Dental caries has been widely prevalent with presence of cavitation on teeth. For the last several decades, the prevalence of dental caries in developed countries has rapidly decreased so there has been needed a new and detailed diagnostic guideline to differentiate the severity of dental caries, especially for early status of caries. The cariology specifically requires the development of an integrated definition of dental caries and uniform systems for measuring the caries process in the fields of clinical diagnosis and treatment, epidemiological researches, and dental education and so forth. The international Caries Detection and Assessment System (ICDAS) optically measures the enamel surface changes and potential histological depth of carious lesions by relying on surface characteristics of teeth. ICDAS is a visual classification system that was developed to diagnose the subtle changes of enamel surface, predict the progress direction of early caries, allow standardized data collection in relation to caries in different settings, and to enable better comparison of oral health between countries worldwide and research studies.

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.

The purpose of this study was to examine the influence of maternal socioeconomic status, maternal oral health behaviors, and oral health behaviors of children, on the prevalence of early childhood caries in children aged 5 years. The Korean National Health and Nutrition Examination Survey data collected between 2007 and 2014 were applied to this study, and the study sample included 824 children who received oral examinations and participated in the health behavior survey. The factor that affected the prevalence of early childhood caries were confirmed by maternal and child factors. The data were analyzed using multiple linear regression. The mothers' age, income level, and job status affected the prevalence of early childhood caries. There was a significant difference in the analysis considering the factors of motherhood and children in the prevalence of early childhood caries according to mother's age, education level, income level, and the child's oral examination. The prevalence of early childhood caries was higher in children who received oral examinations than in those who did not. When the mother's educational level was higher than college education, it was found that the index of child, i.e., there was a difference in the prevalence of early childhood caries according to the mother's educational and income levels. These results indicate that maternal socioeconomic characteristics are correlated with the oral health of children. Therefore, oral health education programs that include mothers for the prevention of early dental caries in children may improve the dental health of children. In addition, specific oral health policies are necessary to address the differences in the oral health between the income groups.

Early childhood caries is a widespread condition that requires attention; however, its treatment remains a challenge in terms of child behavior management. This study describes the usefulness of customized zirconia crowns for the restoration of deciduous teeth through the evaluation of some cases. Three cases are described: a 29-month-old girl who presented with severe early childhood caries affecting anterior tooth, a 50-month-old boy who presented with extensive caries of his anterior tooth, and 70-month-old girl who presented with extensive caries of his primary posterior dentition. These prefabricated, zirconium-based ceramic crowns ($Nusmile^{TM}$ NuSmile) are available in various sizes, shapes and colors. Before the treatment, radiographs and intraoral photographs were taken to evaluate the appropriateness of treatment. Our findings indicate that customized zirconia crowns may be appropriate for restoring the deciduous teeth. Further long-term clinical studies are required to clarify the usefulness of this restorative method.

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 effect of breastfeeding on the occurrence of early childhood caries in Korean infants and toddlers. Methods: Data on oral examinations of infants and toddlers of the National Health Insurance Service were analyzed. The study subjects were children who participated in both the first, second, and third oral examinations and the first general health examination in 2008-2017 (n=142,185). Based on the responses to the questionnaire, the subjects were classified into breastfeeding, formula feeding, and mixed feeding groups. The participants were monitored for the development of early childhood caries in three sequential oral examinations. Results: Based on the oral examination results conducted at 54-65 months old, the decayed-filled teeth index of the breastfeeding group was the highest (2.03±3.08), followed by the mixed (1.96±3.03) and the formula feeding groups (1.82±2.91). The Cox proportional hazard regression model including all the variables showed that the risk of developing dental caries was significantly lower in the formula (hazard ratio [HR], 0.85) and mixed feeding groups (HR, 0.91) than in the breastfeeding group. Conclusions: Breastfeeding children have a higher risk of early childhood caries; therefore, oral hygiene education and regular dental check-ups are necessary.

영유아기 치아우식증은 복잡하고 다인자적 질환으로 숙주 및 미생물, 식이, 시간 등의 위험요소에 의해 질환이 진행된다. 이 중 미생물로 대변되는 Streptococcus mutans(S. mutans)는 우식 개시에 있어 중요한 역할을 하며, 어머니를 통한 수직 감염이 잘 알려져 있다. 영유아기의 어머니를 통한 조기 감염은 향후 유치열기 우식 발생과 높은 연관성을 나타내므로 우식위험요소에 대한 조기 파악은 미래의 치아우식증 예방에 있어 매우 중요하다. 최근 치아우식증의 원인 및 이에 미치는 요소들에 대한 연구가 활발하게 이루어지면서 우식 진행에 대한 정확한 예측을 위한 여러 가지 우식위험도평가(caries risk assessment) 도구가 개발되었는데, 이 중 대표적인 한 가지가 Cariogram이다. Cariogram은 개인의 우식활성도 및 우식위험요소(caries risk factor)의 상호작용을 그래프로 나타낸다. 이번 연구의 목적은 3${\sim}$5세의 중증 유아기우식증(Severe Early Childhood Caries; S-ECC)에 해당되는 어린이들과 그들의 어머니 사이에서 우식관련타액검사 및 최근 개발된 Cariogram을 이용하여 S. mutans의 수준 및 우식활성도에 대한 상관관계가 존재함과 우식위험요소 간의 연관성을 파악해 보았는데, 이를 통해 다음과 같은 결론을 얻을 수 있었다. 1. 중증 유아기우식증을 보이는 어린이에서 구강 내 존재하는 Streptococcus mutans의 수준은 비우식군보다 높았다(p<0.05). 2. 모자간 구강 내 존재하는 Streptococcus mutans 수준은 상관관계를 보였다(p<0.05). 3. 모자간 우식활성도를 Cariogram을 통해 측정해 본 결과 상관관계를 보였다(p<0.05). 4. 우식활성도에 미치는 우식위험요소는 어린이에서 숙주요소가 가장 큰 영향을 주는 것으로 나타났다. 이상의 결과로 S. mutans가 향후 치아우식증 발생 가능성을 예측하는데 있어 유용한 우식위험요소가 될 수 있으며, Cariogram을 통한 향후의 우식진행과 관련된 여러 가지 우식위험요소가 예측 가능하므로 이에 대한 조기 대처 및 예방적 처치가 가능하리라 사료된다.

Objectives: The purpose of the study is to investigate remineralization effect according to application cycle of fluoride varnish in preschool children. Methods: The study subjects were fifty six children (92 teeth) having one or more early dental caries lesion. Fluoride varnish was applied to the primary area of maxillary and anterior mandibular teeth with the interval of one month, three months, and six months. Results: Dft index was 3.54 in male and 3.44 in female. The fluorescence loss(${\Delta}F$) value due to early caries lesions showed a significant difference in experiment groups I and II after the application of fluoride varnish, but there was no significant difference in experiment group III. After fluoride varnish application, there was a significant change in experimental group I and III. The maximum fluorescence loss(${\Delta}Fmax$) from early caries lesions showed a significant difference after application of the fluoride varnish in all three experiment groups of I, II, and III(p<0.001). Conclusions: Fluoride varnish should be recommended and applied to the children of high risk caries group in every three months.
