AI Article Synopsis
- Periodontal disease, specifically lost teeth, is linked to an increased risk of stroke in a large international study involving over 26,000 participants from 32 countries.
- Symptoms like painful teeth and gums did not show a significant association alone, but combined symptoms increased the odds further.
- This research suggests that managing periodontal disease could be an important way to reduce stroke risk.
Article Abstract
Background: Periodontal disease may be an important modifiable risk factor for stroke.
Aims: To determine the contribution of markers of periodontal disease to stroke risk globally, within subpopulations, and by stroke subtypes.
Methods: INTERSTROKE is the largest international case-control study of risk factors for first acute stroke. All participants were asked a standardised set of questions about the presence or absence of painful teeth, painful gums or lost teeth, as markers of periodontal disease, within the previous year. The total number of reported variables was calculated per participant. Multivariable conditional logistic regression examined the association of these variables with acute stroke.
Results: In 26901 participants, across 32 countries, there was a significant multivariable association between lost teeth and stroke (OR 1.11, 95 % CI 1.01 - 1.22), but not painful teeth (OR 1.00, 95 % CI 0.91-1.10) or painful gums (OR 1.01, 95 % CI 0.89 - 1.14). When these symptoms were considered together there was a graded increased odds of stroke, with the largest magnitude of association seen if a patient reported all three of painful teeth, painful gums and lost teeth (OR 1.34, 95 % CI 1.00 - 1.79).
Conclusions: Our findings suggest that features of severe periodontal disease are a risk factor for acute stroke. Periodontal disease should be considered as a potentially modifiable risk factor for stroke.

Diabetes exacerbates periodontitis by overexpressing reactive oxygen species (ROS), which leads to periodontal bone resorption. Consequently, it is imperative to relieve inflammation and promote alveolar bone regeneration comprehensively for the development of diabetic periodontal treatment strategies. Furthermore, an orderly treatment to avoid interference between these two processes can achieve the optimal therapeutic effect.

The progression of periodontal disease (PD) involves the action of oxidative stress mediators. Antioxidant agents may potentially attenuate the development of this condition. Thus, we aimed to evaluate the effects of different doses of humic acid (HA), extracted from biomass vermicomposting, on redox status and parameters related to PD progression in rats.

This study investigated the effect of low-intensity pulsed ultrasound (LIPUS) on the therapeutic efficacy of EVs derived from periodontal ligament stem cells (PDLSCs) and preliminarily explored its mechanism. PDLSCs were cultured with osteogenic media and stimulated with or without LIPUS, and then EVs and LIPUS-stimulated EVs (L-EVs) were isolated separately.

Over the past few decades, dental implants have been successfully utilized to replace teeth lost due to periodontal disease and other conditions. However, similar to natural teeth, dental implants are vulnerable to inflammatory peri-implant diseases, which can compromise their long-term viability. This review aims to summarize the current understanding of peri-implant diseases and discuss effective strategies for their diagnosis, treatment, and long-term management.
