Zusammenfassung:	To provide a biodegradable dental barrier film and a method for producing the same in which the dental barrier film that is thoroughly wetted by and after reducing soaking time and wetting time before use has better covering and fitting property.SOLUTION: The dental barrier film includes a biodegradable porous substrate layer and a hydrophilic substance. The hydrophilic substance is bound to the biodegradable porous substrate and is selected from the group consisting of hyaluronic acid or derivative thereof, and water-soluble vitamin. Thus, the outer surface of the dental barrier film has a hydrophilic property having a water contact angle of less than 80°.SELECTED DRAWING: Figure 1 【課題】使用前の浸漬・濡れ時間を低減した上で、十分に湿潤した歯科用バリアフィルムは、より優れた覆いフィット性を有する、生分解性を有する歯科用バリアフィルム及びその製造方法を提供する。【解決手段】歯科用バリアフィルムは、生分解性多孔質基層及び親水性物質を含む。親水性物質は、生分解性多孔質基層に結合すると共に、ヒアルロン酸又はその誘導体、及び水溶性ビタミンからなる群から選択される。このように、歯科用バリアフィルムの外表面に水接触角が８０°未満の親水性を有する。【選択図】図１
