There are two purposes in this study. The first one is to collect some oral health information through the investigations upon the oral health care of Korean adults. Referring to the result of the investigation. I wanted to furnish fundamental data with oral health education for each age and with a publicity booklet editing. That is the second purpose of this research. Among the people who visited Seo-gu Public Health Center in Kwang-ju, 207 people answered the questionnaires. There were 86 men and 121 women from the 20-aged to the 59- aged. The questionnaires covers knowledge aquisition path for dental caries prevention, the cognition degrees for the causes of dental caries and its prevention, the cognition degrees for the causes of periodontal disease and its prevention, the degrees for oral health methods, and the importance of oral health. The conclusions are as follows; 1. The cognition degree for dental caries prevention: The cognition for pit and fissure sealant was appeared most highly in thirties by 85.3%. but 62.1 % in fifties was answered, "Never heard". The cognition degree for fluoride application was appeared most highly in thirties by 73.5%. and the cognition degree for water fluoridation was most highly in forties by 54.2%. 2. The knowledge for pit and fissure sealant was acquired mostly through dental hospital in every age by 54.2%. 3. The knowledge for fluoride application was learned mostly through dental hospitals in twenties and thirties by 32.7%. and mostly through TV or radio health programs in forties and fiftieseach by 35.7% and 50.0%. 4. The knowledge for water fluoridation was acquired through TV or radio programs in all ages such as twenties. thirties. forties and fifties. Its rate was 57.8%. 5.

Objectives: The aim of this study is to analyze the differences in factors related to the incidence of dental caries between children in fluoridated and non-fluoridated areas and compared the DMFT and DMFS scores to confirm the effect of water fluoridation program (WFP) in Geoje and Changwon. Methods: The oral health examination and questionnaire survey were conducted in fluoridated and non-fluoridated areas. The number of surveyed children aged 8, 10, and 12 years in the fluoridated and non-fluoridated area of two cities was 1,524 and 1,383, respectively. Self-recorded questionnaires included self-perception of their own dental health, daily toothbrushing frequency, intake frequency of cariogenic sweet snacks and beverages, experience of gingival bleeding, experience of unmet dental treatment, and use of oral hygiene device except for toothbrush and toothpaste. The prevalence of caries and fissure-sealant status were surveyed. The logistic regression analysis was used to analyze the difference in children's self-rated oral health status between the fluoridated and non-fluoridated area. The mean number of sealed teeth and surfaces, marginal means of the DMFT and DMFS scores adjusted for the difference in the samples' sex distribution, and region were compared between the fluoridated and non-fluoridated areas. Results: In the fluoridated area, the experience rate of unmet dental treatments was higher among children aged 10 years, intake frequency of cariogenic sweet snacks and beverages were higher among the whole sample, and experience rate of professional fluoride application were lower than in the non-fluoridated area. The DMFT score for permanent dentition adjusted for differences in sex, region, and mean number of fissure-sealed teeth in the fluoridated area was significantly lower among whole samples and 8-, 10-, and 12-year-olds alone than in the non-fluoridated area. Conclusions: WFP can alleviate oral health inequality because it is effective in reducing the incidence of caries among children is disadvantaged demographic, socioeconomic, and cultural contexts.

The fabrication of a controlled surface is of great interest because it can be applied to various engineering facilities due to the various properties of the surface, such as self-cleaning, anti-bio-fouling, anti-icing, anti-corrosion, and anti-sticking. Controlled surfaces with micro/nano structures were fabricated using an ion beam focused onto a polypropylene (PP) surface with a fluoridation process. We developed a facile method of fabricating hydrophobic surfaces through ion beam treatment with argon and oxygen ions. The fabrication of low surface energy materials can replace the current expensive and complex manufacturing process. The contact angles (CAs) of the sample surface were $106^{\circ}$ and $108^{\circ}$ degrees using argon and oxygen ions, respectively. X-ray photoelectron spectroscopy (XPS) and Fourier transform infrared (FT-IR) spectroscopy were used to determine the chemical composition of the surface. The morphology change of the surfaces was observed by scanning electron microscopy (SEM). The change of the surface morphology using the ion beam was shown to be very effective and provide enhanced optical properties. It is therefore expected that the prepared surface with wear and corrosion resistance might have a considerable potential in large scale industrial applications.

The purpose if this study was to investigate mother' oral health management behavior to their children. Two hundreds sixty seven mothers with elementary school students were surveyed among the residents living of Iksan city, Korea. A questionnaire was constructed and administered to the samples. The research focused in the following items: the subjects' socio-demographic factors such as education level and employment and so on; their knowledge of plaque; the leading causes of caries, regular dental examinations; dental treatment; their interest in their children's dental health; the frequency of the subjects examining their children's teeth; non-cariogenic food preparation, etc. Being based in collected data, mothers' oral health management behavior to their children were analyzed according to maternal socio-demographic factor and result were following. There was a difference in the subjects knowledge of dental plaque in accordance with their employment or unemployment and family income. There was no difference in mother's oral health management behavior to their children according to parents' education level, the subjects' age and family income. Most of mother answered the main reason of dental caries was that their children did not toothbrush their teeth regularly and there was a difference in the understanding of the subjects in accordance with the education level of fathers and family income. The subjects had a low understanding of the effect of preventing caries with the help of fluoride. They didn't have enough understanding of water fluoridation. So it is necessary that active campaigns should be launched to enlighten people in relation to the ways of preventing dental caries with fluoride.
