Objectives: The present study aimed to examine the perceptions and behaviors of dentists regarding the National Dental Health Insurance, and their opinions for improving its policies.
Methods: A self-report survey was conducted with 1,321 dentists selected from the Alumni Association of the W University College of Dentistry. We finally recovered and analyzed 243 questionnaires, excluding those returned with insincere answers. Results: Only 40.3% of the practitioners recorded the disease name, 12.8% of medical records were unrecorded, and 54.5% of the respondents did not receive the expenses borne by the principal. In addition, 14.0% of the practitioners had administrative dispositions or had been penalized with surcharge, and 74.6% of the respondents stated that dental care benefits should be expanded. Further, 92.2% of the respondents agreed that a course on dental health insurance should be offered at the university. Additionally, 80.6% of the participants stated that they were willing to participate in supplementary training programs that emphasize on dental health insurance. If supplementary training programs were to take place, 46.0% of the participants reported that they preferred courses that focused on dental health insurance in general, and 22.2% reported that they should focus on the decrease in health insurance. Finally, participants reported that insurance claims for each department had reduced for periodontal treatment (70.7%), other treatments (15.7%), and endodontic treatment (9.6%). Conclusions: It is necessary for dental practitioners to be educated on the National Health Insurance, in general, as well as on insurance claims.
