This study focused on the change of environment and cognition of dental hygienists about dental calculus removal after the national health insurance. We conducted online and offline surveys for 290 dental hygienists working in dental clinics in Seoul, Gyeonggi and Incheon areas. Differences in perceptions were assessed by independent t-test and ANOVA. 62.1% answered that the health insurance coverage of dental calculus removal was appropriate, and 49.6% said that the desired number of health insurance coverage about the dental calculus removal should be applied twice a year. 54.3% said that the age after 20 years-old was not appropriate in national health insurance coverage of dental calculus removal, and 49.3% said that the appropriate starting age of dental calculus removal should be applied from high school students. 26.3% said that the number of national health insurance applications should be increased yearly, 20.5% said that oral care education should be added. Most of the dental hygienists said that the number of scaling patients increased, but that the quality of the scaling did not deteriorate. According to general characteristics, in the recognition of the removal of calculus, the dental hygienists having a career for 7~8 years felt less change. The dental hygienist wanted to expand the scope of national health insurance about scaling removal so that more subjects could remove dental calculus removal. Dental hygienists wanted that national health insurance should be systematically supplemented in order to contribute to the promotion of oral health of the people.

Priority setting in national health insurances in major advanced countries and the nation was investigated to draw the criteria for priority setting and suggest the most rational criteria for dental insurance so as to help secure the efficiency of medicare financing and individual's health right and also elevate medical consumers' satisfaction with health insurance. 1. Priorities in national health insurance are different from country to country, depending on the medical security systems, priority introducing conditions, and social environment, but have many common factors. 2. The priority setting criteria for national health insurance in those countries include the following in common: the efficiency, equity, and cost effect of treatment, emergency of treatment, consumption of expense, efficacy of treatment, patient's receptiveness, patient's demand, severity of disease, and patient's responsibility for the disease. 3. In oral diseases, severe diseases including oral cavity cancer are low in rate, and in-hospital treatments are few. From the above findings, it is suggested that dental insurance should establish discriminative criteria for priority setting by reflecting the aspects of dental diseases and system difference between dental and other health insurances and taking account of efficiency of treatment through prevention, cost effect, prevalence and incidence of generalized diseases, and individual's financing burden.

Purpose: The purpose of this retrospective study was to investigate the relationships of types of dental insurance coverage in Korea with sociodemographic characteristics and the prevalence of systemic and oral diseases, as well as to evaluate the socioeconomic impact of Korean dental insurance policies. Methods: Sample cohort data from 2006 to 2015 were obtained from the National Health Insurance Service. Patients were divided into 2 groups. The exposed group comprised patients who received insurance benefits for complete dentures, removable partial dentures, and implant care, while the control group comprised patients who did not receive these benefits. The type of insurance coverage and the prevalence of systemic and oral diseases were compared between the 2 groups. Results: Patients who received benefits in the form of complete dentures, removable partial dentures, and implants had similar sociodemographic characteristics in terms of sex, age, income quintile, and type of insurance coverage to the control group. The prevalence of hypertension, anemia, renal disease, rheumatoid arthritis, osteoporosis, asthma, and cerebral infarction was higher in the exposed group than in the control group (P<0.05). The prevalence of periodontal diseases and dental caries was also higher in the exposed group. Conclusions: Korean dental health insurance policy has been beneficial for the medical expenses of low-income and elderly people suffering from a cost burden due to systemic diseases. However, since there is a tendency to avoid invasive interventions in older patients due to the high risk of systemic diseases, insurance coverage of dentures may be more helpful from a socioeconomic perspective than coverage of dental implant treatments.
