Reduced access to dental care may increase cardiovascular risk; however, socioeconomic factors are believed to confound the associations. We hypothesized that the relation persists despite economic wellness and high education, with reduced access to dental care affecting cardiovascular risk at least in part through its effect on blood pressure (BP), possibly mediated by systemic inflammation. We first assessed the sociodemographic and clinical characteristics related to last dental visit timing (≤ or >6 months; self‐reported) using national representative cross‐sectional data. Then, the association of last dental visit timing with clinic BP was selectively investigated in highly educated, high income participants, further matched for residual demographic and clinical confounders using propensity score matching (PSM). The mediating effect of systemic inflammation was formally tested. Machine learning was implemented to investigate the added value of dental visits in predicting high BP over the variables included in the Framingham Hypertension Risk Score among individuals without an established diagnosis of hypertension. Of 27,725 participants included in the population analysis, 46% attended a dental visit ≤6 months. In the PSM cohort (n= 2350), last dental visit attendance >6 months was consistently associated with 2 mmHg higher systolic BP (P= 0.001) and with 23 to 35% higher odds of high/uncontrolled BP compared with attendance ≤6 months. Inflammation mildly mediated the association. Access to dental care improved the prediction of high BP by 2%. Dental care use impacts on BP profiles independent of socioeconomic confounders, possibly through systemic inflammation. Regular dental visits may contribute to preventive medicine.

Helicobacter pylori(H. pylori) is an important pathogen in gastritis, peptic ulcer and possibly gastric cancer, but several questions remain unanswered. Particularly how the organism is transmitted and what is the relationship between oral presence of H. pyloriand the gastric infection. Accordingly, we aimed to characterize the H. pyloriin oral cavity and to evaluate its relationship to gastric H. pyloriinfection.
