Association of Chronic Periodontitis With Left Ventricular Mass and Central Blood Pressure in Treated Patients With Essential Hypertension

BACKGROUND The aim of the study was to answer the question whether chronic periodontitis (CP) in patients with essential hypertension is associated with increased aortic stiffness and increased central blood pressure (CBP), which may in turn increase left ventricular mass (LVM) in those patients. CP influences LVM in hypertensive and renal patients as well as in healthy subjects; however, mechanisms involved are not clear. METHODS Fifty patients (23 men and 27 women, 51.4 +/- 5.2 years, body mass index (BMI) 29.5 +/- 4.4 kg/m(2)) with severe CP-Community Periodontal Index of Treatment Needs (CPITN) score 3-4, and 49 patients (20 men and 29 women, 49.3 +/- 5.5 years, BMI 29.9 +/- 4.8 kg/m(2)) with no or moderate CP (CPITN 0-2) were included. In all patients LVM, pulse wave velocity (PWV), and CBP were measured, and LVM index (LVMI) calculated. RESULTS Patients with a CPITN of 3-4 had higher LVM (257.3 +/- 67.9 vs. 220.3 +/- 66.4 g, P < 0.01), LVMI (105.8 +/- 23.6 vs. 92.6 +/- 24.8 g/m(2), P < 0.01) and higher central systolic (124 +/- 17 vs. 116 +/- 15 mm Hg, P < 0.05) and pulse pressure (45 +/- 11 vs. 38.7 +/- 9.8 mm Hg, P < 0.05) as compared with patients with a CPITN of 0-2. In the univariate analysis, for the total group a positive association was observed between CPITN values and LVM, LVMI, age, aortic systolic, and pulse pressure, but not with systemic blood pressure. Linear regression analysis showed an association of borderline significance (P = 0.06) between LVMI and the CPITN value. In other model, a significant positive relationship between CBP and CPITN was observed. CONCLUSIONS More severe forms of periodontitis are associated with increased CBP and LVM in patients with primary hypertension.

The Association Between Dental Status and Systemic Lipid Profile and Inflammatory Mediators in Patients After Myocardial Infarction

BACKGROUND Many epidemiological studies have proven that local infection may influence the levels of systemic lipid profile and inflammatory mediators. OBJECTIVES The aim of this research was to evaluate the association between the state of the oral cavity, lipids and inflammatory mediator concentrations in Poles after acute myocardial infarction (MI). MATERIAL AND METHODS A total of 134 subjects with a mean age of 54.3 years (± 8.1) were included in the study. Sociodemographic and cardiologic variables were gathered. Subsequently, serum samples were collected for estimation of total cholesterol (TC), triglycerides (TG), low-density lipoprotein (LDL-C), high-density lipoprotein (HDL-C), high-sensitivity C-reactive protein (hsCRP), fibrinogen and white blood cell counts (WBC). The periodontal parameters measured included bleeding on probing index (BoP), pocket depth (PD), clinical attachment level (CAL), the number of bleeding periodontal pockets (bPP) and the number of lost teeth. RESULTS Overall, patients shared high levels of periodontal inflammation and tissue breakdown. Multivariate analysis revealed a significant association between the serum concentration of LDL-C and bPP (standardized coefficient b = 0.3179; p = 0.0009) and PD (b = 0.3186; p = 0.0015); the level of fibrinogen and the number of lost teeth (b = 0.3669; p = 0.0013); WBC and bPP (b = 0.2726; p = 0.0035) independent of age, sex, income, education, atherosclerotic disease in the family, tobacco smoking, arterial hypertension, diabetes mellitus and BMI. No correlations were found regarding hsCRP serum concentration. CONCLUSIONS To our knowledge, this study demonstrated for the first time that local inflammatory processes in the oral cavity are positively associated with the systemic levels of LDL-C, fibrinogen and WBC in adult Poles. This may underscore relationships between periodontitis and MI as well as potentially impinge on atherosclerotic processes and MI prognosis.

Correlation between the state of periodontal tissues and selected risk factors for periodontitis and myocardial infarction

BACKGROUND The current level of knowledge indicates a relationship between periodontitis and diabetes and/or cardiovascular diseases (CVD). Periodontitis can be not only a risk factor for these diseases, but also a condition modifying other primary risk factors associated with the occurrence of cardiovascular complications (lipid disorders, arterial hypertension, etc.) or diabetes. OBJECTIVES The aim of the study was an analysis of the correlation between the state of periodontal tissues and selected risk factors for myocardial infarction (MI) in patients after recent myocardial infarction. MATERIAL AND METHODS The study included 417 patients (92 women, 325 men) hospitalized due to recent MI. The inclusion criteria were MI history and age below 70 years. The state of periodontal tissues (plaque index, bleeding on probing, pocket depth and clinical attachment loss, CPI index) and selected risk factors for periodontitis and CVD were recorded. RESULTS An analysis of the results showed no statistically significant correlation between the depth, the number, percentage of periodontal pockets and the average clinical attachment level on one hand and BMI on the other hand. Whereas a statistically significant correlation was observed between tobacco smoking and the degree of severity of periodontal diseases measured by the average pocket depth, the number and percentage of pockets above 4 mm and the average clinical attachment loss, as well as between hypertension and the state of oral hygiene and between diabetes and the number of preserved teeth and the number of pockets above 4 mm. CONCLUSIONS The degree of severity of periodontal disease can impact hypertension and diabetes, which could potentially influence the occurrence and course of CVD.

Oral health in postmenopausal and premenopausal women after myocardial infarction in Poland: a preliminary study

Introduction Age and hormonal disorders are recognized factors impacting the periodontium and the prevalence of cardiovascular diseases, but as yet the relationship between these two conditions in postmenopausal (post-M) and premenopausal (pre-M) women in Poland has not been assessed. The aim of this study was to compare the periodontal status in women after myocardial infarction (MI) with women without MI history and to determine risk factors for periodontitis. Material and methods The study included 35 women hospitalized due to MI, average age 54.7 ± 9.4 years, and 96 women randomly drawn from the general population, average age 56.1 ± 10.0 years. All women were checked for periodontitis risk factors (education, socioeconomic status, tobacco smoking, stress), and underwent dental examination. Results The lowest number of teeth was found in post-M women after MI (median = 8), whereas pre-M women without MI history had 25 teeth. Edentulousness occurred more frequently in post-M women compared with pre-M women (12.2% vs. 0%), the same was observed for advanced periodontitis (28.4% vs. 21.1%). The severity of periodontitis was highest in the post-M subgroup (more than half demonstrated advanced periodontitis or edentulousness). The most important risk factor for periodontitis, regardless of age, was the level of education. In post-M women the second risk factor was smoking, while in pre-M women negative stress. Conclusions The status of oral health in post-M women is unsatisfactory, particularly in those affected by cardiovascular diseases. It is necessary to take preventive and educational measures targeted at these women.
