Objectives: This study aimed to evaluate the relationship between pit and fissure sealants of the molars, and caries prevalence and experience to assess the effect of sealants on caries prevention. Methods: Data from 16,119 people were extracted from the seventh Korean national health and nutrition examination survey, which was conducted from 2016 to 2018. Demographic, socioeconomic, oral health-related behavioral, and oral examination survey data were collected as independent variables. SAS statistics for complex samples and multiple logistic regression analysis (Windows ver. 9.4) was used for the statistical analyses. Results: Caries prevalence and experience were significantly associated with age, sex, daily toothbrushing frequency, interdental cleaning, and having molar sealant. Multiple logistic regression analysis revealed a significant association between having molar sealants and the caries prevalence and experience among participants under 30 years of age after adjusting socio-economic variables and toothbrushing-related factors. Conclusions: This study confirmed the effect of molar sealants on caries prevention in Korea. Our results support that the application of molar sealants in children, adolescents, and young individuals is effective in preventing caries.

Stroke is the second cause of death worldwide, although the survival period is increasing after the occurrence of stroke, severe physical disability is caused with aftereffect. Oral inflammation is not limited to the oral cavity, it can cause malignant changes in other tissues and organs. In previous studies, we confirmed the relationship between tooth loss and stroke due to periodontal inflammation. The purpose of this study was to investigate the relationship between oral health and stroke such as oral hygiene behavior, tooth loss and periodontal disease among Korean adults over 40 years of age. This study was analyzed using the 6th Korea National Health and Nutrition Examination Survey (KNHANES) data. A total of 3,389 adults over 40 years of age were analyzed as final subjects. Socioeconomic statuses and oral health status was analyzed using a complex sample analysis technique. Logistic regression was used to analyze the relationship of oral health and stroke, and 95% confidence intervals were computed using SPSS. When the prevalence of stroke according to oral hygiene behavior was checked, the prevalence of strokes was lower in subjects who had a lot of brushings per day and subjects who used oral hygiene products (p<0.05). The risk of stroke was 2.17 times (95% confidence interval, 1.43~3.28) higher in the group with less than 19 remaining teeth, but it was not statistically significant as a result of adjusting for age and sex, income level, education level, drinking and smoking (p>0.05). Loss of teeth was found to be associated with the risk factor of stroke. Therefore, loss of teeth due to periodontal disease is an additional issue that should be considered as a risk factor for stroke.

Objectives: Dental caries and periodontitis are major oral bacterial infections associated with dental plaque. Infection and inflammation play a role in carcinogenesis, and a significant link has been found between some highly prevalent oral and dental diseases and some types of cancer. Therefore, the aim of this study was to evaluate the relationship between cancer and oral health among Korean adults. Methods: Data from the 6th Korea National Health and Nutrition Examination Survey were used to analyze the incidence of cancer according to oral health. Demographic and socioeconomic statuses and oral behavior of the participants was analyzed using complex chi-square tests. Logistic regression was used to analyze the relationship between a high DMFT index and cancer by calculating the 95% confidence intervals. Results: In total, 6,450 case-control subjects were included. Significant difference was observed in the DMFT index, but not in periodontal diseases, between the cases and controls. The odds ratio for cancer was 1.80 (95% confidence interval: 1.18 to 2.73) in the high-risk group. However, no significant difference was observed after adjusting for age, education level, and income. Conclusions: The results provide potential evidence of a significant association between cancer and oral disease.

Purpose: This study identified socioeconomic factors affecting the health status of Korean adults. Methods: Secondary data from 12,921 adults aged 19 to 64 old in the 7th Korean National Health and Nutrition Examination Survey were used. The participants' health status was measured using the indicators that included health behaviors (smoking, high-risk drinking, strength exercise, and aerobic physical activity) and health outcomes (metabolic syndrome, and subjective health status). Results: For all health behaviors and health outcomes, gender, age, educational level, and income were common affecting factors. Regarding health behaviors, the employment status was related to smoking, high-risk drinking, strength exercise, and aerobic physical activity. The marital status was related to high-risk drinking, strength exercise, and aerobic physical activity. The household type was related to smoking. The residential area was related to smoking, high-risk drinking, and aerobic physical activity. For health outcomes, the household type was related to obesity, and subjective health status; residential area was related to obesity. Conclusion: This study presented basic data for assessing the differences in health status. The characteristics of the affecting factors to health status should be considered, depending on the health behaviors and health outcomes.

Objectives: This study aimed to understand the effect of factors, possibilities, and desires on oral examination experience behavior of the elderly using raw data from the 2017 Community Health Survey. Methods: Hierarchical logistic regression analysis, an analysis method that controls the input order of a series of independent variables, was performed for 67,835 senior citizens aged 65 and older. Results: In terms of predisposing factors-in women, the higher the level of education, the higher the oral examination practice rate, and the lower the oral examination practice rate in divorce and bereavement among those aged 75 years or older. Regarding enabling factors, the lower the income rating, the higher the oral examination experience rate in religious and social participants as well as, leisure and charity participants, and the lower the oral examination experience rate in the natural environment. Regarding the need factors, the oral examination practice rate was high when the subjective oral health level was recognized as good. Conclusions: As a result, Anderson's model confirmed that various factors affect oral examination experience behavior, and institutional support for policy consensus is needed to promote oral examination experience behavior in older people in various directions.

Although the Korea National Health and Nutrition Examination Survey (KNHANES) calculates oral health functional restriction rate and chewing discomfort rate every year, these two indicators are not all indicators of oral health. Therefore, indicators are needed to subdivide by age group and cover dental caries, periodontal disease, remaining teeth, and oral care use. The purpose of this study is to identify the key indicators of oral health in mature and middle age. The average number of existing natural teeth, the rates of 20 or more natural teeth, complaints of chewing discomfort, oral examination, periodontal disease and dental caries, were analyzed using KNHANES VI (2013-2015) as a complex sample. In the age group between 40 and 64, there were 25.2 natural teeth remaining, 91.4% natural teeth retention rate, 23% chewing discomfort rate, 34.7% oral examination rate, 38.7% periodontal disease prevalence, 6.46 the number of caries experience teeth, 21.4% interdental brush usage rate.

Objectives: The purpose of this study is to examine and explain the extent of income-related inequity in health care utilization and expenditures to compare the extent in 2005 and 2010 in Korea. Methods: We employed the concentration indices and the horizontal inequity index proposed by Wagstaff and van Doorslaer based on one- and two-part models. This study was conducted using data from the 2005 and 2010 Korean National Health and Nutrition Examination Survey. We examined health care utilization and expenditures for different types of health care providers, including health centers, physician clinics, hospitals, general hospitals, dental care, and licensed traditional medical practitioners. Results: The results show the equitable distribution of overall health care utilization with pro-poor tendencies and modest pro-rich inequity in the amount of medical expenditures in 2010. For the decomposition analysis, non-need variables such as income, education, private insurance, and occupational status have contributed considerably to pro-rich inequality in health care over the period between 2005 and 2010. Conclusions: We found that health care utilization in Korea in 2010 was fairly equitable, but the poor still have some barriers to accessing primary care and continuing to receive medical care.

Objectives: The purpose of this study was to confirm the relationship between socioeconomic characteristics and the prevalence of periodontal disease, with a focus on employment status, in a representative sample of Korean adults aged 19-39 years. Methods: Data were obtained from 3,178 adults who completed the Korean National Health and Nutrition Examination Survey, health-related questionnaires, and an oral examination. Socioeconomic, demographic, and oral health-related behavior data were adopted as independent variables. The chi-square test was used to assess differences in the distribution of socioeconomic status, oral health behavior, and nutrition factors according to employment status. Logistic regression analysis was performed to confirm the relationships between the prevalence of periodontitis and the related variables. Results: Significant differences in sex, educational level, income, marital status, smoking status, prevalence of periodontitis, number of dental check-ups in a year, and unmet dental care were confirmed according to employment status. The prevalence of periodontal disease was not significantly related to employment status. Conclusions: These results suggest a significant difference in periodontal disease according to socioeconomic factors in Korean adults. However, the prevalence of periodontal disease was not related to employment status. To prevent the progression of periodontal disease, attention should be paid to oral health, time available for dental treatment, smoking cessation, and use of floss.
