Impact of dental health intervention on cardiovascular metabolic risk: a pilot study of Japanese adults

Impact of Denture Use on Ischemic and Bleeding Outcomes of Patients with Acute Myocardial Infarction

Objective Oral diseases, including periodontitis and stomatitis, are highly prevalent worldwide and reportedly associated with the development of cardiovascular disease. Given the high rate of stomatitis in individuals wearing dentures, denture users may be at high risk of poor cardiovascular outcomes. We therefore investigated whether or not the use of dentures is associated with a poor clinical outcome in patients with acute myocardial infarction (MI). Methods This two-center retrospective observational study was conducted between January 2012 and March 2020. A total of 1046 patients with acute MI who underwent primary percutaneous coronary intervention were divided into two groups according to denture use status. The primary outcomes included ischemic events (cardiovascular death, recurrent MI, and ischemic stroke) and major bleeding (Bleeding Academic Research Consortium type 3 or 5). Results Of the 1046 patients with acute MI, 387 (37.0%) used dentures. An older age and prior MI were associated with an increased likelihood of denture use. During the mean 660-day follow-up period, ischemic and major bleeding events occurred in 169 (16.2%) and 102 (9.8%) patients, respectively. Denture use was associated with an increased risk of ischemic events, whereas no significant intergroup differences were observed in major bleeding outcomes. The results were similar among patients ≥75 years old. Conclusions More than one-third of the patients with acute MI wore dentures. Our findings suggest that denture use is significantly associated with an increased risk of ischemic events but not bleeding outcomes after acute MI.

Associations of oral hygiene with incident hypertension and type 2 diabetes mellitus: A population based cohort study in Southwest China

Oral health has been previously reported to be related with cardiovascular diseases (CVD). This study aimed to evaluate whether oral hygiene could reduce the risk of incident hypertension and type 2 diabetes mellitus (T2DM) in a population-based cohort. A total of 9280 people aged 18 years or above in Guizhou province were recruited from November 20th, 2010 to December 19th, 2012. Sociodemographic characteristics, lifestyles, anthropometric measurements, oral health status and care were collected by trained interviewers. The occurrences of hypertension and T2DM were ascertained until 2020. Cox proportional hazard models were used to evaluate the associations between oral hygiene and the occurrence of hypertension and T2DM, respectively. Compared with almost no tooth brushing, tooth brushing at least twice a day was associated with a 45% reduction (HR: .55; 95% CI: .42-.73) in hypertension events and reduced diabetes risk by 35% (HR: .65; 95% CI: .45-.94). For hypertension, those associations tended to be more pronounced in participants with Han ethic, or living in urban area, while those aged less than 60 or without baseline hypertension were more likely to have T2DM when they brush teeth less than twice a day. Frequent tooth brushing was associated with reduced risks of incident hypertension and T2DM. Tooth brushing at least twice a day may prevent future hypertension and T2DM events.
