ABSTRACT The aim of this study was to describe the methodology and results of oral health studies nested in a birth cohort in Pelotas, Southern Brazil. For the oral health studies a sub-sample (n = 900) was selected from the cohort and dental examinations and interviews were performed at ages 15 (n = 888) and 24 years (n = 720; 81.1%). Data collection included dental outcomes, dental care, oral health behaviors, and use of dental services. Mean DMF-T varied from 5.1 (SD = 3.8) to 5.6 (SD = 4.1) in the study period. The proportion of individuals with at least one filled tooth increased from 51.9% to more than 70%. Individuals who had always been poor used dental services less and had fewer healthy teeth on average than those who had never been poor. Individuals with decreasing or increasing family income trajectories showed intermediate values. An increase was seen in the number of healthy teeth from age 15 to 24 only among those who had never been poor. A history of at least one experience with poverty had a negative impact on oral health in adulthood.

    ABSTRACT: To evaluate the association between obesity and periodontal disease and the mediating effect of oral hygiene, systemic inflammation and carbohydrate intake. Subjects born in 1982 in Pelotas, Brazil (n = 5,914), have been followed for several times. Oral health was assessed in a representative sample of 720 individuals at 24 years. Obesity, waist circumference and number of episodes with obesity between 15 and 23 years of age were the main exposures. Mediating effect of oral hygiene, C-reactive protein level and carbohydrate consumption was also assessed. Obese individuals were more likely to have ≥ 2 teeth with gingival bleeding. However, after adjusting for confounders, the association was not statistically significant [OR (obese × 2 or more teeth) 1.72 (95% CI: 0.95, 3.11)] and adjustment for potential mediators decreased the OR (OR = 1.38). The risk of presenting calculus in obese subjects was 10% higher [PR 1.10 (95% CI: 1.02, 1.18)]. The number of episodes of obesity between 15 and 23 years was associated with dental calculus. Periodontal pockets were not associated with obesity. Systemic inflammation and oral hygiene may be mediating the association between obesity and gingivitis. Obesity was not associated with periodontal pockets in young adults in this cohort.

    ABSTRACT: To investigate the association of direct posterior restorations with gingival bleeding and dental calculus in young adults from a birth cohort. A representative sample (n = 720) of 5,914 infants born live in Pelotas, Brazil, in 1982, were prospectively investigated, and posterior restorations and periodontal health outcomes assessed when they were 24 years of age. Tooth-level exploratory variables included the presence and number of restoration's surfaces. Demographic and socio-economic characteristics, oral health instructions, dental floss usage, dental caries presence and smoking were also considered whilst gingival bleeding and dental calculus were the outcomes. Multilevel logistic regression was carried out. Class I cavities were found in 15.2% (95%CI 14.5 - 15.9) of the teeth and class II in 3.6% (3.3 - 4.0). Percentage of teeth with gingival bleeding was 6.1% (5.6 - 6.6) and that with dental calculus 22% (21.2 - 22.8). Even after all the individual variables were controlled for, the presence of a class I [OR1.51 (1.14-2.00)] and class II [OR 1.76 (1.04-2.97)] cavities was positively associated with gingival bleeding. Class I [OR1.36 (1.13-1.65)] and Class II [OR1.80 (1.28-2.53)] cavities were associated with dental calculus also. Posterior restoration and higher number of restored surfaces was associated with a higher prevalence of gingival bleeding and dental calculus around the restoration.

    ABSTRACT: Objectives. We sought to determine the extent to which early life conditions and adverse life events impact chewing ability in middle and later adulthood. Methods. Secondary analyses were conducted based on data from waves 2 and 3 of the Survey of Health, Ageing, and Retirement in Europe (SHARE), collected in the years 2006 to 2009 and encompassing information on current chewing ability and the life history of persons aged 50 years or older from 13 European countries. Logistic regression models were estimated with sequential inclusion of explanatory variables representing living conditions in childhood and adverse life events. Results. After controlling for current determinants of chewing ability at age 50 years or older, certain childhood and later life course socioeconomic, behavioral, and cognitive factors became evident as correlates of chewing ability at age 50 years or older. Specifically, childhood financial hardship was identified as an early life predictor of chewing ability at age 50 years or older (odds ratio = 1.58; 95% confidence interval = 1.22, 2.06). Conclusions. Findings suggest a potential enduring impact of early life conditions and adverse life events on oral health in middle and later adulthood and are relevant for public health decision-makers who design strategies for optimal oral health.
