유리 라디칼과 활성 산소종, 산화방지제 간의 불균형이 염증성 구강내 질환의 발생과 진행에 있어 중요한 역할을 한다는 주장이 제기되었고 최근에는 만성 염증성 치주질환에서도 산화에 의한 소실이 관찰되었다. 다양한 내적인 항산화 방어 기전 중 superoxide dismutase 가 $O_2$를 $H_2O_2$로 효과적으로 전환시킴으로써 활성산소종에 대한 일차적인 방어를 맡고 있다. 현재까지 인간에서 발견된 superoxide dismutase 는 cytoplasmic copper-zinc SOD와 mitochondrial manganase SOD, extracellular SOD의 3가지 아형이다. 이번 연구는 만성 치주질환을 가전 환자의 치주조직에서 효소 항산화제인 SOD의 발현정도를 알아봄으로써 질환조직 내의 산화자극 정도를 평가해 보고자하였다. 전남대학교 치주과에 내원한 33명의 만성 치주질환자와 20명 의 임상적으로 건강한 대상으로부터 조직을 얻어 Cu/Zn-SOD와 Mn-SOD, EC-SOD를 이용한 면역조직화학 염색을 시행하였다. 임상적 소견과 조직학적 소견이 일치하지 않아 조직학적 소견을 기준으로 건강한 조직, 경도, 중등도, 중도 치주질환 조직으로 그룹을 나누고 완전한 상피와 결합조직을 가진 27개의 표본에 대한 분석을 시행하였다. 치주질환 조직에서 건강한 조직에 비해 Cu/Zn-SOD가 상피의 기저층과 상피에 근접한 결합조직에서 발현되고 Mn-SOD는 염증이 증가함에 따라 크게 상피의 과립증과 각화층, 그리고 상피에 근접한 결합조직에서 발현됨으로써 활성산소종이 치주조직 파괴에 관여한다는 것을 알 수 있었다. 세 아형 모두 혈관주위에서 발현되었고 특히 EC-SOD는 작은 모세혈관주위에서만 발현되었으나 염증에 의해 혈관벽이 두꺼워지고 혈관 수가 증가한 곳에서 뚜렷하게 염색되었다. 이번 연구는 염증성 치주조직내 증가된 SOD의 활성이 치주질환자의 산화자극 정도와 관련되어 있음을 시사하였다.

The purpose of this study is to confirm the relevance between the frequency of beverage consumption and periodontal disease among Korean adults. The data used for analysis was obtained from the 6th Korea National Health and Nutrition Examination Survey (2013-2015). The subjects were 9,042 adults aged 19 to 64. In non-smoking group, people with periodontal disease had less intake of milk, carbonated beverage, and fruit juice and more intake of coffee than people without periodontal disease. In smoking group, people with periodontal disease had less intake of milk, liquid yogurt, carbonated beverage, and fruit juice and more intake of coffee than people without periodontal disease. In the results of verifying the correlation between periodontal disease and beverage intake in accordance with the matter of smoking after revising the socio demographic characteristics, in non-smoking group, the intake of coffee was correlated with periodontal disease. In smoking group, the intake of milk was correlated with periodontal disease. Since the intake frequency of some beverages is related to periodontal disease, there should be guidelines on beverage consumption during the periodontal disease prevention education.

There have recently been an increasing number of reports claiming that the periodontal disease, the most typical oral disease, is closely associated with various systemic diseases such as cardiovascular disease. Therefore, it is imperative to explore the methods that can ensure effective and cost-effective monitoring of periodontal disease in specific population groups, as well as individuals in the electronic medical record environment. However, traditional periodontal examination methods, such as periodontal probe, are considerably demanding and time-consuming for dental specialists, and furthermore, cause the risk of bacteremia as they are invasive procedures. Thus, the objective of this study was to validate the capability of new method for screening the periodontal disease using the self-reported questionnaire for periodontitis which is the non-invasive procedure to replace radiography.

There is little evidence on the effects of environmental tobacco smoke (ETS) on prevalence of periodontal disease. The aims of this study were to explore the trends of prevalence of periodontal disease and types of exposure to smoke, including ETS according to the survey year, identify factors affecting periodontal disease, and compare the effect size of periodontal disease between active smokers and secondhand smokers. Data on 11,643 individuals were obtained from the fourth and fifth Korean National Health and Nutritional Examination Surveys. Information on exposure to ETS at home and work was self-reported. Severity of periodontal disease was evaluated using the community periodontal index. A multivariate logistic regression analysis was performed to model periodontal disease using types of smoking and the survey year. Overall, the prevalence of periodontal disease was 26.0% (n=3,029) and about 9% of the study population were secondhand smokers. The prevalence of periodontal disease among smokers was significantly increased according to smoking types by year. Active smokers showed a statistically significant adjusted odds ratio (aOR) for having periodontal disease except in the year 2007, whereas secondhand smokers had significant associations only in 2010 (aOR, 1.68; 95% confidence interval, 1.05 to 2.70) compared to non-smokers. For secondhand smokers, the statistical relationship of predicting periodontal disease was weaker than that of active smokers. However, ETS should separately be considered as an important risk factor for periodontal disease. This study suggested the need for further investigation of the impact of ETS on prevalence of periodontal disease using in-depth research designs and objective measurements for assessing periodontal disease and ETS.

Objectives: This study investigated the relationship between the Korean healthy eating index (KHEI) and periodontal disease in the Korean adult population. Methods: The data used in the analyses were obtained from the seventh Korean National Health and Nutrition Examination Survey (2016-2018). Data were analyzed by chi-square tests and t-test. Multiple regression analysis was also performed to assess the association between KHEI and periodontal disease. Statistical significance was set at p<0.05. Results: Multiple logistic regression analysis adjusted for socioeconomic variables showed that medical and health behavior variables were significantly related to the KHEI 1 (<63.7, odds ratio [OR]: 1.23, 95% confidence interval [CI]: 1.03-1.46), KHEI 2 (63.7-79.9, OR: 1.14, 95% CI: 0.97-1.34), and risk for periodontal disease. Conclusions: The results showed a significant association between the KHEI and periodontal disease in the Korean adult population.

Objectives: This study was conducted to identify the relations between multiple chronic diseases and peridontal diseases in Korean adults. Methods: A total of 4,142 cases was set for analysis, who aged 35 and over and finished with the third year health survey and oral health check-up of the fifth Korea National Health and Nutrition Examination Survey(2012). Peridontal disease was defined if community periodontal index(CPI) was 3(formation of paradental cyst of more than 4mm) or 4(formation of paradental cyst of more than 6mm). Results: The subjects consisted of 48.5% male and 51.5% female. The prevalence rate of peridontal disease was found to be 30.1% in total. In peridontal disease the more the age increased, and the lower the education level and income level as well as the more where the residential area was rural, the higher the prevalence rate was(p<0.01). According to the number of multiple chronic conditions the prevalence rate of periodontal disease accounted for 27.8%, 31.9%, 33.1%, and 35.2% when there were 0, 1, 2, and 3 or more chronic diseases respectively. As a result of logistic regression analysis, gender, age, education level, residential area, current smoking, and use of oral hygienic products were found to be significant factors on peridontal disease. Conclusions: This research revealed the prevalence rate of peridontal disease was 30.1% in Korean adults and health behaviors affecting on periodontal disease were more significant.

The purpose of this study was to obtain basic data on the relationing between smoking, drinking and periodontal pocket formation. There was no nationwide epidemiologic study on periodontal diseases and smoking, drinking in korea. 177 adults aged 20 and older were recruited the study subjects. Data for smoking, drinking and general characteristics were collected by questions. Periodontal pocket formation was measured greater than 3 mm by probing. Sectional arch numbers of periodontal pocket formation by sex, marriage status and drink yes or no were no statististically difference. Sectional arch numbers of periodontal pocket formation by ages were statististically to increase in proportion to age. Sectional arch numbers of periodontal pocket formation by economic status were statististically to increase in proportion to high economic status. Sectional arch numbers of periodontal pocket formation by smoke yes or no were statististically to increase more smokers than non-smokers. According to regression analysis, periodontal pocket formation was influenced by age, economic status and smoke yes or no.
