The study aims to determine the status of oral health of mental illness patients and establish the preliminary data. The examinations and questionnaire survey were done 92 psychiatric patients to measure sociodemographic characteristics, decayed, missing and filled teeth (DMFT) index, patient hygiene performance (PHP) index, community periodontal index of treatment need (CPITN). Result of the missing teeth index in the state of oral health was higher in the hospital group (6.42) while the filled teeth index was higher in the center group (4.78). In the DMFT index, mental illness patients were higher than the national sample. The oral health status of medical aid recipients was poorer as the subjects were older and less educated (p<0.05). The PHP index was 3.41, close to the bad oral hygiene state. The hospital group (81.7%) required higher need for periodontal treatment. The periodontal health state was much poorer especially when the subject was in the age of 40's and 60's, received less education, and had no family (p<0.05). $CPITN_3$ was higher in the hospital group (13.3%) than the national sample (5.7%). The mental illness patients were socially vulnerable, therefore oral health care program should be needed and age, education level, health insurance type, presence of family and other factors needs to be considered in this approach.

Objectives: The purpose of this study was to apply an effective oral health promotion program and effect for underprivileged lower grade students. This study attempted to resolve some oral health inequality issues by providing underprivileged children with an oral health action program designed to promote positive oral health maintenance habits. Methods: This study was carried from May to August of 2009 with 77(control group 27 subjects, experimental group 36 subjects) elementary school students selected among first to third graders attending regional welfare center's after school program in Seoul. To the control group, conventional education methods were applied. To the experimental group, newly designed program was conducted by three project experts(1 expert, 1 dentist, 1 dental hygienist). It consisted of 5 sessions and progressed with various activities. It was focused on achieving target knowledge and changing oral health behavior. In order to evaluate the designed educational program, learners' achievement was evaluated with implementing the questionnaire and one-on-one interviews. And also the oral health improvement was evaluated based on change of Patient Hygiene Performance(PHP) index. Results: Based on the results of learners' achievement, the experimental group showed the significant increment of the oral health knowledge by the relapsed time, and it maintained after finished the program(p<0.001). The patient hygiene performance index showed not significant changed(p>0.05), but 1 month later the control group showed an increment of the PHP score, but the experimental group showed a decrement of it. Conclusions: Oral health promotion program by project approach could give a long-lasting educational effect to the children and encouraged proper oral hygiene behavioral changes.

The purpose of the study is to confirm the effect of the oral health management program in exemplary kindergartens for prevent the dental caries. The study performs the survey on the parents about the changes in the oral health behaviors after the oral health education in April 2012 and measures the patient hygiene performance (PHP) index before the education, after the education and 3 weeks after the education to assess the removal capability to plaque on the teeth surface for the children. The analysis is performed on 130 people who join the program and respond the survey. There is no change in the behavior related to the tooth brushing of children after the oral health education. No change is found from the interest in the oral health education (p>0.05) but the recognition in the importance of the tooth positively change, as well as recognition of the tooth brushing method and the reaction to recommending to tooth brushing. The PHP index of children is significantly improved from 3.87 before the education through 2.71 after the education and 3.27 3 weeks after the education (p<0.001). The observation from the patents shows that their children have interest in preventing the cavities including 33.1% after having xylitol and 60.7% after the oral health education. In conclusion, the study confirms the effect of the oral health management program in exemplary kindergartens to prevent the cavities, meaning that it is required to activate the programs and keep implementing the programs including providing xylitol and education for teachers, parents and children to habituate the oral health behavior of the children and completely learn toothbrushing method under continuous management and reeducation.

This study was executed to find out the outcome of Incremental Dental Care from September to November, 2004. 40 visitors to oral health center were examined on the oral conditions every week, seven times during above-mentioned period. Various tests were practiced in order to check their oral conditions before and after IDC such as tooth-brushing method/frequency/duration, calculus index, PHP index, halitosis and dental caries activity. Question and answer sheets were presented to student dental hygienists and 40 visitors respectively after IDC program. Results obtained are as follows. 1. Rotation method of toothbrushing increased from 27.8% to 88.9%. for men and increased from 27.3% to 95% for women. 2. Toothbrushing frequency increased from 2.8 times to 3.0 times a day for men and increased from 2.6 times to 3.1 times for women. Toothbrushing duration increased from 2.3 minutes to 2.8 minutes for men and increased from 2.1 minutes to 2.9 minutes for women. 3. Calculus index reduced from 0.5 to 0.1 for men and reduced from 0.7 to 0 for women. PHP index reduced from 3.7 to 3.0 for men and reduced 3.2 to 1.7 for women. However, halitosis didn't mark any significant difference before and after IDC. 4. Saliva buffering capacity of medium plus showed no change for men(94.5%), however increased from 95.4% to 100% for women. Dental caries activity of medium plus in S.mutans reduced by 4.3 times(72.2% to 16.7%) for men and reduced by 2 times(36.4% to 18.1%) for women. LB test results reduced by 1.5 times(50% to 33.3%) for men and reduced by 2.5 times(50% to 18.1%) for women. Alban's test results reduced by 1.4 times(83.3% to 61.1%) for men and reduced by 1.2 times(81.8% to 68.2%) for women. 5. All participants including visitors and students realized the importance of IDC and expressed a great satisfaction with IDC program.

This research was conducted by targeting pregnant women in the trial operation of dental hygiene care program with the focus on non-surgical periodontal treatments at the Maternal and Child Health center in the public health center. This study was conducted to provide basic data to dental hygienists who operate oral health promotion programs by targeting pregnant women of the local community through the evaluation on structure, the assessment process and results from the pilot program at the public health center. The targets are nine pregnant women who have been involved in the Dental hygiene care program three times. An evaluation on the structure, process and results according to the Indicators of each program were conducted. The results of dental hygiene care program found that the retention rate decreased. The retention of the probing pocket depth larger than 4mm was 40.4% to 14.0%(p<0.05). The retention rate of the gingival bleeding teeth was 4.6% to 2.7% (p=0.180). PHP Index improved. 1.7 points in the 1st to 1.4 points in the 3rd in the case of the second pregnant woman and 2.4 points in the 1st to 1.3 points (p<0.05) in the 3rd in the case of the third pregnant woman. The applicable and expandable possibility of the dental hygiene care program with the focus on non-surgical periodontal treatments at the Community Health Center is significant in the result of this study. In the future, long-term operation and ongoing monitoring of this program is needed.

Flora investigations in Korea have been conducted by many researchers for diverse purposes. Accumulated flora investigation data has not been utilized efficiently because there is no accessible database for comparison. To overcome this shortcoming, we constructed web-based database of flora investigation, named as the Integrated Korean Flora Database (IKFD; http://www.floradb.net/intro.php). Until now, 284 flora references (263 papers, 14 reports and books, and 7 unpublished papers written in between 1962 and 2017) were digitalized into the database. From 134,711 records, 4,301 species belonging to 228 families and 1,079 genera were identified via mapping with two major Korean plant species lists. Polygon areas originated from references were used for distribution of plant species, identifying precise distribution area. It will be a better index to show plant ecological characteristics. Collected micro-climate data provided by Korea Meteorology Administration were also integrated in IFKD for understanding correlation between distribution of plants and micro-climate. Cold hardiness zone which has been utilized for classifying climate zones. 12 out of 26 zones identified based on micro-climate data in Korea were mapped with distribution of plants. More than half species were appeared in zone 6a, 6b, 7a, and 7b. Taken together with these results, IKFD will be a fundamental platform for understanding plants in Korea flora investigation as well as a new standard for classifying distribution of plants. Moreover, Biodiversity Observation Database (BODB; http://www.biodiversitydb.info/intro.php) which integrates plant distribution data was also integrated for further studies.

This study conducted a 'specialist tooth brushing' method against the severely disabled once every other week. The purpose of this study is to analyze and validate the effectiveness of maintaining healthy periodontal management when consistent oral hygiene lasts with minimum stimuli for 24 - months. The conclusions were as follows. Table 2 compares the difference between group 1 and 2 from the 1^st to 11th management and verifies the actual difference in measurement of each index. Group 1 used a professional tooth brush while Group 2 used a general brush. There were found many significant differences in dental index. As for PHP, Oral Malodor index and gingival bleeding, it was found that one or two times of dental care can make substantial differences in dental health condition. These results show that as the number of toothbrush method has been increased, gingival bleeding and periodontal index are significantly improved, not to mention the improvement of gingivitis and periodontal disease. This is because periodontal tissue is affected by brushing method, brushing time and consistency of dental care. During the 6-month period, 20 minutes of active periodontal care was intensively conducted, and for 18-months the effect of consistent care was verified by 10-minute periodontal care once every other week. As a result of the test, it was found that there was no complete regression in the basic periodontal treatment and the periodontal health condition had been maintained for 24 months. Also this test shows that, despite of inconsistent dental hygienic care, regular plague control can prevent dental diseases and maintain the dental health. This study proved that periodontal condition can be maintained by periodontal care once every other week as the tooth brushing properly stimulates the gums with positive effect. Therefore, professional dental healthcareworkers should be designated for each facility for the disabled, and dental health of the disabled should be professionally cared on a regular basis, and consistent and repetitive management by the dental care specialist are required.

This study aims to analyze the effects of tooth-brushing facilities (TBF) at middle schools that installed TBF in 2012 as part of the oral health project in Seongdong-gu, Seoul. The subjects were the first graders at A middle school that installed TBF previously and B middle school that installed TBF in 2012. The results are as follows: DMFT, DMFS and CPI didn't show significant difference by schools (p>0.05), but code (0) was higher and code (2) was lower in female students than male students (p<0.05). As to PHP index, the students at A school with TBF indicated better oral hygiene (p<0.01). In the research on before and after installing TBF, the oral hygiene was improved significantly more after the installation than before (p <0.01). In the comparison on the oral health-related behavior, the percentage of not brushing after lunch was higher B school than A school and the frequency of toothbrushing after lunch was higher A school than B school (p<0.01). About the reasons why not to brush after lunch, there was difference in 'lack of the place' as A school showed 2.6% while B school without TBF indicated 14.2% (p<0.01). About the changes of the oral health-related behavior before and after TBF installation, the percentage of not brushing after lunch increased from 78.7% to 83.8% after the installation. The average frequency of tooth-brushing after lunch for one week also decreased from 0.50 to 0.34 (p>0.05). Among the reasons why not to brush after lunch, 'lack of the place' significantly reduced, but 'because other friends don't do it' increased greatly after the installation (p <0.05). Only with the improvement of oral health knowledge, we cannot expect either clinical or behavioral significance. Not only schools but policies of governmental agencies and financial support, cooperation of community-related groups for program development and evaluation will contribute altogether to helping teenagers to habitualize proper oral health management.
