為了控制持續上漲的醫療費用，全民健康保險局已於1998年實施牙醫總額支付制度。總額支付制度的實施，除了控制醫療費用之外，還會影響到牙醫師的診療相關活動與牙醫品質。本論文旨在探討支付制度對於醫療供給者診療行為的影響，以牙醫總額支付制度為實證研究對象。本研究之研究母體為臺灣地區執業牙醫師，資料蒐集是以郵寄問卷方式進行普查，請牙醫師本人親自填答。研究結果發現牙醫總額支付制度實施前後，牙醫臨床診療相關活動有顯著提升者包括：初診與複診患者採取預約制度、以牙周探針確認牙周狀況、治療不同患者時戴新口罩與新手套、進行口腔衛教、評估治療完成度，以及後續轉診至膺復牙科、牙周病、口腔外科專科醫師。研究結論為牙醫總額支付制度對於牙醫師臨床診療相關活動的影響，多數屬於較正面效果。
