The purpose of this study is to investigate the regional change of dental scaling experience by scaling insurance coverage in July, 2013. The data were used in the "Community Health Survey" of the 2012 and 2014. The results of the study are as follows; 1) The subjective oral health status and brushing of lunch was highest in Gangnam-gu in both 2012 and 2014(p<0.001). 2) Regular dental check-up was high in Gangnam-gu in both 2012 and 2014(p<0.001). 3) The Scaling experience rate increased in all three regions(p<0.001). 4) The socio-demographic characteristics and scaling experience were higher in 2012 and 2014(p<0.001). The scaling experience was higher when there were office workers and spouses(p<0.001). From the policy perspective, it seems necessary to take measures to reduce the gap in scaling experience rate due to differences in income and unequal medical environment.

The aim of this study is to investigate the awareness and perception of pediatric dentists regarding dental health insurance (DHI) system in Korea. Online surveys were sent to the members of the Korean Academy of Pediatric Dentistry (KAPD), and the responses were collected. The survey, consisting of 41 questions, was subdivided into 'general background of the respondents', 'the awareness on national health insurance (NHI) and DHI', 'the awareness on DHI pertaining to pediatric dentistry', 'issues that need improvement on DHI pertaining to pediatric dentistry', 'DHI claims', and 'the roles of KAPD in DHI'. In total, 302 responded, with a response rate of 28.9%. Excluding 2 questionnaires with insufficient answers, a total of 300 survey results were analyzed. According to the analysis, pediatric dentists thought that the coverage of DHI was not as sufficient compared to that of NHI, but were expecting its scope to broaden in the future. The satisfaction rate was higher in pit and fissure sealant and composite resin filling than in caries-detecting quantitative light-induced fluorescence. Pediatric dentists considered permanent tooth composite resin filling (65.7%) needed an increase in insurance copayment, while topical fluoride application (74.7%) to require insurance coverage. DHI claims were generally handled by dental hygienists and/or nursing assistants. Approximately half of the respondents answered that they have had experiences on appealing for insurance denials. Lastly, pediatric dentists generally had a positive attitude towards providing information for the DHI. This study is expected to be used as a sound dataset for the DHI policy development concerning pediatric dentistry.

Objectives: The purpose of the study is to investigate the related factors to dental care utilization, oral health behaviors, and oral health status in immigrant workers in Korea. Methods: The subjects were 504 foreign immigrant male workers over 20 years old who visited Daegu labor consultation center for oral health survey and oral examination. The questionnaire included 5 questions of socioeconomic characteristics, 8 questions of oral health practice behavior, 6 questions of dental clinic visit, 8 questions of social relations and Korean language proficiency. The question for health behavior was measure by body mass index(BMI). Social relations and Korean language proficiency instrument was modified by Seol from "Family welfare survey in Korean international marriage" and scored by Liker 5 scale. Results: The oral health examination of the immigrant workers was as follows: decayed teeth - 76.6%, filling teeth - 27.4%, missing teeth - 69.8%, dental caries experience above five or more - 60.2%, periodontal pocket tissues - 58.9%. Simplified Oral Hygiene Index was very poor and accounted for 49.0%. Dental care utilization experience was closely associated with social relation indexes including attendance in family events, household stuff help, financial help and counseling for hard work(p<0.01). Dental care utilization experience proportionally increased with proficiency in Korean literacy including speaking, listening, and writing abilities of Korean language(p<0.01). Conclusions: In order to improve the oral health condition of the immigrant workers, it is important to provide social network, Korean language proficiency support, and health insurance coverage through economic burden reduction by the Korean government.

Objectives: Protecting people against financial hardship caused by illness stands as a fundamental obligation within healthcare systems and constitutes a pivotal component in achieving universal health coverage. The objective of this study was to analyze the prevalence and determinants of catastrophic health expenditures (CHE) in Iran, over the period of 2013 to 2019. Methods: Data were obtained from 7 annual national surveys conducted between 2013 and 2019 on the income and expenditures of Iranian households. The prevalence of CHE was determined using a threshold of 40% of household capacity to pay for healthcare. A binary logistic regression model was used to identify the determinants influencing CHE. Results: The prevalence of CHE increased from 3.60% in 2013 to 3.95% in 2019. In all the years analyzed, the extent of CHE occurrence among rural populations exceeded that of urban populations. Living in an urban area, having a higher wealth index, possessing health insurance coverage, and having employed family members, an employed household head, and a literate household head are all associated with a reduced likelihood of CHE (p<0.05). Conversely, the use of dental, outpatient, and inpatient care, and the presence of elderly members in the household, are associated with an increased probability of facing CHE (p<0.05). Conclusions: Throughout the study period, CHE consistently exceeded the 1% threshold designated in the national development plan. Continuous monitoring of CHE and its determinants at both household and health system levels is essential for the implementation of effective strategies aimed at enhancing financial protection.

This study was conducted to identify factors related to discomfort while speaking in the elderly and provide fundamental data for establishing oral health care policies for a healthy old age. Using the raw data from the 8th wave of the National Health and Nutrition Examination Survey (2020), we conducted an analysis to examine the relationship between speaking discomfort and mental health, as well as oral health care behavior, among 1,278 elderly individuals in Korea. Differences in speaking discomfort were analyzed based on general characteristics, mental health, and oral health care behavior using complex sample cross-analysis. Additionally, factors associated with speaking discomfort were analyzed using complex sample multiple logistic regression analysis. As a result, individuals with depression experienced higher levels of speaking discomfort (p<0.05), and individuals experiencing high levels of stress also reported higher levels of speaking discomfort (p<0.05). As a factor affecting speaking discomfort, it was found that speaking discomfort was 2.56 times higher (p<0.001) when dental care was not met, and speaking discomfort was 3.05 times higher (p<0.05) when teeth brushing was less frequent. As a result of the aforementioned findings, it is believed that a customized oral health promotion program is necessary to expand dental health insurance coverage for the elderly and improve oral healthcare.

This study analyzed the tooth brushing behavior and oral health status of foreigner immigrant workers and obtained the following results. Statistical significance based on different general characteristics. Gender, educational background, period of stay, health insurance, medical expense coverage, and whether or not one has friends or regular gatherings were significant traits for frequency, while age, marital status, income, and health insurance were traits for part (p<0.05). Statistical significance (p<0.05) was found in marital status and health insurance for time used to brush teeth, period of stay and whether or not one attends a regular gathering for tooth brushing training, and gender, educational background, period of stay, roommate status, medical expense coverage, and whether or not one attends a regular gathering for supplemental oral product usage. The averages of decayed, missing, and filled teeth (DMFT) index and community periodontal index of treatment needs (CPITN) for general characteristics were 6.98 and 3.03 respectively, and gender, roommate status, income, health insurance for DMFT index, and gender, age, marital status, educational background, roommate status, income, health insurance for CPITN were statistically significant (p<0.05). Tooth brushing frequency and part showed statistical significance (p<0.05) for DMFT index based on tooth brushing behavior, while tooth brushing part and time used to brush teeth were significant for CPITN. DMFT index was high at 8.34 for '3 times or more' in tooth brushing frequency, while DMFT index was high at 7.91 and CPITN was low at 2.94 for tooth brushing part. '3 minutes or longer' in time used to brush teeth was the lowest in CPITN at 2.88. As a result of analyzing the correlation between tooth brushing behavior and DMFT index, CPITN, tooth brushing frequency and part in DMFT index, and tooth brushing part and time used to brush teeth in CPITN showed significance (p<0.05). Based on the above results, we must promote the significance of brushing teeth and implement continuous training for correct tooth brushing management to enhance the oral health of foreign immigrant workers.

This study was conducted to investigate treatment tendency and dental caries occurrence after receiving insurance coverage for pit and fissure sealing. Data were obtained from statements for insurance payments received by the Daejeon branch health insurance review and assessment service from December 2009 until December 31 2014. As to the Pit and Fissure Sealing current state by year, there was most a lot of the number of examinee and the treatment number of teeth in 2010. The per capita average treatment number of teeth was highest (3.39) in 2013. As to the result that it analyze the first molar Pit and Fissure Sealing in 2010 according to the general feature, man was high than the woman, it showed up by age in the age of 7 most highly, and the summer was the highest among by season. The upper jaw left first molar was the most common location, although the upper jaw on the right side first molar, lower jaw right side first molar, and lower jaw left first molar were also affected. In 2010, the procedure was conducted more in the upper jaw right side first molar and enforces the recharge since 2011 to 2014, men were treated more than women, the recharge which is the most abundant in the age of 7 was performed by age, and the procedure was performed more during summer than in other seasons. It is forecasted that at August, 2015 most high demand shows according to the result that it predicts the tooth treatment number until December 2015 based upon the treatment number of teeth from December 2009 until November 2014 and be reduced in comparison with the year 2014. Thus, tooth brushing alone is not sufficient to prevent dental caries. Indeed, conducting pit and fissure sealing in infants and toddlers, as well as elementary middle and high school oral health centers is expected to be effective at preventing dental caries.

Purpose: The purpose of this study was to analyze the level of interest that common Internet users have in dental implant using a Google Trends, and to compare the level of interest with big data from National Health Insurance Service. Materials and methods: Google Trends provides a relative search volume for search keywords, which is the average data that visualizes the frequency of searches for those keywords over a specific period of time. Implant was selected as the search keyword to evaluate changes in time flows of general Internet users' interest from 2015 to 2019 with trend line and 6 month moving average. Relative search volume for implant was analyzed with the number of patients who received National Health Insurance coverage for implant. Interest in implant and conventional denture was compared and popular related search keywords were analyzed. Results: Relative search volume for implant has increased gradually and showed a significant positive correlation with the total number of patients (P<.01). Interest in implant was higher than denture for most of the time. Keywords related to implant cost were most frequently observed in all years and related search on implant procedure was increasing. Conclusion: Within the limitations of this study, the public interest in dental implant was gradually increasing and specific areas of interest were changing. Web-based Google Trends data was also compared with traditional data and significant correlation was confirmed.
