Objectives: This study was aimed at evaluating the effects of changes in the oral environment of the elderly in long-term care facilities after the intake of Weissella cibaria. Methods: The test group ingested the W. cibaria strain Chonnam Medical University (CMU), and the control group ingested the control food. Of all randomized trial subjects, 62 were analyzed (32 in the experimental group and 30 in the control group). In this 8-week demographic study, we evaluated self-perceived halitosis, changes in halitosis, sensory test results, tongue plaque index scores, saliva buffering capacity, and the salivary flow rate. Results: The W. cibaria CMU intake in the elderly in long-term care facilities during the experimental period did not demonstrate statistically significant changes in the salivary flow rate. However, self-perceived halitosis, organoleptic test results, tongue plaque index scores, and salivary buffering capacity demonstrated statistically significant differences between the experimental and control groups. These findings partially confirmed the beneficial effects of the W. cibaria CMU on the oral environment in the elderly. Conclusions: Research results on the role of probiotics in the oral cavity should be summarized, and utilization plans should be sought to obtain a clearer understanding of the clinical efficacy and related factors. The value of probiotic use may be high in improving the oral health of people by enabling treatment and prevention.

Background: Prisoners represent a population group that is disadvantaged, socially deprived and underprivileged, needing particular attention with regard to provision of necessary oral health care, health promotion and motivation and tobacco cessation. Considering the situation in prisons, smoking and tobacco chewing are burning issues related to health deterioration and economic loss that seem to be overlooked by the public health sectors. Aim: To assess prisoners' perception of tobacco use and cessation in Chhatisgarh, India. Materials and Methods: A pre-tested, close ended questionnaire was administered in the form of extensive face to face interviews, to assess perceptions regarding tobacco use and cessation in the central jail of Durg District of Chhattisgarh state, India. Results: Prevalence of tobacco usage amongst the prisoners was found to be 61%. Some 27% reported smoking, 44% used tobacco in the chewable form and 29% indulged in consuming tobacco in both forms i.e. smoked as well as chewed. Results suggest several recommendations for policy relevance such as provision of a prison dentist, a tobacco cessation counseling program and targeted eradication of oral cancer by educating the prisoners. Conclusions: Health is a fundamental human "right of everyone to the enjoyment of the highest attainable standard of physical and mental well-being". This applies to prisoners just as it does to every other human being. The alarming findings in the study suggest the need for dental treatment facilities and tobacco cessation counseling in prisons.

Objectives: This study aimed to examine the effect of the Oral Health Education Program (OHEP) on the change in the children's brushing behavior and reduction in the dental plaque index (PI) and to identify changes in their parents' perception of oral health. Methods: The OHEP was applied 44 children recruited from two childcare centers. We conducted a self-reported survey of the parents at baseline and evaluated the oral conditions of the children at baseline and after 5 weeks. Their brushing behavior was assessed once a week during the OHEP intervention period and daily at home thereafter. We measured the PI after a 12-week follow-up and performed repeated measures analysis of varience. Results: The average PI score of children significantly decreased at week 5 as compared to the baseline (1.90±0.53, p<0.001), despite a substantial increase in week 12 (2.67±0.08, p<0.001). OHEP was effective in reducing the PI score and modifying their brushing behavior. Conclusions: OHEP effectively modified the brushing the behavior of the children. Therefore, it is necessary to develop and expand a systematic oral health education program to promote self-management of oral health in children.

Purpose: This study conducted a survey on the elderly with physical debilities, who are in a medically vulnerable social class, to examine closely their demo-sociological characteristics, unmet needs, dental states, and living qualities and satisfaction levels relating to oral health and social supports to them, and also to prepare the basis for effective public medical policies and health improvement programs aimed at improving the quality of life for the elderly with physical debilities. Methods: Twenty-two elderly care facilities within Jeju Special Self-Government Province participated in the survey. Between 11 January and 5 March 2010, a total of 250 elderly persons(65 and over) with physical debilities were interviewed and their dental health was checked. Results: The results of the survey are as follows. The need for social support for dental care of the elderly with physical debilities was high in the medical institution-supported service (49.6%). The unmet needs for physical care were high in bathing (49.6%) and using public transportation (71.6%). More than half of these surveyed had ten or fewer teeth. The survey found that 31.6% of the participants experienced problems eating, due to poor dental health. Concerning quality of life, 30.5% of those surveyed experienced physical pain. Conclusion: In summary, the ages of the survey participants directly relates to the degree of behavioral debility experienced. The more debility a participant exhibits, the greater is the need for social support and dental care. The dental health of a participant directly relates to a higher quality of life. Good dental health of a participant translate to better quality of life. In light of the fact that the elderly with physical debilities suffer from a lack of accessibility to medical care and worse oral health than do other elderly persons, it is essential to increase accessibility to medical institutions that can provide such services as door to door dental care. Current insurance policies, funding for denture insurance, and free denture and denture-upgrade programs desperately need to be expanded. Therefore, to improve effectively the quality of life for the elderly with physical debilities civil dental medical resources should be encouraged to provide inclusive and prevention-focused medical care. In the public domain, door to door dental care services and cooperation with civil dental care resources need to be improved to increase impartial accessibility to dental medical institutions.

Background: The purpose of this study was to investigate longitudinal changes of the utilization of operational and surgical medical care inside and outside a metropolitan area over 10 years, analyzing the residential areas of patients and the locations of medical facilities for major cardiovascular surgery. Methods: Data analysis was conducted by classifying the addresses of patients and the locations of medical care facilities of metropolitan cities and provinces, using data from the National Health Insurance Corporation from January 2003 to December 2013. Results: There is serious concentration of major heart surgery to medical facilities in Seoul; this problem has not improved over time. There were differences in percentages of surgical procedures performed in the metropolitan areas according to major diseases. In the case of Busan and Daegu provinces, at least 50% of the patients underwent surgery in medical facilities in the city, but there are other regions where the percentage is less than 50%. In the case of provinces, the percentage of surgical procedures performed in medical facilities in Seoul or nearby metropolitan cities is very high. Conclusion: Policies to strengthen the regional capabilities of heart surgery and to secure human resources are required to mitigate the concentration of patients in the capital area. Many regional multi-centers must be designated to minimize unnecessary competition among regional university hospitals and activate a win-win partnership model for medical services.

Objectives: Based on the amount of amalgam, the duration of exposure, and the water pH, this study aims to investigate the change patterns in the mercury concentrations in water after amalgams have been introduced into sewage water. It is expected that the study results will be useful in improving the system for regulating the amount of mercury that is introduced into the environment. Methods: During the study, a glass test-tube with a cap was washed and disinfected using the glass laboratory device washing method. Then, 1, 2, 3, and 4 tabs were placed into a 10 mL pH 4 solution and 10 mL pH 7 distilled water. Each specimen was prepared in duplicate. The mean of the two mercury concentrations was used as the representative value, and the mercury concentration was measured using a mercury measurement device (DMA-80, Milestone, Italy) a total of eight times at one-week intervals. Results: The results show that the lower was the pH, the higher was the amount of amalgam. Also the longer was the duration, the more significant was the increase of mercury concentration in the water. Conclusions: Dental clinics are collected separately from dental clinics that used them. Given this, dental clinics in Korea must have the necessary facilities to separately collect mercury at their level. In addition, proper disposal systems and social attention to the proper management of dental wastes are required to prevent environmental pollution from mercury.

Objectives: The purpose of this study was to investigate the present conditions and problems of oral health care in senior citizens with dementia using a qualitative research method, through focused group interviews. Methods: Data was collected for approximately one month from May 2019. The subjects were divided into two groups: care workers and family caregivers. Fifteen participants were included in the study. Results: In-depth interviews with the care workers revealed the following three categories: characteristics of senile dementia patients, oral health care in senile dementia patients, and oral health care education. In-depth interviews with the family caregivers revealed the following four categories: characteristics of senile dementia patients, oral health care in senile dementia patients, oral health care education, and burden of care. The central themes common to both the care workers and family caregivers were the challenges owing to the characteristics of senile dementia patients, poor health condition of the senile dementia patients, difficulty in oral health care of the senile dementia patients, the desire to receive oral health care education and related information, and to access the information more easily. Additional central themes specific to the care workers were, the applicability of the intervention programs, variability between the facilities, and the problems of oral health care education. An additional central theme specific to the family caregivers was the burden of care. Conclusions: It is necessary to provide oral health care education and information to care workers and family caregivers of senile dementia patients, and to manage and support the dental health professionals ready to care for senile dementia patients. In addition, support to the family caregivers should not be limited only to the financial aspects, but also consider the psychological and emotional difficulties.
