Objectives. The aim of this study was to evaluate the association between metabolic syndrome and periodontitis in Korean adult population. Methods. We analyzed a total of 2,808 subjects aged 18 years or older who participated in a Korea National Health and Nutrition Examination Survey in 2007. Periodontal health was measured using Community Periodontal Index (CPI). Periodontitis was defined as CPI score was three or four. Metabolic syndrome (MS) was the diagnosis when participants were positive for three or more of five components of MS. The association between periodontitis and MS was analyzed using a χ2-test and logistic regression analysis (using SPSS 17.0). Results. The prevalence of periodontitis was higher among people who were male, older, and current or ex-smokers. People having periodontitis were likely to have lower household incomes, and do more frequent toothbrushing and drinking. Persons having MS had significantly higher odds of having periodontitis than normal people; the odds ratio was 1.23 after adjusting for age, gender, education, intake of alcohol, smoking, toothbrushing, oral hygiene goods, eating between meals, exercise and household income (95% CI: 1.02~1.47). Conclusions. Korean adults with MS had a higher risk of periodontitis. Further studies are required to investigate a casual relationship between MS and periodontitis.

Objectives. The purpose of this study was to analyze the relationship between the risk of newly developed dental caries and diet pattern among early adolescence for three years as a longitudinal design. Methods. A middle school in a city of Korea was conveniently selected for this study. An oral exam and a food frequency questionnaire (FFQ) were performed every year from 2007 (baseline) to 2010 (end point) among 244 middle school students who consented to this survey. All the collected data were analyzed using SPSS 17.0. Corresponding p-values were considered significant at values of less than 0.05. Results. With a greater protein and lipid consumption, a lower mean change of DMFT index was observed, but there were no statistically significant after adjusting the DMFT index at baseline. Among the essential minerals, the group that consumed less calcium, phosphorous, magnesium and fluoride were likely to have a higher increment of the DMFT index. In terms of microelements, for the early adolescents who consumed more copper and selenium, less change was revealed in the DMFT index over the three years, but there were no differences. Conclusions. This study may suggest that a greater carbohydrate intake tends to result in a higher DMFT increment. Further studies need to be implemented to investigate the causal relationship between minerals and microelements and dental care.

만성폐쇄성폐질환은 높은 유병률과 사망률임에도 불구하고 과소 진단되고 있는 질병이다. 이 연구에서는 국민건강영양조사를 이용하여 우리나라 성인을 대상으로 치주질환과 만성폐쇄성폐질환의 관련성을 파악하여 구강위생을 통한 치주건강을 향상시킴으로써 만성폐쇄성폐질환 악화를 예방하기 위한 기초자료를 마련하고자 하였으며, 다음과 같은 결론을 얻었다. 1. 연구대상자의 치주상태에 따른 분포에서 폐기능정상군에서 치석형성치주조직을 가진 대상자가 42.3%로 가장 높게 나타났으며, 천치주낭형성치주조직을 가진 대상자가 24.1%, 심치주낭형성치주조직을 가진 대상자가 6.3%로 나타났으며, 만성폐쇄 성폐질환군에서도 치석형성치주조직을 가진 대상자가 31.5%, 천치주낭형성치주조직을 가진 대상자가 28.8%, 심치주낭형성치주 조직을 가진 대상자가 13.3% 순으로 나타났다. 2. 로지스틱 회귀분석한 결과, 건전치주조직을 가진 대상자에 비해 천치주낭형성치주조직 대상자의 만성폐쇄성폐질환 위험비는 0.79배(95% CI=0.50, 1.25)로 나타났으며, 심치주낭형성치주조직 대상자의 만성폐쇄성폐질환 위험비는 1.18배(95% CI=0.63, 2.21)로 치주질환과 만성폐쇄성폐질환과는 관련성이 없는 것으로 나타났다. 3. 흡연상태를 층화시켜 분석한 결과, 심치주낭형성치주조직대상자의 만성폐쇄성폐질환을 가질 위험비는 흡연자에서 0.92배(95% CI=0.41, 2.05), 비흡연자에서 1.29배(95% CI=0.64, 2.59)로 나타났지만 통계적으로 유의하지 않았다. Objectives: The aim of this study was to examine the relationship between periodontal health and chronic obstructive pulmonary disease (COPD) in a Korean population. Methods: The Community Periodontal Index (CPI) data of 7,264 subjects, aged over 25 years, who participated in the Fourth Korea National Health and Nutrition Examination Survey was used to assess the periodontal status of the population. Severity of COPD in the subjects was classified according to the Global Initiative for Chronic Obstructive Lung Disease (GOLD) definition. Results: Subjects with more severe COPD were more likely to have severe periodontal disease. After adjustment for gender, age, monthly income, education, economic activity, and occupation, the odds ratio of COPD was 1.18 (95% Confidence interval [CI], 0.63-2.21) for severe periodontal disease in the study sample. When stratified by smoking status, the odds ratio of current smokers was 0.92 (95% CI, 0.41-2.05) and that of non-smokers was 1.29 (95% CI, 0.64-2.59). Conclusions: Periodontal health was not significantly related to the severity of the COPD, even though smoking was a common risk factor. This is the first study examining the relationship between periodontal health and COPD in a Korean population. Studies that further investigate the causal relationship between the two are recommended.

Objectives. Metabolic syndrome (MS) is becoming a common disorder worldwide. Preventing metabolic syndrome is important because the presence of multiple MS components increases the risk of developing cardiovascular diseases. In this cross-sectional study, we aimed to assess the association of between MS and gingivitis in youth. Methods. A total of 947 subjects (513 boys and 432 girls) who underwent medical and dental checkups with all MS components was final sample size from data analysis from the fourth Korea National Health and Nutrition Examination Survey. We examined the relationship between each component and the number of positive components of MS (central obesity, hypertriglyceridemia, low high-density lipoprotein-cholesterol, hypertension, insulin resistance) and gingivitis status using the Community Periodontal Index. The logistic regression models were build odds ratios (ORs) and 95% confidence intervals (CIs) were calculation using SPSS 17.0 program. Results. Of the five components of MS, low HDL cholesterol level and high blood pressure were each significantly related with having gingivitis. Logistic regression analysis for full model including all metabolic syndrome components and other risk factors the OR for low HDL-cholesterol was 1.52 significantly and the OR for high blood pressure was 1.38. Conclusions. Gingivitis was positively associated with MS in Korean, suggesting that further studies should be needed to investigate causal relationship.

Objectives: This pilot study aimed to evaluate the effect of dental amalgam, a restorative material, on children by measuring the mercury concentration in the urine as well as the number of teeth filled with dental amalgam. Methods: Twenty children enrolled in grades 1-4 of two elementary schools in Daegu participated in this study. One trained dentist performed oral examinations and removed amalgam restorations from the teeth with a high and low speed handpiece. In order to measure the urinary mercury concentrations, urine samples were collected from all participants at baseline and immediately and 24 hours after removal of the dental amalgam restorations. Results: The mean number of teeth from which the amalgam restorations was removed was 9.8 while the mean urinary mercury concentrations at baseline, immediately, and 24 hours after removal of dental amalgam restorations were 2.66, 2.76, and 2.76 μg/g creatinine, respectively. The mean urinary mercury concentration increased consistently after amalgam restoration removal. For those participants whose removed amalgamated surfaces were more than 11, the mean urinary mercury concentration immediately after amalgam restoration removal and 24 hours after removal increased consistently but showed no significant difference. Conclusions: This study demonstrated that dental amalgam restoration was related to urinary mercury concentration, and these findings present a possibility of mercury accumulation in the body. Therefore, we suggest future longitudinal studies to ensure the safety of children exposed to mercury by establishing criteria for amalgam removal.

Objectives: The capacity of dental clinicians to assess oral health and to advocate for dental care has been hampered by limitations for measuring the quality of life and/or satisfaction with implant treatment. The use of patient-based outcomes to measure the effectiveness of treatment is increasing as clinical scientists attempt to evaluate the impact of therapy on the recipient. The purpose of this study was to assess the change of oral health related quality of life between pre- and post-treatment with implant therapy. Methods: Two hundreds and forty-six consecutive patients from six private dental clinics in Daegu, Korea participated with consent in the survey of this study, and we obtained the patients` consent. The oral health related quality of life was measured by OHIP-14 before implant therapy and six months after all the implant therapy was finished. All the statistical analyses were performed using SPSS(SPSS 14.0 for Windows, SPSS Inc, USA). Results: The oral health quality of life was significantly increased after implant therapy for all the subscales of OHIP-14 (p<0.001). Psychological discomfort and physical disability factors were decreased most significantly among 7 subscales, when compared between pre- and post-treatment. The OHIP-total score was significantly raised from 54.78 (pre-treatment) to 64.90 (post-treatment) following implant therapy (p<0.001). The more implants a patient received, the more increased was the score of all the subscales of the OHIP-14 (p<0.001). Conclusion: Implant therapy can improve the oral health related quality of life among dental patients. It can also stimulate the satisfaction for the general quality of life.

박지혜(Park, Ji-Hye),안상헌(Ahn, Sang-Hun),구효진(Gu, Hyo-Jin),최연희(Choi, Youn-Hee),송근배(Song, Keun-Bae) 한국산학기술학회 2010 한국산학기술학회논문지 Vol.11 No.1

본 연구는 임신 및 수유기간 동안 구강위생상태가 불량해질 수 있는 임산부에 있어서 장기간의 자일리톨 섭 취가 Streptococcus mutans(S. mutans) 집락수에 어떠한 영향을 미치는 지에 대해 알아보고자 하였다. 임산부구강건강 예방프로그램에 대상자를 자발적으로 모집하여 두 군(실험군과 대조군)으로 나눈 후 18개월간 추적 조사하였다. 자극 성 타액은 오후시간(1:00-3:00 p.m.)에 초기, 6개월, 12개월 및 18개월에 채취하였다. 구강보건행태(잇솔질 횟수와 정기 구강검진)에 관한 정보는 설문지를 통해서 얻어졌다. 타액 내 자일리톨군의 연구기간에 따른 S. mutans 평균집락수의 차이는 통계적으로 유의하였으며, 특히 연구초기에 비해 출산 후 6개월, 12개월 및 18개월 모두에서 유의한 감소를 나타내었다. 반면 대조군에서는 연구초기에 비해 출산 후 18개월에서만 유의한 감소를 나타내었다. 이상의 결과를 종 합해 보면, 자일리톨의 장기적인 섭취는 구강 내 S. mutans 집락수를 감소시킴으로써 임산부들에 있어서도 치아우식 증 예방효과가 나타날 수 있을 것으로 사료된다. The purpose of this study was to evaluate suppression of Streptococcus mutans(S. mutans) colonization by long-term xylitol consumption among pregnant women who can easily get bad oral hygiene status during pregnancy and breast feeding. Participants were voluntarily recruited for a pregnant women's oral health prevention program, classified into two groups(a control and a xylitol group), and then followed for 18 months. Stimulated whole saliva was collected in the afternoon(1:00-3:00 p.m.) at baseline, 6 months, 12months, and 18 months. Information regarding oral health behavior(tooth brushing frequency and regular dental visits) was obtained via a questionnaire. S. mutans counts of the xylitol group decreased considerably between baseline and the re-examinations at 6, 12, and 18 months. Although the S. mutans counts decreased for all time points compared to baseline in the control group, these differences did not reach significance except 18 months. Regular chewing of xylitol gum over a long period may lead to decrease the colony counts of S. mutans.
