Abstract
OBJECTIVE To estimate the effect of income at birth on adulthood tooth loss due to dental caries in 539 adults from the 1982 Pelotas birth cohort. METHODS Family income was collected at birth. Tooth loss was clinically assessed when individuals were aged 31. Dental visit and oral hygiene at age 25 were considered mediators. Confounders included maternal skin color, and individual's skin color, sex, and income in adulthood. Marginal structural modeling was used to estimate the controlled direct effect of income at birth on tooth loss due to dental caries that was neither mediated by the use of dental service nor oral hygiene. RESULTS Forty-three percent of the individuals of low income at birth lost one/two teeth, and 23% lost three or more; among those non-poor, the prevalence was 30% and 14%, respectively. Poor individuals at birth had a 70% higher risk for missing teeth in adulthood than those non-poor. The risk of losing one/two (risk ratio 1.68) and three or more teeth (risk ratio 3.84) was also higher among those of low income at birth. CONCLUSIONS Economic disadvantage at birth had an effect on tooth loss due to dental caries at age 31 not mediated by individual risk factors.

Abstract
AIM This cross-sectional study aimed to assess the relationship between weight status and gingival inflammation in Brazilian schoolchildren aged 8- to 12-year old, when controlling for potential confounders. METHODS Overall, 1211 children aged 8- to 12-year old from public and private schools in Southern Brazil were selected by a two-stage cluster method. Questionnaires were used to assess socio-demographic data and oral hygiene habits. Oral examination evaluated presence of plaque and gingival bleeding. Anthropometric measures were collected to obtain body mass index. Multivariate Poisson regression was used for data analysis (Prevalence Ratio/95% Confidence Interval). RESULTS Prevalence of gingivitis was 44.0%. Mean and median values of gingival bleeding sites were 3.10 and 2.0 respectively. Obese/overweight children totalized 34.6%. In multivariate adjusted analysis, sex (PR 0.86; 95%CI 0.75;0.98), maternal schooling (PR 1.09; 95% CI 1.01;1.18), plaque (PR 1.37; 95% CI 1.26;1.50), dental caries experience (PR 1.16; 95% CI 1.01;1.36) and bleeding during tooth brushing (PR 1.27; 95% CI 1.11;1.48) were associated with the outcome. In the sex-stratified analysis, overweight/obese boys presented a greater risk for gingivitis (PR 1.22 95% CI 1.01;1.48). CONCLUSIONS Gingivitis was not associated with obesity/overweight in the total sample. Gender differences seem to influence the relationship between gingivitis and obesity/overweight; a stronger association was noted among boys than girls.
