Background: Edentulism is associated with socioeconomic status, rural residence, and chronic disease, but no studies have investigated edentulism and residence factors together. All information that drives a better understanding of the factors related to edentulism plays an important role in the planning and delivery of appropriate dental services for the elderly by national and oral health professionals. This study was designed to investigate the prevalence of edentulism in adults aged over 60 years in Korea and to examine whether there are differences in dentate status between people living in urban and rural areas after controlling for sociodemographic and other related factors. Methods: The data for this study were collected from 2013 to 2015 as part of the Korea National Health and Nutrition Examination Survey VI, those individuals aged over 60 years and who had complete datasets were included (5,071). The number of teeth and residence status were categorized into two groups: edentate and dentate (1 or more); urban and rural. Multiple multivariate logistic regression analyses were sequentially applied to assess the association between dentate status and residence status after adjusting for potential confounders. Results: Rural areas, lower household income, and lower education levels were associated with a higher edentate rate. The number of teeth was lower in rural areas than in urban areas. After adjusting for various factors, statistically significant associations were present for women, low household income, low education level, poor perceived health status, and alcohol consumption in participants. Conclusion: Elders living in rural areas had poorer oral health than elders living in urban areas. The government will need to provide effective systems for promoting oral health for elders living in rural areas.

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 aim of this study was to examine socioeconomic inequalities in oral health and to investigate the extent to which socioeconomic disparities in oral health are attenuated by oral health related consciousness and behaviors. Methods: We used data from the third 2006 Korea National Oral Health Survey(KNOHS) and a total of 3,457 subjects aged over 18 years were analyzed. The dependent variable was periodontal conditions which is devided into dichotomy, that is, health and ill-health, using the Community Periodontal Index(CPI) in KNOHS. Socioeconomic status(SES) were measured by educational attainment, income and residential area. Age, gender, oral health consciousness(self-assessed oral health status, concern about oral health and self-perceived dental treatment needs and behaviors(brushing, use of dental floss and dental visits) were adjusted in binary logistic regression analysis. Results and Conclusion: The results show that oral health consciousness and behaviors do not mediate the relationship between SES and periodontal health and there might be limitations to attenuate socioeconomic disparities in oral health only by changing of either oral health consciousness or(and) behaviors. Our findings suggest that more definite oral health policies and dental health education among adults with lower education will need in order to improve oral health.

Objectives : The objective of this research was to investigate the smoking state of students in Y university, located in Youngdong-gun, Choungbuk. Methods : This research was conducted toward 311 number of students in the university. The questionnaire basically consists of the status of smoking, the behavior of smoker and non-smoker. Results : 58.2% of the male respondents were current smoker, but 72.4% of the females were non-smoker. 58.2% of the current smokers were 22 to 25 aged group. The highest rate of time to begin with smoking was in 15 to 18 years old and the most of people consumed 11 to 20 pieces of cigarettes per day. 48.9% of the students have an experience to keep no smoking more than one month. There were reverse correlation(r=-.335) between the status of smoking and sex, and positive correlation(r=.264) between the status of smoking and an age. Of the people experiencing non-smoking, 55.3% were smoking 'everyday' and 44.7% were 'sometimes'. The biggest part of the reason why stopped smoking was for 'the advices of other people'(25.5%), and 'Harm to health' and 'Social atmosphere of non-smoking'(21.3%) were following. Conclusions : In the university students, current smokers among male students were still high smoking rate. Therefore Dental Hygiene students in the same University have to provide the quit smoking education and oral health care methods for current smokers.

Objectives: The aim of this study was to confirm health behaviors that affect periodontal health status. Based on these results, we also intended to provide information for the prevention of gingivitis prior to periodontitis and establish strategies for maintaining healthy periodontal tissues. Methods: Data for this descriptive study were extracted from the Korea National Health and Nutrition Examination Survey 2013-2015. A total of 2,710 adults, aged 19-39 years were included in this study. Complex logistic regression analyses were performed to confirm relationships between health behaviors and periodontal health, after adjusting for socio-demographics, oral and systemic health status. Results: Dental clinic visits (odd ratio [OR] = 1.761, 95% confidence interval [CI]; 1.391-2.229), use of floss (OR = 1.504, 95% CI; 1.213-1.865), and non-smoking (OR = 1.269, 95% CI; 1.040-1.549) were found to support periodontal health. Conclusions: Dental visits for continued professional oral health care, self-oral care including interdental flossing, and a non-smoking habit, are necessary for periodontal health maintenance. Additionally, the results suggest that physical activities such as regular walking can help. These methods should be considered as the primary preventative care strategies for minimizing the occurrence of gingival inflammation.

Background: With increased interest in oral health, several efforts have been made to improve oral health conditions. To achieve this, needs for oral health must be precisely determined and accurately measured. Therefore, factors influencing both objective unmet dental needs, which were determined by experts, and perceived unmet dental needs, which were determined by patients, were examined in this study. Methods: Responses of 17,735 respondents aged greater than 19 years from the Korean National Health and Nutrition Survey collected using the fifth (2010~2012) rotation sample survey were analyzed. Based on the information collected from the survey and dental examination, we determined the associations between the independent (sex and socioeconomic level) and dependent variables using a chi-squared test. Moreover, ordinal logistic regression analyses on multiple categorical values were performed using perceived and objective dental needs as the dependent variables. Results: Generally, factors influencing both perceived and objective dental needs were similar. These included sex, household income, educational level, private insurance, and subjective oral health status. However, the high-income groups had lesser perceived and objective dental needs compared to the low-income groups. Furthermore, factors such as sex, educational level, and marital status had different influence on both needs. Conclusion: Generally, factors that affect perceived and objective dental needs were similar. To minimize unmet dental needs, factors influencing both perceived and objective dental needs should be examined for a broad dental insurance coverage, and efforts to prevent oral diseases are also required.

Purpose: The institutionalized elderly have placed the most vulnerable state, and the report about the oral health status of the institutionalized elderly was scarce. The aims of the current study were to investigate the oral health status of institutionalized elderly. Materials and methods: The survey of the oral health status was carried out on 487 institutionalized elderly from 4 longterm care facilities of Seoul metropolitan city, Gyunggi province, and Gangwon province in Korea. Results: The prevalence of dental caries, root caries, and dental calculus of the institutionalized elderly was 19.2%, 15.3%, and 23.7%, respectively. The percentage of edentulism among the institutionalized elderly was 26.2%. Those who had poor oral hygiene and tongue coating were 43.9% and 90.5%, respectively. The percentages wearing complete and removable partial denture on maxilla were 12.8% and 3.3%, respectively. The percentages wearing complete and removable partial denture on mandible were 7.8% and 5.6%, respectively. The percentages of institutionalized elderly needing complete and removable partial denture on maxilla were 29.7% and 27.2%, respectively. The percentages of institutionalized elderly needing complete and removable partial denture on mandible were 24.5% and 30.9%, respectively. Conclusion: The oral health stuatus of institutionalized elderly was poor. For the oral health promotion of elderly in longterm care facilities, it is essential to educate nurses and caregivers about the importance of the oral health and oral hygiene method.

Objectives: The purpose of this study was to examine the practice of oral hygiene behaviors and oral health status of long-term care facility residents and to analyze the factors related to salivary hemoglobin level which can predict active periodontal disease. Methods: From 30th October 2015 to 7th January 2016, a questionnaire was provided to 63 participants and their dental plaque and saliva samples were collected to assess the levels of salivary hemoglobin and dental plaque acidogenicity. In order to analyze the factors related to salivary hemoglobin level, multiple linear regression analysis was performed. Results: Toothbrushing was most frequently performed by the participants themselves (98.4%) and toothbrushing was performed after eating breakfast (81.3%). 68.8% of participants reported brushing their tongue. 35.9% of participants perceived having bad teeth, and 87.5% had high dental caries activity. The percentages of participants with hyposalivation and ${\geq}0.20{\mu}g/ml$ salivary hemoglobin level were 45.3% and 59.4%, respectively. The salivary hemoglobin level was significantly higher in the group in which stimulated salivary flow rate was ${\leq}0.70ml/min$, dental plaque acidogenicity was superior, and perceived having bad teeth (p<0.05). There was also a tendency for the salivary hemoglobin level to increase with age (p<0.05). Conclusions: Oral health status of the long-term care facility residents was still not improved, and the characteristics of salivary volume and dental plaque were important factors affecting salivary hemoglobin level. Therefore, it is necessary to operate an oral hygiene intervention program by oral health professionals in such facilities in order to provide residents with effective oral care aligned with their respective needs. Furthermore, it is necessary for caregivers to complete mandatory oral health education to improve the oral hygiene status of the long-term care facility residents.
