The relationship between occlusion and periodontal health has been extensively studied. However, reports on the effects of passive eruption using occlusal reduction has not been sufficient. The purpose of the present randomized clinical trial was to assess the influence of passive eruption using occlusal reduction on the clinical periodontal parameters consisting of attachment level, pocket depth, tooth mobility, width of keratinized gingiva and osseous defect. The study was performed on 40 teeth of 16 subjects who have been treated for the moderate periodontitis at the Department of Periodontology, Pusan National University Hospital. At the baseline examination, after hygienic-phase and after 6 month from passive eruption using occlusal reduction, clinical parameters were monitored and radiographs were taken. The 20 teeth in the test group received passive eruption using occlusal reduction while the 20 control teeth did not receive any occlusal reduction. The results were as follows; 1) Degree of inflammation of periodontium was improved by initial therapy 2) Teeth received passive eruption using occlusal reduction demonstrated significantly greater reduction in pocket depth, tooth mobility and amount of bone loss, and increase in the width of keratinized gingiva, but no significant changes in the attachment level compared to the control teeth 3) There was significantly greater reduction in pocket depth, mobility, amount of bone loss and attachment level in the test teeth after initial hygienic phase when compared with baseline data. Taken together, these results suggest that the passive eruption using occlusal reduction would be helpful to improve periodontal health.

We investigated the gender-specific association between average volume of alcohol consumption, binge drinking, and periodontitis using representative nationwide data. In total, we included 3,549 men and 4,810 women, aged 19 years and older, who participated in the sixth Korea National Health and Nutrition Examination Survey performed in 2013~2014. According to the average volume of alcohol consumption, study participants were grouped as follows: mild drinkers (0.1~2.0 drinks/day in men and 0.1~1.0 drink/day in women), moderate drinkers (2.1~4.0 drinks/day in men and 1.1~2.0 drinks/day in women), and heavy drinkers (>4.0 drinks/day in men and >2.0 drinks/day in women). Additionally, binge drinking was categorized as never (no binge drinking), rarely (<1 time/month), occasionally (1 time/month), frequently (1 time/week), and always (almost every day/week). Periodontitis was defined as a community periodontal index equal to code 3 or greater. In men, after controlling for covariates, the association between average volume of alcohol consumption and periodontitis showed a J-shaped curve; the risk of periodontitis was significantly higher in moderate drinkers (odds ratio [OR], 1.25; 95% confidence interval [CI], 1.01~1.56) and heavy drinkers (OR, 1.39; 95% CI, 1.04~1.87) than in mild drinkers. In contrast, no significant association between average volume of alcohol consumption and periodontitis was observed in women. In a fully adjusted analysis, which used 'never binge drinking' as a reference, a significant dose-response relationship between binge drinking and periodontitis was observed only in men: rarely (OR, 1.64; 95% CI, 1.16~2.34), occasionally (OR, 1.51; 95% CI, 1.05~2.16), frequently (OR, 1.58; 95% CI, 1.07~2.33), and always (OR, 2.56; 95% CI, 1.56~4.22) (p for trend=0.005). In conclusion, unhealthy drinking patterns such as moderate or heavy alcohol consumption and binge drinking were significantly associated with periodontitis in men but not in women.

The purpose of this study was to examine the impact of the oral health behaviors and lifestyle of hypertension patients on their perceived periodontal diseases. The data of the 2013 community health survey were used, and the data of 55,632 patients who suffered from hypertension and who were at the ages of 19 and over was analyzed. The analying methods used in this study were chi-square test and multiple logistic regression analysis. Gender, age, marital status, education, economic activity, income level and subscription to private medical insurance were identified as the factors to affect the perceived periodontal disease of the hypertension patients, and lifestyle and oral health behaviors were found to have exerted a significant influence on perceived periodontal disease. As this study found that not only the socioeconomic characteristics of the hypertension patients but their oral health care and lifestyle were all correlated with perceived periodontal disease, how to promote the oral health of those who are susceptible to periodontal diseases should carefully be considered.

Background: The aim of this study was to examine the association between physical activity and periodontitis in the Korean population. Methods: This study utilized data from 9,191 participants of the Korea National Health and Nutrition Examination Survey. Periodontitis was defined as a CPI score of 3 or 4. Physical activity was assessed by the trained interviewer using the International Physical Activity Questionnaire-Short Form (IPAQ-SF). IPAQ-SF is composed of vigorous physical activity, moderate physical activity, and walking activity. Multivariable logistic regression analyses and stratified analyses by obesity were performed. All analyses were conducted separately for males and females. Results: Females who engaged in vigorous and moderate physical activity had a 28% (OR = 0.72, 95% CI = 0.54 - 0.95) and 34% (OR = 0.66, 95% CI = 0.44 - 0.98) lower risk of periodontitis, respectively. In obese females, moderate physical activity in obese had a 65% lower risk of periodontitis (OR = 0.35, 95% CI = 0.18 - 0.67). Conclusions: Our findings suggest that moderate-intensity physical activity was inversely associated with a lower risk of periodontitis. In obese females, moderate physical activity had an independent inverse association with periodontitis.

본 연구의 목적은 중국 연변조선족자치구에 현존하는 각종 유형의 도서관문헌 정보사업 현황과 문제점을 밝히는데 있다. 본 연구의 의의는 공개된 자료가 미미하고 정형화된 자료가 부족한 상황에서 실태조사를 병행하여 상세한 정보를 제공한 점이다. 도서관의 현대화작업은 90 년대 후반기부터 컴퓨터를 도입하여 전개되기 시작하였고, 연변과학기술대학도서관의 경우는 현대화된 시설을 갖추고 한국의 선진 도서관리 방법을 도입하여 도서관을 운영하고 있으나, 기타 도서관들은 부분적으로 전자 연람실을 구축하여 서비스하고 있다. 그러나 현재 조선족자치주 대부분의 도서관들은 자금부족으로 현대화된 도서관을 구축하지 못하고 있는 실정이다. 앞으로 지도층에서의 중점사업으로의 추진과 서부대개발사업의 우대정책을 통해 자금 확보를 도모하여 도서관의 현대화 건설의 추진을 기해야 할 것이다.

To investigate the necessity of periodontal treatments, and the association of the health lifestyle with periodontal treatments, the data of 11,488 adults targeted in the 5th (2010, 2012) National Health and Nutrition Examination Survey were used in this study. Chi-squared test was conducted to compare the subjects' general features with the health lifestyle of the patients who needed periodontal treatments. Logistic regression analyses were conducted to confirm the variables that could affect the necessity of periodontal treatments. As a result of verifying the necessity of periodontal treatments according to the general features and health lifestyle, the necessity decreased with the higher income level and education level, and in the cases of nonsmokers, frequent toothbrushing, and using oral hygiene products. When the subjects who did not had oral examinations, their necessity for periodontal treatments significantly increased (p<0.01). The variables that affected the necessity of periodontal treatments included residence, gender, education level, obesity, and oral examinations (p<0.01). Therefore, health lifestyle was thought an important variable that had affected the oral health status. Professional dental hygienists must provide people with action programs of health lifestyle to promote the national oral health status.
