Objectives: The water fluoridation program has been implemented since 2008, in a region of Geoje City. This study aimed to evaluate the effectiveness of the water fluoridation program on caries prevention in the permanent dentition. Methods: Evaluation surveys were conducted on 8-, 10- and 12-year-old children in the fluoridated and non-fluoridated regions of Geoje City, in 2015. The survey included 834 children from the fluoridated regions and 703 from the non-fluoridated regions. The data obtained from the survey were analyzed using the IBM SPSS statistical package version 23.0. The effectiveness of community water fluoridation in caries prevention was estimated by the differences in the decayed, missing, filled teeth (DMFT) and decayed, missing, filled surfaces (DMFS) scores, between the program and control groups. The mean numbers of fissure-sealed teeth and surfaces were adjusted to reduce their confounding effect. Results: The mean DMFT and DMFS scores (0.69 and 0.91, respectively) of 10-year-olds from the fluoridated regions, after adjusting for the numbers of fissure-sealed teeth and surfaces, were significantly lower than those of the 10 year olds (DMFT: 0.95, DMFS: 1.32) from the non-fluoridated regions. The effectiveness of water fluoridation on caries prevention in the permanent dentition, estimated based on the differences in the mean DMFT and DMFS scores, adjusted for the number of fissure-sealed teeth and surfaces, between the program and control groups of 10-year-old children, was 27.4% and 31.1%, respectively. Conclusions: These results suggest that the effectiveness of water fluoridation on caries prevention in the permanent dentition, in Geoje City was so high that this program should be implemented in other regions in Korea as well.

Background: The purpose of this systematic review was to investigate the effects of topical fluoride gel application on dental caries prevention in the permanent teeth of children and adolescents. Methods: We searched the EMBASE, PubMed, and Cochrane Library databases for randomized controlled trials (RCTs) assessing the effects of self-applied or professionally applied topical fluoride gels in patients <18 years of age; the search was completed on April 1, 2018. All included trials involved an experimental group (fluoride gel application) and a control group (placebo or no treatment). The outcome measures were the D(M)FS and D(M)FT indices, which were compared between the two groups. Review Manager software was used for quantitative synthesis of the final selected articles, and a forest plot was generated via a meta-analysis conducted using a random effects model. Results: The results showed that the D(M)FS and D(M)FT indices were lower in the fluoride application group than in the control group, thus indicating that fluoride gel application was effective in dental caries prevention. We also performed a subgroup analysis to determine whether the effects of fluoride application differed if patients received oral prophylaxis (self or professional) before fluoride gel application. Therefore, the two groups showed slightly larger differences when studies without oral prophylaxis before fluoride gel application were considered; however, the difference was not statistically significant. Conclusion: These findings should be utilized to raise awareness about the caries-prevention effects of topical fluoride application among patients and guardians. Further RCTs should evaluate the effects of fluoride application with or without preceding oral prophylaxis, and appropriate fluoride application guidelines should be developed to maximize the effects of fluoride application in clinical practice.

This study was performed to evaluate the importance of parents, knowledge, cognition and behaviour about dental health care on the development of dental caries in preschoolers. Subjects were comprised of 170 preschoolers collected from three preschoolers placed in Pusan and Kimhae area and study period were 6 months from January, 2000. Examination on the preschoolers' dental health and questionnarie survey on parents' knowledge, cognition and behaviour about dental health care were conducted. Collected data were analyzed by chi-square test and t-test using SAS program. Dental caries was so prevalent as the rate of 73.5%. And, the rate was different by the area(p=0.001), and increased with preschooler's age(P=0.004). The parents gain the knowledge about dental health care mainly from dentist or dental hygienist(32.9%), newspaper, magazine booklets(26.5%), TV and VTR tape(20.0%), etc, but rarely from school health education(4.7%). Caries prevalence was significantly lower in case of regular brushing than that of insufficient brushing(p=0.002) and in case of consistently informing brushing time to their children(p=0.014). This results showed that the dental health care for preschoolers is insufficient and the most important factor for caries prevention is regular brushing. And it seemed that the parent's concern and knowledge play an important role for the prevention of preschooler's dental caries. Dental health education would be focused on the parents, especially for the practice of preventive behavior by preschoolers themselves.

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.

Objectives : The purpose of this study was to survey Korean solders' oral healthcare recognition and perceived oral health concern. Methods : The data was collected from a questionnaire given 157 soldiers in Chungcheongnamdo. The data was analyzed into t-test, one-way ANOVA and Pearson's correlation analysis. Results : 25.5% replied that they were concerned about oral health. Soldiers who have received oral healthcare education exhibited higher recognition on the prevention of dental caries and periodontal disease. Moreover, those who have used oral hygiene devices also showed higher recognition on the prevention of dental caries and periodontal disease. The recognition of preventive effects on dental caries, in particular, showed a statistically significant difference (p<0.05). In regard to the relationship between oral health concern and recognition of oral healthcare, those who were more concerned about oral health were higher recognition of periodontal disease prevention(r=0.254, p<0.01). Conclusions : To improve concern and recognition of oral health for the members, the soldiers needs to develop oral health education and policy.

Purpose: The aim of this study was to analyse and review deep learning convolutional neural networks for detecting and diagnosing early-stage dental caries on periapical radiographs. Materials and Methods: In order to conduct this review, the Preferred Reporting Items for Systematic Reviews and Meta-Analyses(PRISMA) guidelines were followed. Studies published from 2015 to 2021 under the keywords(deep convolutional neural network) AND (caries), (deep learning caries) AND (convolutional neural network) AND (caries) were systematically reviewed. Results: When dental caries is improperly diagnosed, the lesion may eventually invade the enamel, dentin, and pulp tissue, leading to loss of tooth function. Rapid and precise detection and diagnosis are vital for implementing appropriate prevention and treatment of dental caries. Radiography and intraoral images are considered to play a vital role in detecting dental caries; nevertheless, studies have shown that 20% of suspicious areas are mistakenly diagnosed as dental caries using this technique; hence, diagnosis via radiography alone without an objective assessment is inaccurate. Identifying caries with a deep convolutional neural network-based detector enables the operator to distinguish changes in the location and morphological features of dental caries lesions. Deep learning algorithms have broader and more profound layers and are continually being developed, remarkably enhancing their precision in detecting and segmenting objects. Conclusion: Clinical applications of deep learning convolutional neural networks in the dental field have shown significant accuracy in detecting and diagnosing dental caries, and these models hold promise in supporting dental practitioners to improve patient outcomes.

현재까지, 식이 당의 전체적 또는 부분적 대체당으로서 자일리톨의 치아우식증에 대한 예방 효과를 확인하기 위해 많은 연구가 수행되었다. 본 총설논문에서는 자일리톨의 구강건강에 대한 기존 연구들을 바탕으로 자일리톨의 치아우식증 예방 기전, 치아우식증 예방, 치아우식증 유발균의 모자전염 예방, 노인의 구강건강에 미치는 영향 등이 정리되었다. 식품에 함유된 탄수화물 및 식이 당은 구강 내에서 산을 생성하는 미생물에 의해 발효되어 치석 및 산을 생성하여 치아우식증을 일으킨다. 그러나 충치를 일으키는 세균 대부분은 자일리톨을 대사하여 산을 만들어 낼 수 없다. Streptococcus mutans (S. mutans)에 의한 비대사성 대사물로서 세포 내에 축적된 자일리톨은 S. mutans의 성장을 억제하고 치석 형성을 억제하여 치석과 타액 중 S. mutans 수를 감소시킨다. 또한, 자일리톨은 치아의 재광화(remineralization) 과정에 작용한다. 자일리톨은 치아우식증 예방, S. mutans의 모자감염 예방, 노인의 충치예방 및 타액분비 증가에 효과가 있는 것으로 확인되었다. 결론적으로, 자일리톨은 남녀노소 구분 없이 구강건강에 효과적이며 쉽게 섭취할 수 있는 장점이 있다. 향후, 자일리톨의 과량섭취에 따른 부작용과 구강 및 장내 환경에 미치는 전반적인 영향에 대한 보다 정확하고 상세한검토가 필요하다.

최근 치아우식증이 예방가능한 질환이라는 사실이 부각되면서 치료에 대한 개념이 다소 변화하게 되었다. 즉, 단순한 수복 치료가 아닌 '예방적 우식 조절(preventive caries control)'을 통한 관리가 필요하다는 것이다. 이러한 치아우식증에 대한 철학의 변화는 구강 검사의 방법이나 기준의 변화를 수반하였는데, 이미 형성된 우식 와동을 관찰하는데 그치는 것이 아니라, 와동형성이 이루어지기 전의 초기 단계에 해당하는 우식 병소를 정확하게 탐지하는 것이 필요하게 된 것이다. 최근 개발된 International Caries Detection and Assessment System II (ICDAS II)은 시진을 기반으로 한 치아우식증의 분류 기준이다. 이 분류 기준은 치아우식증의 예방 및 조기 진단과 환자 중심의 우식 관리를 지향하는 최근 경향을 바탕으로 하고 있는데, 이는 어린이의 양호한 구강 건강을 조기에 확립하여 이를 평생 유지할 수 있도록 돕는 것을 목표로 하는 소아치과학의 관점과 잘 부합한다고 볼 수 있다. 이에 저자는 어린이의 구강 검사에 ICDAS II를 적용하기 위한 기초를 제공하기 위해 이 분류 기준을 소개하고자 한다.
