Abstract
Background A positive link between periodontitis and chronic systemic disease has been indicated. However, few studies focused on the loss of teeth. Our analysis aims to analyze the relationship of periodontitis and number of teeth with the risk of coronary heart disease (CHD). Material/Methods A meta-analysis was conducted on qualified data extracted from the PubMed, Embase, and Cochrane Library databases. Only cohort studies were included in this study. We screened articles that assessed the periodontal condition and teeth number as well as the incidence or mortality of CHD. Hazard ratio (HR) and relative risk (RR) were calculated by Stata SE software. Results A total of 11 prospective studies with over 200 000 total participants were analyzed. Ten studies reported on periodontitis and CHD, and 4 studies included data on number of teeth. After adjusting for multivariate factors, there was a significant association between periodontitis and the risk of CHD (RR, 1.18; 95% confidence interval [CI], 1.10–1.26); the RR of CHD in the edentulous population was 1.20 (95% CI, 1.08–1.34). Moreover, results on the RR values for number of teeth were as follows: 24–17 teeth (RR, 1.12; 95% CI, 1.05–1.19); 16–11 (RR, 1.28; 95% CI, 1.15–1.42); and ≤10 (RR, 1.55; 95% CI, 1.43–1.69). Conclusions Our study showed that periodontitis is a risk factor for CHD and that the number of removed teeth is positively correlated with the risk of CHD. During clinical assessment, both factors need to be considered as factors associated with cardiovascular risks.

Abstract
Background: Chronic periodontitis, an inflammatory disease, is closely related to certain systemic conditions such as cardiovascular diseases, obesity, and Type 2 diabetes mellitus. These conditions, occurring as comorbidities, synergically affect periodontal tissues. Aim: This study aims to examine whether chronic gingivitis and chronic generalized severe periodontitis in patients with Type 2 diabetes mellitus are associated with increased left ventricular mass (LVM). Materials and Methods: A total of 45 patients affected with Type 2 diabetes mellitus were recruited and divided into three groups with 15 patients each according to their periodontal status: Group I consisting of healthy individuals, Group II consisting of chronic gingivitis, and Group III consisting of chronic generalized severe periodontitis. They were assessed clinically, biochemically, and echocardiographically. LVM was calculated according to Devereux formula and was indexed to height. Results: The differences in the means for LVM and LVM index (LVMI) were statistically significant in three groups with a P = 0.006 and 0.014, respectively. After adjusting for the confounders, the mean values of LVM in Group I, II, and III were 149.35 ± 35.51 g, 147.95 ± 31.59 g, and 156.36 ± 36.57 g, respectively and for LVMI, the mean values were 43.61 ± 12.16 g/m2.7 (Group I), 47.12 ± 10.84 g/m2.7 (Group II), and 46.34 ± 12.55 g/m2.7 (Group III). Conclusions: A positive association between chronic generalized severe periodontitis and increased LVM in Type 2 DM patients was observed, suggesting the role of periodontal disease in the left ventricular hypertrophy.

Abstract
OBJECTIVES The objective of this study was to systematically review the epidemiological evidence for an association between periodontitis (PD) and incident atherosclerotic cardiovascular disease (ACVD), including coronary heart disease (CHD), cerebrovascular disease and peripheral arterial disease. METHODS Systematic review of cohort and case-control studies on the association of clinically or radiographically diagnosed PD and ACVD. RESULTS Overall, 12 studies were included in this study (six studies on CHD, three studies on cerebrovascular disease, two studies on both coronary heart and cerebrovascular disease mortality and one study on peripheral arterial disease).All but one study reported positive associations between various periodontal disease measures and the incidence of ACVD, at least in specific subgroups. The association was stronger in younger adults and there was no evidence for an association between PD and incident CHD in subjects older than 65 years. Only one study evaluated the association between PD and secondary cardiovascular events. CONCLUSIONS There is evidence for an increased risk of ACVD in patients with PD compared to patients without. However, this may not apply to all groups of the population. There is insufficient evidence for an association between PD and the incidence of secondary cardiovascular events.

Abstract
Large proportion of Asian populations have moderate to severe periodontal disease and a substantial number are anticipated to be at high risk of cardiovascular diseases (CVD). This study reviews epidemiology and association of periodontal and CVDs from the South-Asian region. Observational studies and clinical trials published during January 2001-December 2012 focusing association between periodontitis and CVDs in South-Asian countries were retrieved from various databases and studied. Current evidence suggests that both periodontal and CVDs are globally prevalent and show an increasing trend in developing countries. Global data on epidemiology and association of periodontal and CVDs are predominantly from the developed world; whereas Asia with 60% of the world's population lacks substantial scientific data on the link between periodontal and CVDs. During the search period, 14 studies (5 clinical trials, 9 case-controls) were reported in literature from South-Asia; 100% of clinical trials and 77% case-control studies have reported a significant association between the oral/periodontal parameters and CVD. Epidemiological and clinical studies from South-Asia validate the global evidence on association of periodontal disease with CVDs. However, there is a need for meticulous research for public health and scientific perspective of the Periodontal and CVDs from South-Asia.

Abstract
AIM: To investigate whether periodontal disease (PD) is associated with increasing coronary heart disease (CHD) risk by performing a meta-analysis.
METHODS: Two authors independently searched PubMed and China National Knowledge Infrastructure up to January 10th, 2013 for relevant case-control studies that investigated the association between PD and CHD. After quality assessment using Newcastle-Ottawa Scale and data extraction by two independent authors, the overall and subgroup meta-analyses were performed and publication bias were examined using the Comprehensive Meta-Analysis V2 software. Potential publication bias was assessed using visual inspection of the funnel plots, Egger linear regression test, and trims and fill method.
RESULTS: Finally 38 relevant case-control studies were identified, involving 4950 CHD patients and 5490 controls. Eleven studies were rated low quality and 27 were high quality. Based on random-effects, a significant association was identified between PD and CHD (OR 3.79, 95%CI: 2.23-6.43, P < 0.001, I2 = 98.59%), and sensitivity analysis showed that this result was robust. Subgroup analyses according to adjusted/unadjusted ORs, source of control, methodological quality, end point, assessment of PD/CHD, and ethnicity also indicated a significant association. Publication bias was detected, and the estimated OR including the “missing” studies did not substantially differ from our estimate with adjustment for missing studies (OR 4.15, 95%CI: 2.62-6.54, P < 0.001).
CONCLUSION: Based on the meta-analysis, PD is probably associated with CHD risk independently and significantly.

Abstract
Background The aim of this investigation was to assess the state of oral health of patients with acute coronary syndrome (ACS) and to compare this with that of a provably healthy control group (H). Methods 33 patients who were receiving treatment as inpatients following acute myocardial infarction or unstable angina pectoris took part in the study (ACS-group). A healthy control group (H-group) made up of blood donors, was formed following matching for age, gender, and smoking habit with the study patient group. The dental investigation consisted of the dental status (DMF-T), a plaque-Index (PI), an assessment of gingival inflammation (GI) and periodontal situation (Periodontal Screening Index: PSR®/PSI), and attachment loss (AL). Statistical evaluation: t-test, Mann–Whitney-test and chi- squared test (level of significance p < 0.05). Results The mean DMF-T of the ACS-group (18.7 ± 6.8) and the H-group (19.4 ± 5.1) showed no difference (p = 0.7). Although, in the ACS-group the average loss of teeth (M-T: 8.4 ± 5.2) was higher than in the H-group (M-T: 5.8 ± 6.6) the difference was not significant (p = 0.2). Whereas with the PI no difference between the two groups was found (p = 0.9), the ACS-group showed significantly more signs of inflammation (GI) than the H-group (p = 0.045). In the case of PSR®/PSI, there was no difference between the two groups (p = 0.7). With regard to AL, no difference was revealed between ACS- and H-group (p = 0.2). Conclusion Although, the state of oral health of the ACS-group differed only insignificantly from that of control, patients with ACS showed more signs of gingival inflammation and a higher loss of teeth.

Abstract
BACKGROUND Both chronic plaque psoriasis and periodontitis have an increasing prevalence worldwide and have been associated with the metabolic syndrome; however limited information is available on their association. OBJECTIVE To evaluate the possible association of severe periodontitis and chronic plaque psoriasis. METHODS This was a hospital based case-control study. Chronic plaque psoriasis patients and age- and gender-matched controls have been recruited. Baseline demographic data have been recorded. To explore correlations between different dichotomous variables the Sperman Rho correlation coefficient was used. Correlations were further explored non-parametrically and univariate and multivariate logistic regression was utilized after adjustment for the effect of confounders. RESULTS During the study enrollment period 100 patients with CPP and 100 age- and gender-matched controls were included in this study. Mean age for both groups was 57.2 ± 5.3 years. 43% of patients and controls were males. Significant correlations where noted between psoriasis and 1) periodontitis (rho = 0.219, P = 0.02) and 2) metabolic syndrome (rho = 0.191, P = 0.07) using Spearman's Rho correlation co-efficient. Univariate logistic regression reported significant relations between psoriasis and periodontitis (OR = 3.329, 95%CI: 1.513-7.324, P = 0.003) and psoriasis and metabolic syndrome (OR = 2.293, 95%CI: 1.250-4.207, P = 0.007). On the contrary, a non-significant relation between psoriasis and active smoking status was detected (OR = 1.041, 95%CI: 0.597-1.817, P = 0.887). In a multivariate analysis model we found a significant correlation of psoriasis and periodontitis when controlled for the presence of metabolic syndrome (OR: 2.486, 95%CI: 1.002-5.842, P = 0.049). CONCLUSION Periodontitis may be associated with psoriasis but further studies are required to elucidate their relationship in the context of the biologic plausibility.

Abstract
A link between oral health and cardiovascular disease has been proposed for more than a century. Recently, concern about possible links between periodontal disease (PD) and atherosclerotic vascular disease (ASVD) has intensified and is driving an active field of investigation into possible association and causality. The 2 disorders share several common risk factors, including cigarette smoking, age, and diabetes mellitus. Patients and providers are increasingly presented with claims that PD treatment strategies offer ASVD protection; these claims are often endorsed by professional and industrial stakeholders. The focus of this review is to assess whether available data support an independent association between ASVD and PD and whether PD treatment might modify ASVD risks or outcomes. It also presents mechanistic details of both PD and ASVD relevant to this topic. The correlation of PD with ASVD outcomes and surrogate markers is discussed, as well as the correlation of response to PD therapy with ASVD event rates. Methodological issues that complicate studies of this association are outlined, with an emphasis on the terms and metrics that would be applicable in future studies. Observational studies to date support an association between PD and ASVD independent of known confounders. They do not, however, support a causative relationship. Although periodontal interventions result in a reduction in systemic inflammation and endothelial dysfunction in short-term studies, there is no evidence that they prevent ASVD or modify its outcomes.

Abstract
BACKGROUND Evidence on association of oral health and coronary heart diseases (CHD) is mounting in the literature. This study was designed to observe an association between status of oral health and cardiac diseases in Pakistani adults. MATERIALS AND METHODS A case-control study was conducted on CHD and non-CHD adults aged >30 years. Age-gender matched individuals without CHD, fulfilling the inclusion criteria as for CHD patients were selected for comparison. Bleeding on probing (BOP), periodontal pocket depth (PPD) and tooth loss were noted as oral health parameters. RESULTS 45 CHD patients and 35 non-CHD individuals were examined. 53.75% were males and 46.25% females, 37.5% subjects were uneducated, 65% belonged to lower income group, 58.75% subjects were ≥obese and 88.75% were non-smokers. Mean of percent sites of BOP (P =0.007), PPD (P =0.031) and tooth loss (P =0.021) were significantly higher in study group. In stepwise logistic regression analysis, BOP and tooth loss showed a significant positive association with CHD; however, association of PPD was not significant. CONCLUSION Oral health parameters were significantly higher in CHD patients. Bleeding on probing and tooth loss was positively associated with CHD after adjusting for other socio-demographic variables.

Abstract
Background The aim was to investigate the extent to which it is possible to diagnose suspected carotid calcification from dental panoramic radiography (PR) and to establish an association to periodontal risk. Methods 824 PRs from one dental practice were investigated. Parameters considered were gender, age, bone loss - age index, tooth loss, periodontal risk and suspected carotid calcification (left, right, both sides). Periodontal risk was classified: low risk (under 4 missing teeth, bone loss - age index under 0.5), moderate risk (5 to 8 missing teeth and/or bone loss - age index 0.5 to 1.0) and high risk (more than 9 missing teeth and or bone loss - age index greater than 1.0). Results Of 824 patients, 349 were male (42.4%) and 475 female (57.6%); the mean age was 48.32 ± 16.52 years. In 9.0% (n = 74) of PRs, suspected carotid calcification was diagnosed (right: 5.5%, left: 2.3%, both sides: 1.2%). The mean tooth loss was 4.16 ± 5.39 teeth. In the case of 282 patients (34.2%), there was a low, in 335 patients (40.7%) a moderate, and in 207 patients (25.1%) a high periodontal risk. There was a significant correlation found between number of cases of suspected carotid calcification and periodontal risk, tooth loss and age (p = 0.0001). However, only age showed a significant association (OR: 4.9; CI: 2.4-9.8; p < 0.0001) in contrast to periodontal risk (OR 1.4; CI: 0.9-2.4). Conclusion PR can provides indication of carotid calcification as a secondary (chance) finding. In addition, periodontal risk may be correlated with positive findings of carotid calcification.

Abstract
Background and aims
Recent epidemiological studies have shown that individuals with periodontitis have a significantly higher risk of developing coronary heart disease, which might be attributed to the complex microbiota in the dental plaque. Periodontopathogens have been reported as risk factors for cardiovascular disease. This study evaluated association of chronic periodontitis and periodontopathogens with CRP in systemically healthy Serbian adults.
Materials and methods
Serum C-reactive protein levels were measured in 24 patients with moderate periodontitis, 26 patients with severe periodontitis, and 25 periodontally healthy subjects. Periodontal health indicators included gingival bleeding on probing and periodontal disease status. Patients with moderate periodontitis had low attachment loss and pocket depths of <4 mm. Patients with severe periodontitis had high AL and pocket depth of >5 mm. The control group with healthy gingiva had gingival sulcus of <2 mm and no attachment loss. Presence of periodontopathogens in subgingival plaque samples was analyzed by polymerase chain reaction.
Results
The periodontal parameters and CRP levels were significantly higher in the patients with periodontitis. Patients who had both severe and moderate periodontitis had higher mean CRP levels. The percentage of subjects with elevated CRP leves of >5 mol/L was greater in the higher clinical AL group compared to the group with less attachment loss. Presence of periodontopathogens was also associated with elevated CRP levels and poor periodontal status.
Conclusion
PD and subgingival periodontopathogens are associated with increased CRP levels. These findings suggest that periodontal infection may contribute to systemic inflammatory burden in otherwise healthy individuals.

Periodontitis has been identified as a potential risk factor for systemic pathologies such as cardiovascular disease (CVD). The aims of this investigation were to assess the relationship between periodontitis and systemic inflammatory factor, as well as to discover whether there is a relation to the severity of periodontitis and to the periodontopathogens. Periodontal examinations and serum C-reactive protein (CRP) level measurements were performed in 50 patients with periodontitis. Periodontal health indicators included the gingival bleeding on probing index and periodontal disease status. The patients with moderate periodontitis had low attachment loss and pocket depth <4 mm. The patients with severe periodontitis had high attachment loss and pocket depth >5 mm. The control group comprised 25 volunteers with healthy gingiva, gingival sulcus <2 mm and no attachment loss. The presence of Porphyromonas gingivalis and Aggregatibacter actinomycetemcomitans in subgingival plaque samples was analysed by the polymerase chain reaction (PCR) method. The periodontal parameters and CRP levels were significantly higher in the patients with periodontitis. Patients who had severe periodontitis, with high levels of mean clinical attachment loss, and subjects with moderate periodontitis had higher mean CRP levels. The percentage of subjects with elevated levels of CRP >5 mg/l was greater in the higher clinical attachment loss group compared to the group with lower attachment loss. The presence of P. gingivalis and A. actinomycetemcomitans were also associated with elevated CRP levels and poor periodontal status. Periodontitis and the presence of P. gingivalis are associated with an enhanced inflammatory response expressed by higher CRP levels. The association of periodontitis with CRP levels appears to be a contributing factor for CVD and might be a possible intermediate pathway in this association.

Abstract
BACKGROUND Evidence suggests an association between periodontal disease and coronary heart disease (CHD). C-reactive protein (CRP), fibrinogen, and white blood cell (WBC) counts are markers of inflammation, and their systemic levels have been associated with CHD risk. This pilot study investigated the effect of non-surgical periodontal therapy on systemic levels of CRP, fibrinogen, and WBC counts in subjects with CHD or no CHD (NCHD). METHODS Twenty-seven angiographically defined patients with CHD and 18 subjects with NCHD aged >or=40 years were recruited for the study. Periodontal disease was measured through the clinical parameters bleeding on probing (BOP) and probing depth (PD). All subjects received non-surgical periodontal therapy that included oral hygiene instructions and subgingival scaling and root planing. Systemic levels of inflammatory markers (CRP, fibrinogen, and WBC counts) were measured prior to and 1 month after periodontal therapy. RESULTS Seventeen subjects with CHD and 11 subjects with NCHD completed the study. Subjects with CHD or NCHD experienced significant reductions in BOP (59% and 34%, respectively; P <0.05) and PD (41% and 35%, respectively; P <0.05), with non-significant intergroup differences (P >0.05). In all subjects, CRP, fibrinogen, and WBC counts were reduced significantly (21% to 40%) after periodontal therapy (P <0.05). CONCLUSIONS Periodontal treatment resulted in significant decreases in BOP and PD and lowered serum inflammatory markers in patients with CHD or NCHD. This may result in a decreased risk for CHD in the treated patients. These findings will allow pursuit of a large-scale randomized intervention trial in this population.

Abstract
Background In most previous studies the association between number of teeth and cardiovascular diseases has been found to be stronger among younger age groups than in older age groups, which indicates that age may modify the association between number of teeth and cardiovascular diseases. We investigated the association between tooth loss and atherosclerotic vascular diseases such as myocardial infarction and stroke in a homogeneous elderly population. The study population was comprised of a subpopulation of 392 community-living elderly people who participated in the population-based Kuopio 75+ study. The data were collected through an interview, a structured clinical health examination and from patient records. The main outcome measures were a history of diagnosed myocardial infarction and diagnosed ischemic stroke. Prevalence proportion ratios (PPR) were estimated using generalised linear models. Results Edentate subjects had a weakly, statistically non-significantly increased likelihood of a history of myocardial infarction and ischemic stroke compared with dentate subjects. Those with a large number of teeth had a slightly, but not statistically significantly increased likelihood of a history of myocardial infarction and ischemic stroke compared with those with a small number of teeth. Conclusion These data did not show evidence that total or partial tooth loss would be associated with atherosclerotic vascular diseases such as myocardial infarction and ischemic stroke among an elderly population aged 75 years or older.

Abstract
INTRODUCTION Chronic infection and inflammation are considered to be risk factors in the development of cardiovascular diseases; the chronic inflammatory and microbial burden caused by the dental plaque in these individuals may predispose them to atherosclerotic process. AIMS The aims were to study the involvement of a high level of dental plaque, severe gingival inflammation and periodontitis in the development of early atherosclerotic process in women. METHODS Forty-six randomly chosen women with periodontitis and 21 periodontally healthy women were subjected to a comprehensive clinical oral examination, including oral hygiene status and level of gingival inflammation. Atherosclerotic risk factor analysis and carotid ultrasonography were performed. Common carotid artery intima-media thickness (IMT) and lumen diameter were measured and intima-media area (cIMA) was calculated. The following statistical methods were used: analysis of variance, chi-squared tests and multiple logistic regression analysis. RESULTS There were highly significant differences between the patients and controls in the amount of dental plaque, gingival inflammation as well as bleeding on probing and pocket depth. The mean values of IMT and cIMA were significantly higher in women with periodontal disease than in controls. Multiple logistic regression analysis identified periodontitis as a principal-independent predictor of both the common carotid artery cIMA and IMT. CONCLUSIONS The present results indicate that a high amount of dental plaque, severe gingival inflammation as well as periodontitis seem to be associated with the development of atherosclerotic lesions in women already at its early and subclinical stages.

Abstract
BACKGROUND Several epidemiological studies have demonstrated an association between periodontal disease and coronary heart disease (CHD). The association could be a result of confounding by mutual risk factors. The present study was undertaken in a Danish population to reveal the significance of common risk factors. METHODS The investigation was conducted as a case-control study comprising 250 individuals: 110 individuals with verified CHD from a Department of Cardiovascular Medicine and 140 control individuals without CHD from the Copenhagen City Heart Study. Information on diabetic status, smoking habits, alcohol consumption, physical activity, school attendance, household income, body weight and height, triglyceride, and serum cholesterol was obtained. Full-mouth probing depth (PD), clinical attachment loss (CAL), bleeding on probing (BOP), and alveolar bone level (ABL) on radiographs were registered. ABL was stratified into ABL1=ABL<or=2 mm; ABL2=ABL>2 to <or=4 mm; and ABL3=ABL>4 mm. Multiple logistic regression models with stepwise backward elimination were used allowing variables with P<0.15 to enter the multivariate analysis. RESULTS The CHD group had a significantly lower outcome with respect to PD, BOP, CAL, and ABL. For participants<60 years old, only risk factors such as smoking and diabetic status entered the multivariate analysis. For the ABL3 group, there was a significant association with CHD for participants<60 years old, the odds ratio being 6.6 (1.69 to 25.6). For participants>or=60 years old, there was no association. CONCLUSIONS The present study showed a positive association between periodontal disease and CHD in agreement with several other studies. The association was highly age dependent and could only be attributed to diabetes and smoking to some extent.

Abstract
BACKGROUND We performed a pilot study of a new method to identify the volatile organic compounds (VOCs) in breath associated with oral malodor, using gas chromatography and mass spectroscopy (GC/MS). METHODS Oral cavity breath was collected from seven patients with oral malodor. Breath samples (150 ml) were concentrated onto sorbent traps and analyzed by GC/MS. RESULTS Organoleptic scores ranged from 3.0 to 4.0 (mean = 3.3) on a scale of 0-5. Twenty-four of 30 (80.0%) of the most abundant oral malodor volatile organic compounds (OMVOCs) were alkanes and methylated alkanes. These VOCs are products of oxidative stress, generated by lipid peroxidation of polyunsaturated fatty acids in cell membranes. CONCLUSIONS Increased oxidative stress in the oral cavity of patients with oral malodor may account for the increased risk of atherosclerosis, coronary heart disease and stroke associated with periodontal disease. The breath test for OMVOCs could potentially provide an objective new test for the assessment of oral malodor.

Abstract
OBJECTIVE The present study was designed to determine, in a case-control study of a Spanish population, whether periodontitis is a risk factor for acute myocardial infarction. BACKGROUND Although part of cardiovascular risk could be explained by periodontal disease, available meta-analyses find significant heterogeneity and recommend the need for further observational and intervention studies. METHODS A case-control study was conducted of 149 Spanish patients aged between 40 and 75 years, with 72 cases (acute myocardial infarction) and 77 controls (trauma patients). Periodontitis was measured as the percentage of sites with clinical attachment loss greater than 3 mm. A multivariate logistic regression model was constructed to estimate the adjusted effect of periodontitis on acute myocardial infarction, after considering the potential confounding effect of a large pool of risk factors. RESULTS In a bivariate analysis, males, older patients, smokers, and those with hypertension, diabetes or hypercholesterolemia, showed an increased risk of acute myocardial infarction. The cases, compared to controls, showed worse results for all periodontal variables studied: gingival retraction, pocket depth, and periodontitis. The final multiple logistic model included sex, age, tobacco habit, hypertension, diabetes, hypercholesterolemia, regular exercise, and periodontitis. The association between periodontitis (dichotomized) and acute myocardial infarction was high and significant in both the unadjusted (odds ratio = 4.42, p < 0.001) and adjusted analyses (odds ratio = 3.31, p = 0.005). CONCLUSION There is evidence of an association between periodontitis and acute myocardial infarction after adjusting for well-known risk factors for acute myocardial infarction.

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 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
BACKGROUND Recent studies implicate exposure to systemic conditions involving chronic inflammation, including chronic periodontitis, in the etiology of atherosclerosis. RATIONALE A systematic review of the literature was conducted to assess the association between chronic inflammatory periodontal disease and atherosclerosis. FOCUSED QUESTION Does periodontal disease influence the initiation/progression of atherosclerosis and, therefore, cardiovascular disease (CVD), stroke, and peripheral vascular disease (PVD)? SEARCH PROTOCOL MEDLINE, pre-MEDLINE, MEDLINE Daily Update, and the Cochrane Controlled Trials Register were searched to identify human studies that related variables associated with atherosclerosis to periodontal disease. Searches were made for papers published from 1966 through March 2002. INCLUSION CRITERIA Published randomized controlled clinical trials (RCTs), longitudinal, cohort, and case-control studies were included. Study participants included those with atherosclerosis, myocardial infarction (MI), stroke, or PVD. Oral conditions included periodontal disease. EXCLUSION CRITERIA Only studies on humans were included. DATA COLLECTION AND ANALYSIS Because the studies used different oral assessment measures, it was not possible to perform a meta-analysis of the data reported. Weighted mean differences, relative risks, or odds ratios were compared for cohort studies. MAIN RESULTS 1. Of the initial 1,526 studies identified, 31 (including 8 case-control and 18 cross-sectional reports) were included in the analysis. Taken together, most of the literature supports a modest association between periodontal disease and atherosclerosis. However, data reported in several studies do not show this association. 2. The absence of a standard definition and measures for periodontal disease complicates interpretation of results, as do potential confounding risk factors common to both conditions. REVIEWERS' CONCLUSIONS 1. Periodontal disease may be modestly associated with atherosclerosis, MI, and CVD. 2. Additional large-scale longitudinal epidemiologic and intervention studies are necessary to validate this association and to determine causality.

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.
