Carotid Artery Calcification Detected on Panoramic Radiography Is Significantly Related to Cerebrovascular Accident, Coronary Artery Disease, and Poor Oral Health: A Retrospective Cross-Sectional Study. Dent J (Basel) 2024; 12:99. [PMID: 38668011 PMCID: PMC11049454 DOI: 10.3390/dj12040099] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2024] [Revised: 03/31/2024] [Accepted: 04/08/2024] [Indexed: 04/28/2024] Open
Abstract
Panoramic radiography imaging modality is widely used by dentists for diagnosing dental and jaw conditions. It can also detect carotid artery calcification (CAC), indicative of calcified atherosclerotic plaques in the carotid arteries. This cross-sectional retrospective study at the University of Tennessee Health Science Center investigated the link between CAC identified on panoramic radiograph (PR) and cerebrovascular accident (CVA), coronary artery disease (CAD), and poor oral health. Data from 314 CAC patients collected from 2014 to 2023 included age at diagnosis, gender, and clinical histories of hypertension, hyperlipidemia, diabetes mellitus, CVA, CAD, and the decay, missing, and filled permanent teeth (DMFT) index. These patients were age- and gender-matched with non-CAC patients for analysis. The findings revealed high prevalences of hypertension (86.2%), hyperlipidemia (57.6%), diabetes mellitus (30.7%), CVA (15.5%), and CAD (28.7%) amongst CAC patients and the average DMFT index was 26.6. A comparative analysis of 276 matched controls demonstrated significant differences in hypertension (85.9% vs. 57.6%), hyperlipidemia (58.3% vs. 33.7%), diabetes (32.6% vs. 22.1%), CVA history (14.9% vs. 5.1%), CAD (26.1% vs. 9.8%), and DMFT scores (26.3 vs. 23.7), all indicating strong associations between CAC and these health conditions. The adjusted analysis showed that hypertension (aOR: 3.20 [95% CI: 2.06-5.07]), hyperlipidemia (aOR: 1.70 [95% CI: 1.14-2.50]), CVA (aOR: 2.20 [95% CI: 1.13-4.30]), and CAD (aOR: 2.10 [95% CI: 1.28-3.60]) were significantly associated with CAC. Notably, only 41.7% of the patients received a medical consultation after CAC detection on PR. It is crucial for dentists to refer patients for further evaluation.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:8139. [PMID: 35805797 PMCID: PMC9265665 DOI: 10.3390/ijerph19138139] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 06/20/2022] [Revised: 06/22/2022] [Accepted: 06/29/2022] [Indexed: 02/01/2023]
Abstract
Periodontitis is a multifactorial disease causing inflammatory destruction of supporting structures of the dentition and eventually leading to its loss. This study was designed to evaluate common risk factors for periodontitis and acute coronary syndrome in the study population and demonstrate the systemic impact of periodontitis on the occurrence of acute coronary syndrome. A total of 160 patients (35 female and 125 male) were enrolled in the study. Considering the age range, the largest group of patients (118 patients) was between 55 and 65 years, which accounted for 73.8% of the total study population. There were 35 patients (21.9%) in the age group of 45 to 54 years, while the youngest age group of 35 to 44 years had as many as seven patients. Medical history and physical examination, including periodontal status, were performed. API, PD, CAL, and CPITN were evaluated. Common risk factors for periodontitis and acute coronary syndrome were assessed. The study assessed risk factors such as hypertension, diabetes, dyslipidemia, general health, smoking, height, weight, and hip circumference. In light of the above-described etiopathogenesis of atherosclerotic disease and its association with periodontal disease, it is important to emphasize preventing and treating periodontitis, especially in patients in the so-called high-risk group for cardiovascular disease. Dentists' introduction of an appropriate prophylactic and therapeutic plan may constitute both primary and secondary prevention of cardiovascular diseases.

Risk Assessment of Cnm-Positive Streptococcus mutans in Stroke Survivors (RAMESSES): Protocol for a Multicenter Prospective Cohort Study. Front Neurol 2022; 13:816147. [PMID: 35645961 PMCID: PMC9133813 DOI: 10.3389/fneur.2022.816147] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2021] [Accepted: 04/19/2022] [Indexed: 11/13/2022] Open
Abstract
Introduction The role of commensal microbiota in systemic diseases, including brain diseases, has attracted increasing attention. Oral infectious diseases, such as dental caries and periodontitis, are also involved in cerebrovascular diseases and cognitive impairment. Cerebral microbleeds (CMBs) and intracerebral hemorrhage due to small vessel disease (SVD), are presumably associated with a high risk of vascular cognitive impairment and stroke. We previously reported that Streptococcus mutans (S. mutans, the main pathogen of dental caries), harboring the cnm gene that encodes the collagen-binding protein Cnm, is associated with the development of hypertensive intracerebral hemorrhage and aggravation of CMBs. We also proposed a mechanism by which the circulating Cnm-expressing S. mutans causes intracerebral hemorrhage or CMBs; it binds to denuded basement membranes mainly composed of collagen IV through damaged tight junctions or it directly invades endothelial cells, resulting in blood-brain barrier injury. In November 2018, we initiated a multicenter, prospective cohort study (RAMESSES: Risk Assessment of Cnm-positive S. mutans in Stroke Survivors; UMIN Clinical Trials Registry: UMIN000045559) to explore the longitudinal association between Cnm-positive S. mutans and CMBs with comprehensive dental findings, which should determine the effect of Cnm-positive S. mutans in the oral cavity on the risk of CMB development and cognitive decline. Methods Fifteen domestic institutes will be enlisted to enroll 230 patients who have at least one CMB in the deep brain area and develop a stroke within the past year. The prevalence of Cnm-positive S. mutans based on oral specimens and dental hygiene will be examined. The primary outcome is the number of newly developed deep CMBs. The secondary outcomes include the new development of lobar, subtentorial, or any type of CMBs; symptomatic intracerebral hemorrhage or ischemic stroke; changes in cognitive function or frailty; major bleeding; all-cause mortality; and antibody titers against periodontal pathogens. The observation period will be 2 years. Discussion The 2-year longitudinal prospective cohort study is expected to establish the role of Cnm-positive S. mutans in SVD including CMBs and intracerebral hemorrhage from the perspective of the “brain-oral axis” and provide guidance for novel prophylactic strategies against Cnm-positive S. mutans-induced SVD.

Abstract
BACKGROUND Acute infection/inflammation increases the risk of acute vascular events (AVEs). Invasive dental treatments (IDTs) trigger short-term acute inflammation. PURPOSE The aim of this work is to critically appraise the evidence linking IDTs and AVEs. DATA SOURCES Six bibliographical databases were searched up to 31 August 2021. A systematic review following PRISMA guidelines was performed. STUDY SELECTION Intervention and observational studies reporting any AVEs following IDT were included. DATA EXTRACTION Two reviewers independently extracted data and rated the quality of studies. Data were pooled using fixed-effect, inverse variance weights analysis. RISK OF BIAS Risk of bias was assessed by the Newcastle-Ottawa Quality Assessment Scale for observational studies and the Cochrane Handbook-Rob 2.0 for randomized controlled trials. DATA SYNTHESIS In 3 out of 16 clinical studies, a total of 533,175 participants, 124,344 myocardial infarctions, and 327,804 ischaemic strokes were reported. Meta-analysis confirmed that IDT did not increase incidence ratios (IR) for combined vascular events either at 1-4 weeks (IR of 1.02, 95% CIs: 0.92 to 1.13) and at 5-8 weeks (IR of 1.04, 95% CIs: 0.97 to1.10) after treatment. LIMITATIONS A high level of heterogeneity (study designs and time point assessments) was found. CONCLUSION Patients who received IDT exhibited no substantial increase in vascular risk over 8 weeks post treatment.

Association between internal carotid artery calcifications detected as incidental findings and clinical characteristics associated with atherosclerosis: A dental volumetric tomography study. Eur J Radiol 2021; 145:110045.

Abstract
PURPOSE To evaluate the presence of calcifications in the internal carotid artery (ICA) in cone-beam computed tomography (CBCT), and to verify the association of these findings with sex, age, dental condition, and risk factors associated with vascular disorders. METHODS The CBCT scans used in this study were obtained from the database of a private dental clinic requested for the planning of rehabilitation with dental implants. The selection criteria were patients aged 40 years and above. Out of a pool of 1176 CBCT examinations, a total of 284 scans of adult patients were evaluated by two blinded observers. Data were collected from patients' medical records. RESULTS ICA calcifications were present in 63.0% of the examinations. Most calcifications were in the intracranial pathway (166). Despite being present in a smaller number 57 (C1), extracranial calcifications were more severe. Spearman's ρ coefficients (rS) indicated that the number of missing teeth was directly associated with the presence of calcifications (p = 0.042) and severity (p = 0.020). The age variable also had a direct relationship with the presence of calcifications (p ≤ 0.0001), increasing its frequency and severity over the years. In addition, hypertension (p = 0.036) and use of antihypertensive drugs (p = 0.015) were directly associated. CONCLUSIONS There is a high occurrence of ICA calcifications in CBCT as incidental findings in adult patients, and it is directly associated with age, number of missing teeth and hypertension.

Association between Oral Pathology, Carotid Stenosis, and Oral Bacterial DNA in Cerebral Thrombi of Patients with Stroke. Stroke Res Treat 2021; 2021:5402764.

Abstract
Methods Thrombus aspirates and control arterial blood were taken from 71 patients (70.4% male; mean age, 67.4 years) with acute ischemic stroke. Tooth pathology was registered using CT scans. Carotid stenosis was estimated with CTA and ultrasonography. The presence of bacterial DNA from aspirated thrombi was determined using quantitative PCR. We also analyzed the presence of these bacterial DNAs in carotid endarterectomies from patients with peripheral arterial disease. Results Bacterial DNA was found in 59 (83.1%) of the thrombus aspirates (median, 8.6-fold). Oral streptococcal DNA was found in 56 (78.9%) of the thrombus aspirates (median, 5.1-fold). DNA from A. actinomycetemcomitans and P. gingivalis was not found. Most patients suffered from poor oral health and had in median 19.0 teeth left. Paradoxically, patients with better oral health had more oral streptococcal DNA in their thrombus than the group with the worst pathology (p = 0.028). There was a trend (OR 7.122; p = 0.083) in the association of ≥50% carotid artery stenosis with more severe dental pathology. Oral streptococcal DNA was detected in 2/6 of carotid endarterectomies. Conclusions Stroke patients had poor oral health which tended to associate with their carotid artery stenosis. Although oral streptococcal DNA was found in thrombus aspirates and carotid endarterectomy samples, the amount of oral streptococcal DNA in thrombus aspirates was the lowest among those with the most severe oral pathology. These results suggest that the association between poor oral health and acute ischemic stroke is linked to carotid artery atherosclerosis.

Abstract
The aim of this scoping review was to determine health-related impacts of poor oral health among community-dwelling seniors. Using MeSH terms and keywords such as elderly, general health, geriatrics, 3 electronic databases-Medline, CINAHL, and Age Line were searched. Title and abstracts were independently screened by 3 reviewers, followed by full-texts review. A total of 131 articles met our inclusion criteria, the majority of these studies were prospective cohort (77%, n = 103), and conducted in Japan (42 %, n = 55). These studies were categorized into 16 general health outcomes, with mortality (24%, n = 34), and mental health disorders (21%, n = 30) being the most common outcomes linked with poor oral health. 90% (n = 120) of the included studies reported that poor oral health in seniors can subsequently lead to a higher risk of poor general health outcomes among this population. Improving access to oral healthcare services for elderly can help not only reduce the burden of oral diseases in this population group but also address the morbidity and mortality associated with other general health diseases and conditions caused due to poor oral health. Findings from this study can help identify shortcomings in existing oral healthcare programs for elderly and develop future programs and services to improve access and utilization of oral care services by elderly.

Abstract
Objectives Periodontal disease and tooth loss were found to be associated with several peripheral vascular disorders. Nonetheless, an evaluation of the literature on the broader domains of oral health in individuals with peripheral vascular disorders is lacking. This systematic review aims to collate the current evidence on the oral health status of individuals with peripheral vascular disorders. Methods Five electronic databases were searched for studies assessing oral health parameters in individuals with peripheral vascular disorders. Outcome measures considered were periodontal health, dentition status, caries indices, oral prostheses, oral pathologies and oral hygiene behaviours. The Newcastle-Ottawa scale was used to appraise the quality of the studies. Results From 3025 records identified, 24 studies involving 1232 participants with peripheral vascular disorders were included in this review. In nine studies, periodontitis was significantly more prevalent in peripheral vascular disorders compared to non-peripheral vascular disorders participants. A further six studies reported individuals with peripheral vascular disorders also had significantly fewer teeth and increased rates of edentulism. Only one study reported a higher incidence of dental caries in peripheral vascular disorders participants. Other aspects of oral health such as oral prosthesis, oral pathology and oral hygiene behaviours were seldom assessed. Conclusions The scarcity of studies reporting on broader domains limited our ability to arrive at a conclusion regarding the oral health status of individuals with peripheral vascular disorders. Future studies ought to assess these domains in individuals with peripheral vascular disorders and controls to gain a more complete understanding of oral health and its potential association with peripheral vascular disorders.

Abstract
The association between invasive dental treatments (IDTs) and a short-term risk of myocardial infarction (MI) and ischemic stroke (IS) remains controversial. Bacterial dissemination from the oral cavity and systemic inflammation linked to IDT can induce a state of acute vascular dysfunction. The aim of study is to investigate the relation of IDTs to MI and IS by using case-only study designs to analyze data from a large Taiwanese cohort. A nationwide population-based study was undertaken by using the case-crossover and self-controlled case series design to analyze the Taiwanese National Health Care Claim database. Conditional logistic regression model and conditional Poisson regression model were used to estimate the risks of MI/IS. In addition, we used burn patients as negative controls to explore the potential effect of residual confounding. In total, 123,819 MI patients and 327,179 IS patients in the case-crossover design and 117,655 MI patients and 298,757 IS patients were included in the self-controlled case series design. Results from both study designs showed that the risk of MI within the first 24 wk after IDT was not significantly different from or close to unity except for a modest risk during the first week for patients without other comorbidities (odds ratios [95% confidence intervals] of 1.31 [1.08-1.58] and 1.15 [1.01-1.31] for 3 d and 7 d, respectively). We also observed no association between IDTs and IS, or the risk ratio was close to unity. IDTs did not appear to be associated with a transient risk of MI and IS in the Taiwanese population, with consistent findings from both case-only study designs. However, we cannot exclude that dental infections and diseases may yield a long-term risk of MI and IS.

Abstract
OBJECTIVE To develop an oral hygiene complex intervention and evaluate its feasibility in a single UK stroke centre. BACKGROUND Oral hygiene interventions might improve clinical outcomes after stroke but evidence-based practice is lacking. MATERIALS AND METHODS We used a sequential mixed methods approach and developed an oral hygiene complex intervention comprising: (i) web-based education and 'hands-on' practical training for stroke unit nursing staff, (ii) a pragmatic oral hygiene protocol consisting of twice-daily powered (or manual if preferred) brushing with chlorhexidine gel (or non-foaming toothpaste) ± denture care. We evaluated feasibility of (i) the staff education and training and (ii) the oral hygiene protocol in consenting inpatients with confirmed stroke, requiring assistance with at least one aspect of personal care. RESULTS The staff education and training were feasible, acceptable and raised knowledge and awareness. Several barriers to completing the education and training were identified. The oral hygiene protocol was feasible and well-tolerated. 22% of eligible patients screened declined participation in the study. Twenty-nine patients (median age = 78 year; National Institutes of Health Stroke Scale score = 8.5; 73% dentate) were recruited at a median of 7 days from stroke onset. 97% of participants chose the default chlorhexidine-based protocol; the remainder chose the non-foaming toothpaste-based protocol. The mouth hygiene protocol was administered as prescribed on 95% of occasions, over a median duration of 28 days. There were no adverse events attributed to the oral hygiene protocol. CONCLUSION Our oral hygiene complex intervention was feasible in a single UK stroke centre. Further studies to optimise patient selection, model health economics and explore efficacy are now required.

Abstract
There is strong epidemiological association between periodontal disease and cardiovascular disease but underlying mechanisms remain ill-defined. Because the human periodontal disease pathogen, Porphyromonas gingivalis (Pg), interacts with innate immune receptors Toll-like Receptor (TLR) 2 and CD36/scavenger receptor-B2 (SR-B2), we studied how CD36/SR-B2 and TLR pathways promote Pg-mediated atherosclerosis. Western diet fed low density lipoprotein receptor knockout (Ldlr°) mice infected orally with Pg had a significant increase in lesion burden compared with uninfected controls. This increase was entirely CD36/SR-B2-dependent, as there was no significant change in lesion burden between infected and uninfected Ldlr° mice. Western diet feeding promoted enhanced CD36/SR-B2-dependent IL1β generation and foam cell formation as a result of Pg lipopolysaccharide (PgLPS) exposure. CD36/SR-B2 and TLR2 were necessary for inflammasome activation and optimal IL1ß generation, but also resulted in LPS induced lethality (pyroptosis). Modified forms of LDL inhibited Pg-mediated IL1ß generation in a CD36/SR-B2-dependent manner and prevented pyroptosis, but promoted foam cell formation. Our data show that Pg infection in the oral cavity can lead to significant TLR2-CD36/SR-B2 dependent IL1ß release. In the vessel wall, macrophages encountering systemic release of IL1ß, PgLPS and modified LDL have increased lipid uptake, foam cell formation, and release of IL1ß, but because pyroptosis is inhibited, this enables macrophage survival and promotes increased plaque development. These studies may explain increased lesion burden as a result of periodontal disease, and suggest strategies for development of therapeutics.

Periodontal disease in relation to selected parameters of the cardiovascular system in a group of patients with stable angina pectoris. Cent Eur J Immunol 2014; 39:181-6. [PMID: 26155121 PMCID: PMC4440030 DOI: 10.5114/ceji.2014.43720] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2013] [Accepted: 05/05/2014] [Indexed: 12/02/2022] Open
Abstract
Introduction Periodontal diseases (PD), which are the cause of chronic inflammatory processes, can develop increased susceptibility to vascular diseases through atherosclerosis. Due to the raised inflammatory and thrombotic risk, PD can have a significant influence on the course and results of stable angina pectoris (SAP). Objectives The aim of the study is to evaluate the influence of chosen PD parameters on selected cardiovascular system parameters, and the correlation between chosen parameters of periodontitis and cardiovascular system parameters. Material and methods The case group included 67 patients with SAP, ≤ 60 years of age. The occurrence of well-known cardiovascular disease risk factors was evaluated on the basis of the clinical interview, clinical examination and laboratory tests. The occurrence of known risk factors for cardiovascular diseases (CVD) was established on the basis of the interview, clinical research and laboratory tests. Periodontal examination included API (approximal plaque index), CAL (clinical attachment level), PD (pocket depth), and BI (bleeding index). IMT (intima-media thickness) and the size of atherosclerotic plaque in carotid arteries were assessed by ultrasound examination. Segmental contractility abnormalities were assessed on the basis of echocardiography examination, presence of the single-vessel vascular and multi-vessel vascular disease on the basis of angiographic examination. Results In the study group of patients, numerous risk factors and a higher level of API, CAL, PD and BI were observed. A higher prevalence of multi-vessel disease (75%) than single-vessel disease (25%) was noted on the basis of angiographic examination. Patients with contractility abnormalities demonstrated also poor oral cavity health. In addition, a higher concentration of CRP (3.2 mg/dl), fibrinogen (3.3 g/l)) and the progression of atherosclerosis, e.g. increased IMT (2.1 mm) and formation of atherosclerotic plaques were noted. Results of multivariate logistic regression demonstrated that API and PD had a significant influence on IMT. In patients with BMI ≥ 30 kg/m2, the risk of increased IMT (OR = 4.67) was fourfold higher. Summary Periodontitis may influence the occurrence and course of the atherosclerotic process in persons with stable angina.

Abstract
Studies have suggested an association between clinical/subclinical atherosclerosis and periodontal status. The purpose of this study was to investigate the association among maximal carotid intima-media thickness (cIMT), atherosclerotic plaque, and periodontal status in Chinese elderly patients. A cross-sectional study was conducted of 847 participants (age, 70.64 ± 9.03 yr) with ≥10 teeth. A questionnaire survey, routine biochemical tests, a periodontal examination, and maximal cIMT measurement were performed for each. Traditional risk factors for atherogenesis were considered in the statistical analysis. Mean plaque index, which reflects oral hygiene, was correlated with maximal cIMT and atherosclerotic plaque in the study sample overall (β = 0.068, p < .001; OR = 2.051, p < .001) and in euglycemic participants (β = 0.066, p = .008; odds ratio = 2.122, p = .009). In hyperglycemic participants, multiple linear regression analysis (p = .006) and multivariate logistic regression analysis (p = .025) revealed a linear and dose-dependent association between mean clinical attachment loss and maximal cIMT after adjustment for traditional risk factors. Each 1-mm increase in mean clinical attachment loss corresponded to a 0.018-mm increase in maximal cIMT. The risk of atherosclerotic plaque increased by 18.3% with each 1-mm increase in mean clinical attachment loss. Other indicators of periodontal exposure, including percentage of sites with attachment loss ≥ 3 to 5 mm (3%-5%), were also correlated with cIMT and atherosclerotic plaque in hyperglycemic patients. In this elderly population, a linear and dose-dependent association among mean clinical attachment loss, attachment loss 3% to 5%, maximal cIMT, and atherosclerotic plaque was verified in those with hyperglycemia. Poor oral hygiene was correlated with maximal cIMT and atherosclerotic plaque in all participants, including those with normal blood glucose.

Abstract
OBJECTIVES The purpose of this study was to test whether high-dose statin treatment would result in a reduction in periodontal inflammation as assessed by (18)F-fluorodeoxyglucose positron emission tomography (FDG-PET)/computed tomography (CT). BACKGROUND Periodontal disease (PD) is an independent risk factor for atherosclerosis. METHODS Eighty-three adults with risk factors or with established atherosclerosis and who were not taking high-dose statins were randomized to atorvastatin 80 mg vs. 10 mg in a multicenter, double-blind trial to evaluate the impact of atorvastatin on arterial inflammation. Subjects were evaluated using FDG-PET/CT at baseline and at 4 and 12 weeks. Arterial and periodontal tracer activity was assessed while blinded to treatment allocation, clinical characteristics, and temporal sequence. Periodontal bone loss (an index of PD severity) was evaluated using contrast-enhanced CT images while blinded to clinical and imaging data. RESULTS Seventy-one subjects completed the study, and 59 provided periodontal images for analysis. At baseline, areas of severe PD had higher target-to-background ratio (TBR) compared with areas without severe PD (mean TBR: 3.83 [95% confidence interval (CI): 3.36 to 4.30] vs. 3.18 [95% CI: 2.91 to 3.44], p = 0.004). After 12 weeks, there was a significant reduction in periodontal inflammation in patients randomized to atorvastatin 80 mg vs. 10 mg (ΔTBR 80 mg vs. 10 mg group: mean -0.43 [95% CI: -0.83 to -0.02], p = 0.04). Between-group differences were greater in patients with higher periodontal inflammation at baseline (mean -0.74 [95% CI: -1.29 to -0.19], p = 0.01) and in patients with severe bone loss at baseline (-0.61 [95% CI: -1.16 to -0.054], p = 0.03). Furthermore, the changes in periodontal inflammation correlated with changes in carotid inflammation (R = 0.61, p < 0.001). CONCLUSIONS High-dose atorvastatin reduces periodontal inflammation, suggesting a newly recognized effect of statins. Given the concomitant changes observed in periodontal and arterial inflammation, these data raise the possibility that a portion of that beneficial impact of statins on atherosclerosis relate to reductions in extra-arterial inflammation, for example, periodontitis.

Abstract
Objectives Chronic apical periodontitis (CAP) appears to be a risk factor for coronary heart disease. The aims of the study were to estimate the significance of AP for the atherosclerotic burden and to examine the potential effect of endodontic treatment. Materials and methods The whole-body computed tomography (CT) examinations of 531 patients with a mean age of 50 ± 15.7 years were evaluated retrospectively. The atherosclerotic burden of the abdominal aorta was quantified using a calcium scoring method. The parameters of periodontitis were measured using the CT scan. Results The patients had a total of 11,191 teeth. The volume of the aortic atherosclerotic burden for patients with at least one CAP lesion was 0.32 ± 0.92 ml, higher than for patients with no CAP (0.17 ± 0.51 ml; p < 0.05). The atherosclerotic burden increased with age and number of CAP lesions without root canal treatment, but not with number of CAP lesions with endodontic treatments (p < 0.05 each). In logistic regression models, age (Wald 90.8), CAP without endodontic treatment (Wald 39.9), male gender (Wald 9.8), and caries per tooth (Wald 9.0) correlated positively and the number of fillings (Wald 11) correlated negatively with the atherosclerotic burden (p < 0.05 each). Apical radiolucencies in teeth with endodontic treatment were irrelevant with respect to atherosclerosis. Conclusions CAP correlated positively with the aortic atherosclerotic burden. In regression models, CAP without endodontic treatment was found to be an important factor, not however apical radiolucencies in teeth with endodontic treatment. Clinical relevance Further research is needed to clarify the possible clinical significance of these associations.

Abstract
Purpose The aim of this study was to evaluate whether poor oral hygiene is associated with carotid and popliteal arterial intima–media thickness, which is one of the predictors of future progression of sub-clinical atherosclerosis, and high-sensitivity C-reactive protein (hsCRP) and fibrinogen levels. Methods A specialised dentist checked the patients and selected 550 patients during periodontal examinations, according to their oral hygiene. The patients had no history of atherosclerotic disease. Carotid and popliteal artery B-mode ultrasonographic examinations and hsCRP and fibrinogen levels were analysed at baseline and after a mean of 6.2 months. The patients were scored on the DMFT index for the number of decayed (D), missing (M), and filled (F) teeth (T). We also used the Silness-Loe plaque index (SLI) to evaluate oral hygiene and dental plaque. The patients were divided into two groups using the DMFT and SLI criteria. Group I had a DMFT index score from 0 to 3 and SLI index score of 0 or 1. Group II had a DMFT index score from 4 to 28 and SLI index score of 2 or 3. Results A significant association was observed between dental status, oral hygiene, carotid and popliteal artery intima–media thickness and hsCRP level. Patients with increasing DMFT and SLI scores correlated with increasing carotid artery intima–media thickness. Conclusions The results clearly showed that chronic poor oral hygiene and tooth loss are related to sub-clinical atherosclerotic changes in the carotid arteries and may be indicative of future progression of atherosclerosis.

Abstract
OBJECTIVE Previous studies have suggested that marginal periodontitis is a risk factor for developing atherosclerosis. The objective of this study was to determine whether caries may also be associated with atherosclerosis. METHODS The computed tomography data sets of 292 consecutive patients, 137 women and 155 men with a mean age of 54.1±17.3 years, were analyzed. Caries were quantified based on the number of decayed surfaces of all the teeth, and periodontitis was quantified on the basis of the horizontal bone loss in the jaw. The presence of chronic apical periodontitis (CAP) was assessed, and the aortic atherosclerotic burden was quantified using a calcium scoring method. RESULTS The patients with <1 caries surfaces/tooth had a lower atherosclerotic burden (0.13±0.61 mL) than patients with ≥1 caries surfaces/tooth. The atherosclerotic burden was greater in patients with a higher number of lesions with pulpal involvement and more teeth with chronic apical periodontitis. In the logistical regression models, age (Wald 49.3), number of caries per tooth (Wald 26.4), periodontitis (Wald 8.6), and male gender (Wald 11) were found to be independent risk factors for atherosclerosis. In the linear regression analyses, age and the number of decayed surfaces per tooth were identified as influencing factors associated with a higher atherosclerotic burden, and the number of restorations per tooth was associated with a lower atherosclerotic burden. CONCLUSION Dental caries, pulpal caries, and chronic apical periodontitis are associated positively, while restorations are associated inversely, with aortic atherosclerotic burden. Prospective studies are required to confirm these observations and answer the question of possible causality.

Abstract
BACKGROUND Associations between mastication and insufficient nutrient intake, obesity, and glucose metabolism have been shown in previous studies. However, the association between mastication and diabetes has not been clarified. Our objective was to examine the association between mastication, namely masticatory performance or rate of eating, and diabetes in a population-based cohort. METHODS We conducted a cross-sectional study of the association between mastication and diabetes in the Nagahama Prospective Cohort Study, an ongoing study which recruits citizens of Nagahama City in Shiga Prefecture, central Japan. 2,283 male and 4,544 female residents aged 40-74 years were enrolled from July 2009 to November 2010. Masticatory performance was evaluated by spectrophotometric measurement of color changes after masticating color-changeable chewing gum. Categorical rate of eating (fast, intermediate or slow) was self-assessed using a questionnaire. RESULTS 177 males (7.7%) and 112 (2.4%) females were diagnosed with diabetes. We divided participants into four groups by quartile of masticatory performance, namely Q1 (lowest), 2, and 3 and 4 (highest). Compared to the lowest performance group, the multivariable adjusted odds ratio (OR) of diabetes was 0.91 (95% confidence interval (CI), 0.58-1.4) in Q2, 0.77 (95% CI, 0.48-1.2) in Q3, and 0.53 (95% CI, 0.31-0.90) in the highest group in males, and 1.2 (95% CI, 0.73-2.0), 0.95 (95% CI, 0.54-1.6) and 0.56 (95% CI, 0.30-1.0) in females. We also estimated ORs of diabetes by rate of eating. Compared to the fast eating group, ORs in males were 0.87 (95% CI, 0.61-1.2) in the intermediate group and 0.38 (95% CI, 0.16-0.91) in the slow group, and ORs in females were 0.92 (95% CI, 0.59-1.4) and 1.5 (95% CI, 0.73-3.0). CONCLUSIONS These findings support the hypothesis that higher masticatory performance and slow eating prevent the occurrence of diabetes.

Abstract
AIM In patients affected by periodontal disease, hypertension and systemic inflammation might cause an arterial hemodynamic derangement; this, in turn, can act as a mediator of the atherogenic process often seen in these patients. This study aimed at a comprehensive hemodynamic evaluation in periodontal patients. METHODS Fourty-eight subjects participating to a cardiovascular prevention programme were enrolled. Periodontitis, classical risk factors for atherosclerosis, and shear and tensile forces in both carotid and brachial arteries were evaluated. Calculated periodontal indexes were plaque, gingival and pocket deep (PD) indexes. Simple and multiple regression analyses were performed. Afterwards, 30 of them with normal PD index were compared with 30 carefully - matched patients with periodontitis. RESULTS Brachial and carotid parietal tension were significantly associated with periodontal indexes, especially PD-Sum, in both simple (r = 0.42, p < 0.001 for carotid artery and r = 0.36, p < 0.02 for brachial artery) and multiple regression analyses. Shear stress gave similar results. In case-control analysis, shear stress was lower by 15% and 30%, respectively, in carotid and brachial artery in patients with high PD; common carotid parietal tension was higher. Arterial stiffness resulted not associated with periodontitis. CONCLUSIONS Periodontal disease is associated to a complex atherosclerotic prone hemodynamic derangement, particularly in large elastic arteries.

Abstract
Parkinson's disease (PD) is a progressive neurodegenerative disorder related to the loss or absence of dopaminergic neurons in the brain. These deficits result in slowness of movement, tremor, rigidity, and dysfunction of behaviour. These symptoms negatively influence the patient's capability to carry out the daily oral hygiene manoeuvres. The aim of this work is to record the oral health condition of PD patients evaluated at the IRCSS Bonino-Puleio in Messina. The oral health of 45 consecutive PD patients (study group) with neurologic diagnosis based on United Kingdom Brain Bank Criteria has been compared with that of another 45 no PD patients of the same age (control group). The evaluation of the general oral condition was recorded underlining tooth loss, active periodontal disease, and presence of untreated caries. The frequency of untreated caries, periodontal diseases, and missing teeth of the study group was significantly higher than in control group. Based on the data results, clinicians should direct high attention to the oral hygiene of patients with PD, above all at the early stages of the caries or periodontal disease, in order to prevent serious evolution of those pathologic dental conditions that may finally result in the tooth extraction event.

Abstract
A associação entre doença periodontal e o desenvolvimento de aterosclerose tem sido pesquisada. Esta revisão sistemática da literatura se propõe a verificar a associação entre a doença periodontal e a aterosclerose subclínica. A pesquisa utilizou as bases de dados: PubMed, Scopus, LILACS, BBO, Biblioteca Cochrane e Scielo com os termos: "doença periodontal", "periodontite", "carótida" e "aterosclerose". Foram excluídos artigos: que apresentaram resumos escritos em idiomas diferentes do português, inglês e espanhol; com abordagem laboratorial em modelos experimentais; sem descrição ou referência a estimadores de associação entre doença periodontal e aterosclerose subclínica; pesquisas que realizaram a medida da doença periodontal por parâmetros diferentes de exames clínicos; pesquisas que não analisaram a espessura da íntima média da artéria carótida através de exame de ultrassom; e que abordassem grupos específicos. Foram comparados os desenhos de estudo, protocolos de medida e os dados relatados. De um total de 63 referências, apenas 10 artigos contemplavam todos os critérios de inclusão, distribuídos em: 1 estudo longitudinal, 6 transversais e 3 casos controles. Observou-se uma heterogeneidade entre os estudos em relação ao método de mensuração da doença periodontal e os desfechos da aterosclerose. Concluiu-se que infecções periodontais são fortemente associadas ao desenvolvimento da aterosclerose subclínica, entretanto os mecanismos envolvidos no processo patogênico ainda permanecem desconhecidos.

Abstract
The purpose of this cross-sectional study was to investigate the association of periodontitis and/or tooth loss with hypertension by excluding the common confounders. Eighty-one Tanzanian women who were aged 46-58 years, nonsmokers, nonalcoholic drinkers, and on no medication underwent clinical examination. Multiple-regression analysis showed that the severity of periodontitis was significantly correlated with increased systolic blood pressure and diastolic blood pressure. Simple-regression analysis indicated that the severity of periodontitis was inversely correlated with 24-hour urinary excretion of potassium (r = -0.579, P = 0.0004) and also inversely with the frequency of intakes of green vegetables (r = -0.232, P = 0.031) and fruits (r = -0.217, P = 0.0043). Low-potassium intake in the diet mostly accompanied by low dietary fiber intake increases BP as well as periodontal inflammation. Potassium intake may be an important factor linking periodontitis and hypertension in middle-aged nonsmoking and nonalcoholic women on no medication, although chronic inflammation such as periodontitis may cause hypertension through a more direct mechanism.

Abstract
OBJECTIVE The link between periodontal disease and atherosclerosis has not yet been clarified, though systemic inflammation seems to be the common soil for both conditions. Inflammation influences also hemodynamic forces, that act as local risk factors for carotid plaques. It is not known if the link between periodontitis and carotid atherosclerosis is mediated, at least in part, by physical forces. Therefore, aim of the present study was to evaluate the association between carotid shear stress force and periodontal disease. METHODS Thirty-three subjects underwent complete cardiovascular screening, carotid hemodynamic evaluation and dental inspection. Presence of classical risk factors for atherosclerosis, common carotid peak and mean wall shear stress values and periodontal indices of disease (plaque index, gingival index and pocket deep) have been evaluated. RESULTS Worse periodontal health was associated to the presence of carotid atherosclerosis. Patients with carotid plaques (n=19) had higher periodontal indices compared with subjects without plaques (n=14) (gingival index: 1.40 ± 0.71 vs. 0.69 ± 0.64, p=0.006). These relations were independent of the presence of cardiovascular risk factors in multiple logistic regression analysis. In the 66 examined common carotids, wall shear stress was inversely related to all periodontal indices (r=0.54, p<0.00001 for peak wall shear stress and gingival index). These relations remained significant also in multiple regression analysis, after correction for cardiovascular risk factors, gender and age. CONCLUSIONS The present study identifies for the first time a link between periodontal indices and wall shear stress, suggesting that an alteration of hemodynamic profile might contribute to atherosclerosis in subjects with periodontal disease.

Abstract
We aimed to evaluate oral hygiene in patients with Parkinson's disease (PD). The incidence of periodontal disease and numbers of caries and remaining teeth were checked in 89 consecutive 60 to 79-year-old patients with PD and compared with two other patient groups: 68 patients with mild neurological disease, and 60 with acute ischemic stroke. Patients with PD had fewer remaining teeth, more caries and a higher incidence of deep periodontal pockets. The frequency of patients with PD with untreated caries was high at Hoehn and Yahr stage II and above, and frequency tended to increase in patients who had low compared to high mini-mental state examination scores. Careful attention should be paid to the oral hygiene of patients with PD, even in the early stages of the disease.

Abstract
Several cohort studies reported a relation of cardiovascular events and periodontal disease. In particular, Porphyromonas gingivalis is associated with the development of atherosclerotic plaques. We verified in a longitudinal study whether inflammation biomarkers, endothelial adhesion molecules, leukocyte activation markers, and intima-media thickness could be beneficially modified by periodontal treatment alone. Thirty-five otherwise healthy individuals affected by mild to moderate parodontopathy were enrolled in the study. Echo-Doppler cardiography of the carotid artery, fluorescence-activated cell sorting analyses on lymphocytes and monocytes, and plasma inflammatory indices were evaluated at baseline and at multiple time points after the periodontal treatment. Results showed that inflammation biomarkers were abnormally increased at baseline. Periodontal treatment resulted in a significant reduction of the total oral bacterial load that was associated with a significant amelioration of inflammation biomarkers and of adhesion and activation proteins. Notably, intima-media thickness was significantly diminished after treatment. Inflammatory alterations associated with the genesis of atherosclerotic plaques are detected in otherwise healthy individuals affected by parodontopathy and are positively influenced by periodontal treatment. Reduction of oral bacterial load results in a modification of an anatomical parameter directly responsible for atherosclerosis. These results shed light on the pathogenesis of atherosclerosis and could have practical implications for public health.

Abstract
Advice on modifiable risk and lifestyle factors for stroke prevention should be an established component of medical consultation. It is most important to explain that alterations to the lifestyle can be highly efficient with respect to the individual risk profile. The following review describes the importance of lifestyle factors such as nutrition, smoking, alcohol consumption, psychiatric condition, sport, dental hygiene and sleep disturbances for the risk of stroke using current data. It provides evidence that lifestyle modifications are highly effective with respect to stroke prevention. Corresponding recommendations and preventive strategies are presented.

Abstract
An association between atherosclerosis and Porphyromonas gingivalis (P. gingivalis), a major periodontopathogen, has been shown. However, the question of whether this relationship is causal or coincidental still exist. Many individuals with evidence of atherosclerosis demonstrate seropositivity to this pathogen. Both in vitro studies and in animal models document that P. gingivalis can accelerate atheroma deposition. Recently, evidence from diverse sources has suggested P. gingivalis can activate host innate immune responses associated with atherosclerosis. These studies confirm that the inflammatory response to P. gingivalis could exacerbate vascular inflammation via secreted cytokines and/or chemokines that ultimately modulate early atherogenesis that spontaneously develop atherosclerosis. Meanwhile, the cytokine and chemokines interact in the progression of atherosclerosis. Moreover, the reaction of endothelial cells in response to P. gingivalis and its various virulence factors are diverse, the expression of chemokine differ through different signal transduction pathways accordingly. Results from these studies reinforce the connection between P. gingivalis and atherosclerosis. Given the role of P. gingivalis in the initiation and progression of atherosclerosis, attaching importance to periodontal disease may offer new therapeutic options for the management of patients with atherosclerosis.

Abstract
BACKGROUND Periodontal disease (PD) has been recognized as a risk factor for systemic diseases, but its involvement in the pathogenesis of coronary artery disease (CAD) remains debated. OBJECTIVES We sought to evaluate the potential relations between severity of the PD, inflammatory response and angiographic lesions extent in patients with stable CAD. DESIGN A total of 131 subjects referred to our centre for coronary angiography were evaluated for presence and extension of CAD, then divided into two groups, one with presence of lesions (cases, n = 85) and other one with absence of lesions (controls, n = 46). Mean periodontal pocket depth (PPkD), high sensitivity C reactive protein (hs-CRP), serum amyloid A protein (SAA) and fibrinogen levels were measured in all patients. RESULTS Cases and controls did not differ according to their baseline characteristics and prevalence of traditional cardiovascular risk factors. PPkD was greater in patients with CAD than in controls (2.24 +/- 1.28 mm vs 1.50 +/- 0.93 mm, P < 0.001 by Student's t-test). Systemic inflammatory response was more pronounced in cases than in controls, with higher values of hs-CRP, SAA and fibrinogen. Furthermore, PPkD values correlated with hs-CRP (r = 0.80, P < 0.001), SAA (r = 0.71, P < 0.001), fibrinogen levels (r = 0.72, P < 0.001) and the American College of Cardiology/American Heart Association angiographic score (r = 0.68, P < 0.001) in cases. Multivariate analysis indicated a persistent independent correlation between PPkD and angiographic score after adjustment for inflammatory markers levels. CONCLUSION In the present study, PD lesions predicted presence of CAD stenosis in patients with cardiovascular risk factors. PD severity was correlated to angiographic extent of coronary lesions, independent of systemic inflammatory status. Those results suggest that these patients might benefit from an intensive periodontal therapy to prevent CAD progression.

Abstract
BACKGROUND AND PURPOSE In animal models of acute ischemic stroke (AIS), the free radical-trapping agent NXY-059 showed promise as a neuroprotectant. SAINT I and II were randomized, placebo-controlled, double-blind trials to investigate the efficacy of NXY-059 in patients with AIS. METHODS Patients with AIS received an infusion of intravenous NXY-059 or placebo within 6 hours from the onset of stroke symptoms. A pooled individual patient analysis was prespecified to assess the overall efficacy and to examine subgroups. The primary end point was the distribution of disability scores measured on the modified Rankin scale (mRS) at 90 days. Neurologic and activities of daily living scores were investigated as secondary end points. We also evaluated whether treatment with NXY-059 would reduce alteplase-related intracranial hemorrhages. Finally, we evaluated possible predictors of good or poor outcome. RESULTS An intent-to-treat efficacy analysis was based on 5028 patients. Baseline parameters and prognostic factors were well balanced between treatment groups. The distribution of scores on the mRS was not different in the group treated with NXY-059 (n=2438) compared with the placebo group (n=2456): odds ratio for limiting disability=1.02; 95% CI, 0.92 to 1.13 (P=0.682, Cochran-Mantel-Haenszel test). Comparisons at each level of the mRS confirmed an absence of benefit. There was no evidence of efficacy in prespecified subgroups or from the secondary outcome analyses. Mortality was equal in the 2 groups (16.7% vs 16.5%), and adverse event rates were similar. Among patients treated with alteplase, there was no decrease in rates of symptomatic or asymptomatic hemorrhage associated with NXY-059 treatment versus placebo. Subgroup analyses identified National Institutes of Health Stroke Scale score, age, markers of inflammation, blood glucose, and right-sided infarct as predictors of poor outcome. CONCLUSIONS NXY-059 is ineffective for treatment of AIS within 6 hours of symptom onset. This is also true for subgroups and the prevention of alteplase-associated hemorrhage.

Abstract
It is the position of the American Dietetic Association that nutrition is an integral component of oral health. The American Dietetic Association supports the integration of oral health with nutrition services, education, and research. Collaboration between dietetics and dental professionals is recommended for oral health promotion and disease prevention and intervention. Scientific and epidemiological data suggest a lifelong synergy between nutrition and the integrity of the oral cavity in health and disease. Oral health and nutrition have a synergistic bidirectional relationship. Oral infectious diseases, as well as acute, chronic, and terminal systemic diseases with oral manifestations, impact the functional ability to eat as well as diet and nutrition status. Likewise, nutrition and diet may affect the development and integrity of the oral cavity as well as the progression of oral diseases. As we advance in our discoveries of the links between oral and nutrition health, practitioners of both disciplines must learn to provide screening, baseline education, and referral to each other as part of comprehensive client/patient care. Dietetics practice requires registered dietitians to provide medical nutrition therapy that incorporates a person's total health needs, including oral health. Inclusion of both didactic and clinical practice concepts that illustrate the role of nutrition in oral health is essential in both dental and dietetic education programs. Collaborative endeavors between dietetics and dentistry in research, education, and delineation of health provider practice roles are needed to ensure comprehensive health care. The multifaceted interactions between diet, nutrition, and oral health in practice, education, and research in both dietetics and dentistry merit continued, detailed delineation.
