Objectives : In most developed countries there has been a substantial decrease in the prevalence of dental caries in children of 12 years old over the past 40 years. This change in epidemiology highlights the importance of preventive management in dentistry. For successful management of early caries lesions, it is essential to detect and assess the pathological changes of dental caries. Therefore, the purpose of this study was to investigate the overview of International Caries Detection and Assessment System(ICDAS) criteria for the detection and assessment of early caries lesions by literature reviews. Methods : The author reviewed the MEDLINE search by the key words of 'caries assessment', 'caries detection', 'caries measurement', and 'ICDAS'. Results : This literature review provided an overview of International Caries Detection and Assessment System(ICDAS) criteria for the detection and assessment of early caries lesions. This article showed the principles, concept, and primary caries detection criteria of the ICDAS. The ICDAS can macroscopically measure the enamel surface changes and potential histological depth of caries lesions by the surface characteristics of the teeth. The ICDAS criteria allow researchers and clinicians to choose the stage of dental caries and characteristics for assessment. Conclusions : ICDAS can be an adjunct method to clinical decision making and preventive treatment planning.

Dental Caries which has high prevalence rate, accounts for majority of dental diseases. Many treatment and preventive treatment has been developed, thereby reducing the prevalence rate, but in our country, fluoridization has not spread widely yet, so prevention has not been done satisfactorily. When dental caries progresses, irreversible damage of tooth structure occurs. In initial dental caries, demineralizing tooth structure can be remineralized, so restorative treatment is unnecessary. In this study, 20 teeth restored with composite resin without fluoride release were used and divided into two groups. Incipient dental caries were artificially made and demineralization procedure was done for 1 and 2 weeks, for each group. Changes in mineral contents around the margins were analysed with confocal laser scanning microscope. The results were as follow. 1. Both total fluorescence of the lesion and average fluorescence of the lesion of remineralized samples decreased compared to demineralizing state. (p＜0.01) 2. Confocal laser scanning microscopy can be used in quantitative analysis of mineral change. In result, confocal laser scanning microscopy can be used in quantitative analysis of mineral change and it could be used in many different fields of dentistry in the future.

Objectives : The purpose of this research is to use data from the third year of the 4th National Health and Nutrition Examination Survey to study relationship between oral disease and chronic disease that generally persist from 6 months to over a year, or more specifically, circulatory disease, diabetes, and osteoporosis. Methods : Of the data from the third year of the 4th National Health and Nutrition Examination Survey, 7,893 adults over 19 years old who completed medical examination, health survey, and nutrition survey were selected as the final research subjects. Relationship between chronic disease and oral disease was analyzed by cross tabulation (2-test) and logistic regression analysis using SPSSWIN ver 18.0. Results : 1. Differences in the rate of prevalence of periodontal disease and the rate of prevalence of missing teeth were statistically significant with respect to age, gender, marital status, education level, residential area, income level, and occupation. Rate of prevalence of dental caries was statistically significant with respect to age, education level, and income level. 2. After examining the relationship between existence of chronic disease as diagnosed by doctor with oral disease, rate of prevalence of periodontal disease and missing teeth, hypertension, hyperlipidemia, stroke, myocardial infarction, angina, diabetes, and osteoporosis showed statiscally significant difference. 3. Examination of rate of prevalence of chronic disease with respect to oral disease, periodontal disease and missing teeth exerted statistically significant influence on hypertension, hyperlipidemia, stroke, myocardial infarction, angina, diabetes, and osteoporosis (p<0.05), while dental caries did not have statistically significant effect. 4. Analysis of coupling effect of periodontal disease and missing teeth on chronic disease showed that they were related in all chronic diseases examined in this study (hypertension, hyperlipidemia, stroke, myocardial infarction, angina, diabetes, and osteoporosis) (p<0.05). Conclusions : Periodontal disease and missing teeth were found to increase the rate of prevalence of chronic disease.

이 연구의 목적은 건강보험심사평가원의 자료를 이용하여 만 14세 이하 소아청소년들의 치아 우식 유병률의 경향성과 치료의 현황을 파악하는 것이다. 이 연구는 2011년부터 2020년까지 연도별로 전체 소아청소년이 포함된 모집단에서 약 100만명을 무작위 표본 추출한 집단의 진료내역을 이용하여 분석을 시행하였다. 이 연구에서 K02 치아우식 주상병명을 진단받는 아이들은 연도별로 증가하였고, 전반적으로 모든 연령군에서 치아 우식 치료를 받는 아이들도 증가하는 경향성을 보였다. 반면 중증의 치아 우식으로 인해 치수 치료 또는 발치를 경험한 10 - 14세 어린이들은 감소하는 경향을 보였다. 2021 - 2022년 아동 구강 건강 실태조사에서도 5세와 12세의 우식경험지수는 정체되거나 소폭 증가하는 경향을 보였으나 우식 유병자율은 감소하였다. 치료적 관점에서 개인적, 지역적 환경은 과거에 비해 전반적으로 개선된 것으로 나타났으나 예방적 관점에서 치아 우식 유병 상태와 예방 진료가 지난 10년간 개선되지 않고 정체 상태로 머물러 있던 것으로 해석된다. 따라서 대한민국에서 소아청소년을 대상으로 구강건강 증진 및 예방을 위해 시행되고 있는 구강 보건 사업에 대한 홍보와 효용성에 대한 평가가 필요하다.

Objectives : The purpose of the study is to investigate the risk factors of dental caries in early childhood. Methods : Subjects were 197 mothers having 5 year old children. They completed the questionnaire from June 1 to July 14, 2012. Results : At birth, the age of mother and the number of teeth experiencing dental caries showed high correlation(r=0.163, p<0.05). Early beginning(r=-0.441, p<0.05) and long period(r=0.441, p<0.05) of mix feeding were closely related to dental caries outbreak. Long period of supplementary food caused deciduous dental caries (r=0.643, p<0.001) and dental caries experience (r=0.723, p<0.001). Long period of breast feeding (r=0.261, p<0.001) also caused deciduous dental caries. Low BMI of mother was colsely related to high dental caries(r=-0.206, p<0.01). Deciduous dental caries accounted for 61.8% and the number of teeth experiencing dental caries was 68.5%. Conclusions : Appropriate breast feeding habit is the most important behavior of preventing deciduous dental caries in 5 year old children.

Objectives: The aim of this study was to investigate the factors related to dental caries and periodontal disease in Korean adults. Methods: The subjects were 5,149 adults over 19 years old who participated in the 5th Korea National Health and Nutrition Examination Survey 2012. Data were analyzed by chi-square test and logistic regression analysis using SPSS 18.0 statistical package program. The questionnaire consisted of 17 questions of independent variables and 2 kinds of dependent variables including dental caries and periodontal diseases by direct interview. The independent variables included 5 questions of general characteristics, 3 questions of health behavior, 5 questions of oral health behavior, and 4 questions of chronic diseases diagnosed by the doctors. Results: The prevalence rate of dental caries was higher in those who did not regularly work out and did not receive regular checkups including dental floss and dental brush use. The prevalence rate of periodontal diseases was higher in male adults, smokers, and those who were obese and had diabetes mellitus, poor oral health care habit without using dental floss and inter-dental brush. Conclusions: In order to prevent the dental caries in the adults, it is very important to do regular exercise and regular dental checkup. The best ways of dental caries prevention include tooth brushing after meal with use of dental floss and inter-dental brush. This study suggests that dental health promotion can be enhanced by smoking cessation, ideal body weight maintenance, timely tooth brushing after meal, and use of dental floss and inter-dental brush.

Objectives: The study aimed to isolate the abundant bacteria in dental caries in children and to investigate the bacterial species involved in addition to those that have been previously reported. Methods: The specimens were collected from the supragingival plaques of each dental caries area, pit and fissure caries, deep dentinal caries, smooth surface caries, and dental caries, and from healthy subjects in the control group. Bacteria were cultured from these specimens, DNA was extracted from the isolated bacteria, and the 16S rRNA gene sequences were analyzed and identified. Results: Based on the results of the 16S rRNA gene sequence analysis for the 90 strains of dominant bacteria from the 45 specimens, 5, 7, 8, 7, and 13 species were identified from the supragingival plaques from healthy teeth, pit and fissure caries, deep dentinal caries, smooth surface caries, and dental caries, respectively. In healthy teeth, Actinomyces naeslundii dominated. Corynebacterium durum, Ralstonia pickettii, and Streptococcus intermedius showed equal distribution. The dominant bacterial species in dental caries, S. sanguinis, showed the greatest difference in prevalence in pit and fissure caries. In deep dentinal caries, S. mutans and Lactobacillus rhamnosus were dominant; in smooth surface caries, S. mutans and S. sanguinis were dominant; and in the supragingival plaques of dental caries, S. sanguinis and S. mutans were dominant. Conclusions: The bacterial species isolated from dental caries encompassed four phyla, eight genera, and 22 species. In addition, the SS1-2 strain, belonging to the genus Neisseria, was identified as a new species from among the isolated strains.
