Chronic oral diseases are rarely studied together, especially with an emphasis on their common risk factors. This study examined the association of added sugar consumption on "chronic oral disease burden" among adolescents, with consideration of obesity and systemic inflammation pathways through structural equation modeling. A cross-sectional study was conducted of a complex random sample of adolescent students enrolled at public schools in São Luís, Brazil ( n = 405). The outcome was chronic oral disease burden, a latent variable based on the presence of probing depth ≥4 mm, bleeding on probing, caries, and clinical consequences of untreated caries. The following hypotheses were tested: 1) caries and periodontal diseases among adolescents are correlated with each other; 2) added sugar consumption and obesity are associated with chronic oral disease burden; and 3) chronic oral disease burden is linked to systemic inflammation. Models were adjusted for socioeconomic status, added sugar consumption, oral hygiene behaviors, obesity, and serum levels of interleukin 6 (IL-6). All estimators of the latent variable chronic oral disease burden involved factor loadings ≥0.5 and P values <0.001, indicating good fit. Added sugar consumption (standardized coefficient [SC] = 0.212, P = 0.005), high IL-6 levels (SC = 0.130, P = 0.036), and low socioeconomic status (SC = -0.279, P = 0.001) were associated with increased chronic oral disease burden values. Obesity was associated with high IL-6 levels (SC = 0.232, P = 0.001). Visible plaque index was correlated with chronic oral disease burden (SC = 0.381, P < 0.001). Our finding that caries and periodontal diseases are associated with each other and with added sugar consumption, obesity, and systemic inflammation reinforces the guidance of the World Health Organization that any approach intended to prevent noncommunicable diseases should be directed toward common risk factors.

Background Periodontal disease is associated with metabolic syndrome, and during pregnancy, it is linked to preeclampsia and preterm birth. We hypothesized that soft drink consumption, which has also been associated with metabolic disorders, may also be linked to periodontal disease. The purpose of this study was to evaluate the association between soft drink consumption and periodontal status in pregnancy. Methods This was a cross‐sectional study nested in BRISA (Brazilian Ribeirão Preto and São Luís Birth Cohort Studies). Pregnant women (n = 1,185) completed a questionnaire and underwent periodontal examination from the 22nd to 25th week of pregnancy. The explanatory variable was the frequency of soft drink consumption (times per week). The outcome was periodontal status measured as the number of teeth with probing depth ≥4 mm with bleeding on probing (PD/BOP) or with clinical attachment level ≥4 mm (CAL). Means ratio (MR) was estimated using zero‐inflated Poisson, adjusted for maternal age and income. Results The higher tertile of consumption of soft drinks during pregnancy was associated with PD/BOP (MR = 1.34; 95% confidence interval (CI): 1.03 to 1.75); while the highest tertile of diastolic blood pressure was also associated to CAL (MR = 1.21; 95% CI 1:07 to 1.35). Conclusion High soft drink consumption was associated with the number of teeth with PD/BOP in pregnant women, suggesting that beverage consumption is a factor that contributes to the systemic inflammatory burden, which is common to periodontal disease, metabolic syndrome, and adverse pregnancy outcomes.

Objective:This study aims to evaluate the association between early childhood caries (ECC) and maternal caries status, and the maternal perception of ECC risk factors.Materials and Methods:A cross-sectional study was carried out with 77 mother-child pairs, the children ranging from 12 to 36 months of age and their mothers, who were seeking dental care at a health center in São Luís, Maranhão, Brazil. Data collection was conducted using a specific questionnaire for mothers. Oral clinical examination of the mother-child binomial to assess caries incidence, gingival bleeding (GB) and visible plaque was done. Home visits were performed in 10% of the sample in order to observe the environmental conditions, dietary habits and dental hygiene practices.Results:The findings showed that the caries prevalence in children was 22.5 times higher in the mother who had decayed tooth (prevalence ratio [PR] = 22.5, confidence interval [CI] 95% = 3.2–156.6, P < 0.001). GB also was observed in 14 mothers and children, the PR in pair was 12.2 (CI95% = 1.6–88.9, P < 0.001). The variables are related for the mother-child binomial in regression linear analysis.Conclusion:The maternal caries status was associated with ECC.
