This study was conducted for 3 months from April 2011 to June 2011. Excluding those obtained from 34 respondents who gave inadequate responses to given questions, the data from 312 respondents were analyzed. Results : 1. The number of senior citizens who chose 'Sometimes' to as an answer to the question about the self-perception of their own oral conditions such as mastication, swallowing, gingiva hemorrhage, dry mouth, and/or oral malodor was the largest. As an answer to the question about the presence of interpersonal avoidance, 'No' accounted for the largest proportion. The number of respondents choosing gingiva treatment regarding the perception of the necessity for medical interventions was the largest. 2. In regard to the knowledge of oral health care, the percentage of correct answers was the highest for 'I brush my tooth before each meal' ($0.69{\pm}0.156$), while the lowest percentage of correct answers was seen for 'Gingival diseases can be improved by medications' ($0.33{\pm}0.472$). Conclusions : Based upon the above mentioned results, the author conclude that developing relevant national programs and support policies at a national level as well as implementing proactive and systematic home-visiting oral health programs at the levels of local autonomous entities or communities will lead to significant improvements in senior citizens' oral health and QoL (quality of life).

Objectives : The purpose of this study was to investigate the relationship between the oral health status of elderly people and their oral health-related quality of life. Methods : The subjects were the elderly people over 65 years old in Busan. A total of 479 elderly people participated in the study from general hospital, two research institutes, eight dental clinics, six welfare institutions, sixteen senior centers, and three nursing homes. The oral health impact profile-14 (OHIP-14) was used in the routine dental checkups of the elderly people. Results : Those who had no oral symptoms had a better oral health-related quality of life. Among the subfactors of the OHIP-14, significant differences were shown in functional limitation(p=0.001), physical pain(p<0.001), emotional discomfort(p<0.001), physical disability(p=0.001), emotional disability (p=0.001), social disability(p=0.005), physical handicap(p=0.003) and total OHIP-14(p<0.001). Those who had 18 sound teeth(natural teeth) or more had a better oral health-related quality of life. Among the subfactors of the OHIP-14, significant differences were shown in functional limitation(p<0.001), physical pain(p=0.007), emotional discomfort(p=0.019), physical disability(p=0.018), Emotional disability(p=.032) and total OHIP-14 (p=0.006). Conclusions : The results revealed a close relationship between oral health status and oral health-related quality of life. The number of sound teeth(natural teeth) and frequency of toothbrushing had a more positive influence. Therefore oral health programs for the elderly people can preserve remaining teeth. Toothbrushing is the best way to improve the quality of life in the elderly people.

Objectives: The purpose of this study was to contribute to the development of an oral hygiene care program for patients with dementia by understanding the oral care status and oral health knowledge of care workers and caregivers with regard to patients with dementia. Methods: For about two months from May to June 2018, a survey of care workers and caregivers working in long-term nursing homes and elderly-specialized nursing hospitals was performed, and 442 people were selected for the final analysis. The frequency and percentage were calculated to understand the oral care status and oral health knowledge regarding patients with dementia, and an independent t-test was conducted to determine the difference between the elderly oral health knowledge of care workers and caregivers. Multiple regression analysis was also carried out to examine factors affecting elderly oral health knowledge. Results: With respect to the factor of oral health education in elderly oral health knowledge, oral health knowledge was shown to be highest when participants responded that education was unnecessary (p<0.001), and regarding the will to participate in oral health education, oral health knowledge was highest when participants responded as having no desire to participate (p<0.05). Conclusions: These results suggest that a standard manual should be developed for the accurate and qualitative management of oral hygiene care tasks performed by care workers and caregivers who are in charge of oral care for patients with dementia in order to provide continuous and systematic oral care.

This study aims to investigate the utilization status of dental services by foreign children living in Seoul and their level of satisfaction with the treatments. We developed a structured questionnaire with 35 questions, which comprised 14 questions (demographic characteristics) and 21 questions (oral hygiene and dental experience of the child). In this study, the distribution of nationality of 391 participants differed from the actual statistics in Korea. It consisted of high percentage of participants from African countries (23.6%), as well as North American countries (24.1%). In addition, the education status of most parents was above the level of college graduate. Despite the relatively high socioeconomic status of the participants, they showed minimal dental health knowledge regarding the aspect of oral hygiene. Utilization of dental health services and the types of dental clinics visited by them were similar before and after coming to Korea. The participants showed overall satisfaction with the care, but many of them expressed the need for improvement with regard to treatment fee and communication. In conclusion, foreign children living in Seoul require appropriate dental health education and governmental support to promote regular dental check-ups, to improve their overall oral health, and prevent the incidence of dental caries.

This study aims to analyze the major factors in their working conditions affecting the enlargement of leisure activities of dental technicians. We also present a need for dental technicians to assign more time many different kinds of leisure activities for their quality life. To this end, we examined the status and the characteristics of dental technicians' leisure activities among the randomly selected subjects who are working in the area of Seoul, Gyonggido, and Gangwon-do through the analysis of the 311 sheets of self-administered questionnaires. The conclusions from this analysis are as follows; 1. On weekdays, non participants in leisure activities were found to be 64.0%, and in the case of weekends, the participants were reached to 70.7%. Those who enjoy any leisure activities in either of weekdays and weekends were 34.1%, 27.3% of the dental technicians did not have any leisure activities. Therefore, statistical significance was shown in the participations of leisure activities between weekdays and weekends. 2. Of the types of leisure activities in both weekdays and weekends, sports activities were ranked at the top 33.4%, 29.6% respectively, which is followed by going to the cinema/theatre/exhibitions, etc 21.9%, 26.0%, games/entertainment 14.5%, 14.8%, hobbies/cultural activities 14.1%, 12.5%, sightseeing/picnic 6.4%, 7.4%. 3. Of the differences in the characteristics of leisure activities, the types of leisure activities between weekdays and weekends showed difference in gender, company and information regarding leisure activities in age, company and the place of leisure activities, and leisure information in the marital status, career and monthly income in company, company and leisure information in the job position, which is statistically significant (p<.001). However, no statistical significance was found among the other general items of the characteristics of leisure activities. Considering only works on weekdays policy is currently permeating into almost every business sector, dental business owners or managers are advised to consider more effective time management or human resources management, such as keeping reasonable manufacturing time through cooperations with the dentists, regularity of working hours, incentive system, introduction of credible over time payment. Which will provide their staff with more times and opportunities to enjoy their leisure activities. Additionally, the concrete and feasible ways of motivating and activating the leisure activities of dental technicians are in need of further researches and studies.

Methods : Complex sampling procedure was used to analyze the fourth data(2007-2009) of Korea National Health and Nutrition Examination Survey. When preparing planning file, the estimator of variance as a stratification variance (variance name : kstrata), population of survey unit as a cluster variance(variance name : PSU), and previous exam and nutritional related weighted as a weighted were analyzed by considering reproduced survey and nutritional related total weighted. Complex samples chi-square test was used to estimate the relation between number of natural teeth and inadequate intake and relation factors included in the model were analyzed by complex samples logistic regression analysis. Results : The group of edentulous had a higher risk to intake less nutrient, except calcium, riboflavin and vitamin C than recommended level comparing to reference group which had natural teeth more than 20(phosphate : OR=1.763; 95% CI=1.273-2.443, thiamine : OR=1.748; 95% CI=1.276-2.395, protein : OR=1.610; 95% CI=1.213-2.138). Conclusions : The number of teeth in Korean elderly over 65 years old had a relation with nutritional status in this investigation. Especially, intake level of nutrients was different between the edentulous group and the reference group. Therefore, dental health care is needed from young and middle age to keep health dental condition for through whole life as well as old age. Although the dental condition of the aged is not good, it is evitable to educate them about the relation between dental health and nutritional ingestion to take balanced nutrition, we think.

There is a need to comprehend dental accidents accurately, and construct patient-safety-system in order to prevent consistently increasing dental accident or dispute. This study is aimed to provide basic data for an efficient counterplain by looking through and classifying already occurred dental accidents from an angle of patient safety. Recently, the number of dispute on dental implant was the highest according to rapid growth of dental implant. As a result of classifying dental accidents by International Classification for Patient Safety (ICPS), it is confirmed that cause of accident is different by each type of dental treatment. It is expected to help preventing and managing dental disputes properly by studying actual state of dental disputes in perspective of patient safety. Effort to reduce dental accidents and activity to pursue patient safety have thread in connection. I believe that financial profits of dental clinic and improvement of quality in dental treatment can be achieved through these efforts.
