serem religiosos, para o binge drinking, os principais fatores que influenciaram essa decisão foi o binge drinking pelo melhor amigo, mãe e família não nuclear.

Abstract This study evaluated the association between religiosity and binge drinking in early adolescence. A cross-sectional study was conducted with adolescents aged 10-13 from Belo Horizonte, Brazil. Stratified random sampling was performed considering the administrative district and school year. Adolescents filled an AUDIT-C form, containing questions about religiosity and binge drinking by parents and their best friends. Adolescents’ caregivers answered a form regarding socioeconomic issues. Descriptive analysis, univariate, and multivariate logistic regression were performed. A total of 650 adolescents participated in the study. The frequency of binge drinking was 13.7%. In the adjusted model, religiosity was not associated with binge drinking. The covariates associated were the age of 12-13 years (OR: 1.94; CI95%: 1.06-3.56; p=0.030), maternal binge drinking (OR: 3.12; CI95%: 1.76-5.52; p<0.001) best friend binge drinking (OR: 6.01; CI95%: 3.40-10.62; p<0.001) and nonnuclear family (OR: 1.80; CI95%: 1.01-3.23; p=0.045). The findings revealed that, for binge drinking, the main factors that influenced this decision were the best friend and maternal binge drinking and family structure, although the adolescents claimed to be religious.

Abstract: The aim of the present study was to evaluate the influence of socioeconomic factors, oral conditions and the impact of OHRQoL as possible risk indicators related to the incidence of untreated dental caries in preschool children two years after an initial examination. A prospective longitudinal study was performed with a sample of 288 preschool children allocated to two groups at baseline (T0): caries free (n = 144) and with untreated dental caries (n = 144). Untreated dental caries was determined through clinical examinations performed by a calibrated dentist at T0 (Kappa > 0,89) and T1 (two years after the baseline) (Kappa > 0,91) using the dmft criteria. Parents/caregivers answered a socioeconomic questionnaire and the Brazilian version of the Early Childhood Oral Health Impact Scale (B-ECOHIS) at T0 and T1. Mann-Whitney test and hierarchically adjusted Poisson regression models were used (95%CI, p < 0,05). The incidence of untreated dental caries was 41.3%. Low (RR = 1.63; 95%CI:1.18–2.26; p < 0.001) and high severity of untreated dental caries (RR = 1.92; 95%CI:1.36–2.72; p < 0.001), monthly household income less than two times the Brazilian minimum salary (RR = 1.79; 95%CI:1.04–3.25; p = 0.042) and overall B-ECOHIS score (RR = 1.03; 95%CI:1.02–1.05; p < 0.001) at T0 were risk indicators for the incidence of untreated dental caries among the preschool children. In conclusion, the incidence of untreated dental caries was high and the higher severity of untreated dental caries, the lower monthly income and the higher the B-ECOHIS score (indicating a negative impact on quality of life) were risk indicators to the developing of new lesions of untreated dental caries after 2 years.

Abstract The aim of the present study was to investigate the prevalence of oral health-related shame and the associated factors among 8-to-10-year-old Brazilian schoolchildren. A cross-sectional study was conducted with 388 children randomly selected from public and private schools of Diamantina, southeastern Brazil. In order to identify the feeling of shame, self-reports were collected through a single question, “In the last month, did you feel ashamed because of your teeth or mouth? Two calibrated examiners performed the clinical examination for dental caries (DMFT/dmft index), traumatic dental injuries (O’ Brien), and malocclusion (Dental Aesthetic Index). Sociodemographic indicators were obtained through a questionnaire answered by the children’s caregivers. Descriptive analysis, chi-square test, and hierarchical Poisson regression models were performed (95%CI; p < 0.05). The prevalence of shame was 38.1% (n = 148). The adjusted regression analysis demonstrated a significant association between shame and untreated dental caries (PR: 1.34; 95%CI: 1.04–1.74; p = 0.02), age of 10 years (PR: 1.36; 95%CI: 1.05–1.76; p = 0.01), and with parents with less than eight years of schooling (PR: 1.30; 95%CI: 1.00–1.68; p = 0.04). Older children with untreated dental caries and whose parents had lower education level presented a higher prevalence of oral health-related shame.

Abstract The present study aimed to evaluate the frequency of immediate care seeking after traumatic dental injury (TDI) in primary dentition and its association with the children’s characteristics, socioeconomic status, and TDI characteristics. This was a cross-sectional study with dental records of children aged 9 months to 6 years who attended a reference center in TDI in primary dentition between 2007 and 2018. Immediate care seeking after TDI, child’s characteristics, sociodemographic conditions and TDI characteristics were collected. Descriptive statistics and Poisson regression analysis with robust variance were performed (p < 0.05; 95%CI). Among the 493 dental records, 61.1% (n = 301) were of males and 50.5% (n = 249) were from children aged 2 years or less. More than one third of the sample (36.9%; n = 182) sought immediate care after TDI. Among the types of TDI, the prevalence of soft tissue injuries was 59.0% (n = 291), while 51.7% (n = 255) were hard tissue injuries and 54.0% (n = 266) were supporting tissue injuries. Immediate care seeking after TDI was higher in children who needed suture (PR: 1.39; 95%CI: 1.01–1.92. p = 0.039), had luxation (lateral, intrusion, or extrusion) (PR: 2.36; 95%CI: 1.36–4.08. p = 0.002) or avulsion (PR: 2.18; 95%CI: 1.28–3.70. p = 0.004). The need for suture, luxation (lateral, intrusion and extrusion), and avulsion were determinant factors for the immediate care seeking after TDI, regardless of the child’s characteristics and socioeconomic status.

Abstract The aim of the present study was to determine the concentration of total fluoride (TF) and total soluble fluoride (TSF) in children’s dentifrices marketed in the city of Lima, Peru. Three samples of 23 dentifrices (4 without fluoride and 19 with fluoride) were purchased in different pharmacies in Lima, Peru. The TF and TSF concentrations found in the dentifrices were determined by ion-selective electrode, expressed in ppm F (μg F/g of dentifrice). The TF concentration in the majority of the fluoride toothpastes matched that shown on the label, except for one declared as 1450 ppm F by the manufacturer, whereas only 515.1 ppm F was found. The concentration of TSF found in the fluoride toothpastes ranged from 457.5 to 1134.8 ppm F. All the dentifrices were formulated with silica, but one also presented calcium carbonate. In conclusion, 83% of the children’s dentifrices marketed in Lima, Peru, were fluoridated, but only 53% contained a TSF concentration greater than 1000 ppm F, the minimum concentration required to provide an anticaries effect.

Resumo: Propomos apresentar um breve estudo do discurso de Elomar Figueira Mello – compositor, intérprete e violonista, que tem como fonte de inspiração o espaço, a cultura e o povo do sertão – através da aplicação do conceito de paratopia na constituição dos ethé nas cenografias dos textos. Para tanto, apresentaremos a análise do plano textual de duas canções intituladas “O violeiro” e “Campo branco”, em que podem ser observados elementos que configuram o caráter paratópico da obra literomusical de Elomar. O objetivo principal do artigo consiste em verificar como a paratopia, observada no investimento ético do plano verbal das canções, é um dos fatores constitutivos na demarcação do posicionamento do compositor no campo literomusical brasileiro.

Abstract: The litero-musical discourse in the work of the composer, guitarist, poet and singer Elomar Figueira Mello is investigated in the framework of the theory of the Discourse Analysis, in which we consider the aspects related to the concepts of paratopia and ethos. The work of Figueira Mello is funded on the colonial Brazil of the 17th century and, in particular, he brings back the language, the music and the environment of that time, with the objective of value the Brazilian culture. We analyze two of the most relevant pieces of the composer, namely “O violeiro” and “Campo Branco”, in which we have found strong paratopic marks, which characterizes this positioning in the Brazilian litero-musical scenario.

ABSTRACT: Temporomandibular joint disorders (TMD) are multifactorial pathological conditions that can generate significant impacts on quality of life of individuals. Orthodontics treatments have been discussed in the current literature due to its possible association with the development of TMD. The aim of this study was to evaluate the relationship between the use of fixed orthodontic appliances and the symptoms of TMD. This cross-sectional study was performed with a sample of 336 undergraduate dental students that answered a structured questionnaire about symptoms of TMD. The sample was paired for sex and use of fixed orthodontic appliances. The results highlighted that the most prevalent symptoms of TMD were headaches (21.4 %, n=72), temporomandibular joint noises (21.4 %, n=72) and head and/or neck pain (20.0 %, n=67). The most of sample, 60.4 % (n=203), showed mild TMD symptomatology. No statistical association was observed between the use of orthodontic appliances and TMD symptoms (p=0.121). It can be suggested that the use of fixed orthodontic appliances is not a factor associated with the symptoms of TMD. Still, it is possible to conclude that the prevalence of light TMD symptoms in dentistry students is high.

RESUMEN: Los trastornos de la articulación temporomandibular (TTM) son un grupo de patologías multifactoriales que pueden generar impactos significativos en la calidad de vida de las personas. Los tratamientos de ortodoncia se han discutido en la literatura actual debido a su posible asociación con el desarrollo de TTM. Evaluar la relación entre el uso de aparatos de ortodoncia fijos y los síntomas de TTM. Material y métodos: este estudio transversal se realizó con una muestra de 336 estudiantes de odontología que respondieron un cuestionario estructurado sobre los síntomas de TTM. La muestra fue emparejada por género y uso de aparatos de ortodoncia fijos. Los resultados destacaron que los síntomas más prevalentes de TTM fueron cefaleas (21,4 %, n=72), ruidos de la articulación temporomandibular (21,4 %, n=72) y dolor de cabeza y/o cuello (20,0 %, n=67). La mayor parte de la muestra, 60,4 % (n=203), presentó síntomas leves de TTM. No se observó asociación estadística entre el uso de aparatos de ortodoncia y los síntomas de TTM (p=0,121). Se puede sugerir que el uso de aparatos de ortodoncia fijos no es un factor asociado con los síntomas de TTM. Aun así, es posible concluir que la prevalencia de síntomas leves de TTM en estudiantes de odontología es alta.

Objetivo: o objetivo do presente estudo foi avaliar a associação entre as alterações oronasofaríngeas e as más oclusões (mordida aberta anterior e mordida cruzada posterior) em pré-escolares. Métodos: um estudo transversal foi conduzido com uma amostra representativa de 732 pré-escolares com 3 a 5 anos de idade, aleatoriamente selecionados em pré-escolas privadas e públicas. A mordida aberta anterior (MAA) e a mordida cruzada posterior (MCP) foram avaliadas a partir de exames clínicos. Pais/cuidadores responderam a um questionário relativo a indicadores sociodemográficos e problemas oronasofaríngeos. A análise estatística envolveu análise descritiva e regressão de Poisson (p < 0,05). Resultados: as prevalências de MAA e MCP foram de 21,0% e 11,6%, respectivamente. Ter três anos de idade (RP = 1,244; IC = 1,110 - 1,394; p < 0,001, considerando-se RP = Razões de Prevalência e IC = Intervalo de Confiança 95%), ter quatro anos de idade (RP = 1,144; IC = 1,110 - 1,394; p = 0,015), ausência de alergia (RP = 1,158; IC = 1,057 - 1,269; p = 0,002), não ter se submetido a cirurgias do nariz (RP = 1,152; IC = 1,041 - 1,275; p = 0,006) e ter tido dor de garganta mais de cinco vezes no mesmo ano (RP = 1,118; IC = 1,011 - 1,237; p = 0,030) foram significativamente associados com MAA. Ausência de asma (RP = 1,082; IC = 1,012 - 1,156; p = 0,020), não ter realizado adenoidectomia (RP = 1,112; IC = 1,068 - 1,158; p < 0,001) e não ter se submetido a cirurgias do nariz (RP = 1,114; IC = 1,069 - 1,160; p < 0,001) permaneceram associados à MCP. Conclusão: associações significativas foram encontradas entre as alterações oronasofaríngeas relatadas e a presença de MAA e MCP em pré-escolares.

Abstract Objective: Evidence is contradictory regarding the association between oronasopharyngeal abnormalities and malocclusion. The aim of the present study was to assess the association between oronasopharyngeal abnormalities and malocclusion (anterior open bite and posterior crossbite) in preschoolers. Methods: A cross-sectional study was conducted with a representative sample of 732 preschoolers aged 3-5 years old selected randomly from private and public preschools. Anterior open bite (AOB) and posterior crossbite (PC) were evaluated through a clinical exam. Parents/caregivers answered a questionnaire addressing sociodemographic indicators and oronasopharyngeal issues. Statistical analysis involved descriptive analysis and Poisson regression (p < 0.05). Results: The prevalences of AOB and PC were 21.0% and 11.6%, respectively. Being three years old (PR = 1.244; 95% CI = 1.110-1.394; p < 0.001), being four years old (PR = 1.144; 95% CI = 1.110 - 1.394; p = 0.015), absence of allergy (PR = 1.158; 95% CI = 1.057 - 1.269; p = 0.002), not having undergone nose surgery (PR = 1.152; 95% CI = 1.041 - 1.275; p = 0.006) and having a sore throat more than five times in the same year (PR = 1.118; 95% CI = 1.011 - 1.237; p = 0.030) were significantly associated with AOB. The absence of asthma (PR = 1.082; 95% CI = 1.012 - 1.156; p = 0.020), not having undergone throat surgery (PR = 1.112; 95% CI = 1.068 - 1.158; p < 0.001) and not having undergone nose surgery (PR = 1.114; 95% CI = 1.069 - 1.160; p < 0.001) remained associated with PC. Conclusion: Significant associations were found between oronasopharyngeal-reported abnormalities and the presence of AOB and PC in preschoolers.

Abstract The aim of this study was to evaluate the impact of dental caries, traumatic dental injuries (TDI), toothaches, and malocclusion on the oral health-related quality of life (OHRQoL) of the families of Brazilian preschool children. A population-based, matched case-control study involving 415 pre-schoolers aged 3–5 years was conducted. The case (impact on OHRQoL) and control groups (no impact on OHRQoL) were matched for age, gender, and family income at an 1:4 ratio. Impact on the OHRQoL of a family was assessed using the Brazilian version of the Early Childhood Oral Health Impact Scale (B-ECOHIS). Dental caries, TDI, and malocclusion were diagnosed by three calibrated dentists (Kappa: 0.85–0.90). Data analysis involved descriptive statistics and conditional logistic regression analysis (p ≤ 0.05; 95%CI). There were no differences between the cases and controls regarding age, gender, and family income (p > 0.05). The most frequent responses on the B-ECOHIS among cases were “felt guilty” (68.6%) and “been upset” (48.2%). The following variables were significantly associated with negative impacts on family OHRQoL (cases): caries severity (OR = 6.680; 95%CI = 2.731–16.349), a history of toothache (OR = 2.666; 95%CI = 1.492–4.765), parental rating of the child’s oral health as poor (OR: 1.973; 95%CI = 1.072–3.634), and parent’s/caregiver’s age (OR = 2.936; 95%CI = 1.077–3.478). Anterior open bite was positively associated with OHRQoL (OR = 4.050; 95%CI = 1.333–12.314). Caries severity, a history of toothache, parental rating of the child’s oral health as poor, and younger parents/caregivers were associated with impact on the OHRQoL of the families of preschoolers.

OBJETIVO: o objetivo dessa revisão sistemática foi verificar se existem evidências científicas que comprovam a efetividade da TMO como agente coadjuvante do tratamento ortodôntico de indivíduos com distúrbios orofaciais. Além disso, avaliar a qualidade metodológica dos estudos incluídos nessa revisão. MÉTODOS: uma busca eletrônica foi realizada em 8 bases de dados (MEDLINE, BBO, LILACS, Web of Science, EMBASE, BIREME, Cochrane Library e Scielo), sem restrição de idioma. A busca foi realizada com artigos publicados no período compreendido entre janeiro de 1965 a março de 2011. A seleção dos artigos e extração dos dados foi realizada por dois revisores independentes. Avaliação da qualidade dos artigos também foi realizada. RESULTADOS: a estratégia de busca resultou em 355 publicações. Após seleção baseada nos critérios de elegibilidade, quatro artigos foram qualificados para análise final. A todos os artigos incluídos nessa revisão foram atribuídos um alto risco de viés. CONCLUSÇÕES: os resultados do presente estudo demonstram a escassez de estudos consistentes e de evidências científicas que indicam a utilização da TMO em associação ao tratamento ortodôntico com a finalidade de promover melhores resultados na correção de desordens dentofaciais em indivíduos com distúrbios orofaciais.

OBJECTIVE: The aim of the present systematic review was to determine the existence of scientific evidence demonstrating the effectiveness of orofacial myofunctional therapy (OMT) as an adjuvant to orthodontic treatment in individuals with orofacial disorders. A further aim was to assess the methodological quality of the studies included in the review. METHODS: An electronic search was performed in eight databases (Medline, BBO, LILACS, Web of Science, EMBASE, BIREME, Cochrane Library and SciELO) for papers published between January 1965 and March 2011, with no language restrictions. Selection of articles and data extraction were performed by two independent researchers. The quality of the selected articles was also assessed. RESULTS: Search strategy resulted in the retrieval of 355 publications, only four of which fulfilled the eligibility criteria and qualified for final analysis. All papers selected had a high risk of bias. CONCLUSIONS: The findings of the present systematic review demonstrate the scarcity of consistent studies and scientific evidence supporting the use of OMT in combination with orthodontic treatment to achieve better results in the correction of dentofacial disorders in individuals with orofacial abnormalities.

OBJETIVO: investigar os fatores determinantes do desconforto atribuído ao uso do aparelho ortodôntico fixo e sua influência na qualidade de vida de adolescentes. MÉTODOS: participaram desse estudo transversal 272 indivíduos, com idades entre 9 e 18 anos, estudantes de escolas públicas e privadas, que usavam aparelhos ortodônticos fixos (braquetes). Os participantes foram selecionados aleatoriamente, entre 62.496 indivíduos da mesma faixa etária. A coleta de dados foi feita em forma de entrevista e questionário. A intensidade do desconforto e variáveis biopsicossociais foram avaliadas por meio do Oral Impact on Daily Performance (OIDP). A autoestima foi determinada pela Global Negative Self-Evaluation (GSE). A análise estatística envolveu o teste qui-quadrado e a análise de regressão de Poisson, simples e múltipla. RESULTADOS: embora a maioria dos indivíduos não apresentasse desconforto, observou-se uma prevalência de impacto na vida diária devido, exclusivamente, ao uso do aparelho ortodôntico fixo, de 15,9%. Variáveis idade de 15 a 18 anos [RP = 3,2 (IC 95% = 1,2-8,5)], dificuldade de falar [RP = 2,2 (IC 95% = 1,1-4,6)], dificuldade de limpar a boca [RP = 2,4 (IC95% = 1,2-4,8)] e mobilidade dos dentes [RP = 3,9 (IC 95% = 1,8-8,1)] permaneceram associadas, de forma independente, à maior prevalência de desconforto (p ≤ 05). CONCLUSÕES: desconforto associado ao uso de aparelhos ortodônticos fixos influenciou negativamente a qualidade de vida de adolescentes. Os fatores determinantes foram idade, dificuldade de limpar a boca, de falar e mobilidade dentária.

OBJECTIVE: To investigate the determinant factors of discomfort attributed to the use of fixed orthodontic appliance and the effect on the quality of life of adolescents. MATERIAL AND METHODS : Two hundred and seventy-two individuals aged between 9 and 18 years old, enrolled in public and private schools and undergoing orthodontic treatment with fixed appliance participated in this cross-sectional study. The participants were randomly selected from a sample comprising 62,496 individuals of the same age group. Data was collected by means of questionnaires and an interview. Discomfort intensity and bio-psychosocial variables were assessed using the Oral Impact on Daily Performance questionnaire. Self-esteem was determined using the Global Negative Self-Evaluation questionnaire. Statistical analysis involved the chi-square test and both simple and multiple Poisson regression analyses. RESULTS: Although most individuals did not present discomfort, there was a prevalence of 15.9% of impact on individuals' daily life exclusively due to the use of fixed orthodontic appliance . Age [PR: 3.2 (95% CI: 1.2-8.5)], speech impairment [PR: 2.2 (95% CI: 1.1-4.6)], poor oral hygiene [PR: 2.4 (95% CI: 1.2-4.8)] and tooth mobility [PR: 3.9 (95% CI: 1.8-8.1)] remained independently associated with a greater prevalence of discomfort (P ≤ 0.05). CONCLUSIONS: Discomfort associated with the use of fixed orthodontic appliances exerted a negative influence on the quality of life of the adolescents comprising the present study. The determinants of this association were age, poor oral hygiene, speech impairment and tooth mobility.

The objective of this study was to evaluate prediction factors for failure to seek treatment following a traumatic dental injury (TDI) to primary teeth among preschool children in the city of Campina Grande, Brazil. A cross-sectional study was carried out involving 277 children 3 to 5 years of age, with TDI, enrolled in public and private preschools. Parents filled out a form addressing demographic data and whether or not they had sought treatment. Clinical examinations were performed by three dentists who had undergone a calibration exercise (Kappa: 0.85 to 0.90) for the evaluation of TDI. Bivariate and multivariate Poisson regression models were constructed (α = 5%). Enamel fracture was the most prevalent type of TDI (48.7%) and the upper central incisors were the most affected teeth (88.4%). The frequency of seeking dental treatment was low (9.7%). The following variables were associated with failure to seek treatment following TDI: a household income greater than one minimum wage (PR = 1.170; 95%CI 1.018-1.341), parents/caregivers’ perception of a child’s oral health as poor (PR = 1.100; 95%CI 1.026-1.176), and the non-perception of TDI by parents/caregivers (PR = 1.250; 95%CI 1.142-1.360). In the present study, the frequency of seeking treatment following TDI was low, and parents/caregivers with a higher income, a poor perception of their child’s oral health and a lack of awareness regarding the trauma were more likely to fail to seek treatment following TDI to primary teeth.

The present study was designed to evaluate associations between developmental defects of enamel (DDE) in the primary dentition and aspects related to mothers and preschoolers in the city of Diamantina, Brazil. A case-control study was carried out involving children aged three to five years. The case group was composed of 104 children with at least one dental surface affected by DDE. The control group comprised 105 children without DDE, matched for gender and age. The diagnosis of enamel defects was performed using the Developmental Defects of Enamel Index. Information was collected through interviews investigating socio-demographic aspects, gestation, birth weight, prematurity and breastfeeding. Simple and multiple regression analyses were performed, providing unadjusted and adjusted prevalence ratios (Poisson regression). DDE were more prevalent among children who had not been breastfed (PR = 1.57; 95% CI: 1.1-2.2) and those whose mothers were under 24 years of age at the birth of the child (PR = 1.41; 95% CI: 1.1-1.9). The prevalence of DDE in the primary dentition was higher among children who had not been breastfed and those whose mothers were under 24 years of age at the birth of the child.

The aim of this study was to assess the prevalence of early childhood caries (ECC) in children and investigate the influence of sociodemographic variables, quality of oral hygiene and child-related aspects. A cross-sectional study was carried out with 593 children aged three to five years. Data were collected through clinical examinations and interviews with parents. Interviews with parents of the children were conducted to acquire information on sociodemographic aspects, breastfeeding, bottle feeding and harmful oral habits. Statistical analysis involved the chi-square test and the Poisson regression. The prevalence of ECC was 53.6%. The occurrence of ECC was greater among children with unsatisfactory oral hygiene (PR: 2.95; 95% CI: 2.42-3.60) and those from a family with a lower monthly household income (PR: 1.62; 95% CI: 1.24-2.10). In conclusion, unsatisfactory oral hygiene and monthly income exerted an influence on the occurrence of ECC among preschoolers.
