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.

Background: This study tries to compare and analyze the removal effect of dental plaque of general dentifrice and pregnant women's dentifrice and quantify the results to provide basic data so that consumers can make reasonable choices when purchasing dentifrice, and also increase interest in the dental plaque. Methods: After forming a dental plaque (carbohydrate porridge) on the labial surface of the bovine teeth, a disclosing agent was applied. Then the same experimenter brushed the surface of the bovine teeth using an electric toothbrush and took photographs using a DSLR camera. Thereafter, the residual amount of dental plaque was analyzed using the ImageJ program, and SPSS 26.0 was used for statistical processing. Results: The average residual amount of dental plaque using the general dentifrice was 11.71% for Perio, 9.45% for Cliden, and 8.47% for 2080, and the average residual amount for the three types was approximately 9.88%. The average residual amount of dental plaque of pregnant women's dentifrice was 13.95% for Jeninmothers, 12.53% for Tntnmoms, and 12.63% for Mommiracle, and the average residual amount of the three types was approximately 13.04%. On comparing the average residual amount of dental plaque between general and pregnant women's dentifrices, it was observed to be 3.16% higher for the latter. However, the results were not statistically significant. Conclusion: According to the research results, there was no significant difference in removal effects of general dentifrice and pregnant women's dentifrice. In addition, when a pregnant woman uses the right toothbrushing method with pregnant women's dentifrice, it can prevent or inhibit the progression of the gestational periodontal disease. Therefore, we recommend pregnant women to use pregnant women's dentifrices.

Objectives: The purpose of the study is to investigate the relationship between fluorine concentration within finger nails and the level of dentifrice in dental hygiene students and non-health majoring students. Methods: A self-reported questionnaire was completed by seventy female college students living in Daegu and Gyeongbuk that are not supplied with fluoridation from May to June, 2014. Informed consent was approved by institutional review board (IRB). The questionnaire consisted of general characteristics of the subjects (11 items) and oral health behavior including number of toothbrushing, duration of toothbrushing, number of mouth rinsing, and amount of dentifrice. A dentist and a dental hygienist examined directly the subjects by the guideline of World Health Organization (WHO). The oral examination included decayed tooth, healthy tooth, and filled tooth. The nail samples were obtained from seventy female students. Results: Comparing the dental hygiene students and non-health majoring students, 62.5% of dental hygiene students used approximately 1300mg of dentifrice and 55.2% of non-health majoring students used 1800mg or more of dentifrice. The non-health majoring students used more dentifrice (p<0.01). The fluorine concentration within nails was $1.9905{\mu}l/g$ in dental hygiene students and $3.2149{\mu}l/g$ in non-health majoring students. The fluorine concentration within nails in the dental hygiene students was significantly lower(p<0.01). Conclusions: The accumulation of fluoride in human body is not fully caused by dentifrice. However, The accumulation may occur due to toothbrushing so that it is necessary to educate the students about the right use of the dentifrice.

Objectives : The purpose of this study was to examine the amount of daily fluoride intake among children using fluoride-containing dentifrice in an effort to pave the way for the selection of criteria for the development of safe dentifrice for different age groups to make a contribution to children's oral health. Methods : This study was implemented over approximately six months from May to October 2008 by recruiting subjects, asking their consent, conducting a survey, collecting samples and analyzing the collected data. The subjects in this study were preschool residents in Seoul and Gyeonggi province, who were at the western age of 2 to 5. The amount of fluoride withdrawn from their one-time toothbrushing was measured in two different ways. One was by using HMDS-facilitated modified diffusion method and fluoride ion electrode, and the other was by applying ion chromatography without the diffusion procedure. Results : The fluoride intake accounted for $46.5{\pm}19.1$ percent of the amount of fluoride used, and that percentage was statistically significantly different according to age(p<0.01). The one-time fluoride intake from dentifrice per weight(kg) was a mean of $0.009{\pm}0.006mg$. As a result of multiplying this amount by daily toothbrushing frequency, the daily fluoride intake from dentifrice per weight(kg) appeared to be $0.023{\pm}0.016mg$ on average. There was a large difference among the children in that regard, since that ranged from a low of 0.003mg to a high of 0.070mg. And age made a statistically significant difference to that(p<0.01). Conclusions : The above-mentioned findings of the study showed that the children's daily fluoride intake from dentifrice per weight was lower than the recommended daily fluoride intake from diets per weight for young children aged 1 to 12(0.05-0.07mg). However, there was a great disparity among the children in that aspect, and they are likely to take more fluoride from other things as well. Therefore it is required to prepare separate criteria for preschool and school-aged children.

이 연구는 세치제 내 함유되어 있는 SLS의 함유여부에 따라 구강 내 타액과 세균수의 변화정도를 비교분석하여 향후 보다 양질의 세치제 개발을 위한 기초자료를 제공하고자 하였다. SLS의 함유량을 2.2%와 0.0%의 세치제를 제조하여 각각 30명으로 구성된 두 집단의 실험대상자에게 4주간 사용하게 하고 실험 전 후의 타액과 구강 내 세균 수의 변화 차이를 보았다. 연구결과 SLS의 배합여부는 타액, 세균수의 변화에 현저한 차이를 보이지 않았다. 또한 SLS 배합여부는 타액량과 구강 내 세균수의 관련성이 없는 결과를 보였다. 하지만 실험대상자들이 사용한 세치제에 대한 만족도 조사에서는 SLS가 함유되지 않은 그룹 보다 SLS가 함유된 그룹에서 만족도가 현저하게 높은 것으로 나타났다. 만일 SLS가 선호감 때문에 이용되고 있다면 SLS의 적정 함유량에 대한 구체적 개선방안을 모색하여 할 것이다.

Objectives : The purpose of this study was to examine the relationship of toothpaste-squeezing methods to the amount of toothpaste used among adults. Methods : The subjects in this study were 227 freshmen in a local college. After the intent of a survey was explained by this researcher, how much dentifrice they used was checked to ensure statistical objectivity, and then a survey was conducted. The collected data were analyzed with a SPSS WIN 13.0 program. Results : The findings of the study were as follows:1. As for connections between the way of squeezing and the amount used, the usual amount used, the amount used by horizontal squeezing and the amount used by pea-sized squeezing were respectively 1.12g, 0.66g and 0.46g. The amount used by horizontal squeezing and pea-sized squeezing was less than the usual amount used by 0.46g(41%) and 0.66g(59%) respectively.2. Gender, residential area, educational experiences and daily mean toothbrushing frequency made no differences to the amount of toothpaste used.3. The students who normally used a larger amount of toothpaste used a greater amount of toothpaste as well when they utilized horizontal squeezing and pea-sized squeezing, and the larger amount used by horizontal squeezing led to the greater amount used by pea-sized squeezing. Conclusions : As there were large disparities in the amount of toothpaste used according to the squeezing methods, systematic research efforts should be directed into setting the standard for the recommended amount of toothpaste used for adults and into squeezing method so that they could brush their teeth in an effective manner by using the minimum amount of toothpaste.
