動機與目的：
精神疾病患者受到精神疾病影響日常行為能力，口腔健康狀況普遍不佳，牙醫門診醫療利用困難度比一般人高。本研究旨在探討精神疾病患者牙醫門診醫療利用情形，並以Aday & Anderson發展的醫療服務行為模式來分析其影響因素。
研究方法：
採用全民健保學術研究資料庫所提供的「2002-2007年精神疾病住院病患歸人檔」作為資料來源，有效樣本為95,435人，並使用描述性分析、Student t-test、單因子變異數分析，探討精神疾病患者牙醫門診醫療利用情形與相關影響因子。
結果與結論：
全體研究對象之利用牙醫門診醫療比率為34.01％，每年平均牙醫門診醫療利用次數為1.24次，年平均牙醫門診醫療利用總費用為1420.58元。在影響因素方面，女性之利用次數及費用皆較高；年齡層以20歲以下利用次數與費用皆為較高；投保身分以其他身分者其利用次數與醫療費用皆較高；投保金額以40001元以上平均利用次數與費用皆為較高；投保地區連江縣平均每人每年利用次數與費用為較高；每萬人口牙醫師數6名以上平均利用次數與費用為較高；是否為低收入戶利用次數與費用皆無顯著差異；免部分負擔者之醫療次數高於需部分負擔者，費用上無顯著差異；重大傷病者之利用次數與費用高於非重大傷病者。
建議：
（1）加強精神病患自我及其照顧者口腔衛教資訊之宣導；（2）針對青少年與兒童族群規劃完善之口腔健康管理；（3）重視偏鄉地區口腔衛生宣導與照護品質：（4）修訂全民健康保險牙醫門診總額特殊醫療服務於精神病患之給付；（5）建立身心障礙牙醫專業人才培育制度；（6）針對牙醫師人數進行合理控管與分配。 Background and Objectives:
