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 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.

This study aimed to evaluate the effects of oral rinsing solution on the color stability, surface microhardness and surface roughness change of composite resin. In this in-vitro study, 80 disc-shaped specimens were fabricated of Filtek P60 and Filtek Z250(A2 shade). The samples of each group were randomly divided into eight subgroups (n=10). The baseline color values ($L^*$, $a^*$, $b^*$) of each specimen were measured according to CIE LAB system using a colorimeter. After baseline color measurements, the control samples were immersed in distilled water and the test groups were immersed colorless, green and purple mouthrinses three times a day for thirty minutes. This process was repeated for two weeks. Green and purple oral rinsing solutions displayed color, microhardness and roughness change of all composite resin after immersion in the mouthrinses. Therefore, prescription of oral rinsing solution for a minimum of two weeks is a common practice, which may cause discoloration of aesthetic composite restorations of patients.

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 aims of this study were to evaluate the effect of native acidity upon dental hard tissues by measuring pH in mouth-rinse, which is on the market, and to evaluate even influence of dental stain caused by mouse-rinse given using for a long time. The experimental group was used Garglin, Nextcare, Listerine, and Hexamedin. The control group was used sterile distilled water. As a result, pH was indicated to be low in Nextcare(4.70) and Listerine(4.16). In a change of color tone, $b^*$ value of indicating Yellow-blue showed the lower value than the early color tone in all groups. There was statistical significance in Nextcare and Listerine. ${\Delta}L^*$ value of indicating light -dark gets darker after using Nextcare, Listerine and Hexamedine. A change(VHN) in surface hardness of enamel showed reduction in surface hardness after 14 days in Nexcare and Listerine. As a result of confirming a change in enamel surface by using Scanning Electron Microscopy, the erosion aspect on the enamel surface could be confirmed in groups of Nexcare and Listerine. Ra value in surface roughness of enamel could be observed the enamel surface, which got rougher compared to other experimental groups.

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.

1940년대부터 1970년대까지 치주치료의 목적은 복잡핞 치주외과적 수술을 통하여 치주낭을 제거 또는 감소시키는 것이었다. 그러나 1960년대와 1970년대에 이루어진 연구 결과를 보면 치주질환의 병인발생에 있어서 치태의 역할과 적절한 구강위생의 중요성이 강조되었다. 즉 치태를 제거하기 위해서 치솔과 치약, 그리고 보조기구를 이용한 구강위생방법(기계적인 처치)과 전신적 및 국소적 항생제투여, 그리고 양치용액의 사용(화학적인 처치)과 같은 비외과적 처치방법이 관심의 대상이 되었다. 여기에서는 치태를 효과적으로 관리하기 위한 기계적인 치료방법과 화학적인 치료방법에 대해 살펴보고자 한다.

The aim of this study is to clinically evaluate the effect of a mouthwash containing cetylpyridinium and zinc chloride on reduction of morning oral malodor in healthy subjects measured by organoleptic measurement and a portable sulfide monitor. A total of 8 healthy non-smoking male volunteers were enrolled in this study of crossover design consisting of two experimental phases. The subjects were instructed to rinse the mouth with 10 mL of the experimental mouthwash containing cetylpyridinium and zinc chloride for 30 seconds at the first phase. At the second phase after a one-week washout period, each subject rinsed with distilled water as a control. All experiments were conducted at around 8:30 a.m. and oral malodor was measured using organoleptic measurement and a portable sulfide monitor just before rinsing with the experimental mouthwash or control (baseline), 1 hr, 2 hrs, and 3 hrs after rinsing. The mouthwash containing cetylpyridinium and zinc chloride reduced morning oral malodor up to 3 hrs after rinsing. Organoleptic score and concentrations of volatile sulfur compounds after use of the experimental mouthwash significantly decreased with time, and the decreases were significantly different between the mouthwash and control. In conclusion, the mouthwash containing cetylpyridinium and zinc chloride is significantly effective on reduction of morning oral malodor in healthy subjects by 3 hrs.
