PROBLEM TO BE SOLVED: To provide a packing/restoring material for dentistry capable of curing a pre-treating material and the packing/restoring material by one step light irradiation in dental treatment, and also excellent in the bonding strength of an inner wall of a cavity with the packing/restoring material.SOLUTION: This packing/restoring material kit for dentistry is characterized by having the packing/restoring material containing a radically polymerizable monomer without having an acid group, a filler and a photopolymerization initiator, and a pre-treating material containing an acid group-containing radically polymerizable monomer and water, containing a titanocene-based photopolymerization initiator in at least one of the members selected from the packing/restoring material and the pre-treating material, applying the pre-treating material on the cavity, then filling the packing/restoring material at the inside of the cavity applied with the pre-treating material and then irradiating visible light to the cavity part filled with the packing/restoring material to cure the same and also bond the wall surface of the cavity with the filled packing/restoring material in the dental treatment.COPYRIGHT: (C)2011,JPO&INPIT【課題】歯科治療に際して、1ステップ光照射により前処理材および充填修復材を硬化させることができる上に、窩洞内壁と充填修復材との接着強度にも優れること。【解決手段】酸性基非含有ラジカル重合性単量体、フィラーおよび光重合開始剤を含む充填修復材と、酸性基含有ラジカル重合性単量体および水を含む前処理材と、を有し、充填修復材、および、前処理材から選択される少なくとも一方の部材に、チタノセン系光重合開始剤が含まれ、歯科治療に際して、前処理材を窩洞に塗布し、次に、前処理材が塗付された窩洞内に充填修復材を充填し、続いて、充填修復材が充填された窩洞部分に可視光を照射することにより充填修復材を硬化させると共に窩洞壁面と窩洞内に充填された充填修復材とを接着することを特徴とする歯科用充填修復キット。【選択図】なし
