Resumo O objetivo deste estudo foi avaliar a associação entre cárie dentária não tratada (CDNT) e insegurança alimentar (IA) em escolares de diferentes estratos de renda. Foi realizado um estudo de base populacional com uma amostra de 584 escolares de 12 anos de idade. Exames clínicos bucais foram realizados e IA foi determinada por meio de uma escala validada. Outras variáveis foram analisadas por serem de interesse para a estratificação dos resultados (renda domiciliar per capita) ou como variáveis de confusão. A prevalência de CDNT e IA foi de 45% e 39%, respectivamente. Os modelos multivariados demonstraram que a CDNT foi significativamente mais prevalente entre as crianças com IA alimentar e renda per capita de até US$ 70,71 do que entre aqueles no mesmo estrato de renda que estavam livres de IA [RP = 1,52 (IC 95% = 1,01 -2,29)]. A IA foi associada com uma maior frequência de CDNT em escolares de baixa renda, porém não teve impacto significativo sobre esta variável entre crianças de diferentes estratos de renda. Diante disso, garantir o acesso a uma alimentação de qualidade pode representar uma boa estratégia para minimizar as iniquidades em saúde bucal e reduzir a experiência de cárie dentária em escolares de baixa renda.

Abstract The aim of the present study was to assess the association between untreated dental caries (UDC) and household food insecurity (HFI) among schoolchildren in different income strata. A population-based study was carried out with a sample of 584 12-y-old schoolchildren. Oral examinations were performed and HFI was determined using a validated scale. Other independent variables were analyzed for being of interest to the stratification of the results (per capita household income) or for acting as potential confounding variables. The prevalence of UDC and HFI was 45% and 39%, respectively. The multivariate models demonstrated that the UDC was significantly more prevalent among children in food-insecure households with per capita income of up to US$ 70.71 than among those in the same income stratum that were free of HFI [PR = 1.52 (95%CI = 1.01-2.29)]. HFI was associated with a greater frequency of UDC among low-income schoolchildren, but had no significant impact on this variable among children from other income strata. Thus, ensuring access to quality food may be a good strategy for minimizing inequities in oral health and reducing dental caries experience among schoolchildren from low-income families.

ABSTRACT Objective To evaluate the influence of disease control, expressed by the mean values of glycated hemoglobin (HbA1c), in the oral health of children and adolescents with diabetes mellitus type 1 (T1DM). Subjects and methods A cross sectional study involving 87 children and adolescents (59 girls), 10 ± 2.6 years old. The participants were divided into three groups: HbA1c ≤ 8%, 8% < HbA1c ≤ 10% and HbA1c > 10%. The duration of the disease, age and average HbA1c were obtained from their medical records. Oral health was evaluated according to the following indexes: Simplified Oral Hygiene Index (OHI-S); Community Periodontal Index (CPI); Decayed, Missing or Filled Teeth Index (DMFT/dmft) for permanent and deciduous teeth; and the stimulated salivary flow rate (SSFR). Results The median SSFR was 1.1 mL/min in the group with HbA1c ≤ 8%, 0.7 mL/min in the intermediary group and 0.6 mL/min in the HbA1c > 10% group. A significant decrease in salivary flow was observed with an increase in HbA1c (p = 0.007). The DMFT/dmft and CPI indexes were higher in individuals with higher HbA1c values. More caries-free individuals were found in the group with HbA1c ≤ 8% compared to those with HbA1c > 10%. The group with HbA1c > 10% exhibited more caries and bleeding gums than the other groups. HbA1c values in girls were higher than in boys. Conclusion Children and adolescents with unsatisfactory glycemic control, represented by higher HbA1c concentrations, exhibited a higher frequency of caries and gingivitis, and a reduction in salivary flow.

The aim of the present study was to analyze dental research trends in Brazil over the past nine years. All abstracts presented at the 26th Annual Meeting of the Brazilian Society for Dental Research in 2009 (n = 2648) were classified based on field of knowledge, home institution and geographic region. Data were compared with those previously published based on abstracts presented at various meetings. Between 2001 and 2006, five fields of knowledge had a greater than 10% representation among the total number of studies. These fields included restorative dentistry/dental materials (RD/DM), periodontics, endodontics, pediatric dentistry and population-based oral health. In 2009, only RD/DM maintained a greater than 10% proportion of meeting abstracts, and basic fields comprised the second position among those fields with greater representation (9.8%). The majority of research studies were performed at public institutions, and the number of abstracts per state increased significantly in 2009 (Wilcoxon test, p < 0.001). The southeastern region of Brazil submitted the greatest number of abstracts; however, other regions also demonstrated increased participation in research (11%). The percentage distribution of abstracts between states remained constant (Wilcoxon test, p = 0.255; r s = 0.873). The results of the present study suggest a slight shift in the scientific research profile in Brazilian dentistry: fields related to professional disciplines have declined in relative research participation, while increasing interest has been observed in basic fields and new specialties.
