Objectives : The purpose of this study was to examine the use of dentifrice for children, the state of dentifrice for children on the market and the relationship between the bore of dentifrice and the amount of dentifrice used in an effort to provide parents, main consumers of dentifrice for children, with the right information on dentifrice. Methods : Data on the use of children's dentifrice were gathered by investigating parents in Seoul and Gyeonggi Province in July and August, 2009. The selected parents had children aged one to five in Western age. Results : 1. As to the purchase of dentifrice for children, the largest group (75.9%) were aware of the name of the toothbrush used by their children, and the greatest group (97.3%) bought the toothbrush on behalf of them. Advertising was the most dominant source of information on the choice of dentifrice (51.8%), and non-professionals were the most common providers of information on that (55.9%). 2. The amount of dentifrice used at a time was a mean of $0.467{\pm}0.270g$. There was a wide disparity in that aspect from a low of 0.100 to 1.900g. As to the influence of the size of the bore of dentifrice, the greatest amount of dentifrice was used ($0.670{\pm}0.306g$) when the bore of dentifrice was 9 mm in size, and the bore size 9 mm was significantly different from the size 3 mm and 6 mm in that aspect (p<0.001). 3. There was one kind of imported dentifrice for children on the market. Concerning the fluoride ingredient of dentifrice, the biggest number of dentifrice contained MFP only. As to the size of the bore of dentifrice, there was a difference of 3 to 9 mm. Most of dentifrice for children included the pictures of particular characters. Conclusions : The above-mentioned findings illustrated that there is a serious concern for the intake of fluoride among infants and preschoolers, it's needed to pay careful attention to the use of dentifrice. Dentifrice for children should be manufactured in consideration of the relationship between the size of the bore and the amount of dentifrice used.

The purpose of the present study is to evaluate dimensional consistency, bristle finishes and bristle rebound rate of four brands of $Dentichek^{(R)}$ toothbrushes(regular-male, regular-female, soft-male, soft-female) to provide referneces in product enhancement and quality control for the manufacturer and to provide suggestions in selecting appropriate toothbrushes for general public. The results are as follows : 1. The size of the head is : $25.10{\times}8.10mm$ for male toothbrushes and $19.90{\times}8.10mm$ for male toothbrushes, while the size of the bristle portion is: $29.90{\times}10.65mm$ for male toothbrushes and $25.25{\times}10.65mm$ for female toothbrushes. 2. The length of the bristles is 10.70mm in all four groups. 3. The length of the toothbrush is 192mm in all four groups. 4. The number of tuft is 43 for male toothbrushes and 35 for female toothbrushes. Tuft arrangement is 4-row configuration in all four groups. 5. The number of bristles in a tuft ranges from 40-56, with higher numbers in male toothbrushes compared to the female counterparts, and higher numbers in the "soft" variety compared to the regular ones. 6. The diameter of the bristle is : 0.21mm for the outer row and 0.19mm for the inner row in the regular brand, and 0.17mm for the soft brand. 7. Irregularly finished bristle ends comprised 20-22% of the total bristles. 8. The bristle rebound rate ranges from 55.9% to 62.3%, with higher numbers in the "soft" variety compared to the regular ones. The above results show that $Dentichek^{(R)}$ toothbrushes meet the requirements of Korean Dental Association standards for toothbrushes, but further evaluations of their effects on periodontium and plaque elimination in actual in-use situation may be needed.

Objectives : This study was carried out with the aim of utilizing it as basic data in a plan for oral health promotion by analyzing oral-health awareness in high school students of some districts in our country, and by analyzing physical, mental and social influential factors in oral health, through using OHIP(Oral Health Impact Profile). Methods : It surveyed by carrying out self-administered questionnaire research targeting 536 boy & girl high school students in the 1st and the 2nd grade at 3 high schools in some districts of Gyeonggi Province. Results : 1. As for experience of having not visited dental clinic, a case of having not visited accounted for 32.5%. On the other hand, a case of having visited accounted for 67.5%. As for the appearance of oral health education, only 2.8% responded as saying of having experience. 97.2% responded as saying of having not taken oral health education. 2. As for oral health state perceived by oneself, the response as saying of 'thinking it to be healthy' and that 'there is something wrong' showed the distribution of 34.1% that is the same ratio. As for oral health interest, a case of having a little interest(58.4%) or of being so much interested(12.5%) showed 70.9%. A case of having no special interest(24.8%) or of having no interest at all(4.3%) showed the level of 29.1%.3. As for oral health knowledge, the toothbrushing knowledge was the highest with 4.54 marks out of 6-point perfection. The toothbrush knowledge(4-point perfection) showed low point with 2.05 marks. 4. By gender, a case of men was high in OHIP(Oral Health Impact Profile) for the functional restriction and physical pain. On the other hand, in the remaining sphere, women were indicated to be high in OHIP. The statistically significant difference was indicated in the spheres such as physical pain, psychological discomfort, a drop in psychological ability, a drop in social ability, and social separation. 5. According to oral health state perceived by oneself, a case of thinking it to be healthy was indicated to be high in OHIP for every sphere. A case of thinking it to have gum disease was indicated to be low in OHIP for every sphere. The statistically significant difference was indicated in every sphere except the sphere of functional restriction. 6. As for a factor of having influence upon OHIP according to oral health knowledge, it was indicated that the higher toothbrush knowledge leads to having more influence upon OHIP. Conclusions : It could be known that the oral health knowledge and OHIP are varied as well according to the oral health interest level. Also, the oral health education proper for subjects is not being performed. Even as for frequency of visiting the dentist, a regular visit is failing to be made. In consideration of these points, the diversified and effective educational program is likely considered to be necessarily developed and improved that subjects can have more interest in oral health.

The purpose of this study was to provide information on the development of an oral-health promotion program geared toward office workers. The subjects in this study were 240 employees at the headquarters of S construction company. After a survey was conducted in July and August 2008, the answer sheets from 208 respondents were gathered, and 191 answer sheets were analyzed except 17 unanalyzable ones. The findings of the study were as follows: 1. In regard to subjective oral health status, the largest number of the participants that accounted for 37.2% found their mouth to be neither healthy nor unhealthy. The greatest number of them that represented 58.1% had never visited a dentist's office to receive preventive treatment. 2. Regarding relationship between toothbrushing education experience and toothbrushing frequency, the most common toothbrushing frequency was three times a day( 46.5%) among the company employees who had ever received that education. In the event of the office workers without that experience, the most prevalent frequency was three times(63.6%). The toothbrushing frequency was statistically significantly different according to the toothbrushing education experience(p<0.05). As to the relationship of toothbrushing education experience to tooth- brushing method, the largest number(48.2%) of those who had ever received that education brushed their upper and lower teeth along with the gums by rotating the toothbrush downward from the top and upward from the bottom respectively. In the event of the office workers without that experience, 49.4 percent brushed their teeth and gums by rotating the toothbrush up and down. Thus, whether they had ever received education about toothbrushing made a statistically significant difference to their toothbrushing method(p<0.05). 3. As a result of evaluating their oral health belief by utilizing a five-point scale, they got a mean of 2.95. In each area of oral health belief, they got the best marks in benefit(3.66), salience(3.42), barrier(2.84), susceptility(2.58) and seriousness(2.23). Given the above-mentioned finding of the study, two sorts of oral health beliefs, which are benefit and salience, should be stressed in the development of oral health education programs that cater to company employees. And sustained research efforts should be channeled into finding out the relationship between oral health and actual oral health care.

장기적인 칫솔질시 외부 stain 처리된 IPS e.max Press 도재의 색의 변화를 분광측색장치(SpectroShade$^{TM}$)를 이용하여 측정하고 비교함으로써 외부 stain의 색 안정성을 평가해 보고자 한다. IPS e.max Press LT ingots shade a1(Ivoclar Co.,Liechtenstein)를 사용하여 블록 형태의 시편을 제작하였으며 Orange, A, B, C, D shade로 외부 stain 처리 하였다. 칫솔질 기계를 이용하여 1년(11,000회), 2년(22,000회), 4년(44,000회), 6년(66,000회), 8년(88,000회) 치의 칫솔질 운동을 수평적으로 시행하였다. SpectroShade$^{tm}$ MICRO(MHT, Italy)를 이용하여 색조 변화를 측정하였다. 1년치(11,000회)의 칫솔질 연마 후 Orange shade에서 다른 4개의 shade보다 더 크게 색 차이가 나타났다. 그 후 칫솔질 횟수가 증가하여도, 외부 stain의 shade에 따른 색 차이의 변화는 통계적으로 유의성이 없었다. 칫솔질의 횟수의 증가에 따른 색 차이의 변화량은 일정한 증가나 감소의 경향을 보이지 않고 불규칙하였으며 통계학적으로 유의한 차이가 발견되지 않았다. 칫솔질이 IPS e.max Press 도재의 외부 stain의 변화에 크게 영향을 미치지 않으며 임상적으로도 외부 stain의 색 안정성이 인정된다고 생각된다. 추후 외부 stain에 영향을 미칠 수 있는 다른 요인들에 대한 연구도 필요하리라 사료된다.

The purpose of this study was to develop a standardized preschool oral health education program as one of educational media and to apply it to preschool education. It's ultimately meant to help improve the oral health education policy of the nation toward young children and to provide multiple information on that. The subjects in this study were 250 young children who were at the age of 7 and attended kindergartens in the city of S. To evaluate an oral health education program prepared in the study, the selected young children were taught by using it, and a survey was conducted twice before offering education and three weeks after it to assess their knowledge. Besides, their patient hygiene performance was tested. For data handling, SPSS program was utilized, and in order to see if there would be any changes in their oral health behaviors, statistical data on percentage were obtained and crosstab was employed. To track any possible additional changes in their relevant knowledge and Simplified Oral Hygiene Index, t-test was implemented. The findings of the study were as follows: 1. As for changes in oral health behaviors, there were significant differences in tooth brushing time(p<0.05), tooth brushing method(p<0.01) and toothbrush keeping method(p<0.001) between before and after the education. 2. Regarding changes in oral health knowledge, there was a significant gap between before and after the education(p<0.001). In detail, their knowledge about the cause of dental caries(p<0.05), the right choice of toothbrush(p<0.001) and toothbrushing after meals(p<0.01) became significantly different. 3. There was no gap in patient hygiene performance index between before and after the education. 4. To boost the effect of oral health education on kindergarteners, it seems necessary to give a lecture on oral health, to demonstrate tooth brushing by using dntiform, and to offer instruction by utilizing disclosing solution. 5. Repeated education should be provided on a regular basis by preparing standardized teaching plans tailored to the characteristics of kindergarteners, and a wide variety of teaching materials that could be easy to understand, authentic and provide motivation to them should be developed.
