Daily Toothbrushing Frequency and the Association with Parental Report of Dental Pain and Discomfort in Preschool Children

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.

No-shows at public secondary dental care for pediatric patients: a cross-sectional study in a large Brazilian city / Não comparecimento na atenção secundária pública em saúde bucal de pacientes pediátricos: estudo transversal em uma grande cidade brasileira

Abstract Missed appointments have a great economic, social and administrative impact on the management of public health services. This research aimed to study factors associated with non-attendance to the first appointments of pediatric patients in secondary dental care services in the city of Curitiba, Brazil. A cross-sectional study was performed using secondary data from the electronic health records of the Curitiba Municipal Secretary of Health. The study included all children (0-12 years) referred to secondary dental clinics in the years 2010 to 2013. Data were analyzed by the chi-square test and Pearson linear trend chi-square (α = 0.05). Binary logistic regression models were built. Data from 1,663 children were assessed and the prevalence of non-attendance was 28.3%. The variables associated with the non-attendance in inferential analysis (p < 0.05) and in the final model were the household income per capita (95% CI: 1.93-2.82) and the waiting time in virtual queue (95% CI: 1.000-1.002). Socioeconomic aspects and the waiting time in virtual queue, should be considered in the strategic planning of health services as they may influence the attendance of pediatric patients in secondary dental referral service.

Resumo O não comparecimento a consultas tem um grande impacto no gerenciamento dos serviços de saúde pública. O objetivo foi avaliar os fatores associados ao não comparecimento às primeiras consultas de pacientes pediátricos nos serviços de atenção secundária em saúde bucal na cidade de Curitiba, Brasil. Um estudo transversal foi desenvolvido com dados secundários obtidos de cadastros eletrônicos da Secretaria Municipal de Saúde de Curitiba. Participaram crianças de 0 a 12 anos de idade encaminhadas para atenção secundária nos anos de 2010 a 2013. Os dados foram analisados pelos testes de qui-quadrado de Pearson e qui-quadrado de tendência linear (α = 0,05). Foram constituídos modelos de regressão logística binária. Foram analisados os dados de 1.663 crianças. A prevalência de não comparecimento às primeiras consultas foi de 28,3%. As variáveis que estiveram associadas ao não comparecimento na análise inferencial (p < 0,05) e no modelo final foram a renda per capita familiar (95% CI: 1,93-2,82) e o tempo de espera em fila virtual (95% CI: 1,000-1,002). Aspectos econômicos e o tempo de espera em fila virtual devem ser considerados no planejamento estratégico dos serviços públicos de saúde bucal, pois podem influenciar o comparecimento de pacientes na atenção secundária.

Dental care utilization among children in Brazil: an exploratory study based on data from national household surveys / Utilização de serviços odontológicos entre crianças no Brasil: estudo exploratório a partir das pesquisas nacionais por amostra de domicílios

Abstract Wide availability of access to dental services can be considered a predictor of better oral health outcomes in a population. This article aims to compare data from the Brazilian National Household Sample Surveys (PNAD) on dental services utilization among children aged 4 to 12 years. This cross-sectional study was carried out using data from the 1998, 2003, and 2008 National Household Sample Surveys, involving a total of 61.438, 64.659 and 59.561 children, respectively. Ninety-nine percent confidence intervals were considered for the prevalence of each outcome of interest. In 1998, 60.8% (99%CI: 59.4;62.1) of children had been to a dentist; this prevalence was 65.5% (99%CI: 64.4;66.7) in 2003 and 73.8% (99%CI: 72.1;74.2) in 2008. In 1998, 41.2% (99%CI: 39.1;43.3) of children in the lowest household income quartile had been to a dentist; this value was 61.4% (99%CI: 59.5;63.2) in 2008. Among children from families whose head of household had 4 years of formal education or fewer, 49.5% and 63% had been to a dentist in 1998 and 2008, respectively. The lifetime prevalence of dentist attendance among Brazilian children increased between 1998 and 2008, especially among those from low-income families and those whose head of household had a low educational level.

Resumo A ampla disponibilidade de acesso aos serviços odontológicos pode ser considerada um fator preditor de melhores resultados na saúde bucal da população. O objetivo deste artigo é comparar os dados obtidos das Pesquisas Nacionais por Amostras de Domicílios (PNADs), em relação a utilização de serviços odontológicos, entre crianças de 4 a 12 anos. Estudo transversal, com dados obtidos a partir das PNADs realizadas em 1998, 2003 e 2008, envolvendo um total de 61.438, 64.659 e 59.561crianças, respectivamente. Considerou-se intervalos de confiança de 99% para os desfechos. No ano de 1998, 60,8% (IC99%: 59,4;62,1) das crianças haviam ido ao dentista, em 2003, 65,5% (IC99%: 64,4;66,7), e em 2008, 73,8% (IC99%: 72,1;74,2). Com relação à renda domiciliar, em 1998, 41,2% (IC99%: 39,1;43,3) das crianças inseridas nas famílias na menor faixa de renda foram ao cirurgião-dentista, em 2003 49,9% (IC99%: 48;51,9) o fizeram e, em 2008, 61,4% (IC99%: 59,5;63,2). Entre as que pertenciam a famílias onde o chefe possuía até 4 anos de estudo, 49,5% e 63%, em 1998 e 2008, foram às consultas odontológicas. A prevalência de crianças brasileiras que já haviam ido ao dentista aumentou entre 1998 e 2008, especialmente entre aquelas pertencentes a famílias com renda domiciliar menor e com chefes possuindo menor escolaridade.

Demarcated opacity in primary teeth increases the prevalence of molar incisor hypomineralization

Abstract This cross-sectional study aimed to assess the prevalence of molar incisor hypomineralization (MIH) and its relationship with the number of primary teeth with developmental defects of enamel (DDE). A representative population-based sample of 731 schoolchildren was randomly selected from the public school system in Curitiba, Brazil. Schoolchildren aged 8 years with fully erupted permanent first molars and incisors were eligible for the study. MIH and DDE were classified by four calibrated examiners (kappa > 0.75) according to EAPD criteria and to the FDI-modified DDE index. Clinical data were collected in a school environment. Socioeconomic information was collected through a self-administered semistructured questionnaire applied to the children's caregivers. Statistical analyses were carried out using Poisson multiple regression with robust variance (α = 0.05). MIH prevalence was 12.1% (95%CI: 10-15), and opacities were the most prevalent defect. Socioeconomic factors were not associated with MIH. Children with demarcated opacity in primary teeth presented a higher prevalence of MIH than those without DDE in primary teeth. In the multiple analysis, the increase of one primary tooth affected by demarcated opacity increased the prevalence of MIH by 33% (PR = 1.33, 95%CI: 1.15-1.53, p < 0.001). Asian children had a higher prevalence of MIH (PR = 2.91, 95%CI: 1.08-8.09 p = 0.035) than did Caucasian children.Conclusion: Based on these findings, the prevalence of MIH in Curitiba was 12.1%. Demarcated opacity in primary teeth could be considered a predictor of MIH.
