New evidence finds an association between periodontal disease and stroke

Researchers from Boston University investigate the relationship between periodontal disease and ischemic stroke

People missing some or all of their teeth or who have significant loss of bone and tissue surrounding their teeth may be at an increased risk for having a stroke, according to a new study that appeared in the October issue of the Journal of Periodontology (JOP).

Researchers from Boston University investigated the relationship between periodontal disease and history of stroke in patients 60 years of age and older by examining the data of the Third National Health and Nutrition Examination Survey (NHANES III).

"We found that patients 60 years and older who were edentulous, partially edentulous and/or had significant clinical attachment loss were more likely to have a history of stroke compared to dentate adults without significant clinical attachment loss," said Dr. Martha E. Nunn, Goldman School of Dental Medicine, Boston University. "However, based on the results of this study, it is unclear whether periodontal disease is an independent risk factor for stroke or simply a risk marker that reflects negative effects of risk factors common to both periodontal disease and stroke."

Age, tobacco use, hypertension, diabetes, serum glucose, C-Reactive protein (CRP) and alcohol intake were also included as additional risk factors in this study. These confounders are independent risk factors for cardiovascular disease and if left untreated, periodontitis has been shown to have harmful effects on the control of diabetes, serum glucose levels and increases CRP levels.

Evidence continues to accumulate associating severe periodontitis with an increased risk of forming atherosclerotic plaques, which are responsible for myocardial infarction and ischemic stroke. According to past JOP studies, this relationship could be due to elevated CRP levels in patients with chronic periodontal disease.

Further investigation is needed to support periodontal treatment intervention as a means of controlling systemic inflammation. Based on findings from another study in this JOP issue, CRP levels may now be reduced by periodontal treatment such as scaling and root planing in patients with severe periodontal disease.

"Studies evaluating additional treatment methods such as repeated scaling and root planing or surgical treatment are needed to conclusively demonstrate that CRP can be improved by periodontal treatment," said Preston D. Miller, DDS and AAP president. "Until science presents a definitive direction, the periodontists ultimate goal is to lead patients to the right side of health. What we do know is that eliminating periodontal infection saves teeth."

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...

Im Focus: Glacier bacteria’s contribution to carbon cycling

Glaciers might seem rather inhospitable environments. However, they are home to a diverse and vibrant microbial community. It’s becoming increasingly clear that they play a bigger role in the carbon cycle than previously thought.

A new study, now published in the journal Nature Geoscience, shows how microbial communities in melting glaciers contribute to the Earth’s carbon cycle, a...
