Intensive periodontal interventions can reduce blood pressure (BP) and improve endothelial function in prehypertensive patients, according to results presented at the American Heart Association Scientific Sessions held November 11-15, 2017, in Anaheim, California.
In a single-blind randomized controlled trial (ClinicalTrials.gov identifier: NCT01917292), researchers enrolled 107 participants with prehypertension and moderate to severe periodontitis. The study participants were randomly assigned to receive either intensive periodontal treatment (n=53) or community-based periodontal care (n=54). Treatment duration was 4 weeks, and participants were followed for 6 months.
After 6 months, the periodontal inflamed surface area (PISA) was significantly improved in the intensive periodontal treatment group (P <.05). The intensive periodontal treatment group also saw a reduction in systolic and diastolic BP, as well as a decrease in high sensitivity C-reactive protein and interleukin-6 levels compared with the community-based care group.
The intensive treatment group also saw an improvement in flow-mediated vasodilation compared with the community-based care group.
Intensive periodontal treatment led to a reduction in BP, prevention of inflammation, and improvement in endothelial function. “Our data suggested that intensive periodontal therapy may be a novel prevention strategy to retard the transition of dental prehypertension to hypertension,” concluded the researchers.
