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 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.

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.

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.

The purpose of this study was to provide basic data for oral health promotion of service worker and their effective interpersonal relationships forming through the evaluation about service workers' awareness of the auxiliary oral hygiene devices and using behavior of it. The survey was carried out questionnaire research targeting 400(service group 200, non-service group 200) and compared the two groups. The obtained results were as follow: 1. brushing behavior showed the highest ratio of 3~4 times/day(53.4%) in brushing frequency, up-down method(50.8%) in brushing method, after 5 minutes after the meals(45.0%) in brushing time, shape brush(56.6%) in brush change time. 2. service group used a lot more auxiliary oral hygiene devices than non-service group(50.9%). the frequency of use was toothpick(30.9%), gargle(29.9%), floss(13.5%), tongue cleaner(10.1%). 3. In comparison of two group about state of use, service group showed more higher ratio of floss(66.1%), tongue cleaner(64.4%), gargle(56.6%) than non-service group. non-service group showed more higher ratio of toothpick(54.6%) than service group 4. Service group used auxiliary oral hygiene devices by suggestions of dental clinic(53.6%) and didn't use them because of uncomfortable to use(45.4%) or didn't know how to use(21.6%). 5. As result of the awareness-related using rate of auxiliary oral hygiene devices, service group showed higher using ratio except toothpick than non-service group. especially gargle(54.8%), tongue cleaner(43.3%), floss(35.8%) were showed high. 6. service group took a regular checkups more than non-service group and showed the highest ratio of each 1 year(43.5%) in checkup period.

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.

국민의 구강건강을 보호 증진시켜, 궁극적으로 복지사회를 실현시키기 위한 구강보건사업은 대상에 따라 모자구강보건 사업, 학교구강보건사업, 성인구강보건사업, 노인구강보건사업 등으로 분류할 수 있다. 그리고, 이들 구강보건사업 중에서 특히, 학교구강보건사업은 앞으로 우리나라의 주빈이 될 2세 국민을 대상으로 한다는 점과 또한, 구강에 빈발하여 구강건강장애를 많이 유발시키는 중대 구강병인 치아우식증과 부정교합은 국민학교 학령기에 빈발하고, 치주병도 치은염으로 국민학교 졸업기에 대개 발생되어, 일생의 구강건강기틀은 국민학교 학령기에 마련된다고 보아야 하므로, 구강보건사업 중에서도 학교구강보건사업이 가장 우선적으로 개발 추진되어야 한다.

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.
