Purpose: This study was carried out in order to examine organizational commitment in dental technicians and turnover intention level according to it, and to analyze its effects. Methods: A self-reported questionnaire survey was carried out by having convenience sampling as 200 dental technicians. An analysis of the collected data was computationally processed by using SPSS Win 19.0 program. An analytical technique was made by using statistical techniques such as frequency & percentage, t-test, One-way ANOVA analysis. The following are the analytical results of the collected materials. Results: In consequence of analyzing organizational commitment level in research subjects, there was a significant difference in the items for age, task field, job position in charge, career in dental laboratory technology, and monthly income(p<.05). The average of the item for organizational commitment level stood at 3.29, thereby having been indicated to be high. As a result of analyzing turnover intention level in research subjects, there was a significant difference in the items for task field, job position in charge, career in dental laboratory technology, and monthly income(p<.05). The average of the item for turnover intention reached 3.04, thereby having appeared to be relatively high. As for a correlation between organizational commitment and turnover intention, all variables were shown to have inverse correlation at a significant level. In consequence of conducting regression analysis in order to analyze the influence of organizational commitment upon turnover intention, a factor of having the most impact on turnover intention appeared to be normative commitment. The test value of the model was statistically significant. The explanation power about this was indicated to be 26.9%. Conclusion : In the above findings, the dental technicians are considered to need to be immersed in work with a sense of mission in performing job in charge, to strive to possibly have an opportunity of achievement and self-growth, and to perform a research and development in a manpower management strategy such as turnover prevention.

Purpose: This study aimed to investigate the perception of dental implant insurance supply and demand for the elderly living in Hongseong-gun and Chungcheongnam-do, as well as the selection criteria regarding dental clinics for dental implant treatment to collect basic data for improving the oral health of the elderly population. Methods: Participants living in Hongseong-gun, Chungcheongnam-do who were at least 55 years old from November 2020 to March 2021 were included in this study. The chi-square test was performed to examine the age-specific perception of insurance-covered dental implants (p<0.05). Results: The age group that was the most interested in implants was the 70s age group, and the difference between this age group and the other age groups was statistically significant. Those in their 70's, 80's, and 90's or older paid about 600,000 won including dental implants covered by insurance, and there was a significant difference (p<0.05). Those in their 60s, 70s, and 80s estimated the highest value of implants covered by insurance as two and showed a significant difference (p<0.05). The awareness of the dental implant insurance by age showed that all age groups, except for the ≥90 years age group, considered the insurance to be mediocre mostly due to the large co-payment (p<0.05). Conclusion: There were differences by age in the awareness of dental implant insurance, co-payments, number of applications, and insurance coverage. The perceptions on dental implant insurance by age showed that all age groups except for those over 90 years and older, they considered the insurance was just mediocre the most.

Background: With increased interest in oral health, several efforts have been made to improve oral health conditions. To achieve this, needs for oral health must be precisely determined and accurately measured. Therefore, factors influencing both objective unmet dental needs, which were determined by experts, and perceived unmet dental needs, which were determined by patients, were examined in this study. Methods: Responses of 17,735 respondents aged greater than 19 years from the Korean National Health and Nutrition Survey collected using the fifth (2010~2012) rotation sample survey were analyzed. Based on the information collected from the survey and dental examination, we determined the associations between the independent (sex and socioeconomic level) and dependent variables using a chi-squared test. Moreover, ordinal logistic regression analyses on multiple categorical values were performed using perceived and objective dental needs as the dependent variables. Results: Generally, factors influencing both perceived and objective dental needs were similar. These included sex, household income, educational level, private insurance, and subjective oral health status. However, the high-income groups had lesser perceived and objective dental needs compared to the low-income groups. Furthermore, factors such as sex, educational level, and marital status had different influence on both needs. Conclusion: Generally, factors that affect perceived and objective dental needs were similar. To minimize unmet dental needs, factors influencing both perceived and objective dental needs should be examined for a broad dental insurance coverage, and efforts to prevent oral diseases are also required.

This study examined the opinions of dentists on dental hygienists' practice and attempted to use it as the basis for the revision and modification of the legal system associated with dental hygienists. The subjects of this study were a total 15 dentists, including two from Gyeonggi, two from Gangwon, two from Gyeongsang, two from Jeolla, two from Chungcheong, and two from Seoul, who were surveyed face-to-face. This study revealed that from the perspective of dentists, the most important job of dental hygienists was scaling, and the most difficult job was patient counseling and response. From the perspective of dentists, there is a difference between what the dental hygienists actually perform and what is legal, and there is a high need for change. The inclusion of dental hygienists in the category of medical personnel should be accomplished to cover the practice of dental care support, and dentists opinionated that it is appropriate for dental hygienists to be included in the category of medical personnel because they directly perform oral health-related procedures. A careful review of the dental hygienists' scope of work should be performed to ensure that revisions to the law are made in accordance with the dental hygienists' actual practice. Further, it is necessary to revise the Medical Law and include dental hygienists among the medical personnel and simultaneously revise the scope of work of dental hygienists to reflect the actual dental practice.
