수돗물 불소화사업이란 치아우식증 (충치)을 예방할 목적으로 0.8ppm의 불소를 수돗물에 첨가하는 공중보건사업이며, 수돗물 불소화사업이 시행되지 않고 있는 서울시내 초등학교에서는 1995년부터 불화나트륨용액 (0.2%용액으로 매주 1회 또는 0.05%용액으로 매일 1회)으로 불소양치를 실시하고 있으며, 서울시 일부 보육시설에서는 만4세-6세의 취학전 아동을 대상으로 불소용액양치사업 (0.25% 용액)을 1997년부터 실시하고 있다. (중략)

The purpose of this study was to evaluate the efficacy of gargle and toothpaste containing low concentration with sodium fluoride on the remineralization through the surface microhardness and mineral content in enamel. After 4 weeks-application, the enamel surface was measured using microhardness tester and the calcium (Ca) and phosphorous (P) concentration of mineral content by electron probe microanalyzer (EPMA) analysis. By combining fluoridated gargle with toothpaste, a remineralized enamel resulted in significantly significant differences among the four groups (p<0.05). The Ca change treated with 0.23% fluoridated toothpaste and 0.02% fluoridated gargle with 0.23% toothpaste demonstrated the highest among the other groups. In conclusion. the fluoridated gargle with toothpaste by low concentration showed a significantly greatest synergistic effect on remineralization of the enamel than the other groups.

The purpose of this study was to evaluate caries preventive effects of a school-based weekly mouthrinsing program with a 0.2% sodium fluoride solution for five years at elementary school in Yangsan city, which were conducted for 330 children of elementary school from 2000 to 2005. The surveyed data was analyzed with SPSS statistical package. The obtained results were as follows; 1. DMF rate was 58.4% before the mouthrinsing program in 2000 and 48.3% after the program in 2005. DMF rate in 2005 decreased by 10.1% compared to DMF rate in 2000. 2. DT index was 2.46 before the mouthrinsing program and 1.70 after the program. DT index in 2004 decreased by 0.76 compared to DT index in 2000. 3. FT index was 0.55 before the mouthrinsing program and 0.37 after the program. Filled teeth due to decay after the program decreased by 0.18 compared to filled teeth before the program. 4. DMFT score was 2.61 before the mouthrinsing program and 1.64 after the program. DMFT score in 2004 decreased by 0.97 compared to DMFT score in 2000. 5. PHP index was 12.12 before the mouthrinsing program and 5.95 after the program. PHP index in 2005 decreased by 6.17 compared to PHP index in 2000.

In order to develop the program of oral hygiene education for elementary school senior-students, a questionnaire survey of elementary fourth, fifth and sixth students who are under continual control program of oral hygiene. (1) For tooth brushing time, after dinner is more than before. 73.7% of respondents brushed the teeth twice or more a day. (2) 62.1% of respondents took the cariogenic food twice or more a day. (3) 90.1% of respondents had visited a dental clinic. (4) Concerning fear for dental treatment, only 14.4% had a feeling of fear. (5) Regarding the experience with a preventive treatment, 39.7% had an experience with pit and fissure sealing, and 24.2% had an experience with the application of fluorides. (6) 46.2% of respondents had a preference for the fluoride mouth rinsing program, and 38.4% wanted that program to keep going on. As to the reason to favor the fluoride mouth rinsing program, 38.2% preferred it because of prevention of dental caries, and 43.0%, the largest percentage, didn't favor it because they found it too much trouble to do. (7) Comparing with the research result in 2000, we proved positively the educational effect of brushing frequency, positive understanding and preference to water school fluoridation program, and got the negative data of experience of visiting to oral clinic and preventive treatment.

Objectives : The purpose of this study was to investigate the possible differences in elementary schools jointed to fluoride mouth rinse plans in health centers. Methods : Students from the third to sixth grades filled out the questionnaires. Data were analyzed by the statistical package SPSS 12.0. Results : The rate of a personal toothbrush holding and toothbrushing after lunch were higher in those who rinsed their mouths with fluoride than those who did not.(p<0.05). Toothbrushing by the rolling method was more prevailing in the students who rinsed their mouths with fluoride(57.0%) and having regular dental checkup(p<0.05) than in those who did not(39.8%). Conclusions : The students who had rinsed their mouths with fluoride showed the good oral health behavior. Continuing good quality of oral health care education must be provided to the students by professional dental hygienists.

지난 6월 30일까지 각 시ㆍ도 초등학교는 교육법 학교신체검사규칙에 따라 신체검사를 실시했다. 구강검사는 신체검사 중 체질검사에 속하는 것으로서 초등학교에서 실시하는 구강보건사업 중의 하나다. 현재 학교구강보건사업으로는 구강검사 외에도 불소용액양치사업과 구강보건교육 등이 있으나 많은 관계자들은 학교에서 실시하는 구강보건사업에 어려움을 호소하고 있다. 이에 초등학교에서 실시하는 구강보건사업의 현황과 함께 문제점과 대책에 대해 살펴본다.

Fluoride use is the best and widespread method for dental caries prevention. The aim of this study was to investigate experience and recognition of fluoride for caries prevention focusing on majors in one university. Four hundred twenty-four university students were selected by convenience sampling with informed consent and answered the questionnaire by self recording type. The subjects except dental hygiene students knew about purpose of fluoride use (84.6%), over the count fluoride rinse (63.2%), fluoride toothpaste (61.5%), professional fluoride application (56.4%) and water fluoridation (43.6%). They experienced over the count fluoride rinse (67.5%), school fluoride rinse (45.3%), professional fluoride application (30.8%), fluoride toothpaste (28.2%) and water fluoridation (12.0%). The main information paths about fluoride were university lectures among dental hygiene students and internet and mass media, followed by nurse-teachers among non dental hygiene students. The ratios of intention to use fluoride were: 67.8% in dental hygiene, 34.9% in health, 51.4% in non-health in case of professional fluoride application for oneself, 93.1% in dental hygiene, 48.0% in health, 50.4% in non-health in case of professional fluoride application for their children, 79.0% in dental hygiene, 51.3% in health, 55.8% in non-health in case of water fluoridation. The subjects to experience and recognize fluoride for caries prevention had more positive intention to use fluoride. The answers of students majoring in health or medical care were not different from non-health, except dental hygiene. Dental professionals should try to let the public know about fluoride use for caries prevention through mass media and internet as well as individual education in dental clinics.

Through out the world dental caries seems to be decreased as it is difficult to make an accurate diagnosis for dental caries. The traditional diagnostic method which is probing and x-ray taking has many limitations to diagnose the early caries, so there were recommendations for the needs of new equipments such as laser fluorescence(LF), digital imaging fiber-optic trans-illumination(DIFOTI), and quantitative light fluorescence (QLF) which were developed from various study results. Also confocal laser scanning microscopy(CLSM) and ultrasonics are used for research progression. This study is to evaluate whether it is possible to monitor accurately for remineralization amount of enamel surface early caries using DIFOTI or LF After inducing artificial caries to bovine teeth to 10 participants remineralization was enhanced by 0 ppm and 500 ppm fluoride mouth rinse solution for 3 weeks. Then they were cross sectioned and analyzed using gold standard of the lesion depth measured by CLSM. The following results were obtained: 1. The measured percentage of light intensity(luminosity ratio) by DIFOTI increased with remineralization period, and showed significant reverse correlation with lesion depth measured by CLSM (p<0.01). 2. The measurement of laser fluorescence increased with remineralization period, and showed significant correlation with lesion depth measured by CLSM (p<0.01). 3. To the result for CLSM, 500 ppm fluoride mouth rinse group showed rapid rate for decreased tendency of lesion depth than 0 ppm fluoride mouth rinse group. In conclusion DIFOTI system was used to measure accurately for the remineralization amount of early surface caries, it is a very useful equipment to detect precisely the changes for early enamel caries remineralization during treatments.
