본 연구는 치면열구전색 하방의 우식이 이차우식에 미치는 영향을 평가하기 위해 DIAGNOdent를 이용하여 소구치 및 대구치 교합면 446부위를 4개의 군으로 분류하였고 상방에 치면열구전색을 시행한 뒤 이차우식을 유발시켜 DIAGNO dent로 재측정하였다. 또한 치과 업무 관련 종사자들을 대상으로 치면열구전색에 대한 인식도 및 실태를 조사하여 다음과 같은 결과를 얻었다. 시진 및 탐침 시 법랑질우식군에서 치면열구전색 후 이차우식이 가장 높게 나타났으며 초기우식군, 착색군, 건전부위군 순으로 통계적으로 유의한 차이를 보였다(p<0.05). 치면열구전색 전 치아우식증 진단 방법으로는 시진이 가장 높은 비율로 나타났다. 레이저 우식진단기에 대해 56.6%가 모르는 것으로 나타났으며, 91.6%가 보유하지 않은 것으로 나타났다. 치면열구전색 후 이차우식 발생의 원인은 치면열구전색제가 깨져서 하방에 우식이 생긴 경우가 가장 많았다. 이상의 결과를 종합하면, 치면열구전색 하방의 우식이 전색 후 이차우식 유발에 영향을 미치는 것으로 나타났다. 따라서 치면열구전색 후 이차우식을 예방하기 위해서는 열구 내 우식 정도를 정확하게 진단 평가하는 것이 중요하며, 보다 객관적으로 진단할 수 있는 우식 진단기기의 사용에 대한 교육 및 홍보가 필요할 것으로 생각된다.

The aim of this study was to evaluate the competency of the Easyperio test, a genetic test method based on real time PCR for the detection of bacteria that cause dental caries and periodontal disease. To verify the validity of this text, various dental health evaluations were administered to 33 boys between the ages of 12 to 14, as this age group commonly experiences dental caries. These evaluations included a dental caries experience survey, a first molar health evaluation, the Dentocult Streptococcus mutans (SM) strip mutans, the Dentocult Lactobacillus spp (LB) test, and the Easyperio test. The correlation coefficients between the level of the Dentocult SM strip mutans and the dental caries experience were DT (R=0.570, p=0.001), DMFT (R=0.376, p=0.031), and first molar health (R=-0.395, p=0.023). The correlation coefficients between the amount of SM in the Easyperio test and dental caries experience were DT (R=0.528, p=0.002), DMFT (R=0.369, p=0.035), and first molar health (R=-0.426, p=0.013). The correlation coefficients between the level of the dentocult SM strip mutans and the SM amounts of the Easyperio test were S.mi (R=0.564 p=0.001) and S.mu (R=0.621, p=0.002). The correlation coefficients between the level of the Dentocult LB test and the SM amount of Easyperio test was S.mi (R=0.495, p=0.003). In conclusion, Easyperio test may be an easy and effective method for the differentiation and diagnosis of dental caries through quantitative and qualitative analysis of oral bacteria.

Silver diamine fluoride (SDF) is an alkaline topical solution and it derives from the conjunction of silver nitrate and fluoride. It reduces the growth of cariogenic bacteria, inhibits degradation of dentinal collagen, impedes demineralization and enhances remineralization. It is inexpensive due to the low cost of materials and its application to dental surface is very simple and requires relatively short chair time. Previous studies have shown that the dental caries prevention effect of SDF is superior or similar to topical fluoride application. The main disadvantage of SDF is its esthetic result, and it permanently blacken carious enamel and dentin. The use of SDF has not yet been approved in Korea, but it may be helpful to prevent and treat dental caries in patients with special health care needs and uncooperative young patients.

Objectives： Oral health care program for the elementary school children (ESOHCP) should be met the first priority because dental caries are highly sensitive and prevalent among them. This study was performed to enhance the efficiency of ESOHCP, and their oral health promotion. Methods： The Subjects were 346 students (3rd grade 163, 6th grade 185) of one elementary school in Busan. Dental IQ and actual oral health status； the decayed, mixing and filling teeth were checked through questionnaire and oral health examination from April to June 2002. Dental IQ was presented out of one hundred, and data analysis was done using SAS (ver 8.1) program. Results： The students' cognitive level about the causative and preventive factor of dental caries was relatively high. However, the practical aspects of preventive behavior - tooth brushing； three times per day (20％), three minutes per time (22％), oral health examination； one time per three months (10％) left much to be desired. And, only 27％ of the subjects had experienced in school oral health education. The mean level of dental IQ was 79 out of 100, and 51 ％ and 42％ of them had the decayed and teeth with filling, respectively, with the rate of DMFT 82％, DT 43％, FT 57％. The level of dental IQ was higher in case of having his (her) own tooth brush (p＝0.072), standard tooth brushing (p<0.001) three times per day, post meal, three minutes per time, present experience of oral health examination (p<0.001) and dental clinic visit (p<0.001). The grade of caries was more serious in case of 6th grade (p＝0.059), an absence of his (her) own tooth brush (p＝ 0.090), present experience of oral health examination (p＝0.021), and an absence of regular dental clinic visit (p＝0.003). The frequency of oral health examination (γ＝ 0.620), tooth brushing； times per day (γ＝0.445), post meal (γ＝0.355), expending times per brushing (γ＝0.352), right cognition to the treatment of caries (γ＝0.401), positive attitude to dental treatment (γ＝0.387), the frequency of dental clinic visit for the past one year (γ＝0.152) showed significant correlation with dental IQ. In the multivariate analysis, dental IQ was influenced by the frequency of oral health examination, right cognition to the cause of caries, times of teeth brushing per day, right cognition to the treatment of caries, etc., with adjusted R2＝0.857. Conclusion： Though the students' cognitive level about the causative and preventive factor of dental caries was high, the practical aspects of preventive behavior left much to be desired. Ant the current ESOHCP considered to be still inefficient. However, frequent dental visits had apparent correlation with hish level of dental IQ. The specialized and practical program should be needed for the efficient ESOHCP. Harmonized effort from educational, health and dental society is essential.

The purpose of this study was to do an epidemiological survey of the salivary reductase activity and dental caries prevalence of the large group of preschool children and analyze the validity of the salivary reductase activity test as a caries activity test. One thousand and forty-four preschool children were examined for caries experience and salivary reductase activity by dental survey and the Resazurin Disc Test. 39.8% of children showed low salivary reductase activity, 39.4% showed middle, and 20.8% showed high. Salivary reductase activity increased as age increased. All indexes of caries experience were high when salivary reductase activity was high. There was positive relation between salivary reductase activity and caries experience. The salivary reductase activity of children with no caries experience was lower than that of children with caries experience. The salivary reductase activity of children with low caries experience was lower than that of children with high caries experience. It seemed that the salivary reductase activity test had basic validity as a caries activity test. However, the test's ability to select the small risk group of high caries susceptibility should be enhanced.

The aim of the present study was to investigate the dental caries experience in disabled people according to the handicapped types in Korea. This study subjects based on the national disabled survey 2004 were collected by designed cluster sampling and interviewed with structured questionnaire in order to examine dental caries and sociodemographic status. The subjects were attending the special schools and private or public welfare institutions for crippled disorder, encephalopathy disorder, mental retardation, visual disturbance, and hearing defect. Oral examination was conducted by 13 trained dentists. 1,307 of handicapped people were finally analysed. ANOVA and Cochran-Mantel-Hanzel analysis were adapted for statistical analysis. The results were as follows; Dental caries prevalence, DMFT(Decayed, missing, filled teeth), and DMFS(Decayed, missing, filled surfaces) of disabled people were higher in crippled disorder and mental retardation than the others. There were significant differences in dental caries prevalence, DMFT, and DMFS according to the disabled. DMFT was significantly higher than national population in every age group except in 12-14 year-old and more than 35 group. It was likely that the experience level of dental caries was significantly different according to the handicapped types in Korea and higher than the people without handicap.
