Abstract
Worldwide, more people die of the complications of atherosclerosis than of any other cause. It is not surprising, therefore, that enormous resources have been devoted to studying the pathogenesis of this condition. This article attempts to summarize present knowledge on the events that take place within the arterial wall during atherogenesis. Classical risk factors are not dealt with as they are the subjects of other parts of this book. First, we deal with the role of endothelial dysfunction and infection in initiating the atherosclerotic lesion. Then we describe the development of the lesion itself, with particular emphasis on the cell types involved and the interactions between them. The next section of the chapter deals with the events leading to thrombotic occlusion of the atherosclerotic vessel, the cause of heart attack and stroke. Finally, we describe the advantages--and limitations--of current animal models as they contribute to our understanding of atherosclerosis and its complications.

Abstract
OBJECTIVE Periodontal disease may contribute to the increased mortality associated with diabetes. RESEARCH DESIGN AND METHODS In a prospective longitudinal study of 628 subjects aged > or =35 years, we examined the effect of periodontal disease on overall and cardiovascular disease mortality in Pima Indians with type 2 diabetes. Periodontal abnormality was classified as no or mild, moderate, and severe, based on panoramic radiographs and clinical dental examinations. RESULTS During a median follow-up of 11 years (range 0.3-16), 204 subjects died. The age- and sex-adjusted death rates for all natural causes expressed as the number of deaths per 1,000 person-years of follow-up were 3.7 (95% CI 0.7-6.6) for no or mild periodontal disease, 19.6 (10.7-28.5) for moderate periodontal disease, and 28.4 (22.3-34.6) for severe periodontal disease. Periodontal disease predicted deaths from ischemic heart disease (IHD) (P trend = 0.04) and diabetic nephropathy (P trend < 0.01). Death rates from other causes were not associated with periodontal disease. After adjustment for age, sex, duration of diabetes, HbA1c, macroalbuminuria, BMI, serum cholesterol concentration, hypertension, electrocardiographic abnormalities, and current smoking in a proportional hazards model, subjects with severe periodontal disease had 3.2 times the risk (95% CI 1.1-9.3) of cardiorenal mortality (IHD and diabetic nephropathy combined) compared with the reference group (no or mild periodontal disease and moderate periodontal disease combined). CONCLUSIONS Periodontal disease is a strong predictor of mortality from IHD and diabetic nephropathy in Pima Indians with type 2 diabetes. The effect of periodontal disease is in addition to the effects of traditional risk factors for these diseases.

Abstract
OBJECTIVES This paper evaluates the relation of tooth loss to incidence of coronary heart disease in two large cohort studies. METHODS Participants included 41,407 men and 58,974 women free of any cardiovascular diseases at baseline. We recorded 1,654 incident coronary heart disease events (562 fatal events) among men during 12 years of follow-up and 544 events (158 fatal events) among women during 6 years of follow-up. RESULTS After controlling for important cardiovascular risk factors, compared to men with 25-32 teeth at baseline, men with 0-10 teeth had a significantly higher risk of coronary heart disease (relative risk [RR]= 1.36; 95 percent confidence interval [CI]=1.11, 1.67). The relative risk increased to 1.79 (95% CI=1.34, 2.40) when limited to fatal events. Women with 0-10 teeth were also at increased risk of coronary heart disease compared to women with 25-32 teeth (RR=1.64; 95% CI=1.31, 2.05). The association was similar for fatal events (RR= 1.65; 95% CI=1.11, 2.46). The association between number of teeth and incidence of coronary heart disease was similar between men with and without a history of periodontal disease, and there was no significant association between tooth loss during follow-up and coronary heart disease. CONCLUSIONS This study showed a significant association between number of teeth at baseline and risk of coronary heart disease and the mechanisms to explain this association should be further clarified.

Abstract
BACKGROUND There is increasing evidence that chronic infections, such as periodontal diseases, could play a role in the initiation and development of coronary artery disease (CAD). The present study was intended to test for a possible association between presence and severity of periodontitis and coronary artery disease in a Belgian population. METHODS A total of 108 CAD patients (mean age 59.2 +/- 11 years) and 62 presumably healthy controls (mean age 57.7 +/- 9 years) were enrolled in the study. Probing depth, periodontal pocket bleeding index (PPBI), plaque index, furcation involvements, and tooth mobility were evaluated to compare periodontal health in both groups. The subjects were also ranked according to a novel index of periodontitis severity, the periodontal index for risk of infectiousness (PIRI), aimed at quantifying the risk of release of proinflammatory mediators from the periodontal sites. RESULTS Periodontitis was significantly more frequent in CAD patients than in controls (CAD patients: 91%; controls: 66%). The mean number of pockets was 18 +/- 17.1 in cardiac patients versus 7.6 +/- 12.7 in controls (P < 0.0001), despite the fact that the mean number of missing teeth was significantly greater in cases than in controls (14 +/- 7.1 versus 9 +/- 5.2; P < 0.0001). Furthermore, proportions of mobile teeth, bleeding sites, periodontal pockets, and involved furcations were significantly higher in CAD patients than in controls. In addition, the extent of the periodontal disease present was also greater in cases than in controls. A logistic model, adjusted for known cardiovascular risk factors, showed a strong association between CAD and periodontitis (odds ratio [OR] = 6.5). Moreover, there was a significant dose-response relationship between increasing scores of the periodontal risk of infectiousness and the presence of CAD (adjusted OR = 1.3 per PIRI unit). CONCLUSION In the present study, periodontitis was revealed to be a significant risk factor for CAD after adjusting for other confounding factors, with the level of association increasing with the individual extent of the periodontal lesions.

Abstract
BACKGROUND Recent epidemiological data suggested that there is a relationship between periodontal health and atherosclerotic coronary heart disease. Although hypothetical models were proposed, the exact mechanism of this association has not been clarified. The aim of this study is to investigate whether there is an endothelial dysfunction in patients with chronic periodontitis and, if present, whether recovery is possible with therapy. METHODS The study groups consisted of 28 patients (mean age: 45.5 +/- 8.6 years) with chronic periodontitis and without any atherosclerotic vascular disease, and 26 healthy controls (mean age: 43.7 +/- 6.8 years). Cardiovascular risk factors were investigated in both groups. Brachial artery responses to reactive hyperemia (endothelium-dependent dilatation [EDD]) and sublingual nitroglycerin (endothelium-independent dilatation [EID]) were measured using high-resolution vascular ultrasound in both groups. Measurements were taken before and after initial periodontal therapy in the periodontal patients. RESULTS There was no significant difference between the groups with regard to cardiovascular risk factors. In the baseline measurements, EDD and EID were significantly impaired in patients with chronic periodontitis when compared with the controls (8.4% +/- 4.0% versus 19.4% +/- 8.1%, P<0.0001; 13.3% +/- 6.3% versus 29.5% +/- 10.0%, P<0.0001 for EDD and EID, respectively). After non-surgical periodontal therapy, EDD and EID improved significantly (from 8.4% +/- 4.0% to 17.7% +/- 5.7%, P<0.0001; and from 13.3% +/- 6.3% to 24.9% +/- 7.3%, P<0.0001 for FMD and EID, respectively). The EDD and EID changes in the controls were insignificant. CONCLUSION This study showed that endothelial functions were impaired in patients with chronic periodontitis and that they improve following initial periodontal therapy.

Abstract
During the last two decades, there has been an increasing interest in the impact of oral health on atherosclerosis and subsequent cardiovascular disease (CVD). The advent of the inflammation paradigm in coronary pathogenesis stimulated research in chronic infections caused by a variety of micro-organisms-such as Chlamydia pneumoniae, Helicobacter pylori, and cytomegalovirus-as well as dental pathogens, since these chronic infections are thought to be involved in the etiopathogenesis of CVD by releasing cytokines and other pro-inflammatory mediators (e.g., C-reactive protein [CRP], tumor necrosis factor [TNF-alpha]) that may initiate a cascade of biochemical reactions and cause endothelial damage and facilitate cholesterol plaque attachment. Yet, due to the multi-factorial nature of dental infection and CVD, confirming a causal association is difficult, and the published results are conflicting. The main deficit in the majority of these studies has been the inadequate control of numerous confounding factors, leading to an overestimation and the imprecise measurement of the predictor or overadjustment of the confounding variables, resulting in underestimation of the risks. A meta-analysis of prospective and retrospective follow-up studies has shown that periodontal disease may increase the risk of CVD by approximately 20% (95% confidence interval [CI], 1.08-1.32). Similarly, the reported risk ratio between periodontal disease and stroke is even stronger, varying from 2.85 (CI 1.78-4.56) to 1.74 (CI 1.08-2.81). The association between peripheral vascular disease and oral health parameters has been explored in only two studies, and the resultant relative risks among individuals with periodontitis were 1.41 (CI 1.12-1.77) and 2.27 (CI 1.32-3.90), respectively. Overall, it appears that periodontal disease may indeed contribute to the pathogenesis of cardiovascular disease, although the statistical effect size is small.

Abstract
BACKGROUND This meta-analysis was conducted to examine the relationship between periodontal diseases and coronary heart diseases (CHD) and cerebrovascular diseases (CVD) in observational studies. METHODS This study was based on seven cohort studies and four studies of other designs that met prestated inclusion criteria. Information on study design, year of publication, study location, sample size, study population, participant characteristics, measurement of risk factors, exposure and outcome measures, matching, controlling for confounders, and risk estimates was abstracted independently by two investigators using a standard protocol. RESULTS Subjects with periodontitis had an overall adjusted risk of CHD that was 1.15 times (95% confidence interval [CI]: 1.06 to 1.25; P = 0.001) the risk for healthy subjects. There was no heterogeneity among the studies in the overall relative risk estimate (P = 0.472). As compared to healthy subjects, those with periodontitis had an overall adjusted relative risk of CVD of 1.13 (95% CI: 1.01 to 1.27; P = 0.032). CONCLUSIONS Findings indicated that periodontal infection increases the risk of CHD and CVD. However, this meta-analysis provided no evidence for the existence of strong associations between periodontitis and CHD and CVD. Larger and better-controlled studies involving socially homogeneous populations and measuring specific periodontal pathogens are required to identify a definite association between periodontal disease and the risk of coronary heart disease and cerebrovascular disease.

Abstract
OBJECTIVES The aim of the present study was to follow-up the condition of the teeth over a sufficiently long period. METHODS Dental examinations were a part of a multidisciplinary 10-year cohort study on the elderly. These examinations were made in 1990 (n = 226), 1995 (n = 90) and 2000 (n = 65) for the entire population born in 1910 and living in Jyväskylä, Finland. The subjects were divided into two categories, dentate (one tooth or more) and edentulous. RESULTS The results showed that men had more intact teeth and lower DMF scores than women, but the differences diminished during the follow-up period. The number of remaining and filled teeth of those women who took part in all three phases of the present study was higher than that of those who died during the follow-up. In men the DMF scores showed the opposite trend. The most significant deterioration during the 10-year follow-up was found in the number of teeth and DMF scores in men and in the number of remaining and filled teeth in women. CONCLUSION Among men, in particular, significant changes in oral health status could be seen even between 80 and 90 years of age. Hence, regardless of advanced age, a subject should be motivated by the oral health care team to seek regular dental treatment.

Abstract
OBJECTIVES The objective of this study was to determine if an association existed between periodontal disease and various systemic medical conditions and tobacco use. MATERIAL AND METHODS The study design was a case-controlled, retrospective chart review. Patient charts (n=2006) were selected from more than 13,000 active patients attending the University of Minnesota dental clinics. These charts were examined to determine patient's self-reported systemic condition and smoking history. In addition, the number of missing teeth and bone loss were recorded. Two examiners collected the data. One examiner abstracted patient's medical history from the standard clinic medical questionnaire. The second examiner assessed the radiographs and dental charts to determine bone loss and number of missing teeth. Each examiner was blind to the findings of the other. RESULTS After adjusting for age, sex, diabetes and smoking (yes/no) status, seven conditions were significantly (p=0.0003-0.04) related to bone loss or number of missing teeth (vascular disease, heart surgery, vascular surgery, heart attack, thyroid problems, arthritis, stomach ulcers). From these conditions, thyroid problems and arthritis had a negative association with bone loss. CONCLUSIONS These findings support the results from previous investigators that a number of systemic conditions and smoking are closely associated with missing teeth or bone loss.

Abstract
OBJECTIVES To describe life-style correlates of tooth loss in a representative rural American population. METHODS Information on tooth loss as well as past medical history and life-style factors was obtained in a well-defined cohort of 2,764 persons 53-96 years of age in Beaver Dam, WI (1998-2000). RESULTS There were 1,992 (68.2%) persons missing some and 447 (15.3%) missing all of their teeth. In univariable analyses, age, cigarette smoking, heavy drinking, education, multivitamin use, and diabetes status were associated with tooth loss. Tooth loss was associated with poorer self-rated health and with difficulty eating solid food and inability to enjoy some food. In multivariable models age, education, smoking, heavy drinking, and diabetes were significantly associated with tooth loss. CONCLUSIONS Tooth loss is common in older persons and is associated with many risk factors including education, smoking, and heavy drinking. It is possible that modifying these may influence risk of tooth loss.

Abstract
BACKGROUND Studies relating periodontal disease to coronary heart disease (CHD) have provided equivocal results using tooth loss and/or clinical signs of periodontal disease as measures of periodontal exposure. METHODS The purpose of this cross-sectional study was to evaluate the relationship of tooth loss and periodontitis to prevalent CHD at the Atherosclerosis Risk in Communities (ARIC) visit 4 using both tooth loss and clinical signs of disease in a population-based sample of 8,363 men and women aged 52 to 75 years from four U.S. communities. Each subject participated in a complete periodontal examination, assessment of missing teeth, assessment of prevalent CHD, and a number of laboratory tests and questionnaires. High attachment loss was defined as > or = 10% of sites with attachment loss > 3 mm and high tooth loss was defined as fewer than 17 remaining teeth. RESULTS Individuals with both high attachment loss and high tooth loss (odds ratio [OR] 1.5, 95% confidence interval [CI] 1.1 to 2.0) and edentulous individuals (OR 1.8, CI 1.4 to 2.4) had elevated odds of prevalent CHD compared to individuals with low attachment loss and low tooth loss, while controlling for a number of traditional risk factors for CHD. CONCLUSIONS These results suggest that tooth loss and periodontal disease are associated with prevalent CHD, but only when both are present. The weaker relationships between periodontal disease and CHD that have been found among older adults may be due to older adults having fewer teeth. Future longitudinal studies should be designed to ascertain the cause of tooth loss during follow-up.

Abstract
BACKGROUND Recent studies have suggested a relationship between periodontitis and cardiovascular disease (CVD). This study investigated the relationship between periodontitis and electrocardiographic (ECG) abnormalities, which are known predictors of CVD. METHODS We examined the periodontal status of 1,111 residents of Hisayama Town, Fukuoka, Japan. Nine hundred fifty-seven (957) subjects (374 males, 583 females) with > or = 10 teeth and without a medical history of CVD were included in the analysis. Probing depth (PD) and clinical attachment level (CAL) were measured on two randomly selected quadrants, one maxillary and one mandibular. A 12-lead ECG was recorded using a standard electrocardiograph. ECG abnormalities included left ventricular hypertrophy (Minnesota code 3-1) and ST depression (4-1, 2, 3). The relation of periodontal condition and ECG abnormalities was assessed with logistic regression analysis. RESULTS Univariate analysis revealed that mean probing depth, mean attachment loss, number of teeth, and plaque index were significantly associated with ECG abnormalities, as well as with known risk factors of CVD. In multivariate analysis, the subjects with deep pockets (mean probing depth > or = 2 mm) had an increased risk for ECG abnormalities (odds ratio [OR] = 1.6; 95% confidence interval [CI] = 1.01 to 2.50) compared to the subjects with mean PD < 2 mm. Subjects with severe attachment loss (mean CAL > or = 2.5 mm) had also significant risk for ECG abnormalities (OR = 1.7; 95% CI = 1.07 to 2.67) compared to those whose mean CAL was < 2.5 mm. CONCLUSION This study clearly shows the relationship between periodontitis and ECG abnormalities, which are important predictors of CVD.

Abstract
Tooth loss has been associated with an increased risk of vascular diseases such as coronary heart disease and cerebrovascular disease. Little is known whether hypertension is an important factor linking 2 phenomena in postmenopausal women. We compared an incidence of hypertension and traditional risk factors for vascular diseases between 2 age-matched groups: 67 postmenopausal women with missing teeth and 31 without missing teeth. In addition to blood pressure, serum concentration of total cholesterol, high- and low-density lipoprotein cholesterol and triglycerides, plasma angiotensin-converting enzyme activity, plasma angiotensin II concentration, plasma renin activity, and resting heart rate were measured as traditional risk factors for vascular diseases. Subjects without missing teeth had significantly lower diastolic blood pressure than did subjects with missing teeth (P=0.021). The former tended to have lower systolic blood pressure than did the latter (P=0.058). There were no significant differences in other variables between subjects with and without missing teeth. The odds ratio of having hypertension in subjects with missing teeth was 3.59 (95% confidence interval, 1.10 to 11.7) after adjustment of obesity, hypercholesterolemia, and hypertriglyceridemia. Our results suggest that hypertension may be an important factor linking tooth loss and an increased risk of vascular diseases in postmenopausal women.

Abstract
OBJECTIVES To assess the relationship between poor oral health and coronary heart disease (CHD) and systemic inflammatory and haemostatic factors in an Italian population. MATERIAL AND METHODS The study population consisted of 63 males aged 40-65 years with proven CHD and 50 controls matched for age, geographic area, and socioeconomic status. A detailed description of their oral status was given using four different dental indices (total dental index (TDI), panoramic tomography score, clinical periodontal sum score (CPSS), and clinical and radiographic sum score (CRSS)). Blood samples were taken for measurement of the following CHD risk factors: serum total cholesterol, triglycerides, high-density lipoprotein (HDL) cholesterol, low-density lipoprotein (LDL) cholesterol, and glucose; a series of systemic markers of inflammation (C-reactive protein, leucocytes, fibrinogen, homocysteine) and a series of haemostatic factors (von Willebrand factor, fibrin D-dimer, prothrombinic fragment F1.2, plasminogen activator inhibitor type I (PAI-1), and serum antibodies) against oxidized LDL (anti-Ox-LDL). RESULTS Multiple logistic regression adjusted for all risk factors for CHD showed statistically significant relationships (p<0.01) between all dental indices and CHD. Significant relationships (p always <0.01) were found between CPSS and CRSS and leucocyte count. Significant relationships (p always <0.05) were also found between TDI and the von Willebrand factor, and between CPSS and the von Willebrand factor, anti-Ox-LDL, and PAI-1. CONCLUSIONS The present study suggests an association between poor oral status and CHD, and provides evidence that inflammatory and haemostatic factors could play an important role in this association.

Abstract
BACKGROUND An association between periodontitis and cardiovascular diseases has been suggested. AIMS To study whether a combination of clinical variables in a functional risk diagram enhanced the ability to differentiate between subjects with or without an immediate history of acute myocardial infarction (AMI). MATERIAL AND METHODS A functional periodontal pentagon risk diagram (PPRD) with five periodontal risk vectors was created. The surface of individual PPRDs was calculated using data from 88 subjects with recent AMI and 80 matched control subjects with no history of AMI. RESULTS Age, gender, number of remaining teeth (mean value: 21.1 versus 21.6 teeth), smoking status, and pocket probing depth (PPD) distribution did not differ by group. Gingival recession was greater in control subjects (mean difference: 5.7, SD: +/- 1.9, p<0.01, 95% CI: 1.8-9.6). Bone loss > or = 4.0 mm was at all levels studied was significantly greater in subjects with AMI and bone loss > or = 50% (> or = 4 mm) was the best individual predictor of AMI (beta = 2.99, p < 0.000, 95% CI: 7.5-53.4). Only PPRD scores were associated with AMI status when factors not included in the PPRD were studied (beta = 22.1, SE: 5.9, p < 0.0001, 95% CI: 10.3-33.7). The best association between AMI status and study variables was the combination of > or = 4 mm of bone loss > or = 50%, proportion of bleeding on probing (%BOP), %PPDs > or = 6 mm, and tooth loss (Nagelkirke r2 = 0.46). CONCLUSIONS The combination of five periodontal parameters in a PPRD added predictive value, suggesting that comprehensive data should be used in studies of associations between periodontitis and heart diseases. Radiographic evidence of bone loss was the best individual parameter.

Abstract
BACKGROUND Periodontitis has been linked to coronary heart disease (CHD) risk, possibly through providing a systemic inflammatory burden. Few studies have evaluated periodontitis and subclinical measures of atherosclerosis. Coronary artery calcification (CAC) is an emerging marker for atherosclerosis, and past studies suggest that it predicts incident CHD in asymptomatic populations. METHODS In 1996-1998, dental examinations were performed on 6,931 participants in the Atherosclerosis Risk in Communities (ARIC) cohort. Extent of periodontitis was measured by the percent of sites with attachment level (AL) > or = 3 mm. In 1999-2000, CAC was measured by cardiac gated mechanical or helical computed tomography in 269 dental examinees and edentulous subjects from the Minnesota and North Carolina field centers of ARIC who were free of clinically recognized CHD. A traditional Agatston score for CAC was calculated. RESULTS Compared to subjects with no or mild periodontitis (<10% of sites with AL > or = 3 mm), subjects with moderate or severe periodontitis (> or = 10% of sites with AL > or = 3 mm) were more likely to have CAC > or = 100, but this difference was not statistically significant (odds ratio [OR]: 1.78; 95% confidence interval [CI]: 0.65 to 4.86). This association was partially but not completely attenuated when adjusted for demographic factors and traditional CHD risk factors (OR: 1.51; 95% CI: 0.54 to 4.23). CONCLUSIONS These results suggest that periodontitis is not strongly associated with CAC. This study offers some reference for the magnitude of the association between CAC and periodontitis and information regarding the minimal power necessary for future studies.

Abstract
We investigated the relationship between periodontitis and mortality in home-dwelling individuals aged (75+ years), considering potential confounders including C-reactive protein levels. This study involved 364 individuals, originally part of the Helsinki Ageing Study cohort, who underwent medical and dental examinations in 1990 and were followed for five years. After five years, 52 of the 175 dentate subjects had died. Using univariate analysis, the association between baseline periodontitis and mortality was of borderline significance. After controlling for the common risk factors, periodontitis more than doubled the risk of cardiovascular disease-related mortality (HR 2.28, CI 1.03-5.05). The increase in total mortality was, however, not statistically significant (HR 1.43, CI 0.81-2.50). Subjects who were edentulous had higher mortality than those who were dentate without periodontitis, but the difference was not statistically significant. A baseline CRP level above 3 mg/l was associated with high mortality; but this effect was significant only among individuals with periodontitis. These results suggest that periodontitis influences the pathogenesis and outcome of cardiovascular disease, especially in individuals who also have evidence of a systemic inflammatory reaction.

Abstract
BACKGROUND The acute-phase response involves molecules including tumor necrosis factor-alpha (TNF-alpha), interleukin-6 (IL-6), and C-reactive protein (CRP). This study aimed to determine whether subgingival scaling resulted in rapid changes in plasma concentrations of these molecules. METHODS Twenty-three non-smoking adults with chronic periodontitis received subgingival scaling for 60 minutes. Venous blood samples were taken at 0, 15, 30, 60, and 120 minutes. TNF-alpha and IL-6 were assayed from all samples and CRP from the baseline and final samples. Lipopolysaccharide (LPS) was assayed at 0, 15, and 30 minutes using limulus lysate assay (LAL) and EndoCAb Ig assays. RESULTS LPS assays were suggestive of a transient low-grade bacteremia, but changes in LPS approaching significance (P=0.061) were seen with LAL only. There was a significant increase in circulating TNF-alpha (P=0.0387) and IL-6 (P<0.0001), and the degree of change in TNF-alpha was correlated with the severity of periodontal breakdown (P=0.001). There was also a significant correlation between levels of IL-6 and TNF-alpha (P<0.001). CONCLUSIONS Chronic periodontitis patients undergoing an episode of subgingival scaling show a significant elevation in circulating TNF-alpha and IL-6. This may account for anecdotal reports of pyrexia following treatment and may be significant in terms of the relationship between periodontal disease, bacteremia, and cardiovascular disease.

Abstract
BACKGROUND Oral infections have been postulated to produce cytokines that may contribute to the pathogenesis of coronary heart disease (CHD). We hypothesized that by estimating the combined production of inflammatory mediators attributable to several oral pathologies, we might be able to explain CHD with better precision. METHODS AND RESULTS A total of 256 consecutive Finnish cardiac patients from Kuopio University Hospital with angiographically confirmed CHD and 250 age-, gender-, and residence-matched noncardiac patients (controls) were recruited. All dental factors expected to generate inflammatory mediators, including pericoronitis, dental caries, dentate status, root remnants, and gingivitis, were examined, and an asymptotic dental score (ADS) was developed by logistic regression analyses with an appropriate weighting scheme according to the likelihood ratio. We validated the explanatory ability of ADS by comparing it to that of the Total Dental Index and examining whether the ADS was associated with known predictors of CHD. A model that included ADS, C-reactive protein, HDL, and fibrinogen offered an explanatory ability that equaled or exceeded that of the Framingham heart score (C statistic=0.82 versus 0.80). When ADS was removed from this model, the C-statistic decreased to 0.77, which indicates that the ADS was a significant contributor to the explanatory ability of a logistic model. CONCLUSIONS ADS may be useful as a prescreening tool to promote proactive cardiac evaluation among individuals without overt symptoms of CHD. However, additional prospective study is needed to validate the use of an oral health score as a predictor of incident CHD.

Abstract
BACKGROUND Edentulism may affect dietary intake in older adults, but the relation between edentulism and nutritional status is not completely understood. OBJECTIVE The present study examined whether edentulism is associated with nutritional status and whether there is an interaction between race and edentulism on nutritional status among well-functioning, community-dwelling elderly. DESIGN The study cohort included 3075 elderly aged 70-79 y (52% women, 42% black) in the Health, Aging, and Body Composition Study. Dietary intake, anthropometric variables, weight change, and serum albumin and lipid concentrations were compared between edentate and dentate participants by the use of multiple linear and logistic regressions. RESULTS Edentulism was not associated with total energy or food intake but was associated with the food groups consumed, particularly fat, micronutrients, and hard-to-chew foods. Edentulism was more strongly linked to dietary intake in whites than in blacks. Unlike black edentate elderly, white edentate elderly consumed significantly lower energy-adjusted amounts of vitamin A and beta-carotene, higher amounts of energy-adjusted total and saturated fat and cholesterol, and higher percentages of energy from fat than did white dentate elderly. Anthropometry and biochemical indexes were not significantly different by edentulism status in both races. Edentulism was associated with weight gains of >5% in 1 y in both races. CONCLUSIONS Edentulism was associated with differences in the nutritional status of well-functioning, community-dwelling elderly, more so in whites than blacks. Edentate elders may benefit from dental, medical, and nutrition interventions targeted to addressing these findings.

Abstract
There is recent interest in recovery of periodontopathogenic bacteria from arterial and bronchial tissues to identify a link between periodontal and cardiovascular or pulmonary diseases. This interest could provide a useful clinical correlation exercise for gross anatomy. Our objective was to perform a feasibility study to determine whether these bacteria could be recovered from two sites within eight (4 dentate, 4 edentulous) human embalmed cadavers from an anatomical dissection laboratory. Bacterial samples were collected from the right coronary artery and the right superior secondary bronchus and assayed for the presence and concentrations of the DNA of A. actinomycetemcomitans, E. corrodens, C. rectus, P. intermedia, P. gingivalis, B. forsythus, T. denticola, and F. nucleatum. Frequencies were compared using a Kruskal-Wallis H-test. Correlations between the presence of teeth, bacterial species, and site were determined by a Spearman's rho correlation test. A. actinomycetemcomitans and B. forsythus frequencies were different between the sites in edentulous subjects (P <0.05); the frequency of B. forsythus was different in dentate and edentulous subjects at the bronchus site (P <0.05). Numerous significant correlations were identified between strains of bacteria, site, and presence of teeth. Thus, it is possible for the DNA of periodontopathogenic bacteria to be recovered from human embalmed cadavers. Collection and identification of these bacteria from these cadavers could be a useful clinical correlation exercise for dental students in a gross anatomy class.

Abstract
The purpose of this study was to investigate the association between periodontal conditions and electrocardiogram test results that were obtained to screen for coronary heart disease risk factors. The present study included a total of 578 subjects who underwent annual medical check-ups at the Total Health Care Center in Otsu, Shiga Prefecture, Japan. To calculate the odds ratios for the electromyography abnormalities, we performed a logistic regression analysis for the oral examination, electrocardiogram, and blood analysis data. The crude odds ratio was obtained by a logistic regression analysis of age, sex, number of missing teeth, number of filled teeth, simplified oral hygiene index, community periodontal index, and blood analysis factors and results indicated there was a statistically significant correlation with the prevalence of electrocardiogram abnormalities. However, electrocardiogram abnormalities have a strong correlation with demographic factors such as sex and age. Therefore the experimental factors representing oral status were reexamined after the odds ratios were adjusted for age and sex. As a result of this adjustment, the new odds ratios that were determined indicated that there were no correlations between the oral factors and the prevalence of electrocardiogram abnormalities.

Abstract
Several studies have shown that oral health problems impact the quality of life of older adults. However, few data are available to describe the oral health status, barriers to care, and patterns of care for adults and older populations living in rural areas. The purpose of this study was to evaluate the perceived need for treatment of oral health problems by adult residents in a rural county in Iowa. The oral health component was part of a larger longitudinal health study of the residents. The sample was stratified into three groups by residence, that is, farm households, rural non-farm households and town households. The sample was subsequently post-stratified by gender and age group into young elderly, 65-74 years old, and old elderly, 75 years and older. Dentition status varied according to age and was related to the perception of treatment needs. Edentulous persons had fewer perceived treatment needs and utilized a dentist less frequently. Place of residence, education, and marital status were not associated with the subjects' perceived problems with eating and chewing. However, persons with difficulty chewing were more likely to have some missing upper teeth, have a perceived need to have denture work, and have smoked for a number of years. The results suggest that this rural population is retaining more teeth and consequently may need and may seek dental services more often than previous more edentulous cohorts.

Abstract
BACKGROUND Duplex ultrasonography (DS) is a frequently used noninvasive method for assessing carotid artery stenosis. The level of agreement between panoramic radiographs (PMX) findings of radiopacities in the area of C3-C4 and DS results has not been established. AIMS (1) to examine the level of agreement between DS results and PMX signs of carotid calcification and (2) to evaluate the association between periodontitis and DS results. MATERIAL AND METHODS Eighty-three subjects who had received a DS assessment at the University of Washington Medical Center within 36 months volunteered for a periodontal examination, including assessments of probing pocket depth (PPD), attachment level (PAL), evidence of bleeding on probing and bone loss from PMX. Two examiners independently analyzed the radiographs for evidence of carotid calcifications. The distance between the cemento-enamel junction (CEJ) to bone level (BL) CEJ-BL was used to assess alveolar bone loss as a criteria for periodontitis. RESULTS Twenty-nine subjects (34.9%) presented with positive DS readings. The Mantel-Haentszel common odds ratio estimate for a positive DS score and periodontitis (> 30% of teeth with distance CEJ-BL > or = 4.0 mm) was 38.4 (95% CI: 10.6-138.7, p < 0.0001). For nonsmokers only (n = 72) the odds ratio was 43.0 (95% CI: 16.7-1178.0, p < 0.0001). Evidence of bleeding on probing was 16% of sites both in the DS-positive and -negative subjects. Subjects with a positive DS result had significantly more teeth with clinical evidence of attachment loss > or = 5.0 mm (p < 0.001). The odds ratio of having periodontitis (CEJ-BL > or = 4.0 mm at > or = 30% of the teeth) and medical records confirmed diagnosis of either a stroke or an infarct or both was 7.8 (95% CI: 2.6-23.8, p < 0.001). CONCLUSIONS Subjects with positive DS readings of the carotid arteries due to calcified arterial plaque are accurately detected by means of conventional PMX. The likelihood of being DS positive and having radiographic evidence of periodontitis is high. A dose-response relationship between the extent of carotid calcification and severity of periodontitis was demonstrated, supporting the hypothesis of an association between periodontitis and cardiovascular diseases.

Abstract
This study evaluated whether oral disorders were associated with chronic systemic diseases in 532 Canadian adults who are old and very old and living in institutions. A brief oral examination documented tooth retention, caries, and periodontal and gingival health. Medical records provided information about chronic systemic conditions. A history of stroke was associated with a higher experience of caries, a higher ratio of decayed-to-present teeth, and more gingival and periodontal problems. Participants with high blood pressure, osteoporosis, or diabetes were more likely to be edentulous or to have fewer teeth than participants who did not have these conditions. Participants who had arthritis retained more teeth with age. Participants who had more diseases also tended to have poorer gingival or periodontal conditions, fewer teeth, and higher risk of edentulousness. The associations between systemic diseases and more severe oral disorders may be direct or may be mediated by underlying factors such as health behaviors.

Abstract
OBJECTIVE Despite dramatic improvements in tooth retention around the world, a substantial proportion of older adults have lost natural teeth and many wear removable partial and complete dentures. Problems associated with tooth loss and denture wearing remain important in the context of global ageing. The purpose of this paper is to examine the effects of tooth loss and denture wearing on their day-to-day lives from the patient perspective. DESIGN Cross-sectional study. SETTING Greater Boston area, USA. PARTICIPANTS Community-dwelling older men. METHODS Brief examination and survey. MAIN OUTCOME MEASURES Self-reported oral health measures including the single-item self-rating of oral health, the Oral Health Impact Profile (OHIP), the Geriatric Oral Health Assessment Index (GOHAI), Oral-Health-related Quality of Life (OHQOL) and a newly-developed short-form instrument (the DELTA). RESULTS Men with > or = 25 teeth had better self-rated oral health by all measures. The new, brief DELTA differentiates between dentition/denture groupings as well as or better than existing instruments. Over 80% of men with > or = 25 teeth rated their oral health as excellent, very good or good, compared with 70% of men with no teeth (and dentures) and 54% of men with 1-24 teeth. Avoidance of certain foods discriminates well between dentition groups. To a lesser extent, difficulty with relaxation, pain and distress, and avoidance of going out are associated with tooth loss and/or denture wearing.

Abstract
This cross-sectional study was designed to explore a possible association between endodontic disease variables and coronary heart disease (CHD). Dental infections are hypothesized to be linked to atherosclerosis and could be a cause of vascular changes crucial for the development of CHD. Most studies have focused on periodontal disease. To our knowledge, no one has specifically studied endodontic variables as risk factors for the development of CHD. In 1992-93, a representative sample (n = 1056) of women in Göteborg, Sweden, aged between 38 and 84 years, took part in a combined dental and medical survey. The dependent variable was CHD, i.e. subjects with angina pectoris and/or a history of myocardial infarction (n = 106). The independent variables were number of root-filled teeth (RF), number of teeth with periapical radiolucencies (PA), tooth loss (TL), age, life situation, marital status, smoking, alcohol habits, body mass index, waist-hip ratio, serum cholesterol and triglyceride concentrations, hypertension and diabetes. The multivariate logistic regression analysis did not prove the endodontic variables to be predictive of CHD. Only age and tooth loss were significantly associated with CHD, with OR = 1.07 (CI = 1.03-1.12) and OR = 2.70 (CI = 1.49-4.87), respectively. The bivariate logistic regression analysis showed a positive significant association between subjects with RF = 2 and CHD, but for PA the bivariate analysis did not support an association with CHD. This cross-sectional study did not reveal a significant association between endodontically treated teeth and CHD nor between teeth with periapical disease and CHD.

Abstract
BACKGROUND Several studies have reported that impaired dentition status is associated with poor nutritional intake. However, most of these studies are cross-sectional and thus are unable to clarify the temporal sequence. METHODS We assessed the longitudinal relation between tooth loss and changes in consumption of fruits and vegetables and of nutrients important for general health among 31,813 eligible male health professionals. RESULTS Subjects who lost five or more teeth had a significantly smaller reduction in consumption of dietary cholesterol and vitamin B12, greater reduction in consumption of polyunsaturated fat and smaller increase in consumption of dietary fiber and whole fruit than did subjects who had lost no teeth. Men who had lost teeth also were more likely to stop eating apples, pears and raw carrots. CONCLUSIONS The results support the temporal association between tooth loss and detrimental changes in dietary intakes, which could contribute to increased risk of developing chronic diseases. PRACTICE IMPLICATIONS Dietary evaluation and recommendations can be incorporated into dental visits to provide a greater benefit to patients.

Abstract
Several earlier studies have suggested that development of coronary heart disease (CHD) is causally related to oral infections. The aim of this study was to investigate the association between oral health indicators and CHD deaths. Out of a nationally representative sample, 6527 men and women aged 30-69 years participated in the health examination with a dental check. Detailed oral health data included caries, periodontal and dental plaque status, presence of remaining teeth, and various types of dentures. Over a mean 12-year follow-up, persons dying of CHD were older and more often smoked, had hypertension, hypercholesterolemia, diabetes, and only a basic education compared with other persons. In univariate analyses, several oral health indicators were associated with CHD deaths. Adjustment for the established CHD risk factors reduced all these associations to statistical non-significance. The associations between oral health indicators and CHD are mostly explained by confounding factors, particularly those relating to health behavior.

Abstract
Certain medical conditions and their accompanying drug treatment do have an impact upon oral structures and the delivery of dental care. Recent evidence suggests that oral health could be a significant risk factor for coronary artery disease. Many medical conditions can affect dental care are often over-stated and lack an evidence base. Examples include the need for antibiotic cover in patients at risk from infective endocarditis and the necessity to provide supplementary corticosteroids for those patients on longterm steroid therapy. By contrast, certain systematic drug treatments can have a profound affect on the oral tissue. The most obvious is drug-induced gingival overgrowth. Drugs frequently implicated in this unwanted effect include phenytoin, ciclosporin and the calcium channel blockers. Several risk factors for drug-induced overgrowth have been identified and include age, sex, peridontal variables and a range of drug pharmacokinetic variables. The relationship between oral health and coronary artery disease opens up a potentially new vista for the delivery of oral care. Although the association is convincing, casualty has not been established. If casualty for this relationship can be confirmed then the delivery of dental care and the promotion of oral health will receive a significant impetus.

Abstract
The objective of this systematic review was to determine whether periodontal disease is associated with an increased risk for coronary heart disease (CHD) and preterm and/or low birth weight deliveries (PLBW). A literature search was performed to identify cross-sectional, case-control, and cohort studies as well as clinical trials addressing different aspects of periodontal disease (clinical, microbial, immunological) and clinical outcomes of CHD or PLBW. The periodontitis-CHD association was evaluated in eight cohort, four case-control- and four cross-sectional studies. Meta-analysis was not performed due to the extensive heterogeneity of the studies, particularly with regard to periodontitis measures, which varied from full mouth probing assessments to questionnaires. Percentage-wise, 50% of the cohort studies (4/8), 75% of the case-control studies (3/4) and 50% of the cross-sectional studies (2/4) reported a significant association between clinical measures of periodontitis and CHD (excess risk ranged from 0 to 3.3-fold). The periodontitis-PLBW association was evaluated in one cohort and two case-control studies. The cohort study as well as one of the two case-control studies reported a significant association between periodontitis and PLBW (odds ratios 4.4-7.9). From two additional case-control studies microbiological data could be extracted. Bacteroides forsythus was found to be associated with PLBW in both studies. In conclusion, the evidence linking periodontitis with an increased risk for CHD and PLBW is limited. There is a clear need for new, well designed observational and intervention studies to confirm the thus far observed associations, explore the validity of the associations in diverse populations, establish whether they are causal in nature and determine potential benefits of periodontal intervention in reducing the risk for these conditions.

Abstract
An association between periodontal infection and CVD has been revealed in some epidemiologic studies, whereas other studies were unable to demonstrate such an association. A link between the two diseases may be explained by shared established or nonestablished risk factors. Future studies with extended control of confounding factors and intervention studies may add to the understanding of a possible relationship between the diseases. In some cases, IE is caused by dental plaque bacteria. Several studies are suggestive of oral bacteria causing respiratory infection. The pathogenesis and course of a number of other diseases including DM and rheumatoid arthritis have been associated wish periodontitis, but more research is necessary to elucidate possible pathogenic interactions.

Abstract
BACKGROUND AND OBJECTIVE Tooth loss has been associated with cardiovascular disease (CVD), but the mechanisms are unclear. We evaluated the association of total tooth loss with prevalent CVD in men and women; as well as with citrus fruit consumption, plasma vitamin C, and inflammatory and thrombotic variables. METHODS We used an age-and sex-stratified population survey, of men and women aged 25-74 years, in North Glasgow. RESULTS Thirty-eight percent of women and 29% of men were edentulous. Total tooth loss was associated with prevalent CVD in both sexes. After adjustment for major potential confounders (age, sex, smoking, and social class), the odds ratio (95% CI) for prevalent CVD was 1.55 (1.13, 2.13) in the edentulous. Total tooth loss was also associated with low citrus fruit consumption and low plasma vitamin C levels, increased plasma C-reactive protein in men, and with increased plasma interleukin-6, fibrinogen, and factor VIII levels in women. CONCLUSION Prevalent CVD is associated with total tooth loss. Possible mechanisms include low intake of citrus fruit, and hence, low plasma vitamin C levels, and a predisposition to low-grade inflammation and thrombosis. It may be prudent to ensure adequate vitamin C intake in people with no teeth.

Abstract
OBJECTIVE The purpose of this study was to determine whether periodontal disease is associated with endothelial dysfunction and systemic inflammation. Epidemiological studies suggest that severe periodontal disease is associated with increased cardiovascular disease risk, but the mechanisms remain unknown. METHODS AND RESULTS We assessed flow-mediated dilation and nitroglycerin-mediated dilation of the brachial artery using vascular ultrasound in 26 subjects with advanced periodontal disease and 29 control subjects. The groups were matched for age and sex, and patients with hypercholesterolemia, diabetes mellitus, hypertension, and history of cigarette smoking were excluded. We also examined serum levels of C-reactive protein using an established high-sensitivity method. Subjects with advanced periodontal disease had lower flow-mediated dilation compared with control patients (7.8+/-4.6% versus 11.7+/-5.3%, P=0.005). Nitroglycerin-mediated dilation was equivalent in the two groups. Subjects with advanced periodontitis exhibited higher serum levels of high-sensitivity C-reactive protein compared with healthy controls patients (2.3+/-2.3 versus 1.0+/-1.0 mg/L, P=0.03). CONCLUSIONS Subjects with advanced periodontal disease exhibit endothelial dysfunction and evidence of systemic inflammation, possibly placing them at increased risk for cardiovascular disease.

Abstract
BACKGROUND Destructive periodontal diseases have been associated with an increased risk of atherosclerotic complications; however, the potential mechanisms are yet to be defined. Inflammation plays a central role in atherosclerosis since C-reactive protein (CRP), an acute-phase protein monitored as a marker of inflammatory status, has been identified as a major risk factor for atherosclerotic complications. Recent reports that destructive periodontal diseases can increase CRP values present the possibility that the acute-phase response may link these 2 disease processes. The objective of the present investigation was to determine the effect of destructive periodontal disease status, severity, and progression on components of the acute-phase response in an urban minority population. METHODS Clinical measurements recorded included probing depth, attachment level, gingival erythema, bleeding upon probing, suppuration, and plaque. Disease progression was defined as a >2 mm loss of attachment 2 months post-baseline. Serum antibody was measured by enzyme-linked immunosorbent assay. CRP was measured using a high-sensitivity CRP (hsCRP) assay. A commercial laboratory measured serum glucose (non-fasting), albumin, cholesterol, high-density lipoprotein (HDL), triglycerides, low-density lipoprotein (LDL), and iron. RESULTS Increased serum IgG antibody to Porphyromonas gingivalis, but not to 5 other species, was associated with periodontal disease status, increased severity, and progression as were age, male gender, and smoking. Cholesterol and LDL were increased in disease, and HDL and iron were increased in health. hsCRP, glucose, and cholesterol increased with disease progression. By regression analysis, IgG antibody to P. gingivalis correlated with age, probing depth, and hsCRP, and negatively correlated with albumin and iron. By logistic regression, subjects who experienced multiple sites of disease progression and elevated antibody to P. gingivalis increased the odds ratio of hsCRP>2.08 mg/l by 14.1 and 5.6, respectively. CONCLUSION These results suggest that destructive periodontal disease and disease progression are associated with changes in serum components consistent with an acute-phase response.

Abstract
BACKGROUND Epidemiological studies have reported a strong association between C-reactive protein (CRP) and cardiovascular diseases (CVD). Elevated CRP levels have been observed both in dentate individuals with chronic dental infections like periodontal disease and in those edentulous. The mechanisms behind these observations, especially the reasons for the elevation of CRP in the edentulous, are poorly understood. The comparative data on the importance of these inflammatory conditions in the oral cavity as causes of elevated CRP levels and CVD risk factors are also limited. OBJECTIVE To determine if edentulism is associated with increased levels of CRP and investigate the possible mechanism for this association; and to study the influence of periodontal disease and edentulism on 10-year mortality. SUBJECTS Of the 364 subjects aged 76, 81, and 86 years in 1990, 196 were dentate and 168 edentulous. By December 1999, 179 had died, almost half (n = 87) of them due to cardiovascular disease. RESULTS Significantly more of the edentulous subjects had elevated (> or = 3 mg/L) CRP levels as compared to those with at least 20 teeth (p < 0.01). They also had high salivary microbial counts (p < 0.05), and more mucosal lesions (p < 0.0001) than those with at least 20 teeth. In multivariate analysis, high microbial counts (OR 2.3, CI 1.06-5.05) and mucosal lesions (OR 2.18, CI 1.03-4.61) were significantly associated with elevated CRP levels. The risk for all-cause mortality was non-significantly elevated among the edentulous (RR 1.48, CI 0.95-2.31) and dentate with periodontal disease (RR 1.58, CI 0.96-2.61). CVD mortality was significantly higher among the dentate with periodontal disease (RR 1.97, CI 1.01-3.85) when compared with dentate without periodontal disease. CONCLUSION Among the edentulous, chronic infections like denture-related mucosal lesions are important determinants of elevated CRP, comparable to periodontal disease in the dentate. Elevated CRP per se and edentulism were not significantly associated with increased mortality. Periodontal disease was, however, still associated with a two-fold CVD mortality in this very old population.

Abstract
OBJECTIVE The purpose of this study was to analyze published studies and abstracts in order to provide a quantitative summary of periodontal disease as a risk factor for cardiovascular disease and to explore the possible causes for conflicting results in the literature. STUDY DESIGN We searched all published literature on the Medline literature search engine since 1980. An additional search was performed with bibliographic citations from each article. Nine cohort studies (8 prospective and 1 retrospective), in which relative risks (RRs), CIs, and P values were reported or could be calculated were included. Four researchers independently extracted RRs, CIs, and P values from each study and evaluated the degree of confounding adjustment. The combined result was calculated with weighted average, and sources of disparity were tested with regression analyses. RESULTS The summary RR was 1.19 (95% CI, 1.08 1.32), indicating a higher risk of future cardiovascular events in individuals with periodontal disease compared with those without. In an analysis stratified to individuals of </=65 years of age, the RR was 1.44 (95% CI, 1.20 to 1.73). When the outcome was restricted to stroke only, the RR was 2.85 (95% CI, 1.78 to 4.56). In the metaregression analysis, the effects of residual confounding caused an overestimate of the results by 12.9% and, with a proxy for periodontal disease, caused an underestimate of 29.7%. CONCLUSIONS Periodontal disease appears to be associated with a 19% increase in risk of future cardiovascular disease. This increase in RR is more prominent (44%) in persons aged </=65 years. Although the increment of risk between subjects with or without periodontal disease in the general population is modest, at around 20% because nearly 40% of population has periodontal disease, this modest increase may have a profound public health impact.

Abstract
BACKGROUND Cardiovascular diseases represent a widespread heterogeneous group of conditions that have significant morbidity and mortality. The various diseases and their treatments can have an impact upon the periodontium and the delivery of periodontal care. AIM In this paper we consider three main topics and explore their relationship to the periodontist and the provision of periodontal treatment. METHOD The areas reviewed include the effect of cardiovascular drugs on the periodontium and management of patients with periodontal diseases; the risk of infective endocarditis arising from periodontal procedures; the inter-relationship between periodontal disease and coronary artery disease. RESULTS AND CONCLUSIONS Calcium-channel blockers and beta-adrenoceptor blockers cause gingival overgrowth and tooth demineralisation, respectively. Evidence suggests that stopping anticoagulant therapy prior to periodontal procedures is putting patients at a greater risk of thromboembolic disorders compared to the risk of prolonged bleeding. The relationship between dentistry and infective endocarditis remains a controversial issue. It would appear that spontaneous bacteraemia arising from a patient's oral hygiene practices is more likely to be the cause of endocarditis than one-off periodontal procedures. The efficacy of antibiotic prophylaxis is uncertain (and unlikely to be proven), and the risk of death from penicillin appears to be greater than the risk of death arising from infective endocarditis. Finally, the association between periodontal disease and coronary artery disease has been explored and there seem to be many issues with respect to data handling interpretation. Many putative mechanisms have been suggested; however, these only further highlight the need for intervention studies.

Abstract
AIMS Recent epidemiological work suggests an association between periodontal disease severity and cardiovascular disease risk. This study aimed to ascertain if circulating levels of cardiovascular and systemic inflammatory markers could be modified following treatment of periodontal disease. METHOD Adult subjects were recruited from those awaiting periodontal treatment and randomised to either immediate (test, n=24) or delayed treatment (control, n=15). Demographic and clinical data were collected and venous blood was taken before and either 6 weeks after completion of treatment or after an equivalent 3-month control period. Periodontal examination included probing depth, loss of attachment, plaque scores and bleeding scores. Blood was analysed to determine serum and plasma fibrinogen, C-reactive protein, sialic acid, tumour necrosis factor-alpha and interleukin -6 and -1beta. Effects of treatment were assessed by paired tests and analysis of variance by treatment group with baseline covariates. RESULTS Treatment improved plaque and bleeding scores and reduced probing depths (p<0.002). However, there were no statistically significant changes in levels of any of the systemic markers. CONCLUSION Improvement in periodontal health did not influence the levels of vascular markers.

Abstract
BACKGROUND, AIMS Over the past 10 years several studies have been published pointing towards a relationship between periodontal disease and various systemic disorders or diseases. The purpose of this retrospective study was to investigate the occurrence of self-reported systemic disorders in patients referred to a specialist clinic for periodontal treatment and to explore possible relationships between general health and periodontal disease severity in this population. MATERIAL AND METHODS Data were collected from the dental records and the health questionnaires of 1006 subjects. Stepwise multiple linear regression analyses were adopted to calculate correlations between systemic disorders as independent variables and number of remaining teeth and the relative frequency of periodontal pockets of 5 mm or more, respectively, as the dependent variable. RESULTS The number of remaining teeth was significantly and positively correlated to the presence of cardiovascular disease, diabetes and rheumatoid disease after adjustment for age, sex and smoking. The relative frequency of diseased sites, however, was not significantly correlated to any one of the investigated systemic health disorders. CONCLUSION No significant associations between investigated systemic disorders and periodontal disease severity were found if the relative frequency of deep periodontal pockets was used as the clinical parameter for periodontal disease severity. However, cardiovascular disease, diabetes and rheumatoid disease were found to be significantly correlated to number of lost teeth, which may represent one aspect of periodontal health. This result held true in nonsmokers only.

Abstract
BACKGROUND Many studies have reported the association between poor oral health and coronary heart disease or stroke, but few of them evaluated peripheral arterial disease (PAD). Hence, in this study we examined the associations between oral health and PAD. METHODS AND RESULTS In the prospective study of 45,136 eligible male health professionals free of cardiovascular diseases at baseline, we identified 342 cases of PAD during a 12-year follow-up period. We evaluated the association between different measures of oral diseases and the occurrence of PAD. Baseline number of teeth was not related to the risk of PAD, but cumulative incident tooth loss was significantly associated with elevated risk of subsequent occurrence of PAD. The relative risk for history of periodontal disease was 1.41 (95% CI, 1.12 to 1.77) and for any tooth loss during the follow-up period was 1.39 (95% CI, 1.07 to 1.82), controlling for traditional risk factors of cardiovascular disease. Among men with a history of periodontal diseases, the relative risk of tooth loss increased to 1.88 (95% CI, 1.27 to 2.77), whereas no association was found between tooth loss and PAD among those without periodontal diseases (RR, 0.92; 95% CI, 0.61 to 1.38). We further explored the potential induction period of tooth loss and found that tooth loss in the previous 2 to 6 years was most strongly associated with PAD. CONCLUSIONS We found that incident tooth loss was significantly associated with PAD, especially among men with periodontal diseases. The results support a potential oral infection-inflammation pathway.

Abstract
Chronic periodontitis has been associated with an increased risk for cardiovascular disease. Left ventricular mass is an established independent predictor of cardiovascular disease. In the present cross-sectional study, we tested the association between periodontitis and left ventricular mass in subjects with essential hypertension. One hundred four untreated subjects with essential hypertension underwent clinical examinations, including echocardiographic study, laboratory tests, and assessment of periodontal status according to the community periodontal index of treatment needs (CPITN). With increasing severity of periodontitis, there was a progressive increase in left ventricle mass. Mean values (g/height2.7) were 39.0 (+/-2.7) in CPITN 0 (periodontal health), 40.2 (+/-6.4) in CPITN 1 (gingival bleeding), 42.7 (+/-6.8) in CPITN 2 (calculus), 51.4 (+/-11.7) in CPITN 3 (pockets 4 to 5 mm), and 76.7 (+/-11.3) in CPITN 4 (pockets > or =6 mm) (overall F 51.2; P<0.0001). Body surface area (P=0.04), systolic (P<0.0001) and diastolic (P<0.01) blood pressure, and left ventricular mass (P<0.0001) were determinants of a composite of CPITN 3 and 4. In a multivariate logistic analysis, left ventricular mass was the sole determinant (P<0.0001) of CPITN stages 3 and 4. Our findings suggest a direct association between severity of periodontitis and left ventricular mass in subjects with essential hypertension. Periodontal evaluation might contribute to refine cardiovascular risk assessment in hypertensive subjects.

Abstract
This article reports a critical analysis of epidemiologic studies that evaluated periodontal disease as a cause of cardiovascular disease. Thirty-five studies were identified through a manual search of the special abstracts volumes of the Journal of Dental Research, as well as an electronic search on MEDLINE, LILACS, and ISI and inspection of the articles' bibliographies. Inclusion criteria were: articles in any language published between 1989 and 2000 reporting the presence or absence of an association between periodontal and cardiovascular diseases. Available studies are scarce, and interpretations are limited by potential bias and confounding. The studies analyzed (whether separately or jointly) fail to provide convincing epidemiologic evidence for a causal association between periodontal and cardiovascular diseases. Although the possibility that oral diseases can cause cardiovascular diseases cannot be discarded, until better data are available, periodontal disease should not be incriminated as a cause of cardiovascular disease.

Abstract
OBJECTIVE Little is known about the dental health and health behavior of patients referred for open-heart surgery because of severe heart disease. Yet, coronary atherosclerosis has been suggested to be an inflammatory disease in which chronic dental infections may trigger pathogenic mechanisms in the walls of arteries. In epidemiological studies periodontal disease in particular has been linked with coronary heart disease (CHD). STUDY DESIGN We set out to investigate by means of clinical examination, x-ray, and questionnaire the oral health status, health-related behavior, and conceptions of 256 CHD patients referred for open-heart surgery in the Kuopio University Hospital. The patients' heart disease was New York Heart Association grades II-IV. For comparison, 250 age- and sex-matched non-CHD patients were also studied. Differences between groups were analyzed conventionally and with the Total Dental Index (TDI), which uses linear modeling and logistic regression analyses to summarize periodontal factors and other signs of oral infections. We expected to find neglected dental care and worse oral health situation among the CHD patients. RESULTS Edentulousness was seen in 35% of the CHD group and in 15% of the non-CHD group (P < .001). The CHD group had significantly lower number of teeth (8.8 +/- 9.1) than the non-CHD group (17 +/- 10.5; P < .001). No dental appointment in the past 10 years was reported in 66% of the CHD patients and 35% of the non-CHD patients. Forty-nine percent of the CHD group and 69% of the non-CHD group had had a dental visit within the past 2 years (P < .001). Daily tooth brushing was reported by 46% of the CHD group and 56% of the non-CHD group (P < .05). Only 2% of the CHD group and 8% of the non-CHD group flossed daily (P < .001). TDI scores were significantly higher in the edentulous than in the dentate study groups (P < .001), but no difference was observed between CHD and non-CHD patients of the same dentate or edentulous status. Mean TDI score was 3.2 +/- 0.8 in edentulous CHD patients and 3.1 +/- 0.4 in edentulous non-CHD patients; the scores in the dentate patients were 2.5 +/- 0.9 in the CHD group and 2.4 +/- 2.0 in the non-CHD group. The TDI score appeared almost significant a predictor of CHD when used as a dependent variable in logistic regression analysis (P = .08). CONCLUSION Worse oral health status and less satisfactory oral health behavior were observed in the CHD patients than among the cardiologically healthy.

Abstract
Oral infections and cardiovascular diseases share common biological and behavioral risk factors. Psychosocial determinants could act as a link between general health behavior and dental health behavior. Our objective was to study optimism and life satisfaction as determinants of general and dental health behavior and to evaluate whether these are connected with cardiovascular risk factors and dental diseases. The 1966 Northern Finland Birth Cohort (N = 12,058) is a general population birth cohort. In a postal questionnaire, respondents (N = 8690) were asked about their health behavior and dental status. Cardiovascular risk factors were assessed in health examinations (N = 6033). Generalized linear regression models were used in analysis. The results showed that health orientation increases with strengthening life satisfaction and optimism. Dental health behavior and general health behavior were associated with both cardiovascular risk factors and self-reported dental diseases, which support the assumption that they share a common behavioral background.

Abstract
BACKGROUND AND PURPOSE Periodontal and other infections have been suggested as potential risk factors for stroke. This study evaluates periodontal disease and tooth loss as risk factors for ischemic stroke. METHODS The study population consisted of 41 380 men who were free of cardiovascular disease and diabetes at baseline. Periodontal disease history was assessed by mailed validated questionnaires. During 12 years of follow-up, stroke incidence was assessed and subclassified by use of medical history, medical records, and imaging reports. Hazard ratios (HRs) were adjusted for age, amount smoked, obesity, alcohol, exercise, family history of cardiovascular disease, multivitamin use, vitamin E use, profession, baseline reported hypertension, and hypercholesterolemia. Sex and socioeconomic status were inherently controlled for by restriction. Confounding variables were updated in the analyses for each 2-year follow-up interval. RESULTS We documented 349 ischemic stroke cases during the follow-up period. Men who had < or =24 teeth at baseline were at a higher risk of stroke compared to men with > or =25 teeth (HR=1.57; 95% CI, 1.24 to 1.98). There was little evidence of an increased risk with recent tooth loss during follow-up. A modest association was seen between baseline periodontal disease history and ischemic stroke (HR=1.33; 95% CI, 1.03 to 1.70). Addition of dietary factors to the model changed the HR only slightly. CONCLUSIONS Our results suggest that periodontal disease and fewer teeth may be associated with increased risk of ischemic stroke.
