A comparative study on the effects of the water fluoridation program and fluoride mouth rinsing program in the elementary school children. This study was performed to compare the oral health status of permanent teeth for children of the caries prevention effects by using methods of fluoride 309 children for water fluoridated program, 240 for fluoride mouth rinsing program and 248 for control group. The DMFS rate, DMFT index, soft and hard deposite rate were analysed from the oral examination. And 300 questionares from the parents who lived in Cheong ju city were evaluated to see the situations of using the tap water. The results were as follows; 1. Caries experience rate in permanent dentition was the lowest in fluoride mouth rinsing group. 2. It was estimated that soft deposite rate was comparatively low in the fluoride mouth rinsing group but calculus deposite rate was no significant difference in each other groups. 3. The 72.0 percentage of parents who lived in non fluoridated water area were misunderstood that they lived in water fluoridated area. 4. The 66.8 percentage of residents used the piped water as drinking water. 5. It was recommended that fluoride mouth rinsing program was suggested in rural area, on the other hands, toothbrusing program in urban area with water fluoridation to prevent the dental caries for school children.

Objectives : The purpose of this study was to survey some soldiers oral care products along recognition, and thereby to identify possible correlations among those factors. Methods : Questionnaire survey was carried out targeting 272 soldiers. The collected data was performed frequency & percentage, fisher's exact test, chi-square test and multiple regression analysis. Results : Respondents approving the implementation of water fluoridation were 50.5%. The general factors of approval were age, education, Monthly household income. The knowledge factors of approval were experience of hearing of this program, the knowledge of the purpose of this program, the knowledge of the some regions in South Korea had been implement water fluoridation. The results of multiple logistic regression analysis were the awareness of oral health and the knowledge level of water fluoridation were related with this program approval. Conclusions : The study suggest that oral care products should be include in military dental health care program. In addition to development dental health programs each military unit is dental health care between Korean soldiers.

Adjusted water fluoridation has been disputed because of its various effects on human health. Previous studies have been concerned with the difference in bone mineral density (BMD) between water fluoridated (WF) and none water fluoridated (NWF) districts. The aim of this study is to examine whether water fluoridation affects BMD. BMD was measured by dual energy X-ray absorptiometry (DXA). 386 adults(174 males and 212 females) in Ansan (WF) district and 399 adults (176 males and 223 females) in Sihwa (NWF) district, participated in this study. The Ansan and Sihwa districts are similar in residential environment and living class. The relationship between serum fluoride concentration and BMD was also examined by analysis of the serum fluoride concentrations from 402 inhabitants of the Ansan district. In females, the BMD of subjects living in Ansan ($0.457{\pm}0.008$) was a little higher than that of Sihwa subjects ($0.446{\pm}0.008$), although it is not significant, after adjusting for BMI, physical activity level, educational achievement, smoking volume, menopause status, and number of births. However, the BMD of Ansan subjects ($0.532{\pm}0.020$) in their forties was statistically higher than that of Sihwa (0.498{\pm}0.019). No relationship was found in males. In residential periods, there was significant difference (Ansan $0.467{\pm}0.013$, Sihwa $0.434{\pm}0.012$, p=0.0125) in the BMD between females of two districts, particularly in the group of over 6 year long-term inhabitants. On the contrary, there was no remarkable difference in males from the two districts. Serum fluoride concentrations in females were associated with BMD, especially in the age group of forties (p=0.0457). No relationship was observed in the male group. Analysis of adult BMD over the age of 20 in a water fluoridated and a none water fluoridated district, confirms more or less a higher BMD in the water fluoridated (WF) district, especially for females. It is assumed that the difference between two districts came somewhat from the effect of water fluoridation.

이 연구는 상수도수불화사업의 경제적 편익에 미치는 영향을 파악하기 위하여 2003년 1월 1일부터 6월말까지 상수도수불화지역인 청주시 상당구, 상수도수비불화지역인 안양시 만안구를 대상지역으로하여, 조사대상지역내의 치과의원에서 진료를 받은 진료지표를 비교 분석한 결과는 다음과 같다. 1. 상수도수비불화사업지역인 안양에서 상수도수불화사업을 실시할 경우 2003년 상반기의 6세에서 18세까지 연령에서 기대되는 치아우식증과 치수 및 치근단 주위조직 질환으로 인한 감소기대진료건수는 1,272건, 저추정시 636건, 고추정시 1,908건이 감소될 것으로 기대된다. 그리고 감소기대진료비는 40,888천원, 저추정시 20,444천원, 고추정시 61,333천원이 감소될 것으로 기대된다. 2. 상수도수불화사업의 전국 확대를 가정한 연간 기대건수는 2,492,018건, 저추정시 1,246,009건, 고추정시 3,738,027건이 감소가 기대되며, 감소기대진료비는 80,105,075천원, 저추정시 40,052,537천원, 고추정시 120,157,612천원이 각각 감소가 기대된다. 3. 급수인원이 48,925명인 영운정수장의 경우 편익/비용 비율이 2.9배이며, 급수인원이 239,751명인 지북정수장의 경우 편익/비용 비율이 9.0배이다. 상수도수불화사업은 급수인원이 증가함에 따라 비용의 증가는 미미하고 규모에 따른 경제 효과가 매우 크게 나타났다. 국민구강건강증진은 아울러 구강건강보험재정의 비용절감과 연관이 있다고 사료되며, 이를 위하여 전국 모든 지역에 상수도수사용을 확대 실시하여, 상수도수와 불소화에 대한 적극적인 홍보와 교육을 통한 신뢰 구축이 추가적으로 필요하다고 생각된다.

This work was based on the hypotheses that fingernail clippings can be used as a biomarker for the subchronic exposure to fluoride. This study was conducted to prove the hypotheses and fingernail clippings were collected form 120 preschool children aged $3{\sim}6$ residing in Jumunjin(community water fluoridation area) and Kangnung(non-fluoridation area). The acid-diffusible fluoride in the fingernail clipping was isolated by the acid-diffusion technique and measured with a fluoride electrode. The mean fingernail fluoride as the children's living area were 4.49ug/g(SD 2.43) to Jumunjin and 2.68ug/g(SD 1.13) to Kangnung. As would be expected, the fluoride concentration in fingernail clippings were significantly different between the two geographical groups(p<0.001) determined by t-test.

This study was conducted to determine the fluoride intakes in 120 preschool children aged $3{\sim}6$ residing in Jumunjin(community water fluoridation area) and Kangnung(non-fluoridation area). The parents duplicated all the diets that their children ingested in a day. The acid-diffusible fluoride in the diet was isolated by the acid-diffusion technique and measured with a fluoride electrode. The mean daily fluoride intakes form all kinds of diet by children residing in Jumunjin and Kangnung were $0.445{\pm}0.354mg/day$ and $0.131{\pm}0.097mg/day$, respectively. It is concluded from this investigtion that the amount of fluoride intake of children living in Jumunjin(fluoridated areas) did not exceed the upper intake level designated by the Institute of medicine of the US National Academy of Science to avoid the risk of dental fluorosis(2.2mg/day in 4- to 8-year-olds).

The purpose of this study is to provide basic information about oral health behavior of dental technology department students. Questionnaire surveys were conducted for 925 dental technology department student. Their knowledge and attitude towards oral health and health education services utilization were surveyed. The results obtained were as follows; 1. Ever thought most of the students recognized that oral health was an important health issue, there were more subjects who lowly regarded the level of the perceived self-oral health knowledge than who regarded highly. Female students were negative on the state of their oral health than male students. 2. On the water fluoridation program, 52.2% of the respondents replied that they do know well about the program and 44.1% of them supported the execution of the program. Female students approved of fluoridation program than male students. 3. Number of mean tooth brushing was 2.71 times a day, the most frequently exhibited time of doing tooth brushing was after taking a breakfast or before going to bed. 4. The students who had experiences of visiting dental clinics for the past 1 year were 47.7% and the purpose of visiting dental clinics for the last time was to conduct caries treatment.
