Abstract Many studies about medial outcomes in rural areas or medial resource deficient areas have been published, but few discuss outcomes in areas deficient in oral medical resources. The program, improving underserved dental health care resources, has been implemented for near ten years, but no study explores the business models in different areas that are underserved dental health care resources. The purpose of this study is to compare different models of operating the program ¡§improving underserved dental health care resources¡¨. As to the business model, the program ¡§improving underserved dental health care resources¡¨ is executed in two main models. One is execution in fixed sites. The advantage of this model is high stability. Dentals can plan and set the equipments that they need to use. The other is medical tour. The advantage of this model is high flexibility, which let dentals can provide services as far as possible for patients in medial resource deficient areas. Finally, based on the research findings, this study proposes some suggestions, including that to use the medical-tour model as the major business to implement the program, to carefully assess the site for exestuation need, to consider the financial support on equipments (especially the dental mobile medical vehicle ), to strengthen local infrastructure investment is prior to plunge into health care resources, and so on.
