Objectives: The purpose of this study was to investigate the correlation between tooth extraction and endodontic treatment according to the inclusion of dental implant coverage in National Health Insurance of Korea, which is a recent dental health insurance policy change. Methods: From July 2011 to June 2016, using the health care big data open system in National Health Insurance of Korea, we analyzed the number of patients, the total amount of use, and the amount of health care service. Results: Age-standardized incidence rate, amount of treatment, and total usage of both the extraction and endodontic treatment increased after July 2014, and July 2015. Conclusions: The increase in the age-standardized incidence rate, the amount of treatment, and the total amount of usage after the change of the health insurance policy shows the result supporting the hypothesis of the supplier attraction demand theory. Health care policies have proven to influence dental practice. Without sufficient discussion and evidence-based indications, more dental health insurance coverage would fail to get the health policy goals and may result in poor quality of care or excessive health care expenditure. Therefore, sufficient discussion with expert group will be needed in health insurance policy formation and expanding health insurance coverage.
