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.

Purpose : This study aimed to analyze the level of understanding of Korean children and adolescents of caries risk assessment items in order to develop caries risk assessment tools. Methods : A total of 52 parents and 108 middle and high school students were analyzed for their understanding of nine items of the CAMBRA CRA for Korean children and adolescents. The nine questions were analyzed through a Likert five-point scale. Centralized distribution analysis was conducted to compare significant differences in the three groups' understanding of the questions. Results : The evaluation of the middle school and high school students' understanding showed that four items scored less than 3.0 points. The items were "Hyposalivatory medications (antihistamines, antipsychotics, asthma, etc.)," "Brushing below once a day," "F varnish last six months," and ".12 % chlorhexidine gluconate mouthrinse daily seven days monthly." The understanding of elementary school parents of ".12 % chlorhexidine gluconate mouthrinse daily seven days monthly" was less than 3.0 points. In addition, as a result of comparing the averages of the three groups, a statistically significant difference (p<.05) was found for a total of five items: "Hyposalivatory medications (antihistamines, antipsychotics, asthma, etc.)," 'Not used oral products such as floss and interdental toothbrushes," "F toothpaste 2× daily or more," "F varnish last six months," ".12 % chlorhexidine gluconate mouthrinse daily seven days monthly." Conclusion : This study was conducted to provide basic data for the development of a caries prevention program by identifying whether the caries risk assessment reconstituted in Korean style can be used for children and adolescents. More than half of the questions scored 3.0 points or higher and were generally completed. Nonetheless, a systematic program can only be completed if a plan is secured to improve repondents' understanding of the questions before a caries prevention program is developed.

Purpose: The present study confirms the content validity and understanding level of the questions of the Korean version of caries management by risk assessment (CAMBRA). Methods: To develop the Korean version of CAMBRA for children aged 0-5 years, a series of steps were followed: first, translation and reverse-translation processes were conducted by an expert committee. To establish content validity, CAMBRA was modified to adapt to the conditions in Korea by 17 dental hygiene professionals with a master's or a higher degree. The responses were analyzed using analysis of frequency and descriptive statistics. Content validity was verified by calculating the content validity index (CVI). The survey was administered to 64 mothers and caregivers to assess the understanding level of questions of the Korean version of CAMBRA. Results: Content validity of each of the items showed an S-CVI/AVE value of 0.79, but the content validities varied from 0.63 to 1.0. The understanding level of each question was between 3.56 and 4.46, thus showing favorable results. Conclusion: It was concluded that the test items verified for content validity were suitable for assessing caries risk for children of ages 0-5 years. This study would contribute to improving children's oral health and disease prevention by providing timely intervention.

치아 우식증은 어린이와 청소년에서 일생에 거쳐 지속되는 질병이며 가장 중요한 치과질환이다. 유치열기의 치아우식증은 영구치에도 영향을 미치기 때문에 유치의 치아우식증을 조기에 진단하는 것은 매우 중요하다. 또한 예방을 하는 것이 매우 중요한데 치아 우식증을 조기에 발견하여 우식 위험율이 높은 아이들에서 적극적으로 불소 도포, 치면 열구 전색 등을 미리해주는 것이 중요하다. 치아우식증을 조기에 발견하기 위한 방법들이 많이 개발되어 왔지만 더 효율적인 방법을 찾기 위해 여전히 많은 연구가 진행 중이다. 일반적으로 시진과 방사선 사진을 많이 사용해왔지만 시진의 부정확성과 방사선의 조사량 등 많은 한계점을 보이고 있다. 이번 연구에서는 치아 우식증에 있어서 새로 개발된 DIAGNOcam의 임상적 적용에 대해 알아보고 그 활용 가능성을 알아보고자 하였다. 소아치과에 내원한 환자들을 대상으로 구치부에 DIAGNOcam을 이용하여 진단한 결과 인접면 우식, 수복물의 변연 확인 및 우식의 범위 확인에 유용하게 사용될 수 있다는 점을 확인하였다.

Objectives : The purpose of this study was to investigate the relationship between early childhood caries(ECC) and breastfeeding. Methods : Data of 670 children were derived from the Forth Korean National Health and Nutrition Examination Survey from 2007 to 2009. Demographic and socioeconomic data, oral health related behavior, and breastfeeding practice data were collected as independent variables. The ECC was used as a dependent variable. The chi-square test and logistic regression analysis were performed to identify the relationship between ECC and the other variables. Results : Multiple logistic regression analysis revealed that ECC was related with age, tooth brushing frequency, and breastfeeding practice. Conclusions : This study confirmed various risk indicators of ECC in Korean children, using Korean national survey data. Parents should begin an early and consistent mouth care regime to decrease the risk of ECC.

치아우식증은 치아, 바이오필름(biofilm), 식이 요인의 상호작용을 기본으로 타액, 불소 등의 구강 환경요인과 생물학적, 행동적, 사회문화적, 유전적 요인이 관여하는 복잡한 다인성질환이다. 최근 치아우식증은 외부 병원체의 감염에 의한 것이 아닌 구강 미생물군의 생태적 변화에 따른 불균형(dysbiosis)의 결과로 이해되면서 전염성질병에서 비전염성 질병(non-communicable diseases, NCD)으로 전환되었다. 치아우식증은 심혈관질환이나 당뇨병과 같이 만성적으로 진행되는 비전염성 질환(NCD) 특성을 가지며, 식이섭취와 생활 습관과 환경적 요소들이 관여한다는 점에서 유사성이 있다. 높은 유병률과 함께 사람들의 건강과 삶의 질에 미치는 영향을 감안할 때 효과적인 구강 건강관리를 목표로 비전염성질환(NCD)로서 치아우식증에 대한 이해가 필요하며, 구강 미생물군의 생태적 균형을 이루기 위한 적절한 예방법과 효율적인 공중보건 정책들이 제공되어야 할 것이다.

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.
