Objectives: The purpose of this study was to compare the oral health statuses pre- and post-insurance using the $5^{th}$ and $6^{th}$ National Health and Nutrition Examination Survey data to confirm the effect of scaling insurance after a year. Methods: Data were analyzed using IBM SPSS ver. 21.0 (IBM Co., Armonk, NY, USA). The four years were integrated, and a composite sample analysis was performed. A total of 26,990 people were included in the study before applying for scaling insurance (14,343 persons) or after receiving scaling insurance (12,647 persons). A chi-squared test was performed to compare the demographic characteristics and oral health status of the subjects. The significance level of the statistical test was 0.05. Results: The proportion of patients without implants was high before the provision of scaling insurance once a year, however, the proportion of patients with one or more implants was high (p<0.05) after the provision of scaling insurance once a year. Hemorrhagic periodontal tissues and tartar formation in periodontal tissues were highly prevalent before the provision of scaling insurance once a year, however, healthy periodontal tissues and formation of periodontal pockets were highly prevalent (p<0.05) after the provision of scaling insurance once a year. The decay, missing, and filled teeth index scores were higher before the provision of scaling insurance once a year (p<0.05). Conclusions: The aforementioned results showed that scaling once a year helps prevent or treat periodontal disease. In addition, we confirmed the effect of prevention on periodontal disease and dental caries, therefore, we expect it to develop into a stable policy.

Objectives: We sought to evaluate the mitigating effect of using floss and interdental brushes on periodontal health inequality. Methods: This study was based on data acquired from the Seventh Korea National Health and Nutrition Examination Survey (KNHANES VII; 2016-2018). We included 11,359 participants aged ≥19 years in the final analysis. Multivariable logistic regression analysis was performed using socioeconomic characteristics, health behavior, health status, and periodontitis status. We analyzed differences in the prevalence of periodontitis according to household income stratified by the use of floss and interdental brush. Results: In the multivariable logistic regression model, the lowest income group had 1.304 (95% confidence interval [CI] 1.08-1.58) odds ratios for periodontitis than the highest income group. In the interdental brush nonusers or floss nonusers, the lowest income group had significantly higher odds of developing periodontitis. However, we found no significant differences in the periodontitis prevalence between the income groups among the interdental brush users. In the 65-year-old or older group, the same result was observed in the interdental brush and floss users. Conclusions: The results suggest that the use of floss and interdental brushes could alleviate periodontal health inequality.

Objectives: The aim of this study was to investigate the effects of periodontal disease in menopausal women. Methods: We used data from the 7th (2016-2018) Korea National Health and Nutrition Examination Survey. The subjects of the study were 2,643 women aged 40 to 59 years who participated in the periodontal examination and answered a menses questionnaire. The data were analyzed using complex samples multivariate logistic regression to investigate the effects related to periodontal disease in menopausal women. Results: After adjusting for general characteristics, oral health behaviors, and health status, those aged 50-59 years had odds ratio (OR) for periodontal disease of 2.52 compared to those aged 40-49 years. Compared to those who brushed 3 or more times a day, those with less than 3 brushings a day had OR of 1.48. Those who smoked had a 3.00 higher risk of periodontal disease than those who were non-smokers. Further, those with glycosuria had a 2.26 higher risk of periodontal disease than those without glycosuria. Conclusions: In order to promote the oral health of menopausal women, it is suggested that comprehensive and systematic oral health education should be implemented considering various variables.

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.

Objectives : The purpose of this study was to analyze the status of oral health in relation to the acknowledgement of oral health trouble and oral health habits. Methods : This study was conducted after IRB was received, on 273 patients who had received health screenings between October-1, 2014 and January-31, 2015 at a general hospital in Busan. Results : Regarding the status of oral health in relation to the acknowledgement of oral health trouble, the rates of dental caries and periodontal disease were higher when the patients knew the reasons for trouble about the oral hygiene. With regard to oral health habits, our results showed that the more frequently the patients ate sugary snacks per day, the probability of experiencing periodontal disease was higher than for the patients who did not eat sugary snacks. Our results also, showed that the occurrence of dental caries is very much dependent upon whether a patient had experienced education on toothbrushing. Conclusions : Patients need to become more aware of their oral health through education. A program that emphasizes the importance of preventive oral health behaviors and the maintenance of correct oral health behavior should be developed.

Objectives: The purpose of the study was to investigate the relationship between the oral contraceptive pill and periodontal disease in Korean women aged from 19 to 50 years old. Methods: This study selected 1,579 women of childbearing age from 19 to 50 years old from the 5th National Health and Nutrition Survey data analysis(phase 3, 2012) taking the oral examination. The questionnaire consisted of socioeconomic demographic characteristics, health behavior, use of oral contraceptive pills, and periodontal disease. Socioeconomic demographic characteristics included age, marital status, education, monthly income, and vocation. The health behavior included obesity, stress, smoking, subjective oral health status, use of dental floss, tooth brushing, and diabetes mellitus by fasting blood sugar level. Use of oral contraceptive pills was recorded by monthly use and duration. The periodontal disease was documented by yes or no and selected as dependent variable by logistic regression analysis. Results: After revising the taking period of oral contraceptive pill for this study, there was the correlation between the prevalence of periodontal disease and odds ratio(95% CI) 1.288(1.027-1.617). Conclusions: This study will contribute to the direction of policy for an oral contraceptive pill and provide the basic data for counseling for the oral health and the side effects of oral contraceptive pills.

Objectives : The purpose of this study was to examine the oral health behavior of shipbuilding company workers in some regions in a bid to provide information on the oral health plans for industrial fields. Methods : The subjects in this study were 310 workers in 10 shipbuilding companies and suppliers in Jeolla Namdo Province, on whom a self-administered survey was conducted. Results : 1. Concerning general information about the subjects who participated in the research, gender was possessed 94.8% by men and 5.2% by women. Age was the largest in 31~40 years old with 44.2%. Marital status was the largest in the married with 64.5%. It was the largest in under high school graduate with 71.9% for academic background, in 2,000,000 won~3,000,000 won with 49.0% for monthly family income, and in cooking with 33.9% for work field. 2. Research subjects' toothbrushing time was indicated to be the largest in after having breakfast. It was indicated to be twice a day with 41.3% for toothbrushing frequency. 90.3% of the respondents are not using auxiliary oral hygiene devices. 3. Recognition on periodontal health status was found larger in workers whose response was that their own periodontal health status is 'healthy' than workers who responded that their status is 'not healthy.' Workers, who don't have subjective symptom on periodontal status, were indicated to be larger. 4. Ratio of subjects with tooth scaling experience accounted for 59.7%. The ratio of tooth scaling experience was indicated to be different depending on academic background and monthly family income. Conclusions : Academic credential, monthly family income and the line of work were identified as the main factors to affect oral health care of the shipbuilding workers. Oral health education and dynamic implementation of corporate oral health promotion which are designed to meet the needs of workers are required.

In this study, 110 adults aged 40 to 69 years were surveyed from April 28, 2016, to May 28, 2016 to analyze their periodontal status according to daily stress, coping methods, and oral health behavior. The collected data were analyzed using the t-test, one-way analysis of variance, and hierarchical multiple regression. Daily stress levels of all subjects were most frequent potential risk 64.5% of the subjects, the high risk 19.1% and 16.4% of the health group. Regarding stress coping methods, active methods recorded 2.46, passive methods recorded 2.32. Regarding oral health behaviors, subjects brushed an average of 2.45 times daily, for an average of 2 minutes. Futhermore, 69.1% of subjects brushed before bedtime and 89.1% practiced scaling. Regarding periodontal status, the O'Leary index was 73.45, gingivitis index was 1.30, an average of 2.83 quadrants possessed a periodontal pocket. The hierarchical multiple regression analysis identified, type of employment (${\beta}=-0.348$), scaling (${\beta}=-0.253$), and age (${\beta}=0.244$) as factors that influence the number of quadrants possessing a periodontal pocket. These results confirmed that the oral health behavior of scaling, but not stress levels of coping methods, strongly influenced periodontal status.

Korea has been running the community oral health program for the elderly, including topical fluoride application and scaling. The aim of this study was to compare the subjective and objective oral health status of 345 participants according to the number of participants in the program and of 37 participants before and after the 5-year program. The survey consisted of an interview questionnaire and oral examinations. Analysis of variance was used to compare the variables of the 345 participants according to the numbers of participants. Paired t-test was used to compare the oral health statuses before and after the 5-year program in 37 subjects. There was no difference in subjective oral health status according to the number of participants in the oral health program in the elderly, including subjective health status, subjective oral health status, satisfaction with oral health, concern about oral health, need of dental treatment, oral pain, tooth sensitivity, subjective periodontal health, and subjective symptoms of periodontitis. The community periodontal index (CPI) of the 1 time participants was significantly higher than that of 3 times, 4 times or 5 times participants in the upper center, lower left, lower center, and lower right areas. There was a significant improvement in CPI from $2.59{\pm}1.14$ to $1.41{\pm}1.54$ (p<0.001) and positive oral behavioral change (daily tooth brushing frequency from $2.27{\pm}0.73$ to $2.54{\pm}0.90$) before and 5 years after the program. However, the program did not prevent tooth loss as the numbers of the remaining teeth significantly reduced from $23.77{\pm}1.84$ to $21.95{\pm}2.03$ over 5 years. We showed that running the community oral health program for the elderly for more than three years might have positive effects on the periodontal health of participants.

Objectives: The aim of this study was to evaluate the oral health status and behavior in Korean diabetic adults. Methods: The study subjects were 11,840 adults who participated in the fifth Korea National Health and Nutrition Examination Survey(2010-2012). Diabetic status was defined by doctors and fasting blood sugar(FBS) level. Oral health status was assessed by decayed-missing-filled teeth(DMFT), community periodontal index(CPI), periodontal disease, denture needs, limitation of oral function, and chewing difficulty. The oral health behavior was evaluated by oral examination within a year, brushing times a day, and use of auxiliary oral product. The data were analyzed by descriptive analysis, chi-square tests and multiple logistic regression analyses. Results: The prevalence rate of diabetes mellitus diagnosed by doctor and FBS was 8.3% and 10.2%, respectively. The prevalence rate of periodontitis was 25.4%. The proportions of $DMFT{\geq}20$, $CPI{\geq}3$, periodontal disease, denture needs, oral function limitation and chewing difficulty in the confirmed diabetic group by doctor were significantly higher than those of the non-diabetic group(p<0.05). In multiple logistic regression analysis, the adjusted odds ratio(aOR) for periodontal disease(aOR=1.73, 95% CI=1.41-2.12), presence of denture needs(aOR=1.40, 95% CI=1.06-1.84), limited oral function(aOR=1.43, 95% CI=1.15-1.78) and chewing difficulty(aOR=1.41 95% CI=1.13-1.77) in diabetic subjects were significantly higher than those of the non-diabetic subjects. There were similar associations between diabetes defined with FBS and oral health. In oral health behavior, diabetic subjects had significantly lower odds ratios for oral examination(aOR=0.76, 95% CI=0.60-0.98), brushing time ${\geq}2$ times(aOR=0.73, 95% CI=0.57-0.93), and auxiliary oral products(aOR=0.74, 95% CI=0.59-0.94). Conclusions: There was a significant relationship between oral health status and behavior in Korean diabetic adults. Further study is needed to evaluate the underlying mechanisms between diabetes mellitus and oral health status.
