Journal of Korean Academy of Oral Health.2016;40(2):133-139. doi:10.11149/jkaoh.2016.40.2.133

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.

Journal of Korean Academy of Oral Health.2016;40(2):126-132. doi:10.11149/jkaoh.2016.40.2.126

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.

Eun Sil CHOI ; Hae Young KIM

Journal of Korean Academy of Oral Health.2016;40(2):118-125. doi:10.11149/jkaoh.2016.40.2.118

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.

Journal of Korean Academy of Oral Health.2016;40(2):112-117. doi:10.11149/jkaoh.2016.40.2.112

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. doi:10.11149/jkaoh.2016.40.2.105

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.

Jae Kyung MA ; Min Jeong CHO

Journal of Korean Academy of Oral Health.2016;40(2):100-104. doi:10.11149/jkaoh.2016.40.2.100

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.

Journal of Korean Academy of Oral Health.2013;37(4):253-256. doi:10.11149/jkaoh.2013.37.4.253

OBJECTIVES: The purpose of this study was to develop a dentine hypersensitivity (DH) manual for a dental hospital. METHODS: The records of all DH patients who presented between 2005 to 2010 were analyzed to determine their age group, awareness of DH, and DH distribution before and after dental treatment. RESULTS: Out of 953,272 patients, data of 4,646 were analyzed. The male to female ratio of DH patients was found to be 1:1:1. The prevalence of DH was highest in patients in the age group of 40-49 years. The DH awareness rate was high to time, temperature and after dental treatment factor in the middle-age group. CONCLUSIONS: Since DH is widely prevalent and common, systematic screening is essential to ensure good oral health.

Eun Jeong KIM ; Kwang Hak BAE ; Se Hwan JUNG ; Bo Hyoung JIN

Journal of Korean Academy of Oral Health.2013;37(4):248-252. doi:10.11149/jkaoh.2013.37.4.248

The National Health Screening program has been implemented in Korea since 1980. First, we had searched recent scientific evidences and verified the accuracy of the data on target oral diseases. In order to determine the validity, we searched scientific bibliographic data and concluded that dental caries and periodontal disease were major oral problems. Second, we developed new improved forms for National Oral Health Screening. To improve these forms, we reviewed previous forms and gathered expert opinions. The new forms were consistent with the examination forms given to all age groups, and information on oral health conditions, dental education needs, and post-treatment care was included in the modified forms. We then designed manuals for dentists, which contained information on the screening criteria as well as consultation and patient education guidelines. The manuals were divided into three parts, including explanation of the screening criteria, standard of the decision, and education and consultation guidelines. By using these new and modified National Oral Health Screening forms, we expect an improvement in the National Oral Health Screening Program and enhancement in the oral health condition of patients.

Hye Rin LEE ; Deuk Sang MA ; Deok Young PARK ; Se Hwan JUNG

Journal of Korean Academy of Oral Health.2013;37(4):241-247. doi:10.11149/jkaoh.2013.37.4.241

OBJECTIVES: To verify the clusters of oral health-related behaviors by gender for adolescents in Gangneung, and to assess the influences of psychosocial factors (family socioeconomic status factors, individual economic factors, and psychological factors) on these clusters. METHODS: A survey was conducted of 3,611 adolescents (6th grade students in primary school, 2nd grade students in middle school, and 2nd grade students in high school) in Gangneung. The response rate was 96.6% (1,846 boys; 1,765 girls). The data were collected via self-administered structured questionnaires assessing participants 'smoking experience,' 'tooth brushing,' 'consumption of crackers or soft drinks,' and 'consumption of fruits or vegetables.' K-means cluster analysis was used to cluster the oral health-related behaviors by gender. A chi-square test was used to assess the difference between the clusters for oral health-related behaviors by gender and psychosocial factors. RESULTS: Clusters of oral health related-behaviors were classified into the unhealthy group (group 1; bad oral health-related behaviors), healthy group (group 2; good behaviors), and complex group (group 3; low smoking experiences and complex other behaviors). The clusters were different by gender. In the unhealthy group, boys represented 19.9% while, in the healthy group, girls represented 47.3%, which are both higher than the theoretical rates. Psychosocial factors in the unhealthy group were significantly lower than the healthy group (P<0.05). CONCLUSIONS: Meaningful clusters of oral health-related behaviors by gender were identified. Furthermore, the clusters were different by psychosocial factors. This finding suggests that one of the best ways to enhance oral health for adolescents is to develop oral health promotion programs for each oral health-related behavior cluster.
