Early Respiratory Infections and Dental Caries in the First 27 Years of Life: A Population-Based Cohort Study

Chronic periodontitis (CP) may increase the risk of exacerbation of and hospitalization for respiratory infections. The aim of the present study was to determine whether CP is associated with acute respiratory infections by analyzing a population-based longitudinal database from the National Health Insurance Service—National Sample Cohort. Univariate and multivariate logistic regression analyses were conducted to assess the association between CP and acute respiratory infections, including acute nasopharyngitis, acute pharyngitis, acute tonsillitis, acute laryngitis and tracheitis, acute bronchitis, and acute bronchiolitis, while adjusting for the confounding effects of sociodemographic variables (sex, age, household income, and smoking status) and comorbidities (diabetes mellitus). Among 545,416 recruited participants, 98,490 (18.1%) had CP. Multivariate analysis, adjusted for sociodemographic variables and comorbidities, showed that except influenza and pneumonia, total acute respiratory infections (odds ratio (OR), 1.33; 95% confidence interval (CI), 1.28–1.38; p < 0.001), acute upper respiratory infections (OR, 1.26; 95% CI, 1.22–1.29; p < 0.001), and acute lower respiratory infections (OR, 1.23; 95% CI, 1.20–1.26; p < 0.001) were significantly associated with CP. The findings of the current cohort study suggest an association between CP and acute respiratory infections. Particularly, CP seems to increase the risk of acute upper and lower respiratory infections.

Children’S Oral Health

Abstract Background To understand determinants of oral health inequalities, multilevel modelling is a useful manner to study contextual factors in relation to individual oral health. Several studies outside Europe have been performed so far, however, contextual variables used are diverse and results conflicting. Therefore, this study investigated whether neighbourhood level differences in oral health exist, and whether any of the neighbourhood characteristics used were associated with oral health. Methods This study is embedded in The Generation R Study, a prospective cohort study conducted in The Netherlands. In total, 5 960 6-year-old children, representing 158 neighbourhoods in the area of Rotterdam, were included. Data on individual and neighbourhood characteristics were derived from questionnaires, and via open data resources. Caries was assessed via intraoral photographs, and defined as decayed, missing and filled teeth (dmft). Results Differences between neighbourhoods explained 13.3% of the risk of getting severe caries, and 2% of the chance of visiting the dentist yearly. After adjustments for neighbourhood and individual characteristics, neighbourhood deprivation was significantly associated with severe dental caries (OR: 1.48, 95% CI: 1.02–2.15), and suggestive of a low odds of visiting the dentist yearly (OR: 0.81, 95% CI: 0.56–1.18). Conclusions Childhood caries and use of dental services differs between neighbourhoods and living in a deprived neighbourhood is associated with increased dental caries and decreased yearly use of dental services. This highlights the importance of neighbourhoods for understanding differences in children’s oral health, and for targeted policies and interventions to improve the oral health of children living in deprived neighbourhoods.

Chronic Childhood

Dental caries is the most common chronic childhood disease. Recent studies have suggested that dental caries harbor respiratory infections in adults. We investigated the association between dental caries and influenza in children. In this study, 42,812 children aged 2.5 years, 38,540 children aged 5.5 years, and 34,124 children aged 10 years were included in the analysis from the Longitudinal Survey of Newborns in the 21st Century in Japan, which targeted all children born during a certain period in 2001. We used information on dental caries treated at hospitals and clinics in the past year as exposure and influenza as outcome during the observation periods (1.5–2.5, 4.5–5.5, and 9–10 years of age). We performed a log-binomial regression analysis, adjusting for potential confounders, and stratified analysis according to previous dental caries status. The presence of dental caries increased the incidence of influenza in all three target ages compared with the absence of dental caries. The incidence of influenza increased with the presence of current dental caries, regardless of the presence of past dental caries. These associations were observed irrespective of household income. Early detection and treatment of dental caries may reduce the risk of influenza in children.
