Objectives: The purpose of the study is to investigate the influencing factors of subjective awareness of dental health status on the use of dental hygienic devices. Methods: A self-reported questionnaire was completed by 320 patients who visited dental clinics in Seoul and Gyeonggi-do from May to June 2014. Except incomplete answers, 284 copies were analyzed by SPSS WIN 18.0 program. The questionnaire was adapted from Park & Youn, and Chae. The questionnaire consisted of five questions of the general characteristics of the subjects, one question of subjective dental health status, eight questions of awareness of dental hygienic devices, and eight questions of use of dental hygienic devices. Results: Although the awareness of self dental health state was shown to statistically significantly affect the awareness of dental hygiene devices(p<0.001) which is the dependent variable, it was shown to not affect the use. Conclusions: Based on such results, to improve and maintain the dental health, an individual's subjective dental health state should be identified and provide accurate and objective information on the dental hygiene devices that are suitable to individual dental state, as well as make the patient's use of dental hygiene devices increase through continuous boosting of motivation.

The purpose of this study was to investigate the perception of calculus removal, an essential factor in periodontal disease in the elderly population. Further, the study aimed to identify the oral hygiene management matters of individuals and to use the information as primary data for preventing dental loss and improving the prevention of chronic diseases. From December 20, 2019, to January 15, 2020, the results of 171 studies on oral hygiene management and awareness of calculus removal among the elderly aged 65 or older in Busan and Gyeongnam are as follows: The elderly with good health appreciated their functional oral health status and showed significant differences (Χ²=298.26, p<.001). Many of the elderly brushing their teeth at least three times a day had a better health status and showed significant differences according to their health status (= 134.42, p <.001). Usually, older people who are in good health have a dental floss (Χ²=89.31, p<.001), and the dental floss were used more often and significantly differed depending o health status (Χ²=92.53, p<.001). The elderly's perception of tartar removal has shown that the overall average out of five points is positive at 3.48. Older female adults were more positive and showed significant differences regarding gender (t=-7.95, p<.001). Senior citizens aged 65 to 70 were more positive about dental removal than those aged 71 or older, with significant differences in age (t=6.65, p<.001). As described above, oral hygiene management for the elderly population needs to develop a periodontal disease prevention program linked to systemic diseases, considering that there are many chronic diseases.

Background: Plastic waste generates pollutants in the process of incineration or landfilling, and accumulates in water or marine organisms, causing adverse effects on the environment and the human body. Recently, various eco-friendly oral hygiene products (Eco-OHPs) such as bamboo toothbrushes and biodegradable plastic toothbrushes have been developed. Therefore, this study aimed to investigate the current level of awareness and purchasing status of eco-OHPs among adults who are interested in eco-friendly products. Methods: This study included adults aged >19 years who regularly visited eco-friendly shops and online sites; the online survey links were distributed during their visits to eco-friendly Internet cafés and companies. Of the 22 questions, seven assessed the participants' general characteristics, three assessed the general oral hygiene care products used, six assessed the level of awareness of Eco-OHPs, and six assessed the purchasing status of Eco-OHPs. Frequency analysis, chi-square test, and regression analysis were performed using SPSS software. Results: Among the respondents, 108 (51.4%) were aware of Eco-OHPs, and 79 (37.6%) had experience purchasing Eco-OHPs. The most common reason for not purchasing was the lack of information about related brands or products (74, 56.5%). The most common platform used in obtaining information was the Internet (general: 31.5%, eco-friendly: 46.3%), such as Social Network Service, Internet cafes, and blogs. The experience in purchasing Eco-OHPs was affected by whether the respondents recognized the possibility of contributing to environmental preservation, availability of vendors, product safety, and the number of eco-friendly products purchased. Conclusion: In order to expand the use of Eco-OHPs, various efforts such as promotion of eco-friendly characteristics, determination of related vendors, reliable analysis of product safety, and expansion of product experience opportunities are required.

Objectives: This study aimed to validate the moderating effect of oral health on the relationship between perceived health status and health-related quality of life in the elderly and to use this information as primary data to suggest oral health policies for the aged society. Methods: This study included 3,707 subjects aged over 65 years who answered all the variables used in the study model and completed the health questionnaire and screening survey based on the sixth Korea National Health and Nutrition Examination Survey. Baron & Kenny's linear regression analysis using SPSS 22.0 and SPSS Macro Version 3.1 programs was performed to confirm the moderating effect of the number of remaining natural teeth, chewing difficulty, and cardiovascular disease on the relationship between perceived health status and healthrelated quality of life in the elderly. Results: The number of remaining natural teeth, chewing difficulties, and cardiovascular diseases affected the perceived health status of the elderly. As the number of remaining natural teeth increased, the effect of perceived health status on the quality of life in the elderly was buffered. The effect of perceived health status on the quality of life increased with chewing difficulties and the number of cardiovascular diseases. In particular, it was confirmed that chewing difficulties, rather than the number of cardiovascular diseases. had a greater effect on the quality of life in the elderly. Conclusions: Oral health policies and projects are required to ensure oral rehabilitation with dentures and implants and restore chewing function to improve the quality of life of the elderly in Korea.

Purpose : The easiest and most cost-effective way to prevent medical-related infections is known as proper hand washing of health care workers. The experience of MERS in domestic medical institutions has increased the importance of hand hygiene for medical workers to prevent infections in hospitals. It is necessary to investigate the level of hand hygiene practice by type of medical institutions and the factors influencing the infection prevention. Methods : Domestic and overseas hand hygiene related business cases and literature data were collected and analyzed in order to investigate the hand hygiene status of medical institutions in Korea. Result : As a result of hand hygiene monitoring of all hospital-level medical institutions in 2016, the total number of observations was 24,328 and the hand hygiene performance rate was 75.9%. The hand hygiene performance rate of hospitals was 71.5% for general hospitals, 75% for general hospitals, and 81.3% for hospitals. Implications : In general hospitals and hospitals, the HR(Hand Rubbing) method is preferred as a way of performing hand hygiene, whereas the HW(Hand Washing) method is relatively high in the small hospitals. It is estimated that the HW system is preferred because of the cost burden at the hospital medical institution. Therefore, it is necessary to compensate the related expenses to improve the hand hygiene performance of the physicians who are engaged in the hospitals.
