This study aims to identify the regional distribution in the prevalence of dental caries and related multidimensional factors among 12-year-old children in Korea. Data from the 2018 Child Oral Health Survey were used to calculate the average DMFT index of 12-year-old children in metropolitan cities, and a multi-level regression model was applied to explain the regional distribution of dental caries prevalence and related factors. Factors were divided into two levels by administrative structure. This study finds a significant regional difference in the prevalence of dental caries in 12-year-old Korean children across metropolitan cities. Multilevel analysis showed that district-level factors (average number of pit and fissure-sealed permanent teeth, dental treatment demand rate, preventive treatment rate, sex ratio, and number of dentists per 100,000 people) and metropolitan-level factors (intakes of cariogenic beverages and number of pediatric dental hospitals and clinics per 100,000 people) had a significant effect on dental caries prevalence (p < 0.05). Individual characteristics and local socio-environmental factors influence the prevalence of dental caries. Especially considering the strong dependence on preventive treatment and accessibility to dental care services, it is necessary to provide adequate preventive treatment and expand health care resources in high-risk areas of dental caries.

The purpose of this study was to examine the characteristics of the high caries risk group of 12-year-old children in Korea. Oral health status and interview data were collected from 23,089 children aged 12 years who participated in the 2015 Korean Children's Oral Health Survey. Subjects were classified into high-risk and low-risk groups according to the Significant caries (SiC) index, and the influence of each variable was analyzed. As a result of the study, the SiC index of the high-risk group was 5.08, which was about 9.6 times higher than the low-risk group. The risk factors associated with the high-risk group were in the order of the number of sealant teeth, dental treatment demand for the past year, perceived oral health status, gender, region, frequency of snack intake per day, and use of oral hygiene aids. In order to improve the oral health of children, appropriate preventive treatment and oral health education should be carried out with reference to the items indicated as risk factors in the high-risk group of dental caries.
Objectives : This study aimed to explore the influence of food intake and oral health behaviors on dental caries in juveniles. Methods : A total of 2,129 juveniles completed a questionnaire survey to identify the presence of permanent teeth caries, behaviors relevant to oral health and food intake based on the fourth National Health and Nutrition Survey. Results : Multiple logistic regression analysis showed that higher occasions of intake of carbonated drinks significantly cased dental caries in the meanwhile oral health behavior and the number of toothbrushing was in reverse proportion to dntal caries. The risk of dental caries was higher in the group of lower frequency of toothbrushing and intake of carbonated drink. Conclusions : Carbonated drinks intake and the number of toothbrushing is closely related to dental caries. So it is very important to develop oral health education program in order to improve eating habits and toothbrushing habits in juveniles.

The purpose of this study was to evaluate the role of socioeconomic factors and health behaviors on the prevalence of oral diseases(dental caries and periodontal disease) among Korean adults. Data from the 2005 National Health and Nutrition Examination Survey was analyzed for adults aged over 19 years (n=25,215). Oral disease was defined as disease diagnosed by a dentist for the previous 12 months. Chi-square test and logistic regression analysis were used to conduct statistical analysis. The population without dental caries and periodontal diseases were used as the reference category for all analysis. The overall prevalence of annual dentist-diagnosed dental caries and periodontal diseases were 23.5% and 10.6% respectively. The relative risk of developing dental caries for graduates of middle school and lower were 1.53 times (95% CI: 1.24-1.89) more likely to develop dental caries comparing to college graduates. Low income earners were 1.23 times(95% CI: 1.01-1.49) more likely to develop dental caries than high income earners. Persons covered by national medical insurance were 1.45 times(95% CI: 1.08-1.95) more likely to develop dental caries comparing to persons covered by employee medical insurance. Compared with persons not eating snacks, the risk of developing caries in persons eating snacks once a day was 1.16(95% CI: 1.01-1.32), while those who snacked twice or more a day were 1.19(95% CI: 1.01-1.41). The relative risk of developing periodontal disease was 3.71(95% CI: 2.38-5.80) higher in older individuals than younger. In terms of education level, middle school graduates and lower were 1.54 times more likely to develop periodontal disease than college graduates. Low income earners were 1.47 times more likely to develop periodontal diseases than high income earners. Using data from a large, nationally representative sample of Korean populations, we support the hypothesis that the prevalence of oral diseases is related with socioeconomic factors and health behaviors. More intensive intervention efforts to reduce the prevalence of dental diseases are warranted in Korea.
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.
Background: Obesity and dental caries have common risk factors such as food intake, eating habits, and lifestyle. Nevertheless, there has been no consensus on the significant association between obesity and dental caries, and additional studies are needed. We investigated the relationship between obesity and dental caries in some college students in this pilot study. Methods: Forty-two obese college students (body mass index [BMI]≥25) registered at a University Obesity Clinic and 19 normal students (18.5≤BMI<25) were recruited. Oral examinations were conducted, and anthropometric data and blood samples were collected. The blood concentrations of low-density lipoprotein (LDL), high-density lipoprotein, and triglyceride were also measured. After controlling for dental plaque index, a univariate analysis of dental caries indicators related to obesity was performed; partial correlation analysis was also conducted. A nonparametric test was used for the analysis of gender-related trends due to the limited number of participants. Results: The obese group had significantly fewer missing teeth (p=0.014), missing surfaces (p=0.035), filled surfaces (p=0.038), and decayed-missing-filled surfaces (p=0.020) than the normal group. There was no difference between the males in the normal and obese groups. The females in the obese group had significantly fewer missing teeth (p=0.003), missing surfaces (p=0.003), and decayed-missing-filled surfaces (p=0.046). Partial correlation analysis showed a weak negative correlation (r=-0.256) between the blood LDL concentration and decayed-missing-filled teeth. The other obesity and dental caries indicators were not correlated. Conclusion:The blood cholesterol concentration had a negative relationship with dental caries, and there were fewer cases of dental caries in the obese group in this study. However, it is important to clarify the relationship between obesity and dental caries through a dietary survey or additional investigations considering other confounding factors.
In this study, the characteristics and oral health status of manufacturing workers were investigated to confirm the factors affecting their risk of developing dental caries and to prepare basic data for developing oral health promotion programs for such workers. A self-administered questionnaire survey and saliva microorganism examinations (S. mutans and Lactobacillus tests) were conducted from July 1 to August 1, 2014 targeting the manufacturing workers in the Busan and Gyungnam areas, to confirm the factors affecting dental caries development among manufacturing workers. As a result, the risk of dental caries was found to be higher in the workers who worked for 10 hours or longer a day than in those who worked for less than 10 hours a day, and in the smokers than in the non-smokers. A 1-point increase in the brushing pattern score resulted in 0.044 times less risk of dental caries development in the S. mutans test and 0.004 times less risk in the Lactobacillus test Therefore, systematic support is needed to improve the work environment of manufacturing workers, along with continuous oral health education in workplaces.
Objectives: The present study aimed to evaluate the usability, quality, and usefulness of the mobile application, CAMBRA-kids, for caries management in preschoolers. Methods: Ninety-one caregivers and preschoolers participated in the user evaluation of CAMBRA-kids. The evaluators assessed the usability, quality, and usefulness of CAMBRA-kids. The collected data were analyzed using R studio 1.2.1335 for Windows (RStudio Inc. 2018, Boston, MA, USA). The evaluations for usability, quality, and usefulness were analyzed with descriptive statistics, Kruskal-Wallis rank sum test, and Wilcoxon rank sum test. Results: On user evaluation, the quality and usefulness of the application scored >3 points, and majority of the users rated the quality and usefulness of the application as high. The quality of the application's system was the highest at 3.68 points, and the actual usage of the application was the lowest at 3.10 points. The application had the highest technological aspect score of 3.20, whereas the content related to oral health information had the lowest score of 3.10/5. Although the application showed no statistically significant differences in the quality and usefulness according to general characteristics, there was a statistically significant difference (p<0.05) between the two when compared between the caries risk group. For all items, the protector of the high-risk group evaluated the quality and usefulness of the application highly. The moderate risk group gave the lowest evaluation score for the application's quality and usefulness. The usability score of the application, according to the user version of the mobile application rating scale (uMARS), was 3.25, and the average engagement score was 2.82 (56.31%). The highest subscale score was 3.63. Conclusions: In this study, we found suitable quality, usability, and usefulness of the mobile application, CAMBRA-kids. In future, the use of this application will contribute to the prevention of dental caries among preschoolers.
Objectives: This study aims to evaluate carbonated drinks induced dental caries with qualitative analysis and to compare with oral organic acids including lactate, acetate, propionate, formate, butyrate, pyruvate and valerate which cause caries when taking either 10% sucrose drinks or carbonated drinks. Methods: Saliva was collected from six study subjects before and after (start, 5, 10, 30 minutes) taking water intake upon (A) 10% sucrose intake, (B) 10% sucrose intake, and (C) carbonated drink intake, then they were centrifuged at 1,200 rpm followed by removing bacteria and enzymes with syringe filtering, performing a qualitative analysis with HPLC conductivity detection (GP50 gradient pump, ED 50 detector) after saliva pre-treatment under isocratic 100 mM NaOH mobile phase. Results: Higher risk of dental caries was evaluated in order of C>B>A, with the results of total oral organic acids' concentration, lactates of organic acids and organic acids produced after 5 minutes from the 3 types of drinks intake. Conclusions: Carbonated beverages were estimated to develop higher dental caries induction than beverages containing 10% sucrose because of the high organic acid concentration in the mouth after its intake.

Purpose: The aim of this study was to confirm the validity of the $Cariview^{TM}$, test in adults by assessing correlations between $Cariview^{TM}$, scores and caries experience using a quantitative light-induced fluorescence (QLF) technique. Methods: This retrospective cross-sectional study included 111 patients aged 19-64 years who visited a dental clinic in Seoul from 2015 to 2016, and underwent the $Cariview^{TM}$, test and had their teeth photographed with the Qraycam. Plaque was scraped with sterilized cotton swabs, and then placed in a culture medium and incubated at $37^{\circ}C$ for 48 h. Finally, the degree of color change was evaluated, and scored on a 0-100 point scale. Caries experience index included not only cavitated lesions but also early caries that were detected on white and fluorescence images. Participants were divided into low, moderate and high caries risk groups according to the $Cariview^{TM}$, score, and caries experience was compared between risk groups using ANCOVA. Spearman correlation coefficients were calculated to analyze the associations between $Cariview^{TM}$, scores and caries indices. Result: The mean age of the participants was 40 years, and the mean $Cariview^{TM}$, score was $53.6{\pm}20.7$. The WDMFT and the DMFT indices significantly increased with caries risk, and this increase was significantly different between the low- and high-risk groups. The $Cariview^{TM}$, test scores were significantly correlated with the WDMFT (r = 0.28, P = 0.003) and DMFT (r = 0.29, P = 0.002) indices. Conclusion: The $Cariview^{TM}$, test could be a clinically useful and simple method for assessing caries risk in adults.
