Purpose: Measuring viability of a three-dimensional in vitro organotypic human oral tissue model has been suggested as an alternative test method to the oral mucosa irritation test of oral care products. The aim of this study was to investigate the production of two different cytokines using organotypic human oral tissue model following exposure to chemicals that are commonly used in oral care products. Materials and Methods: The organotypic human oral tissues were exposed to ethanol, sodium lauryl sulphate or hydrogen peroxide for 90 minutes. Following exposure, interleukin (IL)-1α and IL-8 productions were assessed and correlated with cell viability testing as well as histology of the organotypic human oral tissues. Result: High levels of IL-8 were released from organotypic human oral tissues in all of the test and control groups without any significant differences between them. In contrast, differences were found in IL-1α release between the test and control groups. Additionally, the trend of IL-1α release corresponded to the phenotypes observed in histological analysis while different trend existed between IL-1α release and cell viability. Conclusion: The study concluded the non-specific release of IL-8 for the assessment of oral care product chemicals' toxicity, while potential of measuring IL-1α cytokine level as the possible alternative test method.

Purpose: This study was conducted to explore the impact of nurse staffing level and oral care on pneumonia in elderly inpatients in long-term care hospitals (LTCHs). Methods: Data were obtained from the Health Insurance Review and Assessment Services (HIRA) including the profiles of LTCHs, monthly patient assessment reports and medical report survey data of pneumonia patients by HIRA in the fourth quarter of 2010. The sample consisted of 37 LTCHs and 6,593 patients. Results: Patient per nurse staff (OR=1.43, CI=1.22~1.68) and no oral care (OR=1.29, CI=1.01~1.64) were significantly related with hospital acquired pneumonia. The difference in percent of oral care by hospital was not significant between high and low group in nurse staffing level. Conclusion: In order to reduce the occurrence of pneumonia in eldery patients, effective nursing interventions are not only required but also nurse staffing levels that enable nurses to provide the intervention.

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.

In Korea, the elderly is defined as the person aged over 65 and the disabled is defined as the person who is registered with Ministry of Health and Welfare. In 2008, the elderly with disabilities was about 770,000. Korea was already poised for an aging society in 2000 and is ahead of and aged society in 2018 and a super aged society in 2026. So, the number of the elderly with disabilities will continue to grow. Various oral diseases can be seen in the elderly with disabilities due to the systemic disease and impaired self oral care, in addition to the physiological aging. Particularly, we should be care for the aspiration pneumonia, which is the major cause of the death of the elderly. As a professional for the special care dentistry, we should understand the general and dental, individual characteristics of the elderly with disabilities and do proper oral care and treatment. Thereby, the quality of life of the patients might be improved.

Background: Oral diseases are caused by various systemic and local factors, the most closely related being the biofilm. However, the challenges involved in removing an established biofilm necessitate professional care for its removal. This study aimed to evaluate and compare the effects of professional self and professional biofilm care in healthy patients to prevent the development of periodontal diseases. Methods: Thirty-seven patients who visited the dental clinic between September 2018 and February 2019 were included in this study. Self-biofilm care was performed by routine tooth brushing and professional biofilm care was provided using the toothpick method (TPM) or the oral prophylaxis (OP) method using a rubber cup. Subgingival bacterial motility and halitosis (levels of hydrogen sulfide, $H_2S$; methyl mercaptan, $CH_3SH$; and di-methyl sulfide, $(CH_3)_2S$) were measured before, immediately after, and 5 hours after the preventive treatment in the three groups. Repeated measures analysis of variance test was performed to determine significant differences among the groups. Results: TPM was effective immediately after the prevention treatment, whereas OP was more effective after 5 hours (proximal surfaces, F=16.353, p<0.001; smooth surfaces, F=66.575, p<0.001). The three components responsible for halitosis were effectively reduced by professional biofilm care immediately after the preventive treatment; however, self-biofilm care was more effective after 5 hours ($H_2S$, F=3.564, p=0.011; $CH_3SH$, F=6.657, p<0.001; $(CH_3)_2S$, F=21.135, p<0.001). Conclusion: To prevent oral diseases, it is critical to monitor the biofilm. The dental hygienist should check the oral hygiene status and the ability of the patient to administer oral care. Professional biofilm care should be provided by assessing and treating each surface of the tooth. We hope to strengthen our professional in biofilm care through continuous clinical research.

Purpose: The purpose of this study is to investigate effects of an oral self-care program on oral dryness and oral health related quality of life in the elderly. Methods: The current research design isa nonequivalent control group protest-posttest design with two groups of elders from two different senior centers in D city. Tools for the research include paper of salivary absorption (WF41-1850, Whatman, Germany), 6 items for subjective oral dryness and OHIP-14 for oral health related to quality of life. The data were analyzed to test three hypotheses by using the SPSS 22.0 program. Results: The three hypotheses were significantly accepted. The subjective oral dryness score was lower in the experimental group than in the control group (t=-2.45, p=.022). Salivary absorption was higher in the experimental group than in the control group (t=3.83, p<.001).Oral health related quality of life was better in the experimental group than in the control group (t=-2.11, p=.044). Conclusion: The oral self-care program has appeared to be effective on oral dryness and an oral health related quality of life in the elderly. Therefore, it can be suggested that the oral self-care program is applicable as an intervention program motivating the elderly to maintain oral health.

Objectives: The purpose of the study was to identify the oral care status and periodontal disease of middle aged daibetic patients in Korea. Methods: The primitive data were taken from 238 diabetic people in the 5th Korea National Health and Nutrition Examination Survey(KNHANES) in 2010 - 2012. The variables included general profiles(gender, age, occupied area, education, and smoking), oral care status(brushing time, brushing time, use of oral hygienic supplies, availability of oral hygienic supplies, oral examination, and recognition of oral health state), and diabetes management(morbidity period, treatment, education, and glycosylated hemoglobin levels). Results: Most of the subjects took gargling more than twice a day and it accounted for 73.5%. Oral hygienic supply users accounted for 24.8%, and most of them used floss brush. Oral examination was done in 19.3% of the respondents and 55.0% thought that their oral health status were very poor. The prevalence rate of the periodontal diseases was 46.6%. Female tended to have a higher rate of periodontal disease than the male. Oral hygienic supply users had lower rate of periodntal disease than those who did not use. Those who had poor subjective oral health status had higher prevalence rate of periodontal disease than those who did not. Conclusions: Periodontal disease is closely related to good oral care of middle aged diabetic patients. It is necessary to develop the program for the prevention of the periodontal disease for the diabetic patients.
