Data from 765 2- to 4-year-old children attending a statutory National Day of Children's Vaccination in Macapá (Northern Brazil) were analysed. Caries and severe caries were indicated by the dmfs and pufa indices, respectively. Parents completed a questionnaire including questions on socioeconomic factors and the impact of oral conditions on their children's quality of life using the Brazilian version of the Parental Perceptions Questionnaire for preschool children. Logistic regression was used to test the unadjusted and adjusted associations of caries and severe caries with different aspects of children's quality of life. Sixty-two and five per cent of children had dental caries (dmfs index > 0) and severe caries (pufa index > 0), respectively. In the adjusted models, having caries was significantly related to toothache and problems eating certain foods as well as to be absent from school and ashamed to smile, whereas having severe caries was significantly related to toothache and problems eating certain foods only. Neither caries nor severe caries was related to stop playing with other children. This study shows that caries and severe caries may have a considerable impact on some aspects of preschool children's quality of life.

  This systematic review sought to quantitatively answer the question as to whether, in tooth cavities of the same size, type of dentition and follow-up period, resin-modified glass-ionomer (GIC)This systematic review sought to quantitatively answer the question as to whether, in tooth cavities of the same size, type of dentition and follow-up period, resin-modified glass-ionomer (GIC) restorations, when compared to conventional GIC restorations, offer a significant caries preventive effect, as measured by the absence of caries lesions at the margin of restorations. Six databases were searched for articles in English, Portuguese or Spanish until 07 May 2009. Four articles were accepted and 22 separate datasets extracted. The difference between both types of material were computed as relative risk (RR) with 95% confidence interval (CI). No meta-analysis was undertaken due to aspects of clinical/methodological heterogeneity. The results of the extracted datasets ranged between RR 0.90 (95% CI 0.81-1.01) and 1.08 (95% CI 0.71-1.63; p > 0.05) indicating no difference in the caries preventive effect between both types of materials. Further high-quality randomized control trials are needed in order to confirm these results.

  The main objective of this study was to assess whether dental caries status was related to nutritional status in preschool urban Brazilian children aged 12-59 months. Dental and anthropometricThe main objective of this study was to assess whether dental caries status was related to nutritional status in preschool urban Brazilian children aged 12-59 months. Dental and anthropometric examinations were conducted on 1,018 12-59-month-old children during the National Day of Children Vaccination. Dental caries prevalence and severity were measured using the decayed, missing or filled surfaces (dmfs) index. The World Health Organization (WHO) Child Growth Standards Reference was used to evaluate nutritional status. Results on nutritional status were presented as Z-scores. The data collected included socio-economic conditions. Multilevel linear regression was applied to investigate the effect of nutritional, socio-economic, and demographic factors on the status of children's dental caries. Caries was present in 23.4% of children. The final hierarchical logistic model showed a significant association between nutritional status and caries experience. Children with low Z-scores in some indexes had an increased risk of having caries. In addition, children whose mothers had < 8 yr of education and were from lower-income families had an increased risk of high levels of dental caries. There was an association between nutritional and socio-economic factors, and dental caries. In conclusion, underweight children and those with adverse socio-economic conditions were more likely to have caries experience.
