Results: There were no statistically significant changes in HbA1c levels in the IC and MC or their subgroups when evaluated with repeated-measures analysis of variance. However, the IC showed maintenance of baseline HbA1c levels, while the MC had a trend for HbA1c levels to steadily increase as shown by pairwise comparisons (baseline to 6 months and baseline to 12 months). IC subgroup 1 also maintained steady HbA1c levels from 6 months to 12 months, whereas MC subgroup 1 presented a steady increase during the same period. The number ofperiodontal maintenance visits had no association with changes in HbA1c levels during the 1-year study duration.
experiments in diabetic rats. However, the bone healing disturbances analyzed in these studies may not be manifested until a certain period of time has elapsed following diabetes induction. Therefore, the use of rats with unstandardized diabetesduration may create inconsistencies in experimental results, and it is therefore quite important to determine thediabetesduration when bone healing disturbances clearly appear. The purpose of this study was to determine the critical diabetesduration in a STZ-induced diabetic rat calvarial defect model for experimentation regarding bone regeneration by evaluating theassociationbetweendiabetesdurationand bone healing capacity through histological and radiographic analyses using cone-beam computed tomography (CBCT).
According to multivariate logistic regression analysis, the OR of carotid atherosclerosis according to the quartiles of thigh circumference were showed in Table 5.
However, theassociationof quartiles of calf circumference with carotid atherosclerosis was not significant (data not shown). The OR for carotid atherosclerosis increased according to the decreased thigh circumference based on an unadjusted model. Adjustments for age, durationofdiabetes, smoking status, BMI, blood pressure, lipid, kitt, WC, VAT and treatment medications, theassociationbetween carotid atherosclerosis and thigh circumference remained significant. The results of regression analysis indicated that thigh circumference was independently cor- related with insulin resistance and carotid atherosclerosis.

This paper reviews a current view regarding theassociationbetween periodontitis and atherosclerotic cardiovascular diseases (ACVD). Many evidences have suggested that there exist biological mechanisms by which periodontitis can lead to ACVD.
Periodontal infection can lead to direct bacterial invasion into endothelial tissues through the blood stream, then the bacteria can activate the host inflammatory response followed by atheroma formation, maturation and exacerbation. Also, chronic periodontal infections may indirectly induce endothelial activation or dysfunction through a state of systemic inflammation as evidenced by elevated plasma acute proteins, IL-6 and fibrinogen as well. There is moderate evidence that periodontal treatment can reduce systemic inflammation and improvement of both clinical surrogate markers. But there is no periodontal intervention study available on primary ACVD prevention. There is consistent and strong epidemiologic evidence, including in vitro, animal and clinical studies, that periodontitis imparts increased risk for future ACVD. However, evidences from intervention trials to date are not sufficient to confirm the multi directional causality of periodontitis in ACVD etiology. Well-designed intervention trials on the impact ofperiodontal treatment on the prevention of ACVD outcomes are needed.
however, the goal of this observational study was to determine whether a causal relationship is plausible. We found that as age increased, the prevalence of MetS (Table 1) andperiodontal disease severity (data not shown) increased. LXA4 levels may be affected by the synergistic effect of MetS andperiodontal disease. In order to characterize the relationships among periodontal parameters, MetS, and LXA4 as precisely as possible, the effects of possible confounders such as age and BMI were adjusted via various regression models. However, the effects of drugs such as statins, durationofthe disease, the number of MetS risk factors, and menopausal status, all of which may have affected the study results, were not evaluated. The mild to moderate periodontal status ofthe patients limited our ability to comment on the effects ofperiodontal disease severity on MetS and LXA4 levels.
In the initiation and progression of atherosclerosis, activated macrophages take up lipids and then these lipid-rich macrophages secret inflammatory mediators that stimulate VSMC migration and proliferation [15], resulting in atherosclerosis. It is known that YKL-40 is secreted by activated macrophages and neutrophils in different tissues with inflammation, vascular smooth muscle cells (VSMC), cancer cells, and arthritic chon- drocytes [16]. In this regard, YKL-40 may be involved in the early stage of atherosclerosis and CAD. So we cate- gorized the asymptomatic type 2 diabetic patients into two groups – those with any degree of stenosis in coron- ary artery on cCTA (suspected CAD) and those with completely normal coronary artery on cCTA (no evi- dence of CAD). In our study, we did not find any signifi- cant associationbetween suspected CAD and hsCRP, the most widely used and evaluated inflammatory biomarker for cardiovascular diseases. YKL-40 levels, however, were significantly higher in patients with suspected CAD than those with no evidence of CAD. YKL-40 is produced lo- cally by inflammatory cells, however, hsCRP is produced by hepatocyte in response to high circulating cytokine levels. Taken together, YKL-40 might be more sensitive marker than hsCRP for predicting suspected CAD in type 2 diabetic patients. Because few studies have been conducted on YKL-40 as a novel marker for predicting occult CAD in asymptomatic subjects with normal glu- cose tolerance or diabetes mellitus, our results make a novel contribution to the clinical relevance of YKL-40 in asymptomatic type 2 diabetic patients.

In view of these relations betweendiabetes mellitus andperiodontal disease, it has been speculated that treatment ofperiodontaldiseases can improve metabolic control of dia- betes. 18 According to previous studies, 19,20 the magnitude ofthe reduction in HbA1c ranged from 0.27% to 0.48% 3 - 4 months after periodontal treatment. Despite periodontal treatment seeming to ameliorate metabolic control, evidence was not sufficient to significant associate periodontal treat- ment and metabolic control in patients with diabetes. 21 According to a consensus report, there is a lack of data to manifest that this effect is maintained over 6 months fol- lowing periodontal treatment. 22
All the patients with ONFH or traumatic femoral neck fracture were diagnosed independently by two orthope- dists and pathologist. The synovial tissues were provided by The Keimyung Human Bio-resource Bank in Korea, which were frozen in liquid nitrogen and stored at − 80 °C. Patients with severe chronic diseases, such as cancer, cardiovascular diseases, immunodeficiency virus infection, diabetes mellitus, and renal dysfunction were excluded.
The present study could not elucidate the direct causal relationship between dietary quality andperiodontaldiseases. Despite this limitation, the study is meaningful as it used a more comprehensive approach than the traditional approach of assessing the impact of individual nutrients or food products on diseases to assess the risk ofperiodontaldiseasesand dietary quality. A longitudinal study on dietary quality andperiodontaldiseases is warranted. In conclusion, this study identified an associationbetween dietary quality andperiodontaldiseasesand found that poor dietary quality was significantly associated with an increased risk ofperiodontaldiseases.

Abstract Periodontal disease is a common inflammatory disorder that is being considered as a risk factor for atherosclerotic complication. Recent epidemiological evidence also supports that its potential association with increased blood pressure levels and hypertensive prevalence. Data from cross-sectional studies suggest that in hypertensive patients periodontal disease may enhance the risk and degree of target organ damage. So dental infections have been associated with cardiovascular diseases. There are potential pathophysiologic links between hypertension and periodontits. The role ofthe inflammatory pathway includes C-reactive protein(CRP). CRP is an inflammatory mediator that has been shown to predict the development of hypertension independently of baseline BP and traditional risk factors, has been consistently reported as at least mildly elevated in patients with periodontal disease.

Abstract This study aimed to identify theassociationbetween each stage of Community periodontal index of treatment needs (CPITN) and oral health behaviors. Multivariate logistic regression analysis was performed on the data obtained from 11,002 adults aged between 19 and 79 years, using data from the 7th Korea National Health and Nutrition Examination Survey. When interdental care products such as floss or interdental brush were used, the risk of CPITN1 to CPITN3 and periodontitis was significantly reduced. Brushing more than 3 times a day significantly reduced the risk for CPITN1 and CPITN2, and dental check-ups reduced the risk for CPITN1, CPITN2, and periodontitis. There were differences in related factors depending on the stage of CPITN and periodontitis. Therefore, it is essential to include training on the use of interdental care products in oral health education. In addition, it will be helpful educate subjects on select oral health behaviors based on their periodontal status.

ABSTRACT
Objectives: The objective ofthe study was to review the correlation between self-perceived oral health status andperiodontaldiseases in elderly Koreans, using data from the 6 th (2nd year) Korea National Health and Nutrition Examination Survey (2014). Methods: The subjects for this study were a total of 1,454 elderly people aged 65 years or older who responded to the health questionnaires ofthe 6 th (2nd year) Korea National Health and Nutrition Examination Survey conducted in 2014. Their general characteristics were analyzed using frequency analysis, while a cross-tabulation analysis ( 2 -test) was performed to understand the correlation with periodontaldiseases. To clarify any effect of self-perceived oral health status on periodontaldiseases, the selected variables were controlled and subsequently analyzed according to the logistic regression analysis. Results: In terms ofthe difference between elderly people with periodontal disease and those without periodontal disease, higher prevalence rates ofperiodontaldiseases were found in women, those of younger age, those with lower educational and income levels, those with poorer subjective oral health status, those in the presence of chewing discomfort, those who had a toothbrushing frequency of twice per day, and/or those who had received no oral examination over the previous one year. Regarding the effect of self-perceived oral health status on periodontaldiseases, 1.78-fold and 1.74-fold higher prevalence rates ofperiodontaldiseases were shown with poorer subjective oral health status and in the presence of chewing discomfort, respectively. Conclusions: Based upon the results above, it is considered that a better understanding of self-perceived oral health status is necessary for a healthy life ofthe elderly. Furthermore, constant relevant studies and effective prevention programs intended to moderate the progress of or prevent periodontaldiseases in the elderly in communities should be performed and implemented for the sake of better quality of life and oral health.
