Use of floss/interdental brushes is associated with lower risk for new cardiovascular events among patients with coronary heart disease

Cardiovascular Health Behavior Prediction Model in Patients With Type 2 Diabetes

BACKGROUND

To prevent cardiovascular disease in adults with type 2 diabetes, it is necessary to identify the factors that affect cardiovascular health behavior.

OBJECTIVE

The aim of this study was to verify the causal relationship between illness perception and diabetes knowledge as cognitive representations, depression as emotional representations, self-efficacy as cognitive coping, and oral health and cardiovascular health behaviors as behavioral coping strategies. A hypothetical model was established based on a literature review and the self-regulation model.

METHODS

In this study, a cross-sectional survey design was used, and the participants were adults 30 years or older who had been given a diagnosis of type 2 diabetes for more than 6 months and were recruited from South Korea. Data from 272 participants were collected through face-to-face interviews or Google surveys in 2021, and analyzed using SPSS 25.0 and AMOS 22.0.

RESULTS

Oral health behavior (β = 0.26, P < .001) and self-efficacy (β = 0.16, P = .048) had a direct effect on cardiovascular health behavior, and illness perception (β = 0.24, P = .018) and depression (β = -0.25, P < .001) had an indirect effect through self-efficacy (β = 0.24, P = .016), with a total explanatory power of 19.1%. Oral health behavior was directly affected by illness perception and self-efficacy, and self-efficacy was directly affected by illness perception, diabetes knowledge, and depression ( P < .05).

CONCLUSION

To practice cardiovascular health behaviors in adults with diabetes, self-efficacy for diabetes management should be enhanced. To this end, it is necessary to increase illness perception and knowledge, and reduce depression through cardiovascular disease prevention education for them, and the importance of oral health behaviors should also be emphasized.

Edentulism or Poor Oral Hygiene: Which Is the Stronger Predictor for All-Cause Mortality?

Background: All-cause mortality consisting of several heterogeneous subgroups does not have a well-defined set of risk factors. Despite the well-described role of oral hygiene on mortality, the association between the condition of the existing dentition and mortality remains unclear. Therefore, we embarked on the current study to assess the association of oral hygiene self-care (OHS) with all-cause mortality. Methods: We assessed whether edentulism and the levels of OHS are associated with all-cause mortality in 476 subjects without missing values participating in the KOHH study using proportional hazard models. We designated the edentulous group as OHS0, and poor, fair, and good OHS groups as OHS1, OHS2, and OHS3, respectively. The self-reported OHS was validated against clinical measures of oral inflammation and dental cleanliness, i.e., gingival bleeding and plaque indices. We, then, compared all-cause mortality at three levels of OHS (poor, fair, good) to that of the edentulous group. To test whether the association of OHS to all-cause mortality was mediated by inflammation, we adjusted for CRP. Results: The validity of self-reported OHS was good demonstrating an inverse association with gingival inflammation and plaque index in a dose-response manner. The group with good OHS lived significantly longer, with a 50% lower risk of all-cause mortality. The Hazard ratio (HR) = 0.50 (95% confidence limit: 0.25-0.99), p = 0.045, in a model adjusted for age, smoking, body mass index, and education. Adjusting for CRP attenuated the association of OHS to all-cause mortality slightly, suggesting that this association was mediated, at least in part, by inflammation. In the final model, the poor OHS group exhibited HR = 0.98 (0.51-1.89), p = 0.95. The HR and p-value so close to 1 suggested poor OHS has a similar risk to edentulism. Conclusions: OHS was associated with reduced risk for all-cause mortality: the better OHS, the lower the risk for all-cause mortality. Poor oral hygiene showed a similar risk for all-cause mortality to edentulism.

The effect of self-reported flossing behavior on cardiovascular disease events and mortality: Findings from the 2009-2016 National Health and Nutrition Examination Surveys

BACKGROUND

There is increasing evidence suggesting that daily oral hygiene self-care measures may alleviate cardiovascular disease (CVD) risk. The authors aimed to determine the influence of self-reported dental flossing behavior on the prevalence of CVD events, CVD-linked mortality, and a CVD risk marker of inflammation (ie, C-reactive protein [CRP]).

METHODS

Data from 18,801 adult participants of the 2009-2016 National Health and Nutrition Examination Surveys were analyzed with regard to flossing behavior, prevalence of CVD events, mortality cause data, and CRP levels. Information on mortality was obtained from the US mortality registry, updated to 2019. Participants who answered the flossing question were divided into 4 groups according to their frequency of flossing: not flossing (0 d/wk); occasional flossing (1-3 d/wk); frequent flossing (4-6 d/wk); and daily flossing (7 d/wk). Multiple logistic regression and Cox proportional hazard regression were used for analysis.

RESULTS

Daily flossing was associated with lower prevalence of CVD events after adjusting for age, sex, sociodemographic factors, and lifestyle habits (model 2); the odds ratio was 0.71 (95% CI, 0.59 to 0.85) for CVD prevalence in the daily flossing group compared with the not flossing group. The odds ratio for CVD prevalence for each additional day of flossing was 0.95 (95% CI, 0.93 to 0.98; P for linear trend < .001) in model 2, and remained statistically significant after model 2 was further adjusted for metabolic syndrome. Daily flossing compared with not flossing was associated with lower risk of experiencing CVD mortality (hazard ratio, 0.64; 95% CI, 0.49 to 0.84) in model 2. The hazard ratio of CVD mortality for each additional day of flossing was 0.94 (95% CI, 0.90 to 0.98; P for linear trend = .002) in model 2. Participants in the not flossing group had significantly elevated CRP levels, even after multivariable adjustments.

CONCLUSIONS

Poor flossing behavior is associated with higher prevalence of cardiovascular events, increased risk of experiencing CVD mortality, and elevated CRP levels.

PRACTICAL IMPLICATIONS

Improvement in flossing behavior can have an additional benefit in the prevention of CVD events. Cardiologists need to advise patients to improve their personal oral hygiene practices, in addition to the standard diet and exercise advice.

Impact of Oral Hygiene Practices in Reducing Cardiometabolic Risk, Incidence, and Mortality: A Systematic Review

Cardiometabolic diseases share many modifiable risk factors. However, periodontitis, a chronic inflammatory condition of the gums, is a risk factor that is rarely publicized. This systematic review aims to evaluate the impact of oral hygiene practices on the risk, incidence, and/or mortality rate of cardiovascular disease (CVD), type 2 diabetes mellitus (T2DM), and chronic kidney disease (CKD). Searches were conducted using MEDLINE, Embase, Scopus, and CINHAL. Randomized controlled trials (RCTs), quasi-RCTs, and observational studies were included. Eligible studies reported on associations of toothbrushing, interdental cleaning, mouthwash, or toothpaste use, either alone or in combination with CVD, CKD, and/or T2DM outcomes in adults ≥ 18 years. Fifty-five studies were included. Cochrane's risk of bias tool and the Newcastle-Ottawa Scale were used for quality assessment. Data synthesis is narratively presented. Toothbrushing and interdental cleaning were associated with lower risk of developing T2DM or hypertension HR 0.54 [p < 0.001] and a lower mortality risk in those with CVD HR = 0.25 [p = 0.03]. Mouthwash use reportedly increased the risk of developing hypertension and diabetes by 85% and 55%, respectively. This review highlights how simple oral hygiene practices can reduce cardiometabolic risk. Non-dental clinicians could integrate the findings into chronic disease health promotion.

Major Adverse Cardiovascular Events: The Importance of Serum Levels and Haplotypes of the Anti-Inflammatory Cytokine Interleukin 10

BACKGROUND

Cardiovascular diseases (CVDs) represent major medical and socio-economic challenges worldwide. There is substantial evidence that CVD is closely linked to inflammatory changes triggered by a complex cytokine network. In this context, interleukin 10 (IL-10) plays an important role as a pleiotropic cytokine with an anti-inflammatory capacity. In this study (a substudy of ClinTrials.gov, identifier: NCT01045070), the prognostic relevance of IL-10 levels and IL-10 haplotypes (rs1800896/rs1800871/rs1800872) was assessed regarding adverse cardiovascular outcomes (combined endpoint: myocardial infarction, stroke/transient ischemic attack, cardiac death and death according to stroke) within a 10-year follow-up.

PATIENTS AND METHODS

At baseline, 1002 in-patients with CVD were enrolled. Serum levels of IL-10 were evaluated utilizing flow cytometry (BD™ Cytometric Bead Array). Haplotype analyses were carried out by polymerase chain reactions with sequence-specific primers (PCR-SSP).

RESULTS

In a survival analysis, IL-10 haplotypes were not proven to be cardiovascular prognostic factors in a 10-year follow-up (Breslow test: p = 0.423). However, a higher IL-10 level was associated with adverse cardiovascular outcomes (Breslow test: p = 0.047). A survival analysis considering adjusted hazard ratios (HRs) could not confirm this correlation (Cox regression: adjusted HR = 1.26, p = 0.168).

CONCLUSION

In the present study, an elevated IL-10 level but not IL-10 haplotypes was linked to adverse cardiovascular outcomes (10-year follow-up) in a cohort of CVD patients.

Dental caries prevalence in relation to the cardiovascular diseases: cross-sectional findings from the Iranian kurdish population

OBJECTIVE

Oral and dental health (ODH) is a significant public health concern globally, affecting billions of people. This cross-sectional study aimed to examine the prevalence of dental caries using the DMFT index and investigate its relationship with cardiovascular diseases in the Iranian Kurdish population.

METHODS

A total of 3,996 individuals aged 35-70 years were included from the Dehgolan prospective cohort study (DehPCS). Clinical examinations were performed to assess decayed (DT), missing (MT) and filled (FT) teeth (DMFT index). Data on demographics, socioeconomic status, medical history, oral hygiene practices were also collected. Cardiovascular disease (CVD) history was self-reported via questionnaires assessing heart disease, heart attack and stroke. Logistic regression was used to assess associations between oral health indicators and self-reported CVD, adjusting for potential confounders.

RESULTS

The mean DMFT score was 18.18 ± 19, indicating a high oral disease burden. Specifically, 60.04% had DT, 37.82% had more than 16 MT, and 38.83% had FT. Only 13.21% reported flossing regularly and 43.17% brushed less than daily, showing suboptimal oral hygiene. The overall CVD prevalence was 9.21%. Individuals with high DMFT (≥ 14) scores had approximately two times higher CVD prevalence than those with low DMFT. DMFT decreased by 10.23% with increase in education level, and by 5.87% as economic status increased In adjusted analyses, high DMFT scores (OR = 1.5, 95%CI: 1.2-1.9) and MT (OR = 1.5, 95%CI: 1.1-2.1) were associated with 50-150% increased odds of CVD, though associations weakened after adjusting for age. Among men, DMFT remained a significant predictor for CVD after age adjustment, with an odds ratio of 2.37 (95% CI: 1.22-4.60).

CONCLUSION

This population had substantial oral disease and poor oral hygiene. Higher DMFT scores and MT positively correlated with increased CVD prevalence. Promoting preventive oral care and health education could help reduce dental issues and potentially lower CVD risk. Further research is needed to clarify biological mechanisms linking oral and systemic health.

Biofilm volume and acidification within initial biofilms formed in situ on buccally and palatally exposed bracket material

PURPOSE

Acidification by bacterial biofilms at the bracket/tooth interface is one of the most common problems in fixed orthodontic treatments, which can lead to white spot lesions (WSL) and caries. As lingual brackets were shown to exhibit reduced WSL formation clinically, the aim of this in situ study was to compare initial intraoral biofilm formation and acidification on bracket-like specimens placed buccally and palatally in the upper jaw as a possible cause for this observation.

METHODS

Intraoral biofilm was collected from splints equipped with buccally and palatally exposed test specimens, which were worn by 12 volunteers for a total of 48 h. The test specimens consisted of standard bracket material cylinders on top of a hydroxyapatite disc to represent the bracket/tooth interface. They were analyzed for three-dimensional biofilm volume and live/dead distribution by fluorescence staining and confocal laser scanning microscopy as well as for acidification by fluorescence-based pH ratiometry.

RESULTS

Similar general biofilm morphology with regard to volume and viability could be detected for buccally and palatally exposed specimens. For pH values, biofilms from both positions showed increased acidification at the bottom layer. Interestingly, the pH value at the top layers of the biofilms was slightly lower on palatally than on buccally exposed specimens, which may likely be due to anatomic conditions.

CONCLUSION

Based on the results of this study, initial intraoral biofilm formation and acidification is almost similar on the bracket material/biomimetic tooth interface when placed buccally or palatally in the upper jaw. As lingual brackets were shown to exhibit reduced WSL formation clinically, future studies should investigate further factors like bracket geometry.

The Interleukin 6 Protein Level as well as a Genetic Variants, (rs1800795, rs1800797) Are Associated with Adverse Cardiovascular Outcomes within 10-Years Follow-Up

BACKGROUND

Worldwide, cardiovascular disease (CVD) is the leading cause of premature death. The proinflammatory cytokine interleukin 6 (IL-6) is a essential marker of innate immunity that is considered to play an important proatherogenic role for cardiovascular disease. The aim of this study (substudy of ClinTrials.gov identifier: NCT01045070) was to evaluate IL-6 protein level and genetic variants (rs1800795, rs1800797) with respect to CV outcome (combined endpoint: myocardial infarction, stroke/transient ischemic attack, cardiac death, death according to stroke) among patients CVD within 10-years follow-up.

MATERIAL AND METHODS

Overall 1002 in-patients with CVD were included. IL-6 protein level was determined by electrochemiluminescence immunoassay (fasting, between 7 and 8 a.m.). Genetic analyses were carried out by single specific primer-polymerase chain reaction.

RESULTS

In survival analyses, IL-6 protein levels of ≥6.4 pg/mL (log-rank test: p = 0.034; cox regression: p = 0.032, hazard ratio = 1.29) and CC genotype of rs1800795 (log-rank test: p < 0.001, cox regression: p < 0.001, hazard ratio = 1.72) and AA genotype of rs180797 (log-rank test: p = 0.002, cox regression: p < 0.001, hazard ratio = 1.62) were associated with a poorer CV prognosis considering combined CV endpoint.

CONCLUSION

This study was the first to investigate both elevated IL-6 levels and genetic variants for their prognostic value for adverse CV outcomes in CVD patients within the 10-year follow-up period.

C-Reactive Protein Level and the Genetic Variant rs1130864 in the CRP Gene as Prognostic Factors for 10-Year Cardiovascular Outcome

BACKGROUND

Cardiovascular disease (CVD) is the primary cause of premature death and disability worldwide. There is extensive evidence that inflammation represents an important pathogenetic mechanism in the development and prognosis of CVD. C-reactive protein (CRP) is a potential marker of vascular inflammation and plays a direct role in CVD by promoting vascular inflammation. The objective of this study (ClinTrials.gov identifier: NCT01045070) was to assess the prognostic impact of CRP protein levels and genetic variants of CRP gene events on cardiovascular (CV) outcome (10-year follow-up) in patients suffering from CVD.

METHODS

CVD patients were prospectively included in this study (n = 1002) and followed up (10 years) regarding combined CV endpoint (CV death, death from stroke, myocardial infarction (MI), and stroke/transient ischemic attack (TIA)). CRP protein level (particle-enhanced immunological turbidity test) and genetic variants (rs1130864, rs1417938, rs1800947, rs3093077; polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) after DNA extraction from EDTA-blood) were evaluated.

RESULTS

In survival analyses, increased CRP protein levels of ≥5 mg/L (log-rank test: p < 0.001, Cox regression: p = 0.002, hazard ratio = 1.49) and CT + TT genotype of rs1130864 (log-rank test: p = 0.041; Cox regression: p = 0.103, hazard ratio = 1.21) were associated with a weaker CV prognosis considering combined CV endpoint.

CONCLUSIONS

Elevated CRP level and genetic variant (rs1130864) were proven to provide prognostic value for adverse outcome in CVD patients within the 10-year follow-up period.

Oral hygiene, mouthwash usage and cardiovascular mortality during 18.8 years of follow-up

Aim(s) We tested the following hypotheses: would better oral hygiene self-care (OHS) influence cardiovascular (CVD) mortality? Will using mouthwash in addition to OHS affect CVD mortality? How does mouthwash usage impact the oral microbes?Design and methods Among 354 dentate subjects from the Kuopio Oral Health and Heart study, the association of OHS with CVD mortality was assessed using Cox regression analyses, adjusting for age, sex, smoking, dyslipidemia, diabetes, hypertension and education. Additionally, whether using mouthwash would affect this relationship was evaluated.Results In the multivariable-adjusted models, OHS was associated with a 51% reduction in the risk of CVD mortality (hazard ratio [HR] 0.49 [0.28-0.85]; p = 0.01). Even those who had coronary artery disease at baseline showed a marginally significant benefit (0.50 [0.24-1.06]; p = 0.07). However, mouthwash usage did not change OHS effects (HR = 0.49 [0.27-0.87]; p = 0.01), indicating no additional benefits nor detriments. All tested microbes trended to decrease with mouthwash usage in the short term, but none were statistically significant.Conclusion Good OHS significantly lowered the risk of CVD mortality relative to poor OHS. Mouthwash usage did not show any long-term harm or benefit on CVD mortality beyond the benefits rendered by brushing and flossing.

Periodontitis and Number of Teeth in the Risk of Coronary Heart Disease: An Updated Meta-Analysis

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.

Lower Number of Teeth Is Related to Higher Risks for ACVD and Death-Systematic Review and Meta-Analyses of Survival Data

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.

Oral health in adults with coronary artery disease and its risk factors: a comparative study using the Korea National Health and Nutrition Examination Survey data

Background

This study aimed to examine the relationship between oral health status and hygiene behavior among adults and elderly with preceding chronic disease or coronary artery disease history.

Methods

Data were obtained from the Korea National Health and Nutrition Examination survey conducted from 2016 to 2017. Cardiovascular risk group was defined as adults over the age of 30 with hypertension, diabetes, dyslipidemia, previous myocardial infarction, or angina. Adult and elderly groups were separated and analyzed by 1:1 propensity score matching (PSM), and complex sample logistic regression analysis was performed using SPSS and R programs.

Results

In adults, 25.1% of healthy group and 41.9% of the risk group were diagnosed with periodontal disease by dentist. In the elderly, 40.0% of the risk group had chewing problems and 17.5% had speaking problems. After PSM, in adults (n = 1661 each), both univariate and multiple logistic regression analyzes showed that the prevalence of periodontal disease was significantly higher in the risk group than in the healthy group (Odds Ratio = 1.21, p = .028). In the elderly (n = 715 each), univariate analysis showed that the risk group had more chewing and speaking problems than the healthy group, but there was no difference in multivariate analysis.

Conclusions

Adults under the age of 65 years with cardiovascular risk require periodic evaluation and education on the importance of maintaining oral health for primary or secondary prevention. Healthcare professionals should provide patient education to help them maintain adequate oral health and oral hygiene.

Hypertension and Its Associations with Dental Status: Data from the Dental, Oral, Medical Epidemiological (DOME) Nationwide Records-Based Study

Conflicting results have been published regarding the associations between dental status and hypertension. This study aims to explore whether or not hypertension is associated with dental status among young to middle-aged adults. To that end, data from the Dental, Oral, Medical Epidemiological (DOME) study were analyzed. The DOME is a cross-sectional records-based study that combines comprehensive socio-demographic, medical, and dental databases of a nationally representative sample of military personnel. Included were 132,529 subjects aged 18–50 years who attended the military dental clinics for one year. The prevalence of hypertension in the study population was 2.5% (3363/132,529). Following multivariate analysis, the associations between hypertension and dental parameters were lost and hypertension retained a positive association with obesity (Odds ratio (OR) = 4.2 (3.7–4.9)), diabetes mellitus (OR = 4.0 (2.9–5.7)), birth country of Western Europe vs. Israeli birth country (OR = 1.9 (1.6–2.2)), male sex (OR = 1.9 (1.6–2.2)), cardiovascular disease (OR = 1.9 (1.6–2.3)), presence of fatty liver (OR = 1.8 (1.5–2.3)), the birth country Asia vs. Israeli birth country (OR = 1.6 (1.1–2.3)), smoking (OR = 1.2 (1.05–1.4)), and older age (OR = 1.05 (1.04–1.06)). Further analysis among an age-, smoking- and sex matched sub-population (N = 13,452) also revealed that the dental parameters lost their statistically significant association with hypertension following multivariate analysis, and hypertension retained a positive association with diabetes (OR = 4.08 (2.6–6.1)), obesity (OR = 2.7 (2.4–3.2)), birth country of Western Europe vs. Israel (OR = 1.9 (1.6–2.3)), cardiovascular disease (OR = 1.8 (1.5–2.2)), fatty liver (OR = 1.7 (1.3–2.3)), high school education vs. academic (OR = 1.5 (1.3–1.8)), and low socio-economic status (SES) vs. high (OR = 1.4 (1.03–1.8)). We analyzed the associations between C-reactive protein (CRP) and dental parameters and combined the statistically significant variables to create a dental inflammation score (DIS). This crated a final model with the appropriate weights written as follows: DIS = (periodontal disease × 14) + (the number of teeth that required crowns × 11) + (missing teeth × 75). The mean DIS was 10.106 ± 25.184, and it exhibited a weak positive association with hypertension in the univariate analysis (OR = 1.011 (1.010–1.012)). Receiver operating characteristic (ROC) analysis of the DIS against hypertension produced a failed area under the curve (AUC) result (0.57 (0.56–0.58)). Moreover, the DIS also lost its statistical significance association with hypertension following multivariate analysis. We conclude that hypertension had no statistically significant nor clinically significant association with dental status. The study established a profile of the “patient vulnerable to hypertension”, which retained well-known risk factors for hypertension such as older age, male sex, smoking, diabetes, obesity, and fatty liver but not dental parameters.

Exploring the periodontal disease-ischemic stroke link

Multiple risk factors are associated with ischemic stroke. Here, we highlight studies indicating that periodontal disease significantly increases the risk of both primary ischemic stroke and subsequent cardiovascular events. Additionally, studies have shown an association between periodontal disease and multiple causes of ischemic stroke. Finally, we describe an ongoing clinical trial testing the benefit of periodontal disease treatment as a strategy to reduce risk for recurrent cardiovascular events in patients who have had recent ischemic stroke or transient ischemic attack. This article is mostly based on a presentation given in honor of Steven Offenbacher (1950 to 2018).

Oral Health Knowledge Level of Nursing Staff Working in Semi-Intensive Heart Failure Units

PURPOSE

Critical care units, such as heart failure units, house inpatients with a compromised general health status that requires rigorous prevention of further complications. Oral health infections that gain access through the bloodstream or airway might represent such potential complications (eg, endocarditis pneumonia). Avoiding these critical occurrences requires that adequate oral health care be provided by nursing personnel. Here we assessed the knowledge of oral health care practices by nurses working in three Italian heart failure units in Umbria, Italy.

DESIGN

This was a cross-sectional study.

METHODS

Forty-four nurses were interviewed using a six-item modified Adams' questionnaire on the topic of oral health care. A multidisciplinary panel of experts established the criteria for answer correctness based on the most relevant dentistry literature evidence and judged each reply. The expected percentage of correctly replying nurses was 75%, and significant differences from this expected probability were calculated with one-sided binomial probability tests. Cronbach's α method was used to establish the questionnaire's internal consistency (reliability).

RESULTS

For five out of six questionnaire items, the percentage of nurses who correctly answered was significantly lower than the expected value of probability. Lack of knowledge was found for usefulness of checking the patients' mouths (p=0.003), the most relevant lesions affecting the mouth (p=0.0001), the tools/solutions for cleaning the mouth and dentures (p= 0.0416), and drugs that affect the mouth and their side effects (p<0.0001).

CONCLUSION

In this study, few nurses working in heart failure units showed both an adequate willingness to check inpatients and a good knowledge of oral health care (significantly lower than the expected 75%). Further studies that use validated questionnaires and include more participants should be conducted to confirm and elaborate on our preliminary data.

Poor Oral Health Predicts Higher 10-Year Cardiovascular Risk: A Propensity Score Matching Analysis

BACKGROUND

Although the association between periodontitis and cardiovascular disease (CVD) has been reported, whether periodontitis and poor oral health behavior influence CVD risk remains unclear.

OBJECTIVE

The aim of this study was to examine whether periodontal disease and poor oral health behavior predict 10-year general CVD risk using the Framingham Risk Score.

METHODS

Patients older than 30 years with no CVD history (n = 8370) were selected using cross-sectional study data from the Korean National Health and Nutrition Examination Survey in 2013 and 2014. To reduce selection bias in this population-based study, propensity score matching analysis was used with SPSS and R programs to compare CVD risk.

RESULTS

Overall, 39.2% of the study population (n = 3277) had a global CVD risk of  10% or greater. In the low- and at-risk groups, 20.7% and 45.3% of patients, respectively, were diagnosed with periodontal disease by a dentist. Moreover, 43.2% and 62.8% of the low- and at-risk group patients, respectively, brushed teeth less than 3 times a day. After 1:1 propensity score matching of the low-risk (n = 1135) and at-risk (n = 1135) groups, bivariate analyses showed that a diagnosis of periodontal disease and less frequent toothbrushing were associated with a higher CVD risk (P < .001). Logistic regression analysis also showed that patients having periodontal disease and who brushed teeth less frequently were 1.38 and 1.33 times, respectively, more likely to be at risk of CVD (P < .001).

CONCLUSION

Education on periodontitis management and oral hygiene behavior should be included, when strategies for public risk reduction of CVD are developed.

Oral health of high-cost patients and evaluation of oral health measures as predictors for high-cost patients in South Korea: a population-based cohort study

OBJECTIVE

To examine the oral health conditions and oral health behaviour of high-cost patients and evaluate oral health measures as predictors of future high-cost patients.

DESIGN

A retrospective, population-based cohort study using administrative healthcare records.

SETTING

The National Health Insurance Service (NHIS) medical check-up database (a.k.a. NHIS-national health screening cohort database) in South Korea.

PARTICIPANTS

131 549 individuals who received biennial health check-ups including dental check-ups in 2011 or 2012, aged 49-88.

PRIMARY OUTCOME MEASURES

Current and subsequent year high-cost patient status.

RESULTS

High-cost patients, on average, incur higher dental costs, suffer more from periodontal disease, brush their teeth less and use secondary oral hygiene products less. Some of the self-reported oral health behaviours and oral symptom variables show statistically significant associations with subsequent year high-cost patient indicators, even after adjusting for demographic, socioeconomic, medical conditions, and prior healthcare cost and utilisation.

CONCLUSIONS

We demonstrate that oral health measures are associated with an increased risk of becoming a high-cost patient.

The oral health status, behaviours and knowledge of patients with cardiovascular disease in Sydney Australia: a cross-sectional survey

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.

Comparison of intraoral biofilm reduction on silver-coated and silver ion-implanted stainless steel bracket material : Biofilm reduction on silver ion-implanted bracket material

PURPOSE

The objective of this in situ study was to quantify the intraoral biofilm reduction on bracket material as a result of different surface modifications using silver ions. In addition to galvanic silver coating and physical vapor deposition (PVD), the plasma immersion ion implantation and deposition (PIIID) procedure was investigated for the first time within an orthodontic application.

MATERIALS AND METHODS

An occlusal splint equipped with differently silver-modified test specimens based on stainless steel bracket material was prepared for a total of 12 periodontally healthy patients and was worn in the mouth for 48 h. The initially formed biofilm was fluorescently stained and a quantitative comparative analysis of biofilm volume, biofilm surface coverage and live/dead distribution of bacteria was performed by confocal laser scanning microscopy (CLSM).

RESULTS

Compared to untreated stainless steel bracket material, the antibacterial effect of the PIIID silver-modified surface was just as significant with regard to reducing the biofilm volume and the surface coverage as the galvanically applied silver layer and the PVD silver coating. Regarding the live/dead distribution, however, the PIIID modification was the only surface that showed a significant increase in the proportion of dead cells compared to untreated bracket material and the galvanic coating.

CONCLUSIONS

Orthodontic stainless steel with a silver-modified surface by PIIID procedure showed an effective reduction in the intraoral biofilm formation compared to untreated bracket material, in a similar manner to PVD and galvanic silver coatings applied to the surface. Additionally, the PIIID silver-modified surface has an increased bactericidal effect.

How Intraday Index Changes Influence Periodontal Assessment: A Preliminary Study

It is reputed that periodontal indices remain unchanged over a 24-hour period, with great clinical significance. This preliminary study analyzes daily index changes. In 56 selected patients, full-mouth plaque score (FMPS), full-mouth bleeding score (FMBS), periodontal screening and recording (PSR) indices, and periodontal risk assessment (PRA) were recorded at baseline and three times per day (check-I: 08.30, check-II: 11.30, and check-III: 14.30), after appropriate cause-related therapy. Correlation between variables was statistically analyzed by Stata. All periodontal indices improved at the examination phase. Statistical differences were detected for FMPS comparing all thrice daily checks. Statistical differences were detected for FMBS and PRA comparing check-III with check-I and check-II. PSR showed no significant changes. The worst baseline indices produced the widest daily fluctuation at the examination phase. Significant variation of indices is directly related to clinical severity of periodontal conditions at baseline. Patients affected by severe periodontal disease may show significantly greater index changes. As indices are routinely recorded only once per day, the index daily variation has clinical significance. This greatly affects therapeutic strategy as correct periodontal assessment requires multiple evaluations at standardized times, particularly when baseline conditions are severe.

Influence of a triclosan toothpaste on periodontopathic bacteria and periodontitis progression in cardiovascular patients: a randomized controlled trial

BACKGROUND AND OBJECTIVE

Triclosan/copolymer toothpaste is effective in controlling plaque and gingivitis and in slowing the progression of periodontitis. This study describes its influence on microbiological and clinical outcomes, over a 5-year period, in patients with established cardiovascular disease (CVD).

MATERIAL AND METHODS

Four-hundred and thirty-eight patients were recruited from the Cardiovascular Unit at The Prince Charles Hospital, Brisbane, Australia, and randomized to triclosan or placebo groups. Six sites per tooth were examined annually for probing pocket depth and loss of attachment. These outcomes were analysed, using generalized linear modelling, in 381 patients who had measurements from consecutive examinations. Concurrent load of the periodontal pathogens Aggregatibacter actinomycetemcomitans, Fusobacterium nucleatum, Tannerella forsythia and Porphyromonas gingivalis was determined, using quantitative real-time PCR, in 437 patients with baseline plaque samples. Group comparisons were expressed as geometric means. The chi-square test was used to test for differences between the two groups of patients with regard to the proportion of patients with different numbers of bacterial species.

RESULTS

There was no difference in general health or periodontal status between the groups at baseline. There was a significant reduction in the number of interproximal sites showing loss of attachment between examinations, by 21% on average (p < 0.01), in the triclosan group compared with the placebo group. The prevalence of patients with F. nucleatum and A. actinomycetemcomitans was high and remained relatively constant throughout the 5 years of the study. In contrast, the prevalence of T. forsythia and P. gingivalis showed more variability; however, there was no significant difference between the groups, at any time point, in the prevalence of any organism. A significant difference in the geometric means for P. gingivalis (p = 0.01) was seen at years 1 and 4, and for F. nucleatum (p = 0.01) and in the total bacterial load (p = 0.03) at year 2; however, these differences were not statistically significant following a Bonferroni correction for multiple comparisons. There was no difference between the groups in the geometric means for each organism at year 5.

CONCLUSION

Within the limitations of the study, these data suggest that the use of triclosan/copolymer toothpaste significantly slowed the progression of periodontitis in patients with CVD but that it had little influence on key subgingival periodontopathic bacteria in these patients over the 5 years of the study.

Polymicrobial Biofilm Studies: From Basic Science to Biofilm Control

Microbes rarely exist as single species planktonic forms as they have been commonly studied in the laboratory. Instead, the vast majority exists as part of complex polymicrobial biofilm communities attached to host and environmental surfaces. The oral cavity represents one of the most diverse and well-studied polymicrobial consortia. Despite a burgeoning field of mechanistic biofilm research within the past decades, our understanding of interactions that occur between microbial members within oral biofilms is still limited. Thus, the primary objective of this review is to focus on polymicrobial biofilm formation, microbial interactions and signaling events that mediate oral biofilm development, consequences of oral hygiene on both local and systemic disease, and potential therapeutic strategies to limit oral dysbiosis.

Prevention of cardiovascular disease in rheumatoid arthritis

The increased risk of cardiovascular disease (CVD) in rheumatoid arthritis (RA) has been recognized for many years. However, although the characteristics of CVD and its burden resemble those in diabetes, the focus on cardiovascular (CV) prevention in RA has lagged behind, both in the clinical and research settings. Similar to diabetes, the clinical picture of CVD in RA may be atypical, even asymptomatic. Therefore, a proactive screening for subclinical CVD in RA is warranted. Because of the lack of clinical trials, the ideal CVD prevention (CVP) in RA has not yet been defined. In this article, we focus on challenges and controversies in the CVP in RA (such as thresholds for statin therapy), and propose recommendations based on the current evidence. Due to the significant contribution of non-traditional, RA-related CV risk factors, the CV risk calculators developed for the general population underestimate the true risk in RA. Thus, there is an enormous need to develop adequate CV risk stratification tools and to identify the optimal CVP strategies in RA. While awaiting results from randomized controlled trials in RA, clinicians are largely dependent on the use of common sense, and extrapolation of data from studies on other patient populations. The CVP in RA should be based on an individualized evaluation of a broad spectrum of risk factors, and include: 1) reduction of inflammation, preferably with drugs decreasing CV risk, 2) management of factors associated with increased CV risk (e.g., smoking, hypertension, hyperglycemia, dyslipidemia, kidney disease, depression, periodontitis, hypothyroidism, vitamin D deficiency and sleep apnea), and promotion of healthy life style (smoking cessation, healthy diet, adjusted physical activity, stress management, weight control), 3) aspirin and influenza and pneumococcus vaccines according to current guidelines, and 4) limiting use of drugs that increase CV risk. Rheumatologists should take responsibility for the education of health care providers and RA patients regarding CVP in RA. It is immensely important to incorporate CV outcomes in testing of anti-rheumatic drugs.

Lifestyle and dental attendance as predictors of oral health-related quality of life

OBJECTIVES

To evaluate the impact of health-related behaviors and dental attendance on oral health-related quality of life (OHRQoL).

METHODS

One hundred and ninety-two individuals presenting for dental treatment were included in a cross-sectional survey using a self-administered questionnaire that assessed demographics, smoking and alcohol consumption, physical activity habits, dental attendance, and dental pain utilizing a numeric rating scale (NRS). Results of the Oral Health Impact Profile (OHIP)-14 questionnaire were considered as the dependent variable. A conceptual hierarchical data analysis model from distal to proximal determinants of the median OHIP-14 total score was adopted.

RESULTS

Analysis of the OHIP-14 domains and total score revealed several significant protector characteristics: younger age, academic education, no alcohol consumption, regular physical activity, fewer smoking pack years, routine dental attendance, and lower NRS scores. Routine dental attendance was related to lower NRS scores (P < 0.001) which in turn were associated with lower OHIP-14 scores (P = 0.018). Better health-related behaviors (P = 0.039) and routine dental attendance (P = 0.029) also correlated directly with lower OHIP-14 scores.

CONCLUSIONS

Better health-related behaviors and routine dental attendance have a protective effect on OHRQoL. Clinicians should assess these behaviors during routine diagnostic workups. Global health authorities need to integrate oral and general health care and improve both OHrQoL and HrQoL.
