Abstract
OBJECTIVES Periodontitis is a multifactorial disease that affects approximately 11% of the global population. The objective of this study was to examine whether, among individuals with phenylketonuria and type 1 diabetes mellitus, those with the IL1B rs1143634 and/or DEFB1 rs11362 genetic variants exhibit a higher periodontitis risk compared to healthy controls. MATERIALS AND METHODS In all, 43 phenylketonuria patients (aged 12-53), 28 type 1 diabetes mellitus patients (aged 11-40), and 63 healthy controls (aged 12-53) were included. The evaluation of periodontitis risk was conducted using the Silness-Löe plaque index, the Greene-Vermillion index, and an assessment for the necessity of calculus removal. Genetic variants rs1143634 and rs11362 were genotyped from salivary samples using restriction length polymorphism analysis. RESULTS The DEFB1 rs11362 variant was associated with higher Silness-Löe and Greene-Vermillion index scores in phenylketonuria patients (p = 0.011 and p = 0.043, respectively). The IL1B rs1143634 variant was associated with lower calculus removal necessity in type 1 diabetes mellitus patients (p = 0.030). Clinical examination showed the worst oral hygiene index scores for PKU patients. PKU patients also reported the least consistent tooth brushing and flossing habits. CONCLUSIONS Genetic associations between DEFB1 rs11362 and IL1B rs1143634 variants and oral hygiene indices were observed in the PKU and T1DM groups, suggesting that genetic factors may contribute to periodontal health differences in these populations. Further research with a larger sample size is needed to confirm these findings and develop targeted oral health interventions.

BMC Med 2023; 21:430.

Abstract
BACKGROUND Recent studies have highlighted the role of low-grade systemic inflammation in linking periodontitis to cardiovascular disease (CVD) outcomes, but many aspects remain unclear. This study examines the independent and reciprocal associations of periodontitis and low-grade systemic inflammation with all-cause and CVD mortality in a large-scale cohort. METHODS A total of 3047 participants from the prospective, population-based Study of Health in Pomerania (SHIP-START) were followed for a period of 13.0 ± 2.4 years. For the association between various inflammation/periodontitis measures and mortality, hazard ratios (HRs) were obtained from covariate-adjusted Cox proportional hazards models. Interactions were analysed in joint models: on the multiplicative scale, HRs were reported and on the additive scale, relative excess risks due to interaction (RERI) were calculated. Subject and variable-specific interval records were used to account for time-varying exposures and covariates. RESULTS During the observation period, 380 (12.5%) individuals died from CVD (n = 125) or other causes (n = 255). All markers of periodontitis and inflammation showed apparent associations with all-cause mortality (HRs per SD-increase: mean PPD: 1.068 (95% confidence interval (CI): 0.988-1.155), mean CAL: 1.205 (95% CI: 1.097-1.323), missing teeth: 1.180 (95% CI: 1.065-1.307), periodontitis score: 1.394 (95% CI: 1.202-1.616), leukocytes: 1.264 (95% CI: 1.163-1.374), fibrinogen: 1.120 (95% CI: 1.030-1.218), CRP: 1.231 (95% CI: 1.109-1.366), inflammation score: 1.358 (95% CI: 1.210-1.523)). For CVD mortality, all PPD related variables showed significant associations. Interaction modelling revealed some variation with respect to mortality type and exposure combinations. On the additive scale, RERIs for periodontitis score and inflammation score implied 18.9% and 27.8% excess mortality risk for all-cause and CVD mortality, respectively. On the multiplicative scale, the HRs for interaction were marginal. CONCLUSIONS Both periodontitis and inflammation were significantly associated with all-cause mortality and CVD mortality. On the additive scale, a substantial excess risk was observed due to the interaction of periodontitis and inflammation, suggesting that the greatest treatment benefit may be achieved in patients with both periodontitis and high systemic inflammation. As periodontal therapy has been reported to also reduce systemic inflammation, the possibility of a reduction in CVD mortality risk by anti-inflammatory treatments, including periodontal interventions, seems worthy of further investigation.

Abstract
Cardiovascular disease has serious economic and social consequences that affect people, health systems and societies around the world. Ischemic heart disease is one of the main global causes of death of the population, and its growth is predicted in the coming years. This fact continues to be of serious concern to health, social and economic services. Cardiovascular disease remains the most common cause of death, and age-standardized rates are higher for men than for women. Cardiovascular comorbidity increases significantly with age.The combination of ischemic heart disease and comorbid pathology is noted in cancer incidence, bronchial asthma, non-alcoholic fatty liver disease, type 2 diabetes mellitus, chronic obstructive pulmonary disease, periodontal disease, etc. It is necessary to analyze the existing disease with past diseases, risk factors and predictors available in the patient. The presence of concomitant diseases quite often requires additional diagnostic methods and changes in the tactics of treating coronary heart disease due to the fact that some of them are a contraindication to the use of certain groups of drugs. Periodontal disease includes a wide range of inflammatory conditions that affect the supporting structures of the teeth, which can lead to tooth loss and contribute to systemic inflammation. Periodontal disease is associated with several systemic diseases, one of which is coronary artery disease. It is imperative that clinicians understand the link between periodontal disease and cardiovascular disease. Comprehensive treatment of periodontitis and restoration of a healthy periodontium can help reduce overall inflammation in the body and reduce the risks of coronary heart disease.

Abstract
AIM Studies have found that periodontal disease and tooth loss are associated with increased mortality; however, associations with cause-specific mortality and all-cause mortality within specific subgroups have not been thoroughly investigated. MATERIALS AND METHODS We examined the association of self-reported periodontal disease and disease/decay-related tooth loss with subsequent all-cause and cause-specific mortality in the Sister Study, a prospective cohort study of 50,884 women aged 35-74 years at baseline, whose sister was diagnosed with breast cancer. Hazard ratios (HRs) and 95% confidence intervals (95% CIs) for the associations were calculated with adjustment for relevant confounders. RESULTS With a mean follow-up of 10.9 years (range 0.1-14.3), 2058 women died. Participants with periodontal disease had a slightly higher rate of all-cause mortality (HR = 1.08, 95% CI 0.98-1.19), while participants with tooth loss had an increased rate of all-cause mortality (HR = 1.15, 95% CI 1.05-1.26). For cause-specific mortality, women with tooth loss had increased rates of death from circulatory system diseases, respiratory system diseases, and endocrine/metabolic diseases. Results varied in stratified models, but no heterogeneity across strata was found. CONCLUSIONS In this large prospective study, periodontal disease and tooth loss were associated with all-cause and certain specific cause-specific mortality outcomes.

Abstract
OBJECTIVE Frailty is the physiological stress that individuals suffer during their life. In past populations, frailty is conventionally assessed through the occurrence of different biomarkers of biological stress. Some efforts have been made to propose indexes that combine all biomarkers. However, these indices have some critical limitations: they cannot be used on incomplete skeletons, do not consider the severity and/or healing of lesions, and assign equal importance to different biomarkers. To address these limitations, we propose a new index to assess frailty in skeletal individuals. MATERIAL AND METHODS By statistically analyzing a large amount of osteological data available from the Museum of London, and using a Logit model, we were able to define a different weight for each reported biomarker of frailty, based on their importance in increasing the risk of premature death for the individuals. RESULTS The biological index of frailty (BIF) is the weighted mean of all biomarkers scored on the individuals, according to a different degree of importance assigned to each one. It also considers the severity and healing of the biomarkers when this is relevant to diagnose frailty. We applied BIF on a sample of Monastics and Non-Monastics from medieval England and compared it with the skeletal index of frailty (SFI). DISCUSSION BIF is the first frailty index that gives a different weight to each skeletal biomarker of stress, considers both severity and healing of the lesions, and can be applied on partial skeletal remains. The comparison with SFI showed that BIF is applicable to a larger number of skeletal individuals, revealing new differences between the Monastic and the Non-Monastic groups.

Abstract
Tooth loss reflects the endpoint of two major dental diseases: dental caries and periodontitis. These comprise 2% of the global burden of human diseases. A lower number of teeth has been associated with various systemic diseases, in particular, atherosclerotic cardiovascular diseases (ACVD). The aim was to summarize the evidence of tooth loss related to the risk for ACVD or death. Cohort studies with prospective follow-up data were retrieved from Medline-PubMed and EMBASE. Following the PRISMA guidelines, two reviewers independently selected articles, assessed the risk of bias, and extracted data on the number of teeth (tooth loss; exposure) and ACVD-related events and all-cause mortality (ACM) (outcome). A total of 75 articles were included of which 44 were qualified for meta-analysis. A lower number of teeth was related to a higher outcome risk; the pooled risk ratio (RR) for the cumulative incidence of ACVD ranged from 1.69 to 2.93, and for the cumulative incidence of ACM, the RR ranged from 1.76 to 2.27. The pooled multiple adjusted hazard ratio (HR) for the incidence density of ACVD ranged from 1.02 to 1.21, and for the incidence density of ACM, the HR ranged from 1.02 to 1.30. This systematic review and meta-analyses of survival data show that a lower number of teeth is a risk factor for both ACVD and death. Health care professionals should use this information to inform their patients and increase awareness on the importance of good dental health and increase efforts to prevent tooth loss.

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

Abstract
Atherosclerotic cardiovascular disease (ACVD) is an inflammatory disease of the coronary arteries associated with atheroma formation, which can cause disability and often death. Periodontitis is ranked as the sixth most prevalent disease affecting humans affecting 740 million people worldwide. In the last few decades, researchers have focused on the effect of periodontal disease (PD) on cardiovascular disease. The aim of this review was to investigate the association between these two diseases. PD is a potential risk factor that may initiate the development, maturation, and instability of atheroma in the arteries. Two mechanisms were proposed to explain such association, either periodontal pathogens directly invade bloodstream or indirectly by increasing systemic level of inflammatory mediators. Interestingly, it has been suggested that improvement in the condition of one disease positively impact the condition of the other one. Highlighting the association between these two diseases, the importance of early diagnosis and treatment of PD and its impact on cardiovascular status may be of great value in reducing the complications associated with ACVDs. Further in vitro and in vivo studies with longer follow up are necessary to confirm the causal relationship between PD and ACVDs.

Biosci Rep 2019; 39:BSR20181773. [PMID: 30530864 PMCID: PMC6328868 DOI: 10.1042/bsr20181773] [Citation(s) in RCA: 46] [Impact Index Per Article: 9.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2018] [Revised: 11/12/2018] [Accepted: 11/26/2018] [Indexed: 12/20/2022] Open
Abstract
Background: The association of tooth loss with mortality from all causes, cardiovascular diseases (CVD), and coronary heart disease (CHD) has been studied for many years; however, the results are inconsistent. Method: PubMed, Embase, Web of Knowledge, and Cochrane Oral Health Group’s Trials Register databases were searched for papers published from 1966 to August 2018. We conducted dose–response meta-analysis to quantitatively evaluate the relation between tooth loss and risk of mortality from all causes, CVD, and CHD. Results: In the present study, 18 prospective studies conducted until August 2018 were considered eligible for analysis. In the analysis of linear association, the summarized relative risk (RR) values for each 10-, 20-, and 32-tooth loss for all-cause mortality were 1.15 (1.11–1.19), 1.33 (1.23–1.29), and 1.57 (1.39–1.51), respectively. Subgroup and sensitivity analyses showed consistent results. A linear relationship was found among all-cause mortality, with Pnonlinearity = 0.306. The susceptibility to all-cause mortality increased by almost 1.48 times at very high tooth loss (28–32), and slight flattening of the curve was noted. However, the summarized RR values for increment for 10-, 20-, and 32-tooth loss were not or were marginally related to increased risk of mortality from CVD/CHD. Subgroup and sensitivity analyses revealed inconsistent results. Tooth loss showed linear association with CHD mortality but not with CVD mortality. The susceptibility to all-cause mortality increased by almost 1.48 and 1.70 times for CVD and CHD, respectively, at very high tooth loss (28–32). The curve exhibited slight flattening; however, no statistical significance was detected. Conclusion: In the meta-analysis, our findings confirmed the positive relationship between tooth loss and susceptibility to all-cause mortality, but not for circulatory mortality. However, the finding that tooth loss might play a harmful role in the development of all-cause mortality remains inconclusive. Tooth loss may be a potential risk marker for all-cause mortality: however, their association must be further validated through large prospective studies.

Abstract
BACKGROUND Periodontal disease is a risk factor for atherosclerotic cardiovascular disease and it is recommended internationally that patients with cardiovascular disease should engage in preventative oral health practices and attend regular dental care visits. This study aimed to explore the oral health status, behaviours and knowledge of patients with cardiovascular disease. METHODS A cross-sectional questionnaire containing 31 items was administered to patients with cardiovascular disease from cardiac rehabilitation and outpatient clinics in Sydney Australia in 2016-2017. RESULTS Of the 318 patients surveyed, 81.1% reported having at least one oral health problem. Over a third (41.2%) of participants had not seen a dentist in the preceding 12 months and 10.7% had received any oral healthcare information in the cardiac setting. Those with valvular conditions were more likely to have received information compared to those with other cardiovascular conditions (40.6% versus 7.4%, p < 0.001). Only half of the participants had adequate oral health knowledge. CONCLUSIONS Despite a high incidence of reported oral health problems, many patients lacked knowledge about oral health, were not receiving oral health information from cardiac care providers and had difficulty accessing dental services. Further research is needed to develop oral health strategies in this area.

Aging Clin Exp Res 2018; 30:581-588. [PMID: 28856592 DOI: 10.1007/s40520-017-0811-y] [Citation(s) in RCA: 27] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/18/2017] [Accepted: 07/31/2017] [Indexed: 12/17/2022]
Abstract
AIM The objective of this controlled clinical study was to evaluate the association between oral health and 1-year mortality among nursing home residents with or without oral health intervention. METHODS This research was part of a multidisciplinary intervention study (EVI-P) performed in 14 nursing homes in Germany. Two-hundred and nineteen nursing home residents were included in the study and assigned to an intervention group, for which dental health education was offered and ultrasonic baths were used for denture cleaning (n = 144), or to a control group (n = 75). Before the intervention, each participant was examined, and dental status, plaque control record (PCR), Denture Hygiene Index, and results from the Revised Oral Assessment Guide were recorded. Amount of care needed and dementia were also assessed, by use of the Barthel Index and the Mini Mental State Examination, respectively. Participant mortality was determined after 12 months, and bivariate analysis and logistic regression models were used to evaluate possible factors affecting mortality. RESULTS Bivariate analysis detected a direct association between greater mortality and being in the control group (p = .038). Participants with higher PCR were also more likely to die during the study period (p = .049). For dentate participants, the protective effect of being in the intervention group was confirmed by multivariate analysis in which covariates such as age and gender were considered. CONCLUSION Oral hygiene and oral health seem to affect the risk of mortality of nursing home residents. Dental intervention programs seem to reduce the risk of 1-year mortality among nursing home residents having remaining natural teeth. Further studies, with larger sample sizes and evaluation of the causes of death, are necessary to investigate the reasons for these associations.

Abstract
OBJECTIVE To study the association between oral health and all-cause mortality rate over 44 years. In addition, the specific relations between oral health and death caused by cardiovascular disease (CVD), cancer or other reasons were investigated. MATERIALS AND METHODS An epidemiological investigation studying the oral health of the population consisting of 1393 randomly selected subjects was performed in the County of Stockholm. The individuals were invited to a clinical examination, an interview and a radiographic examination. The incidence of mortality during the years 1970-2014 as well as the causes of death according to the death certificate were registered in 2015. Cox regression survival analysis was used for investigating the effect of several variables upon the time to the outcome of death. RESULTS Forty-six percent of the subjects were still alive at the end of the year 2014. Cancers caused 27% of the deaths, while 22% died due to CVD. The mortality risk was positively and significantly correlated to oral health when compensated for age, sex, smoking and social status. In addition, the mortality risk caused by CVD, cancer or other reasons was significantly increased for those with poor oral health. CONCLUSIONS Oral health was found to be a risk indicator of death caused by CVD and cancer as well as for all-cause mortality. Thus, the associations are unspecific. Harmful lifestyle factors impact dental health behavior as well as mortality risk. This might contribute to the association between oral health and mortality risk.

Abstract
OBJECTIVES This study aims to assess mortality risk and its association to health aspects in dentate individuals 60 years of age and older. MATERIALS AND METHODS Medical and periodontal data from 870 dentate individuals (age range 60–96) participating in the Swedish National Study on Aging and Care in Blekinge (SNACBlekinge)with survival statistics over 6 years were studied. RESULTS During 6 years of follow-up, 42/474 of the individuals(8.9 %), who at baseline were between age 60 and 75, and 134/396 individuals of the individuals (33.9 %), who at baseline were ≥75 years, died. Surviving dentate individuals had more teeth (mean 19.3, S.D.±7.9) than those who died (mean 15.9,S.D.±7.3; mean diff 3,3; S.E. mean diff 0.7; 95 % CI 2.0, 4.6;p=0.001). A self-reported history of high blood pressure (F=15.0, p<0.001), heart failure (F=24.5, p<0.001, observed power=0.99), older age (F=34.7, p<0.001), male gender(F=6.3, p<0.01), serum HbA1c with 6.5 % as cutoff level(F=9.3, p=0.002) were factors associated with mortality. A medical diagnosis of heart disease, diabetes, any form of cancer,or periodontitis failed to predict mortality. CONCLUSIONS A self-reported history of angina pectoris, chronic heart failure, elevated serum HbA1c, and few remaining teeth were associated with mortality risk. A professional diagnosis of cardiovascular disease, diabetes, cancer, or periodontitis was not predictive of mortality. CLINICAL RELEVANCE Self-health reports are important to observe in the assessment of disease and survival in older individual.

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
AIM Periodontal diseases are associated with systemic health and health behaviors; the purpose of this study was to investigate periodontal health status and its association with systemic health and health behaviors in the elderly. MATERIALS AND METHODS Data was collected from 300 random Case Western Reserve University (CWRU) dental school patient charts, aged 65 or higher. A modified WHO form was used to collect the date on: periodontal conditions using the community periodontal index (CPI), demographics, systemic health and certain health behaviors. Community periodontal index collected data for six sextants. Descriptive tests and bivariate analytic tests, Chi-square test and computation of odds ratio, investigated any association between certain periodontal conditions and demographic as well as systemic health attributes. RESULTS In the study cohort, the average age was 73.7 ± 6.8 years. Moderate periodontitis (38.9%) was the most prevalent periodontal health condition, while severe periodontitis was the least prevalent periodontal health (6.1%). Nearly 30% of the cohort had healthy periodontium. Only insurance status was associated with healthy periodontium (p < 0.05). CONCLUSION Moderate periodontitis was the most prevalent among the studied subjects. A positive association was found with the insurance status of the subjects and the healthy periodontium. No association was found between periodontal disease and smoking, alcohol consumption, diabetes and cardiovascular disease.

Abstract
BACKGROUND Oral infection contributes to atherosclerosis and coronary heart disease. We hypothesized that dental caries may be associated with out-of-hospital cardiac arrests (OHCA) of cardiac origin, but not non-cardiac origin. METHODS AND RESULTS We compared the age-adjusted incidence of OHCA (785,591 cases of OHCA: 55.4% of cardiac origin and 44.6% of non-cardiac origin) to the age-adjusted prevalence of dental caries between 2005 and 2011 in the 47 prefectures of Japan. In both the total population and males over 65 years, the number of cases of dental caries was significantly associated with the number of OHCA of total and cardiac origin from 2005 to 2011, but not those of non-cardiac origin. In the total population, the age-adjusted prevalence of dental caries was not significantly associated with the age-adjusted incidence of OHCA (total OHCA: r correlation coefficient=0.22, p=0.14; OHCA of cardiac origin: r=0.25, p=0.09; OHCA of non-cardiac origin: r=-0.002, p=0.99). Among male patients over 65 years, the age-adjusted prevalence of dental caries was significantly associated with OHCA of total and cardiac origin, but not non-cardiac origin (total OHCA: r=0.47, p<0.001; OHCA of cardiac origin: r=0.37, p=0.01; OHCA of non-cardiac origin: r=0.28, p=0.054). CONCLUSIONS While oral hygiene is important in all age groups, it may be particularly associated with OHCAs of cardiac origin in males over 65 years.

Abstract
OBJECTIVES The aim of this study was to investigate if a minimally invasive oral health package with the use of atraumatic restorative treatment (ART) or a conventional restorative technique (CT) would result in any perceived benefit from the patients' perspective and if there would be any difference between the two treatment groups. MATERIALS AND METHODS In this randomised clinical trial, 99 independently living older adults (65-90 years) with carious lesions were randomly allocated to receive either ART or conventional restorations using minimally invasive/intervention dentistry (MID) principles. Patients completed an Oral Health Impact Profile (OHIP)-14 questionnaire before and 2 months after treatment. They were also asked to complete a global transition question about their oral health after treatment. RESULTS At baseline, the mean OHIP-14 scores recorded were 7.34 (ART) and 7.44 (CT). Two months after treatment intervention, 90 patients answered the OHIP-14 and the mean scores were 7.23 (not significant (n.s.)) and 10.38 (n.s.) for the ART and CT groups, respectively. Overall, 75.5 % of patients stated that their oral health was better compared to the beginning of treatment. CONCLUSIONS Although not shown by the OHIP-14, patients perceived an improvement in their overall oral status after treatment, as demonstrated by the global transition ratings in both groups. CLINICAL RELEVANCE Dental treatment using minimally invasive techniques might be a good alternative to treat older individuals, and it can improve their oral health both objectively and subjectively.

Abstract
Periodontitis and cardiovascular disease have a complex etiology and genetics and share some common risk factors (i.e., smoking, age, diabetes, etc.). In recent years, the relationship between periodontal disease and cardiovascular disease has been investigated extensively. This research mostly focused on the fact that periodontitis is an independent risk factor for cardiovascular disease. Our aim in this article is to investigate the etiological relationship between periodontal disease and cardiovascular disease and the mechanisms involved in this association. According to the current literature, it is concluded that there is a strong relationship between these chronic disorders.

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.

The association of tooth loss with all-cause and circulatory mortality. Is there a benefit of replaced teeth? A systematic review and meta-analysis. Clin Oral Investig 2011; 16:333-51.

Abstract
We systematically reviewed whether the number of teeth is related to all-cause or circulatory mortality and whether replaced teeth are protective against all-cause or circulatory mortality. The search was based on the PubMed database. All cohort studies published in peer-reviewed journals were selected. Studies on periodontal disease and mortality were excluded if they did not provide information on the number of teeth. Risk estimates from studies with appropriate exposure definition, confounder adjustment and sample size were included in a meta-analysis. Three high-quality studies found a relationship between the number of teeth and circulatory mortality, whereas a moderate study did not. Two out of four moderate- to high-quality studies reported a relationship between the number of teeth and all-cause mortality. No study has investigated whether replaced teeth are protective against mortality. Therefore, denture use was taken as proxy. The methodological quality of studies on denture use and mortality was generally low to moderate. The findings of two moderate studies indicated an effect of prosthodontic replacements on all-cause mortality, which was supported in bias analysis. It is open whether competing risks of cause-specific death other than circulatory mortality reduce an effect of the number of teeth on all-cause mortality. An effect of denture use on circulatory mortality remains to be established, as well as whether the number of replaced teeth affects mortality. Specifying the role of potential pathways by which tooth loss-related mortality is mediated will possibly increase the value of dental treatment for general health.

Abstract
It is now well accepted that besides the cholesterol associated mechanisms of atherogenesis, inflammation plays a crucial role in all stages of the development of the atherosclerotic lesion. This 'inflammation hypothesis' raises the possibility that through systemic elevations of pro-inflammatory cytokines, periodontal diseases might also contribute to systemic inflammation and, therefore, to atherogenesis. In fact, there is evidence that periodontal diseases are associated with higher systemic levels of high-sensitivity C-reactive protein and a low grade systemic inflammation. This phenomenon has been explained based on mechanisms associated with either the infectious or the inflammatory nature of periodontal diseases. The purposes of this article were to review (1) the evidence suggesting a role for oral bacterial species, particularly periodontal pathogens, in atherogenesis; (2) the potential mechanisms explaining an etiological role for oral bacteria in atherosclerosis; (3) the evidence suggesting that periodontal infections are accompanied by a heightened state of systemic inflammation; (4) the potential sources of systemic inflammatory biomarkers associated with periodontal diseases; and (5) the effects of periodontal therapy on systemic inflammatory biomarkers and cardiovascular risk.

Abstract
In the last decade the effect of oral health on the general health and mortality of elderly people has attracted attention. We explored the association of dental health behaviors and dentition on all-cause mortality in 5611 older adults followed from 1992 to 2009 (median = 9 years) and calculated risk estimates using Cox regression analysis in men and women separately. Toothbrushing at night before bed, using dental floss everyday, and visiting the dentist were significant risk factors for longevity. Never brushing at night increased risk 20-35% compared with brushing everyday. Never flossing increased risk 30% compared with flossing everyday. Not seeing a dentist within the last 12 months increased risk 30-50% compared with seeing a dentist two or more times. Mortality also increased with increasing number of missing teeth. Edentulous individuals (even with dentures) had a 30% higher risk of death compared with those with 20+ teeth. Oral health behaviors help maintain natural, healthy and functional teeth but also appear to promote survival in older adults.

Abstract
Serum lipid and inflammatory cytokine profiles were assessed in 124 in-patients with coronary heart disease (CHD) (CHD group) and 43 inpatients with no evidence of CHD (control group). In all patients, research questionnaires and examinations of periodontal health were conducted and venous blood samples were analysed. Both groups were divided into two subgroups according to the presence or absence of chronic periodontitis in individual patients. The prevalence of chronic periodontitis was higher in patients from the CHD group than in the control group. Levels of total cholesterol, triglycerides, low-density lipoprotein, oxidized low-density lipoprotein, high-sensitivity C-reactive protein, interleukin-6 and tumour necrosis factor-a were significantly higher in CHD patients with chronic periodontitis than in those without periodontitis. In conclusion, chronic periodontitis may be associated with CHD.

Abstract
Oral health has been implicated in systemic disease throughout the ages; however, the understanding of the relationship between oral disease and systemic diseases such as cardiovascular disease and Type 2 diabetes mellitus is still emerging today. Chronic periodontal disease is widespread in the general population and a significant proportion of adults suffer from the most severe form of the disease. Dental plaque biofilm is necessary for the development of chronic periodontal disease with genetic and environmental factors contributing towards the pathogenesis. The putative biological mechanisms of the association between oral disease and atherogenesis are discussed, although there is insufficient evidence to establish causality at this time. Regardless of a direct causal relationship between oral disease and cardiovascular disease, treatment of oral disease leads to both a reduction in the systemic inflammatory burden as reflected in inflammatory markers and an improvement in endothelial function and hence improved overall health outcomes. A brief overview of periodontal disease including etiology, pathogenesis, screening and therapeutic implications is presented.

Abstract
OBJECTIVE To assess the association between the periodontal health status and level of education over a 5-year period among the elderly aged 75 years and older. BACKGROUND Oral health among the higher educated is known to be better than among the less-well educated. On the other hand, the prevalence and severity of periodontal disease has been found to grow with increasing age. METHODS The participants were derived from a population-based Helsinki Aging Study, a random sample of 76-, 81- and 86-year-old elderly. The 170 dentate elderly who underwent clinical oral examinations at baseline and 71 who participated in the follow-up were included in this study. The data was collected from intraoral and radiological examinations and from a structured questionnaire. RESULTS Subjects with a higher level of education had more retained teeth than subjects with a lower level of education. According to CPITN index, better-educated participants had more healthy sextants, but they also had more sextants with periodontal pockets. Radiographic examination showed similar results. CONCLUSION Level of education has a clear effect on the periodontal health status in the elderly. More treatment need seems to polarise into those elderly who are better educated as they retain more teeth into old age.

Abstract
Cardiovascular disease (CVD) and type 2 diabetes are common systemic illnesses with reliable, predictive risk factors. CVD is the number one killer worldwide accounting for nearly 30% of deaths and type 2 diabetes has reached epidemic proportions in many western industrialized countries. Both of these illnesses can go undiagnosed in an alarming number of people for significant periods of time. The relationship between oral health and systemic health has become the focus of much discussion and research in recent times. It is now widely accepted that periodontal disease is associated with systemic illnesses such as CVD and type 2 diabetes. Cigarette smoking and obesity are major risk factors accounting for a large portion of the global disease burden. Many periodontal patients may be at risk of systemic conditions but be asymptomatic and undiagnosed. With an aging population who are mostly retaining their natural dentition, the need for periodontal management will continue to rise in the future. Dental professionals are well placed to perform general health screening for their patients. Therefore, risk assessment during the periodontal examination may facilitate the early identification of the large proportion of people who are unaware of their risk status. As identification and intervention of patients with increased risk factors is key to lowering the systemic disease burden, general health screening during periodontal examinations may present an important opportunity for many patients.

Abstract
BACKGROUND The relationship between periodontitis and outcomes in patients treated with long-term hemodialysis is controversial. Our previous work suggests that periodontitis is associated with malnutrition and inflammation. Here, we hypothesize that periodontitis is associated with mortality in hemodialysis patients. STUDY DESIGN Prospective observational study. SETTING & PARTICIPANTS 253 patients undergoing hemodialysis at a single hospital-based dialysis facility. PREDICTOR Severity of periodontal disease (mild, moderate, or severe based on oral examination of 6 teeth). OUTCOMES & MEASUREMENTS All-cause and cardiovascular mortality during a 6-year follow-up after an oral health examination of index teeth. RESULTS During the 6-year follow-up, 102 patients died. Death occurred in 70.6%, 41.8%, and 24.0% of patients with severe, moderate, and mild/no periodontitis, respectively. Using mild/no periodontitis as the reference group and adjustment for demographic characteristics, comorbid conditions, and selected laboratory values, HRs for all-cause mortality were 1.39 (95% CI, 0.83-2.34) and 1.83 (95% CI, 1.04-3.24) for moderate and severe periodontitis, respectively. HRs for cardiovascular mortality were not statistically significant. LIMITATIONS Single assessment of periodontal disease severity. CONCLUSIONS For patients undergoing long-term hemodialysis, periodontitis is associated with increased risk of death. Clinical trials are required to determine whether treatment of periodontitis decreases mortality.

Abstract
BACKGROUND Periodontal disease is common among adults in the US and is a potential source of chronic inflammation. Recent data have suggested an important role for chronic inflammation in the development of coronary heart disease (CHD). OBJECTIVE To aid the United States Preventive Services Task Force (USPSTF) in evaluating whether periodontal disease is an independent novel risk factor for incident CHD. METHODS Studies were identified by searching Medline (1966 through March 2008) and reviewing prior systematic reviews, reference lists, and consulting experts. Prospective cohort studies that assessed periodontal disease, Framingham risk factors, and coronary heart disease incidence in the general adult population without known CHD were reviewed and quality rated using criteria developed by the USPSTF. Meta-analysis of good and fair quality studies was conducted to determine summary estimates of the risk of CHD events associated with various categories of periodontal disease. RESULTS We identified seven articles of good or fair quality from seven cohorts. Several studies found periodontal disease to be independently associated with increased risk of CHD. Summary relative risk estimates for different categories of periodontal disease (including periodontitis, tooth loss, gingivitis, and bone loss) ranged from 1.24 (95% CI 1.01-1.51) to 1.34 (95% CI 1.10-1.63). Risk estimates were similar in subgroup analyses by gender, outcome, study quality, and method of periodontal disease assessment. CONCLUSION Periodontal disease is a risk factor or marker for CHD that is independent of traditional CHD risk factors, including socioeconomic status. Further research in this important area of public health is warranted.

Abstract
BACKGROUND Recent meta-analyses reported a weak association between periodontal disease (PD) on clinical examination and cardiovascular disease (CVD). Systemic bacterial exposure from periodontitis, which correlates poorly with the clinical examination, has been proposed as the more biologically pertinent risk factor. The purpose of this study was to review and analyze the association between PD with elevated systemic bacterial exposure and CVD. METHODS We searched in the PubMed, Cochrane Controlled Trials Register, EMBASE, and SCOPUS databases for all literature examining PD and CVD. From 10 selected publications, we extracted 12 cohort (N = 5) and cross-sectional (N = 7) studies and included 11 of these in a meta-analysis. With stratified analyses, this resulted in 14 analyses of coronary heart disease (CHD; N = 7), stroke (N = 4), and carotid intima-medial thickening (CIMT; N = 3) as a measure of early atherosclerosis. Systemic bacterial exposure was measured by periodontal bacterial burden (N = 1), periodontitis-specific serology (N = 12), or C-reactive protein (N = 1). RESULTS Periodontal disease with elevated markers of systemic bacterial exposure was associated strongly with CHD compared to subjects without PD, with a summary odds ratio of 1.75 (95% confidence interval (CI): 1.32 to 2.34; P <0.001). This group was not associated with CVD events or with stroke but was associated with a significant increase in mean CIMT (0.03 mm; 95% CI: 0.02 to 0.04). CONCLUSION Periodontal disease with elevated bacterial exposure is associated with CHD events and early atherogenesis (CIMT), suggesting that the level of systemic bacterial exposure from periodontitis is the biologically pertinent exposure with regard to atherosclerotic risk.

Abstract
OBJECTIVE Although associations between number of teeth and mortality have been found in some studies, the results have not been conclusive. The aim of this study was to determine whether dental status at age 75 is an independent predictor of survival in three Nordic populations. MATERIAL AND METHODS The baseline study was conducted as part of a comparative Nordic investigation of systematic samples of 75-year-old men and women born in the period 1914-16 (n=1004) and living independently in three Nordic localities: Glostrup in Denmark, Jyväskylä in Finland, and Göteborg in Sweden. Performed in 1989-91, the study included a home interview, a health questionnaire, and a laboratory examination. For the present study, the mortality data of all participants up to age 82 were collected from official registers in 1999. RESULTS Lower mortality during 7 years was associated with higher number of remaining teeth at age 75. In Jyväskylä and Göteborg, but not in Glostrup, the association between number of teeth and mortality was statistically significant. For all three samples pooled and adjusted for sex and location, this association was significant (odds ratio 0.866; p<0.001). CONCLUSIONS Number of teeth is a significant predictor of 7-year mortality in 75-year-old women independently of a number of factors related to lifestyle, disease, and reduced functional capacity.

Abstract
Detrimental effects of oral infections on general health have been known for almost 3000 years. Modern studies, however, have cast new light on the pathogenic mechanisms by which oral infections appear to link with morbidity and mortality. In particular, among the elderly, poor dental health seems to associate with all-cause mortality. This review aims to provide an overview of present knowledge of these issues, starting from dental bacteraemia, oral mucosal infections and problems of drug resistance and, briefly, discussing what is known about the link between oral health and some systemic diseases such as atherosclerosis and type-2 diabetes. The main conclusions are that scientific evidence is still weak on these interactions and that the elderly should be better taken into account when planning future studies. Functions of the body differ in the frail and diseased from those of the young. Consequently, novel prevention and treatment strategies should be developed and properly tested for combating oral infections in elderly populations. Specific suggestions for further research are outlined.

Abstract
Accumulating evidence suggests that chronic infections, such as periodontitis, are associated with increased risk for cardiovascular diseases (CVD). The mechanisms behind the association are not known. Like herpes viruses and Chlamydia pneumoniae, periodontal pathogens cause atherosclerosis in experimental animals and have been found in human atherosclerotic lesions. Higher concentrations of total and low density lipoprotein (LDL) cholesterol and triglycerides and lower concentrations of high density lipoprotein (HDL) cholesterol have been observed in individuals with periodontitis before periodontal treatment. Periodontitis also induces a peripheral inflammatory and immune response, reflected in elevated concentrations of C-reactive protein (CRP) and IgA-class antibodies to periodontal pathogens. The prevalence of CVD seems to be highest in those individuals in whom periodontitis coexists with elevated CRP levels. This may indicate that periodontitis is a CVD risk factor in individuals who react to the infection with a systemic inflammatory and immune response. This may be due to genetic reasons and may also apply to other chronic low-grade infections.

Abstract
There have been 42 published studies describing associations between oral conditions and cardiovascular diseases. In the absence of randomized controlled trials, the 16 longitudinal studies represent the highest level of evidence available. However, two databases produced eight of the 16 studies. There also is extensive variability in definitions of the oral exposure that include salivary flow, reported periodontal disease, number of teeth, oral organisms, antibodies to oral organisms, Total Dental Index, Community Periodontal Index of Treatment Needs, plaque scores, probing depth, attachment loss, and bone level. Variability also exists in the cardiovascular outcomes that include atherosclerosis measures and events, such as hospitalization for coronary heart disease (CHD), chronic CHD, fatal CHD, total stroke, ischemic stroke, and revascularization procedures. One of the criticisms of this research is that the exposure has not been represented by measures of infection. To begin to address this concern, we present new data showing that patterns of high and low levels of eight periodontal pathogens and antibody levels against those organisms are related to clinical periodontal disease as well as other characteristics of the individuals, such as age, race, gender, diabetic status, atherosclerosis, and CHD. As others before us, we conclude that the cumulative evidence presented above supports, but does not prove, a causal association between periodontal infection and atherosclerotic cardiovascular disease or its sequelae. A number of legitimate concerns have arisen about the nature of the relationship and, indeed, the appropriate definitions for periodontal disease when it is thought to be an exposure for systemic diseases. There is still much work needed to identify which aspects of the exposure are related to which aspects of the outcome. Principal component analyses illustrate the complexity of the interactions among risk factors, exposures, and outcomes. These analyses provide an initial clustering that describes and suggests the presence of specific syndromes.
