[PMID: 34746932 PMCID: PMC8559319 DOI: 10.1016/j.ijcrp.2021.200110] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/26/2021] [Revised: 09/28/2021] [Accepted: 10/05/2021] [Indexed: 12/16/2022]
Abstract
Background Periodontitis is a chronic multifactorial inflammatory disease of the supportive tissues of the teeth. Pathophysiological evidence suggests a possible common inflammatory background between periodontitis and cardiovascular diseases (CVD). Pathological and epidemiological associations between these two diseases have been presented, but are still debated. This study aimed to investigate the association between the inflammatory burden of periodontitis and the presence and extent of coronary calcification. Secondary aims were to study other cardiovascular parameters and cardiovascular risk predictors in relation to periodontitis and dental health. Methods Healthy periodontitis or non-periodontitis patients 45-70 years of age were included in a prospective cross-sectional study. Full-mouth examinations were performed by a periodontist to determine their Periodontal Inflamed Surface Area (PISA) score and other dental parameters. To assess the cardiovascular conditions, Coronary Artery Calcium (CAC) scores, endothelial function assessments by the EndoPAT ™, and several physical and biochemical examinations were performed. Results Seventy-one patients were included. Elevated CAC scores and endothelial dysfunction were not significantly related to PISA or dental health. PISA was significantly related to the Framingham and Reynolds CVD risk predictors, but were no longer significant after correction for confounders. The same applied to the significant relations between tooth loss, dental plaque and bleeding scores and the CVD risk predictors. Conclusions Periodontitis is associated with increased CVD risk, but is not an independent risk factor. This link is still important to make to bridge the gap between dentistry and general medicine and to identify patients at risk for CVD in an earlier stage.

Elevated Coronary Artery Calcium scores are associated with tooth loss. PLoS One 2020; 15:e0243232.

Abstract
Aim This study explores the association between Coronary Artery Calcium (CAC) scores and dental pathology such as missing teeth, the (peri-apical) health status and restoration grade of the teeth, and the grade of alveolar bone loss seen on a dental panoramic radiograph (Orthopantomograph–OPG). Materials and methods In this retrospective cross-sectional study, data was collected from three hospitals spread in the Netherlands. Patients were included when a CAC score and an OPG were available, both recorded within a maximum period of 365 days from 2009–2017. The CAC score was measured on a CT scan, using the Agatston method. To assess dental pathology, the number of missing teeth, the number of dental implants, alveolar bone loss, caries, endodontic treatments, peri-apical radiolucencies, bone loss at implants, impacted teeth and dental cysts, were determined on the OPG. All observers were calibrated. The electronic health records provided information about: gender, age, smoking, Diabetes Mellitus, hypercholesterolemia, hypertension and Body Mass Index (BMI). Results 212 patients were included. We found a statistically significant association between the number of missing teeth and the CAC score. When modeling age, sex, and other well-known risk factors for cardiovascular disease, the significant correlation was no longer present after multivariate correction. Furthermore, the results showed a trend for more teeth with peri-apical lesions and a higher percentage of mean alveolar bone loss in the group with the highest CAC scores. Conclusion This study showed that being edentulous or missing teeth is correlated to higher CAC scores however failed to be an independent predictor of atherosclerotic cardiovascular diseases. The number of (missing) teeth is an easily accessible marker and could be used as a marker for atherosclerotic cardiovascular disease (ACVD) risk by almost any healthcare worker. The current study needs to be considered as an explorative pilot study and could contribute to the design of further (prospective) studies on the relationship between dental pathology and coronary artery calcification by adding clinical information and extra cardiovascular biomarkers.

Abstract
AIM To determine the scientific evidence regarding the condition of periodontal diseases (PDs) as risk factors of coronary artery diseases. MATERIALS AND METHODS A scoping review was performed through the selection of articles from online databases (Medline via PubMed, LILACS, and Cochrane CENTRAL), using a search algorithm and eligibility criteria for data extraction and data synthesis of included papers. Four hundred forty-one studies from online databases and 1364 from reference lists were initially identified, and 34 articles were selected for inclusion. Articles had to be published between 2015 and 2020 and had to associate PDs to coronary arterial diseases. All studies comprised a sample of 446443 participants. Favorable opinions totaled 70.59%, and the cross-sectional observational study design was more frequently found (32.35%). Biochemical outcomes were showed more frequently, such as inflammatory biomarkers (58.82%). Despite a large advantage for favorable opinions, a statistically significant result was not found when extracted data were combined with studies opinions. CONCLUSION The evidence was classified as level II-3, hence, still distant from the best ranks and can therefore be considered as unclear. Moreover, studies with the higher potential to generate evidence showed a high risk of bias.

Abstract
OBJECTIVE AND BACKGROUND To study the relationship between periodontitis and vascular calcification by establishing rat model of chronic periodontitis and vascular calcification. METHODS Forty male Wistar rats were divided into four groups randomly: control group, periodontitis group, vascular calcification group, and compound periodontitis and calcification group. Each group rats accepted the corresponding manages to establish the animal model. Clinical examinations and hematoxylin and eosin staining of periodontal tissue were taken to test the periodontal model; calcium assay, alkaline phosphatase activity, expression of mineral-related factors including osteopontin, alkaline phosphatase, core-binding factor-α1 and bone sialoprotein, hematoxylin and eosin staining and von Kossa staining of vascular tissue were taken to test the vascular calcification model; inflammatory factors including C-reactive protein, interleukin-1β, tumor necrosis factor-α, interleukin-6, prostaglandin E2, and serum lipid in serum were also detected at the same time. RESULTS The rat model was established. Inflammation of periodontal tissue and alveolar bone resorption in compound group and periodontitis group were more obvious than those in control group and vascular calcification group (P < .05). However, the calcium assay, alkaline phosphatase activity, and mineralized deposition in vascular calcification group and compound group were higher than those in control group and periodontitis group (P < .05), and compound group were the highest (P < .05); as for serum lipid, the level of total cholesterol and low-density lipoprotein-cholesterol in compound group and vascular calcification group were higher than that in control group and periodontitis group (P < .05), and compound group was the highest (P <.05); but the level of high-density lipoprotein cholesterol was higher in control group and periodontitis group. Inflammatory factors expression in serum were higher in compound group and periodontitis group, while mineral-related factors expression were higher in compoundgroup and vascular calcification group. CONCLUSION There are some mutual promotions between periodontitis and vascular calcification, which might be related to the increasing inflammatory factors, lipids level, and mineral-related factors.

Abstract
AIM To assess the role of periodontal disease (PD) as a predictor of coronary artery disease (CAD) and mortality in a prospective type 1 diabetes (T1D) cohort and to evaluate the role of smoking in this relationship. METHODS Data were based on 320 participants of the Pittsburgh Epidemiology of Diabetes Complications study of T1D who, during 1992-94, received a partial mouth periodontal exam, and who were followed for up to 19 years to ascertain complication incidence. PD was defined as clinical attachment loss of ≥4 mm for at least 10% of the examined sites. Predictors of all-cause mortality; Hard CAD (CAD death, myocardial infarction or revascularization), and Total CAD (Hard CAD, angina, ischemic ECG) were assessed using Cox models. RESULTS During 19 years of follow-up, 33.7% (97/288) developed CAD, 27.3% (83/304) developed Hard CAD, and 16.9% (54/320) died. Among current smokers, 46.4% (26/56) developed CAD, 42.7% (24/56) developed Hard CAD and 29.5% (18/61) died. PD was not associated with all-cause mortality, although it was a significant predictor of both CAD (HR = 1.12, CI = 1.01-1.23) and Hard CAD (HR = 1.30, CI = 1.11-1.51). As smoking modified the PD-CAD and PD-Hard CAD associations, analyses were stratified by smoking status. PD was associated with an increased risk of CAD (HR = 1.25, CI = 1.03-1.50) and Hard CAD (HR = 1.85, CI = 1.17-2.93) only among smokers. CONCLUSION PD was a significant predictor of CAD and Hard CAD among current smokers with T1D.

Abstract
Previous evidence connects periodontal disease, a modifiable condition affecting a majority of Americans, with metabolic and cardiovascular morbidity and mortality. This review focuses on the likely mediation of these associations by immune activation and their potential interactions with mental illness. Future longitudinal, and ideally interventional studies, should focus on reciprocal interactions and cascading effects, as well as points for effective preventative and therapeutic interventions across diagnostic domains to reduce morbidity, mortality and improve quality of life.

Abstract
BACKGROUND/PURPOSE Type 1 diabetes mellitus (T1DM) is a chronic autoimmune disease affecting oral health. Evidence shows possible association between T1DM and periodontal diseases (PDs). We conducted a nationwide population-based study in Taiwan, with a 14-year follow-up to investigate the risk of PDs in T1DM patients. METHODS We used data from the National Health Insurance Research Database in Taiwan. The T1DM cohort was identified with newly diagnosed T1DM from 1998 to 2011. The non-T1DM cohort was frequency matched with the T1DM cohort. Participants comprised 4248 patients in the T1DM cohort and 16992 persons in the non-T1DM cohort. RESULTS The T1DM patients showed an increased risk of PDs compared to non-T1DM individuals [adjusted hazard ratio (aHR) = 1.45]. T1DM patients who visited the emergency room more than twice per year had a higher aHR of 13.0 for developing PDs. The aHR for PDs was 13.2 in the T1DM patients who had been hospitalized more than twice per year. CONCLUSION T1DM patients are at higher risk of developing PDs than non-T1DM individuals. Our results further showed that the number of T1DM interventions; that is, annual emergency visits and hospitalizations were associated with increased the risk of developing PDs.

Abstract
Periodontal and cardiovascular disease are both major health issues. Poor oral health has long been associated with the development of systemic diseases, with the typical example being the risk of endocarditis posterior to dental procedures. Through the years, the association of periodontal disease with other non-infectious systemic diseases has been brought to attention. One of the most interesting associations is the one that exists with the development of cardiovascular disease. Many studies, including systematic reviews and meta-analyses, suggest an important association between periodontal disease and ischaemic heart disease, cerebrovascular disease, heart failure, atrial fibrillation and peripheral artery disease. Among the proposed mechanisms of this relationship, systemic inflammation appears to play a major role. Evidence suggests that periodontal inflammation triggers a systemic inflammatory state that, added to the damage mediated by antibodies that cross react between periodontal pathogens and components of the intimal wall, and the direct lesion of the intima by bacteria entering the circulation, promotes atheroma plaque development and progression. There are other studies that show a clear relationship between periodontal disease severity, elevations of inflammatory markers, and the presence of atherosclerosis. Here, we give a review of the available evidence supporting this association, and the possible mechanisms involved.

Abstract
Abstract
Periodontal disease is a chronic inflammatory disease that results from the activity of altered oral microbiome, leading to altered immune reaction, destruction of tissues supporting the teeth, and oral bone loss. This disease is particularly associated with an expressed systemic inflammation, being considered nowadays an inflammatory disorder. At the same time, inflammation has been recognized to play a major role in the development of atherosclerotic lesions. Atheromatous plaque formation is triggered by alterations in the structure of the endothelium, which lead to the expression of adhesion molecules and recruitment of immune cells such as macrophages, in the arterial wall. While the association between periodontal disease, inflammation and cardiovascular diseases has been well established, the causality relation between these three entities has not been demonstrated so far. This review presents the most common advances in understanding the complex link between periodontal disease, inflammation and atherosclerosis, as a common pathway leading to increased cardiovascular risk.

Abstract
BACKGROUND A subset of periodontal microorganisms has been associated with cardiovascular disease (CVD), which is the leading complication of type 1 diabetes (t1DM). The authors therefore evaluated the association between periodontal microorganism groups and early markers of CVD in youth with t1DM. METHODS A cross-sectional analysis was conducted among youth aged 12 to 19 years at enrollment; 105 had t1DM for ≥5 years and were seeking care at the Barbara Davis Center, University of Colorado, from 2009 to 2011, and 71 did not have diabetes. Subgingival plaque samples were assessed for counts of 41 periodontal microorganisms using DNA-DNA hybridization. Microorganisms were classified using cluster analysis into four groups named red-orange, orange-green, blue/other, and yellow/other, modified from Socransky's color scheme for periodontal microorganisms. Subsamples (54 with t1DM and 48 without diabetes) also received a periodontal examination at the University of Colorado School of Dental Medicine. RESULTS Participants were ≈15 years old on average, and 74% were white. Mean periodontal probing depth was 2 mm (SE 0.02), and 17% had bleeding on probing. In multivariable analyses, glycated hemoglobin (HbA1c) was inversely associated with the yellow/other cluster (microorganisms that are not associated with periodontal disease) among youth with t1DM. Blood pressure, triglycerides, low-density lipoprotein, high-density lipoprotein, and total cholesterol were not associated with microorganism clusters in this group. HbA1c was not associated with periodontal microorganism clusters among youth without diabetes. CONCLUSION Among youth with t1DM who had good oral health, periodontal microorganisms were not associated with CVD risk factors.
