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: The “TRiC” to folding actin

Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.

Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
