    OBJETIVO : Analisar a associação entre ser beneficiário do Programa Bolsa Família e condições de saúde bucal entre escolares. MÉTODOS : Estudo transversal com 1.107 escolares entre oito e 12 anos de idade, provenientes de 20 escolas públicas e particulares da cidade de Pelotas, RS, em 2010. Os beneficiários do Programa Bolsa Família foram verificados por meio de lista fornecida pelas escolas participantes do estudo. Informações demográficas, socioeconômicas, de uso de serviço odontológico e de higiene bucal foram obtidas por meio de questionários respondidos pelos escolares e por seus pais. O exame clínico avaliou a presença de placa dental e experiência de cárie. Os dados foram analisados por meio dos testes do Qui-quadrado e Qui-quadrado de tendência linear e por regressão de Poisson (razão de prevalência; intervalo de confiança de 95%). RESULTADOS : Crianças de família não nuclear, que apresentavam CPOD ≥ 1 e que nunca haviam feito uso de serviço odontológico na vida estiveram associadas ao recebimento do Programa Bolsa Família. O modelo final mostrou que a prevalência de cárie foi duas vezes maior (RP 2,00; IC95% 1,47;2,69) em alunos beneficiários do Programa que também apresentaram maior severidade da doença, quando comparados aos alunos de escolas particulares (RM 1,53; IC95% 1,18;2,00). A prevalência de escolares que nunca haviam ido ao dentista foi mais de seis vezes maior em beneficiários do Programa Bolsa Família (RP 6,18; IC95% 3,07;12,45), em comparação com aqueles das escolas privadas, após ajustes. CONCLUSÕES : Escolares beneficiários do Programa Bolsa Família possuem maior carga de cárie e são os que menos acessam os serviços odontológicos. Esses achados sugerem a necessidade de incorporação da saúde bucal nas condicionalidades do Programa Bolsa Família

    The objective of this study was to assess the prevalence and characteristics of oral lesions and oral self-examination and the association between these variables and life course determinants in a young population. A representative sample (n = 720) of all births occurring in Pelotas, Rio Grande do Sul State, Brazil, in 1982, was investigated and the outcomes were assessed in 2006. Data regarding exploratory variables was collected from other cohort waves. The prevalence of oral lesions was 23.3% (95%CI: 20.3-26.6). A total of 31% of individuals (95%CI: 27.6-34.4) reported never having performed oral self-examination. Multivariable analysis showed that low socio-economic status at birth, lack of oral hygiene instruction from a dentist up to the age of 15 years and smoking habits at the age of 22 year were associated with the presence of oral lesions. Performing oral self-examination was associated with high levels of maternal schooling at birth and having received oral hygiene orientation from a dentist up to the age of 15 years. Socioeconomic and behavioral factors are associated with both presence of oral mucosal lesions and the habit of performing self-examination

METHODS : A cross-sectional study was conducted with 1,107 schoolchildren aged between eight and 12 years from 20 public and private schools in Pelotas, RS, Southern Brazil. A list of all children receiving the Bolsa Família program was provided by the participant schools. Demographic, socioeconomic and oral hygiene information were assessed using a questionnaire completed by the schoolchildren and their parents. Dental exams were performed to assess the presence of dental plaque and prevalence of dental caries. Data were analyzed by Chi-square test, Chi-square test for linear trend and multivariate Poisson Regression (prevalence ratio; 95% confidence interval). RESULTS : Schoolchildren from non-nuclear families, with a DMFT ≥ 1 and who had never visited a dentist were associated with receiving the Bolsa Família. Final model showed that caries prevalence was twice as high (PR 2.00; 95%CI 1.47;2.69) in schoolchildren benefiting from the Bolsa Família . It was also showed that schoolchildren benefiting from the program presented greater severity of dental caries compared to school children from private schools (RR 1.53; 95%CI 1.18;2.00). After final adjustments, the prevalence of schoolchildren who have never visited a dentist was six times higher in children who received the government benefit (PR 6.18; 95%CI 3.07;12.45) compared to those from private schools. CONCLUSIONS : Schoolchildren benefiting from the Bolsa Família program experienced more caries lesions and have less frequently accessed dental care services, which suggest the need to include oral health in the program.OBJETIVO : Analizar la asociación entre ser beneficiario del Programa Beca Familia y condiciones de salud bucal entre escolares.

    The aim of this study was to evaluate the influence of the poly-L-lactic acid (PLLA)- based scaffold’s pore size on the proliferation and differentiation of dental pulp stem cells (DPSCs). The scaffolds were prepared in pulp chambers of 1-mm-thick tooth slices from third molars using salt crystals (150-250 μm or 251-450 μm) as porogen. DPSC (1x105 cells) were seeded in the scaffolds with different pore sizes, and cultured in 24-well plates. The cell proliferation was evaluated using the WST-1 assay after 3-21 days. Furthermore, RT-PCR was used to assess the differentiation of the DPSCs into odontoblasts, using markers of odontoblastic differentiation (DSPP, DSP-1 and MEPE). RNA from human odontoblasts was used as control. Cell proliferation rate was similar in both scaffolds except at the 14th day period, in which the cells seeded in the scaffolds with larger pores showed higher proliferation (p<0.05). After 21 days DPSCs seeded in both evaluated scaffolds were able of expressing odontoblastic markers DMP-1, DSPP and MEPE. In summary, both scaffolds tested in this study allowed the proliferation and differentiation of DPSCs into odontoblast-like cells.O objetivo desse estudo foi avaliar a influência do tamanho dos poros de um scaffold à base de poli ácido láctico (PLLA) sobre a proliferação e diferenciação de células tronco da polpa dental (dental pulp stem cells - DPSC). Os scaffolds foram preparados dentro da câmara pulpar de discos de terceiros molares (1 mm), utilizando sal como porógeno (150-250 μm ou 251-450 μm). DPSC (1x105 células) foram semeadas nos scaffolds com diferentes tamanhos de poros e cultivadas em placas de 24 poços. A proliferação celular foi avaliada utilizando WST-1 após 3-21 dias. Além disso, RT-PCR foi utilizado para avaliar a diferenciação odontoblástica das DPSC utilizando marcadores da diferenciação odontoblástica (DSPP, DMP-1 e MEPE). RNA obtido de odontoblastos humanos foi utilizado como controle. A taxa de proliferação celular foi semelhante nos dois scaffolds avaliados, exceto no 14° dia, no qual as células cultivadas nos scaffolds com os maiores poros apresentaram uma maior taxa de proliferação (p<0,05). Após 21 dias, as DSPC cultivadas em ambos scaffolds avaliados foram capazes de expressar os marcadores odontoblásticos DMP-1, DSPP e MEPE. Em resumo, ambos scaffolds avaliados nesse estudo permitiram a proliferação e diferenciação odontoblástica das DPSC

    Purpose: The practice of dentistry usually involves contact with secretions from the oral cavity through percutaneous injuries, which is a risk factor for the transmission of infections, especially hepatitis B, between the professional and patients. This study aimed to assess the prevalence of percutaneous injuries and associated factors among dental surgeons. Methods: A total of 187 dental surgeons from the city of Pelotas, Brazil, participated in this study. Data concerning the socio-demographic aspects, occurrence of accidents, types of instruments, use of personal protective equipment, immunization coverage related to hepatitis B and tests for serum conversion were collected through self-reported questionnaires. The data underwent descriptive analysis and chi-square testing or Fisher’s exact test, with P<0.05. Results: The prevalence of percutaneous injuries was 59.8%, and there was no association with the risk factors evaluated. Of the dentists interviewed, 97.3% had been vaccinated against hepatitis B; however, only 86.2% had received the three recommended doses. The use of probes and handling needles were the most common causes of percutaneous injuries (37.0% and 29.0%, respectively). Conclusion: The results showed that the prevalence of percutaneous injuries was high among dental surgeons, and there is a need for emphasis on the prevention of hepatitis B through the administration of the three vaccine doses and the use of personal protective equipment

    This study compared quantitatively and qualitatively the DNA extracted from buccal cells collected from the upper or lower gutter areas.Buccal cells were collected from the upper (n=15) and lower gutter (n=15) region from 15 volunteers using a special cytobrush (Gentra),totaling 2 collections from each individual. DNA was extracted from the samples according to the manufacturer’s instructions. The DNA obtained was qualitatively and quantitatively evaluated by 2 calibrated blind examiners using spectrophotometry and analysis of DNA bands(0.8% agarose gel electrophoresis). Data was statistically analyzed by one-way ANOVA (α=0.05). Means and standard derivation (SD) for total DNA yield from the upper and lower gutter area were 12.2 μg (12.0) and 9.4 μg (8.5), respectively (p=0.821). There was higher(p<0.05) DNA purity for the upper gutter (1.79; 0.05) when compared to lower gutter area (1.66; 0.10). Regarding to the DNA quality,no differences were observed between the 2 location sites, but all samples showed similar degree of degradation. In conclusion, it wouldbe recommendable that buccal cells for DNA extraction be collected from the upper gutter area in the attempt to increase DNA purity
