The purpose of this study is to identify if dental patients discriminate between dental clinic and dental hospital and the related factors for choice of dental facilities. A self-administered questionnaire survey was conducted from March 21 to April 11, 2011. Among 430 dental patients who visited dental clinic or dental hospital twice or more in Daegu, 410 dental patients were included in analysis. A total of 73.6% of the dental clinic visitors recognized correctly that the visiting facility was dental clinic and 82.3% of dental hospital visitors did correctly. Therefore, it can be said that dental hospital visitors recognize better the type of dental care facilities they visit. When it comes to choosing the dental facility, there were not much differences between the clinic and hospital patients in this study. Human resources, facilities and equipment, service are factors for choosing dental clinic and dental hospital in order. However, modern dental facility and equipment were more important factor for patients to choose dental hospital than clinic. It will be necessary for dental clinic or dental hospital to develop its own specific service to fulfill dental patients' needs through further studies on factors for choosing dental facilities.
