Comparison of the oral health status before and after preventive scaling using the provision of national health insurance: The 5th-6th Korea National Health and Nutrition Examination Survey

Objectives: The purpose of this study was to compare the oral health statuses pre- and post-insurance using the $5^{th}$ and $6^{th}$ National Health and Nutrition Examination Survey data to confirm the effect of scaling insurance after a year. Methods: Data were analyzed using IBM SPSS ver. 21.0 (IBM Co., Armonk, NY, USA). The four years were integrated, and a composite sample analysis was performed. A total of 26,990 people were included in the study before applying for scaling insurance (14,343 persons) or after receiving scaling insurance (12,647 persons). A chi-squared test was performed to compare the demographic characteristics and oral health status of the subjects. The significance level of the statistical test was 0.05. Results: The proportion of patients without implants was high before the provision of scaling insurance once a year, however, the proportion of patients with one or more implants was high (p<0.05) after the provision of scaling insurance once a year. Hemorrhagic periodontal tissues and tartar formation in periodontal tissues were highly prevalent before the provision of scaling insurance once a year, however, healthy periodontal tissues and formation of periodontal pockets were highly prevalent (p<0.05) after the provision of scaling insurance once a year. The decay, missing, and filled teeth index scores were higher before the provision of scaling insurance once a year (p<0.05). Conclusions: The aforementioned results showed that scaling once a year helps prevent or treat periodontal disease. In addition, we confirmed the effect of prevention on periodontal disease and dental caries, therefore, we expect it to develop into a stable policy.
