Objectives : The purpose of this study was identified about oral health status and oral health needs of elderly. Moreover this study would be based further research of development of oral health in elderly. Methods : This study was undertaken to determine the oral health status and the need of oral management of over 65years elderly who were with dental prosthesis in elderly welfare center and Kyung Ro Dong in Kyung Bok and Kyung Nam. The results were as follows. Results : The sample was 200 participants. The demographical characteristic were that 74.0% of participant was female, 29.0% of participant was 75~79 years old, 42.5% of participant was under elementary, and 45.5% of participant was living alone. 43.7% of participant was pain from muscle-skeletal disease, 37.1% of participant was cardiac-vascular disease, and 31.1% of participant was ophthalmic disease. In oral health status, 54.5% of participant was partly artificial tooth and 45% of participant was whole artificial tooth. 78.0% of participant used under 10 years with partly artificial tooth and only 27.4% were satisfaction with artificial tooth. 83.5% of participant used under 10 years with whole artificial tooth and only 26.4% were satisfaction with artificial tooth. In the oral health status of partly artificial tooth, the average of toothbrush was 2 times, 42.2%. The majority method of toothbrush was 'their own freely' 55.0%. The time of toothbrush was 'after meal' 81.8%. The study result showed that majority participant didn't experience of tongue brush, regular examination, scaling, and oral health education. In the need of oral management with the whole artificial tooth, the participant who used longer artificial tooth was significantly higher about artificial irrigation and the method of management(p<.05). The need of participant who answered 'don't gum massage', was higher of xerostomia treatment(p<.01) and halitosis treatment(p<.05). In the need of oral management with the partly artificial tooth, the participant who used longer artificial tooth was significantly higher about regular examination(p<.01), oral cavity massage(p<.05), scaling(p<.05), dental caries treatment(p<.01). The need of participant who answered 'don't satisfaction with artificial tooth' was higher of regular examination and scaling(p<.05). Conclusions : Oral management needs of elderly who kept artificial tooth or denture required were regular dental examination, xerostomia management, management of artificial tooth and irrigation, and management of bad breath.

Objectives : This study aimed to research subjective recognition of oral health, oral disease prevention, and knowledge of oral health among high school students to provide basic data necessary to develop an oral health education program for helping them prevent oral diseases and improve oral health in the future. Methods : Respondents' general characteristics and knowledge of oral health were estimated at frequency and percentage, and chi-square $(x^2)$ test was carried out to make a comparison for subjective recognition of oral health and oral disease prevention by general characteristics. ANOVA was used to get scores concerning knowledge of oral health care by general characteristics, and Pearson correlation was used to analyze correlation between recognition of oral health, oral disease prevention, and knowledge of oral health. Results : The findings of the study were as follows: 1. The percentage of those who had visited a dental clinic (hospital) within the previous one year (p<0.01) and had a regular oral examination (p<0.05) was higher in female students than in male ones, and percentage of those who had experienced oral health education (p<0.01) and who had regular oral examination (p<0.001) was highest in 11th graders. The percentage of those who used oral health products (p<0.01) and had pit and fissure sealing (p<0.01) was significantly higher among low-grade students, and the percentage of those who had scaling (p<0.01) was significantly higher among high-grade students. 2. Knowledge of oral health management was higher in female students (12.6) than in male ones (11.2) (p<0.001). Conclusions : A systematic oral health education program is necessary to help high school students improve recognition, prevention, and knowledge concerning oral health care, and continuous attention and efforts must be given to activate continuous oral health care implemented at the elementary level by inducing secondary school students to go on with it.

The purpose of this study was to identify effective ways to prevent periodontal disease in adults with risk factors for metabolic syndrome based on health examination examinees of some area. The study participants included 9,902 subjects who had received health checks at the Korea Association of Health Promotion from January 1 to December 31, 2014. All data were analyzed by descriptive statistics, chi-square test, logistic regression using IBM SPSS 24.0 Ver. As a result, it was found that regular oral examination (0.579), use of oral products (0.499), and oral health education (0.358) are most likely to affect the incidence of periodontal diseases among those affected by metabolic syndrome. The odds ratio of periodontal disease increased 1.79 times without regular oral examination, 1.61 times without oral products, and 1.43 times without oral health education (p<0.001). In conclusion, the results suggest that people with metabolic syndrome have a high risk of periodontal disease and that regular checkups, use of oral products, and oral health education are very important to prevent periodontal disease.

Objectives: The aim of this study was to investigate the effect of breastfeeding on the occurrence of early childhood caries in Korean infants and toddlers. Methods: Data on oral examinations of infants and toddlers of the National Health Insurance Service were analyzed. The study subjects were children who participated in both the first, second, and third oral examinations and the first general health examination in 2008-2017 (n=142,185). Based on the responses to the questionnaire, the subjects were classified into breastfeeding, formula feeding, and mixed feeding groups. The participants were monitored for the development of early childhood caries in three sequential oral examinations. Results: Based on the oral examination results conducted at 54-65 months old, the decayed-filled teeth index of the breastfeeding group was the highest (2.03±3.08), followed by the mixed (1.96±3.03) and the formula feeding groups (1.82±2.91). The Cox proportional hazard regression model including all the variables showed that the risk of developing dental caries was significantly lower in the formula (hazard ratio [HR], 0.85) and mixed feeding groups (HR, 0.91) than in the breastfeeding group. Conclusions: Breastfeeding children have a higher risk of early childhood caries; therefore, oral hygiene education and regular dental check-ups are necessary.
