OBJECTIVES: The purpose of this study was to evaluate the caries prediction validity and between-observer reliability of caries activity tests using sulfisomidine-containing acidic high sucrose liquid medium (SAHS test). METHODS: This longitudinal follow-up study was done for 1 year. The subjects were 188 elementary school children. The caries experience and caries activity of each of the subjects was examined. We adopted both the SAHS test and Dentocult SM test as caries activity tests. We conducted an ROC analysis on the test data, and thereafter calculated the sensitivity, specificity, predictive value, and Kappa statistics. RESULTS: According to the ROC analysis, it was found that both the SAHS test and Dentocult SM test showed a similar level of AUC (0.5 or higher), which means that both tests have significant caries prediction validity. When the validating criterion was based on 1 or more new caries lesions and the screening criterion was based on a score of 5, it was found that the SAHS test (12 grade) showed a sensitivity value of 0.72-0.73, specificity value of 0.48-0.51, positive predictive value of 0.62-0.63, and negative predictive value of 0.61-0.62, respectively. Based on these 4 values, it was found that the SAHS test had a higher grade of sensitivity and negative predictive value than the Dentocult SM test. However, the latter had a higher grade of specificity and positive predictive value. Despite this, there were no significant differences between both tests. The SAHS test had higher between-observer reliability (kappa value) than the Dentocult SM test (0.90>0.88). CONCLUSIONS: In this study, it was found that both the SAHS test and Dentocult SM test had a similar level of caries prediction validity and between-observer reliability.

OBJECTIVES: The purpose of this study was to compare the amount and rate of cumulative fluoride released over a period of 4 h from several varnishes marketed in Korea. METHODS: The following six commercial products were studied: cavity shield (CS, 22,600 ppm F), V varnish (VV, 22,600 ppm F), enamel pro varnish (EP, 22,600 ppm F), MI varnish (MI, 22600 ppm F), fluorine care (FC, 22600 ppm F), and fluor protector N (FP, 7700 ppm F). Five samples were collected from each varnish. Further, 10 mg of each varnish were applied onto an acrylic surface (diameter, 5 mm) and then immersed in 20 mL of distilled water at 37degrees C. The fluoride concentration in each sample was then analyzed after 30 min, 1, 2, 3, and 4 h, and after 4 days of exposure. RESULTS: The cumulative amount of fluoride released by FC (5.64+/-1.10 ppm) was significantly higher than that released by other products after 30 min. FC (8.55+/-1.85 ppm) and MI (8.21+/-0.81 ppm) released a significantly higher cumulative amount of fluoride after 4 h. The cumulative rate of fluoride released by FC (47.80+/-9.35%) was significantly higher than that of other products after 30 min. FC (72.44+/-15.68%) and MI (69.54+/-6.88%) showed a higher cumulative fluoride release rate after 4 h. MI sustainably released fluoride after 4 h and demonstrated a high fluoride release rate of 95.76%. CONCLUSIONS: The cumulative amount and rate of fluoride released by several varnishes were statistically significant at each time point. This data can be used by clinicians prior to selection of dental products.

4.Association between cigarette smoking status and periodontal disease in adults: results from the 2012 Korea national health and nutrition examination survey.
Journal of Korean Academy of Oral Health 2016;40(2):133-139
OBJECTIVES: The aim of this study was to evaluate the association between smoking status and periodontitis risk in Korean adults. METHODS: This study used data collected from the 2012 Korea National Health and Nutrition Examination Survey. The final sample included 5,513 subjects over 19 years of age who had completed the necessary health behaviors survey and health examinations. RESULTS: First, based on a stratification analysis by gender, women who smoked more than 20 cigarettes daily had a 9.99-fold greater risk of periodontal disease than men. The risk of periodontal disease was higher in patients who began smoking at a later age. In patients with less than 20-40 lifelong smoking years, there was an increased risk of periodontitis, especially in men. Second, in a stratification analysis based on the presence of diabetes, patients with diabetes and a history of past smoking had a 2.53-fold higher risk of periodontal disease than non-smoking patients with diabetes. In both healthy and diabetic patients, the risk of periodontal disease increased with the daily smoking quantity and with age, and was also increased in individuals with less than 20-40 lifelong smoking years. The risk of periodontal disease was higher in the diabetes group overall, regardless of smoking status. CONCLUSIONS: These results suggest that a high level of smoking can increase periodontal disease risk independently of sex and the presence of diabetes in Koreans. This study implies that smoking may be an independent risk factor for periodontal disease.

OBJECTIVES: The purpose of this study was to analyze the pattern of dental caries in a high-risk group of Korean adolescents. METHODS: Raw data on 10,542 adolescents between the ages of 12 and 15 years from the 2012 Korean National Oral Health Survey was used. The subjects were divided into a high caries risk group and non-high caries risk group for analysis. For the statistical analyses, we utilized a frequency analysis, descriptive statistics, and a multidimensional scaling analysis. RESULTS: The pattern of dental caries in the high caries risk group were divided into six classifications for 12-year-olds and five for 15-year-olds, including the mandibular first molar occlusal surface (Cluster 1). In the high caries risk group, the frequency of Cluster 1 was approximately 4-times higher in 12-year-olds than that in the non-high caries risk group of Cluster 1, and about 3-times higher in 15-year-olds. The multidimensional scaling analysis found that in the high caries risk group, the same types of tooth surfaces formed separate groups. The prevalent dental caries pattern of 12-year-olds in the high caries risk group was left-right symmetry, while in the 15-year-olds of the high caries risk group, the caries pattern also included the antagonistic teeth, along with left-right symmetry. However, the non-high caries risk group had a pattern of left-right symmetry only in the 15-year-olds. CONCLUSIONS: When dental caries occur in the first molar, there is a high possibility of being classified into the high caries risk group. Therefore, preventative measures should focus on the antagonistic teeth and the teeth on the opposite side.

6.Effects of socioeconomic level on dental scaling experience in the community: a multilevel analysis.
Journal of Korean Academy of Oral Health 2016;40(2):118-125
OBJECTIVES: The purpose of this study was to investigate the associations between a community-level factor and dental scaling experience and to confirm the associations with individual factors in Korea. METHODS: In total, 203,088 individuals from 243 communities participated in the 2013 Community Health Survey. A dichotomized response of experiences with dental scaling was used as the outcome and the regional deprivation index was used as the explanatory community-level factor. In addition, various individual factors were included as covariates. In the bivariate analysis, the chi-square test was used. Multilevel multivariate logistic regression was also performed where in four models were applied. The bivariate analysis showed that all factors at the individual and community level showed significant associations with an individual's experience with dental scaling. RESULTS: The factors that were significantly associated with the dental scaling experience were being male, being 40-49 years old, having a higher income level, being economically active, having a higher education level, being a non-smoker, being a drinker, having good periodontal health, using oral hygiene products, tooth-brushing after lunch, and residing in less deprived regions (P<0.01). As with the results of multilevel logistic regression analysis, the regional deprivation index was significantly associated with scaling experience after adjusting for individual factors with an adjusted odds ratio of 0.98 (95% CI: 0.97-0.99), demonstrating an association between a lack of experience with scaling and lower socioeconomic status in the community. CONCLUSIONS: This study indicated that the scaling experience was affected not only by individual factors, but also by factors at the community level. Future studies are required to examine the detailed relationships between oral health and other community factors such as medical and social capital.

OBJECTIVES: Many people rely on recommendations from family, relatives, and other information sources in order to select the appropriate dental clinic for treatment. The object of this study was to find out the relationship between quality of dental service and Korean Net Promoter Score (KNPS). METHODS: A total of 520 patients were selected through consecutive sampling from four dental clinics in Daegu city. Informed consent of all selected patients was obtained. The patients were required to complete a questionnaire that comprised of three categories of queries related to provision of satisfactory dental service, relation quality, and personal data. Sub-categories of questions included physical and environmental factors, human service factors, patients' satisfaction with related quality and KNPS. Data was collected by interviewing all individuals on a personal basis over a period of 3 months. Statistical analysis was performed using studental t-test, ANOVA and multiple regression analysis using the SPSS 20.0 software (IBM Co., Armonk, NY, USA). RESULTS: Among the various socio-economic factors studied, income was most significantly related to KNPS while satisfaction of relation quality was the largest factor affecting the KNPS. Factors such as satisfactory physical environment, quality of human service, relation quality and income accounted for 52.4% of KNPS. In short, the three major factors that affected KNPS were patient compliance, professionalism of the attending dentist and response of hygienist to patient. Other minor factors influencing KNPS included trust upon the attending dentist, aesthetics of clinicstiinterior, and physical convenience. CONCLUSIONS: It is highly recommended that dental clinics should make strenuous efforts to increase the level of patient compliance, professionalism, and response towards patients, which can be achieved by improving the quality of service and through positive marketing of the hospital.

Journal of Korean Academy of Oral Health 2016;40(2):105-111
OBJECTIVES: The objective of this study was to examine the difference in dental care utilization between diabetics (diabetes group) and nondiabetics (normal group). METHODS: We examined the data of 5108 subjects enrolled in the Korea Health Panel Survey, every year for three years between 2010 and 2012. Of these, 458 subjects were included in the diabetes group and 458 in the normal group using the propensity score matching method to control confounding variables. To compare dental care utilization by the diabetes and normal groups, we examined the odds ratio (OR) and 95% confidence interval (CI) using a generalized estimating equation. RESULTS: We found that the odds of dental care utilization by the diabetes group compared with the normal group was significantly high (OR=1.82, 95% CI: 1.60-2.09). The result was consistent according to sensitivity analysis (OR=1.96, 95% CI: 1.63-2.35). CONCLUSIONS: Dental care utilization by the diabetes group was 82% higher than that by the normal group. Therefore, patients with diabetes need to be more concerned about oral health care.

9.Effect of health behaviors on oral health in Korean adolescents.
Journal of Korean Academy of Oral Health 2016;40(2):100-104
OBJECTIVES: Adolescence is a time during which health behaviors and attitudes that significantly affect the quality of life are formed. The aim of this study was to analyze data from a large national survey to determine the effect of health behaviors and the DMFT index as well as oral and general health behavior patterns on oral health in adolescents. METHODS: Data from the Fifth Korea National Health and Nutrition Examination Survey were used to analyze the association between health behaviors and the DMFT index in Korean adolescents. The data were analyzed using SAS version 19.3. Multiple regression analysis was used to assess the relationship between the variables, and 95% confidence intervals were computed. RESULTS: Sex, age, private medical insurance coverage, usage of oral-hygiene-assistance products, lack of dental treatment, and the status of self-recognition of oral health were the factors that had a significant influence on oral health among adolescents. CONCLUSIONS: The study findings provided further evidence supporting the promotion of school-based oral health programs and highlighting the need of oral health education for adolescents.

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.
