Resumo Introdução: Embora a utilização de Marcadores de Consumo Alimentar esteja prevista na atenção primária à saúde, seu uso pelas equipes de saúde bucal ainda é incipiente. Objetivo: Analisar a associação do consumo de alimentos cariogênicos, avaliado através de marcadores do consumo alimentar, com a ocorrência de cárie dentária não tratada em pré-escolares. Método: Envolveu 432 crianças (18-36 meses) em uma amostra representativa dos Centros Municipais de Educação Infantil (São José dos Pinhais-PR). Os pais/responsáveis responderam um questionário socioeconômico e demográfico, e as crianças foram avaliadas por examinadora calibrada (Kappa=0,80). O consumo de alimentos cariogênicos foi mensurado através do instrumento Marcadores de Consumo Alimentar (Ministério da Saúde; Brasil). O escore de consumo de alimentos cariogênicos (EAC) foi obtido pela soma de relatos de consumo de alimentos com açúcar livre. Resultados: A prevalência de cárie dentária não tratada foi 21% (IC95% 17–24). Na regressão múltipla de Poisson com variância robusta, a maior prevalência de cárie dentária não tratada foi associada ao maior EAC (RPa=1,16; IC95% 1,01–1,34; p=0,035), a maior idade das crianças (RPa=1,05; IC95% 1.01–1.10; p=0,021) e inversamente a maior escolaridade dos responsáveis (RPa=0,62; IC95% 0,42–0,92; p=0,017). Conclusão: O consumo de alimentos cariogênicos, medido através do Marcadores de Consumo Alimentar, foi associado com uma maior prevalência de cárie dentária não tratada em pré-escolares.

Abstract Background: Although the use of Food Consumption Markers is foreseen in primary health care, their use by oral health teams is still incipient. Objective: The objective of this study was to investigate the association of cariogenic food consumption, measured through the food consumption markers, with the occurrence of untreated dental caries in preschoolers. Method: The study included 432 children (aged 18–36 months) in a representative sample of the Municipal Centers for Early Childhood Education (São José dos Pinhais, Pr). The parents/guardians answered a socioeconomic and demographic questionnaire, and the children were examined by a calibrated examiner (kappa=0.80). Cariogenic food consumption was measured using the Food Consumption Markers instrument (Ministry of Health, Brazil). The score of consumption of cariogenic foods was obtained by the sum of reports of consumption of foods with free sugar (SCF). Results: The prevalence of untreated dental caries was 21% (95%CI 17–24). In the multiple Poisson regression with robust variance, the higher prevalence of untreated dental caries was associated with the higher SCF (RPa=1.16; 95%CI 1.01–1.34; p=0.035), with the older age of the children (PRa=1.05; 95%CI 1.01–1.10; p=0.021), and inversely to the higher guardians’ education (PRa=0.62; 95%CI: 0.42–0.92; p=0.017). Conclusion: Cariogenic food consumption, measured through the Food Consumption Markers instrument, was associated with a higher prevalence of untreated dental caries in preschoolers.

Abstract The aim of this study was to evaluate the impact of oral conditions and health-related quality of life (HRQoL) on oral health-related quality of life (OHRQoL) in children and adolescents with blood coagulation disorders and hemoglobinopathies (BCDH). The study was cross-sectional and included 61 individuals aged 2 to 18 years with BCDH. Exams for dental caries (dmft/DMFT index), oral hygiene (simplified oral hygiene index – OHI-S), and gingival health (modified gingival index – MGI) were performed. The pediatric quality of life inventory™ (PedsQL™) generic core scale and oral health scale were used to measure HRQoL and OHRQoL. Spearman’s correlation coefficient (ρ) and the Mann-Whitney test (α = 0.05) were conducted to assess the relationship between covariates and the PedsQL™ oral health scale. The mean PedsQL™ oral health scale score was 76.66 (SD = 21.36). Worse OHRQoL was correlated with poor oral hygiene (ρ = -0.383; p: 0.004), poor gingival health (ρ = -0.327; p = 0.014), and better HRQoL (ρ = 0.488; p < 0.001). Greater untreated dental caries experience was associated with worse OHRQoL (p = 0.009). Worse oral health status in children and adolescents with BCDH negatively impacts OHRQoL, and OHRQoL and quality of life analyzed from a generic perspective are positively correlated constructs in this population. healthrelated related (HRQoL (OHRQoL .

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 Objective: To evaluate the characteristics and factors associated with the intake of ultra-processed cariogenic foods (UFC) by preschoolers during the COVID-19 pandemic. Material and Methods: This is a cross-sectional study involving parents of 672 children from two to five years old enrolled at public schools in Curitiba, Brazil. Parents answered a questionnaire about socioeconomic and demographic data, their behavior regarding the dietary education of their children (Parent Mealtime Action Scale - translated and validated for use in Brazil), and children's food intake (qualitative food frequency questionnaire - list of foods based on a report from the Pan American Health Organization). The data were analyzed using Poisson regression analysis (α=0.05). Results: About 43% of parents/guardians reported changes in their children's diet during the pandemic, being that diet got worse and better in 19% and 24% of the cases, respectively. The ultra-processed cariogenic foods with the highest daily intake frequencies were sweetened juices/sweetened drinks (0.52), followed by cookies (0.37), and candies (0.35). Parents with a lower level of education reported a daily frequency of UCF intake 1.36 times higher (PR=1.359; CI 95%: 1.106-1.669) in their children compared to those with a higher level of education. On the other hand, parents’/guardians’ report of higher intake and greater offer of fruits and vegetables to children was associated with low UCF intake (PR=0.716; CI 95%: 0.592-0.866). Conclusion: The lower level of formal education of parents/guardians and lower availability of fruits and vegetables were related to higher consumption of ultra-processed cariogenic foods by children.

Abstract: Parental behavior towards their children's oral health is strongly influenced by parent's Oral Health Literacy (OHL) level. This study evaluated the impact of parental OHL on preschool children's utilization of dental services. A cross-sectional study was conducted with parents of 419 children aged 3 to 5 years who answered a self-administered questionnaire about their perception of their children's oral health and whether their children had already been to a dental visit. Parental OHL level was assessed by the validated version of the Oral Health Literacy Adult Questionnaire (OHL-AQ) translated into Brazilian Portuguese. Univariate and multivariate Poisson regression analyses with robust variance were used for the data analysis (α = 0.05). Most children had already been to a dental visit (73%). Overall, 31.7% of the parents or guardians reported that their children had experienced dental pain or dental caries. Parental OHL level was classified by tercile as low, medium, and high. The final model showed independent associations between children who had already been to a dental visit and higher parental OHL level (PR = 1.16; 95%CI = 1.00-1.35) when compared to the lowest OHL level, higher parental educational level (PR = 1.39; 95%CI = 1.03–1.87) when compared to lower educational level, the report of children's pain and dental caries (PR = 1.22; 95%CI = 1.09–1.36) and married parents or parents in a common-law marriage (PR = 1.17; 95%CI = 1.03–1.93). The prevalence of children who had already been to a dental visit was higher among those parents with a higher OHL level when compared to those with a lower OHL level.

ABSTRACT Objective: To investigate whether children with premature birth (PB) and/or with low birth weight (LBW) have different tooth eruption patterns than those born at term or with normal weight. Material and Methods: Searches were performed in the PubMed, Cochrane Library, Sc1opus, Web of Science, LILACS, and BBO databases as well as the grey literature. Three independent reviewers were involved in study selection, data extraction, and bias assessment. The risk of bias was assessed using the Modified Newcastle-Ottawa Scale. Meta-analysis was conducted to compute the mean difference (MD) in mean chronological or adjusted age at the eruption of the first deciduous tooth between preterm children and those born at full term. The GRADE approach was used. Results: Among a total of 316 articles identified, 21 were eligible for inclusion and three were included in the meta-analysis. PB was associated with the delay in the first tooth deciduous eruption when chronological age was considered (MD: 1.36; 95%CI: 1.02–1.69) but not when considering adjusted age (MD: -0.30; 95%CI: -0.67–0.07). The evidence was graded as having very low quality. Conclusion: Based on a low certainty of evidence the PB is associated with the delayed eruption of the first deciduous tooth when considering chronological age but not when adjusted age is considered.

Abstract The aim of the present study was to analyze the association between parental eating behavior and untreated early childhood caries (ECC). A cross-sectional study was conducted with a representative sample of 432 parent-child dyads with children aged 18 to 36 months, at Municipal Child Education Centers in São José dos Pinhais, Brazil. The parents answered a questionnaire addressing demographic and socioeconomic characteristics, and the children were examined for dental caries (modified dmft index) by a single examiner (kappa = 0.80). A six-item questionnaire was administered addressing parental food consumption, parental control of the child’s food consumption, and parental offering of foods to the child. Three items were considered indicative of positive behavior, and three, of negative behavior. Univariate and multivariate Poisson regression analyses with robust variance were used for the data analysis (α = 0.05). The prevalence of untreated ECC was 20.3% (95%CI: 16.7–24.4). In the multiple regression model adjusted for the child’s age and the parent’s schooling, negative parental behavior was associated with a greater frequency of untreated ECC (PRa = 1.213; 95%CI:1.032–1.427, p = 0.019), but lost its significance when adjusted by positive parental behavior (PRa = 1.156; 95%CI: 0.983–1.358, p = 0.079). Based on the present findings, positive parental eating behaviors are capable of minimizing the impact of negative parental behaviors on the prevalence of untreated early childhood caries.

Abstract Social determinants of health (SDH) are strongly associated with oral health outcomes, and oral health literacy (OHL) is a potential factor that can modify this association. This study evaluated the association between SDH and OHL, including functional and interactive dimensions of OHL. The cross sectional study was conducted with 354 adults recruited from public dental clinics in southern Brazil. 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 interactional OHL. SDH was evaluated through a structured questionnaire, and economic class was determined based on the Brazilian Economic Classification Criteria. The statistical analysis involved bivariate and multivariate Poisson regression with robust variance (α=0.05) to estimate rate ratios (RR) and 95% confidence intervals (CI). Among the 354 participants, 284 (80.2%) were women and the mean age was 22.9 ± 4.9 years. The median BREALD-30 score was 24 (1st/3rd quintile: 20/27) and the median HeLD-14 score was 45 (1st/3rd quintile: 37/50). Most participants had up to eight years of schooling (71.5%) and belonged to the “C” Economic Class or lower (94.1%). The multiple regression analysis showed that schooling and economic class were associated with the BREALD-30 and HeLD-14 scores, income and age were associated with the HeLD-14 score, and marital status and occupation were associated with the BREALD-30 score. Different dimensions of OHL were associated with SDH in Brazilian adults. This aspect should be incorporated into strategies for improving OHL levels in individuals or populations.

Abstract Objective: To evaluate the impact of daily toothbrushing frequency on parental reports of dental pain and discomfort in preschoolers. Material and Methods: An observational cross-sectional study was conducted involving 376 children between four and five years of age at public preschools in the city of Campo Magro, Brazil. Parents/guardians answered a socioeconomic questionnaire that contained a single question on the child's daily toothbrushing frequency and the Brazilian version of the Dental Discomfort Questionnaire (DDQ-B). Statistical analysis involved bivariate and multivariate Poisson regression analyses (α=0.05). Results: After the adjustments in the multivariate analysis, the prevalence of dental pain and discomfort was lower among children whose last visit to the dentist was for prevention (PR = 4.42; 95% CI: 1.75– 11.14; p=0.002) and those with a higher daily toothbrushing frequency (PR = 2.13; 95% CI: 1.12–4.05; p=0.021). Conclusion: A lower toothbrushing frequency is associated with parental reports of dental pain and discomfort in preschoolers. Educational and preventive measures that stimulate an increase in daily toothbrushing frequency can contribute to a better oral health status in preschoolers, consequently, less prevalence of dental pain and discomfort.

Abstract Objective: To analyze if the oral health conditions in children and adolescents are associated with hemophilia (PROSPERO-42020168192). Material and Methods: The search strategy was performed in PubMed, Scopus, Lilacs/BBO, Web of Science, Cochrane, and Grey literature databases. Two independent researchers assessed the risk of bias in these studies by the Newcastle-Ottawa Scale. For the meta-analysis, the clinical conditions data were extracted as numerical variables according to their indexes, such as dental caries experience (dmft/DMFT), gingival condition (Modified Gingival Index - IGM), and oral hygiene (Plaque Index - PI). The quality of the evidence of the meta-analysis was evaluated by the GRADE tool (GRADEproGDT). Results: From a total of 431 studies, 27 were included, and 10 were included in the meta-analysis. The studies presented a moderate risk of bias, ranging from 2 to 7 points. The dental caries experience in primary (-0.62; CI95%: -1.68–0.43) and permanent dentitions (-0.05; CI95%: -0.69–0.59), gingival condition (-0.12; CI95%: -0.27–0.03), and oral hygiene (0.36; CI95%: -0.06–0.77) did not differ between the groups. Conclusion: Based on studies with very weak evidence, there were no differences in the oral health conditions of children and adolescents with and without hemophilia.

Objective: To analyze the association between food insecurity (FI) and sociodemographic factors in children. Methods: Study carried out from May to November 2017 with mothers of children (18 - 35 months) from the public school in São José dos Pinhais, Paraná, Brazil. FI was accessed through Brazilian Household Food Insecurity Measurement Scale. Multinomial logistic regression was used, with a hierarchical model. Results: 395 mothers/children participated. The prevalence of FI was 34.7 (95%CI 28.5;41.5) with 25.7% (95%CI 19.2;32.3) for mild FI (MiFI) and 9.0% (95%CI 8.5;9.4) for moderate/severe FI (MoSFI). Families in the lowest income tercile had a higher chance of MiFI (OR=3.06 – 95%CI 1.26;7.41) or MoSFI (OR=6.35 – 95%CI 1.89;21.4) when compared to the largest tercile. Higher prevalence of MiFI was identified in male children (OR=2.34 – 95%CI 1.49;3.68). Conclusion: AI was associated with lower income and MiFi with male children. Public policies to increase income must be included in AI reduction strategies.

Objetivo: Analisar a associação entre insegurança alimentar (IA) e fatores sociodemográficos em crianças. Métodos: Estudo realizado no período maio-novembro de 2017, com mães de crianças (18-35 meses) matriculadas na rede pública de ensino de São José dos Pinhais, Paraná, Brasil. A IA foi acessada pela Escala Brasileira de Insegurança Alimentar. Utilizou-se regressão logística multinomial com modelo hierárquico. Resultados: Participaram 395 mães/crianças. A prevalência da IA foi de 34,7% (IC95% 28,5;41,5), sendo 25,7% (IC95% 19,2;32,3) para IA leve (IAL) e 9,0% (IC95% 8,5;9,4) para IA moderada/grave (IAMG). Famílias pertencentes ao menor tercil de renda tiveram maior chance de IAL (OR=3,06 – IC95% 1,26;7,41) ou IAMG (OR=6,35 – IC95% 1,89;21,4), comparadas ao maior tercil. Maior prevalência de IAL foi identificada em meninos (OR=2,34 – IC95% 1,49;3,68). Conclusão: IA foi associada a menor renda; e IAL, ao sexo masculino da criança. Políticas públicas de aumento de renda devem ser incluídas nas estratégias de redução da IA.

ABSTRACT Objective: To investigate the possible relationship between early admission to the school of children in early childhood and oral health conditions (OH) and nutritional status (NS). Material and Methods: Cross-sectional study conducted with 140 children aged 3-4 years, selected for convenience, in 4 public schools in the city of São Paulo, Brazil, during 2016, divided into children with early (IE) and late (IL) admission at school. Comparisons between groups were performed for the presence of overweight / obesity (OW / OB), caries lesions (CL), malocclusion (MO) and dental biofilm (DB), in addition to socioeconomic and dietary data. Multiple regression analysis was applied to determine the association between age of admission at school and OH and NS. Results: Children with IE had CL = 28.1%; DB = 46.9%; MO = 54.7% and OW / OB = 25.9%. Children with IE had IL = 29.8%; DB = 35.1%; MO = 61.4% and OW / OB = 30.8%. No significant association was found between age of admission at school and CL: 1.40 (0.53-3.73) 0.490; DB: 0.51 (0.22-1.16) 0.112; MO: 1.77 (0.77-4.05) 0.173 and OW / OB: 1.27 (0.55-2.92) 0.568, [OR (95% CI) p]. Conclusion: The age of admission at school of children in early childhood did not show a significant association with OH and NS.

ABSTRACT Objective: To evaluate the systemic factors associated with Molar-Incisor Hypomineralization (MIH) etiology. Material and Methods: A total of 731 8-year-old schoolchildren enrolled in the public school system in Curitiba, Brazil, was randomly selected. The MIH diagnosis was performed by calibrated examiners (Kappa >0.80) according to the European Academy of Pediatric Dentistry criteria (2003). The systemic factors were collected through a semi-structured questionnaire and applied to the children’s mothers, addressing the medical history from pregnancy to the first three years of children’s life. Associations were analyzed by Poisson regression analysis with robust variance (p<0.05). Results: The systemic factors in the prenatal and perinatal periods were not associated with MIH (p>0.05). The children who used medications during the first years of life had a significantly higher prevalence of MIH (PRc = 2.18 CI = 95% 1.06-4.48; p=0.033). Conclusion: The use of medications during the first three years of children’s life is associated with a higher prevalence of MIH.
