Objectives: Using the annual data from the 2016 Korean Health Panel, this study aims to identify the factors that affect the dental utilization and expenditure of patients with chronic diseases, and to provide basic data to explain the inequality gap in dental utilization. Methods: The dental utilization and expenditure of 3,557 patients with chronic diseases were analyzedfor frequency using the SPSS Windows version 23.0 (SPSS Inc. IL, USA). Analysis of the factors that affect dental utilization and expenditure were performed using a multiple regression analysis. The level of statistical significance was 0.05. Results: The frequency of dental utilization in patients with chronic diseases was high for subjects who were younger than 65 years and those whose education level was below high school. The frequency of dental utilization was relatively lower for subjects who did not have disabilities and those with healthier subjective health status. The dental expenditure of patients with chronic diseases was higher in subjects who were younger than 65 years and those with greater household income. Conclusions: The above findings suggest that a plan is needed to control dental utilization by efficiently managing chronic diseases, and that a policy-based plan is needed to devise ways to supplement the uninsured medical expenses of dental care.

Objectives: Receiving proper dental care plays a significant role in maintaining good oral health. We investigated the relationship between regional deprivation and dental care utilization. Methods: Multilevel logistic regression was used to identify the relationship between the regional deprivation level and dental care utilization purpose, adjusting for individual-level variables, in adults aged 19+ in the 2008 Korean Community Health Survey (n=220 258). Results: Among Korean adults, 12.8% used dental care to undergo examination and 21.0% visited a dentist for other reasons. In the final model, regional deprivation level was associated with significant variations in dental care utilization for examination (p<0.001). However, this relationship was not shown with dental care utilization for other reasons in the final model. Conclusions: This study's findings suggest that policy interventions should be considered to reduce regional variations in rates of dental care utilization for examination.

Objectives: This research is to provide the basic data for the improvement on oral health by examining the relationship between the dental fear and the dental service utilization, and to discuss a strategy for dental health in order to lower the level of dental fear. Methods: Data were collected by conducting a structured survey of 1,607 people between the age of 13 and 70 who have experiences in visiting a dental institution. Both univariate and multivariate analyses were employed to analyze the relationship between the number of times dental service and dental fears. Results: The average level of dental fear the respondents reported was $52.16{\pm}15.71$ and 31.5% of the response was at the level of high dental fear. A strong physiologic response during the dental treatment was muscle tension and the stimulations that strongly arouse the dental fear were the anaesthetic needle and the sound of drill. A result of analysis on the relationship between the dental fear and the dental service utilization shows that as the level of dental fear became higher, the number of times for the dental service utilization for the last year had reduced. Also when a patient has an experience of putting off or canceling an appointment due to dental fear and as a physiologic response during the dental treatment became stronger, the result shows a tendency that the number of times for the dental service utilization for the last year had reduced. Conclusions: It has been observed that dental fear is one of the main barrier to use dental service. Therefore, a physio-psychological factor like the dental fear should be included in the task of promotion of dental health, and in analyzing the dental service utilization behavior. A discussion about how to lower dental fear was made with respect to oral health promotion. At individual level, improvement of communication skill by dental service providers should be made with rearrangement of clinic environment into more cozy one.

The purpose of this study was to examine dental care utilization and expenditures among children aged 0 to 19 years using Korea Health Panel Survey (KHPS) data in 2008 - 2013. Weighted estimates were nationally representative and statistical significances were analysed by $x^2$ test or adjusted Wald test using STATA 13 software. While dental care utilization increased steadily among children from 2008 through 2013, less than one-third the children received dental care in 2013. Compared with 2008, the proportion of restorative care, oral surgery, preventive care decreased and the proportion of orthodontic care, prosthetic care increased. While the proportion of amalgam markedly decreased, the proportion of resin increased. This study highlight socioeconomic disparities in dental utilization and expenditures among children. Especially the findings provide a baseline assessment for examining trends on dental care for children in the future.

A dental implant has been covered by National Health Insurance (NHI) in Korea since 2014. Every year the age group covered was extended and the out-of-pocket payment was decreased. This study analyzed the dental implant utilization rate by the National Health Insurance customized DB during the last 5 years. As a result, the utilization rate has been rapidly increasing steeply. The differences by age and sex in the utilization rate of dental implants were explored. The inclusion of a dental implant in the NHI system contributed to improving the dental accessibility of the elderly in Korea. However, a deep discussion is needed whether it is appropriately provided to necessary patients. The utilization rate will increase further in the future. Therefore, continuous monitoring and critical policy review should be continued.

Objectives: The demand for dental care is expected to increase as the population ages. This study aimed to predict the utilization of dental implant care following the expansion of national health insurance benefits for dental implants. Methods: Multiple linear regression analysis was performed on HIRA big data open portal data and DNN-based artificial intelligence models to forecast the utilization of dental care in relation to the national health insurance coverage for dental implants. Results: National health insurance coverage of dental implants was found to be associated with the number of patients using dental implant services and demonstrated a statistical significance. The dental implant services utilization increased with the increased dental implant health insurance benefits for the elderly population, increased mean by region, increased number of dental institutions by region, and increased health insurance coverage rate for dental implants. However, the dental implant services utilization decreased with the increased number of older people living alone and increased size of dental institutions. Conclusions: With the expansion of the national health insurance coverage for dental implants, it is predicted that the utilization of dental implant medical services will increase in the future.

Objectives: The objective of the study was to investigate the related factors of non-utilization of dental care among Korean adults. Methods: Korean National Health and Nutrition Survey 2012 was carried out in South Korea. A total of 5,589 adults were interviewed and examined. A multinominal logistic regression model was used to estimate the odds ratio with 95% confidence intervals for the non-utilization of dental care. Results: The non-utilization of dental care was shown to have a badly perceived oral health status, less toothbrushing before sleeping(OR=1.18: 95% CI=1.00-1.39), periodontitis symptoms (OR=1.82: 95% CI=1.50-2.22), toothache experience (OR=2.03: 95% CI=1.75-2.34), TMJ symptom experience (OR=3.31: 95% CI=2.74-3.99), speaking problem (OR=1.87: 95% CI=1.75-2.34) and a partial dentures needs (OR=2.49: 95% CI=1.93-3.19). Conclusions: The non-utilization of dental care tended to have badly perceived oral health status, less toothbrushing before sleeping, periodontitis, toothache experience, TMJ symptom experience, speaking problem, and partial dentures needs.
