Background: Dental caries in preschool children can cause early loss of teeth, reduced masticatory function, malocclusion, and speech disorders, making oral care for preschool children essential. However, because children have a poor ability to perform oral hygiene by themselves, educational tools that help establish correct oral health behaviors are required. This study evaluated the effect of toothbrushing application for kids on dental plaque removal and toothbrushing interest in preschool children. Methods: Seven 5-year-old children enrolled in a daycare center participated in the evaluation, and the same children participated in the experiment twice a week. The Pokémon Smile application (App) was used as an auxiliary application for tooth brushing, and the degree of dental plaque removal on the tooth surface was evaluated by quantitative light-induced fluorescence-digital imaging. After the experiment, children's toothbrushing preferences were investigated through interviews. Results: The levels of AREA R30 and AREA R70 measured after the children's toothbrushing as usual decreased compared to those before toothbrushing; however, the change was not significant. The levels of AREA R30 and AREA R70 measured after using the Pokémon Smile App were significantly reduced compared to those before toothbrushing. Children's interest in brushing their teeth increased by 28.59% after using the Pokémon Smile App. Conclusion: The toothbrushing application for kids effectively removes dental plaque by helping preschool children brush their teeth. It also increased preschool children's interest in tooth brushing. Therefore, an oral health education application would be useful for children who need to develop correct oral care methods and habits.

본 연구의 목적은 법랑질 시편에 수종의 불소 제재를 도포한 후 우식 예방 효과를 광밀도 및 미세경도 측정을 통해 평가하는 것이다. 소의 절치를 이용하여 80개의 법랑질 시편을 제작하고 각 군당 20개씩, 네 군으로 나누었다. I군은 대조군으로서 아무런 처치도 하지 않았고 II군은 acidulated phosphate fluoride(APF) gel(60 seconds $taste^{(R)}$, PASCAL, USA)을 4분간 적용한 후 수세하였다. III군은 Fluor $Protector^{(R)}$(Ivoclar Vivadent, Liechtenstein)를, IV군은 $CavityShield^{TM}$(Omnii Pharmaceuticals, USA)를 1분간 도포하고 증류수에 보관한 뒤 24시간 후 부드러운 모를 가진 칫솔을 이용하여 칫솔질하였다. 각 시편을 인공우식용액에 48시간동안 침잠시켜 인공우식병소를 유발한 후 광밀도를 컴퓨터 영상분석 프로그램으로 분석하고 표면미세경도를 측정하여 다음의 결과를 얻었다. 1. 광밀도는 APF gel을 도포한 II군에 비해 불소 바니쉬를 도포한 III, IV군이 높았으나(p<0.05) III군과 IV군 사이의 유의한 차이는 없었다. 2. 표면미세경도는 IV군, III군, II군, I군의 순으로 높았다(p<0.05). 3. $CavityShield^{TM}$를 도포한 IV군과 Fluor $Protector^{(R)}$를 도포한 III군은 광밀도에서는 유의한 차이가 없었으나 표면 미세경도는 IV군이 III군보다 유의하게 높았다. 이상의 결과를 종합해 볼 때 불소 바니쉬가 APF gel에 비해 법랑질 탈회 억제 효과가 우수한 것으로 나타났다. 임상적용의 용이성과 안전성을 고려할 때 불소 바니쉬의 사용이 영유아나 장애인에게 유용할 것으로 사료된다.

Objectives : This research analyzed the general characteristics that closely affect the children's dental health and the mothers' dental health knowledge and dental health behavior to identify the correlation of the latter with the status of children's dental health in order to provide the basic data for the development of dental health business that would target children. Methods : Research subjects were selected arbitrarily from three nursery schools located in Busan metropolitan city, targeting 186 children between the ages of four to six and their mothers. The children were subjected to dental Inspection, and the status of their dental caries was studied whereas the mothers were subjected to the surveys on the general characteristics, dental health knowledge and dental health behavior. Results : 1. Level of mothers' dental health knowledge is higher when the mothers' educational level is higher(p=0.02) and when the household's monthly income is higher(p=0.009). 2. When the level of mothers' dental health knowledge is higher, children tended to brush their toothbrushing using proper method(p=0.025). Moreover, when the level of mothers' dental health knowledge is higher, they tended to take their children to dental clinic mostly for preventive measures than for treating cavity(p=0.023). 3. When the level of mothers' dental health knowledge is higher, children's dmft index was significantly low(p=0.02). When the mothers use fluoride-containing toothpaste, children's children' dmft index was even lower(p=0.02). 4. As the children tended to brush their teeth more often, dmft index was lower(p=0.003). When the reason that the children visited dental clinic was more to prevent, than to treat cavity, dmft index was even lower(p=0.000) Conclusions : When the above mentioned results are summarized, it is possible to know that the mothers' dental health knowledge and dental health behavior significantly affect children's dental health. Accordingly, it is necessary to develop maternal and child dental health program that factors in both the mothers and children in order to prevent children's dental caries and to increase their dental health, and continued care is required to discover and treat dental caries early on.

Objectives: The purpose of this study was to identify the related factors of dental caries and periodontal disease in adolescents from Korean multicultural families, thereby helping to reduce the prevalence rate of oral disease. Methods: The subjects were 710 multicultural adolescents recruited using a web-based survey, National 2015 Korean Youth Risk Behavior, from the Korean Center for Disease Control. A multicultural family was defined in this study as one having an immigrant mother or father. Oral symptoms included dental caries and periodontal disease. Toothache was defined as a symptom of dental caries. Tender or bleeding gums were defined as symptom of periodontal disease. For statistical analysis, Statistical Package for Social Sciences (SPSS) Version 21.0 for Windows was used. Descriptive analysis and a Chi-square test were conducted to determine the factors associated with general characteristics, health behavior, and oral health behavior. Finally, to investigate the associations among oral disease symptoms, logistic regression analysis was performed. Results: Toothache was significantly higher in female 1.52 (95% CI; 1.45-1.60), high school 1.23 (95% CI; 1.18-1.28), women school 1.10 (95% CI; 1.05-1.16), individuals with poor economic status 1.45 (95% CI; 1.30-1.52), and participants who consumed alcohol 1.32 (95% CI; 1.27-1.37). Toothache related to perceived health status was significantly lower in the healthy group 0.69 (95% CI; 0.64-0.75), and was higher in usual stress group 1.65 (95% CI; 1.57-1.74). Gum bleeding was significantly higher in female 1.32 (95% CI; 1.27-1.37), high school 1.15 (95% CI; 1.10-1.19), and individuals with poor economic status 1.38 (95% CI; 1.27-1.50). Gum bleeding related to perceived health status was significantly lower in the healthy group 0.68 (95% CI; 0.63-0.74), and was higher in usual stress group 1.54 (95% CI; 1.46-1.62). Conclusions: Taking into account of social and economic levels, and dietary habits in the multicultural families adolescents, further education and support will be needed for oral disease prevention and early treatment.

Objectives: This study was conducted to reveal the biological basis of dental plaque and preschool children's dental health status through repetitive and continuous toothbrushing instruction to preschool children, using quantitative criteria, and to emphasize the importance of the role of an oral health manager for the prevention of dental caries. Methods: After IRB approval, toothbrushing instruction and oral microbial specimen collection were conducted with children of preschool age at the Daycare Center attached to D. University, Busan. Specimens from 27 children were characterized by analysis with real-time multi-chain enzymatic polymerization reaction technique at an agency specializing in genetic analysis. Results: In a survey of the children's dental health behaviors, 48.1% responded that the toothbrushing time is 91 to 150 seconds; 66.7% responded that the frequency of toothbrushing is more than three times per day; 81.5% stated that they performed tongue brushing; and 81.5% brushed their teeth. Regarding levels of dental cariogenic bacteria, after children received continuous toothbrushing instruction, there were reductions in both Streptococcus mutans and Streptococcus sobrinus. Regarding toothbrushing time, the time increased in relation to the presence of instruction. Regarding Quigley Hein Index, the index decreased in the early and middle periods upon addition of instruction, then increased in the middle and later periods. Conclusions: Through persistent and repetitive toothbrushing instruction, healthy behavior can be positively established in children of preschool age; it is necessary to prepare institutional measures so opportunities for dental health education can be consistently provided and maintained. In the future, it will be necessary to conduct a follow-up study to verify the factors affecting toothbrushing time and volume of oral pathogens.

This study was peformed in order to find out the relationship between the causing factors and the production of each gas 01 oral malodor, to contribute the oral malodor control at dental clinic as well as to establish the effective application of malodor control project for public oral health program 127 patients from 20 to 40 years old who had been visited for preventive dental cares were participated for the study. Such items as caries status, periodontal status, salivary flow, viscosity, pH. Snyder test, plaque deposit and tongue plaque were checked through the oral examination in order to find out the contributing factors Hydrogen sulfide, Methyl mercaptan, Di-methyl sulfide and Ammonia gas components were checked with Oral-Chroma and Attain, the oral malodor check units. Not only the corelation coefficiencies but also the multi-way variance analysis were calculated between each causing factor and each component of oral malodor gases to estimate the contributing factors of the oral malodor. 1. There was no relationship between the caries status and each component pf the oral malodor such as sulfur compound or Ammonia, both in laboratory test and VAS test (pF0.05). It revealed negative relationship between Hydrogen sulfide and FT(rM-0.1904. pE0.05) as well as the VAS and FT (rM-0.210. pE0.05). S0, it was estimated that the less oral malador was recognized when caries state changed to filled state in Hydrogen sulfide laboratory test or VAS test 2. High relationship was showed between salivary flow and Hydrogen sulfide (rM-0.183, pM0.039), Methyl mercaptan(rM-0.234, p-0.008). Dimethyl sulfide(rM-0.234, pM0.008) and Ammonia(-0.361. pM0.001) gas(pE0.05). 3. There was a high relationship between M-PHP(Modified-Patient Hygiene Performance Index) and tong plaque all kinds of sulfide(rM0.249. pM0.005). Ammonia gas component(rM0.232, pM0.009). 4. It was found that considerable relationship was appeared between the periodontal status and Ammonia gas (rM0.274, pM0.002), so, it should be needed to control Ammonia. Such dental Cares as the prevention or early treatment of periodontal disease and the accelerating the salivary flow as well as reducing the amounts and activities of filament or spiral typed oral micro-organism were recommended for adults, not only for dental care program at the dental clinics but also for public health programs, in order to promote the oral health and quality of file for individual and community peoples.

치아 우식증은 구강 영역에서 가장 흔한 질환이나 여러 가지 복잡한 요소가 작용하기 때문에 이에 대한 발생기전과 치료법에 대해서는 완전히 이해되지 않은 상태이다. 특히 초기우식의 재광화에 있어서 pH의 영향에 대하여 논란의 여지가 있다. 본 연구에서는 유산 완충용액을 이용하여 상아질에 인공 우식을 형성하고 이때의 무기질 소실을 측정하고, 탈회된 시편을 pH가 다른 세 가지 재광화 용액 (pH 4.3, 5.0, 5.5 군)으로 재광화시켰을 때 나타나는 무기질의 침착되는 양과 침착이 일어나는 부위를 Microradiograph를 이용하여 정량적으로 비교 분석하였다. 또한 주사전자현미경을 이용하여 수산화인회석 결정의 정상 상태 탈회된 상태, 그리고 재광화가 일어났을 때의 상태를 정성적으로 비교하여 다음과 같은 결과를 얻었다. 1. Microradiograph분석시 pH가 증가할수록 탈회된 상아질에서 재광화양이 유의차 있게 증가되는 경향을 보였고, pH가 낮아질수록 재광화가 일어나면서 더 깊게 탈회되는 양상을 보였으나, pH 5.5 군은 전반적으로 재광화가 일어나는 경 향을 보였다 (p<0.05). 2. 주사전자현미경 소견에서 상아질 우식의 재광화는, 유기기질 망을 둘러싸고 있는 수산화인회석 결정의 표면으로부터 진행되며 결국에는 탈회 시 파괴된 공간을 채워가는 양상으로 관찰되었다. 3. 재광화 5일 후 pH 4.3. 5.0군에서 무기질이 침착되어 수산화인회석결정이 정상보다 커졌으며, pH 5.5군에서 재광화된 부위의 결정은 정상으로 회복되는 양상을 보였다. 재광화 10일 후 pH 4.3, 5.0 군에서 재광화 5일 후에 정상보다 커졌던 결정들이 정상상아질의 결정 크기로 줄어들었으며 pH 5.5군에서는 결정의 크기가 2배정도 커진 경우도 관찰되었다. 본 실험의 결과에 의하면 상아질의 우식과 재광화 과정은 단순한 탈회와 재광화의 독립적인 과정이 아니고 동력학적으로 탈회와 재광화가 동시에 일어나는 과정이며, 이때 재광화는 기존의 수산화인회석 결정의 표면으로부터 진행되었다.

Most of disabled people face hardness in caring their general oral hygiene by themselves. So that, they are once involved in dental caries or periodontal disease, they have much bigger chance of aggressive progress. Therefore preventive dentistry is more important to disabled one than non-disabled. They need to be checked with routine periodic dental examination and by that, oral disease must be found at initial stage. We selected 37 patients from newly visited 237 patients who had dental treatment at the free dental clinic, Gangnam district, Seoul, between 2000 and 2001. This study is a comparative evaluation of first 2 years' treatment records of selected 37 patients (male 28, female 9) with that of their last 2 years. 24 of 37 have mental retardation, 9 have autistic disorder, 2 have auditory disorder, 1 has brain disorder and 1 has crippled disorder. Their dental treatment records categorized by 4 level; score 4 stands for endodontic treatment, score 3 stands for general conservative treatment, score 2 stands for preventive treatment, such as sealant and score 1 stands for routine check. In first 2 years of treatment, average score was 2.85 which score means approximately general conservative treatment. And that of last 2 years was 1.44, which means routine check. In early time of their visit, they will receive the treatment due to their chief complaint. And after that early time, they can have a routine check so that they can be treated before the disease get worse. The patient's oral health can remain decent only by a simple treatment.
