ABSTRACT
INTRODUCTION: Periodontal disease (PD) and dental caries are oral infections leading to tooth loss that are associated with atherosclerosis and cerebrovascular disease. We assessed the hypothesis that PD and caries are associated with asymptomatic intracranial atherosclerosis (ICAS) in the Atherosclerosis Risk in Communities (ARIC) study. METHODS: Full-mouth clinical periodontal measurements (7 indices) collected at 6 sites per tooth from 6,155 subjects from the Dental Atherosclerosis Risk in Communities Study (DARIC) without prior stroke were used to differentiate seven PD stages (Periodontal Profile Class [PPC]-I to -VII) and dental caries on coronal dental surface (DS) and dental root surface (DRS). A stratified subset underwent 3D time-of-flight MR angiogram and 3D high isotropic-resolution black blood MRI. ICAS was graded according to the criteria established by the Warfarin-Aspirin Symptomatic Intracranial Disease (WASID) trial. We evaluated the relationship between PD stage and dental caries with asymptomatic ICAS, graded as no ICAS, <50% ICAS, and ≥50% ICAS. RESULTS: Among dentate subjects who underwent vascular imaging, 801 (70%) had no ICAS, 232 (20%) had <50% ICAS, and 112 (10%) had ≥50% ICAS. Compared to participants without gum disease (PPC-I), participants with mild-moderate tooth loss (PPC-VI), severe tooth loss (PPC-VII), and severe PD (PPC-IV) had higher odds of having <50% ICAS. Participants with extensive gingivitis (PPC-V) had significantly higher odds of having ≥50% ICAS. This association remained significant after adjusting for confounding variables: age, gender, race, hypertension, diabetes, dyslipidemia, 3-level education, and smoking status. There was no association between dental caries (DS and DRS) and ICAS <50% and ≥50%. CONCLUSION: We report significant associations between mild-moderate tooth loss, severe tooth loss, and severe PD with <50% ICAS as well as an association between extensive gingivitis and ≥50% ICAS. We did not find an association between dental caries and ICAS.

BACKGROUND AND PURPOSE: This study was undertaken to develop a patient-centered stroke outcome measure and initial validation of the proposed Young Stroke Questionnaire (YSQ). METHODS: This study assessed the reliability and discriminant validity of the YSQ. The initial questionnaire evolved from a focus group comprised of six young stroke survivors and six stroke neurologists centralized around four patient-centered domains. To determine the reliability and discriminant validity of the YSQ, 100 young stroke survivors were recruited and provided consent. Standardized clinical assessments completed included the modified Rankin Scale (mRS), National Institutes of Health Stroke Scale, and Stroke Impact Scale. Additionally, all patients were asked to complete the patient-centered YSQ. RESULTS: Of the 100 enrolled patients in the study (mean age ± standard deviation = 49 ± 11.3, 58% females, 53% African American, 44% White), Cronbach alpha for all domains was >0.7. Moreover, Cronbach alpha for entire questionnaire was >0.9, indicating that the scale, with four subdomains, is internally consistent and reproducible. Discriminant validity of the scale was assessed by comparing the means of each subdomain of the YSQ among healthy subjects to the groups of stroke patients as defined by the mRS. The YSQ was able to differentiate subjects with good outcome (mRS = 0-1) from subjects with varying degree of disability as defined by the mRS (p = 0.026). CONCLUSIONS: Standardized clinical assessments are not sensitive to disabilities in young stroke survivors. When compared to standardized clinical assessments, the YSQ is significantly capable of differentiating the young survivor perspective of the impact of stroke in all four subdomains.

OBJECTIVES: We investigated whether periodontal disease is associated with specific stroke subtype. MATERIALS AND METHODS: This is a single-center cross-sectional study. Periodontal disease was assessed in stroke and transient ischemic attack patients. Strokes caused by large-artery atherosclerosis were classified as intracranial atherosclerosis or extracranial atherosclerosis as well as anterior or posterior circulation disease. RESULTS: Consecutive patients (N=265) were enrolled (age 64 ± 12.8, 49% white, 46% black, and 56% male). A third (N=87) had moderately severe periodontal disease. Twenty percent (N=42) were strokes due to large-artery atherosclerosis. Large-artery strokes had a higher proportion of patients with periodontal disease than without periodontal disease (31% vs.16%, X2 p=0.01). There was also a higher proportion of patients with periodontal disease (12% vs. 5%) with stroke due to posterior circulation disease (crude odds ratio or OR 3.0, 95% CI 1.1-7.9, p=0.03), which persisted after adjustment for covariates (adjusted OR 3.1, 95% CI 1.04-9.1, p=0.004). Periodontal disease patients had a higher rate of large-artery stroke due to intracranial atherosclerosis compared to those without periodontal disease (20% vs. 8%; crude OR 2.6, 95% CI 1.3-5.6, p=0.01), and this association persisted after adjustment (adjusted OR 2.6, 95% CI 1.1-5.8, p=0.004). CONCLUSIONS: We report a higher proportion of stroke due to large-artery atherosclerosis in patients with periodontal disease compared to those without periodontal disease. We report an independent association between periodontal disease and intracranial atherosclerosis, as well as between periodontal disease and posterior circulation disease.
ABSTRACT
Multiple risk factors are associated with ischemic stroke. Here, we highlight studies indicating that periodontal disease significantly increases the risk of both primary ischemic stroke and subsequent cardiovascular events. Additionally, studies have shown an association between periodontal disease and multiple causes of ischemic stroke. Finally, we describe an ongoing clinical trial testing the benefit of periodontal disease treatment as a strategy to reduce risk for recurrent cardiovascular events in patients who have had recent ischemic stroke or transient ischemic attack. This article is mostly based on a presentation given in honor of Steven Offenbacher (1950 to 2018).
